Oxidative stress plays an essential role in the pathogenesis of chronic diseases such as
cardiovascular diseases, diabetes, neurodegenerative diseases, and cancer. Long term …

Free radicals or reactive oxygen species (ROS) generated from various sources in the
environment as well as from cellular processes in the body are of serious health challenges …

Free radicals are constructed by natural physiological activities in the human cells as well as
in the environment. They may be produced as a result of diet, smoking, exercise …

Free radicals are reactive oxygen species that constantly circulate through the body and
occur as a side effect of many reactions that take place in the human body. Under normal …

Aging is related to a number of functional and morphological changes leading to
progressive decline of the biological functions of an organism. Reactive Oxygen Species …

Free radicals are chemical species (atoms, molecules, or ions) containing one or more
unpaired electrons in their external orbitals and generally display a remarkable reactivity …

Free radicals are a group of damaging molecules produced during the normal metabolism of
cells in the human body. Exposure to ultraviolet radiation, cigarette smoking, and other …

Overproduction of oxidants (reactive oxygen species and reactive nitrogen species) in the
human body is responsible for the pathogenesis of some diseases. The scavenging of these …

Oxidative stress arises when there is a marked imbalance between the production and
removal of reactive oxygen species (ROS) in favor of the prooxidant balance, leading to …

Abstract “Oxidative stress” as a concept in redox biology and medicine has been formulated
in 1985; at the beginning of 2015, approx. 138,000 PubMed entries show for this term. This …
