conclusions hemodialysis exacerbates oxidative stress and conformational changes of hb in patients with diabetes on hemodialysis. the frap value can be used as a positive determinant, while pco and hb derivatives can be used as negative determinants of oxidative stress in patients with diabetes. background diabetes is associated with an increased generation of reactive oxygen species (ros), whi...
objective: hexavalent chromium [cr (vi)] compounds are well-known environmental contaminants generated from industrial processes. several studies have reported the harmful effects of cr (vi) on different organs, however, little is known about neurotoxic effects of cr (vi). the aim of this study is to investigate the toxic effects of cr (vi) on pc12 cells. methods: pc12 cells were cultured foll...
BACKGROUND Oxidative stress, an increase in oxidants and/or a decrease in antioxidant capacity, is one of the potential biochemical mechanisms involved in the pathogenesis of nonalcoholic steatohepatitis. We aimed to investigate the total antioxidant response using a novel automated method in nonalcoholic steatohepatitis subjects. As a reciprocal measure, we also aimed to determine total peroxi...
OBJECTIVES To investigate the relationship between lipid levels and oxidative stress index in healthy young adults. METHODS The study was camed out at the Department of Emergency Service, Faculty of Medicine, Cumhuriyet University, Sivas, Turkey, between January 2011 and July 2012. A total of 100 healthy adult volunteers were enrolled in the study. Venous blood samples (10 ml) were collected ...
AIM Evidence that oxidative stress plays a role in the development of bronchopulmonary dysplasia (BPD). There is a close relationship between oxidative stress and inflammation. In this study, it is aimed to investigate influences of hydrocortisone used in the treatment of BPD on anti-oxidant system in preterm infants with BPD. PATIENTS AND METHODS The study enrolled 33 infants with severe BPD...
Abstract Background: Studies show stress was caused by labour can increase oxygen demand and may be involved in oxidative stress. So this study compared indicators of oxidative stress in pregnancy with labor and correlation labor indices with newborn. Methods: In this cross – sectional study in 1386, 60 pregnant women at 38-40 weeks gestation were sampled and drowned 5 cc blood. All of the moth...
Oxidative stress markers in Thoroughbred horses after castration surgery under inhalation anesthesia
Oxidative stress has been reported to occur during surgery. It is important to reduce intraoperative oxidative stress to improve the postoperative prognosis. However, there are no reports regarding oxidative stress related to surgery in horses. In the present study, we measured pre and postsurgical diacron-reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP); the oxid...
BACKGROUND/AIMS Helicobacter pylori infection has been suggested to be associated with atherosclerosis. The issue is still controversial. It is well known that abnormal lipid profile and oxidative stress are related to atherosclerosis and the measurement of carotid intima-media thickness. The aim of this study was to investigate carotid intima-media thickness and oxidative stress along with lip...
Objective: Hepatopulmonary syndrome (HPS) is characterized by vascular dilatation and hyperdynamic circulation, while portopulmonary hypertension (POPH) is characterized by vasoconstriction with fibrous obliteration of the vascular bed. Vasoactive molecules such as nitric oxide (NO) are candidate factors for cirrhotic complications. However, oxidative stress balance is not well characterized in...
BACKGROUND Hemodynamically significant patent ductus arteriosus (hsPDA) leads to injury in tissues/organs by reducing perfusion of organs and causing oxidative stress. The purpose of this study was to evaluate the oxidant/antioxidant status in preterm infants with hsPDA by measuring the total antioxidant capacity and total oxidant status and to assess neuronal damage due to oxidant stress relat...
