هدف اساسی رساله بررسی این مسئله بود که ابزارها و شیوه های مشارکتی حمایتی که عمده ترین شیوه مشارکتی در دوره جنگ و قبل از آن بوده است . آیا توانسته اند مشارکت فعال و حتی حمایتی نیروهای اجتماعی را فراهم کنند. برای پاسخ به این سئوال ابتدا با توجه به مبانی نظری تحقیق، ابزارهای و شیوه های مشارکتی در جمهوری اسلامی را در دو گونه ابزارهای مستقیم و ابزارهای غیرمستقیم (سازمانی) مورد مطالعه قرار دادیم. انت...
A complicating factor in the translational pharmacology of sphingosine 1-phosphate agonists is that they exert their pharmacological effect through their respective phosphate metabolites, which are formed by the enzyme sphingosine kinase (S1PHK). In this investigation, we present a semimechanistic pharmacokinetic model for the interconversion of S1PHK substrates and their respective phosphates ...
In the 2012 Food and Drug Administration (FDA) draft guidance on drug-drug interactions (DDIs), a new molecular entity that inhibits Pglycoprotein (P-gp) may need a clinical DDI study with a P-gp substrate such as digoxin when themaximum concentration of inhibitor at steady state divided by IC50 ([I1]/IC50) is ‡0.1 or concentration of inhibitor based on highest approved dose dissolved in 250 ml...
The structure of a protein depends critically on the complex interactions among its amino acid residues. It has long been hypothesized that interacting residues might tend to coevolve, but it is not known whether such coevolution is a general phenomenon across the proteome. Here, we describe a novel methodology called phylogeny-aided structural analysis, which uncovers robust signals of interac...
Tryptophan metabolites have been linked in observational studies with type 2 diabetes, cognitive disorders, inflammation and immune system regulation. A rate-limiting enzyme in tryptophan conversion is arylformamidase (Afmid), and a double knockout of this gene and thymidine kinase (Tk) has been reported to cause renal failure and abnormal immune system regulation. In order to further investiga...
Bone morphogenetic protein (BMP) signaling plays many roles in skull morphogenesis. We have previously reported that enhanced BMP signaling through the BMP type IA receptor (BMPR1A) in cranial neural crest cells causes craniosynostosis during postnatal development. Additionally, we observed that 55% of Bmpr1a mutant mice show neonatal lethality characterized by a distended gastrointestinal trac...
