Dietary Supplementation of Antioxidant Compounds Prevents Light-Induced Retinal Damage in a Rat Model

Biomedicines, 2021
Light-induced retinal damage (LD) is characterized by the accumulation of reactive oxygen species leading to oxidative stress and photoreceptor cell death. The use of natural antioxidants has emerged as promising approach for the prevention of LD.

DNA Oxidation Photoinduced by Norharmane Rhenium(I) Polypyridyl Complexes: Effect of the Bidentate N,N′-Ligands on the Damage Profile [PDF]

, 2018
ReI-polypyridyl complexes have interesting and distinctive photochemical and photosensitizing properties. This work describes the capability to induce (or photoinduce) DNA damage of three ReI-complexes with a naturally occurring alkaloid called ...

Cell death mechanisms in retinal phototoxicity

Journal of Photochemistry and Photobiology, 2023
Retinal phototoxicity is the main mechanism by which light induces damage to the retina, the sensitive part of the eye. The impact of light on the different retinal layers varies depending on several factors including the wavelength of the incident light,

Alpha-ketoglutarate protects Streptomyces coelicolor from visible light-induced phototoxicity

Biochemistry and Biophysics Reports, 2017
It has been known that some Streptomyces species, including the model strain Streptomyces coelicolor, are vulnerable to visible light. Much evidence demonstrated that the phototoxicity induced by visible light is a consequence of the formation of ...
