background: diabetes mellitus is associated with chronic changes in peripheral arteries because of oxidative stress and insufficient antioxidative defense mechanism. omega-3 fatty acid supplementation could be effective in some diabetes complications; however, polyunsaturated fatty acids may increase lipid peroxidation. this study aimed to determine whether eicosapentaenoic acid alone or in con...
Background and purpose: Diazinon (Dz) is a widely used insecticide. It can cause nephrotoxicity and neurotoxicity by induction of oxidative stress. Edaravone is a drug with antioxidant effect that is used in treatment of acute infraction disorders. In this study we used edaravone for ameliorating diazinon induced kidney and brain damage. Materials and methods: Twenty four male Wistar rats were...
Inflammatory status is observed in patients with chronic renal failure (CRF). The relationship between oxygen free radical production and dialysis could play an important role in protein oxidation. Carbonyl protein plasma level is an important tool in the study of protein stress, and it is related to the arterial intima thickness in the atherosclerosis process. We studied protein oxidative stre...
PURPOSE To analyse if the carbonyl proteins measurement could be validated as a method that allows the identification of an intestinal oxidative stress after ischemia and reperfusion injury. METHODS Twenty-five male Wistar rats (n = 21) weighting 200 to 250 g were divided into three groups. Group I--control (n = 10). Group II--sham (n = 5) and Group III (n = 10) subjected to 60 minutes of int...
Adriamycin is an anthracycline antineoplastic agent whose clinical effectiveness is limited by severe side effects, including cardiotoxicity. A current hypothesis for adriamycin cardiotoxicity involves free radical oxidative stress. To investigate this hypothesis in a model system, we applied the technique of immunochemical detection of protein carbonyls, known to be increased in oxidized prote...
Current limitations in protein structure prediction and design suggest an incomplete understanding of the forces governing protein folding. As such, noncovalent interactions in proteins, particularly hydrogen bonds, have received great attention [1,2]. In common secondary structure patterns like the α-helix and β-sheet, main-chain N–H hydrogen bond donors approach their carbonyl acceptors appro...
During inflammation, the resulting oxidative stress can damage surrounding host tissue, forming protein-carbonyls. The SJL mouse is an experimental animal model used to assess in vivo toxicological responses to reactive oxygen and nitrogen species from inflammation. The goals of this study were to identify the major serum proteins modified with a carbonyl functionality and to identify the types...
