Animal models of ultraviolet radiation (UVR)-induced cutaneous melanoma.
The incidence of cutaneous melanoma continues to increase in many parts of the world including the United States. The American Cancer Society predicts that there will be approximately 53,600 new cases of melanoma in the United States during 2002 and that there will be 7,400 deaths from melanoma during the same time period. Increased understanding of the underlying mechanisms and risk factors in...
متن کاملIncreased tolerance to ultraviolet radiation (UVR) and cotolerance to cadmium in UVR-acclimatized freshwater periphyton
We studied the long-term acclimatization of freshwater periphyton communities exposed to low and high ultraviolet radiation (UVR) intensities that simulate UVR doses received by lowland and high-mountain streams of central Europe. To assess changes induced by UVR, we compared the community structure (species and biomass), function (photosynthetic yield), and tolerance to UVR and cadmium of peri...
متن کاملThe Role of Photolabile Dermal Nitric Oxide Derivates in Ultraviolet Radiation (UVR)-Induced Cell Death
Human skin is exposed to solar ultraviolet radiation comprising UVB (280-315 nm) and UVA (315-400 nm) on a daily basis. Within the last two decades, the molecular and cellular response to UVA/UVB and the possible effects on human health have been investigated extensively. It is generally accepted that the mutagenic and carcinogenic properties of UVB is due to the direct interaction with DNA. On...
متن کاملPrevalence of exposure to solar ultraviolet radiation (UVR) on the job in Canada.
OBJECTIVE Over one third of all newly diagnosed cancers in Canada in 2010 were skin cancer, despite the fact that skin cancer is largely preventable by limiting ultraviolet radiation (UVR) exposure. Outdoor workers are at risk of exposure to UVR, yet the prevalence of exposure in Canada is unknown. The objective of this study was to estimate the number of outdoor workers in Canada. METHODS Bu...
متن کاملUltraviolet radiation-induced cataract: age and maximum acceptable dose.
PURPOSE To investigate the effect of age on ultraviolet radiation-B (UVR-B)-induced cataract and to detect the maximum acceptable dose in rats of different age groups. METHODS Four age groups of 20 rats each, aged 3, 6, 10, and 18 weeks, were included. Each age group was divided into five UVR-B dose subgroups. The rats were unilaterally exposed to UVR-B (lambda(max) = 302.6 nm, lambda(0.5) = ...
