Introduction Liver function is affected during ischemia/reperfusion (IR). The current state of knowledge about liver aging processes during IR is incomplete. We evaluated the effects of aging on liver structure and function under IR conditions. Material and methods Animals were divided into control (C-2) and ischemia/reperfusion (IR-2) groups of young rats (2-4 months old) and C-12 and IR-12 ...
Subacute toxicity study of acetamiprid was undertaken in 72 female Wistar rats randomly divided into four groups (each consisting of 18individuals). Acetamiprid was administered orally @ 0, 25, 100 and 200 mg/kg of body weight to rats of Groups 1, 2, 3 and 4 respectively. Group 1 served as control. Calcium, sodium, potassium, chloride, zinc, copper, iron and cobalt were significantly increased ...
background and aims: flavonoids as polyphenolic naturally occurring compounds have antioxidant activity. there is increasing evidence suggests that flavonoids may affect the activity of enzymes. paraoxonase 1 is calcium - dependent enzyme that is present in high density lipoproteins. this enzyme has an important role in the prevention of low density lipoprotein oxidation. we investigated the ef...
Introduction: Obesity and cardiovascular disease are among the leading causes of mortality in the world. The aim of the present study was to determine the effect of aerobic training on some antioxidant and cardiac oxidative stress in male rats with two types of normal and cholesterol-rich diet. Materials and Methods: 40 male Wistar rats randomly divided into four groups of normal-control...
Antioxidant properties of ghrelin have been demonstrated in recent studies. In the present study, theeffects of chronic administration of ghrelin on the motility and plasma membrane integrity of rat spermatozoa during incubation at 37ºC were investigated. Thirty 45-day-old male Wistar rats were divided into control and treatment groups. Rats in the treatment group were daily injected subcutaneo...
most specialists in the field of foreign language teachingconsiderreading skill as an interactive process between the reader’s prior knowledge and the text.accordingly, the activation of prior knowledge for an effective comprehension is very important. it is generally agreed that the pre-reading phase is the stage where this type of interaction and activation may be enhanced throughcertain stra...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Background and purpose: Glycation products, oxidative stress, and inflammation contribute to the development of diabetic nephropathy (DN) due to the elevation of transforming growth factor-β1 (TGF-β1). This study aimed at investigating the effect of Cysteine (Cys) on TGF-β in DN rat model. Materials and methods: In this experimental study, 40 male Wistar rats were randomly divided into four g...
the purpose of the present study was to determine the effect of four weeks of detraining after 12 weeks of continuous and intermittent aerobic training on high sensitive c-reactive protein (hs-crp) in rats (325.6±4.93 grams and 21 months old and their fertility period expired 3 months ago). for this purpose, 80 female wistar rats with strain 14848 were prepared and divided into three groups: co...
Background: Margarine contain trans fatty acids as major sources of dietary free radicals, and oxidative stress. Effect of oral administration of margarine on hepatic enzyme was investigated in Wistar rats. Methods: Thirty six (36) adult Wistar rats were uniformly divided into three groups of control , margarine 15% and 20%, twelve rats in each groups (6males & 6 females). Margarine was add...
