در مطالعه های اقتصادی تاکید زیادی بر نقش دولت در تنظیم ادوار تجاری به ویژه در کشورهای در حال توسعه شده است که در آن ها سرمایه گذاری دولتی در کنار سایر ابزارهای دولت برای تحریک رشد اقتصادی مورد استفاده قرار می گیرد. این که مخارج دولت به چه میزان تولید را تحت تأثیر قرار می دهد به نحوه تأمین مالی آن نیز بستگی دارد. نفت در اقتصاد ایران نقش قابل توجهی به ویژه در بودجه کشور ایفا می کند به طوری که بیش...
هدف این مقاله، بررسی اعتبار قانون واگنر و دیدگاه کینزی در خصوص ارتباط میان تولید ناخالص داخلی غیر نفتی و اندازه بخش عمومی طی دوره 8۶-۱۳4۶ برای اقتصاد ایران میباشد. به این منظور، روش¬های تجزیه و تحلیل سری¬های زمانی، مشتمل بر آزمون¬های ریشه واحد، آزمون های هم¬انباشتگی و آزمون علیت هسیائو به کار گرفته شدهاند. یافته¬های تحقیق نشان میدهند که قانون واگنر در هر دو افق زمانی کوتاه مدت و بلند مدت تأ...
New X-ray observations of the sparse NGC 3258 group of galaxies made by the ASCA satellite with good spectral and spatial resolution has revealed that this group has a gravitational potential deep enough to prohibit significant mass removal from the system. The baryonic fraction within 240h 50 kpc is found to be 0.065 −0.020 for h50 = 1, where h50 ≡ H0/50 km s Mpc, in good agreement with the un...
A hypothesis was tested that the in ovo injection of biological buffers may reinforce the buffering capacity of albumen, thereby withstanding the increase in albumen pH during storage and improving hatchability and chick quality in long-term stored eggs. Hatching eggs (n = 2,420) were randomly assigned to 11 treatment groups (4 replicates of 55 eggs each) and injected (d 1) with distilled water...
The E2A gene encodes two alternatively spliced products, E12 and E47. The two proteins differ in their basic helix-loop-helix motifs (bHLH), responsible for DNA binding and dimerization. Although both E12 and E47 can bind to DNA as heterodimers with tissue-specific bHLH proteins, E12 binds to DNA poorly as homodimers. An inhibitory domain in E12 has previously been found to prevent E12 homodime...
Phenotypic transformation of mesangial cells (MCs) is implicated in the development of glomerular disease; however, the mechanisms underlying their altered genetic program is still unclear. α-smooth muscle actin (α-SMA) is known to be a crucial marker for phenotypic transformation of MCs. Recently, E-boxes and the class I basic helix-loop-helix proteins, such as E12 have been shown to regulateα...
The legume pod borer, Maruca vitrata (Lepidoptera: Crambidae; syn. M. testulalis), is a serious pantropical insect pest of grain legumes. Comparative studies of M. vitrata female sex pheromone components in two different geographic populations in China, Wuhan and Huazhou, confirmed that (E,E)-10,12-hexadecadienal (E10,E12-16:Ald) and (E)-10-hexadecenal (E10-16:Ald) were present in variable rati...
The E2A gene products, E12 and E47, are critical regulators of B cell development. However, it remains elusive whether E12 and E47 have overlapping and/or distinct functions during B lymphopoiesis. We have generated mice deficient for either E12 or E47 and examined their roles in B cell maturation. We show that E47 is essential for developmental progression at the prepro-B cell stage, whereas E...
The HT29MTXE12 (E12) cell line harbors an adherent mucus layer, providing a novel technique to model mucosal infection in vitro. In this study, we have characterized the interaction of Campylobacter jejuni with the E12 cell line and exploited its unique mucus layer to examine the potential efficacy of probiotic treatment to attenuate C. jejuni virulence properties. C. jejuni 81-176 colonized an...
