The aim of this study was to preserve the quality and prevent colour, lipid protein oxidation in chicken breast fillet (pectoralis major muscle) during storage. For purpose, modified atmospheres (MA) with four different gas mixtures (vol. %) oxygen (O2 ), carbon dioxide (CO2 ) nitrogen (N2 were used: free (0: 20: 80), low (20: 60), medium (40: 40), high MA (70: 10). After 9 days storage a refri...

BACKGROUND Propolis has been proposed to be protective on neurodegenerative disorders. To understand the neuroprotective effects of honeybee propolis, glutamine synthetase (GS) activity, nitric oxide (NO), thiobarbituric acid reactive substances (TBARS) and total antioxidant status (TAS) were studied in different brain regions-cerebral cortex (CC), cerebellum (CB) and brain stem (BS) of rats su...

Oxidative stress represents a situation where there is an imbalance between the reactive oxygen species (ROS) and the availability and the activity of antioxidants. This balance is disturbed by increased generation of free radicals or decreased antioxidant activity. It is very important to develop methods and find appropriate biomarkers that may be used to assess oxidative stress in vivo. It is...

Chronic ethanol consumption leads to oxidative stress in the heart and erythrocytes of rats. As Ziziphus jujuba fruit has been shown to have potent antioxidants, such as flavonoids, we conducted this study to evaluate the effects of aqueous fruit extracts from Z. jujuba on rat hearts and erythrocytes following chronic ethanol consumption. Twenty-eight male Wistar rats were randomly divided into...

The relationship between serum ascorbic acid (AA) and diabetic macroangiopathy was studied. Fifty-six patients with noninsulin-dependent diabetes mellitus were examined, together with 20 healthy controls matched for age against the diabetes patients. Aortic pulse wave velocity (PWV) was taken as an index of the severity of atherosclerosis. The level of serum AA in diabetic patients was signific...

Salinity is affecting plant growth and development. Low concentration of hydrogen peroxide (H2O2) has shown to be effective against various stress factors. In this study, effect different H2O2 priming methods on growth, physiological biochemical parameters in three wheat varieties (NKÜ Lider, Sultan-95, Tosunbey) under salt were investigated. Salt (0 160 mM NaCl) was applied gradually 100 µM (-...

Objective: The aim of this study was to evaluate the effects of pulmonary rehabilitation on oxidative stress biomarker (Thiobarbituric acid substances “TBARS”) and antioxidant enzymes activities (superoxide dismutase “SOD”, glutathione peroxidise “GPx” and catalase “CAT”) in patients with chronic obstructive pulmonary disease (COPD) compared to healthy subjects. Material and Methods: The study ...

Biochemical, genetic, enzymatic and molecular approaches were used to demonstrate, for the first time, that tellurite (TeO(3) (2-)) toxicity in E. coli involves superoxide formation. This radical is derived, at least in part, from enzymatic TeO(3) (2-) reduction. This conclusion is supported by the following observations made in K(2)TeO(3)-treated E. coli BW25113: i) induction of the ibpA gene ...

Objective(s): Quinolinic acid (QA)-mediated excitotoxicity has been widely used as a model for studying neurodegenerative disorders. Recent studies suggested that saffron (Crocus sativus) or its active metabolite, i.e. safranal, exerts pharmacological actions on central nervous system including anxiolytic, anticonvulsant, and neuroprotective properties. The present study aimed to investigate th...

Glasswort (Salicornia herbacea L.) is a halophyte plant known to contain high contents of minerals and phytochemicals. The purpose this study was investigate the effect fermented glasswort on gut health in D-galactose (D-gal)-induced aging rats. Forty rats were randomly divided into five groups: control (CON), D-gal alone (CD), plus fructooligosaccharide as positive (FOS, 400 mg/kg), low dose (...
