In this study, capsaicin was administered to rats with experimental hypothyroidism. İt aimed determine the changes in plasma levels of thiobarbituric acid reactive substances (TBARS), which are indicators oxidative stress, and total antioxidant capacity (TAS), is one components defence mechanisms. A 32 healthy male Wistar Albino weighing 300-350 g, approximately 12 weeks old, were used as anima...

In this study, we measured free radicals and thiobarbituric acid-reactive substances (TBARS) in hepatocellular carcinoma and in non-cancerous liver parenchyma. There was a higher concentration of free radicals in malignant tissue than in non-cancerous tissue. In contrast, the level of TBARS was significantly (P < 0.01) lower than non-cancerous liver parenchyma. These paradoxical results suggest...

BACKGROUND/OBJECTIVES Isoflavones are widely believed to be beneficial to human health, in relation to their antioxidant potentials. Exercise can cause an imbalance between reactive oxygen species (ROS) and antioxidants. This study was conducted in order to investigate the ability of isoflavones in amelioration of oxidative stress induced by exercise. MATERIALS/METHODS Male Sprague-Dawley rat...

The objective of this work was to evaluate the use of a direct analysis technique (SIFT-MS) to measure the lipid oxidation process in beef meat packed under high oxygen atmosphere and compare it to conventional techniques such as gas chromatography-mass spectrometry analysis and TBARS values. Meat samples from two suppliers were selected and packaged under the same atmosphere conditions. The fa...

Procyanidins, which are natural antioxidants and antimicrobials found in grapes, enhance the quality and extend the shelf life of meat. We explored the effects of edible films incorporating procyanidins on pork loin stored for various times. Procyanidins (0, 0.1, and 0.3%, w/w) were incorporated into the edible films. We assessed meat color, pH, levels of volatile basic nitrogen (VBN) and 2-thi...

BACKGROUND Obesity leads to an increase in inflammation and insulin resistance. This study determined antioxidant activity of flaxseed and its role in inflammation and insulin resistance in obese glucose intolerant people. METHODS Using a randomized crossover design, nine obese glucose intolerant people consumed 40 g ground flaxseed or 40 g wheat bran daily for 12 weeks with a 4-week washout ...

Skinless breast fillets were harvested from broilers fed with 0, 0.25, 0.5, or 1.0% conjugated linoleic acid (CLA) for 3 weeks. Fillets were either vacuum or aerobically packaged, then irradiated at 0 or 3.0 kGy using a Linear Accelerator. Breast fillets were analyzed for thiobarbituric acid reactive substances (TBARS), volatile profiles, and color at 0 and 7 days of storage at 4°C. Dietary CLA...

Hyperglycemia exerts toxic effects on the pancreatic beta-cells. This study investigated the hypothesis that the common antidiabetic drugs glibenclamide and metformin, in combination with tualang honey, offer additional protection for the pancreas of streptozotocin (STZ)-induced diabetic rats against oxidative stress and damage. Diabetes was induced in male Sprague Dawley rats by a single dose ...

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 ...

The aim of the paper was to study the effect of ascorbic acid (vitamin C) and ethanol on the level of thiobarbituric acid reactive substances (TBARS) in the brain, liver, lungs and blood serum of inbred albino BALB/c mice. Sixty male mice divided into 4 groups were used for the study; the mice in each group were injected intraperitoneally (i.p.): Group 1--control, saline; Group 2--H2O2 and FeSO...
