Oxidative stress has been identified as the root cause of the development and progression of several diseases. Supplementation of exogenous antioxidants or boosting endogenous antioxidant defenses of the body is a promising way of combating the undesirable effects of reactive oxygen species (ROS) induced oxidative damage. Plants have an innate ability to biosynthesize a wide range of non-enzyma...

Reactive oxygen species (ROS), including superoxide anion, hydrogen peroxide, and hydroxyl radical, can be formed as normal products of aerobic metabolism and can be produced at elevated rates under pathophysiological conditions. Overproduction and/or insufficient removal of ROS result in significant damage to cell structure and functions. In vitro studies showed that antioxidants, when applied...

Active oxygen species are produced as a consequence of normal aerobic metabolism. Of these, free radicals are usually metabolized or inactivated in vivo by a team of antioxidants. Individual members are a trained team fighting antioxidants to prevent the generation of ROS, destroy or oxidizing potential of capture. In terms of physiological oxidative stress, induced tissue attack is minimal. A ...

Development of organ dysfunction associated with sepsis is now accepted to be due at least in part to oxidative damage to mitochondria. Under normal circumstances, complex interacting antioxidant defense systems control oxidative stress within mitochondria. However, no studies have yet provided conclusive evidence of the beneficial effect of antioxidant supplementation in patients with sepsis. ...

To the Editor: Blanco-Colio et al1 showed that a fat-enriched breakfast increased the activation of the transcription factor nuclear factor-kB in peripheral blood mononuclear cells of normal subjects, an effect prevented by antioxidants present in red wine. We compared the effects of a high-fat meal and a high-carbohydrate meal (pizza), with or without dietary antioxidants, on the levels of sol...

Background Oxidative stress, which refers to cellular damage caused by reactive oxygen species (ROS), has been implicated in many disease processes. The Age-Related Eye Disease Study (AREDS) showed that daily intake of a combination of the antioxidants beta carotene, vitamins C and E, zinc and copper may retard the progression of age related macular degeneration by reducing ROS [1]. We investig...

Free radicals are well known for playing a dual role in our body- deleterious as well as beneficial. It includes a metabolic pathway for its generation. Oxidative stress in our body occurs due to excessive generation of free radicals and reduced level of antioxidants, but at low concentrations, these radicals help to perform normal physiological functions of the body. Scientific evidence sugges...

Cisplatin had shown anti-leishmanial effect both in vitro and in vivo against murine visceral leishmaniasis. The present study was designed to evaluate the effect of cisplatin on gonads of Leishmania donovani infected BALB/c mice. In drug treated animals, mild reduced spermatogenesis was observed but when antioxidants were supplemented along with cisplatin, the morphological characteristics of ...
