Front Cover: Ultraviolet radiation oxidative stress affects eye health (J. Biophotonics 7/2018)

Ultraviolet radiation and the eye.

Moderate exposure to ultraviolet radiation (UVR) from the sun is a necessary part of maintaining normal health. Ultraviolet radiation is critical for formation of VitaminD and the normal healthy growth of bones and teeth. However, excessive exposure to UVR has no health benefits and can lead to adverse consequences for the skin and eye. When the body receives excessive UVR exposure on a chronic...

Acute exposure to solar simulated ultraviolet radiation affects oxidative stress-related biomarkers in skin, liver and blood of hairless mice.

The ultraviolet (UV) region of solar radiation is a critical factor in the initiation and development of a number of skin diseases. However, it is not only skin which is directly exposed to solar light that is affected by UV radiation, through low molecular weight mediators, generated upon irradiation, "non-skin" tissues can also be affected. The aim of this study was to examine in detail, the ...

Fucodiphlorethol G Purified from Ecklonia cava Suppresses Ultraviolet B Radiation-Induced Oxidative Stress and Cellular Damage

Fucodiphlorethol G (6'-[2,4-dihydroxy-6-(2,4,6-trihydroxyphenoxy)phenoxy]biphenyl-2,2',4,4',6-pentol) is a compound purified from Ecklonia cava, a brown alga that is widely distributed offshore of Jeju Island. This study investigated the protective effects of fucodiphlorethol G against oxidative damage-mediated apoptosis induced by ultraviolet B (UVB) irradiation. Fucodiphlorethol G attenuated ...
