Using mass spectrometry we have identified proteins which co-immunoprecipitate with paxillin, an adaptor protein implicated in the integrin-mediated signaling pathways of cell motility. A major component of paxillin immunoprecipitates was poly(A)-binding protein 1, a 70-kDa mRNA-binding protein. Poly(A)-binding protein 1 associated with both the alpha and beta isoforms of paxillin, and this was unaffected by RNase treatment consistent with a protein-protein interaction. The NH(2)-terminal region of paxillin (residues 54-313) associated directly with poly(A)-binding protein 1 in cell lysates, and with His-poly(A)-binding protein 1 immobilized in microtiter wells. Binding was specific, saturable and of high affinity (K(d) of approximately 10 nm). Cell fractionation studies showed that at steady state, the bulk of paxillin and poly(A)-binding protein 1 was present in the "dense" polyribosome-associated endoplasmic reticulum. However, inhibition of nuclear export with leptomycin B caused paxillin and poly(A)-binding protein 1 to accumulate in the nucleus, indicating that they shuttle between the nuclear and cytoplasmic compartments. When cells migrate, poly(A)-binding protein 1 colocalized with paxillin-beta at the tips of lamellipodia. Our results suggest a new mechanism whereby a paxillin x poly(A)-binding protein 1 complex facilitates transport of mRNA from the nucleus to sites of protein synthesis at the endoplasmic reticulum and the leading lamella during cell migration.

Effect of the unfolded protein response on ER protein export: a potential new mechanism to relieve ER stress.

The unfolded protein response (UPR) is an adaptive cellular response that aims to relieve endoplasmic reticulum (ER) stress via several mechanisms, including inhibition of protein synthesis and enhancement of protein folding and degradation. There is a controversy over the effect of the UPR on ER protein export. While some investigators suggested that ER export is inhibited during ER stress, others suggested the opposite. In this article, their conflicting studies are analyzed and compared in attempt to solve this controversy. The UPR appears indeed to enhance ER export, possibly via multiple mechanisms. However, another factor, which is the integrity of the folding machinery/environment inside ER, determines whether ER export will appear increased or decreased during experimentation. Also, different methods of stress induction appear to have different effects on ER export. Thus, improvement of ER export may represent a new mechanism by which the UPR alleviates ER stress. This may help researchers to understand how the UPR works inside cells and how to manipulate it to alter cell fate during stress, either to promote cell survival or death. This may open up new approaches for the treatment of ER stress-related diseases.

Full Text Available Background The endoplasmic reticulum plays an important role in many cellular processes, which includes protein synthesis, folding and post-translational processing of newly synthesized proteins. It is also the site for quality control of misfolded proteins and entry point of extracellular proteins to the secretory pathway. Hence at any given point of time, endoplasmic reticulum contains two different cohorts of proteins, (i proteins involved in endoplasmic reticulum-specific function, which reside in the lumen of the endoplasmic reticulum, called as endoplasmic reticulum resident proteins and (ii proteins which are in process of moving to the extracellular space. Thus, endoplasmic reticulum resident proteins must somehow be distinguished from newly synthesized secretory proteins, which pass through the endoplasmic reticulum on their way out of the cell. Approximately only 50% of the proteins used in this study as training data had endoplasmic reticulum retention signal, which shows that these signals are not essentially present in all endoplasmic reticulum resident proteins. This also strongly indicates the role of additional factors in retention of endoplasmic reticulum-specific proteins inside the endoplasmic reticulum. Methods This is a support vector machine based method, where we had used different forms of protein features as inputs for support vector machine to develop the prediction models. During training leave-one-out approach of cross-validation was used. Maximum performance was obtained with a combination of amino acid compositions of different part of proteins. Results In this study, we have reported a novel support vector machine based method for predicting endoplasmic reticulum resident proteins, named as ERPred. During training we achieved a maximum accuracy of 81.42% with leave-one-out approach of cross-validation. When evaluated on independent dataset, ERPred did prediction with sensitivity of 72.31% and specificity of 83

Oxysterol-binding protein (OSBP) exchanges cholesterol and phosphatidylinositol 4-phosphate (PI-4P) at contact sites between the endoplasmic reticulum (ER) and the trans-Golgi/trans-Golgi network. 25-Hydroxycholesterol (25OH) competitively inhibits this exchange reaction in vitro and causes the constitutive localization of OSBP at the ER/Golgi interface and PI-4P-dependent recruitment of ceramide transfer protein (CERT) for sphingomyelin synthesis. We used PI-4P probes and mass analysis to determine how OSBP controls the availability of PI-4P for this metabolic pathway. Treatment of fibroblasts or Chinese hamster ovary (CHO) cells with 25OH caused a 50-70% reduction in Golgi-associated immunoreactive PI-4P that correlated with Golgi localization of OSBP. In contrast, 25OH caused an OSBP-dependent enrichment in Golgi PI-4P that was detected with a pleckstrin homology domain probe. The cellular mass of phosphatidylinositol monophosphates and Golgi PI-4P measured with an unbiased PI-4P probe (P4M) was unaffected by 25OH and OSBP silencing, indicating that OSBP shifts the distribution of PI-4P upon localization to ER-Golgi contact sites. The PI-4P and sterol binding activities of OSBP were both required for 25OH activation of sphingomyelin synthesis, suggesting that 25OH must be exchanged for PI-4P to be concentrated at contact sites. We propose a model wherein 25OH activation of OSBP promotes the binding and retention of PI-4P at ER-Golgi contact sites. This pool of PI-4P specifically recruits pleckstrin homology domain-containing proteins involved in lipid transfer and metabolism, such as CERT. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

The export receptor Crm1 forms a dimer to promote nuclear export of HIV RNA.

