AIM To study the antioxidant activity, UV absorption, concentration and stability of ascorbic acid (AA) in porcine and bovine aqueous humour (AH). METHODS Porcine and bovine AH was taken within 5 min after death and frozen at -70 degrees C. The characteristic UV absorption band of AA and the concentration of AA in AH was determined by UV spectrophotometry. The antioxidant activity of AA to se...
We investigated the properties of platelet-activating factor acetylhydrolase (PAF-AH) derived from Trichoderma harzianum. The enzyme, comprised of 572 amino acids, shares high homology with PAF-AH proteins from T. koningii and other microbial species. The optimum enzymatic activity of PAF-AH occurred at pH 6 in the absence of Ca2+ and it localized in the cytoplasm, and we observed the upregulat...
BACKGROUND Avoidable hospitalizations (AH) are hospital admissions for diseases and conditions that could have been prevented by appropriate ambulatory care. We examine regional variation of AH in Switzerland and the factors that determine AH. METHODS We used hospital service areas, and data from 2008-2010 hospital discharges in Switzerland to examine regional variation in AH. Age and sex sta...
هدف درمان اندودنتیک حذف میکروارگانیسم ها و محصولات جانبی آنها از کانال ریشه و همچنین ایجاد سیل مناسب جهت جلوگیری از عفونت مجدد این سیستم می باشد. سیلرهای mta fillapex و iroot sp دو سیلر جدید هستند که بر اساس ادعای سازندگان، ویژگی های بسیار مشابه با mta دارند. هدف از این مطالعه بررسی و مقایسه ی سیل اپیکال کانال های پر شده با سیلرهای iroot sp ، mta fillapex و ah-plus می باشد. 120 دندان پرمولر تک...
Background and purpose: The seeds of Astragalus hamosus L. are prescribed for many therapeutic purposes in Traditional Persian Medicine. The present study aimed to investigate the combined effects of metformin and ethanolic extract of Astragalus hamosus L. (AH) on glucose and reproductive parameters in diabetic male rats. Materials and methods: Ethanolic extract of AH was prepared using macera...
During a study of the capacity of Syrian hamster cells derived from various organs to transform in vitro after exposure to simian virus 40 (SV40), it was found that cells from lung and liver responded differently compared to those from certain other organs. The most significant difference was the apparent absence of the viral genome in lung and liver cultures that eventually underwent transform...
