Coumarins are of many different structures. They constitute an important class of
pharmacological agents possessing a range of different physiological activities including …

Reactive oxygen species (ROS) were viewed for a long time as unavoidable by-products of
normal cell catabolism. This view has recently changed and it is now apparent that ROS …

Coumarins are oxygen-containing molecules with specific benzopyrone nucleus. Different
coumarins are identified as antineurodegeneratives, anticoagulants, antioxidants …

Radiation chemists have been routinely using high-dose microsecond-pulsed irradiation for
almost 60 years, involving many thousands of studies, in the technique of “pulse radiolysis” …

Cells are exposed during their life span to fluctuating levels of reactive oxygen species
(ROS). To investigate the effects of a single ROS boost in vitro, human endothelial cells …

The antioxidant activities of exopolysaccharides (EPS) from endophytic bacterium
Paenibacillus polymyxa EJS-3 were evaluated by various methods in vitro and in vivo. In …

Oxidative stress caused by hydrogen peroxide (H 2 O 2) leads to cell death and has been
implicated in the pathogenesis of vitiligo. The nuclear factor E2-related factor 2 (Nrf2) …

Objective: The aim of this study was to investigate the antioxidative and neuroprotective
activities of various extracts from the fruit hull of mangosteen (Garcinia mangostana Linn …

Although reactive oxygen species (ROS) are well-established mediators of oxidative
damage and cell demise, the mechanisms by which they trigger specific cell death …

Differentiating apoptosis from necrosis is a challenge in single cells and in parenchymal
tissues. The techniques available, including in situ TUNEL (T erminal deoxyribonucleotide …