2014-12-08

The HIV Rev protein routes viral RNAs containing the Rev Response Element (RRE) through the Crm1 nuclear export pathway to the cytoplasm where viral proteins are expressed and genomic RNA is delivered to assembling virions. The RRE assembles a Rev oligomer that displays nuclear export sequences (NESs) for recognition by the Crm1-Ran(GTP) nuclear receptor complex. Here we provide the first view of an assembled HIV-host nuclear export complex using single-particle electron microscopy. Unexpectedly, Crm1 forms a dimer with an extensive interface that enhances association with Rev-RRE and poises NES binding sites to interact with a Rev oligomer. The interface between Crm1 monomers explains differences between Crm1 orthologs that alter nuclear export and determine cellular tropism for viral replication. The arrangement of the export complex identifies a novel binding surface to possibly target an HIV inhibitor and may point to a broader role for Crm1 dimerization in regulating host gene expression.

The HIV-1 Rev protein mediates export of unspliced and singly spliced viral transcripts by binding to the Rev response element (RRE) and recruiting the cellular export factor CRM1. Here, we investigated the recruitment of Rev to the transcription sites of HIV-1 reporters that splice either post......- or cotranscriptionally. In both cases, we observed that Rev localized to the transcription sites of the reporters and recruited CRM1. Rev and CRM1 remained at the reporter transcription sites when cells were treated with the splicing inhibitor Spliceostatin A (SSA), showing that the proteins associate with RNA prior...... to or during early spliceosome assembly. Fluorescence recovery after photobleaching (FRAP) revealed that Rev and CRM1 have similar kinetics as the HIV-1 RNA, indicating that Rev, CRM1, and RRE-containing RNAs are released from the site of transcription in one single export complex. These results suggest...

Endoplasmic reticulum stress in lung disease

Stefan J. Marciniak

2017-06-01

Full Text Available Exposure to inhaled pollutants, including fine particulates and cigarette smoke is a major cause of lung disease in Europe. While it is established that inhaled pollutants have devastating effects on the genome, it is now recognised that additional effects on protein folding also drive the development of lung disease. Protein misfolding in the endoplasmic reticulum affects the pathogenesis of many diseases, ranging from pulmonary fibrosis to cancer. It is therefore important to understand how cells respond to endoplasmic reticulum stress and how this affects pulmonary tissues in disease. These insights may offer opportunities to manipulate such endoplasmic reticulum stress pathways and thereby cure lung disease.

East Asia is the major atmospheric mercury (Hg) source region in the world due to the excessive coal combustion, industrial emission, and biomass burning in this area. Nonetheless, studies concerning the export of atmospheric Hg from East Asia are still limited. Accordingly, atmospheric Hg has been measured at various sites in Taiwan to study its temporal and spatial distribution, and the significance of long-range transport from the East Asian continent as well. Here we report the data collected in Fu-guei-jiao (121.97°E, 25.47°N, ~30 m a.s.l.), Mt. Bamboo (121.54°E, 25.19°N, 1025 m a.s.l.), and Lulin Atmospheric Background Station (LABS; 120.87°E, 23.47°N, 2862 m a.s.l.) to discuss the atmospheric Hg export from the East Asian continent. Twenty-four hour-integrated total atmospheric Hg (THg) samples were manually collected in Fu-guei-jiao and Mt. Bamboo in 2007-2008 and quantified by dual amalgamation CVAFS. On the other hand, continuous measurements of gaseous elemental Hg (GEM), reactive gaseous Hg (RGM), and particulate Hg (PHg) at LABS began since April 13, 2006 using the Tekran 2537A/1130/1135 speciation system. Mean(±S.D.) THg concentrations were 2.09±0.71 and 1.86±0.50 ng m-3 for Fu-guei-jiao and Mt. Bamboo, respectively. At LABS between April 2006 and April 2009, the mean(±S.D.) concentrations of GEM, RGM and PHg were 1.77±0.54 ng m-3, 22.4±43.8 pg m-3 and 6.3±10.9 pg m-3, respectively. Evident seasonal distribution in THg/GEM concentrations was observed at all sites with higher values usually occurred between fall and spring when the air masses were mainly from the East Asian continent, indicating the influence of the East Asian atmospheric Hg outflow. This also demonstrated that the atmospheric Hg export is occurring both in the boundary layer and in the free troposphere. Concentrations of PHg were usually low at LABS; however, elevated values were detected in spring when the Indochina Peninsula biomass burning plumes frequently affected

Identification of an exported heat shock protein 70 in Plasmodium falciparum

Full Text Available Host cell remodelling is a hallmark of malaria pathogenesis. It involves protein folding, unfolding and trafficking events and thus participation of chaperones such as Hsp70s and Hsp40s is well speculated. Until recently, only Hsp40s were thought to be the sole representative of the parasite chaperones in the exportome. However, based on the re-annotated Plasmodium falciparum genome sequence, a putative candidate for exported Hsp70 has been reported, which otherwise was known to be a pseudogene. We raised a specific antiserum against a C-terminal peptide uniquely present in PfHsp70-x. Immunoblotting and immunofluorescence-based approaches in combination with sub-cellular fractionation by saponin and streptolysin-O have been taken to determine the expression and localization of PfHsp70-x in infected erythrocyte. The re-annotated sequence of PfHsp70-x reveals it to be a functional protein with an endoplasmic reticulum signal peptide. It gets maximally expressed at the schizont stage of intra-erythrocytic life cycle. Majority of the protein localizes to the parasitophorous vacuole and some of it gets exported to the erythrocyte compartment where it associates with Maurer’s clefts. The identification of an exported parasite Hsp70 chaperone presents us with the fact that the parasite has evolved customized chaperones which might be playing crucial roles in aspects of trafficking and host cell remodelling.

