Exposure to ultraviolet (UV) radiation from the sun can elicit both positive and negative effects on the skin. Among the three types of UV radiation, UVB (280-315 nm) is particularly detrimental, causing sunburns, skin cancer, and premature aging. Furthermore, UV exposure induces the generation of reactive oxygen species (ROS), which the skin recognizes as external ROS. This study investigates …
The gut microbiota determines the intestinal health status of the host by regulating gut epithelial and immune functions. Depletion of the beneficial gut microbiota after radiation exposure contributes to an exaggerated inflammatory response and dysregulation of intestinal epithelial cells. Previous studies demonstrated that administration of beneficial gut microbiota, Lactobacillus acidophilus…
