The human skin is an integral system that acts as a physical and immunological barrier to
outside pathogens, toxicants, and harmful irradiations. Environmental ultraviolet rays (UV) …

Oxygen is the most essential molecule for life; since it is a strong oxidizing agent, it can
aggravate the damage within the cell by a series of oxidative events including the …

Nicotinamide (vitamin B3) protects from ultraviolet (UV) radiation-induced carcinogenesis in
mice and from UV-induced immunosuppression in mice and humans. Recent double …

The ecotoxicology of nano-TiO 2 has been extensively studied in recent years; however, few
toxicological investigations have considered the photocatalytic properties of the substance …

Mitochondrial DNA damage has been used as a successful and unique biomarker of tissue
stress. A valuable example of this is sun damage in human skin which leads to ageing and …

In this work a pigment material, cerium phosphate (CePO4) was investigated as a new UV
filter with excellent morphological characteristics, desirable UV absorption features, low …

Purpose.: Epidemiologic studies have linked UV-B exposure to development of cortical
cataracts, but the underlying molecular mechanism (s) is unresolved. Here, we used a …

Optical radiation extends between microwaves and X-rays of the electromagnetic radiation
and includes ultraviolet (UV), visible light (VL) and infrared (IR) components. The dose of …

The effects of ultraviolet (UV) radiation on the surface morphology and the surface chemistry
of an epoxy-resin-based coating were characterized with both scanning electron microscopy …

TiO2 photocatalysis can be used to kill surface adherent bacteria on biomaterials, and is
particularly interesting for use with percutaneous implants and devices. Its efficiency and …
