Recent association studies in multiple sclerosis (MS) have identified and replicated several single nucleotide polymorphism (SNP) susceptibility loci including CLEC16A, IL2RA, IL7R, RPL5, CD58, CD40 and chromosome 12q13-14 in addition to the well established allele HLA-DR15. There is potential that these genetic susceptibility factors could also modulate MS disease severity, as demonstrated previously for the MS risk allele HLA-DR15. We investigated this hypothesis in a cohort of 1006 well characterised MS patients from South-Eastern Australia. We tested the MS-associated SNPs for association with five measures of disease severity incorporating disability, age of onset, cognition and brain atrophy. We observed trends towards association between the RPL5 risk SNP and time between first demyelinating event and relapse, and between the CD40 risk SNP and symbol digit test score. No associations were significant after correction for multiple testing. We found no evidence for the hypothesis that these new MS disease risk-associated SNPs influence disease severity.

December 2024

Department of Neurosciences, Hengyang Medical School, University of South China, Hengyang, 421009, China.

Background: Neurological complications are a significant concern of Coronavirus Disease 2019 (COVID-19). However, the pathogenic mechanism of neurological symptoms associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is poorly understood.

Methods: We used Drosophila as a model to systematically analyze SARS-CoV-2 genes encoding structural and accessory proteins and identified the membrane protein (M) that disrupted mitochondrial functions in vivo.

Altered Nigral Amide Proton Transfer Imaging Signal Concordant With Motor Asymmetry in Parkinson's Disease: A Multipool CEST MRI Study.

NMR Biomed

February 2025

Department of Radiology, Beijing Hospital, National Center of Gerontology, Institute of Geriatric Medicine, Chinese Academy of Medical Sciences, Beijing, China.

Asymmetry is a natural characteristic of Parkinson's disease (PD), which can be used to distinguish PD from atypical parkinsonism. Chemical exchange saturation transfer (CEST) has demonstrated value in reflecting the subtle changes related to neuron loss and abnormal protein accumulation in PD but has not been used to investigate asymmetry in PD. This study aimed to examine asymmetrical changes in the mesencephalic nucleus of PD patients with motor asymmetry using four-pool CEST analysis and to explore the relationship between imaging asymmetry and motor asymmetry.

Background: Angelman syndrome (AS), a severe neurodevelopmental disorder resulting from the loss of the maternal UBE3A gene, is marked by changes in the brain's white matter (WM). The extent of WM abnormalities seems to correlate with the severity of clinical symptoms, but these deficits are still poorly characterized or understood. This study provides the first large-scale measurement of WM volume reduction in children with AS.

Department of Emergency, First Affiliated Hospital of Gannan Medical University, 128 Jinling Road, Zhanggong District, Ganzhou City, Jiangxi Province, China.

Background: Several therapeutic drugs have been authorized for the treatment of patients with Coronavirus disease 2019 (COVID-19). However, further research on the mechanisms of action, efficacy, and target populations of these novel therapeutic drugs are necessary. This study included mild, moderate, severe, and critical COVID-19 patients to evaluate azvudine's effectiveness across different severity levels.
