The aim of the study was to assess the markers of oxidant-antioxidant status in excess body mass index (BMI) persons with and without the obstructive sleep apnea syndrome (OSAS). In overweight (BMI-1: 25.0-29.9 kg/m(2)) control and OSAS and obese (BMI-2: 30.0-34.9 kg/m(2)) control and OSAS subjects with no acute or chronic disorder the following markers were determined: concentration of plasma ...

chronic ethanol consumption leads to oxidative stress in the heart and erythrocytes of rats. as ziziphus jujuba fruit has been shown to have potent antioxidants, such as flavonoids, we conducted this study to evaluate the effects of aqueous fruit extracts from z. jujuba on rat hearts and erythrocytes following chronic ethanol consumption. twenty-eight male wistar rats were randomly divided into...

BACKGROUND Little is known about differences in amounts of antioxidants or oxidative stress at different stages of knee osteoarthritis. This study investigated the relationship between concentrations of antioxidants, iron and lipid peroxidation in synovial fluid and levels of severity of primary knee osteoarthritis. MATERIALS AND METHODS From 2011 to 2013, 23 patients (mean age, 66.7 ± 7.6 ye...

Oxidative stability of egg and soy lecithin in emulsion was evaluated with two transition metal ions, cupric and ferric ion, at two concentration levels (50 and 500 microM). The effect of pH on lipid oxidation was also examined under these two concentrations for each ion. Egg lecithin (EL) had similar peroxide value (PV) development pattern as soy lecithin (SL) when treated with cupric ion unde...

This study was conducted to improve sensory quality of Jokbal (Korean Pettitoes) made from frozen pig feet by addition of herbal mixture (glasswort, raspberry and Sansa powders). After adding herbal mixture, lipid oxidation (2-thiobarbituric acid values, TBARS), sensory property, and textural property were determined. Herbs were individually added into cooking soup at concentration of 6% (low c...

Recent studies have demonstrated that C-peptide exerts beneficial effects on endothelial function. To investigate the relationship between residual pancreatic C-peptide secretion and endothelial function in patients with well controlled or poorly controlled Type II diabetes, we studied 100 patients with Type II diabetes that were free from diabetic neuropathy. In all patients, insulin resistanc...

During a haemodialysis (HD), because of the contact of blood with the surface of the dialyser, the immune system becomes activated and reactive oxygen species (ROS) are released into plasma. Particularly exposed to the ROS are lipids and proteins contained in plasma, which undergo peroxidation. The main breakdown product of oxidized lipids is the malondialdehyde (MDA). A common method for measu...

The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams' E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 microM). Hepatocytes incubated in the MWE medium without cadmiu...

BACKGROUND The effect of eccentric exercise on the time-course changes in several indices of muscle damage and blood oxidative stress was examined. MATERIALS AND METHODS Isometric torque, delayed-onset muscle soreness, creatine kinase, reduced glutathione (GSH), oxidized glutathione (GSSG), thiobarbituric-acid reactive substances (TBARS), protein carbonyls, catalase, uric acid, bilirubin and ...

OBJECTIVES Previous research on a group of workers occupationally exposed to styrene, ethylene glycol, toluene, p-xylene and their mixture showed elevated levels of the main products of lipid peroxidation: malondialdehyde and 4-hydroxynonenal (MDA+,4-HNE) in plasma [1]. Moreover, an earlier in vitro study indicated a synergistic interaction between styrene and ethylene glycol on lipid peroxidat...
