This also examines current challenges in drug repurposing and provides a critical review of the available opportunities and limitations in AI-assisted drug repurposing."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Elevated mitochondrial R-loop signal was also detected in a pilot cohort of sporadic ALS samples carrying rs2293925 and in neural stem cells derived from C9orf72-positive ALS patients.","status":"PASS","error":"","abstract_text":"ID: 42419740\nTitle: TOP1MT rs2293925 is an enhancer-active regulatory SNP that shapes mitochondrial R-loop dynamics.\nAbstract: Mitochondrial topoisomerase 1 (TOP1MT) regulates mitochondrial DNA (mtDNA) topology during transcription and replication. Perturbed mtDNA maintenance and RNA metabolism have been implicated in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). Here we show that the common TOP1MT variant rs2293925 (R525W) has enhancer-like activity and is associated with increased mitochondrial R-loops (RNA : DNA hybrids). Tissue-dependent expression, quantitative trait locus analysis, chromatin-state annotation, reporter assays, and allele-specific DNA-protein binding assays support a transcriptional regulatory role for rs2293925. In isogenic cell models, rs2293925 increased TOP1MT mRNA and protein abundance, and this was accompanied by increased mitochondrial R-loop signal. TOP1MT trapping with lamellarin D supported increased TOP1MT-R525W occupancy at mitochondrial control region sites together with enhanced R-loops, consistent with altered TOP1MT-mtDNA interaction and/or increased TOP1MT abundance. Elevated mitochondrial R-loop signal was also detected in a pilot cohort of sporadic ALS samples carrying rs2293925 and in neural stem cells derived from C9orf72-positive ALS patients. These data support a dual-effect model in which rs2293925 increases TOP1MT expression and is associated with altered mitochondrial R-loop dynamics, linking common genetic variation to mitochondrial nucleic acid stress in disease-relevant contexts."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease.","status":"PASS","error":"","abstract_text":"ID: 42411482\nTitle: Amyotrophic Lateral Sclerosis as a Systemic Disease: Why Integrative and Microbiome-Focused Approaches Deserve Re-Evaluation.\nAbstract: Despite decades of intensive research, therapeutic advances in amyotrophic lateral sclerosis (ALS) remain limited. Increasing evidence suggests that ALS is a multisystem disorder involving motor neuron degeneration, immune dysregulation, skeletal muscle pathology, and gastrointestinal dysfunction, thereby challenging the adequacy of current therapeutic strategies. Complementary and alternative medicine (CAM) approaches are widely used by patients with ALS. However, their efficacy remains controversial owing to limited clinical evidence and methodological limitations. The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease. The involvement of gut microbiome dysbiosis in the pathophysiology of ALS has provided a unifying biological framework linking the peripheral, metabolic, and neuroinflammatory processes. These findings suggest that the combination of CAM and conventional therapy may serve as a potential integrative approach to target gut-brain-muscle interactions and systemic disease pathways. This article highlights critical gaps in the existing evidence and proposes that microbiome-focused, biomarker-driven clinical trials are essential to thoroughly evaluate CAM-based interventions in ALS.

We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis.","status":"PASS","error":"","abstract_text":"ID: 42397462\nTitle: A case study of comprehensive association analysis and risk prediction of amyotrophic lateral sclerosis in a Chinese population.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease with significant genetic heterogeneity.

To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing.

We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (< 30 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts.

The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Simulated disease trajectories of MUNE values derived from CMAP scans in muscles affected by ALS indicated that MUNE may reach 50% of its maximum in approximately 60% of the time compared to functional impairment.","status":"PASS","error":"","abstract_text":"ID: 42434198\nTitle: Quantifying motor unit loss prior to functional impairment in muscles affected by amyotrophic lateral sclerosis.\nAbstract: The compound muscle action potential (CMAP) scan is a non-invasive method for deriving motor unit number estimates (MUNE) to track disease progression in muscles affected by amyotrophic lateral sclerosis (ALS). It remains to be established whether and how long motor unit loss precedes functional impairment. In 56 patients with ALS, we compared the longitudinal trajectories of MUNE derived from thenar CMAP scans, and fine motor function (FMF) using a functional rating scale. Linear and sigmoidal disease trajectories were modelled from which time differences were estimated between these measures to reach their half-maximum scores. The normalized linear decline per month was 0.02 (95% CI 0.01 to 0.03) for FMF and 0.03 (95% CI 0.03 to 0.04) for MUNE. Half-maximum of FMF was reached after 26.3 months (95% CI 18.9 to 35.1) for the linear model, while MUNE had a shorter time required to reach 50% of its maximum with 13.0 months (95% CI 10.3 to 16.4).

The Utah Neck Exoskeleton can restore neck motion, but current control methods-joystick and gaze tracking-have limited accessibility and reliability. These preliminary offline analyses investigate neck electromyography (EMG) as an alternative control modality from ALS patients. EMG signals were recorded from four male participants with ALS while performing neck flexion/extension, axial rotation, and lateral deviation. The resulting dataset was used to train convolutional neural networks (CNNs) per patient to classify either head position or movement direction from EMG features offline. Position classification significantly outperformed direction classification, with a mean accuracy of 82.5% ± 0.010 across participants. Performance was consistent when controlling one, two, or all three neck degrees of freedom. A subset of participants with sufficient residual motor function also completed neck movements while talking or chewing. Classification accuracy decreased during talking and chewing, although these effects were not statistically significant. Importantly however, training CNNs with diverse data that included periods of talking and chewing improved algorithm robustness across all conditions. These findings suggest that neck EMG signals can reliably predict intended head movements in ALS, even in the presence of weak and often confounding muscle activity.

Younger ALS caregivers appear to have distinct experiences and needs, yet age- or life-stage variations and processes of caregiving are seldom considered in studies of ALS family caregiver experience. We undertook a qualitative study, guided by constructivist grounded theory methodology, to explore the dynamics of family caregiving following an ALS diagnosis in a younger middle-aged family member (≤55 years). Data were coded to identify psychosocial processes, including how family caregivers engage in caregiving. In-depth interviews were conducted with ten spousal caregivers between August 2023 and August 2025. Overall, our theoretical understanding of spousal caregiving for younger middle-aged adults with ALS (YMAs) was captured by the core category 'straddling two worlds,' reflecting how caregivers navigated multiple interconnected dichotomies: present and future, familiar and new norms, current and anticipated losses, and the worlds of the living and the dying. To contend with an uncertain future, caregivers anchored themselves in the present as they navigated a shifting sense of normalcy. Middle age expectations and social norms shaped how caregivers engaged in caregiving and experienced losses that were often unending and ambiguous. Caregiving for a spouse with ALS in younger middle age involves temporal, practical, emotional, and existential processes.

Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43. Our results demonstrate that depletion of FMRP causes nuclear translocation of TDP-43, reducing cytoplasmic TNKS/TDP-43 co-localization, thereby releasing TNKS in the cytoplasm. Free TNKS gets associated with proteasome inhibitor of 31 kDa (PI31), reversing PI31-mediated inhibition of proteasome assembly, trafficking, and activity. Thus, FMRP regulates proteasome activity by modulating the subcellular distribution of TDP-43. Interestingly, FMRP expression is elevated in specific brain regions and spinal cords of TDP-43A315T transgenic ALS mice that helps more TDP-43 to stay in cytoplasm to sequester more TNKS with it, resulting in proteasome dysfunction in ALS disease system. We have demonstrated for the first time that FMRP can act as a disease modifier for ALS. ALS patients with high FMRP expression in the brain and spinal cord may exhibit more severe protein aggregation due to proteasome dysfunction."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response.","status":"PASS","error":"","abstract_text":"ID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology.

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype × treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current.

This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis.","status":"PASS","error":"","abstract_text":"ID: 42373582\nTitle: Unravelling the Significance of Cystatin C and Bunina Bodies in Amyotrophic Lateral Sclerosis Pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a fatal neurodegenerative disease primarily affecting motor neurons. Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential.

Complementary and alternative medicine (CAM) approaches are widely used by patients with ALS. However, their efficacy remains controversial owing to limited clinical evidence and methodological limitations.

The involvement of gut microbiome dysbiosis in the pathophysiology of ALS has provided a unifying biological framework linking the peripheral, metabolic, and neuroinflammatory processes. These findings suggest that the combination of CAM and conventional therapy may serve as a potential integrative approach to target gut-brain-muscle interactions and systemic disease pathways.

We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input.

The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43.

These preliminary offline analyses investigate neck electromyography (EMG) as an alternative control modality from ALS patients. EMG signals were recorded from four male participants with ALS while performing neck flexion/extension, axial rotation, and lateral deviation. The resulting dataset was used to train convolutional neural networks (CNNs) per patient to classify either head position or movement direction from EMG features offline. Position classification significantly outperformed direction classification, with a mean accuracy of 82.5% ± 0.010 across participants. Performance was consistent when controlling one, two, or all three neck degrees of freedom. A subset of participants with sufficient residual motor function also completed neck movements while talking or chewing. Classification accuracy decreased during talking and chewing, although these effects were not statistically significant. Importantly however, training CNNs with diverse data that included periods of talking and chewing improved algorithm robustness across all conditions.

Younger ALS caregivers appear to have distinct experiences and needs, yet age- or life-stage variations and processes of caregiving are seldom considered in studies of ALS family caregiver experience. We undertook a qualitative study, guided by constructivist grounded theory methodology, to explore the dynamics of family caregiving following an ALS diagnosis in a younger middle-aged family member (≤55 years).

Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43. Our results demonstrate that depletion of FMRP causes nuclear translocation of TDP-43, reducing cytoplasmic TNKS/TDP-43 co-localization, thereby releasing TNKS in the cytoplasm. Free TNKS gets associated with proteasome inhibitor of 31 kDa (PI31), reversing PI31-mediated inhibition of proteasome assembly, trafficking, and activity. Thus, FMRP regulates proteasome activity by modulating the subcellular distribution of TDP-43. Interestingly, FMRP expression is elevated in specific brain regions and spinal cords of TDP-43A315T transgenic ALS mice that helps more TDP-43 to stay in cytoplasm to sequester more TNKS with it, resulting in proteasome dysfunction in ALS disease system.

However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response.

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype × treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current.

Voxel-Based-Morphometry measured GM and White-Matter (WM) density and Surface-Based-Morphometry assessed Cortical Thickness (CT). Non-parametric Threshold-Free-Cluster-Enhancement with 5000 permutations was applied for inter-group and regression contrasts, whilst correcting for possibly interfering co-variates and applying Family-Wise-Error-adjustment. Compared with HC, the ALS cohort showed widespread decreases of CT and GM/WM density (p < 0.001). These case-control effects were driven by patients scanned during rD50-defined disease Phase 2 (p < 0.001). Within the ALS-cohort, direct Phase 2 versus Phase 1 contrasts revealed spatially-distributed decreases, reflecting higher disease accumulation (p < 0.05). These were independent of disease aggressiveness (and onset-region), as corrected for in the models. Accordingly, all contrasts assessing aggressiveness did not yield significant results. These semi-automated analyses of T1-weighted-images captured disease accumulation related GM structural integrity-loss in this cohort scanned with 3-Tesla MRI, independent of the underlying disease aggressiveness. This principle was validated across different scanners and field strengths, supporting its application for objective and non-invasive staging of patients with ALS, whereby true longitudinal studies are necessary."},{"quadrant":"Run1_Eval1_synthesis","attempt":2,"quote":"We propose the Impedance Mismatch Theory, a theoretical biophysical model and quantitative framework for the thermodynamic limits of neural computation, positing that these distinct pathologies converge as a shared energetic stress pathway.","status":"PASS","error":"","abstract_text":"ID: 42364760\nTitle: The impedance mismatch theory: A non-equilibrium thermodynamic framework for a shared energetic stress pathway in neurodegeneration.\nAbstract: Current neurobiological models of Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's Disease (HD) utilize multi-omic interactome analyses to map cascades of proteinopathy. While essential, these approaches often overlook the macroscopic thermodynamic limits of the neural substrate as an information processing system. We propose the Impedance Mismatch Theory, a theoretical biophysical model and quantitative framework for the thermodynamic limits of neural computation, positing that these distinct pathologies converge as a shared energetic stress pathway. We introduce the Neurophysiological Load Index (NLI)-a dimensionless parameter quantifying the mismatch between electrical computational drive, topological network impedance, and the local structural and microvascular dissipation capacity. Drawing on the Pennes Bioheat Transfer Equation and insights from multiplex network theory, we hypothesize that pathology initiates as localized thermal runaway, where resistive metabolic heat exceeds convective blood perfusion and thermal conduction, inducing acute decompensation. We outline cross-translational disease-network mechanisms, address the inverse cancer comorbidity paradox via speculative bioelectric attractor states, and propose falsifiable predictions involving high-resolution in vivo proton magnetic resonance spectroscopy thermometry (1H-MRS-t) and phosphorus-31 magnetic resonance spectroscopy (31P-MRS)."},{"quadrant":"Run1_Eval1_synthesis","attempt":2,"quote":"Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS.","status":"PASS","error":"","abstract_text":"ID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS.

Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential. A deeper understanding of cystatin C biology, its relationship with TDP43 pathology and improved ALS models will be essential for determining whether targeting cystatin C could provide a viable avenue for future ALS therapies."}],"assistantLogs":[{"query":"Answer in English only.

Recent advancements categorize progress in genetic etiology, diagnostic biomarker development, biophysical modeling of neural energetic stress, and novel therapeutic modalities, including gene silencing and peptide-based neuroprotection.\n\n### [INTRODUCTION & JUSTIFICATION]\nResearch into ALS has transitioned from purely neuron-centric views to acknowledging the broader systemic nature of the pathology. \"the success rate of developing drugs for neurological disorders is significantly low.\" Consequently, identifying reliable biomarkers and disease-modifying mechanisms is paramount. \"the blood-brain barrier (BBB) emerges as one of the key challenges in the development and application of drugs against neurological disorders.\" Current efforts are integrating high-resolution imaging and sophisticated genetic screening to provide earlier, more accurate staging. \"Simulated disease trajectories of MUNE values derived from CMAP scans in muscles affected by ALS indicated that MUNE may reach 50% of its maximum in approximately 60% of the time compared to functional impairment.\" Furthermore, new models for monitoring suggest that neurofilament light chain (NfL) concentrations show significant promise as a prognostic tool. \"Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival.\" Emerging theories, such as the Impedance Mismatch Theory, frame the disease within a thermodynamic context, potentially unifying the diverse pathways identified in clinical and preclinical models.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Genetic Stratification:** Large-scale genomic surveys, such as those in Indian cohorts, have identified novel associations like JAK2, indicating neuroinflammatory mechanisms that differ from those in European cohorts.\n*   **Bunina Body Biology:** Cystatin C sequestration into Bunina bodies may represent a critical loss of neuroprotective function, specifically cysteine protease inhibition and autophagy induction.\n*   **Thermodynamic Limits:** Pathogenesis may initiate as localized thermal runaway within the neural substrate, quantifiable via high-resolution spectroscopy.\n*   **Homeostatic Dysfunction:** ALS motoneurons exhibit over-active intrinsic compensatory mechanisms to homeostatic perturbations, indicating that dysfunction is rooted in altered feedback regulation.\n*   **FMRP Proteasome Link:** Fragile X Mental Retardation Protein has been identified as a novel modifier that modulates the subcellular distribution of TDP-43 and subsequent proteasome activity.\n*   **Sensory Nerve Findings:** Sensory nerve conduction abnormalities at diagnosis show a relatively uniform pattern of axonal dysfunction, distinct from the asymmetric, onset-dependent motor involvement.\n*   **Caregiver Burden:** Spousal caregivers of younger middle-aged adults with ALS operate within a 'straddling two worlds' framework, highlighting a need for support that addresses temporal and existential caregiving processes.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Explain this data in simple terms for a non-expert.  List any recent breakthrough discoveries and justify.","finalResponse":"Amyotrophic Lateral Sclerosis (ALS) is increasingly viewed by researchers not just as a condition affecting nerves alone, but as a complex, multisystem disorder [ID: 42411482]. In simple terms, scientists are shifting their focus from looking only at the \"broken\" motor neurons to understanding how the entire body's systems—including metabolism, inflammation, and cellular cleanup—interact to drive the disease [ID: 42411482, 42353064].\n\nHere are the key breakthroughs and findings from the recent data:\n\n1. Novel Genetic Targets: Researchers have identified new genetic players, such as the JAK2 gene in specific populations [ID: 42384233] and the NEK1 kinase [ID: 42351313]. These findings help explain how different people may experience the disease differently, opening doors for more personalized approaches to treatment.\n\n2. A New Way to View Energy Failure: A breakthrough concept called the \"Impedance Mismatch Theory\" suggests that ALS might be caused by a type of \"thermal runaway\" or energetic stress within the brain [ID: 42364760]. This frames the disease as a thermodynamic problem, which could change how we design drugs to protect nerve cells.\n\n3. Improving Cellular Cleanup: Scientists have discovered that a protein called FMRP helps regulate how cells clear out damaged proteins [ID: 42363684]. Additionally, the way a protein called Cystatin C gets trapped in \"Bunina bodies\" (small structures inside cells) may prevent it from protecting neurons, revealing a potential new point for intervention [ID: 42373582].\n\n4. Better Monitoring and Early Detection: We are getting much better at tracking the disease before symptoms become severe. For example, using specialized MRI scans can help measure how the disease progresses [ID: 42371122], and blood/spinal fluid tests for a marker called NfL are becoming powerful tools for predicting how a patient might do over time [ID: 42434198].\n\n5. Gene-Silencing Therapy: In laboratory models, a single injection of a gene-silencing treatment was able to suppress the toxic SOD1 protein, which helped preserve nerve connections and improved muscle function [ID: 42350385].\n\nWhile these discoveries are promising, drug development for neurological conditions remains difficult due to the blood-brain barrier—a protective shield that is hard for many medicines to cross [ID: 42432671].","memoryMode":"dolphin","contextLength":20973,"historyLength":2160,"fullPrompt":"> **SEMANTIC DRIFT IS DISABLED (STRICT MODE):** > **RAG AMNESIA IS ACTIVE:** You must rely **exclusively** on the provided context. >  > **THE ZERO-TOLERANCE GATE:** > 1.

Recent advancements categorize progress in genetic etiology, diagnostic biomarker development, biophysical modeling of neural energetic stress, and novel therapeutic modalities, including gene silencing and peptide-based neuroprotection.\n\n### [INTRODUCTION & JUSTIFICATION]\nResearch into ALS has transitioned from purely neuron-centric views to acknowledging the broader systemic nature of the pathology. \"the success rate of developing drugs for neurological disorders is significantly low.\" Consequently, identifying reliable biomarkers and disease-modifying mechanisms is paramount. \"the blood-brain barrier (BBB) emerges as one of the key challenges in the development and application of drugs against neurological disorders.\" Current efforts are integrating high-resolution imaging and sophisticated genetic screening to provide earlier, more accurate staging. \"Simulated disease trajectories of MUNE values derived from CMAP scans in muscles affected by ALS indicated that MUNE may reach 50% of its maximum in approximately 60% of the time compared to functional impairment.\" Furthermore, new models for monitoring suggest that neurofilament light chain (NfL) concentrations show significant promise as a prognostic tool. \"Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival.\" Emerging theories, such as the Impedance Mismatch Theory, frame the disease within a thermodynamic context, potentially unifying the diverse pathways identified in clinical and preclinical models.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   **Genetic Stratification:** Large-scale genomic surveys, such as those in Indian cohorts, have identified novel associations like JAK2, indicating neuroinflammatory mechanisms that differ from those in European cohorts.\n*   **Bunina Body Biology:** Cystatin C sequestration into Bunina bodies may represent a critical loss of neuroprotective function, specifically cysteine protease inhibition and autophagy induction.\n*   **Thermodynamic Limits:** Pathogenesis may initiate as localized thermal runaway within the neural substrate, quantifiable via high-resolution spectroscopy.\n*   **Homeostatic Dysfunction:** ALS motoneurons exhibit over-active intrinsic compensatory mechanisms to homeostatic perturbations, indicating that dysfunction is rooted in altered feedback regulation.\n*   **FMRP Proteasome Link:** Fragile X Mental Retardation Protein has been identified as a novel modifier that modulates the subcellular distribution of TDP-43 and subsequent proteasome activity.\n*   **Sensory Nerve Findings:** Sensory nerve conduction abnormalities at diagnosis show a relatively uniform pattern of axonal dysfunction, distinct from the asymmetric, onset-dependent motor involvement.\n*   **Caregiver Burden:** Spousal caregivers of younger middle-aged adults with ALS operate within a 'straddling two worlds' framework, highlighting a need for support that addresses temporal and existential caregiving processes.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Perturbed mtDNA maintenance and RNA metabolism have been implicated in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). Here we show that the common TOP1MT variant rs2293925 (R525W) has enhancer-like activity and is associated with increased mitochondrial R-loops (RNA : DNA hybrids). Tissue-dependent expression, quantitative trait locus analysis, chromatin-state annotation, reporter assays, and allele-specific DNA-protein binding assays support a transcriptional regulatory role for rs2293925. In isogenic cell models, rs2293925 increased TOP1MT mRNA and protein abundance, and this was accompanied by increased mitochondrial R-loop signal. TOP1MT trapping with lamellarin D supported increased TOP1MT-R525W occupancy at mitochondrial control region sites together with enhanced R-loops, consistent with altered TOP1MT-mtDNA interaction and/or increased TOP1MT abundance. Elevated mitochondrial R-loop signal was also detected in a pilot cohort of sporadic ALS samples carrying rs2293925 and in neural stem cells derived from C9orf72-positive ALS patients.

Increasing evidence suggests that ALS is a multisystem disorder involving motor neuron degeneration, immune dysregulation, skeletal muscle pathology, and gastrointestinal dysfunction, thereby challenging the adequacy of current therapeutic strategies. Complementary and alternative medicine (CAM) approaches are widely used by patients with ALS. However, their efficacy remains controversial owing to limited clinical evidence and methodological limitations. The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease. The involvement of gut microbiome dysbiosis in the pathophysiology of ALS has provided a unifying biological framework linking the peripheral, metabolic, and neuroinflammatory processes. These findings suggest that the combination of CAM and conventional therapy may serve as a potential integrative approach to target gut-brain-muscle interactions and systemic disease pathways. This article highlights critical gaps in the existing evidence and proposes that microbiome-focused, biomarker-driven clinical trials are essential to thoroughly evaluate CAM-based interventions in ALS.

