این پژوهش به منظور تعیین ترکیبات شیمیایی و ارزش غذایی سیلوی برگ خرما با افزودن اوره، خرمای غیرخوراکی و زئولیت به روش in vitro و in situ انجام شد. بدین منظور برگ خرما جمع¬آوری و جهت سیلو نمودن به قطعات 4-2 سانتی¬متری خرد گردید. سپس با استفاده از اوره (5 درصد)، خرمای غیرخوراکی (15 درصد) و زئولیت (4 گرم در کیلوگرم ماده خشک) قبل از سیلو مخلوط و درون سطل-های 5 کیلویی پلاستیکی در دمای آزمایشگاه سیلو ...
یک روش بیولوژیکی سازگار با محیط زیست برای سنتز نانوذرات نقره توسط سویه ی اینتروباکتر ckcr-8 در این تحقیق، توصیف شده است. باکتری از معادن کروم جداسازی شد، و مشخص گردید که این باکتری دارای توانایی کاهش نقره (+) به نقره (0)، تحت شرایط in vitro می باشد. رنگ حدواسط از زرد به قهوه ای تغییر پیدا کرد و اینگونه نشانه های اولیه حضور نانوذرات برای ما به اثبات رسید. درادامه، برای تحقیق بیشتر در مورد نانوذر...
BACKGROUND AND OBJECTIVE The objective of this study is to determine the status of acrosome intactness in different infertile conditions among men who have attended the Mediwave Fertility Research Center, Mysore, South India. MATERIALS AND METHODS A total of 70 infertile and 20 control subjects were employed in the study. Infertile subjects were classified into different conditions according ...
A series of N-substituted-quinolinone-3-aminoamides and their hybrids containing the alpha-lipoic acid functionality were designed and synthesized as potential bifunctional agents combining antioxidant and anti-inflammatory activity. The new compounds were evaluated for their antioxidant activity and for their ability to inhibit in vitro lipoxygenase as well as for their anti-inflammatory activ...
Background and purpose: Diazinon is an organophosphate insecticide that binds to the acetylcholinesterase enzyme after metabolization causing its inactivation. Galic acid is a polyphenolic compound with nucleophilic properties. The aim of this study was to investigate the effects of gallic acid on reactivation of acetylcholine and butyrylcholinesterase inhibited by diazinon in mice and human se...
Some medicinal plants are a potential source of new drugs, in order to improve the treatment of Chagas disease whose treatment is still a challenge. In this study, the in vitro anti-epimastigote activity of certain fractions of Achillea biebersteinii, A. millefolium, Satureja mutica and S. macrantha was evaluated. Diethyl ether fractions of Achillea species and acetone fractions of Satureja spe...
The aim of this study was to assay the antibacterial activity of Scenedesmus obtusus on some pathogenic bacteria. Microalgae S. obtusus were obtained from Algae Bank of Iran, and the methanol, ethyl acetate, chloroform and n-hexane extract of the microalgae were prepared using the maceration method. Bacterial strains were cultured in a solid culture medium, and antibacterial activity of the the...
BACKGROUND Thalassemia, which may be due to point mutations, translocations, and deletions involving the α or βglobin gene, is the most prevalent single gene disorder in Iran.This study aims to calculate the α/β ratio in normal cases, α- and β-thalassemia carriers by RT-PCR, real-time PCR, and in vitro globin chain synthesis (GCS) in order to establish the most accurate technique to distinguish...
Lycopene nanoemulsions were prepared to protect the antioxidant activity and improve the bioaccessibility of lycopene-enriched tomato extract (containing 6% of lycopene) by an emulsification-evaporation method. Lycopene nanoemulsions, with droplet sizes between 100 and 200 nm, exhibited higher anti-radical efficiency and antioxidant activity, than did those smaller than 100 nm. Strong protectab...
