3 - متیل - 5 - فنیل - 4h - پیرازولنین - 4 - اون n و n* - دی اکسید (12b) تقش آغازگر در پلیمریزاسیون متیل متا آکریلات دارد پلیمریزاسیون ، در دماهای متغیر ، در حضور این آغازگر انجام شد و ساختار آمرف آن را از طریق بررسی ir h nmr، ترموگرام dscو کروماتوگرام gpc می توان ثابت نمود.پلیمریزاسیون متیل متا آکریلات در حضور نیتروژن (12b)نیز در غلظت های متغیر انجام و نشان داده ...
Reaction of tryptamine 1 with dimethyl -3-methoxyallylidenemalonate 2 afforded N?-[4,4-bis (methoxycarbonyl)-1,3-butadienyl] tryptamine 3 which in combination with acetylchloride and pyridine in dichloromethane gave N?, N?-[acetyl]-[(4,4-dinethoxycarbonyl) 1,3butadienyl] tryptamine 4. Treatment of 3 with sodium hydroxide afforded 2H[N-(3-indolyl) ethyl] 2-oxo-3-methoxycarbonyl-1-pyridine 5. Cy...
Sorghum (Sorghum bicolor (L.) Moench) is one of the major crops for grain and fodder, widely grown in India under rain fed conditions. Rabi sorghum is grown in an area of 5.5 million hectares mainly in the states of Maharashtra, Karnataka and Andhra Pradesh with average productivity of 854 kg/ha. Despite low productivity, Rabi sorghum continues to be an important component of dry land economy i...
The causative agent of Johne's disease is Mycobacterium avium subsp. paratuberculosis. This is a chronic, debilitating gastrointestinal disorder that affects ruminants and is responsible for significant economic loss. The specimen processing method that combines C(18)-carboxypropylbetaine (CB-18) treatment and lytic enzyme decontamination has been shown to improve the diagnosis of mycobacterios...
C-Glycosyl-(S)- and (R)-alanines 12a and 12b were synthesized from the known beta-C-glycoside 1. The nitrogen function was introduced by aza-Claisen rearrangement of the allylic thiocyanate 7, derived from the corresponding alcohol 6. The absolute configuration of the newly created chiral carbon center (C-3) was assigned by X-ray diffraction analysis of the intermediate 3(S)-isothiocyanato-D-gl...
INTRODUCTION Both monocyte chemoattractant protein-1 (MCP-1), also designated officially as chemokine (C-C motif) ligand 2 (CCL2), and interleukin-12 p40 (IL-12 p40) molecules, encoded by polymorphic genes, are central components of the immune response to infection by Mycobacterium tuberculosis (Mtb). Their genetic diversity has previously been associated with the outcome of tuberculosis (TB) i...
Background. Systemic lupus erythematosus (SLE) is a complex immune disease. The genetic variation in the IL-12b gene was found to associate with SLE in Caucasian population. In this study, we examined this association in Chinese Han population by a recently developed method, unlabeled probe-based high resolution melting analysis. Methods. A total of 297 SLE patients and 351 controls were recrui...
دو آزمایش طراحی شد تا اثر سطوح مختلف کبالت جیره را بر عملکرد، غلظت ویتامین12B پلاسما و سنتز پروتئین میکروبی در بره‌های نر مهربان مورد بررسی قرار دهد. 28 رأس بره در آزمایش اول بطور تصادفی به چهارگروه تقسیم شدند و با جیره پایه حاوی 088/0 میلی‌گرم کبالت در کیلوگرم ماده خشک تغذیه شدند و مکمل کبالت را با سطوح صفر (شاهد)، 25/0، 5/0 یا 1 میلی‌گرم کبالت در کیلوگرم ماده خشک به مدت 70 روز دریافت کردند. ب...
We present Warm Spitzer/IRAC secondary eclipse time series photometry of three short-period transiting exoplanets, HAT-P-3b, HAT-P-4b and HAT-P-12b, in both the available 3.6 and 4.5μm bands. HAT-P-3b and HAT-P-4b are Jupiter-mass, objects orbiting an early K and an early G dwarf stars, respectively. For HAT-P-3b we find eclipse depths of 0.112% −0.030% (3.6μm) and 0.094% +0.016% −0.009% (4.5μm...
