HIV-1 is able to express multiple protein types and isoforms from a single 9 kb mRNA transcript. These proteins are also expressed at particular stages of viral development, and this is achieved through the control of alternative splicing and the export of these transcripts from the nucleus. The nuclear export is controlled by the HIV protein Rev being required to transport incompletely spliced...

The LPP gene is the preferred translocation partner of the HMGIC gene in a subclass of human benign mesenchymal tumors known as lipomas. Here we have characterized the LPP gene product that shares 41% of sequence identity with the focal adhesion protein zyxin. LPP localizes in focal adhesions as well as in cell-to-cell contacts, and it binds VASP, a protein implicated in the control of actin or...

Iran`s pharmaceutical products market as one of the major markets of the country has been faced with fluctuations over time. Suitable market selection is necessary for stability of pharmaceutical exports. Study of the global market structure of this product leads to policy makers in development, production, and trade of pharmaceuticals and finally increases country’s share of the world pharmace...

In metazoa, assembly of spliceosomal U snRNPs requires nuclear export of U snRNA precursors. Export depends upon the RNA cap structure, nuclear cap-binding complex (CBC), the export receptor CRM1/Xpo1, and RanGTP. These components are however insufficient to support U snRNA export. We identify PHAX (phosphorylated adaptor for RNA export) as the additional factor required for U snRNA export comp...

This paper discusses the practical issues that arise when securing the access to the World Wide Web (WWW). A brief overview of the different protocols that are proposed to secure the WWW is given and the current status of the U.S. export regulations is reviewed. An attack on SSL 2.0 is detailed which exploits some of the weaknesses in this protocol. The setup of a secure server with access cont...

Abstract:Non-oil exports are increased in the measures taken, to reduce Iran's dependence on oil revenues. Creating new business areas in different sectors and unused capacities are fac-tors that make it imperative to pay attention to the development of non-oil exports. Ex-port growth is the key to economic recovery for governments. Among non-oil exports, in many countries of the world th...

The relationship between initiating export stimuli and export performance is examined within the context of four specific types of export marketing strategies. The nature of the export stimulus is seen to be associated with performance for some types of strategy but not for all. Consequently, export marketing strategy acts as a moderator of the relationship between export stimuli and the perfor...
