In eukaryotic cells, the nuclear membrane creates a barrier between the nucleus and the cytoplasm. Whereas RNA synthesis occurs in the nucleus, they mostly function in the cytoplasm; thus export of RNA molecules from the nucleus to the cytoplasm is indispensable for normal function of the cells. The molecular mechanisms involved in each kind of cellular RNA export is gradually understood. The f...

raisin is the second major export item in iranian agricultural section after pistachio. in this study, effects of exchange rate fluctuations were investigated on quantity and price of exported raisin. therefore, data of 1970 to 2008 were reviewed by time series analysis and estimated by auto-regressive distributed lag model (ardl). results show the absence of a long-term relationship between ex...

Since the end of the Cold War the world has witnessed significant political and economic developments with far-reaching consequences for global order. For instance, the democratisation processes and outcomes in some countries in Eastern Europe, Latin America and Africa have benefited from the triumph of globalisation. Also, the new neoliberal global order under the influence of the United State...

There is remarkable redundancy between the Cyclin-Cdk complexes that comprise the cell cycle machinery. None of the mammalian A-, D-, or E-type cyclins are required in development until implantation, and only Cdk1 is essential for early cell divisions. Cyclin B1 is essential for development, but whether it is required for cell division is contentious. Here, we used a novel imaging approach to a...

To investigate the seasonal and interannual variations in biological productivity in the South China Sea (SCS), a Pacific basin-wide physical–biogeochemical model has been developed and used to estimate the biological productivity and export flux in the SCS. The Pacific circulation model, based on the Regional Ocean Model Systems (ROMS), is forced with daily air–sea fluxes derived from the NCEP...

Several factors contribute to nuclear mRNA export in Saccharomyces cerevisiae, including Mex67p, Mtr2p, Gle1p, Nup159p, Dbp5p, and Rip1p. Strains carrying mutations in these factors show rapid and dramatic nuclear accumulation of poly(A)(+) RNA. We have characterized two heat shock mRNAs, SSA4 and HSP104, in these mutant backgrounds; each transcript concentrates in a single intranuclear focus. ...

the main purpose of this paper is to investigate the impact of trade openness on the employment and the real wage for the iranian food and beverage industries over the year 2007. for this purpose in this study, the ratio of export to production value has been considered as a proxy for trade openness and the main model has been estimated using a dynamic panel data (dpd) approach. the main findin...

The relative value of currencies varies considerably over time. These fluctuations bring uncertainty to international traders. As a result, the volatility in exchange rate movements may influence the volume and the price of traded commodities. The volatility of exchange rates was measured by the variance of residuals in a GARCH(1,1) model of the exchange rate. We estimated the effect of this ex...
