Exposure to nonextreme solar UV daylight: Spectral characterization, effects on skin and
photoprotection. Int J Mol Sci 16, 68-90.
Functional roles of flavonoids in
photoprotection: new evidence, lessons from the past.
Regular sun exposure, use of
photoprotection, and vitamin D supplementation were reported by 144 (64.0%), 44 (19.6%), and five (2.2%) of the women evaluated, respectively (Table 1).
Thus, the
photoprotection from naturally occurring substances has gained considerable attention in recent years due to their wide range of biological activities.
UV
photoprotection by combination topical antioxidants vitamin C and vitamin E.
Furthermore, flavonoids can protect plants from solar UV radiation through distinct mechanisms of
photoprotection, including UV absorption, direct and indirect antioxidant properties, and modulation of several signaling pathways [31].
Photoprotection by melanin- a comparison of black and Caucasion skin.
The natural
photoprotection of the nail bed is limited by the absence of melanocytes, stratum granulosum, and sebaceous glands.
A decrease in F v /F m could be the result of photochemical damage in the PSII reaction center, but could also be the result of
photoprotection, which is the dissipation of non-photochemical energy (Demmig and Bjorkman, 1987).
Studies showed that the efficacy of--carotene in systemic
photoprotection depends on the duration of treatment and on the dose.
2005) as far as we know little information related to photoinhibition and
photoprotection of ginkgo (Ginkgo biloba L.) is available yet.
