BMSCs-Derived Extracellular VesiclemiR-29a-3p Improved the Stability of Rat Myasthenia Gravis by Regulating Treg/Th17 Cells.

Introduction: Myasthenia gravis (MG) is an autoimmune disorder. Microvesicle-derived miRNAs have been implicated in autoimmune diseases. However, the role of microvesicle-derived miR-29a-3p in MG remains poorly understood.

Numerical investigation of the rider's head injury in typical single-electric self-balancing scooter accident scenarios.

As the use of electric self-balancing scooters (ESSs) increases, so does the number of related traffic accidents. Because of the special control method, mechanical structure and driving posture, ESSs are prone to various single-vehicle accidents, such as collisions with fixed obstacles and falls due to mechanical failures. In various ESS accident scenarios, the rider's head injury is the most frequent injury type.

A multidisciplinary clinic approach to improve physician-related diagnostic delay for patients with axial spondyloarthritis: a retrospective study.

Objective: To assess the diagnostic delay (DD) and physician-related DD (pDD) in patients with axial spondyloarthritis (SpA) and the potential benefits of a multidisciplinary clinic (MDC) approach.

Methods: A retrospective study was undertaken among patients with axial SpA, which aimed to analyse DD, pDD and their risk factors. The influence of pDD on disease outcomes was examined.

The performance of different anti-dsDNA autoantibodies assays in Chinese systemic lupus erythematosus patients.

To compare the performance of different commercial anti-dsDNA autoantibody assays, including multiplex-based immunoassay (Bio-Plex), Farr radioimmunoassay (Farr), ELISA, chemiluminescent immunoassay (CLIA), and Crithidia Luciliae indirect immunofluorescence test (CLIFT) in Chinese patients with systemic lupus erythematosus (SLE). SLE patients (n = 119) as well as healthy controls (n = 200) and disease controls (n = 100) were recruited, and serum anti-dsDNA autoantibodies were detected by Bio-Plex, Farr, two ELISA assays (Medical & Biological Laboratories-ELISA, EUROIMMU-ELISA), CLIA, and a standard CLIFT. The correlation of anti-dsDNA autoantibody levels to SLE disease activity was calculated, and the specificity and sensitivity of these methods were measured by receiver-operator characteristic (ROC) curve analysis.

Immobilization of glucoamylase onto novel porous polymer supports of vinylene carbonate and 2-hydroxyethyl methacrylate.

Glucoamylase was immobilized onto novel porous polymer supports. The properties of immobilized glucoamylase and the relationship between the activity of immobilized enzyme and the properties of porous polymer supports were investigated. Compared with the native enzyme, the temperature profile of immobilized glucoamylase was widened, and the optimum pH was also changed.
