Cell culture media (RPMI 1640, Dulbecco's Minimal Essential Medium and yeast extract-
peptone-glucose medium) were found to oxidize dichlorodihydrofluorescein diacetate and …

This chapter summarizes recent research on the biology of reactive oxygen species (ROS).
The chapter is focused on the bimodal actions of ROS, which can be summarized as both …

Reactive oxygen species (ROS) have emerged as important signaling molecules in the
regulation of various cellular processes. In our study, we investigated the effect of a wide …

Oxidative stress (OS) has been implicated in various degenerative diseases in aging. In an
attempt to quantify OS in a cell model, we examined OS induced by incubating for 30 min …

Singlet oxygen is generated by several cellular, enzymatic, and chemical reactions as well
as by exposure to UV or visible light in the presence of a sensitizer. Consequently, this …

Biological effects of ultraviolet A (UVA) irradiation have been ascribed to the photochemical
generation of singlet oxygen. Not all effects described in the literature, however, are …

Induction of oxidative stress by drugs and other xenobiotics is an important mechanism of
cytotoxicity. However, in vitro studies on the relationship between oxidative stress and …

Reactive oxygen species (ROS) are natural products inevitably generated along cellular
metabolism. Due to their highly reactive nature, which can damage DNA, proteins and lipids …

There are many pieces of evidence suggesting the mediating role of reactive oxygen
species (ROS) in cell life, stress and death, and it is known that ROS at different …

As ultraviolet (UV) radiation is naturally and ubiquitously emitted by the sun, almost
everyone is exposed to it on a daily basis, and it is necessary for normal physiological …
