[Melanoma, altitude, and UV-B radiation].
BACKGROUND AND OBJECTIVES UV radiation is the main modifiable risk factor for the development of cutaneous melanoma. Many people in the Spanish province of Granada live at high altitudes and, therefore, receive high doses of UV-B radiation. The aims of this study were to assess the possible association between melanoma and altitude and to measure the daily erythemal dose at different altitudes....
متن کاملP1 Epigenetic Regulation in Leaves of High Altitude Maize Landraces: Effect of UV-B Radiation
P1 is a R2R3-MYB transcription factor that regulates the accumulation of a specific group of flavonoids in maize floral tissues, such as flavones and phlobaphenes. P1 is also highly expressed in leaves of maize landraces adapted to high altitudes and higher levels of UV-B radiation. In this work, we analyzed the epigenetic regulation of the P1 gene by UV-B in leaves of different maize landraces...
متن کاملUV radiation, latitude, and melanoma in US Hispanics and blacks.
BACKGROUND Little information exists on the epidemiology of melanoma and the role of solar radiation in the development of melanoma in pigmented populations. OBJECTIVE To evaluate the relationship between exposure to solar radiation and the incidence of melanoma in US Hispanics and blacks. DESIGN Population-based ecological study. SETTING State cancer registries of New York, New Jersey, I...
متن کاملPolychlorinated biphenyls (PCB), UV radiation, and cutaneous malignant melanoma
Several older epidemiologic studies have suggested that exposure to polychlorinated biphenyls (PCBs) may increase risk of cutaneous malignant melanoma (CMM). These investigations, however, have not been able to control for sun exposure, and sun sensitivity, which are major risk factors for this cancer. We conducted a pilot study to examine the possible association between plasma levels of PCBs ...
متن کاملEffect of UV-B radiation on photosynthetic pigments and UV-absorbing compounds of three different soybean cultivars (Glycine max L.).
The effects of UV-B radiation on the amount of chlorophyll a, b, carotenoids, flavonoids, anthocyanins, and polyphenols of three soybean cultivars was studied. After germination in the incubator, plants were put in pots of soil and during 3 weeks and irrigated with Hoagland solution every day. After 3 weeks, plants were exposed to UV-B for 20 min every day for a week. In each cultivar, UV-B red...
