Oxidative stress is implicated in the death of dopaminergic neurons in Parkinson's disease and in the 1-methyl-4-phenyl-1,2,3, 6-tetrahydropyridine (MPTP) model of Parkinson's disease. Oxidative species that might mediate this damage include hydroxyl radical, tyrosyl radical, or reactive nitrogen species such

To test the hypothesis that kwashiorkor is associated with increased oxidative stress, urinary concentrations of 2 oxidized amino acids, o,o '-dityrosine and ortho -tyrosine, were measured by gas chromatography-mass spectrometry. Children with kwashiorkor, with or without infection, had a 3-

The sensitive assay method was developed for a parallel, rapid and precise determination of the most prominent oxidative stress biomarkers: 8-iso-prostaglandin F(2α) a lipid oxidation biomarker, o-tyrosine an amino acid oxidation biomarker and 8-hydroxy-2'-deoxy-guanosine a nucleic acid oxidation biomarker. The

An HPLC assay method and an LC-MS method were used to study the Udenfriend reaction and its variations by using phenylalanine as the hydroxylation substrate. The results indicate that (1). citric acid can replace EDTA as the promoter for the

We have examined the effect of short-term triiodothyronine (T3) administration on reactive oxygen species (ROS) generation by leukocytes in 9 euthyroid subjects. At a dose of 60 microg/d orally for 7 days, T3 induced a significant increase in ROS generation
