ABSTRACT Background Myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) can radiographically mimic multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). The disease hallmarks cortical lesion, central vein sign (CVS) and paramagnetic rim lesions identified in MS have not yet been comprehensively investigated in ...

SARS‐CoV‐2 Is Linked to Brain Volume Loss in Multiple Sclerosis
ABSTRACT Objective The impact of SARS‐CoV‐2 infection on brain and spinal cord pathology in patients with multiple sclerosis (pwMS) remains unclear. We aimed to describe changes in brain lesion activity and brain and spinal cord volumes following SARS‐CoV‐2 infection.

Bernoulli numbers and certain convolution sums with divisor functions
In this paper, we investigate the convolution sums ∑(a+b+c)x=na,∑ax+by=nab,∑ax+by+cz=nabc,∑ax+by+cz+du=nabcd, where a,b,c,d,x,y,z,u,n∈N. Many new equalities and inequalities involving convolution sums, Bernoulli numbers and divisor functions have also ...

Detecting rs‐fMRI Networks in Disorders of Consciousness: Improving Clinical Interpretability
ABSTRACT Background Preserved resting‐state functional MRI (rs‐fMRI) networks are typically observed in Disorders of Consciousness (DOC). Despite the widespread use of rs‐fMRI in DOC, a systematic assessment of networks is needed to improve the interpretability of data in clinical practice.

ABSTRACT Objective The cervical spinal cord (cSC) is highly relevant to clinical dysfunction in multiple sclerosis (MS) but remains understudied using quantitative magnetic resonance imaging (MRI). We assessed magnetization transfer ratio (MTR), a semi‐quantitative MRI measure sensitive to MS‐related tissue microstructural changes, in the cSC and its ...

Correlation Between Irisin and Cognitive Functions in Alzheimer Dementia
ABSTRACT Objective The myokine irisin, a recent positive mediator of exercise in the brain, shows neuroprotective functions against Alzheimer's disease (AD). The association between irisin and cognition has never been explored in a biologically defined cohort of patients.

Understanding Mechanisms of Whole Brain and Regional Grey Matter Atrophy in Children With MOGAD
ABSTRACT Objective To investigate the mechanisms driving whole brain and regional grey matter (GM) volume changes along with their clinical correlates in paediatric myelin oligodendrocyte glycoprotein antibody (MOG‐Ab)–associated disease (MOGAD). Methods One‐hundred‐nine paediatric MOGAD patients from two UK centres underwent MRI at attack nadir and ...

As many patients with inflammatory arthritis (IA) have chronic pain, understanding how to best assess and manage pain in IA is a priority. Comorbid depression is prevalent in adults with IA, affecting 15% to 39% of people. Although pain and depression are thought to be associated in IA, this concept is largely based on cross‐sectional data.

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.
