Effect of UV-B radiation on the photoprotective and antioxidant response in Vaccinium corymbosum L.: An approach to the UV-B resistance mechanisms.
(2017)
Despite the Montreal protocol success and the eventual recovery of the ozone layer over Antarctica, there are still concerns about increased levels of ultraviolet-B (UV-B) radiation in the Southern Hemisphere. It is expected ...
2-acetylphenothiazine protects L929 fibroblasts against UVB-induced oxidative damage
(2021-03-01)
Ultraviolet B (UVB) light corresponds to 5% of ultraviolet radiation. It is more genotoxic and mutagenic than UVA and causes direct and indirect cellular damage through the generation of reactive oxygen species (ROS). Even ...
Photoprotective effect of Pothomorphe umbellata on UVB radiation-induced biomarkers involved in carcinogenesis of hairless mouse epidermis
(TAYLOR & FRANCIS INC, 2009)
In this study we assessed the protective effect of topical application of Pothomorphe umbellata extract on ultraviolet B (UVB)-induced skin lesion parameters in hairless mouse epidermis. A single dose of UVB irradiation ...
Antiaging activity, molecular docking, and prediction of percutaneous absorption parameters of quinoline?hydrazone hybrids
(Medicinal Chemistry Research, 2020)
A role for β,β-xanthophylls in Arabidopsis UV-B photoprotection
(Oxford University Press, 2018-09)
Plastidial isoprenoids, such as carotenoids and tocopherols, are important anti-oxidant metabolites synthesized in plastids from precursors generated by the methylerythritol 4-phosphate (MEP) pathway. In this study, we ...
UV-B impairs growth and gas exchange in grapevines grown in high altitude
(Wiley Blackwell Publishing, Inc, 2013-09)
We previously demonstrated that solar ultraviolet-B (UV-B) radiation levels in high altitude vineyards improve berry quality in Vitis vinifera cv. Malbec, but also reduce berry size and yield, possibly as a consequence of ...
Evaluation of Protective Effect of a Water-In-Oil Microemulsion Incorporating Quercetin Against UVB-Induced Damage in Hairless Mice Skin
(CANADIAN SOC PHARMACEUTICAL SCIENCES, 2010)
Purpose. Histological aspects were considered in order to evaluate the in vivo photoprotective effect of a w/o microemulsion containing quercetin against UVB irradiation-induced dermal damages. The toxicity in cell culture ...
Fungal Endophytes Enhance the Photoprotective Mechanisms and Photochemical Efficiency in the Antarctic Colobanthus quitensis (Kunth) Bartl. Exposed to UV-B Radiation
(FRONTIERS MEDIA SA, 2020)
Antarctic plants have developed mechanisms to deal with one or more adverse factors which allow them to successfully survive such extreme environment. Certain effective mechanisms to face adverse stress factors can arise ...
Exposure to UV-B Radiation Leads to Increased Deposition of Cell Wall-Associated Xerocomic Acid in Cultures of Serpula himantioides
(2019)
Many fungi are thought to have developed morphological and physiological adaptations to cope with exposure to UV-B radiation, but in most species, such responses and their protective effects have not been explored. Here, ...
