Chlorpyrifos, O,O'-diethyl-O-3,5,6-trichloro-2-pyridyl phosphorothionate, exposure in rats caused significant inhibition of acetylcholinesterae activity in different regions of brain and generated oxidative stress as evidenced by increase in the level of thiobarbituric acid reactive substances and decrease in the ratio of reduced to oxidized glutathione in all the three regions of brain. Malond...

The effect of aqueous ethanol (1:1) extract of the calyx of Hibiscus sabdariffa on carbon tetrachloride (CCl4) induced liver damage was investigated. Oral administration of the extract following a single CCl4 dose promoted the healing of oxidative liver damage as determined by serum aminotransferases, ALT, AST, levels and liver thiobarbituric acid reactive substances levels. It appeared from th...

to the TBARS assay. In particular, different aldehydes can be formed in the lipid peroxidation process and aldehydes other than MDA may form chromogenic complexes with TBA, which exhibit similar absorbance or emission wavelengths. Several other biological compounds, including sugars, amino acids and bilirubin, are also reactive towards TBA and form TBA reactive materials which confound the meas...

A thiobarbituric acid (TBA) reaction for measuring lipid peroxidation products was evaluated for interference by several ingredients commonly used in solutions to prepare or analyze tissue homogenates or subcellular organelles. These included sucrose (up to 100 mM final concentration in the assay medium), Tris-maleate (up to 40 mM), imidazole (up to 20 mM), inorganic phosphate (up to 10 mM), an...

The aim of the study was to investigate the levels of lipid peroxidation, and both plasma and erythrocyte antioxidant states in patients with rheumatoid arthritis. The population consisted of 60 subjects divided into two groups, 30 subjects had evidence of rheumatoid arthritis and age and sex matched healthy subjects were studied as controls. The level of plasma and erythrocyte thiobarbituric a...

The aim of the present study was to assess whether BAY 11-7082, a nuclear factor-kappaB (NF- κ B) inhibitor, influences the level of reactive oxygen species (ROS), tumor necrosis factor alpha (TNF- α), and NF- κ B related signaling pathways in the liver. The animals were divided into 4 groups: I: saline; II: saline + endothelin-1 (ET-1) (1.25 μg/kg b.w., i.v.); III: saline + ET-1 (12.5 μg/kg b....

To understand the mechanisms of off-odor production in irradiated meat, the volatile compounds produced from individual fatty acids by irradiation were identified. Nonirradiated oil emulsions prepared with polyunsaturated fatty acids (PUFAs) produced many volatile compounds, but the amounts of volatiles generally decreased after irradiation. Although volatile profiles of fatty acid emulsions we...

The use of colloidal solutions of metals as micronutrients enhances plant resistance to unfavorable environmental conditions and ensures high yields of food crops. The purpose of the study was a comparative evaluation of presowing treatment with nanomolybdenum and microbiological preparation impact upon the development of adaptive responses in chickpea plants. Oxidative processes did not develo...