Pancreatic β-cells possess a highly active protein synthetic and export machinery in the endoplasmic reticulum (ER) to accommodate the massive production of proinsulin. ER homeostasis is vital for β-cell functions and is maintained by the delicate balance between protein synthesis, folding, export, and degradation. Disruption of ER homeostasis by diabetes-causing factors leads to β-cell death. Among the 4 components to maintain ER homeostasis in β-cells, the role of ER export in insulin biogenesis is the least understood. To address this knowledge gap, the present study investigated the molecular mechanism of proinsulin ER export in MIN6 cells and primary islets. Two inhibitory mutants of the secretion-associated RAS-related protein (Sar)1 small GTPase, known to specifically block coat protein complex II (COPII)-dependent ER export, were overexpressed in β-cells using recombinant adenoviruses. Results from this approach, as well as small interfering RNA-mediated Sar1 knockdown, demonstrated that defective Sar1 function blocked proinsulin ER export and abolished its conversion to mature insulin in MIN6 cells, isolated mouse, and human islets. It is further revealed, using an in vitro vesicle formation assay, that proinsulin was packaged into COPII vesicles in a GTP- and Sar1-dependent manner. Blockage of COPII-dependent ER exit by Sar1 mutants strongly induced ER morphology change, ER stress response, and β-cell apoptosis. These responses were mediated by the PKR (double-stranded RNA-dependent kinase)-like ER kinase (PERK)/eukaryotic translation initiation factor 2α (p-eIF2α) and inositol-requiring protein 1 (IRE1)/x-box binding protein 1 (Xbp1) pathways but not via activating transcription factor 6 (ATF6). Collectively, results from the study demonstrate that COPII-dependent ER export plays a vital role in insulin biogenesis, ER homeostasis, and β-cell survival.

Endoplasmic reticulum transport of glutathione by Sec61 is regulated by Ero1 and Bip

In the endoplasmic reticulum (ER), Ero1 catalyzes disulfide bond formation and promotes glutathione (GSH) oxidation to GSSG. Since GSSG cannot be reduced in the ER, maintenance of the ER glutathione redox state and levels likely depends on ER glutathione import and GSSG export. We used quantitative...... oxidation through Ero1 reductive activation, which inhibits glutathione import in a negative regulatory loop. During ER stress, transport is activated by UPR-dependent Ero1 induction, and cytosolic glutathione levels increase. Thus, the ER redox poise is tuned by reciprocal control of glutathione import...... by reduction, causing Bip oxidation and inhibition of glutathione transport. Coupling of glutathione ER import to Ero1 activation provides a basis for glutathione ER redox poise maintenance....

Dendritic cells (DCs) are highly capable of processing and presenting internalized exogenous antigens upon major histocompatibility class (MHC) I molecules also known as cross-presentation (CP). CP plays an important role not only in the stimulation of naïve CD8 + T cells and memory CD8 + T cells for infectious and tumor immunity but also in the inactivation of self-acting naïve T cells by T cell anergy or T cell deletion. Although the critical molecular mechanism of CP remains to be elucidated, accumulating evidence indicates that exogenous antigens are processed through endoplasmic reticulum-associated degradation (ERAD) after export from non-classical endocytic compartments. Until recently, characterizations of these endocytic compartments were limited because there were no specific molecular markers other than exogenous antigens. The method described here is a new vesicle isolation protocol, which allows for the purification of these endocytic compartments. Using this purified microsome, we reconstituted the ERAD-like transport, ubiquitination, and processing of the exogenous antigen in vitro, suggesting that the ubiquitin-proteasome system processed the exogenous antigen after export from this cellular compartment. This protocol can be further applied to other cell types to clarify the molecular mechanism of CP.

Background Cornu ammonis 3 (CA3) hippocampal neurons are resistant to global ischemia, whereas cornu ammonis (CA1) 1 neurons are vulnerable. Hamartin expression in CA3 neurons mediates this endogenous resistance via productive autophagy. Neurons lacking hamartin demonstrate exacerbated endoplasmic reticulum stress and increased cell death. We investigated endoplasmic reticulum stress responses in CA1 and CA3 regions following global cerebral ischemia, and whether pharmacological modulation of endoplasmic reticulum stress or autophagy altered neuronal viability . Methods In vivo: male Wistar rats underwent sham or 10 min of transient global cerebral ischemia. CA1 and CA3 areas were microdissected and endoplasmic reticulum stress protein expression quantified at 3 h and 12 h of reperfusion. In vitro: primary neuronal cultures (E18 Wistar rat embryos) were exposed to 2 h of oxygen and glucose deprivation or normoxia in the presence of an endoplasmic reticulum stress inducer (thapsigargin or tunicamycin), an endoplasmic reticulum stress inhibitor (salubrinal or 4-phenylbutyric acid), an autophagy inducer ([4'-(N-diethylamino) butyl]-2-chlorophenoxazine (10-NCP)) or autophagy inhibitor (3-methyladenine). Results In vivo, decreased endoplasmic reticulum stress protein expression (phospho-eIF2α and ATF4) was observed at 3 h of reperfusion in CA3 neurons following ischemia, and increased in CA1 neurons at 12 h of reperfusion. In vitro, endoplasmic reticulum stress inducers and high doses of the endoplasmic reticulum stress inhibitors also increased cell death. Both induction and inhibition of autophagy also increased cell death. Conclusion Endoplasmic reticulum stress is associated with neuronal cell death following ischemia. Neither reduction of endoplasmic reticulum stress nor induction of autophagy demonstrated neuroprotection in vitro, highlighting their complex role in neuronal biology following ischemia.

