[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 کاملRoom decontamination with UV radiation.
OBJECTIVE To determine the effectiveness of a UV-C-emitting device to eliminate clinically important nosocomial pathogens in a contaminated hospital room. METHODS This study was carried out in a standard but empty hospital room (phase 1) and in a room previously occupied by a patient with methicillin-resistant Staphylococcus aureus (MRSA) or vancomycin-resistant Enterococcus (VRE) infection (...
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...
متن کاملUV-B radiation effects on terrestrial plants – A perspective
Both terrestrial and aquatic plants, the primary producers supporting life on earth, can be threatened by global climate change and particularly by UV-B radiation due to the depletion of the ozone layer in both Poles. The injurious effects of UV-B have been assessed mainly through in vitro studies and vary greatly according the dose received, the exposition period and the sensitivity of the spe...
متن کاملMolecular responses of plant cells to UV-B radiation
UV-B radiation (UV-B: 280-320 nm) can cause a wide range of responses in plant cells. These responses depend on the perception of the UV-B radiation, signal transduction mechanisms and modification of gene expression. Studies over the last ten years have revealed a complex molecular response of plant cells to UV-B radiation. Specific changes in gene activity take place and a number of signal tr...