We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders."},{"quote":"Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis.","source_id":"42397462","status":"PASS","error":"","abstract_text":"ID: 42397462\nTitle: A case study of comprehensive association analysis and risk prediction of amyotrophic lateral sclerosis in a Chinese population.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease with significant genetic heterogeneity.

To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis.

We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (< 30 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR = 3.5 × 10-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency.

The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS."},{"quote":"Simulated disease trajectories of MUNE values derived from CMAP scans in muscles affected by ALS indicated that MUNE may reach 50% of its maximum in approximately 60% of the time compared to functional impairment.","source_id":"42434198","status":"PASS","error":"","abstract_text":"ID: 42434198\nTitle: Quantifying motor unit loss prior to functional impairment in muscles affected by amyotrophic lateral sclerosis.\nAbstract: The compound muscle action potential (CMAP) scan is a non-invasive method for deriving motor unit number estimates (MUNE) to track disease progression in muscles affected by amyotrophic lateral sclerosis (ALS). It remains to be established whether and how long motor unit loss precedes functional impairment. In 56 patients with ALS, we compared the longitudinal trajectories of MUNE derived from thenar CMAP scans, and fine motor function (FMF) using a functional rating scale. Linear and sigmoidal disease trajectories were modelled from which time differences were estimated between these measures to reach their half-maximum scores. The normalized linear decline per month was 0.02 (95% CI 0.01 to 0.03) for FMF and 0.03 (95% CI 0.03 to 0.04) for MUNE. Half-maximum of FMF was reached after 26.3 months (95% CI 18.9 to 35.1) for the linear model, while MUNE had a shorter time required to reach 50% of its maximum with 13.0 months (95% CI 10.3 to 16.4).

The Utah Neck Exoskeleton can restore neck motion, but current control methods-joystick and gaze tracking-have limited accessibility and reliability. These preliminary offline analyses investigate neck electromyography (EMG) as an alternative control modality from ALS patients. EMG signals were recorded from four male participants with ALS while performing neck flexion/extension, axial rotation, and lateral deviation. The resulting dataset was used to train convolutional neural networks (CNNs) per patient to classify either head position or movement direction from EMG features offline. Position classification significantly outperformed direction classification, with a mean accuracy of 82.5% ± 0.010 across participants. Performance was consistent when controlling one, two, or all three neck degrees of freedom. A subset of participants with sufficient residual motor function also completed neck movements while talking or chewing. Classification accuracy decreased during talking and chewing, although these effects were not statistically significant. Importantly however, training CNNs with diverse data that included periods of talking and chewing improved algorithm robustness across all conditions. These findings suggest that neck EMG signals can reliably predict intended head movements in ALS, even in the presence of weak and often confounding muscle activity. Offline accuracy and real-time computational speed suggest the approach is feasible for future online user-in-the-loop studies.

Spouses often assume the role of primary caregiver, facing daily challenges as their partner's needs progressively increase. Younger ALS caregivers appear to have distinct experiences and needs, yet age- or life-stage variations and processes of caregiving are seldom considered in studies of ALS family caregiver experience. We undertook a qualitative study, guided by constructivist grounded theory methodology, to explore the dynamics of family caregiving following an ALS diagnosis in a younger middle-aged family member (≤55 years). Data were coded to identify psychosocial processes, including how family caregivers engage in caregiving. In-depth interviews were conducted with ten spousal caregivers between August 2023 and August 2025. Overall, our theoretical understanding of spousal caregiving for younger middle-aged adults with ALS (YMAs) was captured by the core category 'straddling two worlds,' reflecting how caregivers navigated multiple interconnected dichotomies: present and future, familiar and new norms, current and anticipated losses, and the worlds of the living and the dying. To contend with an uncertain future, caregivers anchored themselves in the present as they navigated a shifting sense of normalcy. Middle age expectations and social norms shaped how caregivers engaged in caregiving and experienced losses that were often unending and ambiguous. Caregiving for a spouse with ALS in younger middle age involves temporal, practical, emotional, and existential processes. Caregivers of YMAs may benefit from interventions that help them tolerate uncertainty, stay grounded in the present, maintain normalcy, and grieve losses throughout the caregiving trajectory."},{"quote":"Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43.","source_id":"42363684","status":"PASS","error":"","abstract_text":"ID: 42363684\nTitle: FMRP-Mediated Proteasome Regulation: A Novel Mechanism in ALS Pathology.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a rare and fatal neurodegenerative disease characterized by the hallmark cytoplasmic accumulation and aggregation of TAR DNA binding protein 43 (TDP-43), which impairs proteasome activity through its interaction with Tankyrase (TNKS). Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43. Our results demonstrate that depletion of FMRP causes nuclear translocation of TDP-43, reducing cytoplasmic TNKS/TDP-43 co-localization, thereby releasing TNKS in the cytoplasm. Free TNKS gets associated with proteasome inhibitor of 31 kDa (PI31), reversing PI31-mediated inhibition of proteasome assembly, trafficking, and activity. Thus, FMRP regulates proteasome activity by modulating the subcellular distribution of TDP-43. Interestingly, FMRP expression is elevated in specific brain regions and spinal cords of TDP-43A315T transgenic ALS mice that helps more TDP-43 to stay in cytoplasm to sequester more TNKS with it, resulting in proteasome dysfunction in ALS disease system. We have demonstrated for the first time that FMRP can act as a disease modifier for ALS. ALS patients with high FMRP expression in the brain and spinal cord may exhibit more severe protein aggregation due to proteasome dysfunction."},{"quote":"DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response.","source_id":"42362484","status":"PASS","error":"","abstract_text":"ID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target."},{"quote":"Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms.","source_id":"42353250","status":"PASS","error":"","abstract_text":"ID: 42353250\nTitle: Microglial Dysfunction Induced by C9ORF72 Dipeptide Repeat Proteins: Biomarker and Therapeutic Perspectives.\nAbstract: The GGGGCC hexanucleotide repeat expansion (HRE) in C9ORF72 was recognized as the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown.

Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype × treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability."},{"quote":"A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved α-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function.","source_id":"42350385","status":"PASS","error":"","abstract_text":"ID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved α-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival.

The D50 disease progression model is a framework to comprehensively dissect biomarker-signals towards their relevance regarding disease accumulation/phase (rD50), or disease aggressiveness (D50). Based on previous findings using 1.5-Tesla Magnetic-Resonance-Imaging (MRI), this study hypothesized that high-resolution MRI markers of Grey-Matter (GM) structural integrity would enable quantification of disease accumulation, independent of aggressiveness. A separate cohort of 75 patients with ALS and 73 Healthy Controls (HC) underwent T1-weighted 3-Tesla MRI. Voxel-Based-Morphometry measured GM and White-Matter (WM) density and Surface-Based-Morphometry assessed Cortical Thickness (CT). Non-parametric Threshold-Free-Cluster-Enhancement with 5000 permutations was applied for inter-group and regression contrasts, whilst correcting for possibly interfering co-variates and applying Family-Wise-Error-adjustment. Compared with HC, the ALS cohort showed widespread decreases of CT and GM/WM density (p < 0.001). These case-control effects were driven by patients scanned during rD50-defined disease Phase 2 (p < 0.001). Within the ALS-cohort, direct Phase 2 versus Phase 1 contrasts revealed spatially-distributed decreases, reflecting higher disease accumulation (p < 0.05). These were independent of disease aggressiveness (and onset-region), as corrected for in the models. Accordingly, all contrasts assessing aggressiveness did not yield significant results.

NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons.

Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology.

Alzheimer's disease (AD), Multiple Sclerosis (MS), Parkinson's disease (PD), Huntington's disease (HD), and Amyotrophic Lateral Sclerosis (ALS) are some of the well-known neurodegenerative diseases that affect millions of people worldwide. Despite the advanced technologies and nano-drug delivery systems, the success rate of developing drugs for neurological disorders is significantly low. Among several constraints, including gastrointestinal irritation, rapid metabolism, and low stability, the blood-brain barrier (BBB) emerges as one of the key challenges in the development and application of drugs against neurological disorders. These challenges necessitate innovative approaches to develop cost-effective therapeutic strategies. Drug repurposing, the discovery of new therapeutic benefits of existing drugs, is a promising drug discovery approach for discovering potential treatment options for complex neurological disorders. This review aims to explore the advanced and significant progress in drug repurposing for major neurological disorders, including MS, AD, PD, ALS, HD, stroke, and neuropsychiatric conditions. It places an explicit emphasis on discussing the potential role of artificial intelligence (AI)-assisted drug repurposing and understanding of the biological mechanisms in discovering new drugs for these neurological conditions. This also examines current challenges in drug repurposing and provides a critical review of the available opportunities and limitations in AI-assisted drug repurposing.\n\nID: 42432439\nTitle: \"An Injurious and Utterly Unfit Environment\": A Case Study Comparing Dental Evidence of Childhood Stress in Nineteenth Century Working-Class Peoples From British and Colonial New Zealand Contexts.\nAbstract: During the nineteenth century, the health and living conditions of many working-class European peoples declined in association with growing industrialization and urbanization. Emigration to British colonies grew as people sought to escape such hardships. This research presents the first direct comparison of dental markers of stress in a case study of migrants to a British colony (Otago, New Zealand) alongside a contemporaneous assemblage representing an origin population (London, United Kingdom). Dental markers of childhood stress, accentuated lines, were observed in thin-sections of archeological teeth from adults (n = 9) and children (n = 16) interred in London, United Kingdom (UK), and adult European migrants interred in Otago, New Zealand (NZ) (n = 24) using standard histological techniques. All individuals interred in London, and 92% (22/24) of those in New Zealand exhibited evidence of accentuated line formation within the first 2.5 years of life. There was no difference in median accentuated line occurrence between adults and children interred in the UK. However, NZ adults had a lower median occurrence of accentuated lines over the first 2.5 years since birth (5 ALs/individual) than UK adults (13 ALs/individual). Accentuated lines most frequently occurred in infancy for all three groups examined. However, temporal trends in accentuated line occurrence differed between groups in association with age. These results highlight the impact of childhood stresses on working-class people growing up during the nineteenth century, underlining potential differences in the childhood experiences of hardship in individuals that remained in Britain and those that departed for foreign soils.\n\nID: 42429841\nTitle: Re: Effects of resistance training with/without photobiomodulation on muscle and respiratory function in difficult-to-control asthma: a randomized trial.\nAbstract: This letter discusses Costa et al.'s randomized trial of resistance training (RT) combined with photobiomodulation therapy (PBMT) for difficult-to-control asthma (DTCA). The triple-blind study shows RT+PBMT safely improves peripheral muscle strength and exercise capacity better than RT alone. PBMT has dose-dependent effects, but optimal parameters for chronic respiratory patients remain unclear. Some clinicians have proposed standalone PBMT for DTCA patients unable to complete resistance training, but this approach has not been validated in clinical trials. The absence of a PBMT-only group limits assessment for patients unable to tolerate RT. The intervention did not improve lung function or asthma control, acting only peripherally. RT+PBMT is a useful adjuvant therapy; future studies should optimize PBMT dosing, test standalone PBMT, and examine long-term outcomes, and compare different PBMT wavelengths, energy settings and irradiation sites to refine real-world treatment protocols.\n\nID: 42428455\nTitle: Laparoscopic temporary uterine artery occlusion combined with en bloc lesion resection for type III cesarean scar pregnancy: surgical technique.\nAbstract: This article presents a refined laparoscopic surgical technique for the management of type IIIb cesarean scar pregnancy (CSP), as classified by Ban et al.'s 2023 criteria [residual myometrial thickness <3 mm, maximum sac diameter (MSD) ≥3 cm, bladder protrusion], in a 35-year-old female with vaginal bleeding and a history of two cesarean sections. The core protocol integrates temporary bilateral uterine artery occlusion (simple ligation of the main trunk with No. 1 absorbable Vicryl suture at 2 cm from the uterine wall) immediately before resection, adhesiolysis, en bloc excision of the ectopic mass with a 0.3 cm safe margin, and multilayer anatomical uterine repair. This technique addresses the key clinical challenge of massive intraoperative bleeding in highly vascular type IIIb CSP, with innovations in precise timing of occlusion and reversible minimally invasive ligation. Perioperative outcomes demonstrated excellent hemostasis (total blood loss 100 mL), complete lesion removal confirmed by frozen section, and intact uterine anatomy post-surgery. The study emphasizes the technique's value in hemorrhage control, anatomical restoration, and fertility preservation for patients with large type IIIb CSP (66 mm in this case). We provide a detailed step-by-step surgical guide, clarify patient selection criteria and contraindications, and discuss the technique's advantages, limitations, and potential to revise the standard of care for type III CSP. Postoperative 18-month follow-up showed successful natural conception and uncomplicated second-trimester pregnancy, validating its long-term fertility benefits.\n\nID: 42426879\nTitle: Evaluating the impact of implementing an ECPR protocol on prehospital resuscitation quality: a randomized controlled simulation study.\nAbstract: Extracorporeal Cardiopulmonary Resuscitation (ECPR) is increasingly considered for prehospital cardiac arrest management; however, its impact on resuscitation performance remains unclear. This study aimed to determine whether integrating an ECPR protocol into prehospital cardiac arrest care affects the quality of resuscitation compared to application of the standard Advanced Life Support (ALS) protocol. A randomized controlled simulation study was conducted at the University Hospital Leuven in Belgium using standardized pre-hospital cardiac arrest scenarios. Participants, who were physicians functioning as part of resuscitation teams, were randomized into intervention and control groups. The study included a pre- and post-intervention phase. In the pre-phase, all participants followed the standard ALS protocol. Only the intervention group received training in the additional ECPR protocol between the phases. In the post-phase, the intervention group combined this protocol with standard ALS, whereas the control group continued with ALS alone. The primary outcome was overall resuscitation quality, which was assessed using the modified Peltonen score. The secondary outcomes included occurrence and timing of critical resuscitation actions. A total of 40 physicians participated in the study. Resuscitation quality was not affected by the ECPR protocol; the modified Peltonen score showed no difference in the pre-post change between the groups (0.02, CI: -0.15; 0.19, p = 0.83). However, secondary outcomes showed delayed actions related to the identification and management of the presumed cause of cardiac arrest in the intervention group, such as significantly later verbal suggestions to initiate causal treatments including PCI or thrombolysis. In this simulation study, combining a prehospital ECPR protocol with standard ALS resulted in resuscitation performance comparable to ALS alone. Nonetheless, the protocol was associated with delayed diagnostic and therapeutic actions concerning the reversible causes of cardiac arrest, highlighting the need for ECPR training that integrates diagnostic and therapeutic vigilance with procedural execution.