Export Margins, Price and Quantity of Belarus’s Export Growth

Full Text Available This paper examines the sources of Belarus’s export growth and decomposes export growth into extensive and intensive margins. This study also aims to determine export margins for intermediate and final goods and to determine the price and quantity components of the intensive export margin. In order to achieve the desired objectives, we use two methods for decomposing export growth, the count method and the export shares method. We analyse Belarus's export growth using export data at the HS-6 digit level for the 2004-2014 period. Our results show that Belarus's exports grew mainly due to growth in the price margin during the studied period 2004-2014. However, the extensive margin was important in export growth to some extent. Comparing the growth rate across final and intermediate goods reveals that although the share of final products in Belarus’s exports is not very big (18.9% in 2014, the average annual growth in exports of final products is higher than that of intermediate goods. Our investigation also shows that Belarus produces a wide range of commodities, but the share of the most of these commodities is not large; its exports depend on a restricted range of commodities. Moreover, most of the commodities are exported to Russia and Ukraine. Our results give us reason to assume that finding new markets for their new products is one of the main challenges for developing countries wishing to increase their exports by an extensive margin. This has important implications for how policy makers promote the trade and diversification of exports.

Biochemical and morphological characterization of light and heavy sarcoplasmic reticulum vesicles

Energy Technology Data Exchange (ETDEWEB)

Campbell, K.P.

1978-01-01

Light and heavy sarcoplasmic reticulum vesicles isolated from rabbit leg muscle have been used in a study of chloride-induced calcium release. The biochemical and morphological data indicate that light sarcoplasmic reticulum vesicles are derived from the longitudinal reticulum and heavy sarcoplasmic reticulum vesicles are derived from the terminal cisternae of the sarcoplasmic reticulum. The light and heavy sarcoplasmic reticulum vesicles were both able to accumulate calcium in the presence of ATP to amounts greater than 100 nmoles Ca/sup + +/ per mg of protein in less than one minute. Light and heavy sarcoplasmic reticulum vesicles each had a biphasic time course of calcium uptake. The initial uptake was followed by a rapid release after approximately one minute, of 30 to 40% of the accumulated calcium, which was then followed by a slower phase of calcium accumulation. Results indicate that the chloride induced release of calcium may be acting by two mechanisms, osmotic swelling and depolarization. The release of calcium from the light SR vesicles is probably due to osmotic swelling and the release of calcium from the heavy SR vesicles is probably due to depolarization.

Protein export through the bacterial flagellar type III export pathway.

Science.gov (United States)

Minamino, Tohru

2014-08-01

For construction of the bacterial flagellum, which is responsible for bacterial motility, the flagellar type III export apparatus utilizes both ATP and proton motive force across the cytoplasmic membrane and exports flagellar proteins from the cytoplasm to the distal end of the nascent structure. The export apparatus consists of a membrane-embedded export gate made of FlhA, FlhB, FliO, FliP, FliQ, and FliR and a water-soluble ATPase ring complex consisting of FliH, FliI, and FliJ. FlgN, FliS, and FliT act as substrate-specific chaperones that do not only protect their cognate substrates from degradation and aggregation in the cytoplasm but also efficiently transfer the substrates to the export apparatus. The ATPase ring complex facilitates the initial entry of the substrates into the narrow pore of the export gate. The export gate by itself is a proton-protein antiporter that uses the two components of proton motive force, the electric potential difference and the proton concentration difference, for different steps of the export process. A specific interaction of FlhA with FliJ located in the center of the ATPase ring complex allows the export gate to efficiently use proton motive force to drive protein export. The ATPase ring complex couples ATP binding and hydrolysis to its assembly-disassembly cycle for rapid and efficient protein export cycle.

Highlights: ► We found the putative nuclear export signal motif within human NANOG homeodomain. ► Leucine-rich residues are important for human NANOG homeodomain nuclear export. ► CRM1-specific inhibitor LMB blocked the potent human NANOG NES-mediated nuclear export. -- Abstract: NANOG is a homeobox-containing transcription factor that plays an important role in pluripotent stem cells and tumorigenic cells. To understand how nuclear localization of human NANOG is regulated, the NANOG sequence was examined and a leucine-rich nuclear export signal (NES) motif ( 125 MQELSNILNL 134 ) was found in the homeodomain (HD). To functionally validate the putative NES motif, deletion and site-directed mutants were fused to an EGFP expression vector and transfected into COS-7 cells, and the localization of the proteins was examined. While hNANOG HD exclusively localized to the nucleus, a mutant with both NLSs deleted and only the putative NES motif contained (hNANOG HD-ΔNLSs) was predominantly cytoplasmic, as observed by nucleo/cytoplasmic fractionation and Western blot analysis as well as confocal microscopy. Furthermore, site-directed mutagenesis of the putative NES motif in a partial hNANOG HD only containing either one of the two NLS motifs led to localization in the nucleus, suggesting that the NES motif may play a functional role in nuclear export. Furthermore, CRM1-specific nuclear export inhibitor LMB blocked the hNANOG potent NES-mediated export, suggesting that the leucine-rich motif may function in CRM1-mediated nuclear export of hNANOG. Collectively, a NES motif is present in the hNANOG HD and may be functionally involved in CRM1-mediated nuclear export pathway.

Methods for monitoring endoplasmic reticulum stress and the unfolded protein response.

