The aim of this study was to determine which oxidant–antioxidant blood markers are of interest for a field exercise test (ET) performed on a racetrack. Healthy Standardbred horses (S: n 1⁄4 12) and healthy eventing horses (E: n 1⁄4 12) were investigated. Exercise was monitored by measuring velocity (V), heart rate (HR), and plasma lactate (LA). Whilst maximal LA did not differ (11.8 ^ 0.88 mmol...

background: there are studies that indicated dyshomeostasis of oxidant/antioxidant and trace elements in breast cancer patients, but the data regarding the status of these parameters in various stages of breast cancer are limited. the aim of this study was to highlight the status of these biochemical factors in various stages of breast cancer. methods: fifty-eight breast cancers patients partic...

We aimed to investigate the relation between serum inflammatory markers, 25OHvit-D3 and oxidative stress markers, namely paraoxonase1-arylesterase (PON1-ARE), total antioxidant status (TAS) and total oxidant status (TOS) in 30 male patients with ST-elevation myocardial infarction(STEMI) . There was negative correlation between tumor necrosis factor alpha and ARE; positive correlations between s...

background the molecular mechanism of hepatitis c-virus (hcv) genome-specific pathogenesis remains unclear. oxidative stress is an important pathophysiological mechanism in chronic hcv infection, but its relation to hcv genotypes has not been thoroughly examined. objectives in the present case-control study, the effect of diverse hcv genotypes on oxidative status changes was investigated. patie...

BACKGROUND/AIM Reactive oxygen species play an important role in the pathogenesis of acute pancreatitis (AP) in animal models. Data on the oxidant-antioxidant balance in humans are scanty. The present study was undertaken to evaluate the dynamics of changes in the oxidant-antioxidant balance in the early phase of human AP. METHODS 74 consecutive patients with acute biliary pancreatitis (16 wi...
