Carotenoids constitute a ubiquitous group of isoprenoid pigments. They are very efficient
physical quenchers of singlet oxygen and scavengers of other reactive oxygen species …

The present manuscript is a conceptual review concerning the photo-Fenton reaction at near-
neutral pH, used for bacterial inactivation. In this first Part, an overview of the mechanisms …

Photo-induced damage to proteins occurs via multiple pathways. Direct damage induced by
UVB (λ 280–320 nm) and UVA radiation (λ 320–400 nm) is limited to a small number of …

There has been considerable public and scientific interest in the use of phytochemicals
derived from dietary components to combat human diseases. They are naturally occurring …

Photolyase is an enzyme that uses light to catalyze DNA repair. To capture the reaction
intermediates involved in the enzyme's catalytic cycle, we conducted a time-resolved …

New methods to protect skin from photodamage from sun exposure are necessary if we are
to conquer skin cancer and photoaging. Sunscreens are useful, but their protection is not …

Background Excessive generation of radical oxygen species (ROS) is a contributor to skin
pathologies. Resveratrol (RSV) is a potent antioxidant. Solid lipid nanoparticles (SLN) and …

Melanoma and nonmelanoma skin cancers are among the most prevalent cancers in the
human population. Solar ultraviolet radiation is considered a major etiological factor but the …

Solar radiation is the primary source of human exposure to ultraviolet (UV) radiation.
Overexposure without suitable protection (ie, sunscreen and clothing) has been implicated …

ABSTRACT DNA damage induced by UV radiation is a critical event in skin
photocarcinogenesis. However, the role of racial/ethnic origin in determining individual UV …
