Sunscreens play a critical role in protecting the skin from harmful ultraviolet (UV) radiation, including both UVA and UVB rays. Traditional inorganic UV filters, such as chemically synthesized zinc oxide (ZnO) and titanium dioxide (TiO₂), have limitations regarding biocompatibility, cost, and sustainability. This study investigates the effectiveness of green-synthesized ZnO nanoparticles (NPs) as an alternative, …

This paper explores the mechanisms and risk factors of cataract formation in two high-risk groups: radiotherapy patients and astronauts. Despite differences in radiation exposure, both groups experience cataractogenesis through similar mechanisms, such as DNA damage and oxidative stress. Unique risk factors, such as microgravity for astronauts, are compared with the high-dose exposure of radiotherapy patients. …
