The global probiotics market has been continuously growing, driven by consumer demand for immune-enhancing functional foods, dietary supplements, and natural therapeutics for gastrointestinal and gut function-mediated diseases. Probiotic microorganisms represent a diverse group of strains with complex but generalized mechanistic patterns. This review describes the various immunomodulatory mechanisms by which probiotics exert their effects, including the competitive exclusion of pathogenic microbes, production of antimicrobial substances, modulation of the immune system, and improvement of gut barrier function.

Recent evidence indicates that PZA acts through disruption of coenzyme A synthesis under conditions that promote cellular stress. In contrast to its bactericidal action , PZA shows weak bacteriostatic activity against in axenic culture.

Background: The ionic mechanism underlying Brugada syndrome (BrS) arises from an imbalance in transient outward current flow between the epicardium and endocardium. Previous studies report that artemisinin, originally derived from a Chinese herb for antimalarial use, inhibits the Ito current in canines. In a prior study, we showed the antiarrhythmic effects of artemisinin in BrS wedge preparation models.

Rapamycin, a macrocyclic antibiotic derived from the actinomycetes Streptomyces hygroscopicus, is a widely used immunosuppressant and anticancer drug. Even though rapamycin is regarded as a multipotent drug acting against a broad array of anomalies and diseases, the mechanism of action of rapamycin and associated pathways have not been studied and reported clearly. Also reports on the binding of rapamycin to cancer cell receptors are limited to the serine/threonine protein kinase mTORC1.

This study presents the fabrication and characterization of mixed matrix membranes (MMMs) incorporating green-synthesized silver nanoparticles (AgNPs) using Hibiscus Rosa sinensis extract within a polyethersulfone (PES) matrix for nanofiltration (NF) application. The membranes were evaluated for their pure water permeability, salt rejection, dye removal, and antifouling performance. Results showed that the membrane with 0.
