azidahak (zahhak) has always been a strange myth among the other mythological characters in pre-islamic literature. is it possible to figure out a specific historical period for his life? or as avesta's image shows, we should consider him as a semi-human, semi-monster notion with three ugly heads on his shoulder? this article tries to put this figure on the spotlight and illuminate his rea...
سابقه و هدف: با وجود مقدار نسبتاً زیادی از پتاسیم در خاک، مشکل دسترسی به منابع پتاسیمی، مهمترین عامل بروز کمبود پتاسیم در گیاهان میباشد. بنابراین تجزیه کانیهای خاک توسط میکروارگانیسمها قابل تأمل بوده و در این بین کاربرد باکتریهای آزادکننده پتاسیم میتواند از اهمیت بیشتری برخوردار باشد. بر این اساس این آزمایش با هدف بررسی تأثیر جدایههای مختلف باکتریایی در تأمین پتاسیم گیاه ذرت انجام شد. م...
Azemiopsin (Az), a linear peptide from the Azemiops feae viper venom, contains no disulfide bonds, is a high-affinity and selective inhibitor of nicotinic acetylcholine receptor (nAChR) of muscle type and may be considered as potentially applicable nondepolarizing muscle relaxant. In this study, we investigated its preclinical profile in regard to in vitro and in vivo efficacy, acute and chroni...
Let G be a connected reductive algebraic group with Lie algebra g defined over an algebraically closed field, k, with char k = 0. Fix a parabolic subgroup of G with Levi decomposition P = LU where U is the unipotent radical of P . Let u = Lie(U) and let z denote the center of Lie(L). Let T be a maximal torus in L with Lie algebra t. Then the root system of (g, t) is a subset of t∗ and by restri...
We injected acetazolamide (AZ; 5 x 10(-6) M, 1 nl) into the region of the ventral respiratory group (VRG) of anesthetized paralyzed ventilated rats. Control injections (mock cerebrospinal fluid, n = 6, or the inactive AZ analogue 2-acetylamino-1,3, 4-thiadiazole-5-sulfon-t-butylamide, n = 6) did not increase the integrated phrenic neurogram [phrenic nerve amplitude (PNA)]. The AZ injections pro...
Coarse grid correction is a key ingredient in order to have scalable domain decomposition methods. In this work we construct the coarse grid space using the low frequency modes of the subdomain DtN maps, and apply the obtained two-level preconditioners to the extended or the original linear system arising from an overlapping domain decomposition. Our method is suitable for parallel implementati...
OBJECTIVE The aim of this study was to investigate the possible influence of single-dose 2.0-g azithromycin (AZ-ER) on anticoagulation in patients taking warfarin. STUDY DESIGN Eighteen consecutive patients receiving long-term stable warfarin therapy were enrolled in this study. AZ-ER was administered 1 hour prior to tooth extraction. The international normalized ratio (INR) value was measure...