Yet there is limited guidance on how comprehensive care should be achieved and implemented. We present global consensus recommendations for comprehensive care of patients with MG. An international panel of experts was formed, and a targeted literature review was conducted to inform the recommendations. A steering committee selected relevant topics and draft recommendations were developed for each topic. Formal consensus was achieved using the RAND/UCLA appropriateness method. Seventeen panelists from North America, Europe, and Asia rated statements online from 1 (\"extremely inappropriate\") to 9 (\"extremely appropriate\") and provided comments and suggestions for modifications. The methodologist modified statements for further rating, based on panel scores and feedback. Statements achieving agreement as appropriate by 4 rounds of rating were accepted. Consensus was achieved for 21 statements. Statement 1 defined the ongoing treatment goal: \"to work toward, achieve, and sustain minimal symptoms and treatment-related adverse events, with a patient-acceptable quality of life (using validated measures)\". Subsequent statements described implementation of this goal and covered: early control of symptoms; establishing and sustaining a treatment goal; vaccination and screening for infection; family planning/pregnancy; management of fatigue and comorbidities; and management of impending crisis and crisis. Expert consensus was achieved on a series of global recommendations for comprehensive care goals, which has implications for improved disease outcomes and health-related quality of life for patients with MG. These recommendations will require updating as treatment paradigms evolve.\n\nID: 42420060\nTitle: Development of a target product profile for artificial intelligence in diabetic eye screening in England: a modified Delphi consensus study.\nAbstract: Artificial intelligence (AI) health-care technologies offer a means of addressing the growing gap between health-care capacity and demand. However, few technologies have met the complex requirements of health-care systems for adoption. Diabetic eye screening (DES) in England exemplifies the difficulty of understanding these requirements and translating them into real-world implementation decisions. This Review responds to a recognised policy need to develop a target product profile (TPP) for a DES AI system for use in England. The TPP outlines the requirements of the English health-care system for such a device and was developed using a modified Delphi consensus process involving interviews, surveys, and a consensus meeting. Participants included people living with diabetes, health-care professionals, health-care managers and leaders, regulators and policy makers, and developers. Thirty-five product specifications were agreed upon, covering areas such as clinical validity, utility, and environmental sustainability. Our TPP establishes clear criteria for DES AI development and deployment in England, and this TPP development process can serve as a template for initiatives to create TPPs for other AI health technologies and settings.\n\nID: 42419740\nTitle: TOP1MT rs2293925 is an enhancer-active regulatory SNP that shapes mitochondrial R-loop dynamics.\nAbstract: Mitochondrial topoisomerase 1 (TOP1MT) regulates mitochondrial DNA (mtDNA) topology during transcription and replication. Perturbed mtDNA maintenance and RNA metabolism have been implicated in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). Here we show that the common TOP1MT variant rs2293925 (R525W) has enhancer-like activity and is associated with increased mitochondrial R-loops (RNA : DNA hybrids). Tissue-dependent expression, quantitative trait locus analysis, chromatin-state annotation, reporter assays, and allele-specific DNA-protein binding assays support a transcriptional regulatory role for rs2293925. In isogenic cell models, rs2293925 increased TOP1MT mRNA and protein abundance, and this was accompanied by increased mitochondrial R-loop signal. TOP1MT trapping with lamellarin D supported increased TOP1MT-R525W occupancy at mitochondrial control region sites together with enhanced R-loops, consistent with altered TOP1MT-mtDNA interaction and/or increased TOP1MT abundance. Elevated mitochondrial R-loop signal was also detected in a pilot cohort of sporadic ALS samples carrying rs2293925 and in neural stem cells derived from C9orf72-positive ALS patients. These data support a dual-effect model in which rs2293925 increases TOP1MT expression and is associated with altered mitochondrial R-loop dynamics, linking common genetic variation to mitochondrial nucleic acid stress in disease-relevant contexts.\n\nID: 42418280\nTitle: Phase Separation Drives Pathological Aggregation in Neurodegenerative Diseases: A 15-Year Bibliometric Landscape (2009-2024).\nAbstract: Liquid-liquid phase separation (LLPS), a biophysical driver of membraneless organelle assembly, is central to pathological aggregation in neurodegenerative diseases. Initially linked to amyotrophic lateral sclerosis (ALS), LLPS dysregulation has now been implicated in Alzheimer's, Parkinson's, and frontotemporal dementia, where aberrant transitions convert dynamic condensates into insoluble fibrils. To systematically map this landscape, we employed CiteSpace-based bibliometrics to analyze 784 Web of Science articles from 2009 to 2024. Our analyses reveal dominant contributions from the United States, China, and Germany, with collaborative networks focusing on protein dynamics. Key hotspots include LLPS-driven aggregation of TARDBP (TDP-43), FUS, and α-synuclein, alongside stress granule dysfunction and nucleocytoplasmic transport defects. Emerging frontiers highlight therapeutic strategies targeting pathological condensates utilizing small-molecule chaperones and posttranslational modification modulators to restore cellular homeostasis. Our findings underscore LLPS as a critical axis bridging molecular pathology and translational innovation. The field is rapidly shifting from mechanistic exploration to therapeutic applications, emphasizing interventions to halt or reverse aggregation. By delineating global trends and changing priorities, our study highlights the transformative potential of phase-targeted interventions and provides a roadmap of groundbreaking interdisciplinary research into neurodegenerative disorders.\n\nID: 42430680\nTitle: Neurology® Journal Club: Duration of Current Statin Use and Amyotrophic Lateral Sclerosis Risk.\nAbstract: This article critically appraises the study by Nakken et al., \"Duration of Current Statin Use and Amyotrophic Lateral Sclerosis (ALS) Risk.\" Previous observational studies and Mendelian randomization studies examining statin use and ALS risk have reported mixed results. Millions of adults receive statins for cardiovascular prevention and may be concerned when neuromuscular symptoms suggestive of ALS appear. Using linked nationwide health survey and prescription data, this Norwegian population-based cohort study applied time-dependent models to evaluate statin use and subsequent ALS risk. Short-term statin use was associated with increased ALS risk, whereas long-term use was associated with lower risk. The authors interpreted this as evidence of reverse causation rather than a causal or protective effect of statins. Key strengths of the study include its large population-based design, the use of a negative control, and time-dependent Cox modeling. However, limitations inherent to observational study designs and potential residual confounding should be considered. In this article, we summarize the findings, highlight key statistical concepts, and discuss the study's major strengths and limitations.\n\nID: 42425598\nTitle: Unusual presentation of amyotrophic lateral sclerosis years after a motor-vehicle collision.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare disease caused by the destruction of motor neurons, typically presenting with unilateral lower motor neuron and upper motor neuron symptoms. Here, we report the case of a female in her mid-60s with a complex history of lower extremity weakness following a motor-vehicle collision 3 years before her current presentation with a subacute complaint of right-sided leg weakness. With an atypical symptom course consisting of resolved and recurrent weakness of her left leg, the patient had multi-level chronic, evolving spinal-column damage, severe weight loss, newly discovered rectal neoplasm and longstanding psychiatric pathology. With symptoms concerning for both medical and psychosomatic explanations, several potentially compounded aetiologies were considered. Here, we discuss important considerations for fluctuating chronic and subacute neurological complaints with a broad differential diagnostic spectrum and how a macro-perspective of symptoms over years can aid in the diagnosis of a challenging ALS presentation.\n\nID: 42414029\nTitle: Case of concurrent ALS and human T-cell leukaemia virus type 1-associated myositis.\nAbstract: A woman in her late 70s presented with progressive limb weakness, muscle atrophy and hyper-reflexia. Laboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody. Clinical and electrophysiological findings met revised El Escorial criteria for amyotrophic lateral sclerosis (ALS), but muscle MRI showed inflammatory changes. Muscle biopsy revealed both neurogenic and inflammatory features. While methylprednisolone showed no benefit, intravenous immunoglobulin therapy produced transient improvement in weakness with normalisation of creatine kinase levels. The patient died from respiratory failure 3 years after symptom onset. Autopsy confirmed typical ALS-TDP pathology with phosphorylated TDP-43 inclusions in motor neurons. HTLV-1 Tax-positive lymphocytes infiltrated skeletal muscles but not the central nervous system, establishing dual pathology of ALS-TDP with HTLV-1-associated myositis. The improvement most likely reflected treatment of the HTLV-1-associated myositis rather than the underlying motor neuron disease. This case highlights the importance of evaluating treatable conditions in HTLV-1-seropositive ALS patients.\n\nID: 42411953\nTitle: Reduced Soluble Ubiquilin2 in Amyotrophic Lateral Sclerosis Carrying Ubiquilin2 (P494L) Mutation: Clinicopathological and Biochemical Evidence From an Autopsy Case.\nAbstract: We report the clinicopathological and biochemical findings of ALS associated with a UBQLN2 P494L mutation. Autopsy revealed widespread TDP-43 pathology and UBQLN2-positive inclusions. Immunoblot analysis demonstrated a marked reduction of soluble UBQLN2, supporting functional UBQLN2 insufficiency as a pathogenic mechanism underlying TDP-43 aggregation.\n\nID: 42411482\nTitle: Amyotrophic Lateral Sclerosis as a Systemic Disease: Why Integrative and Microbiome-Focused Approaches Deserve Re-Evaluation.\nAbstract: Despite decades of intensive research, therapeutic advances in amyotrophic lateral sclerosis (ALS) remain limited. Increasing evidence suggests that ALS is a multisystem disorder involving motor neuron degeneration, immune dysregulation, skeletal muscle pathology, and gastrointestinal dysfunction, thereby challenging the adequacy of current therapeutic strategies. Complementary and alternative medicine (CAM) approaches are widely used by patients with ALS. However, their efficacy remains controversial owing to limited clinical evidence and methodological limitations. The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease. The involvement of gut microbiome dysbiosis in the pathophysiology of ALS has provided a unifying biological framework linking the peripheral, metabolic, and neuroinflammatory processes. These findings suggest that the combination of CAM and conventional therapy may serve as a potential integrative approach to target gut-brain-muscle interactions and systemic disease pathways. This article highlights critical gaps in the existing evidence and proposes that microbiome-focused, biomarker-driven clinical trials are essential to thoroughly evaluate CAM-based interventions in ALS. Embracing a system-oriented therapeutic framework may help address the complexity of ALS beyond traditional neuron-centered approaches.\n\nID: 42407013\nTitle: Role of the Upper Motor Neuron in the Generation of Fasciculations in Early Disease Stages of Amyotrophic Lateral Sclerosis.\nAbstract: The origin of fasciculation potentials (FPs) in the early stages of amyotrophic lateral sclerosis (ALS) remains a subject of debate. We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders.\n\nID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1α pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers α-synuclein accumulation and affects autophagy; both markers of PD. Combining nano‑resveratrol formulations with L‑DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co‑administration with EGCG has shown synergistic neuroprotection in vitro (SH‑SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.\n\nID: 42397462\nTitle: A case study of comprehensive association analysis and risk prediction of amyotrophic lateral sclerosis in a Chinese population.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease with significant genetic heterogeneity. While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients.\n\nID: 42392979\nTitle: Deletion of exon 2 in ALS-linked Sptlc1 causes lethality in homozygous mice but not in heterozygotes.\nAbstract: Mutations in the human SPTLC1 gene have recently been linked to early-onset amyotrophic lateral sclerosis (ALS), characterized by global atrophy, motor impairments, and symptoms such as tongue fasciculations. All known ALS-linked SPTLC1 mutations cluster within exon 2, and a specific variant, c.58G>T, results in exon 2 skipping. However, it is unclear how the exon 2 deletion affects SPTLC1 function in vivo and contributes to ALS pathogenesis. Leveraging the high genomic sequence similarity between mouse and human SPTLC1, we created a novel knock-in mouse model with a CRISPR/Cas9-mediated deletion of exon 2 in the endogenous murine Sptlc1 locus. Although heterozygous mice did not develop motor defects or ALS-like neuropathology, homozygous mutants died prematurely. These findings provide valuable insights into SPTLC1 exon 2 biology and serve as a useful resource for future mechanistic studies.\n\nID: 42386657\nTitle: The SQSTM1 L341V Variant Associated With Sporadic ALS Promotes the Accumulation of Enlarged Ubiquitin-Positive SQSTM1 Bodies.\nAbstract: SQSTM1 is one of the causative genes of neurodegenerative disorders, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The SQSTM1 protein regulates the degradation of polyubiquitinated proteins and autophagosome formation through its interaction with microtubule-associated protein light chain 3 (MAP1LC3/LC3). However, the molecular mechanisms by which SQSTM1-LC3 binding regulates the autophagy-endolysosomal system (APELS) remain unclear. To elucidate the spatiotemporal role of SQSTM1, we transiently expressed wild-type SQSTM1 or missense mutants carrying mutations in the LC3-interacting region (LIR), fused with the photoconvertible fluorescent protein Dendra2. Live-cell fluorescence imaging and co-localization analyses with markers of the APELS were then performed. Particle analysis of photoconverted or non-photoconverted SQSTM1-positive structures in live cells revealed that the pathogenic L341V variant formed larger structures than the wild-type. Co-localization analyses further showed that both the L341V and artificial LIR3A mutants accumulated in large ubiquitin-positive structures, likely due to impaired localization to autophagosomes. These results suggest that mutations within the LIR differentially affect autophagosome formation and cargo degradation within APELS-related compartments, highlighting the importance of SQSTM1 structural integrity in ALS/FTD pathogenesis.\n\nID: 42439916\nTitle: [Cross-linking treatment of ultrathin corneas: the ELZA-sub400 protocol : Individualized adaptation of fluence as paradigm shift in CXL treatment of thin corneal conditions].\nAbstract: The Dresden corneal cross-linking (CXL) protocol requires a minimum corneal thickness of 400 µm to protect the endothelium from UV (ultraviolet) damage; however, many patients with advanced corneal ectatic disease have thinner corneas and are excluded from treatment. Earlier approaches to circumvent this limitation, hypo-osmolar swelling, contact lens-assisted CXL, epithelial island techniques, showed relevant shortcomings. The ELZA-sub400 protocol takes a fundamentally different approach: the UV fluence is individually adapted to pachymetry. This narrative review is based on current literature and clinical experience data from the ELZA Institute. The photochemical principles, the algorithm of the sub400 protocol, clinical outcomes and practical implementation are presented. The sub400 protocol is based on an algorithm integrating Fick's law of diffusion for riboflavin and oxygen and the Lambert-Beer law for UV absorption. By individually adjusting the duration of UV irradiation to the pachymetrically measured stromal thickness, effective cross-linking is achieved while maintaining a 70 µm safety margin above the endothelium. A prospective study of 39 eyes (corneal thickness 214-398 µm) demonstrated a 90% success rate with no signs of endothelial decompensation. The protocol has also been applied in keratoglobus (1 case; tomographic stabilization at 32 months, no endothelial decompensation) [4]. The ELZA-sub400 protocol enables safe CXL even in corneas well below 400 µm thick for the first time. It adapts the technique to the individual anatomy rather than adapting the anatomy to the technique. Implementation requires only ultrasound pachymetry and a 3 mW/cm2 UV light source and is therefore feasible on most available CXL devices. HINTERGRUND: Das korneale Crosslinking (CXL) nach dem Dresden-Protokoll setzt eine minimale Hornhautdicke von 400 µm voraus, um das Endothel vor UV(ultraviolett)-Schäden zu schützen. Viele Patienten mit fortgeschrittener kornealer Ektasie weisen jedoch dünnere Hornhautzustände auf und werden von der Behandlung ausgeschlossen. Frühere Ansätze zur Umgehung dieser Limitation – hypoosmolare Quellung, kontaktlinsengestützte Verfahren – zeigten relevante Einschränkungen. Das ELZA-sub400-Protokoll verfolgt einen grundlegend anderen Ansatz: Die UV-Fluenz wird individuell an die Pachymetrie angepasst. Die Übersichtsarbeit basiert auf aktueller Literatur und aktuellen klinischen Daten des ELZA Institute. Dargestellt werden die photochemischen Grundlagen, der Algorithmus des sub400-Protokolls, klinische Ergebnisse und die praktische Durchführung. Das sub400-Protokoll basiert auf einem Algorithmus, der das Fick-Diffusionsgesetz für Riboflavin und Sauerstoff sowie das Lambert-Beer-Gesetz für die UV-Absorption integriert. Durch individuelle Anpassung der UV-Bestrahlungsdauer an die pachymetrisch gemessene Stromadicke wird ein effektives Crosslinking erzielt und gleichzeitig ein 70-µm-Sicherheitsabstand zum Endothel gewährleistet. In einer ersten prospektiven Studie mit 39 Augen (Hornhautdicke 214–398 µm) und Folgestudien wurde eine Erfolgsrate von 90 % ohne Zeichen einer Endotheldekompensation erreicht. Das Protokoll wurde auch beim Keratoglobus angewandt (1 Fall; tomographische Stabilisierung nach 32 Monaten, keine Endotheldekompensation) [4]. Das ELZA-sub400-Protokoll ermöglicht erstmals ein sicheres CXL auch bei Hornhautzuständen deutlich unter 400 µm. Es passt die Technik an die individuelle Anatomie an, anstatt die Anatomie an die Technik anzupassen. Der Einsatz erfordert lediglich eine Ultraschallpachymetrie und eine 3‑mW/cm2-UV-Lichtquelle und ist damit auf den meisten verfügbaren CXL-Geräten durchführbar.\n\nID: 42436431\nTitle: \"Straddling two worlds\": complexities of spousal caregiving in amyotrophic lateral sclerosis during younger middle age.\nAbstract: Family support is central to amyotrophic lateral sclerosis (ALS) care. Spouses often assume the role of primary caregiver, facing daily challenges as their partner's needs progressively increase. Younger ALS caregivers appear to have distinct experiences and needs, yet age- or life-stage variations and processes of caregiving are seldom considered in studies of ALS family caregiver experience. We undertook a qualitative study, guided by constructivist grounded theory methodology, to explore the dynamics of family caregiving following an ALS diagnosis in a younger middle-aged family member (≤55 years). Data were coded to identify psychosocial processes, including how family caregivers engage in caregiving. In-depth interviews were conducted with ten spousal caregivers between August 2023 and August 2025. Overall, our theoretical understanding of spousal caregiving for younger middle-aged adults with ALS (YMAs) was captured by the core category 'straddling two worlds,' reflecting how caregivers navigated multiple interconnected dichotomies: present and future, familiar and new norms, current and anticipated losses, and the worlds of the living and the dying. To contend with an uncertain future, caregivers anchored themselves in the present as they navigated a shifting sense of normalcy. Middle age expectations and social norms shaped how caregivers engaged in caregiving and experienced losses that were often unending and ambiguous. Caregiving for a spouse with ALS in younger middle age involves temporal, practical, emotional, and existential processes. Caregivers of YMAs may benefit from interventions that help them tolerate uncertainty, stay grounded in the present, maintain normalcy, and grieve losses throughout the caregiving trajectory.\n\nID: 42435104\nTitle: Deterministic selection and compositional turnover in Parkinson's disease-associated gut dysbiosis.\nAbstract: The scientific understanding of links between Parkinson's disease (PD) and gut microbiome dysbiosis has advanced significantly, yet the ecological mechanisms driving these microbial changes remain poorly understood. To address this gap, we postulated that PD-associated gut dysbiosis arises as harmful microbes outcompete beneficial bacteria, and consequently any therapeutic strategies must both suppress opportunistic pathogens and restore protective, fiber-degrading microbes to effectively rebalance the gut microbiome in PD. To evaluate ecological patterns consistent with this hypothesis, we apply Sloan's near-neutral model (SNM), Ning et al.'s stochasticity framework, and ecological network analysis to reanalyze six published gut microbiome datasets (1957 samples total: 804 healthy controls, 1153 PD cases). We first applied SNM to categorize bacterial species as neutral, positively selected, or negatively selected. While the overall proportions of these categories were similar between groups (neutral: ~ 40%, positively selected: ~ 47%, negatively selected: ~ 13%), stochasticity framework analysis revealed significantly stronger deterministic selection in PD microbiomes. Shared species analysis (SSA) resolved this apparent paradox by demonstrating substantial compositional shifts within each species category, indicating that while classification frequencies remained stable, the specific microbes occupying these ecological niches changed significantly in PD. This divergence between SNM category proportions and NSR values highlights a subtle yet critical aspect of community assembly dynamics. Ecological network analysis further revealed that neutral species had fewer antagonistic co-occurrence links, consistent with their ecological equivalence, while negatively selected species maintained higher relative abundances in both groups. Together, these findings indicate that PD-associated gut microbiomes are characterized by stronger deterministic assembly signatures and substantial compositional turnover within near-neutral ecological categories. These patterns are consistent with altered ecological assembly signatures in PD-associated dysbiosis.\n\nID: 42434198\nTitle: Quantifying motor unit loss prior to functional impairment in muscles affected by amyotrophic lateral sclerosis.\nAbstract: The compound muscle action potential (CMAP) scan is a non-invasive method for deriving motor unit number estimates (MUNE) to track disease progression in muscles affected by amyotrophic lateral sclerosis (ALS). It remains to be established whether and how long motor unit loss precedes functional impairment. In 56 patients with ALS, we compared the longitudinal trajectories of MUNE derived from thenar CMAP scans, and fine motor function (FMF) using a functional rating scale. Linear and sigmoidal disease trajectories were modelled from which time differences were estimated between these measures to reach their half-maximum scores. The normalized linear decline per month was 0.02 (95% CI 0.01 to 0.03) for FMF and 0.03 (95% CI 0.03 to 0.04) for MUNE. Half-maximum of FMF was reached after 26.3 months (95% CI 18.9 to 35.1) for the linear model, while MUNE had a shorter time required to reach 50% of its maximum with 13.0 months (95% CI 10.3 to 16.4). The head-to-head comparison between FMF and MUNE showed that MUNE values reached 50% of its maximum 13.1 months (95% CI 7.0-20.8) earlier. Results were similar for sigmoidal disease trajectories. Simulated disease trajectories of MUNE values derived from CMAP scans in muscles affected by ALS indicated that MUNE may reach 50% of its maximum in approximately 60% of the time compared to functional impairment. These explorative findings underscore how neurophysiological measures may be of use for early disease monitoring, with relevance for both care and research settings.\n\nID: 42432946\nTitle: A simulation study on optimizing stationary camera locations for physician-directed telemedical supervision of prehospital advanced life support: Single-versus dual-camera setups.\nAbstract: Prehospital telemedicine, particularly real-time video conferencing, offers significant benefits in prehospital and disaster settings by enabling rapid data transmission. Using a smartphone mounted on a tripod as a stationary camera provides stable footage, comprehensive scene evaluation, and reduced technical complexity, thus complementing smart glasses and built-in cameras. However, the optimal camera location for visualizing key procedures remains unexplored. This study aims to compare the optimal stationary camera location and the effectiveness of single-camera versus dual-camera setups in visualizing key procedures for physician-directed telemedical supervision of prehospital advanced life support (ALS). This prospective, non-randomized simulation study involved 9 advanced emergency medical technicians performing ALS procedures in 20 simulations. Each simulation was recorded simultaneously from 4 stationary camera locations: right head, left head, right leg, and left leg. Reviewers evaluated the visibility of 6 key procedures (airway management, breathing support, chest compressions, intravenous access, electrocardiogram rhythm monitoring, and teamwork) using a 1 to 5 scale. Mixed models and generalized linear mixed models were applied to analyze the visibility scores and compare the effect sizes of the different camera setups. The median visibility scores and proportion of optimal visibility (scores of 4-5) varied significantly across the 4 camera locations for most procedures. However, the mixed model and generalized linear model analyses for overall visibility did not reveal significant differences in effect sizes between individual camera locations. Dual-camera setups showed significant improvement over single-camera setups, with an adjusted odds ratio of 4.89 (95% confidence interval: 1.92-12.4) for the right head + left head combination and 3.74 (95% confidence interval: 1.50-9.32) for the right head + left leg combination. Although no single-camera location provided optimal visualization for all procedures, dual-camera setups were more effective than single cameras in capturing field activity. These findings support the use of dual-camera setups to enhance physician-directed telemedical supervision of prehospital ALS, with potential applicability to disaster settings, and may inform the development of future protocols for prehospital telemedicine.\n\nID: 42432003\nTitle: Compound muscle action potential scan dataset in adults with spinal cord injury and healthy controls.\nAbstract: Certain neurological conditions, such as amyotrophic lateral sclerosis (ALS) and spinal cord injury (SCI), result in motor unit loss in muscles. The stimulus-evoked compound muscle action potential (CMAP) scan captures comprehensive information on motor unit recruitment that enables rapid and non-invasive assessment of motor unit status. However, few publicly available CMAP scan datasets exist to support research on motor unit number estimation (MUNE). To address this gap, we collected CMAP scan data from the first dorsal interosseous (FDI) muscle of 13 individuals with SCI and 13 healthy participants, and established a dedicated CMAP scan dataset. The dataset includes CMAP waveforms evoked by each nerve stimulus from which CMAP scan curve and typical parameters were extracted for direct use. All SCI participants underwent multiple clinical assessments and exhibited a spectrum of impairment severity from mild to severe, resulting in diverse CMAP features. We anticipate that this dataset will facilitate the development of advanced CMAP scan-based assessment techniques and aid in the investigation of neuromuscular impairment.\n\nID: 42431020\nTitle: Clinical studies in 82 individuals with valosin-containing protein (VCP) associated multisystem proteinopathy and literature review.\nAbstract: Valosin-containing protein (VCP) pathogenic variants cause a multisystem proteinopathy characterized by myopathy, Paget disease of bone, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS). We evaluated 82 affected individuals, 14 presymptomatic carriers, and 36 unaffected first-degree relatives from 48 families to identify sensitive measures for disease monitoring. Mean age of onset was ∼42 years for myopathy, Paget disease, or ALS, and 53 years for dementia. Functional assessments included the Inclusion Body Myositis Functional Rating Scale (IBMFRS), ALSFRS-R, Fatigue Severity Scale (FSS), and six-minute walk test (6MWT). Affected individuals demonstrated progressive functional decline, with IBMFRS decreasing 1.9% annually, FSS increasing 4.4%, and 6MWT decreasing 6% annually when modeled against disease duration. Women declined more rapidly on IBMFRS but showed slower ambulatory and fatigue progression. Potential genotype-specific effects were observed, with earlier onset and shorter survival in p.Arg155Cys compared to later onset in p.Arg155His. Strong correlations among IBMFRS, FSS, and 6MWT indicate these as accessible endpoints for longitudinal monitoring and clinical trials. Rapid decline with ALS and dementia necessitates multidisciplinary support, while longer survival after myopathy or Paget onset offers a window for preventive and supportive interventions.\n\nID: 42430317\nTitle: Preliminary Investigation of Myoelectric Control of an Assistive Neck Exoskeleton by Individuals with Amyotrophic Lateral Sclerosis.\nAbstract: Neck weakness limits head control and quality of life for individuals with Amyotrophic Lateral Sclerosis (ALS). The Utah Neck Exoskeleton can restore neck motion, but current control methods-joystick and gaze tracking-have limited accessibility and reliability. These preliminary offline analyses investigate neck electromyography (EMG) as an alternative control modality from ALS patients. EMG signals were recorded from four male participants with ALS while performing neck flexion/extension, axial rotation, and lateral deviation. The resulting dataset was used to train convolutional neural networks (CNNs) per patient to classify either head position or movement direction from EMG features offline. Position classification significantly outperformed direction classification, with a mean accuracy of 82.5% ± 0.010 across participants. Performance was consistent when controlling one, two, or all three neck degrees of freedom. A subset of participants with sufficient residual motor function also completed neck movements while talking or chewing. Classification accuracy decreased during talking and chewing, although these effects were not statistically significant. Importantly however, training CNNs with diverse data that included periods of talking and chewing improved algorithm robustness across all conditions. These findings suggest that neck EMG signals can reliably predict intended head movements in ALS, even in the presence of weak and often confounding muscle activity. Offline accuracy and real-time computational speed suggest the approach is feasible for future online user-in-the-loop studies. Altogether, this pilot work advances EMG-based assistive technology for individuals with severe motor impairments, laying the groundwork for clinically viable, intuitive control systems.\n\nID: 42429951\nTitle: [Choroidal folds as a diagnostic indication for a posterior mass of unknown etiology].\nAbstract: A 59-year-old woman presented with a four-month history of progressive visual loss and floaters in her left eye. Her medical history included hypothyroidism, psoriasis, and type 2 diabetes. Fundus examination revealed choroidal folds, an amelanotic lesion temporal to the fovea, and an exudative retinal detachment. Optical coherence tomography (OCT) demonstrated a choroidal mass without subretinal fluid, while indocyanine green angiography (ICGA) showed a hypocyanescent lesion with no intrinsic vascularity. B-scan ultrasonography revealed an inhomogeneous choroidal mass with retrobulbar fluid (positive T-sign). Blood tests revealed elevated C-reactive protein (CRP) and liver enzymes levels, together with positive antinuclear antibodies (ANA), while the chest X-ray was normal. The overall clinical and imaging findings were consistent with nodular granulomatous scleritis. Choroidal melanoma, uveal lymphoma, primary vitreoretinal lymphoma, and choroidal hemangioma were excluded based on their imaging characteristics. Treatment with systemic corticosteroids resulted in rapid visual improvement and complete resolution of the lesion. This case demonstrates how inflammatory choroidal lesions can mimic intraocular tumors. Recognizing characteristic multimodal imaging features (choroidal folds, preserved choroidal vasculature on ICGA, positive T-sign on ultrasonography) can enable a confident diagnosis without biopsy, avoiding unnecessary treatment and delays in cancer diagnosis. Eine 59-jährige Patientin stellte sich mit seit vier Monaten progredienter Visusminderung und Mouches volantes am linken Auge vor, ohne Augenbewegungsschmerzen oder Gelenkbeschwerden. Anamnestisch bestanden Hypothyreose, Psoriasis und Diabetes mellitus Typ II. Funduskopisch zeigten sich am linken Auge Aderhautfalten, eine amelanotische, temporal der Fovea gelegene Läsion sowie eine exsudative Ablatio retinae. Die optische Kohärenztomographie (OCT) zeigte eine choroidale Raumforderung ohne subretinale Exsudation, die Indocyaningrünangiographie (ICGA) eine hypocyaneszente, gefäßfreie Läsion. Sonographisch fand sich eine inhomogene Raumforderung mit retroskleraler Flüssigkeit (positives T-Zeichen). Laborchemisch bestanden ein erhöhtes C-reaktives Protein (CRP), erhöhte Leberwerte und positive antinukleäre Antikörper (ANA). Der Röntgen-Thorax war unauffällig. Diese Befunde stützten die Verdachtsdiagnose einer nodulären granulomatösen Skleritis. Differentialdiagnostisch wurden Aderhautmelanom, uveales Lymphom, primäres vitreoretinales Lymphom und chorioidales Hämangiom erwogen. Unter Kortisontherapie mit Prednisolon zeigten sich rasche Visusbesserung und vollständige, stabile Rückbildung der Läsion. Der Fall verdeutlicht, dass die Abgrenzung entzündlicher von neoplastischen intraokularen Raumforderungen zu den schwierigsten Situationen der Ophthalmoonkologie zählt und klinische Erfahrung sowie konsequente multimodale Bildgebung erfordert, um Übertherapie und Verzögerungen der Tumordiagnostik zu vermeiden. Das Vorliegen von wichtigen Befunden in der multimodalen Diagnostik (Aderhautfalten, normalen Aderhautgefäßen in der ICGA, T-Zeichen im Ultraschall) können die korrekte nicht-invasive differentialdiagnostische Einordnung ermöglichen.\n\nID: 42429931\nTitle: [Medial patellofemoral ligament duplication and lateral lengthening plasty ('soft tissue balancing') according to Urs W.

Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the α1 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.\n\nID: 42384233\nTitle: Genome-wide spectrum of coding DNA variations in Indian patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited therapies, emphasizing the need for deeper understanding of disease pathogenesis. While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (< 30 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR = 3.5 × 10-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.\n\nID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.\n\nID: 42381488\nTitle: Neural Organoid Models as a Platform for Studying Disease Mechanisms in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder affecting upper and lower motor neurons leading to muscle wasting. However, structural and molecular abnormalities, including cortical thinning and TDP-43 pathology, extend into frontal, parietal, and temporal areas, pointing to defects across broader cortical regions. The advent of human induced pluripotent stem cell (hiPSC) technology has enabled the generation of human-specific brain cell types in vitro. Here, we provide an overview of the three-dimensional (3D) hiPSC-derived neural organoid platforms used to model cortical structures and to study cortical ALS-associated phenotypes. We review which pathological hallmarks have been recapitulated in these organoids and discuss disease phenotypes reported to date. Further, we comprehensively cover different neural organoid models and experimental strategies, including patient-derived hiPSC models and exogenous pathology induction, while addressing current technical challenges. Together, these advances position neural organoids as an emerging tool to study cell-type-specific and circuit-level mechanisms related to cortical changes in ALS.\n\nID: 42375068\nTitle: Distal Motor Latency in Amyotrophic Lateral Sclerosis: A Robust and Reliable Prognostic Marker.\nAbstract: An electrophysiological test is routinely done to confirm Amyotrophic Lateral Sclerosis (ALS) and rule out differentials. Distal Motor Latency (DML) is a simple electrophysiological measure that is always done in a primary setting. It can be used as an excellent prognostic marker for ALS so that we can know ALS better and formulate precise management plans. This longitudinal study was conducted in the Neurology Department of Bangladesh Medical University (BMU), Dhaka, Bangladesh from April 2022 to October 2023. In this study a total of 34 subjects, 17 ALS patients with normal DML and 17 ALS patients with prolonged DML, were enrolled. Severity was assessed by the ALS functional rating scale-revised (ALSFRS-R). The study's endpoints were determined as death during this 6-month follow-up or reaching an advanced stage (ALSFRS-R <20). Then, an electrophysiological test was used to measure DML in all four commonly tested nerves. ALSFRS-R was significantly reduced (p<0.025) at 6 months in ALS patients with prolonged DML than normal DML. It was found that having a higher odd (p<0.012, OR=20.718), prolonged DML had a significant impact on the outcome of ALS patients than that of normal DML. In multivariate analysis, lower ALSFRS-R at diagnosis (B= -0.124, p<0.001, HR=0.883) and prolonged DML (B=1.412, p<0.031, HR=4.104) were associated with poor outcomes. ALS patients with prolonged DML also had a poorer prognosis than patients with normal DML (log-rank test, p<0.045). In this study, patients with prolonged DML had a significant functional decline, rapid disease progression and poor prognosis than patients with normal DML. So, prolonged DML can be used as a robust prognostic marker for patients with ALS.\n\nID: 42374626\nTitle: Microbiome and metabolites impact enteric and central nervous systems in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) has been linked to gastrointestinal symptoms and alterations in the gut microbiota. The enteric nervous system (ENS) coordinates intestinal function and sits at the host-microbe interface. The mechanisms by which luminal changes relay to the central nervous system (CNS), where motor neurons reside, have yet to be completely defined. In this narrative review, we first present evidence from ALS patient cohorts and preclinical models alongside mechanistic studies of infection, dysbiosis, and related neurodegenerative diseases to discuss how the microbiota and its metabolites may affect the ENS and CNS in ALS. Next, we propose a plausible mechanism of ALS pathogenesis through the gut-microbiome-brain axis. We further offer a summary of clinical trials that have studied the impacts of the microbiota on human ALS. Finally, we discuss future directions for studies of microbiota-ENS-CNS interactions in ALS. Better understanding of the dynamic interactions among the microbiota, microbial metabolites, neuroactive metabolites, and inflammation through the ENS/CNS in ALS will provide innovative insights into ALS prevention and treatment.\n\nID: 42363684\nTitle: FMRP-Mediated Proteasome Regulation: A Novel Mechanism in ALS Pathology.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a rare and fatal neurodegenerative disease characterized by the hallmark cytoplasmic accumulation and aggregation of TAR DNA binding protein 43 (TDP-43), which impairs proteasome activity through its interaction with Tankyrase (TNKS). Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43. Our results demonstrate that depletion of FMRP causes nuclear translocation of TDP-43, reducing cytoplasmic TNKS/TDP-43 co-localization, thereby releasing TNKS in the cytoplasm. Free TNKS gets associated with proteasome inhibitor of 31 kDa (PI31), reversing PI31-mediated inhibition of proteasome assembly, trafficking, and activity. Thus, FMRP regulates proteasome activity by modulating the subcellular distribution of TDP-43. Interestingly, FMRP expression is elevated in specific brain regions and spinal cords of TDP-43A315T transgenic ALS mice that helps more TDP-43 to stay in cytoplasm to sequester more TNKS with it, resulting in proteasome dysfunction in ALS disease system. We have demonstrated for the first time that FMRP can act as a disease modifier for ALS. ALS patients with high FMRP expression in the brain and spinal cord may exhibit more severe protein aggregation due to proteasome dysfunction.\n\nID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.\n\nID: 42353250\nTitle: Microglial Dysfunction Induced by C9ORF72 Dipeptide Repeat Proteins: Biomarker and Therapeutic Perspectives.\nAbstract: The GGGGCC hexanucleotide repeat expansion (HRE) in C9ORF72 was recognized as the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown. Together, these findings provided important insights into disease mechanisms and potential avenues for improved clinical management.\n\nID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype × treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\n\nID: 42352358\nTitle: Extracellular Pgk1 or Its Derived Short Peptide Interacted with Membrane-Associated Enolase 2 Receptor: A Potential Therapy for ALS Motor Neuron Degeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) remains an intractable motor neuron (MN) disease with a growing patient population and few effective treatments. Here, we review how extracellular phosphoglycerate kinase 1 (ePgk1) improves neurite outgrowth of MNs (NOMN) and axonal growth, both in vitro and in vivo. Our group first elucidated a novel non-canonical function of ePgk1 as a cross-tissue mediator between nerve and muscle tissues. We then discovered that neural membranous Enolase 2 (Eno2) serves as a receptor of ligand ePgk1 and that ePgk1-Eno2 interaction suppresses the Rac1-GTP/p-Pak1-T423/p-P38-T180/pMK2-T334/p-Limk1-S323 axis, reducing p-Cofilin and promoting NOMN and axonal growth, finally suggesting that the 419th aspartic acid residue of Eno2 mediates this interaction. In a crucial preclinical step, we truncated two short 16-amino-acid derivatives from Pgk1, FD-1/-2, each mediating neuroprotection comparable to that of full-length 417-amino-acid Pgk1 in ALS animal models, in terms of improvements of innervated neuromuscular junction, MN cell bodies, motor performance, and endpoint prolongation. In this context, we also discuss the opposite function driven by Eno1-plasminogen interaction and by Eno2-ePgk1 interaction; the latter results in unfavorable for tumorigenesis. Unlike intracellular Pgk1 roles, ePgk1 is an extracellular factor with anti-angiogenic properties, further positioning ePgk1 and its FD-1/-2 as promising protein/peptide drugs for ALS treatment.\n\nID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved α-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.\n\nID: 42349418\nTitle: The ALS- and FTD-associated proteins annexin A11 and CHMP2B act sequentially in plasma membrane repair.\nAbstract: Maintenance of plasma membrane integrity is essential for compartmentalization of the cytosol and for cellular viability. Upon membrane damage, several factors including endosomal sorting complex required for transport-III (ESCRT-III) proteins, annexins, stress granules, lipids, and membrane fusion proteins are mobilized to orchestrate membrane repair. However, whether these factors operate independently or act together is unclear. Here, using human cell lines, we expose temporal differences and interdependencies in the recruitment of ESCRT-III and annexin proteins to sites of plasma membrane damage. We show that annexin proteins are recruited immediately and form a plug at the damage site, restricting membrane permeability. We find that ESCRT-III assembles later and acts to release plug-containing damaged membranes from the cell. Further, frontotemporal dementia (FTD)- and amyotrophic lateral sclerosis (ALS)-associated mutations in the ESCRT-III protein, CHMP2B, and the annexin protein, ANXA11, compromise plasma membrane repair, suggesting that defects in this process may contribute to these pathologies. These data present an integrated \"sealing and healing\" model of membrane repair.\n\nID: 42343520\nTitle: [Effect of electroacupuncture at \"Zusanli\" (ST36) on TREM2-mediated microglial activation in amyotrophic lateral sclerosis mice].\nAbstract: To observe the effect of electroacupuncture (EA) at \"Zusanli\" (ST36) on amyotrophic lateral sclerosis (ALS) in mouse models based on myeloid cell trigger receptor 2 (TREM2)-mediated microglial activation. Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1β, γ interferon (IFN-γ), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1β, IFN-γ, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1β and IFN-γ decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1β,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05). Electroacupuncture at \"Zusanli\" (ST36) exhibits a certain improvements in motor function of SOD1-G93A transgenic mice. The underlying mechanism may be related to attenuating neuroinflammation via the modulation of microglial activation mediated by TREM2. 目的：基于髓样细胞触发受体2（TREM2）介导的小胶质细胞活化观察电针“足三里”对肌萎缩侧索硬化症模型小鼠神经炎症的影响。 方法：将36只SPF级雄性人突变型超氧化物歧化酶1（SOD1-G93A）转基因小鼠随机分为模型组、电针组、药物组，每组12只；选取12只同窝野生小鼠作为对照组。电针组于“足三里”进行电针干预，采用断续波，频率15 Hz，每次10 min，隔日1次，每周3次，共4周；药物组予利鲁唑溶液（8 mg/kg）灌胃，每日1次，共4周。干预结束后，应用转棒测试与钢丝悬挂测试评估各组小鼠行为学，HE染色和尼氏染色观察各组小鼠脊髓前角运动神经元形态，免疫荧光法检测各组小鼠脊髓前角TREM2荧光强度，Western blot法检测各组小鼠脊髓组织白细胞介素（IL）-1β、γ干扰素（IFN-γ）、IL-4、IL-10蛋白表达，流式细胞术检测各组小鼠脊髓组织单细胞悬液CD86+和CD206+细胞比例。 结果：与对照组比较，模型组小鼠脊髓前角运动神经元排列紊乱，出现核固缩、胞体皱缩等现象；转棒测试潜伏期和钢丝悬挂测试掉落时间缩短，脊髓前角TREM2荧光强度升高，脊髓组织IL-1β、IFN-γ、IL-4、IL-10蛋白表达升高，脊髓组织单细胞悬液CD86+、CD206+细胞比例升高（P<0.01）。与模型组比较，电针组和药物组小鼠脊髓前角运动神经元排列较规整，核固缩及尼氏小体溶解丢失现象改善，神经元结构完整性提高；转棒测试潜伏期和钢丝悬挂测试掉落时间延长，脊髓前角TREM2荧光强度降低，脊髓组织IL-1β、IFN-γ蛋白表达降低，IL-4、IL-10蛋白表达升高，脊髓组织CD86+细胞比例降低，CD206+细胞比例升高（P<0.01，P<0.05）。与药物组比较，电针组脊髓组织IL-1β蛋白表达升高，IL-4、IL-10蛋白表达降低，CD206+细胞比例降低（P<0.05）。 结论：电针“足三里”对SOD1-G93A转基因小鼠运动功能具有一定的改善作用，其作用机制可能为调控TREM2介导的小胶质细胞活化，进而改善神经炎症。.\n\nID: 42341118\nTitle: Isoform-specific steric zippers drive aberrant assembly and mislocalization of shortened TDP-43.\nAbstract: Prion-like domain (PrLD)-mediated aggregation and concomitant dysfunction of the essential RNA-binding protein transactive response (TAR) DNA-binding protein of 43 kilodaltons (TDP-43) is a common feature of multiple debilitating neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). However, shortened TDP-43 (sTDP-43) splice isoforms where the PrLD is largely replaced by an 18-residue carboxyl-terminal tail also contribute to ALS pathophysiology and are enriched in motor neurons. Curiously, despite lacking most of the PrLD, sTDP-43 exhibits pronounced insolubility in cells and tissue of patients with ALS. Here, we establish that the short, isoform-specific carboxyl-terminal tail of sTDP-43 confers high aggregation propensity, which is encoded by two clusters of steric zippers, and can be mitigated by short RNA chaperones. Disrupting these zippers enhances sTDP-43 solubility at the pure protein level and in neurons. Notably, these steric zippers, rather than a predicted nuclear export signal in the carboxyl-terminal tail, drive cytoplasmic mislocalization and aggregation of sTDP-43 in neurons. Thus, we define the sequence-encoded determinants of aberrant sTDP-43 assembly and provide mechanistic insights into sTDP-43 disease pathology.\n\nID: 42337904\nTitle: Are patient-derived models of amyotrophic lateral sclerosis a game changer for novel drug discovery?\nAbstract: ALS drug discovery has long depended on model systems that incompletely capture human disease heterogeneity, aging, and TDP-43 proteinopathy. Patient-derived platforms have therefore emerged as increasingly important human-relevant complements to animal and molecular models. This Critical Perspective examines when patient-derived ALS models genuinely change therapeutic decision-making rather than merely add mechanistic insight. The authors then propose a heuristic framework based on disease-relevant phenotype recapitulation, capture of patient-to-patient heterogeneity, and generation of findings that influence therapeutic prioritization or clinical translation. Furthermore, the authors evaluate iPSC-derived motor neurons, directly reprogrammed neurons, glial co-cultures, organoids, neural networks, and organ-chip systems against these conditions, while also addressing aging fidelity, reproducibility, upper motor neuron modeling, and regulatory implementation. Patient-derived models are not yet standalone decision-grade tools for ALS drug development. Their present value lies in functioning as a human-biology filter for target discovery, reverse translation, biomarker development, and patient stratification when used within rigorous, standardized, and clinically linked workflows. The strongest current evidence supports proof-of-principle rather than generalized predictive validity.\n\nID: 42371122\nTitle: Quantification of amyotrophic lateral sclerosis (ALS) disease accumulation with T1-weighted high-resolution magnetic resonance imaging: validation in an independent cohort.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a progressive neuromuscular disease with multifaceted phenotypic presentation thus obstructing objective disease staging. The D50 disease progression model is a framework to comprehensively dissect biomarker-signals towards their relevance regarding disease accumulation/phase (rD50), or disease aggressiveness (D50). Based on previous findings using 1.5-Tesla Magnetic-Resonance-Imaging (MRI), this study hypothesized that high-resolution MRI markers of Grey-Matter (GM) structural integrity would enable quantification of disease accumulation, independent of aggressiveness. A separate cohort of 75 patients with ALS and 73 Healthy Controls (HC) underwent T1-weighted 3-Tesla MRI. Voxel-Based-Morphometry measured GM and White-Matter (WM) density and Surface-Based-Morphometry assessed Cortical Thickness (CT). Non-parametric Threshold-Free-Cluster-Enhancement with 5000 permutations was applied for inter-group and regression contrasts, whilst correcting for possibly interfering co-variates and applying Family-Wise-Error-adjustment. Compared with HC, the ALS cohort showed widespread decreases of CT and GM/WM density (p < 0.001). These case-control effects were driven by patients scanned during rD50-defined disease Phase 2 (p < 0.001). Within the ALS-cohort, direct Phase 2 versus Phase 1 contrasts revealed spatially-distributed decreases, reflecting higher disease accumulation (p < 0.05). These were independent of disease aggressiveness (and onset-region), as corrected for in the models. Accordingly, all contrasts assessing aggressiveness did not yield significant results. These semi-automated analyses of T1-weighted-images captured disease accumulation related GM structural integrity-loss in this cohort scanned with 3-Tesla MRI, independent of the underlying disease aggressiveness. This principle was validated across different scanners and field strengths, supporting its application for objective and non-invasive staging of patients with ALS, whereby true longitudinal studies are necessary.\n\nID: 42365390\nTitle: Lysophagy protects against ANXA11 amyloid fibril toxicity and propagation in FTLD.\nAbstract: Accumulation of Annexin A11 (ANXA11) aggregates is a distinct pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS.\n\nID: 42364760\nTitle: The impedance mismatch theory: A non-equilibrium thermodynamic framework for a shared energetic stress pathway in neurodegeneration.\nAbstract: Current neurobiological models of Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's Disease (HD) utilize multi-omic interactome analyses to map cascades of proteinopathy. While essential, these approaches often overlook the macroscopic thermodynamic limits of the neural substrate as an information processing system. We propose the Impedance Mismatch Theory, a theoretical biophysical model and quantitative framework for the thermodynamic limits of neural computation, positing that these distinct pathologies converge as a shared energetic stress pathway. We introduce the Neurophysiological Load Index (NLI)-a dimensionless parameter quantifying the mismatch between electrical computational drive, topological network impedance, and the local structural and microvascular dissipation capacity. Drawing on the Pennes Bioheat Transfer Equation and insights from multiplex network theory, we hypothesize that pathology initiates as localized thermal runaway, where resistive metabolic heat exceeds convective blood perfusion and thermal conduction, inducing acute decompensation. We outline cross-translational disease-network mechanisms, address the inverse cancer comorbidity paradox via speculative bioelectric attractor states, and propose falsifiable predictions involving high-resolution in vivo proton magnetic resonance spectroscopy thermometry (1H-MRS-t) and phosphorus-31 magnetic resonance spectroscopy (31P-MRS).\n\nID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.\n\nID: 42373582\nTitle: Unravelling the Significance of Cystatin C and Bunina Bodies in Amyotrophic Lateral Sclerosis Pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a fatal neurodegenerative disease primarily affecting motor neurons. Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential. A deeper understanding of cystatin C biology, its relationship with TDP43 pathology and improved ALS models will be essential for determining whether targeting cystatin C could provide a viable avenue for future ALS therapies.\n\nID: 42360563\nTitle: Characterization of sensory nerve conduction abnormalities at the time of ALS diagnosis.\nAbstract: Although sensory nerve abnormalities have been reported in amyotrophic lateral sclerosis (ALS), their distribution at diagnosis, relative to motor involvement and clinical onset phenotype remains incompletely characterized. We aimed to systematically compare sensory and motor nerve conduction abnormalities at ALS diagnosis and determine whether sensory involvement follows an onset-dependent pattern similar to motor dysfunction. In this prospective cross-sectional study, 40 newly diagnosed ALS patients enrolled in the Iran University ALS Registry (March 2022-March 2023) underwent standardized motor and sensory nerve conduction studies (NCS). For between-group comparisons, a matched ALS subgroup was compared with matched healthy controls, while the expanded ALS cohort was used for subgroup and correlation analyses. SNAP amplitudes of the median, ulnar, and sural nerves were reduced by 45%, 34%, and 43%, respectively, compared with healthy controls, with similar reductions observed across upper- and lower-limb onset phenotypes and no significant onset-dependent differences. In contrast CMAP amplitudes were markedly reduced in ALS patients, most prominently in the peroneal (79%), median (47%), tibial (42%), and ulnar (37%) nerves. Motor abnormalities were most severe in the clinically affected limb but were also detectable in asymptomatic extremities, consistent with early subclinical spread. At ALS diagnosis, sensory and motor nerve conduction abnormalities exhibited divergent spatial patterns, with asymmetric, onset-related motor involvement and relatively uniform sensory axonal dysfunction. These findings support the presence of measurable sensory nerve conduction abnormalities in a subset of ALS patients, while highlighting the need for cautious interpretation of sensory NCS changes in ALS.\n\nID: 42297981\nTitle: Plasma proteomic signatures of cellular aging predict human disease.\nAbstract: Aging is asynchronous across cells and organs. Here we tested whether plasma proteomics can be used to analyze cell type-specific aging. From analyses of over 7,000 plasma proteins measured in 60,542 individuals, we developed machine learning models to estimate the biological age of over 40 cell types spanning neuronal, immune, glial, endocrine, epithelial and musculoskeletal origins. We observed that 20-25% of individuals exhibited accelerated aging in a single cell type and 1-3% in 10 or more cell types. Cellular aging signatures were associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Individuals with the APOE4 genotype showed older astrocytes but younger macrophages compared to APOE3 carriers, whereas the APOE2 genotype had inverse associations. Moreover, extreme astrocyte aging tripled the risk of incident Alzheimer's Disease in individuals with two APOE4 alleles, while youthful astrocytes reduced risk. Individuals with extremely aged compared to youthful skeletal myocytes exhibited a 12.7-fold higher risk of developing amyotrophic lateral sclerosis. In individuals who smoked, extreme respiratory epithelial cell aging was associated with a 58% higher lung cancer risk compared to smoking alone. Specific cellular vulnerabilities and cumulative cellular aging burden influenced survival, with youthful immune and neuronal cell types conferring protective effects. Finally, we developed a polycellular aging risk score that stratified mortality risk across cohorts and proteomics platforms. These findings establish a framework for quantifying human physiology at cellular resolution, revealing heterogeneous aging trajectories and their impact on disease susceptibility and resilience.\n\nID: 42222887\nTitle: Multimodal analysis of cell-free DNA identifies epigenetic biomarkers for amyotrophic lateral sclerosis diagnosis and progression.\nAbstract: The role of the epigenome in age-related neurodegenerative disorders remains understudied. Here, we analyzed circulating cell-free DNA (cfDNA) from blood to detect methylation changes as a liquid biopsy for Amyotrophic Lateral Sclerosis (ALS). Our study included 20 patients with sporadic ALS, 10 patients with C9orf72-associated ALS, 10 asymptomatic carriers of the C9orf72 repeat expansion mutation, and 21 nondisease control individuals. Following targeted enzymatic methyl-sequencing (EM-seq) of approximately 4 million CpG sites, we detected numerous differentially methylated genes, including several implicated in ALS disease risk and pathogenesis. By integrating multiple epigenetic features, we delineated a distinct epigenetic signature, which achieved an average area under the curve (AUC) of 0.91 ± 0.10 upon receiver operator characteristic (ROC) analysis, which enabled detection of approximately 70% of patients with ALS with close to 100% specificity. Furthermore, we also identified a set of genes whose methylation status significantly correlated with clinical disease progression and cerebrospinal fluid (CSF) neurofilament levels. Our results reveal the potential of cfDNA-based biomarkers to accurately diagnose ALS and potentially predict disease progression.\n\nID: 42207242\nTitle: Anchoring ALS Prognosis: Neurofilament Light Chain Outperforms Inflammatory, Metabolic, and CNS Barrier Biomarkers in the METABALS Cohort.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rapidly progressive and fatal neurodegenerative disorder with marked biological heterogeneity. Despite extensive research, reliable prognostic biomarkers remain limited, with neurofilament light chain (NfL) being the only marker increasingly implemented in clinical practice. The objective of this study is to assess and compare the prognostic value of NfL, circulating markers of central nervous system (CNS) barrier dysfunction, inflammatory mediators, kynurenine pathway metabolites, and global metabolomic profiles in patients with ALS. Seventy-two patients with ALS from the prospective multicenter METABALS cohort were included. Serum, cerebrospinal fluid (CSF), and urine samples were collected at diagnosis. NfL concentrations, markers of blood-brain and blood-spinal cord barrier permeability (albumin quotient, S100B, neuron-specific enolase [NSE]), 48 inflammatory mediators, kynurenine pathway metabolites, and untargeted metabolomic profiles were measured. Associations with clinical features, disease progression, and survival were investigated using univariate analyses and multivariate models. Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival. Higher serum NfL concentrations at diagnosis predicted shorter survival (ROC AUC = 0.86). In all multivariate and multi-block models, serum NfL was the only biomarker independently associated with survival. Markers of CNS barrier integrity, inflammatory mediators, and metabolomic signatures showed limited prognostic value but provided insights into metabolic remodeling and barrier dysfunction. In this integrated multi-omics study, serum NfL clearly outperformed inflammatory, metabolic, and CNS barrier markers as a prognostic biomarker in ALS, supporting its central role in clinical stratification while complementary biological markers highlighted several relevant pathophysiological mechanisms.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

