Abstract

Few studies have compared radiological features obtained on magnetic resonance imaging (MRI) between myelin oligodendrocyte glycoprotein antibody (MOG-ab)- and aquaporin 4 antibody (AQP4-ab)-positive patients. In this study, 77 MOG-ab and 92 AQP4-ab patients were enrolled. The results demonstrated that the brain MRI-based incidence of subcortical white matter lesions was higher in MOG-ab patients (p < .000) than in AQP4-ab patients and that the former therefore had a higher incidence of periventricular lesions (p = .003). The posterior limb of the internal capsule was more prone to lesions in MOG-ab patients (p = .019). Large lesions and U- or S-shaped lesions were also more frequent in MOG-ab (p < .000 and p = .013, respectively). Half of the MOG-ab patients had spinal cord involvement, and 36.5% presented with longitudinally extensive transverse myelitis (LETM). However, among the MOG-ab and AQP4-ab patients with spinal attack, there was no significant difference in the proportion with LETM (p = .057). In conclusion, a higher proportion of MOG-ab patients than AQP4-ab patients had brain lesions in white matter. Among MOG-ab patients who had an attack in the spinal cord, 65.5% also had LETM during the disease course. Conus med...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
