Background: Gestational diabetes mellitus (GDM) is a metabolic disorder that arises during pregnancy and heightens the risk of placental dysplasia. Ginsenoside Re (Re) may stabilize insulin glucagon to regulate glucose levels, which improve diabetes-associated diseases. Purpose: This study aims investigate mechanism in high (HG)-induced apoptosis trophoblasts through endoplasmic reticulum stress (ERS)-related protein CHOP/GADD153. Research Design: Human trophoblast cells HTR-8/SVneo were...

Dermatomyositis and polymyositis (DM/PM) are systemic autoimmune diseases characterized by proximal muscle weakness. The underlying pathogenetic mechanism of this disease remains under-researched. Here, using proteomics analysis, a great overlap differentially expressed plasma exosomal proteins involved in the complement coagulation cascade pathway, including FGA, FGB, FGG, C1QB, C1QC, VWF, was identified DM/PM patients versus healthy controls. Correlation analysis showed that expression...

Accumulating evidence indicates that antibodies can protect against some intracellular pathogens. Mycobacterium bovis is an bacterium, and its cell wall (CW) essential for virulence survival. However, the questions of whether play a protective role in immunity M. infection what effects specific to CW have still remain unclear. Here, we report targeting isolated pathogenic strain attenuated bacillus Calmette-Guérin (BCG) could induce protection virulent

Respiratory mucosal immunization is an effective strategy against tuberculosis (TB), and vaccines require adjuvants that can promote protective immunity without deleterious inflammation. Mucosal BCG (Bacille Calmette-Guerin) effective, but it causes a severe inflammatory response in the lung. A novel less cytotoxic vaccine AH-PB containing Mycobacterium (Mtb) cell surface antigens Ag85A HspX (AH), as well polyinosinic-polycytidylic acid (Poly IC) bovine neutrophil β-defensin-5 (B5) were...

Background Autoimmune thyroid disease (AITD), which is characterized by an increased presence of autoantibodies (TAbs), such as antibodies against peroxidase (TPOAbs) and thyroglobulin (TgAbs), has been reported to be associated with rheumatoid arthritis (RA) because AITD RA both involve autoimmunity. However, few data are available on the incidence TAbs in Chinese patients, studies association between joint damage well synovitis patients remain sparse. Here, we aimed evaluate a consecutive...

Laser tweezers Raman spectroscopy enables multiplexed, quantitative chemical and morphological analysis of individual bionanoparticles such as drug-loaded nanoliposomes, yet it requires minutes-scale acquisition times per particle, leading to a lack statistical power in typical small-sized data sets. The long present bottleneck not only measurement time but also the analytical throughput, particle concentration (and thus throughput) must be kept low enough avoid swarm measurement. effective...
