DJ-1, the causative gene of a familial form of Parkinson's disease (PD), has been reported undergo oxidation preferentially at the 106th cysteine residue (Cys-106) under oxidative stress. Recently, it has been found that the levels of oxidized DJ-1 in erythrocytes of unmedicated PD patients are markedly higher than those in medicated PD patients and healthy(More)
BACKGROUND Free radicals and lipid peroxidation are thought to be related to the vasospasm generation after subarachnoid hemorrhage (SAH). Plasma platelet-activating factor-acetyl hydrolase (PAF-AH) degrades phospholipids with an oxidatively modified fatty acyl chain. OBJECTIVE To compare plasma PAF-AH activity and free forms of biomarker of lipid(More)
Lipopolysaccharide (LPS) induces host inflammatory responses and tissue injury and has been implicated in the pathogenesis of various age-related diseases such as acute respiratory distress syndrome, vascular diseases, and periodontal disease. Antioxidants, particularly vitamin E, have been shown to suppress oxidative stress induced by LPS, but the previous(More)
