BACKGROUND Tanning lamp sessions have increased in Europe in recent years. Recent epidemiological studies have confirmed a proven link between melanoma and artificial UV exposure. However, in France, little information is available to determine the exposure of the population. This article presents the results from the 'Baromètre cancer 2010' concerning the proportion of users exposed to artific...

Ultraviolet radiation is known to inhibit photosynthesis, induce DNA destruction and cause damage to a wide variety of proteins and lipids. In particular, UV radiation between 200-300 nm becomes energetically very damaging to most of the terrestrial biological systems. On the other hand, UV radiation is usually considered one of the most important energy source on the primitive Earth for the sy...

The effects of enhanced UV-B radiation were investigated in the carnivorous plant Pinguicula vulgaris in a field experiment performed in Abisko, North Sweden (68° 21« N, 18° 49« E, 380 m above sea level). Potted plants were exposed to either ambient or ambient plus supplemental UV-B radiation, simulating a 15% ozone depletion. No effect was observed on either the epicuticular (external) or cell...

The combined and interactive effects of climatic and ecological factors are rarely considered in marine communities. We designed a factorial field experiment to analyze (1) the interactive effects of ambient UV radiation and consumers; and (2) the effects of photosynthetically active radiation (PAR 400 to 700 nm), UVA (320 to 400 nm) and UVB (280 to 320 nm) radiation on a marine hard-bottom com...

OBJECTIVES To establish the effect of sunless tanning products on tanning behaviors and to determine characteristics of sunless tanning product users. DESIGN A cross-sectional survey study conducted between May 30, 2007, and December 4, 2007. SETTING The Emory University campus and surrounding locations in Atlanta, Georgia. PARTICIPANTS Four hundred fifteen community and university-affili...

OBJECTIVE To assess the extent to which UV-A and UV-B radiation can penetrate the human fingernail plate. DESIGN The Dermalite UV light machine (National Biological, Beachwood, Ohio) was used as the source of UV radiation. The amount of UV-A and UV-B penetrating the nail plate was measured using a radiometer and compared with a control. SETTING Academic phototherapy clinic. PATIENTS Ten c...
