abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...

To evaluate effects of different salinity levels on activity of antioxidant enzymes (CAT, APX and GPX) and osmotic components (carbohydrate and proline) in two sorghum genotypes, an experiment was conducted as completely randomized factorial design with three replications in Zabol university in 2007. Three levels of salinity control (0), 100 and 200 mM NaCl and two sorghum genotypes (Payam and ...

To study the effects of water stress on compatibility metabolites and the antioxidant enzyme activities of wheat variety trial a factorial experiment was conducted in a completely randomized design in 1393. The experiment consisted of three levels of stress (85, 60 and 35% of field capacity) and five varieties of wheat (Orom, Zarea, Mihan, ZSZOBKAYKA, JS3l7G217,) Analysis of variance showed, Pr...

چکیده توان بالقوه تجاری سلولازها و کاربردهای گوناگون آن ها در بسیاری از صنایع انگیزه ای قوی برای تحقیق در این زمینه طی چند دهه گذشته بوده است. با توجه به کاربردهای فراوان این آنزیم در صنایع غذایی? در این پژوهش تصمیم به جداسازی ریزسازواره های تولید کننده سلولاز از خاک درختان انار، انگور، خرمالو و گردو حیاط دانشکده کشاورزی تربیت مدرس، گرفته شد. در این بین خاک درخت خرمالو به دلیل دارا بودن تعداد ...

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...

 Background and Objective: Aminopeptidases remove the amino acids from the N-terminal of proteins and peptides. Aminopeptidase N (CD13) and leucine aminopeptidase are involved in processing and presentation of pathogens to immune cells. Also, enzyme activity in some viral infection and tumors are high. In this study, the activity of CD13 in serum with high level of brucella antibody wa...

Background: Thymus species have significant amounts of phenolic and flavonoid compounds and demonstrate strong antioxidant activities. Paraoxonase1 act as antioxidant enzyme and protect the low-density lipoprotein against oxidation. In our study we aimed to evaluate the antioxidant capacity of Thymus Kotschyanus Hydroalcoholic extract and its effect on serum paraoxonase 1 activity in healthy an...
