Total antioxidant status in plasma of breast cancer patients in relation to ERβ expression
AIM OF THE STUDY The aim of this pilot study was to evaluate the plasma total antioxidant capacity (TAS) in breast cancer patients in relation to ERβ expression. MATERIAL AND METHODS The study group consisted of newly diagnosed consecutive female breast cancer patients (n = 41) and controls (n = 28) randomly selected from women with benign breast disease. TAS was determined with the ABTS reag...
متن کاملMicronutrients: oxidant/antioxidant status.
Potentially damaging species (reactive oxygen, nitrogen and chlorine species) arise as by-products of metabolism and as physiological mediators and signalling molecules. Levels of these species are controlled by the antioxidant defence system. Several components of this system are micronutrients (e.g. vitamins C and E) or are dependent upon dietary micronutrients (e.g. CuZn and Mn superoxide di...

متن کاملLipid peroxidation and antioxidant status in patients with breast cancer.
INTRODUCTION The present study was undertaken to evaluate the status of lipid peroxidation and antioxidants as biomarkers in human plasma. METHODS The extent of lipid peroxidation as evidenced by the formation of thiobarbituric acid reactive substances (TBARS) and conjugated dienes (CD) as well as the status of the antioxidants superoxide dismutase (SOD), catalase (CAT), reduced glutathione (...
متن کاملSerum oxidant/antioxidant status in patients with Behçet's disease.
The aims of this study were to assess whether the increased oxidative stress in affected tissues is reflected by serum lipid peroxidation and to check for alterations in serum levels of extracellular antioxidants and antioxidant enzyme activities in patients with Behcet's disease (BD). Serum malondialdehyde (MDA) and ceruloplasmin (Cp) levels and CuZn-superoxide dismutase (CuZn-SOD) and glutath...
