Oxidative stress in skin plays a major role in the aging process. This is true for intrinsic aging
and even more for extrinsic aging. Although the results are quite different in dermis and …

Reactive oxygen species (ROS) are generated as by-products of normal cellular metabolic
activities. Superoxide dismutase, glutathione peroxidase, and catalase are the enzymes …

Nanotechnology has had a significant impact on medicine in recent years, its application
being referred to as nanomedicine. Nanoparticles have certain properties with biomedical …

Thioredoxin, thioredoxin reductase and NADPH, the thioredoxin system, is ubiquitous from

Abstract Background Hydrogen peroxide (H 2 O 2)-induced mitochondrial oxidative damage
is critical to intestinal ischemia/reperfusion (I/R) injury, and PRDX3 is an efficient H 2 O 2 …

This review focuses on the role of oxidative processes in atherosclerosis and its resultant
cardiovascular events. There is now a consensus that atherosclerosis represents a state of …

▪ Abstract The production of reactive oxygen species (ROS), such as O2− and H2O2, is an
unavoidable consequence of aerobic metabolism. In plant cells the mitochondrial electron …

Defective sperm function has been identified as the most common cause of infertility. The
objective of this study was to review recent findings on the effects of various antioxidants on …

Free radicals and other so-called 'reactive species' are constantly produced in the brain in
vivo. Some arise by 'accidents of chemistry', an example of which may be the leakage of …
