Endoplasmic Reticulum Stress Is Involved in Muscular Pathogenesis in Idiopathic Inflammatory Myopathies.

Endoplasmic reticulum (ER) stress plays pivotal roles in the regulation of skeletal muscle damage and dysfunction in multiple disease conditions. We postulate the activation of ER stress in idiopathic inflammatory myopathies (IIM). Thirty-seven patients with immune-mediated necrotizing myopathy (IMNM), 21 patients with dermatomyositis (DM), 6 patients with anti-synthetase syndrome (ASS), and 10 controls were enrolled.

Contribution of relapse-associated worsening to overall disability accrual in patients with relapsing-onset multiple sclerosis: A mediation analysis.

Objective: The neurological disability accumulation in patients with relapsing-onset multiple sclerosis (MS) is commonly attributed to relapse-associated worsening (RAW) and progression independent of relapse activity (PIRA). Using a mediation model, this research aimed to investigate and quantify the contributions of RAW and PIRA to the overall disability accrual.

Methods: Clinical data, containing Expanded Disability Status Scale (EDSS) scores, duration, attack number, and demographics, were collected from 121 patients with relapsing-onset MS in China and included in the mediation model.

Distinct Immunological Features of Inflammatory Demyelinating Diseases of the Central Nervous System.

Objective: The immunological features between neuromyelitis optica spectrum disorder (NMOSD), multiple sclerosis (MS), and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), lacked systemic comparisons. Accordingly, we aimed to investigate immunological differences between NMOSD, MS, and MOGAD.

Methods: Patients with MOGAD, MS, and NMOSD who received immunological tests including cytokine profiles and cytometry analysis of the lymphocyte subgroups were retrospectively reviewed and divided into training and validation sets.

Characteristics of immune and inflammatory responses among different age groups of pediatric patients with COVID-19 in China.

Background: Severe cases of coronavirus disease 2019 (COVID-19) among pediatric patients are more common in children less than 1 year of age. Our aim is to address the underlying role of immunity and inflammation conditions among different age groups of pediatric patients.

Methods: We recruited pediatric patients confirmed of moderate COVID-19 symptoms, admitted to Wuhan Children's Hospital from January 28th to April 1st in 2020.

Clinical characteristics of sleep disorders in patients with Parkinson's disease.

In order to investigate the sleep quality and influencing factors in patients with Parkinson's disease (PD), 201 PD patients were enrolled and underwent extensive clinical evaluations. Subjective sleep evaluation was assessed using the Pittsburgh Sleep Quality Index (PSQI), and the Epworth Sleepiness Scale (ESS). It was found that poor sleep quality (77.

αν and β1 Integrins mediate Aβ-induced neurotoxicity in hippocampal neurons via the FAK signaling pathway.

αν and β1 integrins mediate Aβ-induced neurotoxicity in primary hippocampal neurons. We treated hippocampal neurons with 2.5 µg/mL 17E6 and 5 µg/mL ab58524, which are specific αν and β1 integrin antagonists, respectively, for 42 h prior to 10 µM Aβ treatment.
