In aerobes, oxygen is essential for maintenance of life. However, incomplete reduction of
oxygen leads to generation of reactive oxygen species. These oxidants oxidise biological …

There is increasing evidence that reactive oxygen species (ROS) are not only toxic but play
an important role in cellular signalling and in the regulation of gene expression. We, here …

Androgens are essential for the development and maintenance of male reproductive tissues
and sexual function and for overall health and well being. Testosterone, the predominant …

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

Reactive oxygen species (ROS) have deleterious or beneficial effects; this dual nature of
ROS means that ROS act as intracellular signaling molecules and as defense mechanisms …

Oxidative stress is an important pathophysiological component of airway diseases such as
asthma and chronic obstructive pulmonary disease (COPD), which cause significant …

Reactive oxygen species (ROS) are oxidizing agents amply implicated in tissue damage.
ROS production is inevitably linked to ATP synthesis in most cells, and the rate of production …

Aging can be defined as a progressive decline in the ability of the organism to resist stress,
damage, and diseas. Although there are currently over 300 theories to explain the aging …

Reactive oxygen species (ROS) is a collective term used for oxygen-derived free radicals
(superoxide, hydroxyl radical, nitric oxide) and non-radical oxygen derivatives of high …
