Malondialdehyde (MDA), used as an oxidative stress marker, is commonly assayed by measuring the thiobarbituric acid reactive substances (TBARS) using HPLC, as an indicator of the MDA concentration. Since the HPLC method, though highly specific, is time-consuming and expensive, usually it is not suitable for the rapid test in large-scale environmental epidemiologic surveys. The purpose of this s...

BACKGROUND Thiobarbituric reacting substances (TBARS) are markers of lipoperoxidation. The best-known specific TBARS is malondialdehyde (MDA). Results from our previous studies have shown that TBARS can be measured in saliva and are increased in patients with gingivitis. Whether MDA is the main TBARS in saliva from patients with altered parodontal status is unknown. Aim. To observe the relation...

BACKGROUND Pregnancy induced hypertension (PIH) is a state of extremely increased oxidative stress. Hence, research and test of role and significance of oxidative stress in hypertensive disturbance in pregnancy is very important. AIM Aims of this research were to determine a level of thiobarbituric acid reactive substance (TBARS) as oxidative stress marker in blood of pregnant woman with preg...

BACKGROUND Circulating thiobarbituric acid-reacting substance (TBARS) levels, a marker of systemic oxidative stress, are predictive of cardiovascular events. However, they has not been evaluated in Japanese, especially with regard to the factors that contribute to the changes in circulating TBARS levels. We investigated the cross-sectional and longitudinal relationships between circulating TBAR...

BACKGROUND Salivary thiobarbituric acid reacting substances (TBARS) have been previously shown to correlate with the impairment of gingival tissue. Although the details on the origin and the composition of this heterogeneous group of compounds in saliva are unknown, the potential clinical usefulness makes necessary the studies of factors influencing the salivary TBARS levels. AIM To observe t...

Lipid peroxidation in feed can negatively affect animal health, growth performance, and meat quality. The objective of this study was to determine the lipid peroxidation level in corn dried distillers grains with solubles (DDGS) samples from 31 U.S. ethanol plants and compare results with a corn sample obtained from a corn processing plant. Lipids from each sample were extracted with hexane and...

Systemic oxidative stress plays a role in many degenerative diseases. Although regular physical activity has been known as the most effective nonpharmacological intervention to alleviate the oxidative stress, the beneficial effect varies between individuals. We investigated whether NADPH oxidase p22phox gene C242T and A640G polymorphisms are associated with systemic oxidative stress level respo...

INTRODUCTION Salivary TBARS are a potential marker of oxidative stress in the oral cavity. Previous studies have found increased levels of salivary TBARS in various diseases. The aim of this study was to assess the variability of salivary TBARS in both genders. SUBJECTS & METHODS Saliva samples from thirty-eight healthy volunteers (18F & 20M) were collected every day during 30 day period. TBA...
