Phenylalanine ammonia-lyase (PAL) is the first enzyme involved in the phenylpropanoid pathway and plays important roles in the secondary metabolisms, development and defense of plants. To study the molecular function of PAL in anthocyanin synthesis of Coleus (Solenostemon scutellarioides (L.) Codd), a Coleus PAL gene designated as SsPAL1 was cloned and characterized using a degenerate oligonucl...
Abstract Background and objective: Exposure of red blood cells to oxygen radicals can induce Lipid proxidation, hemoglobin damage and hemolysis of erythrocyte .The present study was designed to determine the alteration of plasma lipid peroxidation and erythrocyte Superoxide Dismutase and Glutathione Peroxidase enzyme activities in stored blood and to find out the quantitative alterations and th...
Excretory-secretory products (ESP) play an important role in the host biochemical defense by means of activities of detoxifying and antioxidant enzymes. The aim of this study was to evaluate praziquantel (PZQ) effects by detection of glutathione S- transferase (GST) and superoxide dismutase (SOD) enzymes activities in ESP samples of Fasciola spp. Fasciola gigantica and Fasciola hepatica a...
study on the histopathologicaland enzymatic relationship in chickens affected bymarek's disease
the aim of the present study was to determine the relationship between histopathological lesions and tissue enzymes in chickens affected by marek's disease.five apparently healthy chickens(as control group)and 25 chickens affected by marek's disease were selected. after consideration of history and gross lesions, tissue samples were collected from kidney, liver, heart, ovary, pectoral...

After consideration of history and gross lesions, tissue samples were collected from kidney, liver, heart, ovary, pectoral muscl...
Abstract Background: Anti oxidative enzymes activity is an important issue in oxidative stress. Most previous researches have dealt with the effect of brief and anaerobic exercise on these enzymes the purpose of this study was to determine the alterations of antioxidant enzymes viz. superoxide desmutase, catalase and glutathione (SOD, CAT, and GPX) activity after endurance training in rat li...
abstract the purpose of this study is twofold: on the one hand, it is intended to see what kind of noticing-the –gap activity (teacher generated vs. learner generated) is more efficient in teaching l2 grammar in classroom language learning. on the other hand, it is an attempt to determine which approach of the noticing-the-gap- activity is more effective in the long- term retention of grammar...
the aim followed in this study was to compare the performance of multiple regression vs neural network models to predict the activity of antioxidant enzymes super oxide dismutase (sod), cat alase (cat), ascorbate pero xidase (apx) and peroxidase (pox) in the shoots of wheat (triticum aestivum), alvand cultivar in a soil polluted with cadmium. the treatments consisted of four levels of cadmium (...
BACKGROUND The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on the activity of superoxide dismutase (SOD) of the host was studied. MATERIAL AND METHODS Last instar larvae of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae at 20 invasive juveniles per insect. At 6, 12, 18, 24 and 36 h after infection a...
The herbicide glyphosate, N-(phosphonomethyl)glycine, induced phenylalanine ammonia-lyase (PAL) activity in the roots of dark-grown maize seedlings. This enzyme induction was shown to precede glyphosate-reduced fresh weight gain in the roots by 24--48 h. Feeding aromatic amino acids with glyphosate further inhibited growth while slightly lowering glyphosate-enhanced PAL activity. Soluble protei...
