Owing to the relatively high frequency of late thrombosis after stenting irradiated coronary arteries, the Food and Drug Administration required that the labeling of both gamma- and beta-radiation devices recently approved for clinical use explicitly advise avoidance of the placement of new stents. The...
Ionizing radiation enters the body and bores into wayward molecules that contain oxygen. In simple terms, those newly irradiated molecules then troll through the body causing all sorts of harm. Tardigrades, in their desiccated state, produce an abnormal amount of antioxidants ...
Inflammation normally results with the exposure of skin to UV radiation. White blood cells known as leukocytes stream into irradiated tissues. Oxidative damage occurs and produces free radicals, thereby depleting immune system cells. Numerous studies have found that topical application of green tea extra...
With a half-life of 30 years, it gives off penetrating radiation as it decays and can remain dangerous for hundreds of years. Once in the environment, it mimics potassium as it accumulates in the food chain; when it enters the human body, about 75 percent lodges in muscle tissue, includin...

one of the biggest radiation concerns for astronauts (and space-bound tardigrades) is a set of molecules called reactive oxygen species. Ionizing radiation enters the body and bores into wayward molecules that contain oxygen. In simple terms, those newly irradiated molecules then troll through the ...

food. Here, how, where, when and why aggressive interactions occur in Tephritidae flies is reviewed. A number of neglected issues deserving further research are highlighted, with a special focus on diel periodicity of aggression, cues evoking aggressive behavior, the role of previous experience on ...
