Aged garlic extract (AGE) is an odorless garlic preparation containing S-allylcysteine (SAC) as its most abundant compound. A large number of studies have demonstrated the antioxidant activity of AGE and SAC in both in vivo--in diverse experimental animal models associated to oxidative stress--and in vitro conditions--using several methods to scavenge reactive oxygen species or to induce oxidat...

Ascorbic acid (AA) and dehydroascorbic acid (DHA) are known to have protective effects in experimental central nerve system disorder models such as stroke, ischemia, and epileptic seizures. The present study was conducted to examine the protective effect of AA and DHA on kainic acid (KA) neurotoxicity using organotypic hippocampal slice cultures (OHSC). Protective effects of AA and DHA on KA-in...

Under oxidative stress conditions, which are defined as the deterioration of antioxidant and prooxidant balance in organism favor prooxidants, ROS species that trigger formation various diseases occur. The fact these harmful cause damage to biological macromolecules is expressed activity. In this study, Cu(II)‒catalyzed activities pomegranate, apricot, peach, pear juices extracts mint, white te...

The aim of this work is to study the effect of the flavonoids rutin and quercetin on hepatic monooxygenase activities in experimental influenza virus infection (EIVI). EIVI causes oxidative stress in the whole organism. This is confirmed by the rapidly increased concentrations of thiobarbituric reactive substances in influenza-infected mice: lungs - 290%; blood plasma - more than 320%; liver - ...

Albumin represents the predominant circulating antioxidant agent in plasma exposed to continuous oxidative stress and a change in serum albumin structure accounts for its antioxidant properties. Alterations in the redox status of albumin may result in impairments of its biological properties. Alpha-lipoic acid (LA), a naturally occurring thiol compound found in virtually all species, is a poten...

Introduction: The molecular mechanisms involved in pathogenesis of esophageal cancer have been the main concern of several studies. In this study, we aimed to investigate the changes of serum prooxidant-antioxidant balance (PAB) value as a redox index, as well as serum C-reactive protein (CRP) compared to healthy control group. Materials and Methods: In a cross-sectional study, blood samples we...