LENUS (Irish Health Repository)

Samali, Afshin

2010-01-01

The endoplasmic reticulum (ER) is the site of folding of membrane and secreted proteins in the cell. Physiological or pathological processes that disturb protein folding in the endoplasmic reticulum cause ER stress and activate a set of signaling pathways termed the Unfolded Protein Response (UPR). The UPR can promote cellular repair and sustained survival by reducing the load of unfolded proteins through upregulation of chaperones and global attenuation of protein synthesis. Research into ER stress and the UPR continues to grow at a rapid rate as many new investigators are entering the field. There are also many researchers not working directly on ER stress, but who wish to determine whether this response is activated in the system they are studying: thus, it is important to list a standard set of criteria for monitoring UPR in different model systems. Here, we discuss approaches that can be used by researchers to plan and interpret experiments aimed at evaluating whether the UPR and related processes are activated. We would like to emphasize that no individual assay is guaranteed to be the most appropriate one in every situation and strongly recommend the use of multiple assays to verify UPR activation.

2018-05-01

Sarco(endo)plasmic reticulum calcium adenosine triphosphatase is responsible for transporting cytosolic calcium into the sarcoplasmic reticulum and endoplasmic reticulum to maintain calcium homeostasis. Sarco(endo)plasmic reticulum calcium adenosine triphosphatase is the dominant isoform expressed in cardiac tissue, which is regulated by endogenous protein inhibitors, post-translational modifications, hormones as well as microRNAs. Dysfunction of sarco(endo)plasmic reticulum calcium adenosine triphosphatase is associated with heart failure, which makes sarco(endo)plasmic reticulum calcium adenosine triphosphatase a promising target for heart failure therapy. This review summarizes current approaches to ameliorate sarco(endo)plasmic reticulum calcium adenosine triphosphatase function and focuses on phospholamban, an endogenous inhibitor of sarco(endo)plasmic reticulum calcium adenosine triphosphatase, pharmacological tools and gene therapies.

Hyperpolarization-activated cyclic nucleotide-gated 1 (HCN1) channels are widely expressed in the retina. In photoreceptors, the hyperpolarization-activated current (Ih) carried by HCN1 is important for shaping the light response. It has been shown in multiple systems that trafficking HCN1 channels to specific compartments is key to their function. The localization of HCN1 in photoreceptors is concentrated in the plasma membrane of the inner segment (IS). The mechanisms controlling this localization are not understood. We previously identified a di-arginine endoplasmic reticulum (ER) retention motif that negatively regulates the surface targeting of HCN1. In this study, we sought to identify a forward trafficking signal that could counter the function of the ER retention signal. We studied trafficking of HCN1 and several mutants by imaging their subcellular localization in transgenic X. laevis photoreceptors. Velocity sedimentation was used to assay the assembly state of HCN1 channels. We found the HCN1 N-terminus can redirect a membrane reporter from outer segments (OS) to the plasma membrane of the IS. The sequence necessary for this behavior was mapped to a 20 amino acid region containing a leucine-based ER export motif. The ER export signal is necessary for forward trafficking but not channel oligomerization. Moreover, this ER export signal alone counteracted the di-arginine ER retention signal. We identified an ER export signal in HCN1 that functions with the ER retention signal to maintain equilibrium of HCN1 between the endomembrane system and the plasma membrane.

different policy stance than typical in Africa. This is especially so in promoting export-oriented industry. If learning by exporting is a key driver of progress, then a fundamental reason for Africa's lack of transformation is likely to be the low policy priority given to export promotion in the past....... To enlarge the body of empirical evidence, we use an extensive 2005–2012 firm-level panel data set from Vietnam and separate out productivity effects of exporting due to self-selection. This allows us to conclude that firms actually learn by exporting. We also examine how this learning takes place. Our...... findings suggest that productivity gains are associated with moving to larger scale for foreign-owned firms with little evidence of subsequent learning on export markets. We find strong evidence to suggest that private domestic firms learn and accumulate knowledge from export markets with learning...

Nuclear export factor 1 (NXF1) exports mRNA to the cytoplasm after recruitment to mRNA by specific adaptor proteins. How and why cells use numerous different export adaptors is poorly understood. Here we critically evaluate members of the SR protein family (SRSF1-7) for their potential to act as NXF1 adaptors that couple pre-mRNA processing to mRNA export. Consistent with this proposal, >1000 endogenous mRNAs required individual SR proteins for nuclear export in vivo. To address the mechanism, transcriptome-wide RNA-binding profiles of NXF1 and SRSF1-7 were determined in parallel by individual-nucleotide-resolution UV cross-linking and immunoprecipitation (iCLIP). Quantitative comparisons of RNA-binding sites showed that NXF1 and SR proteins bind mRNA targets at adjacent sites, indicative of cobinding. SRSF3 emerged as the most potent NXF1 adaptor, conferring sequence specificity to RNA binding by NXF1 in last exons. Interestingly, SRSF3 and SRSF7 were shown to bind different sites in last exons and regulate 3' untranslated region length in an opposing manner. Both SRSF3 and SRSF7 promoted NXF1 recruitment to mRNA. Thus, SRSF3 and SRSF7 couple alternative splicing and polyadenylation to NXF1-mediated mRNA export, thereby controlling the cytoplasmic abundance of transcripts with alternative 3' ends. © 2016 Müller-McNicoll et al.; Published by Cold Spring Harbor Laboratory Press.

