BACKGROUND The association between the oxidative status and metabolic syndrome (MetS) should be studied in various populations with various oxidative stress-related markers. The aim of this cross-sectional study was to investigate the association between oxidative status, as assessed by the reactive oxygen metabolites (d-ROMs) test, and MetS in asymptomatic Japanese men, in relation to age. M...

Article history: Received on: 20/04/2015 Revised on: 24/05/2015 Accepted on: 19/06/2015 Available online: 27/07/2015 Imbalance oxidative status occurs when oxidative stress is higher in the body due to the production of reactive oxygen species. Thus, antioxidants are needed to counteract the production of free radicals. Reoccurrence of oxidative stress in the lung cells will eventually lead to ...

Background: Cigarette smoke is a major source of free radicals and oxidative stress. With a significant proportion of women still smoking during pregnancy, this common and avoidable exposure has the potential to influence infant oxidative status, which is implicated in the increased propensity for airway inflammation and asthma. The aim of this study was to examine the effects of maternal smoki...

Oxidative stress is the result of the imbalance between reactive oxygen species (ROS) formation and enzymatic and nonenzymatic antioxidants. Biomarkers of oxidative stress are relevant in the evaluation of the disease status and of the health-enhancing effects of antioxidants. We aim to discuss the major methodological bias of methods used for the evaluation of oxidative stress in humans. There...

To this date, the relevance of oxidative stress status in type 2 diabetes patients and in those with chronic alcohol consumption has been subject to numerous controversies in the literature, since various modifications of the oxidative stress markers have been reported in these disorders. In this context, we assessed in the present paper the oxidative stress status, by determining the specific ...

BACKGROUND AND AIMS Nitro-oxidative stress may have pathophysiological consequences. The study aimed to assess the nitro-oxidative stress, the vascular growth factor, and metalloproteinase-9 levels in patients with noncirrohic and cirrhotic portal hypertension. METHODS Patients with noncirrhotic portal hypertension (n=50) and cirrhotic portal hypertension (n=50) from the 3rd Medical Clinic in...

Imbalance between reactive oxygen species generation and antioxidant capacity induces a condition known as oxidative stress which is implicated in numerous pathological processes. In this study we evaluated whether natural zeolites chabazite/phillipsite/analcime may affect the levels of different antioxidant enzymes (gluthatione peroxidase, superoxide dismutase, gluthatione reductase), total an...

The purpose of the present study was to determine the function and oxidative status in kidney and liver using a model of obesity induced by neonatal treatment of rats with monosodium glutamate, and to investigate the association of these metabolic changes with antioxidant enzymes, oxidative stress and NO generation. Methods: neonate male Wistar rats were subcutaneously injected, with monosodium...

Type 2 diabetes mellitus (T2DM) is strongly associated with obesity. The adipose tissue secretes bioactive adipokines leading to low grade inflammation, amplified by oxidative stress, which promotes the formation of advanced glycation end products and eventually leads to dyslipidemia and vascular complications. The aim of this study was to correlate anthropometric, biochemical and oxidative str...

Oxidative stress is a key feature in atherogenesis, since reactive oxygen species (ROS) are involved in all stages of the disease, from endothelial dysfunction to atheromatic plaque formation and rupture. It is therefore important to identify reliable biomarkers allowing us to monitor vascular oxidative stress status. These may lead to improved understanding of disease pathogenesis and developm...
