1. The formation of thromboxane B, and malondialdehyde was studied in human plateletrich plasma, in gel-filtered platelets and in bovine platelet microsomes. 2. Exogenous sodium arachidonate was converted into thromboxane B, and malondialdehyde in a concentr ation-dependent manner. Pre-incubation of platelets with aspirin inhibited the production of both thromboxane B, and malondialdehyde, alth...

BACKGROUND Emerging science has shown the effect of oxidation products and inflammation on atherogenesis and carcinogenesis. Cooking hamburger meat can promote the formation of malondialdehyde that can be absorbed after ingestion. OBJECTIVE We studied the effect of an antioxidant spice mixture on malondialdehyde formation while cooking hamburger meat and its effects on plasma and urinary malo...

Malondialdehyde (MDA) has become a well-established biomarker for oxidative stress. The most commonly used way to determine urinary MDA levels is the thiobarbituric acid (TBA) assay, which suffers from several drawbacks. In this manuscript, we describe a novel derivatization strategy for the highly sensitive and selective fluorescence-based determination of MDA in urinary samples. The methodolo...

OBJECTIVE Malondialdehyde-acetaldehyde (MAA) adducts are a product of oxidative stress associated with tolerance loss in several disease states. This study was undertaken to investigate the presence of MAA adducts and circulating anti-MAA antibodies in patients with rheumatoid arthritis (RA). METHODS Synovial tissue from patients with RA and patients with osteoarthritis (OA) were examined for...

simultaneous exposure of highly-used chemical and physical agents are expected to happen in many occupations. in the present study the impact of simultaneous exposure to noise and formaldehyde on oxidative stress in blood and liver tissue of rat was investigated. animal study was conducted in the school of public health, shahid beheshti university of medical scineces, tehran, iran in 2013. a to...

The aim of study was to assay serum copper, zinc and lipid peroxidation levels in pregnant women with and without preeclampsia. There were significant differences between systolic, diastolic blood pressures and copper, Cu/Zn ratio and malondialdehyde among two groups. There were significant differences in weight, pre-pregnancy body mass index, systolic, diastolic blood pressures and copper, Cu/...