Specific binding of [3H]LY186126, an analogue of indolidan (LY195115), to cardiac membranes enriched in sarcoplasmic reticulum vesicles

LY186126 was found to be a potent inhibitor of type IV cyclic AMP phosphodiesterase located in the sarcoplasmic reticulum of canine cardiac muscle. This compound, a close structural analogue of indolidan (LY195115), was prepared in high specific activity, tritiated form to study the positive inotropic receptor(s) for cardiotonic phosphodiesterase inhibitors such as indolidan and milrinone. A high-affinity binding site for [ 3 H]LY186126 was observed (Kd = 4 nM) in purified preparations of canine cardiac sarcoplasmic reticulum vesicles. Binding was proportional to vesicle protein, was inactivated by subjecting membranes to proteolysis or boiling, and was dependent on added Mg2+. Scatchard analysis suggested the presence of a single class of binding sites in the membrane preparation. Indolidan, milrinone, and LY186126 (all at 1 microM) produced essentially complete displacement of bound [ 3 H]LY186126, while nifedipine, propranolol, and prazosin had little or no effect at this concentration. This represents the first reported use of a radioactive analogue to label the inotropic receptor for cardiotonic phosphodiesterase inhibitors. The results suggest that [ 3 H]LY186126 is a useful radioligand for examining the subcellular site(s) responsible for positive inotropic effects of these drugs

2011-12-01

Full Text Available Purpose: The main purpose of this paper is to examine perceived impediments to export involvement among non-exporting small and medium sized firms (SME's in Malawi. The study also examines levels of interest in exporting among the firms. Problem investigated: Many countries have programs aimed at promoting export involvement among SME's. Despite this, most SME's continue to ignore exporting as a viable business strategy. Information on perceived impediments to export involvement especially from the non-exporters' perspective is often lacking hence the need for this study. Methodology: Data was collected from 80 owner managers of non-exporting SME's. A structured questionnaire was the main instrument used to collect data. Personal interviews were also held with managers for the purposes of probing their answers to the questions in the questionnaire. Statistical Package for Social Science (SPSS version 18 was used to analyse the quantitative data obtained from use of the structured questionnaire. Qualitative data obtained through personal interviews was analysed used thematic analysis. Findings: The findings of the study showed significant levels of interest in exporting among the firms. The majority of the owner managers indicated willingness to exploit export opportunities that may be readily available to them. The findings however showed that just over half of the respondents had discussed or investigated the possibility of exporting before. On impediments to exporting, the findings showed that managers perceive many factors as important impediments to their firm's involvement in exporting. The top two most important impediments were internal to the firm and related to human resource issues. They included insufficient knowledge about export opportunities and lack of personnel knowledgeable in exporting. Originality and value of the research: A review of literature shows that most export promotion studies tend to focus more on issues relating to

Niemann-Pick C1 (NPC1), a membrane protein of lysosomes, is required for the export of cholesterol derived from receptor-mediated endocytosis of LDL. Lysosomal cholesterol export is reportedly inhibited by itraconazole, a triazole that is used as an antifungal drug [Xu et al. (2010) Proc Natl Acad Sci USA 107:4764-4769]. Here we show that posaconazole, another triazole, also blocks cholesterol export from lysosomes. We prepared P-X, a photoactivatable cross-linking derivative of posaconazole. P-X cross-linked to NPC1 when added to intact cells. Cross-linking was inhibited by itraconazole but not by ketoconazole, an imidazole that does not block cholesterol export. Cross-linking of P-X was also blocked by U18666A, a compound that has been shown to bind to NPC1 and inhibit cholesterol export. P-X also cross-linked to purified NPC1 that was incorporated into lipid bilayer nanodiscs. In this in vitro system, cross-linking of P-X was inhibited by itraconazole, but not by U18666A. P-X cross-linking was not prevented by deletion of the N-terminal domain of NPC1, which contains the initial binding site for cholesterol. In contrast, P-X cross-linking was reduced when NPC1 contained a point mutation (P691S) in its putative sterol-sensing domain. We hypothesize that the sterol-sensing domain has a binding site that can accommodate structurally different ligands.

Biochemical and morphological characterization of light and heavy sarcoplasmic reticulum vesicles

Energy Technology Data Exchange (ETDEWEB)

Campbell, Kevin Peter [Univ. of Rochester, NY (United States)

1978-01-01

Light (30 to 32.5% sucrose) and heavy (38.5 to 42% sucrose) sarcoplasmic reticulum vesicles (LSR,HSR) were isolated from rabbit leg muscle using a combination of differential centrifugation and isopycnic zonal ultracentrifugation. Thin-section electron microscopy of LSR vesicles reveals empty vesicles of various sizes and shapes whereas the HSR vesicles appear as rounded vesicles of uniform size filled with electron dense material, similar to that seen in the terminal cisternae of the sarcoplasmic reticulum. The sucrose HSR vesicles have an additional morphological feature which appears as membrane projections that resemble the SR feet. The freeze-fracture morphology of either type of SR reveals an asymmetric distribution of intramembraneous particles in the same orientation and distribution as the sarcoplasmic reticulum in vivo. Biochemical studies were made on the content of Ca, Mg, ATPase, and protein of the vesicles and phosphorylation of the vesicles. The biochemical and morphological data indicate that the LSR is derived from the longitudinal sarcoplasmic reticulum and the HSR is derived from the terminal cisternae of the sarcoplasmic reticulum, contains junctional SR membrane and has three unique proteins (calsequestrin, an intrinsic 30,000 dalton protein and a 9000 dalton proteolipid).

