BACKGROUND Fluorescent reporter proteins have revolutionized our understanding of cellular bioprocesses by enabling live cell imaging with exquisite spatio-temporal resolution. Existing fluorescent proteins are predominantly based on the green fluorescent protein (GFP) and related analogs. However, GFP-family proteins strictly require molecular oxygen for maturation of fluorescence, which precl...
This study investigates the performance and risk of currency hedge funds from 1999 to 2009. Our results show that a substantial number of hedge funds generate returns that exceed foreign exchange risk premia obtained through carry trades. Small funds perform better than large funds and the best alpha-generating funds exhibit a performance that persists over a one-year horizon. This performance ...
Sufficient solubility of the active protein in aqueous solution is a prerequisite for crystallization and other structural studies of proteins. In this study, we have developed a simple and effective in vivo screening system to select for functionally active proteins with increased solubility by using Plasmodium falciparum dihydrofolate reductase (pfDHFR), a well-known malarial drug target, as ...
This paper studies the interaction between monetary and macro-prudential policies in a simple model with both nominal and financial frictions. The nominal friction gives rise to a conventional monetary policy objective emphasized in the New Keynesian literature. The financial friction, in the form of an occasionally binding collateral constraint, gives rise to a financial stability objective. ...

در ابتدا دی اسید (35) حاوی واحد بای سیکلو و قطعات ایمیدی با موفقیت تهیه شد و سپس توسط دی آمینهای مختلف در حضور tpp/nmp/py پلی(آمید- ایمید)های (a-f37) تهیه و خصوصیات آنها مورد بررسی قرار گرفت. در ادامه کار، قسمت اول تهیه و خصوصیات دو دسته از پلیمرهای سنتزی بررسی شده است. دسته اول که شامل پلی(آمید- ایمید)های مقاوم حرارتی و ضد آتش می باشند، از واکنشهای تراکمی مستقیم بین انواع دی اسید ها شامل -n,n...
T he main purpose of this article is to analyze exchange rate behavior based on monetary fundamentals in the context of Iranian economy over the period 1990:2 to 2014:3. To do so, two monetary exchange rate models is investigated, the first by regarding interest rate differential as a monetary variable, and the second one regardless of interest rate differential as a monetary variabl...
امروزه به دلیل بروز مشکلات ناشی از استفاده ی بی رویه سموم شیمیایی در مزارع کشاورزی، گرایش زیادی به استفاده از مواد بیولوژیکی از جمله متابولیت های ثانویه گیاهی جهت کنترل بیماری ها و آفات گیاهی ایجاد شده است. مطالعه ی حاضر با هدف بررسی اثرات ضدقارچی برخی اسانس های گیاهی و قارچکش های شیمیایی به منظور کنترل بیماری پژمردگی فوزاریومی در چند گیاه مختلف انجام گردید. بدین منظور نمونه های نخود ایرانی از ...
defined according to the Prostate Imaging – Reporting and Data System (PI-RADS) version 2 published in 2015.9 There were five PI-RADS assessment categories (1–5) correlating with probability of having significant cancer. The software Profuse (Eigen, Grass Valley, CA, USA) was used to outline the contour of the prostate and any PI-RADS 2–5 lesions. The Digital Imaging and Communication in Medici...
