Abstract 'Reactive oxygen species'(ROS) is a generic term that defines a wide variety of
oxidant molecules with vastly different properties and biological functions that range from …

Oxidative stress is a component of many diseases, including atherosclerosis, chronic
obstructive pulmonary disease, Alzheimer disease and cancer. Although numerous small …

Abstract 'Reactive oxygen species'(ROS) is an umbrella term for an array of derivatives of
molecular oxygen that occur as a normal attribute of aerobic life. Elevated formation of the …

A physiological level of oxygen/nitrogen free radicals and non-radical reactive species
(collectively known as ROS/RNS) is termed oxidative eustress or “good stress” and is …

Superoxide dismutases (SODs) are universal enzymes of organisms that live in the
presence of oxygen. They catalyze the conversion of superoxide into oxygen and hydrogen …

Hydrogen peroxide emerged as major redox metabolite operative in redox sensing,
signaling and redox regulation. Generation, transport and capture of H 2 O 2 in biological …

Nonalcoholic fatty liver disease (NAFLD) has emerged as the most common chronic liver
disease worldwide and is strongly associated with the presence of oxidative stress …

Oxidative stress is two sided: Whereas excessive oxidant challenge causes damage to
biomolecules, maintenance of a physiological level of oxidant challenge, termed oxidative …

Oxidative stress is a normal phenomenon in the body. Under normal conditions, the
physiologically important intracellular levels of reactive oxygen species (ROS) are …

BACKGROUND: With increasing evidence that hydroperoxides are not only toxic but rather
exert essential physiological functions, also hydroperoxide removing enzymes have to be re …
