Plants use sunlight for photosynthesis and, as a consequence, are exposed to the ultraviolet (UV) radiation that is present in sunlight. UV radiation is generally divided into three classes: UV-C, UV-6, and UV-A. The UV-C region of the UV spectrum includes wavelengths below 280 nm; these highly energetic wavelengths are effectively absorbed by ozone in the stratosphere and, thus, are not presen...

abstract during these protracted years, mankind’s main foods consist of grains-specially wheat, oats and rice. granary production and its storage have been one of the main concerns of a human being for a long time. microwave radiation as a safe insect control agent could secure high mortality rate of insect population by increasing the temperature of insects’ body and its niche. low temperature...

UV-C radiation is known to induce metabolic modifications in plants, particularly to secondary metabolite biosynthesis. To assess these modifications from a global and untargeted perspective, the effects of the UV-C radiation of the leaves of three different model plant species, Cissus antarctica Vent. (Vitaceae), Vitis vinifera L. (Vitaceae) and Cannabis sativa L. (Cannabaceae), were evaluated...

In an attempt to develop better combination therapies for use with local radiation, the interaction between bleomycin and hyperthermia +/- radiation was studied in the FSaIIC tumor system. In cells exposed in vitro to bleomycin at 37 degrees C and at pH 7.40, the drug was substantially more toxic toward normally oxygenated than hypoxic cells. At hyperthermic temperatures (42 degrees or 43 degre...
