iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
PURPOSE Oxidative damage plays an important role in atherosclerosis development. Statin drugs have anti-oxidant properties, but the clinical value of their antioxidant properties remains unclear. In this study, our aims were: (1) to assess the anti-oxidant effects of statins in patients with coronary artery disease (CAD) using a newly developed valid measure of total oxidant and anti-oxidant ca...
Oxidative stress has been suggested to contribute to the pathophysiology of schizophrenia. Increased oxidative stress is the result of either an increased production of free radicals or a depletion of the endogenous antioxidants. However, whether this imbalance of oxidant-antioxidant status in schizophrenia is integral to disease itself or the effect of antipsychotic drugs is not clearly unders...
background: to attain whether the effects of low and high doses of estrogen progesterone luteinizing hormone (lh) and follicle stimulating hormone (fsh) in acute and chronic administration were related to oxidant and antioxidant parameters in rat uterine tissue as well as cyclooxygenase-1 (cox-1) activity. materials and methods: acute and chronic administration of estrogen (1 and 5 mg/ kg) prog...
background : gliomas are the most common primary brain tumors of the central nervous system. among a number of different bio-molecular events, molecular connections between oxidative stress pathways and their development is prevalent. oxidative stress is the consequence of an imbalance between pro-oxidant factors and antioxidant defense. this imbalance may lead to dna damage and changes in grow...
BACKGROUND Portacaval shunting in rats produces a reduction of hepatic oxidant scavenging ability. Since this imbalance in hepatic oxidant/antioxidant homeostasis could coexist with systemic changes of oxidant stress/antioxidant status, plasma oxidants and antioxidant redox status in plasma of portacaval shunted-rats were determined. RESULTS Male Wistar male: Control (n = 11) and with portaca...
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
Background: The etiology of psoriasis, a chronic inflammatory skin disease, has not been elucidated. However, Oxidant / antioxidant imbalance is suspected.The aim of this study was to evaluate oxidant / antioxidant status in psoriatic patients.Method: forty two psoriatic patients and 42 age and sex matched controls were recruited for this study. Serum total antioxidant ...
Nephrotic patients show various abnormalities in protein kinetics. Plasma albumin levels and the total plasma albumin pool are reduced. Nephrotic syndrome is a consequence of an imbalance between oxidant and anti-oxidant activity. Oxidative damage has been proposed as one of the possible mechanism involved in the Nephrotic syndrome. Therefore, this study was carried out to investigate oxidant a...
BACKGROUND The aim of this study was to investigate the levels of oxidative stress including total oxidant status, total antioxidant status, and paraoxonase activity in patients with a diagnosis of acute appendicitis. METHODS Seventy-three patients who underwent surgery with a preoperative diagnosis of acute appendicitis (Group I) were included into the study. The control group (Group II) con...
