Abstract excerpt
The direct tumorigenic effects of ultraviolet radiation (UVR) are well known. Specifically, the premutagenic lesions of UVB (290-320 nm), are known to be the most important molecular events in UVR tumorigenicity. The less carcinogenic UVA (320-400 nm) mainly generates oxidative damage in the DNA via photodynamic generation of active oxygen species involving endogenous or exogenous photosensitizers. Several...
