Among the numerous chemicals discharged into the surrounding environment, bisphenol A (BPA) and octylphenol (OP) have been shown to increase oxidative stress in body by disturbing the prooxidant/antioxidant balance of cells. Cinnamon aqueous extract (CAE) is a natural product rich in polyphenolic compounds that have antioxidant activity. This study was designed to investigate the protective eff...

We have read with interest the work by Lesgards et al. (1) on the effect of different lifestyle factors on their test system, which measures the resistance of red blood cells to an oxidative challenge. Their study showed that psychologic stress is a major factor influencing antioxidant status. This finding encouraged us to share our experiences of a earlier study that resulted in similar conclu...

Pregnancy in insulin-dependent diabetes mellitus is associated with a greater incidence of fetal abnormality. Animal studies suggested that increased free-radical production and antioxidant depletion may contribute to this risk. The objective of this work was to evaluate oxidative stress and antioxidant capacity in hypertensive, diabetics, and healthy control women during labor. Simultaneous de...

the aim of present study was to investigate whether food restriction combined with exercise training could attenuate the oxidative stress and promote angiogenesis in a rat model of heart failure. 50 male wistar rats weighing 250-300 g were randomly divided into 5 groups including: 1) sham; they were fed ad libitum food, n=10. 2) heart failure group; 3) exercise group; they run on a treadmill 5 ...

Platonin (4,4'-dimethyl-3,3'-di-n-heptyl-8-[2-(4methyl-3-n-heptylthiazole)] -2,2'-dicarbocyanine diiodine) is one of the photosensitive trithiazolepentamethine cyanine dyes. Visible light (VL)-promoted photodegradation products of platonin in an aqueous environment were identified as 3-heptyl4-methylthiazoline-2 -carbaldehyde (1), tetradecane-7-thiol (2), 1-nonene (3), heptylamine (4), 3-heptyl...

and represent an essential part of aerobic life and our metabolism. They are continuously produced by the body’s normal use of oxygen such as respiration and some cell mediated immune functions. Naturally, there is a dynamic balance between the amount of free radicals generated in the body and antioxidants to quench and/or scavenge them and protect the body against their deleterious effects. Th...

Oxidative stress is present in the liver of humans with steatosis and nonalcoholic steatohepatitis (NASH) and is a plausible mediator of cellular injury, inflammatory recruitment, and fibrogenesis. CYPs 2E1 and 4A are the microsomal oxidases involved with fatty acid oxidation. Both enzymes can reduce molecular oxygen to produce prooxidant species, which, if not countered efficiently by antioxid...

Background. Peptic ulcer disease has a leading place in the overall structure of digestive diseases: its prevalence is 6.00–10.0 % population developed countries, and mortality ranges from 6 to 9.7 per 100 thousand population. An important etiological factor this pathology neuropsychological background, prima­rily stress, which under repeated exposure becomes initiating physiological imbalance ...

Introduction: the imbalance between formation of reactive oxygen species (ROS) and ability cells to neutralize them is characterized as oxidative stress occurs in almost any pathological condition. Reactions convert ethanol acetic acid are accompanied by an increase ROS production. Given prevalence alcohol abuse contribution development conditions, we formulated aim our work: assess impact chro...
