Viral infections of the central nervous system increase the risk of knee osteoarthritis: a two-sample mendelian randomization study.

Objective: Osteoarthritis (OA) represents a condition under the influence of central nervous system (CNS) regulatory mechanisms. This investigation aims to examine the causal association between viral infections of the central nervous system (VICNS) and inflammatory diseases of the central nervous system (IDCNS) and knee osteoarthritis (KOA) at the genetic level.

Methods: In this investigation, VICNS and IDCNS were considered as primary exposure variables, while KOA served as the primary outcome.

Adenosine diphosphate stimulates VEGF-independent choroidal endothelial cell proliferation: A potential escape from anti-VEGF therapy.

We hypothesized that a strategy employing tissue-specific endothelial cells (EC) might facilitate the identification of tissue- or organ-specific vascular functions of ubiquitous metabolites. An unbiased approach was employed to identify water-soluble small molecules with mitogenic activity on choroidal EC. We identified adenosine diphosphate (ADP) as a candidate, following biochemical purification from mouse EL4 lymphoma extracts.

Analysis of related factors for systemic lupus erythematosus flare after SARS-Cov-2 infection: A retrospective cohort study.

Objective: Since COVID-19 infections are more common in systemic lupus erythematosus (SLE) patients, most recent research has focused on the outcome of COVID-19, with fewer studies on disease activity in SLE. This research aims to evaluate flares in SLE with COVID-19 infection while investigating predictive factors.

Methods: A questionnaire survey was conducted to collect information on patients with previously diagnosed SLE from multi-center.

ZnT35C Maintains Zinc Homeostasis to Regulate Spermatogenesis in Drosophila Testis.

Zinc homeostasis contributes significantly to numerous physiological processes. Drosophila ZnT35C protein, a zinc transporter encoded by CG3994, is chiefly located on the cell membrane and facilitates the transport of zinc from the cytoplasm to the extracellular space to sustain zinc homeostasis within the organism. Previous studies about ZnT35C have involved diverse structures such as the Malpighian tubules, adult brain, and sensory nervous system.

Bibliometric mapping of mesenchymal stem cell therapy for bone regeneration from 2013 to 2023.

Mesenchymal stem cells (MSCs) have shown significant potential in bone regeneration and regenerative medicine in recent years. With the advancement of tissue engineering, MSCs have been increasingly applied in bone repair and regeneration, and their clinical application potential has grown through interdisciplinary approaches involving biomaterials and genetic engineering. However, there is a lack of systematic reviews summarizing their applications in bone regeneration.
