Elevated oxidative stress can alter the function of proteins through the reversible oxidation of the thiol groups of key cysteine residues. This study evaluated a method to scan for reversible protein thiol oxidation in tissue by measuring reduced and oxidized protein thiols. It assessed the responsiveness of protein thiols to oxidative stress in vivo using a dystrophic (mdx) mouse model and co...

introduction: the aim of the study was to investigate the effects of curcuma longa (c. longa) extract on adriamycin-induced hepatotoxicity in rat. methods: animals were divided in six groups: control (co), adriamycin (adr), adriamycin with vitamin c (adr+vitc), vitamin c (vit c), c. longa with adriamycin (cl+adr) and without adriamycin (cl-adr). hepatotoxicity was induced by adriamycin 5mg/kg a...

OBJECTIVE Childhood obesity is an important cause of cardiovascular risk with chronic inflammation. Oxidative stress may contribute to the pathogenesis of obesity-related cardiovascular pathologies. We aimed to evaluate thiol/disulphide homeostasis as a novel and sensitive marker of oxidative stress and to evaluate its relationship with some inflammatory and cardiovascular markers in obese chil...

The objective of this study was to determine thiol/disulphide homeostasis (TDH) in infertile cows with subclinical endometritis (SCE). Endometrial cytological samples were collected using a cytobrush diagnose SCE 36 cows. According the results cytology examination, those acute classified as Group I (n = 20) and chronic II 16). A control group formed heifers III 20). Blood taken from each on day...

Aim: EInflammation andoxidative stres play an active role in renal injury that develops after open heart operations as many diseases. There is a balance between oxidants and antioxidant defense mechanisms, the morbidity of cardiac surgery patients, this thought to change depending on factors.Materials Methods: 76 patients scheduled for coronary artery bypass graft were included study. Demograph...

Aim: The accurate diagnosis of acute appendicitis can be achieved by a combination evaluation clinical symptoms, physical examination findings and history taking, but is still challenging for the clinician. Some biochemical markers have been evaluated purpose increasing diagnostic accuracy rate appendicitis. In this study, our aim to evaluate value thiol-disulfide levels IMA, in pediatric patie...

BACKGROUND: The early stage of Copper poisoning is difficult to be clinically diagnosed in sheep and has not been documented clearly yet. OBJECTIVES: To assess biomarkers in predicting early Copper poisoning in sheep, blood samples were collected from several groups of animals from a naturally Copper poisoning occurrence in an industrial region. METHODS: Animals were divided into four experimen...

Introduction The role of oxidative stress in the pathogenesis of psoriasis has been investigated in previous studies with conflicting results. On the other hand, well-established treatments currently used in psoriasis exert their effects via a boost of oxidative stress. Recently, a strong positive association between psoriasis, metabolic syndrome and dyslipidemia has also been described showing...

Objective: Iron is an element, which found in the structure of antioxidant enzymes and has important role inactivation reactive oxygen species. Disruption oxidant-antioxidant balance may be playing a pathogenesis iron deficiency anemia (IDA). Dynamic thiol-disulfide homeostasis (DTDH) serum ischemia-modified albumin (IMA) levels are indicators pro-oxidant/antioxidant status. In this study, we a...

Background & Aim: Free radicals are produced in ischemic processes. Nerve damage caused by free radicals may play a role in neurological diseases and antioxidants are protective activity. Ellagic acid is a polyphenol compound with antioxidant properties which is found in fruits like pomegranate, blackberry, and all types of mulberry. This study aimed to evaluate the effect of 14 days of oral ad...