Investigation of function similarities between the sarcoplasmic reticulum and platelet calcium-dependent adenosinetriphosphatases with the inhibitors quercetin and calmidazolium

International Nuclear Information System (INIS)

Fischer, T.H.; Campbell, K.P.; White, G.C. II

1987-01-01

The platelet and skeletal sarcoplasmic reticulum calcium-dependent adenosinetriphosphatases (Ca 2+ -ATPases) were functionally compared with respect to substrate activation by steady-state kinetic methods using the inhibitors quercetin and calmidazolium. Quercetin inhibited platelet and sarcoplasmic reticulum Ca 2+ -ATPase activities in a dose-dependent manner with IC 50 values of 25 and 10 μM, respectively. Calmidazolium also inhibited platelet and sarcoplasmic reticulum Ca 2+ -ATPase activities, with half-maximal inhibition measured at 5 and 4 μM, respectively. Both inhibitors also affected the [ 45 Ca] calcium transport activity of intact platelet microsomes at concentrations similar to those which reduced Ca 2+ -ATPase activity. These inhibitors were then used to examine substrate ligation by the platelet and sarcoplasmic reticulum calcium pump proteins. For both Ca 2+ -ATPase proteins, quercetin has an affinity for the E-Ca 2 (fully ligated with respect to calcium at the exterior high-affinity calcium binding sites, unligated with respect to ATP) conformational state of the protein that is approximately 10-fold grater than for other conformational states in the hydrolytic cycle. Quercetin can thus be considered a competitive inhibitor of the calcium pump proteins with respect to ATP. In contrast to the effect of quercetin, calmidazolium interacts with the platelet and sarcoplasmic reticulum Ca 2+ -ATPases in an uncompetitive manner. The dissociation constants for this inhibitor for the different conformational states of the calcium pump proteins were similar, indicating that calmidazolium has equal affinity for all of the reaction intermediates probed. These observations indicate that the substrate ligation processes are similar for the two pump proteins. This supports the concept that the hydrolytic cycles of the two proteins are comparable

Sharing the load: Mex67-Mtr2 cofunctions with Los1 in primary tRNA nuclear export.

Eukaryotic transfer RNAs (tRNAs) are exported from the nucleus, their site of synthesis, to the cytoplasm, their site of function for protein synthesis. The evolutionarily conserved β-importin family member Los1 (Exportin-t) has been the only exporter known to execute nuclear export of newly transcribed intron-containing pre-tRNAs. Interestingly, LOS1 is unessential in all tested organisms. As tRNA nuclear export is essential, we previously interrogated the budding yeast proteome to identify candidates that function in tRNA nuclear export. Here, we provide molecular, genetic, cytological, and biochemical evidence that the Mex67-Mtr2 (TAP-p15) heterodimer, best characterized for its essential role in mRNA nuclear export, cofunctions with Los1 in tRNA nuclear export. Inactivation of Mex67 or Mtr2 leads to rapid accumulation of end-matured unspliced tRNAs in the nucleus. Remarkably, merely fivefold overexpression of Mex67-Mtr2 can substitute for Los1 in los1 Δ cells. Moreover, in vivo coimmunoprecipitation assays with tagged Mex67 document that the Mex67 binds tRNAs. Our data also show that tRNA exporters surprisingly exhibit differential tRNA substrate preferences. The existence of multiple tRNA exporters, each with different tRNA preferences, may indicate that the proteome can be regulated by tRNA nuclear export. Thus, our data show that Mex67-Mtr2 functions in primary nuclear export for a subset of yeast tRNAs. © 2017 Chatterjee et al.; Published by Cold Spring Harbor Laboratory Press.

Impact of high cholesterol and endoplasmic reticulum stress on metabolic diseases: An updated mini-review

Directory of Open Access Journals (Sweden)

Erdi Sozen

2017-08-01

Full Text Available Endoplasmic reticulum (ER is the major site of protein folding and calcium storage. Beside the role of ER in protein homeostasis, it controls the cholesterol production and lipid-membrane biosynthesis as well as surviving and cell death signaling mechanisms in the cell. It is well-documented that elevated plasma cholesterol induces adverse effects in cardiovascular diseases (CVDs, liver disorders, such as non-alcoholic fatty liver disease (NAFLD, non-alcoholic steatosis hepatitis (NASH, and metabolic diseases which are associated with oxidative and ER stress. Recent animal model and human studies have showed high cholesterol and ER stress as an emerging factors involved in the development of many metabolic diseases. In this review, we will summarize the crucial effects of hypercholesterolemia and ER stress response in the pathogenesis of CVDs, NAFLD/NASH, diabetes and obesity which are major health problems in western countries. Keywords: Endoplasmic reticulum stress, High cholesterol, Cardiovascular diseases, Non-alcoholic fatty liver disease, Non-alcoholic steatosis hepatitis

Exporter Price Premia?

DEFF Research Database (Denmark)

Jäkel, Ina Charlotte; Sørensen, Allan

This paper provides new evidence on manufacturing firms' output prices: in Denmark, on average, exported varieties are sold at a lower price (i.e. a negative exporter price premium) relative to only domestically sold varieties. This finding stands in sharp contrast to previous studies, which have...... found positive exporter price premia. We also document that the exporter price premium varies substantially across products (both in terms of sign and magnitude). We show that in a standard heterogeneous firms model with heterogeneity in quality as well as production efficiency there is indeed no clear......-cut prediction on the sign of the exporter price premium. However, the model unambiguously predicts a negative exporter price premium in terms of quality-adjusted prices, i.e. prices per unit of quality. This prediction is broadly borne out in the Danish data: while the magnitude of the premium varies across...

