Ultraviolet Radiation Damage in DNA
Introduction The evolution of most forms of life has occurred in an environment exposed to the ultraviolet (UV) and visible radiation emanating from the sun. When molecules in living cells absorb photons in this region of the electromagnetic spectrum they are promoted to excited electronic states and this process can have profound biological consequences. In general, visible wavelengths (400-78...
متن کاملMeasuring vacuum ultraviolet radiation-induced damage
During plasma processing of semiconductors, ultraviolet ~UV! and vacuum ultraviolet ~VUV! radiation are present, but their effects can be difficult to separate from those due to charged particles incident on the wafer. The contribution of VUV photon irradiation to gate-oxide damage, and damage to dielectric materials in general, was examined using two measurement techniques that can predict the...

متن کاملChemoprevention of ultraviolet radiation-induced skin cancer.
The use of chemical and physical sunscreening agents has increased dramatically during the last two to three decades as an effective means of preventing sunbum. The use of high sunprotection factor sunscreens has also been widely promoted for the prevention of skin cancer, including melanoma. Whereas sunscreens are undoubtedly effective in preventing sunbum, their efficacy in preventing skin ca...
متن کاملUltraviolet Radiation-induced DNA Damage and Its Photorepair in the Skin of the Platyfish Xiphophorus1
Fluence response relationships for the induction of DNA damage in the skin of I \ -irradiali-«!Xiphophorus fish were obtained by quantitative gel electrophoresis of unlabeled DNA following extraction and treatment with an enzyme preparation that makes single strand breaks next to cyclobutane pyrimidine dimers. A buffer containing 7 M urea minimized the degradation of DNA during extraction and ...
