The development of functional connections between the axons of retinal ganglion cells and the neurons of the dorsal lateral geniculate nucleus (LGNd) of fetal and neonatal cats was studied using an in vitro assay. Extracellular microelectrode recordings of single units were made from histologically identified sites in the LGNd of isolated diencephalon preparations between embryonic day 39 ( E39...
Glycoprotein (GP) VI is the major receptor responsible for platelet activation by collagen, but the collagen-binding surface of GPVI is unknown. To address this issue we expressed, from insect cells, the immunoglobulin (Ig)-like ectodomains (residues 1-185) of human and murine GPVI, called hD1D2 and mD1D2, respectively. Both proteins bound specifically to collagen-related peptide (CRP), a GPVI-...
در این مقاله رهیافت پولی به نرخ ارز در کشورهای منتخب حاشیه ی خلیج فارس در مقایسه با کشورهای سازمان همکاری اقتصادی و توسعه (OECD) مورد بررسی قرار گرفته است. برای این منظور از تکنیک همانباشتگی تابلویی طی دوره ی زمانی 2005-1989 استفاده شده است. نتایج به دست آمده نشان داد که رهیافت پولی به نرخ ارز در هر دو گروه از کشورها برقرار بوده است، ولی با توجه به ساختارهای اقتصادی متفاوت آنها، نسبت اث...
این مقاله، فرضیة اساسی انتظارات عقلایی مبنی بر خنثی بودن سیاست پولی یا عدم تأثیر این سیاست بر متغیرهای حقیقی تولید و اشتغال را در اقتصاد ایران طی سالهای 82- 1345، مورد آزمون قرار داده است. نتایج حاصل از تخمین معادلة تولید، اثرگذاری جزء پیشبینی نشدة حجم پول بر متغیر تولید را در سطح ازمون 5 درصد، رد می کنند، لذا نتایج بهدست آمده، مؤید این نکتهاند که سیاستهای پولی پیشبینی شده و منظم در طول د...
Epidemics and outbreaks caused by infections of several subgenotypes of EV71 and other serotypes of coxsackie A viruses have raised serious public health concerns in the Asia-Pacific region. These concerns highlight the urgent need to develop a scalable manufacturing platform for producing an effective and sufficient quantity of vaccines against deadly enteroviruses. In this report, we present ...
BACKGROUND N-ethyl-N-nitrosourea (ENU)-induced mutagenesis is a powerful tool for the study of gene function and the generation of human disease models. A large number of mouse mutants obtained by ENU-induced mutagenesis with a variety of phenotypes have been recovered. However, after genetic confirmation testing, only approximately 50% of the abnormal phenotypes were found to be heritable. M...
The large balance sheet of many central banks has raised concerns that they could suffer significant losses if interest rates rose, and might need a capital injection from the fiscal authority. This paper constructs a simple deterministic general equilibrium model, calibrated to US data, to study the the impact of alternative interest rates scenarios on the central bank’s balance sheet. We show...
This paper presents new estimates of scale and product mix economies for U.S. commercial banks. We compare estimates derived from fitting a translog function to bank costs with estimates derived from nonparametric methods. We refine measures of scale and product mix economies introduced by Berger et al. (J. Monet. Econ. 20 (1987) 501) to accommodate nonparametric estimation, and estimate confid...
This paper presents conditions for a resolution of the Grossman-Stiglitz paradox of informationally ef cient markets. We display a market with asymmetric information where a privately revealing equilibrium obtains in a competitive framework and where incentives to acquire information are preserved as long as the correlation in traders’ valuations is not too large. The equilibrium is ef cient, a...
