WebBackground Skin photoaging is the damage caused by excessive exposure to ultraviolet (UV) irradiation. We investigated the effect of adenosine triphosphate (ATP) supplementation on UVB-induced photo... WebPhotoadaptation is a protective mechanism that the skin damage of the response to exposure to UV reduces after repeated exposures, which was verified in phototherapy for psoriasis. 38 The melatonin, a hormone connected with light (seasonality and circadian rhythm), was found to have utility of maintaining skin homeostasis by suppressing of UV ...

WebThus, the SS phytoplankton is capable of fast photoadaptation. In earlier studies, it was shown that in the Arctic Ocean, the assimilation number (P b) linearly and positively depended on PAR [47,53,91,92]. The absence of a “plateau” on the curves of the relationships between P b and PAR implies that arctic phytoplankton is light-limited.
WebAug 23, 2010 · Photoadaptation defects were determined by measuring light induction of al-3 (F) and sub-1 (G) at LL60 using RT quantitative PCR analysis (n = 3, mean values ± SE). Asterisks indicate statistical significance when compared with the Δ vvd strain at LL60 as determined by an unpaired t test.
