to find the protective role of exogenous nitric oxide (no) on salinity-stressed rice seedlings, a crd-based factorial experiment with three replications was conducted in agronomy laboratory of the faculty of agricultural sciences, university of guilan, in 2012. the experimental design consisted of healthy and vigorous seedlings of two rice cultivars, khazar and goohar, the last already known as...

In the present study fifty genotypes of Brassica juncea were evaluated for heat stress tolerance in terms of biochemical components, in four day old seedlings. Heat shock was given at 45 degrees C for 4.5 hr and thereafter survival percentage, electrolyte leakage and chlorophyll content were estimated. Tolerant genotypes (10) registered survival greater than 65%, moderately tolerant (20) betwee...

BACKGROUND Oral lichen planus (OLP) is a chronic and inflammation mucosal disease. Reactive Oxygen Species (ROS) and oxidative stress damage might be the cause. Malondialdehyd (MDA), one parameter of lipid peroxidation is appropriate for DNA damage in OLP disease. OBJECTIVE To evaluate antioxidants and oxidative stress parameters in patients with oral lichen planus (OLP) diseases and healthy ...

Triacylglycerol-rich lipoproteins (TGRLP) were isolated from Cu-deficient and control rats. TGRLP from Cu-deficient rats appeared more fluid than those from controls as sensed by the fluorescence anisotropy of 1,6-diphenyl-1,3,5-hexatriene (DPH). This high fluidity was related to a low cholesterol:phospholipid ratio and high triacylglycerol content in these lipoproteins. TGRLP from Cu-deficient...

in order to find a prophylactic supplementation for individuals who are at risk of exposure to ionizing radiation, we attempted to evaluate the effect of vitamin e (vit-e), a biological free radical scavenger, on restoration of hepatic lipid peroxidation (lpo) and lipid profile (lp) changes induced by sublethal g- radiation in balb/c mice. the concentrations of cholesterol and phospholipid were...

amodiaquine is an antimalarial drug used in the prophylaxis and treatment of this disease. however, hepatotoxicity as a life‑threatening adverse effect is associated with its clinical use. we evaluated amodiaquine-induced toxicity in isolated rat hepatocytes as an in vitro model for studying drug‑induced hepatotoxicity. this study attempts to investigate the protective effects of taurine and n-...

this study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet.stocking density was selected 5 (group a), 15 (group b), 25 (group c) kg fish m−3.tukey’s multiple comparison test showed insignificant differences between measured size/weight measurement and condition fac...

Abstract Developing and applying a novel plant growth–promoting agent (PGPA; micronutrient-amino acid chelated compound developed from autolysis yeast cells) in alleviating salt stress toxicity can be the best alternative option environmentally economically. High-performance liquid chromatography (HPLC) showed that assembled PGPA is rich nucleobases than extract (> 56-fold). This study, as f...

Drought is one of the main abiotic stress factor that limits plant growth and development. effects on Borago officinalis L. (borage) plants in terms physiological antioxidant responses have been evaluated this study. In parallel with purpose, relative rate (RGR), leaf water content (RWC), osmotic potential, chlorophyll fluorescence (Fv/Fm), lipid peroxidation, hydrogen peroxide (H2O2) level, su...
