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...

OBJECTIVE The purpose of this study was to evaluate the release of formaldehyde by some root canal filling materials. STUDY DESIGN Two older endodontic sealers, AH 26 and Endomethasone, and 2 recently available sealers, AH Plus and Top Seal, were analyzed. Infrared and electronic spectroscopy were used to determine formaldehyde content after set of the materials. RESULTS Analysis showed tha...
To evaluate the significance of the refractory period and conduction time of the AV node for reentrant tachycardias incorporating the AV node, the effective refractory period of the AV node (ERP) and AH interval (AH) during atrial pacing at various cycle lengths were measured in 12 anesthetized dogs after verapamil administration. ERP-AH tended to be constant in each dog at different cycle leng...
