INTRODUCTION It is well established that soy protein diets as well as aerobic exercise could promote antioxidant capacity and consequently reduce free radicals overproduction on brain. However, little is know regarding to the high-protein diets and high intensity exercise on oxidative stress production. The aim of this study was to analyse the effects of high-protein diets and high-intensity ex...

Mud crab ( Scylla paramamosain ) fed five different diets with varying concentrations of guava leaf aqueous extract (0 mg·kg –1 , 80 160 320 and 640 for 30 days. crabs in the guava-leaf groups outperformed control group terms survival rates (SR), weight gain (WGR), specific growth (SGR). When compared to group, mud had significantly higher levels lipase (LPS), pepsin, lysozyme (LZM), superoxide...

BACKGROUND The aim of this study was to evaluate the plasma concentrations of malondialdehyde (MDA) and nitric oxide (NO) and the plasma activities of oxidant and antioxidant enzymes in patients with IBS. MATERIAL/METHODS A total of 36 patients with IBS were included in the study. Thirty-five healthy subjects were selected to form the control group. Superoxide dismutase (SOD), catalase (CAT),...

BACKGROUND Cerebrovascular accident is an important cause of death in patients with chronic renal failure. METHODS This study evaluated the interference of low-dose urokinase in peritoneal dialysis solution on uremic serum superoxide dismutase (SOD), malondialdehyde (MDA), nitric oxide (NO) and endothelin (ET) dynamics in patients with a cerebral infarction complicated by uremia. RESULTS Bo...

Excess superoxide has been implicated in pulmonary hypertension (PH). We previously found lung overexpression of the antioxidant extracellular superoxide dismutase (EC-SOD) attenuates PH and pulmonary artery (PA) remodeling. Although comprising a small fraction of total SOD activity in most tissues, EC-SOD is abundant in arteries. We hypothesize that the selective loss of vascular EC-SOD promot...

Synthesis of gold nanoparticles exhibition wide range bioactivities and was conventionally used for the remedy numerous disorders. Our study aims to measure gastroprotective effect synthesized on absolute ethanol-induced stomach ulceration in rats. The rats were noticeably administered with two doses (175 ppm 350 ppm) alcohol showed a significant improvement adverse ethanol-produced damage as c...

In this study, effect of different levels of dietary protein (25, 35 and 45 per cent) and water salinity (0-3, 12-15 and 32-35 ppt) on antioxidant enzymes of white leg shrimp (Penaeus vannamei) was studied. 324 P.vannamei (with mean weight±SE: 5.55 ± 0.18 gr) were randomly distributed in twenty seven tanks. Experimental shrimps were fed by formulated diets for 56 days and at the end of the expe...

Ischemia reperfusion injury (IR injury) is a common problem in clinical conditions. Researches have frequently revealed that ATP- sensitive potassium (KATP) channels and nitric oxide plays a role in protection against ischemic injury in skeletal muscle. The present study aimed at evaluating the possible link between this two pathways. Sixty-eight male wistar rats, were pretreated with saline, d...
