Signal-dependent nuclear protein export was studied in perforated nuclei and isolated nuclear envelopes of Xenopus oocytes by optical single transporter recording. Manually isolated and purified oocyte nuclei were attached to isoporous filters and made permeable for macromolecules by perforation. Export of a recombinant protein (GG-NES) containing the nuclear export signal (NES) of the protein ...

the main purpose of this paper is to investigate the performance of nigerian insurance companies using data envelopment analysis (dea). because of the unavailability of the required data, the study is limited to ten nigerian insurance companies for the period of five years from 2008 to 2012. the input employed were commission expenses and management expenses, while premium and investment income...

export and the readiness to export constitute the first step of international marketing, which are affected by both internal and external factors of firms. one of the most important internal  factors is the presence of skilled personnel. the purpose of this study was to define the relationship between staff qualification and encouragment with the readiness level of iranian pharmacuetical firms ...

This paper investigates the relationships between firm, industry and market-related variables, strategy, strategy implementation and performance for Philippines exporters. The model follows Cavusgil and Zou (1994) with the addition of strategy implementation as a mediating variable between strategy and performance. We conclude that strategy implementation influences performance, both directly, ...

The hTREX complex mediates cellular bulk mRNA nuclear export by recruiting the nuclear export factor, TAP, via a direct interaction with the export adaptor, Aly. Intriguingly however, depletion of Aly only leads to a modest reduction in cellular mRNA nuclear export, suggesting the existence of additional mRNA nuclear export adaptor proteins. In order to efficiently export Kaposi's sarcoma-assoc...

The production of ribosomes constitutes a major biosynthetic task for cells. Eukaryotic small and large ribosomal subunits are assembled in the nucleolus and independently exported to the cytoplasm. Most nuclear export pathways require RanGTP-binding export receptors. We analyzed the role of CRM1, the export receptor for leucine-rich nuclear export signals (NES), in the biogenesis of ribosomal ...

Protons are utilized for various biological activities such as energy transduction and cell signaling. For construction of the bacterial flagellum, a type III export apparatus utilizes ATP and proton motive force to drive flagellar protein export, but the energy transduction mechanism remains unclear. Here, we have developed a high-resolution pH imaging system to measure local pH differences wi...

This paper tries to define the concept of Export Finance and establish if the Export Financing is cost-effective way to raise capital and how is it organized in the Russian Federation. In order to do so, several methods have been used: the related literature has been studied, numerical analysis of economic-efficience of export financing has been prepared based on the real example and three inte...

introduction social security policies, and particularly the social insurance strategies, are awing important publicly supportive mechanisms to meet the communities’ social vulnerabilities. social insurance of rural people in iran has practically been conducted in recent years through the rural and nomadic social insurance fund. the widespread use of social insurance depends on the extent of its...