Here, we review how extracellular phosphoglycerate kinase 1 (ePgk1) improves neurite outgrowth of MNs (NOMN) and axonal growth, both in vitro and in vivo. Our group first elucidated a novel non-canonical function of ePgk1 as a cross-tissue mediator between nerve and muscle tissues. We then discovered that neural membranous Enolase 2 (Eno2) serves as a receptor of ligand ePgk1 and that ePgk1-Eno2 interaction suppresses the Rac1-GTP/p-Pak1-T423/p-P38-T180/pMK2-T334/p-Limk1-S323 axis, reducing p-Cofilin and promoting NOMN and axonal growth, finally suggesting that the 419th aspartic acid residue of Eno2 mediates this interaction. In a crucial preclinical step, we truncated two short 16-amino-acid derivatives from Pgk1, FD-1/-2, each mediating neuroprotection comparable to that of full-length 417-amino-acid Pgk1 in ALS animal models, in terms of improvements of innervated neuromuscular junction, MN cell bodies, motor performance, and endpoint prolongation. In this context, we also discuss the opposite function driven by Eno1-plasminogen interaction and by Eno2-ePgk1 interaction; the latter results in unfavorable for tumorigenesis. Unlike intracellular Pgk1 roles, ePgk1 is an extracellular factor with anti-angiogenic properties, further positioning ePgk1 and its FD-1/-2 as promising protein/peptide drugs for ALS treatment.\n  --- END ACTUAL ABSTRACT FOR 42352358 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"the success rate of developing drugs for neurological disorders is significantly low.\" (Source: 42432671)\n- \"the blood-brain barrier (BBB) emerges as one of the key challenges in the development and application of drugs against neurological disorders.\" (Source: 42432671)\n- \"Elevated mitochondrial R-loop signal was also detected in a pilot cohort of sporadic ALS samples carrying rs2293925 and in neural stem cells derived from C9orf72-positive ALS patients.\" (Source: 42419740)\n- \"The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease.\" (Source: 42411482)\n- \"The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders.\" (Source: 42407013)\n- \"Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis.\" (Source: 42397462)\n- \"The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.\" (Source: 42384233)\n- \"The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS.\" (Source: 42383305)\n- \"Simulated disease trajectories of MUNE values derived from CMAP scans in muscles affected by ALS indicated that MUNE may reach 50% of its maximum in approximately 60% of the time compared to functional impairment.\" (Source: 42434198)\n- \"These findings suggest that neck EMG signals can reliably predict intended head movements in ALS, even in the presence of weak and often confounding muscle activity.\" (Source: 42430317)\n- \"Younger ALS caregivers appear to have distinct experiences and needs, yet age- or life-stage variations and processes of caregiving are seldom considered in studies of ALS family caregiver experience.\" (Source: 42436431)\n- \"Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43.\" (Source: 42363684)\n- \"DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response.\" (Source: 42362484)\n- \"Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms.\" (Source: 42353250)\n- \"Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.\" (Source: 42353064)\n- \"A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved α-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function.\" (Source: 42350385)\n- \"These semi-automated analyses of T1-weighted-images captured disease accumulation related GM structural integrity-loss in this cohort scanned with 3-Tesla MRI, independent of the underlying disease aggressiveness.\" (Source: 42371122)\n- \"We propose the Impedance Mismatch Theory, a theoretical biophysical model and quantitative framework for the thermodynamic limits of neural computation, positing that these distinct pathologies converge as a shared energetic stress pathway.\" (Source: 42364760)\n- \"Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS.\" (Source: 42351313)\n- \"Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis.\" (Source: 42373582)\n\n\nINSTRUCTION: Study the actual abstracts provided.

