abstract export of nonoil goods in economic activities is so important and its effect on economic and comparative growth is undeniable. so, emphasize on agricultural sector and development of export in this sector prepares good conditions, for iran, to be present at international markets relying its advantages. the study tries to recognize necessary policies to enhance agricultural export poten...

The rapid world economic growth have stimulated the businesses towards involvement in international marketplaces due to their low business risks, low commitment of resources and high flexibility. However, the evidence indicates barriers to export are thought to vary across different stages of internationalization. Therefore, this empirical study was carried out to explore export barriers of agr...

Rodent cells are notable for their inability to support normal assembly of HIV particles. In this report, we address possible causes for this defect by considering the hypothesis that mRNA-associated events occurring in the nucleus can regulate the activity of their encoded proteins in the cytoplasm. We show that altering the RNA nuclear export element used by HIV gag-pol mRNA from the Rev resp...

The efficient export of the Escherichia coli maltose-binding protein (MBP) is known to be SecB dependent, whereas ribose-binding protein (RBP) export is SecB independent. When the MBP and RBP signal peptides were exchanged precisely at the signal peptidase processing sites, the resultant RBP-MBP and MBP-RBP hybrid proteins both were efficiently exported in SecB+ cells. However, only MBP-RBP was...

Transduction of developmental and environmental cues into the nucleus to induce transcription and the export of RNAs to the cytoplasm through the nuclear pore complex (NPC) play pivotal roles in regulation of gene expression. The process of bulk export of mRNAs from nucleus to cytoplasm is highly conserved across eukaryotes. Assembly of export-competent mRNA ribonucleoprotein (mRNP) is coupled ...