(ALS) is a rapidly progressive and fatal neurodegenerative disorder with marked biological heterogeneity. Despite extensive research, reliable prognostic biomarkers remain limited, with neurofilament light chain (NfL) being the only marker increasingly implemented in clinical practice. The objective of this study is to assess and compare the prognostic value of NfL, circulating markers of central nervous system (CNS) barrier dysfunction, inflammatory mediators, kynurenine pathway metabolites, and global metabolomic profiles in patients with ALS. Seventy-two patients with ALS from the prospective multicenter METABALS cohort were included. Serum, cerebrospinal fluid (CSF), and urine samples were collected at diagnosis. NfL concentrations, markers of blood-brain and blood-spinal cord barrier permeability (albumin quotient, S100B, neuron-specific enolase [NSE]), 48 inflammatory mediators, kynurenine pathway metabolites, and untargeted metabolomic profiles were measured. Associations with clinical features, disease progression, and survival were investigated using univariate analyses and multivariate models. Serum and CSF NfL concentrations were strongly associated with ALS Functional Rating Scale-Revised scores, respiratory function, diagnostic delay, and survival. Higher serum NfL concentrations at diagnosis predicted shorter survival (ROC AUC = 0.86). In all multivariate and multi-block models, serum NfL was the only biomarker independently associated with survival. Markers of CNS barrier integrity, inflammatory mediators, and metabolomic signatures showed limited prognostic value but provided insights into metabolic remodeling and barrier dysfunction. In this integrated multi-omics study, serum NfL clearly outperformed inflammatory, metabolic, and CNS barrier markers as a prognostic biomarker in ALS, supporting its central role in clinical stratification while complementary biological markers highlighted several relevant pathophysiological mechanisms.","42222887":"ID: 42222887\nTitle: Multimodal analysis of cell-free DNA identifies epigenetic biomarkers for amyotrophic lateral sclerosis diagnosis and progression.\nAbstract: The role of the epigenome in age-related neurodegenerative disorders remains understudied. Here, we analyzed circulating cell-free DNA (cfDNA) from blood to detect methylation changes as a liquid biopsy for Amyotrophic Lateral Sclerosis (ALS). Our study included 20 patients with sporadic ALS, 10 patients with C9orf72-associated ALS, 10 asymptomatic carriers of the C9orf72 repeat expansion mutation, and 21 nondisease control individuals. Following targeted enzymatic methyl-sequencing (EM-seq) of approximately 4 million CpG sites, we detected numerous differentially methylated genes, including several implicated in ALS disease risk and pathogenesis. By integrating multiple epigenetic features, we delineated a distinct epigenetic signature, which achieved an average area under the curve (AUC) of 0.91 ± 0.10 upon receiver operator characteristic (ROC) analysis, which enabled detection of approximately 70% of patients with ALS with close to 100% specificity. Furthermore, we also identified a set of genes whose methylation status significantly correlated with clinical disease progression and cerebrospinal fluid (CSF) neurofilament levels. Our results reveal the potential of cfDNA-based biomarkers to accurately diagnose ALS and potentially predict disease progression.","42297981":"ID: 42297981\nTitle: Plasma proteomic signatures of cellular aging predict human disease.\nAbstract: Aging is asynchronous across cells and organs. Here we tested whether plasma proteomics can be used to analyze cell type-specific aging. From analyses of over 7,000 plasma proteins measured in 60,542 individuals, we developed machine learning models to estimate the biological age of over 40 cell types spanning neuronal, immune, glial, endocrine, epithelial and musculoskeletal origins. We observed that 20-25% of individuals exhibited accelerated aging in a single cell type and 1-3% in 10 or more cell types. Cellular aging signatures were associated with disease status and predicted incident disease and mortality over 15 years of follow-up. Individuals with the APOE4 genotype showed older astrocytes but younger macrophages compared to APOE3 carriers, whereas the APOE2 genotype had inverse associations. Moreover, extreme astrocyte aging tripled the risk of incident Alzheimer's Disease in individuals with two APOE4 alleles, while youthful astrocytes reduced risk. Individuals with extremely aged compared to youthful skeletal myocytes exhibited a 12.7-fold higher risk of developing amyotrophic lateral sclerosis. In individuals who smoked, extreme respiratory epithelial cell aging was associated with a 58% higher lung cancer risk compared to smoking alone. Specific cellular vulnerabilities and cumulative cellular aging burden influenced survival, with youthful immune and neuronal cell types conferring protective effects. Finally, we developed a polycellular aging risk score that stratified mortality risk across cohorts and proteomics platforms. These findings establish a framework for quantifying human physiology at cellular resolution, revealing heterogeneous aging trajectories and their impact on disease susceptibility and resilience.","42337904":"ID: 42337904\nTitle: Are patient-derived models of amyotrophic lateral sclerosis a game changer for novel drug discovery?\nAbstract: ALS drug discovery has long depended on model systems that incompletely capture human disease heterogeneity, aging, and TDP-43 proteinopathy. Patient-derived platforms have therefore emerged as increasingly important human-relevant complements to animal and molecular models. This Critical Perspective examines when patient-derived ALS models genuinely change therapeutic decision-making rather than merely add mechanistic insight. The authors then propose a heuristic framework based on disease-relevant phenotype recapitulation, capture of patient-to-patient heterogeneity, and generation of findings that influence therapeutic prioritization or clinical translation. Furthermore, the authors evaluate iPSC-derived motor neurons, directly reprogrammed neurons, glial co-cultures, organoids, neural networks, and organ-chip systems against these conditions, while also addressing aging fidelity, reproducibility, upper motor neuron modeling, and regulatory implementation. Patient-derived models are not yet standalone decision-grade tools for ALS drug development. Their present value lies in functioning as a human-biology filter for target discovery, reverse translation, biomarker development, and patient stratification when used within rigorous, standardized, and clinically linked workflows. The strongest current evidence supports proof-of-principle rather than generalized predictive validity.","42341118":"ID: 42341118\nTitle: Isoform-specific steric zippers drive aberrant assembly and mislocalization of shortened TDP-43.\nAbstract: Prion-like domain (PrLD)-mediated aggregation and concomitant dysfunction of the essential RNA-binding protein transactive response (TAR) DNA-binding protein of 43 kilodaltons (TDP-43) is a common feature of multiple debilitating neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). However, shortened TDP-43 (sTDP-43) splice isoforms where the PrLD is largely replaced by an 18-residue carboxyl-terminal tail also contribute to ALS pathophysiology and are enriched in motor neurons. Curiously, despite lacking most of the PrLD, sTDP-43 exhibits pronounced insolubility in cells and tissue of patients with ALS. Here, we establish that the short, isoform-specific carboxyl-terminal tail of sTDP-43 confers high aggregation propensity, which is encoded by two clusters of steric zippers, and can be mitigated by short RNA chaperones. Disrupting these zippers enhances sTDP-43 solubility at the pure protein level and in neurons. Notably, these steric zippers, rather than a predicted nuclear export signal in the carboxyl-terminal tail, drive cytoplasmic mislocalization and aggregation of sTDP-43 in neurons. Thus, we define the sequence-encoded determinants of aberrant sTDP-43 assembly and provide mechanistic insights into sTDP-43 disease pathology.","42343520":"ID: 42343520\nTitle: [Effect of electroacupuncture at \"Zusanli\" (ST36) on TREM2-mediated microglial activation in amyotrophic lateral sclerosis mice].\nAbstract: To observe the effect of electroacupuncture (EA) at \"Zusanli\" (ST36) on amyotrophic lateral sclerosis (ALS) in mouse models based on myeloid cell trigger receptor 2 (TREM2)-mediated microglial activation. Thirty-six SPF-grade male human mutant superoxide dismutase 1 (SOD1-G93A) transgenic mice were divided into a model group, an EA group, and a drug group, 12 mice in each group. Besides, 12 wide-type littermates were collected as a control group. In the EA group, EA was performed at the \"Zusanli\" (ST36), with an intermittent wave, at the frequency of 15 Hz, and for 10 min each intervention; once every other day, 3 interventions a week and for 4 continuous weeks. In the drug group, the intragastric administration of riluzole solution was given at 8 mg/kg, once daily, for 4 continuous weeks. After intervention completion, behavioral assessment of mice was conducted using rotarod test and wire hang test. With HE and Nissl staining adopted, morphology of motor neurons in the anterior horn of the spinal cord was observed. Immunofluorescence was used to detect the fluorescence intensity of TREM2 in the anterior horn of spinal cord. Western blot analysis was performed to measure the protein expression of interleukin (IL)-1β, γ interferon (IFN-γ), IL-4 and IL-10 in spinal cord tissue. Flow cytometry was used to analyze the proportion of CD86+ and CD206+ in spinal cord monocyte suspension. Compared with the control group, in the model group, motor neurons in the anterior horn of the spinal cord exhibited disordered arrangement; accompanied by nuclear pyknosis and cytoplasmic shrinkage; the latency to fall in the rotarod test and the cut-off time in the wire hang test were shortened, fluorescence intensity of TREM2 in the spinal anterior horn, the protein expression of IL-1β, IFN-γ, IL-4, and IL-10, and the proportion of CD86+ and CD206+ in spinal cord tissue increased(P<0.01). When compared with the model group, in the EA and drug groups, motor neurons in the anterior horn of the spinal cord were arranged regularly; nuclear pyknosis and chromatolysis were attenuated, and the structural integrity of neurons was improved; the latency to fall and the the cut-off time were prolonged, fluorescence intensity of TREM2 in the spinal anterior horn was reduced, the protein expression of IL-1β and IFN-γ decreased, and that of IL-4, and IL-10 increased in the spinal cord tissue; the proportion of CD86+ in spinal cord tissue was reduced and that of CD206+ elevated(P<0.01, P<0.05). Compared with the drug group, the EA group showed the increase of protein expression of IL-1β,and the decrease of IL-4, IL-10 in the spinal cord tissue and the proportion of CD206+ (P<0.05). Electroacupuncture at \"Zusanli\" (ST36) exhibits a certain improvements in motor function of SOD1-G93A transgenic mice. The underlying mechanism may be related to attenuating neuroinflammation via the modulation of microglial activation mediated by TREM2. 目的：基于髓样细胞触发受体2（TREM2）介导的小胶质细胞活化观察电针“足三里”对肌萎缩侧索硬化症模型小鼠神经炎症的影响。 方法：将36只SPF级雄性人突变型超氧化物歧化酶1（SOD1-G93A）转基因小鼠随机分为模型组、电针组、药物组，每组12只；选取12只同窝野生小鼠作为对照组。电针组于“足三里”进行电针干预，采用断续波，频率15 Hz，每次10 min，隔日1次，每周3次，共4周；药物组予利鲁唑溶液（8 mg/kg）灌胃，每日1次，共4周。干预结束后，应用转棒测试与钢丝悬挂测试评估各组小鼠行为学，HE染色和尼氏染色观察各组小鼠脊髓前角运动神经元形态，免疫荧光法检测各组小鼠脊髓前角TREM2荧光强度，Western blot法检测各组小鼠脊髓组织白细胞介素（IL）-1β、γ干扰素（IFN-γ）、IL-4、IL-10蛋白表达，流式细胞术检测各组小鼠脊髓组织单细胞悬液CD86+和CD206+细胞比例。 结果：与对照组比较，模型组小鼠脊髓前角运动神经元排列紊乱，出现核固缩、胞体皱缩等现象；转棒测试潜伏期和钢丝悬挂测试掉落时间缩短，脊髓前角TREM2荧光强度升高，脊髓组织IL-1β、IFN-γ、IL-4、IL-10蛋白表达升高，脊髓组织单细胞悬液CD86+、CD206+细胞比例升高（P<0.01）。与模型组比较，电针组和药物组小鼠脊髓前角运动神经元排列较规整，核固缩及尼氏小体溶解丢失现象改善，神经元结构完整性提高；转棒测试潜伏期和钢丝悬挂测试掉落时间延长，脊髓前角TREM2荧光强度降低，脊髓组织IL-1β、IFN-γ蛋白表达降低，IL-4、IL-10蛋白表达升高，脊髓组织CD86+细胞比例降低，CD206+细胞比例升高（P<0.01，P<0.05）。与药物组比较，电针组脊髓组织IL-1β蛋白表达升高，IL-4、IL-10蛋白表达降低，CD206+细胞比例降低（P<0.05）。 结论：电针“足三里”对SOD1-G93A转基因小鼠运动功能具有一定的改善作用，其作用机制可能为调控TREM2介导的小胶质细胞活化，进而改善神经炎症。.","42349418":"ID: 42349418\nTitle: The ALS- and FTD-associated proteins annexin A11 and CHMP2B act sequentially in plasma membrane repair.\nAbstract: Maintenance of plasma membrane integrity is essential for compartmentalization of the cytosol and for cellular viability. Upon membrane damage, several factors including endosomal sorting complex required for transport-III (ESCRT-III) proteins, annexins, stress granules, lipids, and membrane fusion proteins are mobilized to orchestrate membrane repair. However, whether these factors operate independently or act together is unclear. Here, using human cell lines, we expose temporal differences and interdependencies in the recruitment of ESCRT-III and annexin proteins to sites of plasma membrane damage. We show that annexin proteins are recruited immediately and form a plug at the damage site, restricting membrane permeability. We find that ESCRT-III assembles later and acts to release plug-containing damaged membranes from the cell. Further, frontotemporal dementia (FTD)- and amyotrophic lateral sclerosis (ALS)-associated mutations in the ESCRT-III protein, CHMP2B, and the annexin protein, ANXA11, compromise plasma membrane repair, suggesting that defects in this process may contribute to these pathologies. These data present an integrated \"sealing and healing\" model of membrane repair.","42350385":"ID: 42350385\nTitle: Intravenous administration of an engineered AAV9-gene-silencing vector suppresses human SOD1 and extends survival in an ALS mouse model.\nAbstract: Adeno-associated virus (AAV)-mediated gene silencing offers a promising strategy for achieving durable therapeutic effects with a single administration. Mutations in the human superoxide dismutase 1 (hSOD1) gene, inherited in an autosomal dominant manner, lead to motor neuron degeneration in amyotrophic lateral sclerosis (ALS)-a fatal neurodegenerative disease with no effective treatment. In this study, we employed AAV9 to deliver to the SOD1G93A ALS mouse model artificial microRNAs targeting SOD1, embedded in dual miR-33 scaffolds driven by the promoter of the human survival motor neuron 1 (hSMN1) gene. A single intravenous injection achieved widespread and sustained suppression of SOD1, preserved α-motor neurons, maintained neuromuscular junctions (NMJs), and improved muscle function. These benefits are translated into significantly improved respiratory function, motor performance, and survival. Therapeutic efficacy was observed both when the treatment was administered pre-symptomatically and during symptomatic stages. Compared with previous AAV-based interventions, the survival benefit achieved in this IV delivery approach is unprecedented, supporting its potential for clinical translation in SOD1-linked ALS and other central nervous system (CNS) diseases caused by gain-of-toxicity gene mutations.","42351313":"ID: 42351313\nTitle: A rare missense variant impacting NEK1 kinase function is associated with ALS.\nAbstract: Heterozygous truncating loss-of-function (LoF) variants in NEK1 are a known cause of amyotrophic lateral sclerosis (ALS). NEK1 encodes the pleiotropic serine/threonine kinase NIMA-related kinase 1, and prior in vitro studies have implicated kinase dysfunction as the principal pathogenic mechanism underlying NEK1-associated ALS. However, bona fide pathogenic missense variants causally linked to ALS have not previously been reported, leaving this hypothesis unconfirmed. Here, we identify a rare NEK1 missense variant, p.N598S, that co-segregates with disease in a familial ALS pedigree and is enriched in European ALS cohorts. This variant exhibits normal protein expression levels, indicating a functional rather than quantitative defect. Using isogenic human motor neurons, we directly compared the effects of p.N598S with those of the ALS-associated truncating variant p.R812* to delineate disease mechanisms. The p.N598S variant induced pathological phenotypes consistent with NEK1 haploinsufficiency, including increased susceptibility to DNA damage, increased apoptosis, ciliary dysmorphia, and nucleocytoplasmic translocation of TDP-43. Importantly, p.N598S impaired NEK1 kinase activity, and pharmacological inhibition of NEK1 recapitulated the cellular phenotypes observed in both p.N598S- and p.R812*-mutant motor neurons. Collectively, these findings provide strong genetic and functional evidence for a disease-causing role of NEK1 kinase disruption in NEK1-ALS. Our findings provide immediate diagnostic and therapeutic implications, particularly for the functional interpretation of missense variants of uncertain significance and the development of targeted treatment strategies.","42352358":"ID: 42352358\nTitle: Extracellular Pgk1 or Its Derived Short Peptide Interacted with Membrane-Associated Enolase 2 Receptor: A Potential Therapy for ALS Motor Neuron Degeneration.\nAbstract: Amyotrophic lateral sclerosis (ALS) remains an intractable motor neuron (MN) disease with a growing patient population and few effective treatments. Here, we review how extracellular phosphoglycerate kinase 1 (ePgk1) improves neurite outgrowth of MNs (NOMN) and axonal growth, both in vitro and in vivo. Our group first elucidated a novel non-canonical function of ePgk1 as a cross-tissue mediator between nerve and muscle tissues. We then discovered that neural membranous Enolase 2 (Eno2) serves as a receptor of ligand ePgk1 and that ePgk1-Eno2 interaction suppresses the Rac1-GTP/p-Pak1-T423/p-P38-T180/pMK2-T334/p-Limk1-S323 axis, reducing p-Cofilin and promoting NOMN and axonal growth, finally suggesting that the 419th aspartic acid residue of Eno2 mediates this interaction. In a crucial preclinical step, we truncated two short 16-amino-acid derivatives from Pgk1, FD-1/-2, each mediating neuroprotection comparable to that of full-length 417-amino-acid Pgk1 in ALS animal models, in terms of improvements of innervated neuromuscular junction, MN cell bodies, motor performance, and endpoint prolongation. In this context, we also discuss the opposite function driven by Eno1-plasminogen interaction and by Eno2-ePgk1 interaction; the latter results in unfavorable for tumorigenesis. Unlike intracellular Pgk1 roles, ePgk1 is an extracellular factor with anti-angiogenic properties, further positioning ePgk1 and its FD-1/-2 as promising protein/peptide drugs for ALS treatment.","42353064":"ID: 42353064\nTitle: Chronic Diazepam Reveals Excessive Homeostatic Gain in SOD1G93A Mouse Spinal Motoneurons.\nAbstract: Motoneurons are under strong pressure to maintain stable motor output throughout an individual life, through homeostatic regulation of their electrical properties. Dysregulated spinal motoneuron excitability has long been implicated in the pathogenesis of amyotrophic lateral sclerosis (ALS). Recent work in SOD1G93A mice suggests that the homeostatic response of motoneurons becomes dysregulated as cellular processes are disrupted by the disease, causing fluctuations in motoneuron electrical properties. Yet, few studies directly test whether ALS motoneurons respond differently than wild-type motoneurons to a common chronic perturbation. Here, we used in vivo electrophysiology to test whether motoneurons from pre-symptomatic SOD1G93A mice modulate excitability differently than wild-type motoneurons in response to the same homeostatic perturbation: chronic inhibition exerted by the benzodiazepine diazepam. Using linear mixed-effects statistical models, we assessed whether diazepam treatment differentially modulated passive properties, firing behavior, spike properties, and/or synaptic inputs in SOD1G93A versus wild-type motoneurons. We identified a significant genotype × treatment interaction effect selectively for properties related to passive membrane integration and spike initiation, including membrane time constant, peak input resistance, and recruitment current. In contrast, firing gain, spike waveform characteristics, and synaptic inputs were largely unaffected. These findings indicate that sustained inhibitory perturbation selectively triggered overactive intrinsic compensatory mechanisms in SOD1G93A motoneurons rather than inducing widespread changes in firing or synaptic transmission. Together, our results provide direct evidence for over-active homeostatic control of motoneuron excitability and support a view of motoneuron dysfunction in ALS as a problem of altered feedback regulation rather than simply hyper- or hypo-excitability.","42353250":"ID: 42353250\nTitle: Microglial Dysfunction Induced by C9ORF72 Dipeptide Repeat Proteins: Biomarker and Therapeutic Perspectives.\nAbstract: The GGGGCC hexanucleotide repeat expansion (HRE) in C9ORF72 was recognized as the most common genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Repeat-associated non-AUG (RAN) translation of the expanded repeat generated dipeptide repeat proteins (DPRs), which disrupted multiple cellular processes and contributed to neurodegeneration. Emerging evidence indicated that disease pathogenesis involved both gain-of-function (GOF) and loss-of-function (LOF) mechanisms. DPR-mediated GOF toxicity induced ribosomal dysfunction, nucleolar stress, proteostatic impairment, and neuronal injury, whereas C9ORF72 LOF disrupted lysosomal and autophagic pathways in microglia, impairing the immune homeostasis. Neuronal injury further promoted the release of damage-associated signals that triggered secondary microglial activations and chronic neuroinflammations. This review summarized current knowledge of DPR biology, microglial dysfunction, and their contributions to disease progression in C9ORF72-associated ALS/FTD. Therapeutic strategies targeting repeated RNA, DPR productions, proteostasis, autophagy, and neuroinflammatory pathways were also discussed. In addition, the potentials of fluid biomarkers, including cerebrospinal fluid poly (GP) and blood neurofilament light chain (NfL), for diagnosis, disease monitoring, and therapeutic assessment were shown. Together, these findings provided important insights into disease mechanisms and potential avenues for improved clinical management.","42360563":"ID: 42360563\nTitle: Characterization of sensory nerve conduction abnormalities at the time of ALS diagnosis.\nAbstract: Although sensory nerve abnormalities have been reported in amyotrophic lateral sclerosis (ALS), their distribution at diagnosis, relative to motor involvement and clinical onset phenotype remains incompletely characterized. We aimed to systematically compare sensory and motor nerve conduction abnormalities at ALS diagnosis and determine whether sensory involvement follows an onset-dependent pattern similar to motor dysfunction. In this prospective cross-sectional study, 40 newly diagnosed ALS patients enrolled in the Iran University ALS Registry (March 2022-March 2023) underwent standardized motor and sensory nerve conduction studies (NCS). For between-group comparisons, a matched ALS subgroup was compared with matched healthy controls, while the expanded ALS cohort was used for subgroup and correlation analyses. SNAP amplitudes of the median, ulnar, and sural nerves were reduced by 45%, 34%, and 43%, respectively, compared with healthy controls, with similar reductions observed across upper- and lower-limb onset phenotypes and no significant onset-dependent differences. In contrast CMAP amplitudes were markedly reduced in ALS patients, most prominently in the peroneal (79%), median (47%), tibial (42%), and ulnar (37%) nerves. Motor abnormalities were most severe in the clinically affected limb but were also detectable in asymptomatic extremities, consistent with early subclinical spread. At ALS diagnosis, sensory and motor nerve conduction abnormalities exhibited divergent spatial patterns, with asymmetric, onset-related motor involvement and relatively uniform sensory axonal dysfunction. These findings support the presence of measurable sensory nerve conduction abnormalities in a subset of ALS patients, while highlighting the need for cautious interpretation of sensory NCS changes in ALS.","42362484":"ID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.","42363684":"ID: 42363684\nTitle: FMRP-Mediated Proteasome Regulation: A Novel Mechanism in ALS Pathology.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a rare and fatal neurodegenerative disease characterized by the hallmark cytoplasmic accumulation and aggregation of TAR DNA binding protein 43 (TDP-43), which impairs proteasome activity through its interaction with Tankyrase (TNKS). Using molecular and imaging techniques, we have identified a novel role for the Fragile X Mental Retardation Protein (FMRP) in regulating the TNKS/PI31-mediated proteasome activation mechanism in co-operation with TDP-43. Our results demonstrate that depletion of FMRP causes nuclear translocation of TDP-43, reducing cytoplasmic TNKS/TDP-43 co-localization, thereby releasing TNKS in the cytoplasm. Free TNKS gets associated with proteasome inhibitor of 31 kDa (PI31), reversing PI31-mediated inhibition of proteasome assembly, trafficking, and activity. Thus, FMRP regulates proteasome activity by modulating the subcellular distribution of TDP-43. Interestingly, FMRP expression is elevated in specific brain regions and spinal cords of TDP-43A315T transgenic ALS mice that helps more TDP-43 to stay in cytoplasm to sequester more TNKS with it, resulting in proteasome dysfunction in ALS disease system. We have demonstrated for the first time that FMRP can act as a disease modifier for ALS. ALS patients with high FMRP expression in the brain and spinal cord may exhibit more severe protein aggregation due to proteasome dysfunction.","42364760":"ID: 42364760\nTitle: The impedance mismatch theory: A non-equilibrium thermodynamic framework for a shared energetic stress pathway in neurodegeneration.\nAbstract: Current neurobiological models of Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's Disease (HD) utilize multi-omic interactome analyses to map cascades of proteinopathy. While essential, these approaches often overlook the macroscopic thermodynamic limits of the neural substrate as an information processing system. We propose the Impedance Mismatch Theory, a theoretical biophysical model and quantitative framework for the thermodynamic limits of neural computation, positing that these distinct pathologies converge as a shared energetic stress pathway. We introduce the Neurophysiological Load Index (NLI)-a dimensionless parameter quantifying the mismatch between electrical computational drive, topological network impedance, and the local structural and microvascular dissipation capacity. Drawing on the Pennes Bioheat Transfer Equation and insights from multiplex network theory, we hypothesize that pathology initiates as localized thermal runaway, where resistive metabolic heat exceeds convective blood perfusion and thermal conduction, inducing acute decompensation. We outline cross-translational disease-network mechanisms, address the inverse cancer comorbidity paradox via speculative bioelectric attractor states, and propose falsifiable predictions involving high-resolution in vivo proton magnetic resonance spectroscopy thermometry (1H-MRS-t) and phosphorus-31 magnetic resonance spectroscopy (31P-MRS).","42365390":"ID: 42365390\nTitle: Lysophagy protects against ANXA11 amyloid fibril toxicity and propagation in FTLD.\nAbstract: Accumulation of Annexin A11 (ANXA11) aggregates is a distinct pathological hallmark of amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD). While genetic studies have linked ANXA11 mutations (e.g., D40G) to disease, the precise molecular events converting aggregation into neurotoxicity and intercellular propagation remain elusive. We hypothesize that lysosomal integrity serves as a critical checkpoint in ANXA11 proteinopathy and that its failure drives disease progression. To model the human pathology of ANXA11, we generated pre-formed fibrils (PFFs) of wild-type and FTLD/ALS-linked D40G mutant ANXA11. Human iPSC-derived neurons, 3D cerebral organoids, and bulk RNA-sequencing were employed to investigate neurotoxicity. High-resolution imaging, lentiviral knockdown, and biochemical assays were performed to delineate the lysosomal damage response and the subsequent \"prion-like\" spreading of aggregates. The internalized ANXA11 fibrils accumulated in lysosomes, triggering lysosomal membrane permeabilization (LMP). The D40G mutation exacerbated this toxicity, leading to severe LMP, mitochondrial depolarization, and specific transcriptional downregulation of the dynactin subunit ACTR10. Mechanistically, we identified a protective signaling axis involving p38 MAPK, MK2, and HSP27 that senses ANXA11-induced lysosomal damage and initiates lysophagy. Notably, in human cerebral organoids, failure of this lysophagic clearance facilitated the cytoplasmic escape of ANXA11, thereby accelerating its seeding activity and propagation to neighboring cells. Pharmacological or genetic modulation of this pathway significantly altered neuronal survival. Our study established lysosomal rupture as a primary driver of ANXA11-associated neurodegeneration and validated the p38/MK2/HSP27 axis as a crucial defense mechanism in human neural tissue. These findings provide a novel mechanistic link between lysosomal quality control and ANXA11 propagation, highlighting that enhancing lysophagic flux represents a promising translational strategy to halt the progression of FTLD and ALS.","42371122":"ID: 42371122\nTitle: Quantification of amyotrophic lateral sclerosis (ALS) disease accumulation with T1-weighted high-resolution magnetic resonance imaging: validation in an independent cohort.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a progressive neuromuscular disease with multifaceted phenotypic presentation thus obstructing objective disease staging. The D50 disease progression model is a framework to comprehensively dissect biomarker-signals towards their relevance regarding disease accumulation/phase (rD50), or disease aggressiveness (D50). Based on previous findings using 1.5-Tesla Magnetic-Resonance-Imaging (MRI), this study hypothesized that high-resolution MRI markers of Grey-Matter (GM) structural integrity would enable quantification of disease accumulation, independent of aggressiveness. A separate cohort of 75 patients with ALS and 73 Healthy Controls (HC) underwent T1-weighted 3-Tesla MRI. Voxel-Based-Morphometry measured GM and White-Matter (WM) density and Surface-Based-Morphometry assessed Cortical Thickness (CT). Non-parametric Threshold-Free-Cluster-Enhancement with 5000 permutations was applied for inter-group and regression contrasts, whilst correcting for possibly interfering co-variates and applying Family-Wise-Error-adjustment. Compared with HC, the ALS cohort showed widespread decreases of CT and GM/WM density (p < 0.001). These case-control effects were driven by patients scanned during rD50-defined disease Phase 2 (p < 0.001). Within the ALS-cohort, direct Phase 2 versus Phase 1 contrasts revealed spatially-distributed decreases, reflecting higher disease accumulation (p < 0.05). These were independent of disease aggressiveness (and onset-region), as corrected for in the models. Accordingly, all contrasts assessing aggressiveness did not yield significant results. These semi-automated analyses of T1-weighted-images captured disease accumulation related GM structural integrity-loss in this cohort scanned with 3-Tesla MRI, independent of the underlying disease aggressiveness. This principle was validated across different scanners and field strengths, supporting its application for objective and non-invasive staging of patients with ALS, whereby true longitudinal studies are necessary.","42373582":"ID: 42373582\nTitle: Unravelling the Significance of Cystatin C and Bunina Bodies in Amyotrophic Lateral Sclerosis Pathogenesis.\nAbstract: Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND), is a fatal neurodegenerative disease primarily affecting motor neurons. Two key protein inclusions found in lower motor neurons serve as neuropathological hallmarks of the disease in human tissue: the TDP43-positive inclusion and the cystatin C-positive Bunina body. Despite their diagnostic specificity and presence in most sporadic and familial ALS cases, Bunina bodies remain poorly understood, and their true prevalence is likely underestimated. The co-occurrence of the Bunina body and the TDP43 inclusion may provide valuable insights into the development of TDP43 pathology in ALS. Thorough characterisation of the Bunina body is needed to understand this interplay and the broader pathomechanisms of disease. This review examines our current knowledge of Bunina bodies and the biochemical properties of cystatin C that may promote its aggregation. Sequestration and aggregation of cystatin C into Bunina bodies may diminish its neuroprotective functions, including cysteine protease inhibition, autophagy induction and anti-amyloidogenic activity, thereby contributing to ALS pathogenesis. This review also evaluates findings from human post-mortem tissue and ALS disease models, discussing the value and limitations of these models in the context of Bunina bodies and TDP43 pathology. Finally, we discuss cystatin C's use as a biomarker and its therapeutic potential. A deeper understanding of cystatin C biology, its relationship with TDP43 pathology and improved ALS models will be essential for determining whether targeting cystatin C could provide a viable avenue for future ALS therapies.","42374626":"ID: 42374626\nTitle: Microbiome and metabolites impact enteric and central nervous systems in ALS.\nAbstract: Amyotrophic lateral sclerosis (ALS) has been linked to gastrointestinal symptoms and alterations in the gut microbiota.

The mechanisms by which luminal changes relay to the central nervous system (CNS), where motor neurons reside, have yet to be completely defined. In this narrative review, we first present evidence from ALS patient cohorts and preclinical models alongside mechanistic studies of infection, dysbiosis, and related neurodegenerative diseases to discuss how the microbiota and its metabolites may affect the ENS and CNS in ALS. Next, we propose a plausible mechanism of ALS pathogenesis through the gut-microbiome-brain axis. We further offer a summary of clinical trials that have studied the impacts of the microbiota on human ALS. Finally, we discuss future directions for studies of microbiota-ENS-CNS interactions in ALS. Better understanding of the dynamic interactions among the microbiota, microbial metabolites, neuroactive metabolites, and inflammation through the ENS/CNS in ALS will provide innovative insights into ALS prevention and treatment.","42375068":"ID: 42375068\nTitle: Distal Motor Latency in Amyotrophic Lateral Sclerosis: A Robust and Reliable Prognostic Marker.\nAbstract: An electrophysiological test is routinely done to confirm Amyotrophic Lateral Sclerosis (ALS) and rule out differentials. Distal Motor Latency (DML) is a simple electrophysiological measure that is always done in a primary setting. It can be used as an excellent prognostic marker for ALS so that we can know ALS better and formulate precise management plans. This longitudinal study was conducted in the Neurology Department of Bangladesh Medical University (BMU), Dhaka, Bangladesh from April 2022 to October 2023. In this study a total of 34 subjects, 17 ALS patients with normal DML and 17 ALS patients with prolonged DML, were enrolled. Severity was assessed by the ALS functional rating scale-revised (ALSFRS-R). The study's endpoints were determined as death during this 6-month follow-up or reaching an advanced stage (ALSFRS-R <20). Then, an electrophysiological test was used to measure DML in all four commonly tested nerves. ALSFRS-R was significantly reduced (p<0.025) at 6 months in ALS patients with prolonged DML than normal DML. It was found that having a higher odd (p<0.012, OR=20.718), prolonged DML had a significant impact on the outcome of ALS patients than that of normal DML. In multivariate analysis, lower ALSFRS-R at diagnosis (B= -0.124, p<0.001, HR=0.883) and prolonged DML (B=1.412, p<0.031, HR=4.104) were associated with poor outcomes. ALS patients with prolonged DML also had a poorer prognosis than patients with normal DML (log-rank test, p<0.045). In this study, patients with prolonged DML had a significant functional decline, rapid disease progression and poor prognosis than patients with normal DML. So, prolonged DML can be used as a robust prognostic marker for patients with ALS.","42381488":"ID: 42381488\nTitle: Neural Organoid Models as a Platform for Studying Disease Mechanisms in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder affecting upper and lower motor neurons leading to muscle wasting. However, structural and molecular abnormalities, including cortical thinning and TDP-43 pathology, extend into frontal, parietal, and temporal areas, pointing to defects across broader cortical regions. The advent of human induced pluripotent stem cell (hiPSC) technology has enabled the generation of human-specific brain cell types in vitro. Here, we provide an overview of the three-dimensional (3D) hiPSC-derived neural organoid platforms used to model cortical structures and to study cortical ALS-associated phenotypes. We review which pathological hallmarks have been recapitulated in these organoids and discuss disease phenotypes reported to date. Further, we comprehensively cover different neural organoid models and experimental strategies, including patient-derived hiPSC models and exogenous pathology induction, while addressing current technical challenges. Together, these advances position neural organoids as an emerging tool to study cell-type-specific and circuit-level mechanisms related to cortical changes in ALS.","42383305":"ID: 42383305\nTitle: TDP-43 proteinopathy as a biomarker and therapeutic target in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is the most common form of adult-onset motor neuron disease, characterised by the degeneration of upper and lower motor neurons. The cytoplasmic aggregation of TDP-43 (TAR DNA-binding protein 43), an RNA-binding protein, is considered a hallmark of ALS pathology, found in nearly all postmortem cases of ALS. TDP-43 is normally primarily nuclear, where it has a widespread role in gene regulation. Mutations, extrinsic stressors, and alterations in RNA homeostasis in ALS lead to nuclear depletion of TDP-43 and the formation of cytosolic TDP-43 aggregates. This causes multiple downstream effects on neuronal function and degeneration as well as gene expression. TDP-43 is a promising target as a biomarker, as it is found to be elevated in the biofluids of ALS patients, and its cytoplasmic aggregation can also be observed in peripheral tissues; however, methodological variability and technical limitations currently preclude the establishment of TDP-43 as a standalone biomarker. There are also promising therapeutic strategies in development targeting TDP-43 pathology, but a critical challenge that remains is achieving a balance between eliminating toxic aggregates and preserving the essential functions of TDP-43. In summary, with further research, considering TDP-43 pathology in ALS gives hope for finding future novel diagnostics and therapeutics for ALS.","42384233":"ID: 42384233\nTitle: Genome-wide spectrum of coding DNA variations in Indian patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with limited therapies, emphasizing the need for deeper understanding of disease pathogenesis. While more than 40 ALS-associated genes have been identified, their contribution varies significantly across populations and the data from the Indian population remains scarce. We aimed to comprehensively characterize the spectrum of coding DNA variations in ALS-associated genes and identify novel genetic contributors in an Indian cohort. Whole-exome sequencing on 761 ALS patients and 917 in-house healthy controls and repeat-primed PCR for expansions (C9orf72, ATXN2, NOTCH2NLC, NOP56) were performed. Variants were classified using ACMG guidelines, and rare variant association testing was conducted. Overall diagnostic yield was 15.90%, with pathogenic/likely pathogenic variants. Familial ALS showed higher diagnostic yield (36.95%) than sporadic ALS (12.96%). SOD1 dominated familial cases (53.85%), while OPTN, SOD1 and FIG4 were prevalent in sporadic cases. Homozygous SOD1 variants in six patients correlated with juvenile/young onset (< 30 years). C9orf72 expansions (4%) and ATXN2 repeats (1.7%) were identified at frequencies comparable with Asian cohorts. Rare variant analysis identified JAK2 as a novel genome-wide significant signal (FDR = 3.5 × 10-5). This first large-scale genomic survey of Indian ALS patients showed SOD1 being the predominant cause of fALS, while OPTN, FIG4, and other genes drive disease amidst low C9orf72 frequency. The novel JAK2 association suggests a potential neuroinflammatory mechanism, highlighting the importance of studying diverse populations to uncover distinct genetic etiologies.","42386657":"ID: 42386657\nTitle: The SQSTM1 L341V Variant Associated With Sporadic ALS Promotes the Accumulation of Enlarged Ubiquitin-Positive SQSTM1 Bodies.\nAbstract: SQSTM1 is one of the causative genes of neurodegenerative disorders, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). The SQSTM1 protein regulates the degradation of polyubiquitinated proteins and autophagosome formation through its interaction with microtubule-associated protein light chain 3 (MAP1LC3/LC3). However, the molecular mechanisms by which SQSTM1-LC3 binding regulates the autophagy-endolysosomal system (APELS) remain unclear. To elucidate the spatiotemporal role of SQSTM1, we transiently expressed wild-type SQSTM1 or missense mutants carrying mutations in the LC3-interacting region (LIR), fused with the photoconvertible fluorescent protein Dendra2. Live-cell fluorescence imaging and co-localization analyses with markers of the APELS were then performed. Particle analysis of photoconverted or non-photoconverted SQSTM1-positive structures in live cells revealed that the pathogenic L341V variant formed larger structures than the wild-type. Co-localization analyses further showed that both the L341V and artificial LIR3A mutants accumulated in large ubiquitin-positive structures, likely due to impaired localization to autophagosomes. These results suggest that mutations within the LIR differentially affect autophagosome formation and cargo degradation within APELS-related compartments, highlighting the importance of SQSTM1 structural integrity in ALS/FTD pathogenesis.","42392979":"ID: 42392979\nTitle: Deletion of exon 2 in ALS-linked Sptlc1 causes lethality in homozygous mice but not in heterozygotes.\nAbstract: Mutations in the human SPTLC1 gene have recently been linked to early-onset amyotrophic lateral sclerosis (ALS), characterized by global atrophy, motor impairments, and symptoms such as tongue fasciculations. All known ALS-linked SPTLC1 mutations cluster within exon 2, and a specific variant, c.58G>T, results in exon 2 skipping. However, it is unclear how the exon 2 deletion affects SPTLC1 function in vivo and contributes to ALS pathogenesis. Leveraging the high genomic sequence similarity between mouse and human SPTLC1, we created a novel knock-in mouse model with a CRISPR/Cas9-mediated deletion of exon 2 in the endogenous murine Sptlc1 locus. Although heterozygous mice did not develop motor defects or ALS-like neuropathology, homozygous mutants died prematurely. These findings provide valuable insights into SPTLC1 exon 2 biology and serve as a useful resource for future mechanistic studies.","42397462":"ID: 42397462\nTitle: A case study of comprehensive association analysis and risk prediction of amyotrophic lateral sclerosis in a Chinese population.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease with significant genetic heterogeneity. While large-scale studies have characterized its genetic architecture in European populations, the genetic basis of ALS in the Chinese population remains under-explored. To address this gap, we conducted a comprehensive genetic analysis on a cohort of 40 Chinese individuals (32 ALS patients and 8 controls) using whole genome sequencing. We employed the Phenotype-Covariate Genetic Correlation method to estimate SNP-based heritability on the liability scale and utilized LDAK-KVIK for gene-based association analysis. Our analysis revealed a SNP-based heritability (h2SNP) of approximately 25.1% in this Chinese cohort, with a positive correlation between minor allele frequency and heritability, highlighting the substantial contribution of common variants. Gene-based analysis prioritized candidate risk genes, including MIB1, TMED2, and DOC2B, which implicate ubiquitin-mediated protein degradation and intracellular vesicle trafficking in ALS pathogenesis. In risk prediction models, the BOLT-LMM approach achieved a robust mean Area Under the Curve (AUC) of 0.883. This study provides the first comprehensive estimate of SNP-based heritability in a sequenced Chinese ALS cohort and supports the \"polygenic background\" hypothesis. The identification of candidate risk genes and the preliminary validation of polygenic risk scoring highlight the potential for future genetic stratification in Chinese patients.","42400730":"ID: 42400730\nTitle: Neuroprotective potential of resveratrol in Parkinson, Huntington, amyotrophic lateral sclerosis, and multiple sclerosis: a comprehensive review.\nAbstract: Resveratrol shows neuroprotective effects in preclinical studies across a number of neurodegenerative illnesses, including Parkinson's disease (PD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), and Huntington's disease (HD), and it enhances mitochondrial function through stimulation of the AMPK/SIRT1/PGC-1α pathway, thereby improving mitochondrial oxidative capacity and ATP generation. The natural polyphenol lowers α-synuclein accumulation and affects autophagy; both markers of PD. Combining nano‑resveratrol formulations with L‑DOPA has shown greater therapeutic efficacy in animal models (MPTP mouse), while co‑administration with EGCG has shown synergistic neuroprotection in vitro (SH‑SY5Y cells). These combination strategies offer potential advantages in neuroprotection and symptom alleviation while minimizing adverse drug effects. Resveratrol activates SIRT1 and AMPK signaling in preclinical models, enhancing mitochondrial biogenesis, lowering apoptosis, and restoring cellular resilience. The effectiveness of various models and dosages varies. The primary mechanism by which resveratrol promotes neuronal survival and remyelination in multiple sclerosis is through SIRT1 activation, which does not directly reduce inflammation. As innovative delivery systems, intranasal nanoparticles and exosomes produced from macrophages have shown improved CNS targeting accuracy. Resveratrol slows down neurodegeneration and improves the prognosis of HD by improving motor function and stimulating mitochondrial biogenesis in addition to activating neuroprotective ERK signaling. All of these results point to resveratrol's several pathways as a strong contender for neurodegenerative disease adjunctive treatment. The current evidence base is insufficient to support clinical use of resveratrol for any of the four diseases. Further rigorous preclinical studies (including TDP-43 models for ALS, SIRT1 knockout studies, and human-feasible dosing) and well-designed clinical trials with pharmacokinetic endpoints are required before any clinical recommendations can be made.","42407013":"ID: 42407013\nTitle: Role of the Upper Motor Neuron in the Generation of Fasciculations in Early Disease Stages of Amyotrophic Lateral Sclerosis.\nAbstract: The origin of fasciculation potentials (FPs) in the early stages of amyotrophic lateral sclerosis (ALS) remains a subject of debate. We investigated the role of the motor cortex in FP generation by comparing resting FP frequency in the first dorsal interosseous (FDI) muscle before and after motor cortex inhibition induced by continuous theta-burst stimulation (cTBS). We studied patients with early-stage ALS (G1) and a disease-control group (G2) comprising individuals with chronic lower motor neuron (LMN) disorders or benign fasciculation syndrome without upper motor neuron (UMN) involvement. Inclusion required a right FDI strength of MRC grade 4+ or 5. At baseline, we recorded FP frequency and amplitude in the right FDI (3 replicates) and the motor evoked potential (MEP) amplitude. These measures were repeated immediately after cTBS-induced corticomotor inhibition. Statistical significance was set at p < 0.05. Twenty-two patients with ALS (14 men; median age 65.5 years; 72.7% spinal onset) were included, with a median disease duration of 6.4 months and a mean ALSFRS-R score of 44. The control group (G2) consisted of 11 participants. Notably, 50% of the ALS cohort showed no neurogenic features on needle EMG of the right FDI at enrollment. Baseline peripheral and cortical amplitudes and left hemisphere motor thresholds were comparable between groups. After cTBS, MEP amplitudes decreased significantly in both G1 (0.93 vs 0.50 mV, p = 0.02) and G2 (1.23 vs 0.38 mV, p = 0.02). However, a significant reduction in FP frequency (39.5%) occurred only in the ALS group (0.43 vs 0.26 Hz, p < 0.001), whereas no change was observed in G2 (0.60 vs 0.77 Hz, p = 0.14). Patients with ALS with a normal FDI EMG demonstrated an even greater reduction in FP frequency (54.5%). FP amplitudes remained stable across both groups after cTBS. Our findings indicate that in early ALS, LMN excitability is significantly modulated by descending corticospinal input. The reduction in FP frequency after cortical inhibition suggests that FPs in early ALS are driven by a combination of both UMN and LMN hyperexcitability, distinguishing them from fasciculations in other neurogenic disorders.","42411482":"ID: 42411482\nTitle: Amyotrophic Lateral Sclerosis as a Systemic Disease: Why Integrative and Microbiome-Focused Approaches Deserve Re-Evaluation.\nAbstract: Despite decades of intensive research, therapeutic advances in amyotrophic lateral sclerosis (ALS) remain limited. Increasing evidence suggests that ALS is a multisystem disorder involving motor neuron degeneration, immune dysregulation, skeletal muscle pathology, and gastrointestinal dysfunction, thereby challenging the adequacy of current therapeutic strategies. Complementary and alternative medicine (CAM) approaches are widely used by patients with ALS. However, their efficacy remains controversial owing to limited clinical evidence and methodological limitations. The multicomponent herbal medicine and system-level characteristics of CAM conceptually align with the emerging view of ALS as a multisystemic disease. The involvement of gut microbiome dysbiosis in the pathophysiology of ALS has provided a unifying biological framework linking the peripheral, metabolic, and neuroinflammatory processes. These findings suggest that the combination of CAM and conventional therapy may serve as a potential integrative approach to target gut-brain-muscle interactions and systemic disease pathways. This article highlights critical gaps in the existing evidence and proposes that microbiome-focused, biomarker-driven clinical trials are essential to thoroughly evaluate CAM-based interventions in ALS. Embracing a system-oriented therapeutic framework may help address the complexity of ALS beyond traditional neuron-centered approaches.","42411953":"ID: 42411953\nTitle: Reduced Soluble Ubiquilin2 in Amyotrophic Lateral Sclerosis Carrying Ubiquilin2 (P494L) Mutation: Clinicopathological and Biochemical Evidence From an Autopsy Case.\nAbstract: We report the clinicopathological and biochemical findings of ALS associated with a UBQLN2 P494L mutation.

Laboratory findings revealed elevated creatine kinase and positive serum human T-cell leukaemia virus type 1 (HTLV-1) antibody. Clinical and electrophysiological findings met revised El Escorial criteria for amyotrophic lateral sclerosis (ALS), but muscle MRI showed inflammatory changes. Muscle biopsy revealed both neurogenic and inflammatory features. While methylprednisolone showed no benefit, intravenous immunoglobulin therapy produced transient improvement in weakness with normalisation of creatine kinase levels. The patient died from respiratory failure 3 years after symptom onset. Autopsy confirmed typical ALS-TDP pathology with phosphorylated TDP-43 inclusions in motor neurons. HTLV-1 Tax-positive lymphocytes infiltrated skeletal muscles but not the central nervous system, establishing dual pathology of ALS-TDP with HTLV-1-associated myositis. The improvement most likely reflected treatment of the HTLV-1-associated myositis rather than the underlying motor neuron disease. This case highlights the importance of evaluating treatable conditions in HTLV-1-seropositive ALS patients.","42418280":"ID: 42418280\nTitle: Phase Separation Drives Pathological Aggregation in Neurodegenerative Diseases: A 15-Year Bibliometric Landscape (2009-2024).\nAbstract: Liquid-liquid phase separation (LLPS), a biophysical driver of membraneless organelle assembly, is central to pathological aggregation in neurodegenerative diseases. Initially linked to amyotrophic lateral sclerosis (ALS), LLPS dysregulation has now been implicated in Alzheimer's, Parkinson's, and frontotemporal dementia, where aberrant transitions convert dynamic condensates into insoluble fibrils. To systematically map this landscape, we employed CiteSpace-based bibliometrics to analyze 784 Web of Science articles from 2009 to 2024. Our analyses reveal dominant contributions from the United States, China, and Germany, with collaborative networks focusing on protein dynamics. Key hotspots include LLPS-driven aggregation of TARDBP (TDP-43), FUS, and α-synuclein, alongside stress granule dysfunction and nucleocytoplasmic transport defects. Emerging frontiers highlight therapeutic strategies targeting pathological condensates utilizing small-molecule chaperones and posttranslational modification modulators to restore cellular homeostasis. Our findings underscore LLPS as a critical axis bridging molecular pathology and translational innovation. The field is rapidly shifting from mechanistic exploration to therapeutic applications, emphasizing interventions to halt or reverse aggregation. By delineating global trends and changing priorities, our study highlights the transformative potential of phase-targeted interventions and provides a roadmap of groundbreaking interdisciplinary research into neurodegenerative disorders.","42419740":"ID: 42419740\nTitle: TOP1MT rs2293925 is an enhancer-active regulatory SNP that shapes mitochondrial R-loop dynamics.\nAbstract: Mitochondrial topoisomerase 1 (TOP1MT) regulates mitochondrial DNA (mtDNA) topology during transcription and replication. Perturbed mtDNA maintenance and RNA metabolism have been implicated in neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS). Here we show that the common TOP1MT variant rs2293925 (R525W) has enhancer-like activity and is associated with increased mitochondrial R-loops (RNA : DNA hybrids). Tissue-dependent expression, quantitative trait locus analysis, chromatin-state annotation, reporter assays, and allele-specific DNA-protein binding assays support a transcriptional regulatory role for rs2293925. In isogenic cell models, rs2293925 increased TOP1MT mRNA and protein abundance, and this was accompanied by increased mitochondrial R-loop signal. TOP1MT trapping with lamellarin D supported increased TOP1MT-R525W occupancy at mitochondrial control region sites together with enhanced R-loops, consistent with altered TOP1MT-mtDNA interaction and/or increased TOP1MT abundance. Elevated mitochondrial R-loop signal was also detected in a pilot cohort of sporadic ALS samples carrying rs2293925 and in neural stem cells derived from C9orf72-positive ALS patients. These data support a dual-effect model in which rs2293925 increases TOP1MT expression and is associated with altered mitochondrial R-loop dynamics, linking common genetic variation to mitochondrial nucleic acid stress in disease-relevant contexts.","42420060":"ID: 42420060\nTitle: Development of a target product profile for artificial intelligence in diabetic eye screening in England: a modified Delphi consensus study.\nAbstract: Artificial intelligence (AI) health-care technologies offer a means of addressing the growing gap between health-care capacity and demand. However, few technologies have met the complex requirements of health-care systems for adoption. Diabetic eye screening (DES) in England exemplifies the difficulty of understanding these requirements and translating them into real-world implementation decisions. This Review responds to a recognised policy need to develop a target product profile (TPP) for a DES AI system for use in England. The TPP outlines the requirements of the English health-care system for such a device and was developed using a modified Delphi consensus process involving interviews, surveys, and a consensus meeting. Participants included people living with diabetes, health-care professionals, health-care managers and leaders, regulators and policy makers, and developers. Thirty-five product specifications were agreed upon, covering areas such as clinical validity, utility, and environmental sustainability. Our TPP establishes clear criteria for DES AI development and deployment in England, and this TPP development process can serve as a template for initiatives to create TPPs for other AI health technologies and settings.","42424572":"ID: 42424572\nTitle: Comprehensive Care Goals in Myasthenia Gravis: Expert Consensus Recommendations Using the RAND/UCLA Appropriateness Method.\nAbstract: Goals for comprehensive care are important in the management of individualized treatment for patients with myasthenia gravis (MG), a disease with variable presentation and degrees of severity. Yet there is limited guidance on how comprehensive care should be achieved and implemented. We present global consensus recommendations for comprehensive care of patients with MG. An international panel of experts was formed, and a targeted literature review was conducted to inform the recommendations. A steering committee selected relevant topics and draft recommendations were developed for each topic. Formal consensus was achieved using the RAND/UCLA appropriateness method. Seventeen panelists from North America, Europe, and Asia rated statements online from 1 (\"extremely inappropriate\") to 9 (\"extremely appropriate\") and provided comments and suggestions for modifications. The methodologist modified statements for further rating, based on panel scores and feedback. Statements achieving agreement as appropriate by 4 rounds of rating were accepted. Consensus was achieved for 21 statements. Statement 1 defined the ongoing treatment goal: \"to work toward, achieve, and sustain minimal symptoms and treatment-related adverse events, with a patient-acceptable quality of life (using validated measures)\". Subsequent statements described implementation of this goal and covered: early control of symptoms; establishing and sustaining a treatment goal; vaccination and screening for infection; family planning/pregnancy; management of fatigue and comorbidities; and management of impending crisis and crisis. Expert consensus was achieved on a series of global recommendations for comprehensive care goals, which has implications for improved disease outcomes and health-related quality of life for patients with MG.

With an atypical symptom course consisting of resolved and recurrent weakness of her left leg, the patient had multi-level chronic, evolving spinal-column damage, severe weight loss, newly discovered rectal neoplasm and longstanding psychiatric pathology. With symptoms concerning for both medical and psychosomatic explanations, several potentially compounded aetiologies were considered.

This study aimed to determine whether integrating an ECPR protocol into prehospital cardiac arrest care affects the quality of resuscitation compared to application of the standard Advanced Life Support (ALS) protocol. A randomized controlled simulation study was conducted at the University Hospital Leuven in Belgium using standardized pre-hospital cardiac arrest scenarios. Participants, who were physicians functioning as part of resuscitation teams, were randomized into intervention and control groups. The study included a pre- and post-intervention phase. In the pre-phase, all participants followed the standard ALS protocol. Only the intervention group received training in the additional ECPR protocol between the phases. In the post-phase, the intervention group combined this protocol with standard ALS, whereas the control group continued with ALS alone. The primary outcome was overall resuscitation quality, which was assessed using the modified Peltonen score. The secondary outcomes included occurrence and timing of critical resuscitation actions. A total of 40 physicians participated in the study. Resuscitation quality was not affected by the ECPR protocol; the modified Peltonen score showed no difference in the pre-post change between the groups (0.02, CI: -0.15; 0.19, p = 0.83). However, secondary outcomes showed delayed actions related to the identification and management of the presumed cause of cardiac arrest in the intervention group, such as significantly later verbal suggestions to initiate causal treatments including PCI or thrombolysis. In this simulation study, combining a prehospital ECPR protocol with standard ALS resulted in resuscitation performance comparable to ALS alone. Nonetheless, the protocol was associated with delayed diagnostic and therapeutic actions concerning the reversible causes of cardiac arrest, highlighting the need for ECPR training that integrates diagnostic and therapeutic vigilance with procedural execution.

The core protocol integrates temporary bilateral uterine artery occlusion (simple ligation of the main trunk with No. 1 absorbable Vicryl suture at 2 cm from the uterine wall) immediately before resection, adhesiolysis, en bloc excision of the ectopic mass with a 0.3 cm safe margin, and multilayer anatomical uterine repair. This technique addresses the key clinical challenge of massive intraoperative bleeding in highly vascular type IIIb CSP, with innovations in precise timing of occlusion and reversible minimally invasive ligation. Perioperative outcomes demonstrated excellent hemostasis (total blood loss 100 mL), complete lesion removal confirmed by frozen section, and intact uterine anatomy post-surgery. The study emphasizes the technique's value in hemorrhage control, anatomical restoration, and fertility preservation for patients with large type IIIb CSP (66 mm in this case). We provide a detailed step-by-step surgical guide, clarify patient selection criteria and contraindications, and discuss the technique's advantages, limitations, and potential to revise the standard of care for type III CSP. Postoperative 18-month follow-up showed successful natural conception and uncomplicated second-trimester pregnancy, validating its long-term fertility benefits.","42429841":"ID: 42429841\nTitle: Re: Effects of resistance training with/without photobiomodulation on muscle and respiratory function in difficult-to-control asthma: a randomized trial.\nAbstract: This letter discusses Costa et al.'s randomized trial of resistance training (RT) combined with photobiomodulation therapy (PBMT) for difficult-to-control asthma (DTCA). The triple-blind study shows RT+PBMT safely improves peripheral muscle strength and exercise capacity better than RT alone. PBMT has dose-dependent effects, but optimal parameters for chronic respiratory patients remain unclear. Some clinicians have proposed standalone PBMT for DTCA patients unable to complete resistance training, but this approach has not been validated in clinical trials. The absence of a PBMT-only group limits assessment for patients unable to tolerate RT. The intervention did not improve lung function or asthma control, acting only peripherally. RT+PBMT is a useful adjuvant therapy; future studies should optimize PBMT dosing, test standalone PBMT, and examine long-term outcomes, and compare different PBMT wavelengths, energy settings and irradiation sites to refine real-world treatment protocols.","42429860":"ID: 42429860\nTitle: Human iPSC-Derived Spinal Neurons Carrying the ALS FUS (P525L) Mutation Exhibit Lower Response to Inhibitory Neurotransmitters.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disorder characterized by motoneurons degeneration. Functional studies have linked ALS to hyperexcitability and excitotoxicity, but the cause of the disease is unknown, though familial ALS cases are linked to pathogenic variants in several genes, including SOD1, TARDBP and FUS. Here we focused on the effect of the severe FUS (P525L) mutation on the functional properties of human spinal neurons derived from induced pluripotent stem cells (hiPSCs). This mutation delayed functional maturation, as revealed by the observation that mutated neurons showed alterations of membrane potential, reduced spontaneous synaptic activity, and altered action potentials at early differentiation stages. FUS (P525L) mutation was associated with a significant alteration of inhibitory signalling transmission: mutated neurons showed a significantly lower current response to GABA and glycine compared to control isogenic WT neurons of the same age. Also, glutamatergic currents exhibited a different temporal evolution in control and mutated neurons, but at a lower extent in comparison to inhibitory neurotransmitters. The decrease in the glycine-evoked currents was confirmed by the reduction of the expression of the α1 subunit of glycine receptor, measured by immunofluorescence assay. Similar functional alterations were measured in spinal neurons differentiated form a second hiPSC line, confirming the causative role of the FUS (P525L) mutation. Our data indicate that the FUS (P525L) mutation reduces the maturation rates and the function of hiPSC-derived spinal neurons, with a strong decrease of inhibitory transmission, which may affect the excitatory/inhibitory balance, possibly predisposing to excitotoxicity and neurodegeneration.","42429931":"ID: 42429931\nTitle: [Medial patellofemoral ligament duplication and lateral lengthening plasty ('soft tissue balancing') according to Urs W.

Her medical history included hypothyroidism, psoriasis, and type 2 diabetes. Fundus examination revealed choroidal folds, an amelanotic lesion temporal to the fovea, and an exudative retinal detachment. Optical coherence tomography (OCT) demonstrated a choroidal mass without subretinal fluid, while indocyanine green angiography (ICGA) showed a hypocyanescent lesion with no intrinsic vascularity. B-scan ultrasonography revealed an inhomogeneous choroidal mass with retrobulbar fluid (positive T-sign). Blood tests revealed elevated C-reactive protein (CRP) and liver enzymes levels, together with positive antinuclear antibodies (ANA), while the chest X-ray was normal. The overall clinical and imaging findings were consistent with nodular granulomatous scleritis. Choroidal melanoma, uveal lymphoma, primary vitreoretinal lymphoma, and choroidal hemangioma were excluded based on their imaging characteristics. Treatment with systemic corticosteroids resulted in rapid visual improvement and complete resolution of the lesion. This case demonstrates how inflammatory choroidal lesions can mimic intraocular tumors. Recognizing characteristic multimodal imaging features (choroidal folds, preserved choroidal vasculature on ICGA, positive T-sign on ultrasonography) can enable a confident diagnosis without biopsy, avoiding unnecessary treatment and delays in cancer diagnosis. Eine 59-jährige Patientin stellte sich mit seit vier Monaten progredienter Visusminderung und Mouches volantes am linken Auge vor, ohne Augenbewegungsschmerzen oder Gelenkbeschwerden. Anamnestisch bestanden Hypothyreose, Psoriasis und Diabetes mellitus Typ II. Funduskopisch zeigten sich am linken Auge Aderhautfalten, eine amelanotische, temporal der Fovea gelegene Läsion sowie eine exsudative Ablatio retinae. Die optische Kohärenztomographie (OCT) zeigte eine choroidale Raumforderung ohne subretinale Exsudation, die Indocyaningrünangiographie (ICGA) eine hypocyaneszente, gefäßfreie Läsion. Sonographisch fand sich eine inhomogene Raumforderung mit retroskleraler Flüssigkeit (positives T-Zeichen). Laborchemisch bestanden ein erhöhtes C-reaktives Protein (CRP), erhöhte Leberwerte und positive antinukleäre Antikörper (ANA). Der Röntgen-Thorax war unauffällig. Diese Befunde stützten die Verdachtsdiagnose einer nodulären granulomatösen Skleritis. Differentialdiagnostisch wurden Aderhautmelanom, uveales Lymphom, primäres vitreoretinales Lymphom und chorioidales Hämangiom erwogen. Unter Kortisontherapie mit Prednisolon zeigten sich rasche Visusbesserung und vollständige, stabile Rückbildung der Läsion. Der Fall verdeutlicht, dass die Abgrenzung entzündlicher von neoplastischen intraokularen Raumforderungen zu den schwierigsten Situationen der Ophthalmoonkologie zählt und klinische Erfahrung sowie konsequente multimodale Bildgebung erfordert, um Übertherapie und Verzögerungen der Tumordiagnostik zu vermeiden. Das Vorliegen von wichtigen Befunden in der multimodalen Diagnostik (Aderhautfalten, normalen Aderhautgefäßen in der ICGA, T-Zeichen im Ultraschall) können die korrekte nicht-invasive differentialdiagnostische Einordnung ermöglichen.","42430317":"ID: 42430317\nTitle: Preliminary Investigation of Myoelectric Control of an Assistive Neck Exoskeleton by Individuals with Amyotrophic Lateral Sclerosis.\nAbstract: Neck weakness limits head control and quality of life for individuals with Amyotrophic Lateral Sclerosis (ALS). The Utah Neck Exoskeleton can restore neck motion, but current control methods-joystick and gaze tracking-have limited accessibility and reliability. These preliminary offline analyses investigate neck electromyography (EMG) as an alternative control modality from ALS patients. EMG signals were recorded from four male participants with ALS while performing neck flexion/extension, axial rotation, and lateral deviation. The resulting dataset was used to train convolutional neural networks (CNNs) per patient to classify either head position or movement direction from EMG features offline. Position classification significantly outperformed direction classification, with a mean accuracy of 82.5% ± 0.010 across participants. Performance was consistent when controlling one, two, or all three neck degrees of freedom. A subset of participants with sufficient residual motor function also completed neck movements while talking or chewing. Classification accuracy decreased during talking and chewing, although these effects were not statistically significant. Importantly however, training CNNs with diverse data that included periods of talking and chewing improved algorithm robustness across all conditions. These findings suggest that neck EMG signals can reliably predict intended head movements in ALS, even in the presence of weak and often confounding muscle activity. Offline accuracy and real-time computational speed suggest the approach is feasible for future online user-in-the-loop studies. Altogether, this pilot work advances EMG-based assistive technology for individuals with severe motor impairments, laying the groundwork for clinically viable, intuitive control systems.","42430680":"ID: 42430680\nTitle: Neurology® Journal Club: Duration of Current Statin Use and Amyotrophic Lateral Sclerosis Risk.\nAbstract: This article critically appraises the study by Nakken et al., \"Duration of Current Statin Use and Amyotrophic Lateral Sclerosis (ALS) Risk.\" Previous observational studies and Mendelian randomization studies examining statin use and ALS risk have reported mixed results. Millions of adults receive statins for cardiovascular prevention and may be concerned when neuromuscular symptoms suggestive of ALS appear. Using linked nationwide health survey and prescription data, this Norwegian population-based cohort study applied time-dependent models to evaluate statin use and subsequent ALS risk. Short-term statin use was associated with increased ALS risk, whereas long-term use was associated with lower risk. The authors interpreted this as evidence of reverse causation rather than a causal or protective effect of statins. Key strengths of the study include its large population-based design, the use of a negative control, and time-dependent Cox modeling. However, limitations inherent to observational study designs and potential residual confounding should be considered. In this article, we summarize the findings, highlight key statistical concepts, and discuss the study's major strengths and limitations.","42431020":"ID: 42431020\nTitle: Clinical studies in 82 individuals with valosin-containing protein (VCP) associated multisystem proteinopathy and literature review.\nAbstract: Valosin-containing protein (VCP) pathogenic variants cause a multisystem proteinopathy characterized by myopathy, Paget disease of bone, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS). We evaluated 82 affected individuals, 14 presymptomatic carriers, and 36 unaffected first-degree relatives from 48 families to identify sensitive measures for disease monitoring. Mean age of onset was ∼42 years for myopathy, Paget disease, or ALS, and 53 years for dementia. Functional assessments included the Inclusion Body Myositis Functional Rating Scale (IBMFRS), ALSFRS-R, Fatigue Severity Scale (FSS), and six-minute walk test (6MWT). Affected individuals demonstrated progressive functional decline, with IBMFRS decreasing 1.9% annually, FSS increasing 4.4%, and 6MWT decreasing 6% annually when modeled against disease duration. Women declined more rapidly on IBMFRS but showed slower ambulatory and fatigue progression. Potential genotype-specific effects were observed, with earlier onset and shorter survival in p.Arg155Cys compared to later onset in p.Arg155His. Strong correlations among IBMFRS, FSS, and 6MWT indicate these as accessible endpoints for longitudinal monitoring and clinical trials. Rapid decline with ALS and dementia necessitates multidisciplinary support, while longer survival after myopathy or Paget onset offers a window for preventive and supportive interventions.","42432003":"ID: 42432003\nTitle: Compound muscle action potential scan dataset in adults with spinal cord injury and healthy controls.\nAbstract: Certain neurological conditions, such as amyotrophic lateral sclerosis (ALS) and spinal cord injury (SCI), result in motor unit loss in muscles. The stimulus-evoked compound muscle action potential (CMAP) scan captures comprehensive information on motor unit recruitment that enables rapid and non-invasive assessment of motor unit status. However, few publicly available CMAP scan datasets exist to support research on motor unit number estimation (MUNE). To address this gap, we collected CMAP scan data from the first dorsal interosseous (FDI) muscle of 13 individuals with SCI and 13 healthy participants, and established a dedicated CMAP scan dataset. The dataset includes CMAP waveforms evoked by each nerve stimulus from which CMAP scan curve and typical parameters were extracted for direct use. All SCI participants underwent multiple clinical assessments and exhibited a spectrum of impairment severity from mild to severe, resulting in diverse CMAP features. We anticipate that this dataset will facilitate the development of advanced CMAP scan-based assessment techniques and aid in the investigation of neuromuscular impairment.","42432439":"ID: 42432439\nTitle: \"An Injurious and Utterly Unfit Environment\": A Case Study Comparing Dental Evidence of Childhood Stress in Nineteenth Century Working-Class Peoples From British and Colonial New Zealand Contexts.\nAbstract: During the nineteenth century, the health and living conditions of many working-class European peoples declined in association with growing industrialization and urbanization. Emigration to British colonies grew as people sought to escape such hardships. This research presents the first direct comparison of dental markers of stress in a case study of migrants to a British colony (Otago, New Zealand) alongside a contemporaneous assemblage representing an origin population (London, United Kingdom). Dental markers of childhood stress, accentuated lines, were observed in thin-sections of archeological teeth from adults (n = 9) and children (n = 16) interred in London, United Kingdom (UK), and adult European migrants interred in Otago, New Zealand (NZ) (n = 24) using standard histological techniques. All individuals interred in London, and 92% (22/24) of those in New Zealand exhibited evidence of accentuated line formation within the first 2.5 years of life. There was no difference in median accentuated line occurrence between adults and children interred in the UK. However, NZ adults had a lower median occurrence of accentuated lines over the first 2.5 years since birth (5 ALs/individual) than UK adults (13 ALs/individual). Accentuated lines most frequently occurred in infancy for all three groups examined. However, temporal trends in accentuated line occurrence differed between groups in association with age. These results highlight the impact of childhood stresses on working-class people growing up during the nineteenth century, underlining potential differences in the childhood experiences of hardship in individuals that remained in Britain and those that departed for foreign soils.","42432671":"ID: 42432671\nTitle: The role of AI-assisted drug repurposing in neurological disorders: a systematic review of validation strategies, challenges and opportunities.\nAbstract: Neurological disorders refer to a diverse group of conditions that affect the brain, peripheral nerves, and spinal cord and impair socioemotional, cognitive, motor, and sensory functions. Alzheimer's disease (AD), Multiple Sclerosis (MS), Parkinson's disease (PD), Huntington's disease (HD), and Amyotrophic Lateral Sclerosis (ALS) are some of the well-known neurodegenerative diseases that affect millions of people worldwide. Despite the advanced technologies and nano-drug delivery systems, the success rate of developing drugs for neurological disorders is significantly low. Among several constraints, including gastrointestinal irritation, rapid metabolism, and low stability, the blood-brain barrier (BBB) emerges as one of the key challenges in the development and application of drugs against neurological disorders. These challenges necessitate innovative approaches to develop cost-effective therapeutic strategies. Drug repurposing, the discovery of new therapeutic benefits of existing drugs, is a promising drug discovery approach for discovering potential treatment options for complex neurological disorders. This review aims to explore the advanced and significant progress in drug repurposing for major neurological disorders, including MS, AD, PD, ALS, HD, stroke, and neuropsychiatric conditions. It places an explicit emphasis on discussing the potential role of artificial intelligence (AI)-assisted drug repurposing and understanding of the biological mechanisms in discovering new drugs for these neurological conditions. This also examines current challenges in drug repurposing and provides a critical review of the available opportunities and limitations in AI-assisted drug repurposing.","42432946":"ID: 42432946\nTitle: A simulation study on optimizing stationary camera locations for physician-directed telemedical supervision of prehospital advanced life support: Single-versus dual-camera setups.\nAbstract: Prehospital telemedicine, particularly real-time video conferencing, offers significant benefits in prehospital and disaster settings by enabling rapid data transmission. Using a smartphone mounted on a tripod as a stationary camera provides stable footage, comprehensive scene evaluation, and reduced technical complexity, thus complementing smart glasses and built-in cameras. However, the optimal camera location for visualizing key procedures remains unexplored. This study aims to compare the optimal stationary camera location and the effectiveness of single-camera versus dual-camera setups in visualizing key procedures for physician-directed telemedical supervision of prehospital advanced life support (ALS). This prospective, non-randomized simulation study involved 9 advanced emergency medical technicians performing ALS procedures in 20 simulations. Each simulation was recorded simultaneously from 4 stationary camera locations: right head, left head, right leg, and left leg. Reviewers evaluated the visibility of 6 key procedures (airway management, breathing support, chest compressions, intravenous access, electrocardiogram rhythm monitoring, and teamwork) using a 1 to 5 scale. Mixed models and generalized linear mixed models were applied to analyze the visibility scores and compare the effect sizes of the different camera setups. The median visibility scores and proportion of optimal visibility (scores of 4-5) varied significantly across the 4 camera locations for most procedures. However, the mixed model and generalized linear model analyses for overall visibility did not reveal significant differences in effect sizes between individual camera locations. Dual-camera setups showed significant improvement over single-camera setups, with an adjusted odds ratio of 4.89 (95% confidence interval: 1.92-12.4) for the right head + left head combination and 3.74 (95% confidence interval: 1.50-9.32) for the right head + left leg combination. Although no single-camera location provided optimal visualization for all procedures, dual-camera setups were more effective than single cameras in capturing field activity. These findings support the use of dual-camera setups to enhance physician-directed telemedical supervision of prehospital ALS, with potential applicability to disaster settings, and may inform the development of future protocols for prehospital telemedicine.","42434198":"ID: 42434198\nTitle: Quantifying motor unit loss prior to functional impairment in muscles affected by amyotrophic lateral sclerosis.\nAbstract: The compound muscle action potential (CMAP) scan is a non-invasive method for deriving motor unit number estimates (MUNE) to track disease progression in muscles affected by amyotrophic lateral sclerosis (ALS). It remains to be established whether and how long motor unit loss precedes functional impairment. In 56 patients with ALS, we compared the longitudinal trajectories of MUNE derived from thenar CMAP scans, and fine motor function (FMF) using a functional rating scale. Linear and sigmoidal disease trajectories were modelled from which time differences were estimated between these measures to reach their half-maximum scores. The normalized linear decline per month was 0.02 (95% CI 0.01 to 0.03) for FMF and 0.03 (95% CI 0.03 to 0.04) for MUNE. Half-maximum of FMF was reached after 26.3 months (95% CI 18.9 to 35.1) for the linear model, while MUNE had a shorter time required to reach 50% of its maximum with 13.0 months (95% CI 10.3 to 16.4). The head-to-head comparison between FMF and MUNE showed that MUNE values reached 50% of its maximum 13.1 months (95% CI 7.0-20.8) earlier. Results were similar for sigmoidal disease trajectories. Simulated disease trajectories of MUNE values derived from CMAP scans in muscles affected by ALS indicated that MUNE may reach 50% of its maximum in approximately 60% of the time compared to functional impairment. These explorative findings underscore how neurophysiological measures may be of use for early disease monitoring, with relevance for both care and research settings.","42435104":"ID: 42435104\nTitle: Deterministic selection and compositional turnover in Parkinson's disease-associated gut dysbiosis.\nAbstract: The scientific understanding of links between Parkinson's disease (PD) and gut microbiome dysbiosis has advanced significantly, yet the ecological mechanisms driving these microbial changes remain poorly understood. To address this gap, we postulated that PD-associated gut dysbiosis arises as harmful microbes outcompete beneficial bacteria, and consequently any therapeutic strategies must both suppress opportunistic pathogens and restore protective, fiber-degrading microbes to effectively rebalance the gut microbiome in PD. To evaluate ecological patterns consistent with this hypothesis, we apply Sloan's near-neutral model (SNM), Ning et al.'s stochasticity framework, and ecological network analysis to reanalyze six published gut microbiome datasets (1957 samples total: 804 healthy controls, 1153 PD cases). We first applied SNM to categorize bacterial species as neutral, positively selected, or negatively selected. While the overall proportions of these categories were similar between groups (neutral: ~ 40%, positively selected: ~ 47%, negatively selected: ~ 13%), stochasticity framework analysis revealed significantly stronger deterministic selection in PD microbiomes. Shared species analysis (SSA) resolved this apparent paradox by demonstrating substantial compositional shifts within each species category, indicating that while classification frequencies remained stable, the specific microbes occupying these ecological niches changed significantly in PD. This divergence between SNM category proportions and NSR values highlights a subtle yet critical aspect of community assembly dynamics. Ecological network analysis further revealed that neutral species had fewer antagonistic co-occurrence links, consistent with their ecological equivalence, while negatively selected species maintained higher relative abundances in both groups. Together, these findings indicate that PD-associated gut microbiomes are characterized by stronger deterministic assembly signatures and substantial compositional turnover within near-neutral ecological categories. These patterns are consistent with altered ecological assembly signatures in PD-associated dysbiosis.","42436431":"ID: 42436431\nTitle: \"Straddling two worlds\": complexities of spousal caregiving in amyotrophic lateral sclerosis during younger middle age.\nAbstract: Family support is central to amyotrophic lateral sclerosis (ALS) care. Spouses often assume the role of primary caregiver, facing daily challenges as their partner's needs progressively increase. Younger ALS caregivers appear to have distinct experiences and needs, yet age- or life-stage variations and processes of caregiving are seldom considered in studies of ALS family caregiver experience. We undertook a qualitative study, guided by constructivist grounded theory methodology, to explore the dynamics of family caregiving following an ALS diagnosis in a younger middle-aged family member (≤55 years). Data were coded to identify psychosocial processes, including how family caregivers engage in caregiving. In-depth interviews were conducted with ten spousal caregivers between August 2023 and August 2025. Overall, our theoretical understanding of spousal caregiving for younger middle-aged adults with ALS (YMAs) was captured by the core category 'straddling two worlds,' reflecting how caregivers navigated multiple interconnected dichotomies: present and future, familiar and new norms, current and anticipated losses, and the worlds of the living and the dying. To contend with an uncertain future, caregivers anchored themselves in the present as they navigated a shifting sense of normalcy. Middle age expectations and social norms shaped how caregivers engaged in caregiving and experienced losses that were often unending and ambiguous. Caregiving for a spouse with ALS in younger middle age involves temporal, practical, emotional, and existential processes. Caregivers of YMAs may benefit from interventions that help them tolerate uncertainty, stay grounded in the present, maintain normalcy, and grieve losses throughout the caregiving trajectory.","42439916":"ID: 42439916\nTitle: [Cross-linking treatment of ultrathin corneas: the ELZA-sub400 protocol : Individualized adaptation of fluence as paradigm shift in CXL treatment of thin corneal conditions].\nAbstract: The Dresden corneal cross-linking (CXL) protocol requires a minimum corneal thickness of 400 µm to protect the endothelium from UV (ultraviolet) damage; however, many patients with advanced corneal ectatic disease have thinner corneas and are excluded from treatment. Earlier approaches to circumvent this limitation, hypo-osmolar swelling, contact lens-assisted CXL, epithelial island techniques, showed relevant shortcomings. The ELZA-sub400 protocol takes a fundamentally different approach: the UV fluence is individually adapted to pachymetry. This narrative review is based on current literature and clinical experience data from the ELZA Institute. The photochemical principles, the algorithm of the sub400 protocol, clinical outcomes and practical implementation are presented. The sub400 protocol is based on an algorithm integrating Fick's law of diffusion for riboflavin and oxygen and the Lambert-Beer law for UV absorption. By individually adjusting the duration of UV irradiation to the pachymetrically measured stromal thickness, effective cross-linking is achieved while maintaining a 70 µm safety margin above the endothelium. A prospective study of 39 eyes (corneal thickness 214-398 µm) demonstrated a 90% success rate with no signs of endothelial decompensation. The protocol has also been applied in keratoglobus (1 case; tomographic stabilization at 32 months, no endothelial decompensation) [4]. The ELZA-sub400 protocol enables safe CXL even in corneas well below 400 µm thick for the first time. It adapts the technique to the individual anatomy rather than adapting the anatomy to the technique. Implementation requires only ultrasound pachymetry and a 3 mW/cm2 UV light source and is therefore feasible on most available CXL devices. HINTERGRUND: Das korneale Crosslinking (CXL) nach dem Dresden-Protokoll setzt eine minimale Hornhautdicke von 400 µm voraus, um das Endothel vor UV(ultraviolett)-Schäden zu schützen. Viele Patienten mit fortgeschrittener kornealer Ektasie weisen jedoch dünnere Hornhautzustände auf und werden von der Behandlung ausgeschlossen. Frühere Ansätze zur Umgehung dieser Limitation – hypoosmolare Quellung, kontaktlinsengestützte Verfahren – zeigten relevante Einschränkungen. Das ELZA-sub400-Protokoll verfolgt einen grundlegend anderen Ansatz: Die UV-Fluenz wird individuell an die Pachymetrie angepasst. Die Übersichtsarbeit basiert auf aktueller Literatur und aktuellen klinischen Daten des ELZA Institute. Dargestellt werden die photochemischen Grundlagen, der Algorithmus des sub400-Protokolls, klinische Ergebnisse und die praktische Durchführung. Das sub400-Protokoll basiert auf einem Algorithmus, der das Fick-Diffusionsgesetz für Riboflavin und Sauerstoff sowie das Lambert-Beer-Gesetz für die UV-Absorption integriert. Durch individuelle Anpassung der UV-Bestrahlungsdauer an die pachymetrisch gemessene Stromadicke wird ein effektives Crosslinking erzielt und gleichzeitig ein 70-µm-Sicherheitsabstand zum Endothel gewährleistet. In einer ersten prospektiven Studie mit 39 Augen (Hornhautdicke 214–398 µm) und Folgestudien wurde eine Erfolgsrate von 90 % ohne Zeichen einer Endotheldekompensation erreicht. Das Protokoll wurde auch beim Keratoglobus angewandt (1 Fall; tomographische Stabilisierung nach 32 Monaten, keine Endotheldekompensation) [4]. Das ELZA-sub400-Protokoll ermöglicht erstmals ein sicheres CXL auch bei Hornhautzuständen deutlich unter 400 µm. Es passt die Technik an die individuelle Anatomie an, anstatt die Anatomie an die Technik anzupassen. Der Einsatz erfordert lediglich eine Ultraschallpachymetrie und eine 3‑mW/cm2-UV-Lichtquelle und ist damit auf den meisten verfügbaren CXL-Geräten durchführbar."},"globalTags":{"alzheimer’s