Dynamics of Phosphorus export from small forested catchments in low mountain ranges in Germany

Science.gov (United States)

Julich, Stefan; Julich, Dorit; Benning, Raphael; Feger, Karl-Heinz

2017-04-01

Phosphorus (P) plays an important role in the nutrition of forest ecosystem. The transport of P in forest soils predominantly occurs along preferential water flow pathways bypassing large parts of the soil matrix. Therefore, rapid flow processes by preferential flow and/or during storm events may lead to significant P losses from forest soils. However only little knowledge about the dynamics, magnitude and driving processes of P exports into surface water exist. In this contribution, we present the results of two studies where two small forested catchments have been monitored for a period around 3 years. Both catchments are situated in low mountain ranges in Saxony (catchment size 21 ha) and Thuringia (catchment size 5 ha) representing medium P contents in the topsoil of 1142 mg kg-1 and 834 mg kg-1 respectively. During the regular sampling (monthly to weekly sampling frequency), the mean Total-P concentrations of 23 μg L-1(Thuringian Site) and 8 μg L-1(Saxonian Site) have been measured. However, during single storm events Total-P concentrations increased considerably with maximum concentrations of 134 μg L-1(Thuringian Site) and 203 μg L-1(Saxonian Site). Our findings indicate that during storm events, especially after longer dry periods, significant amounts of phosphorus can be exported from forest ecosystems. Comparison of discharge-concentration patterns of Total-P, Nitrogen and DOC, as well as dye tracer experiments, suggest that preferential flow along biopores and stone surfaces, and the interface between mineral soil and litter layer are main pathways of export from forests. For the site in Saxony we calculated mean annual export rates of 32.8 to 33.5 g ha-1 a-1 based on the weekly sampling with different load calculation methods (flow weighted methods up to linear regression models). If the events are included into the annual load calculation the mean annual export fluxes increase from 47.8 to 58.6 g ha-1 a-1 based on the different load calculation

Canadian solar export market study. Export policy recommendations

Energy Technology Data Exchange (ETDEWEB)

1983-11-01

This report outlines policies and recommendations on the export of Canadian solar equipment and technology, with a view toward stimulating the domestic solar industry. The current picture is of an industry which is relatively small, operates in a competitive domestic market with low profit margins, and needs assistance in order to break into the world market. A number of recommendations are therefore made on the main thrust of industry and government solar export development activities. An export development program is described which includes a strategy of concentrating on a limited number of product lines, namely: low-temperature solar heating systems for recreational applications, integrated residential water heating systems, prepackaged commercial water heating systems, and industrial pre-heat systems. It is also recommended that this strategy be directed only at a limited number of target countries where the market justifies such activity. Market research, international cooperation agreements, promotional services, and proper export organization are also needed.

Porcine malignant hyperthermia susceptibility: hypersensitive calcium-release mechanism of skeletal muscle sarcoplasmic reticulum.

Science.gov (United States)

O'Brien, P J

1986-01-01

This study tested the hypothesis that calcium-release from sarcoplasmic reticulum isolated from malignant hyperthermia swine had abnormal concentration-dependency on release modulators. Halothane stimulated half-maximal calcium-release at similar concentrations for malignant hyperthermia and control sarcoplasmic reticulum (0.10 +/- 0.04 mM). However, concentrations causing half-maximal calcium-release were lower for malignant hyperthermia sarcoplasmic reticulum (P less than 0.001) by an order of magnitude for Ca2+ (28.1 +/- 8.3 versus 1.23 +/- 0.45 nM), adenosine triphosphate (0.33 +/- 0.09 versus 0.023 +/- 0.014 mM) and caffeine (7.79 +/- 1.56 versus 0.80 +/- 0.44 mM). Half-maximal inhibition by Mg2+ occurred at threefold higher concentrations for malignant hyperthermia sarcoplasmic reticulum (0.23 +/- 0.02 versus 0.78 +/- 0.17 mM). The Ca2+-sensitivity curves for calcium-release by sarcoplasmic reticulum isolated from heterozygotes for the malignant hyperthermia-defect were indistinguishable from the averages of the curves for controls and malignant hyperthermia-homozygotes. Results of this study suggest that malignant hyperthermia is initiated due to a hypersensitive calcium-release mechanism which is inherited in an autosomal, codominant pattern and may be diagnosed using calcium-release sensitivity-tests on isolated sarcoplasmic reticulum.

An exporter's checklist

International Nuclear Information System (INIS)

Englot, P.

1995-01-01

The benefits of exporting goods and services was discussed. The article listed a summary of issues which could be referred to to assist with the development of an effective plan to export. Some issues to consider were: (1) analysis of the export market, such as political and cultural issues, local legislation, competition, infrastructure, transportation and logistics, (2) internal issues, such as people, equipment, capital, time, understanding of the risks, relocation and identification of all costs, (3) sources of support such as banks, government and transporters, (4) development of a solid payment plan. It was concluded that exporting was not for the faint-hearted. It can be expensive, and time consuming, however, if approached in the right spirit it could be highly rewarding. As a rule of thumb, the probability of success was said to be directly related to the amount of effort put into the preparatory phase. Potential exporters were reminded of the very strong infrastructure that exists in Canada to promote and support export initiatives, including all levels of government, financial institutions, freight forwarders and innumerable consultant/specialists

The effect on the cardiac sarcoplasmic reticulum of an atherogenic (1% cholesterol) diet fed during the neonatal vs the juvenile period of life was studied in Yorkshire swine. Male piglets were randomly assigned at birth to 1 of 4 groups: group I (control), group II (lactation feeding), group III (juvenile period feeding) and group IV (lactation and juvenile feeding). All animals were killed at 55 weeks of age and cardiac sarcoplasmic reticulum (SR) isolated for assay of calcium uptake, Ca 2+ -Mg 2+ ATPase activity, and lipid analysis by thin-layer chromatography and gas chromatography. The amount of cholesterol/mg SR protein and the cholesterol/phospholipid ratio were higher in the animals fed during lactation (groups II and IV) and lower in those fed only during the juvenile period (group III). Phospholipid fatty acid patterns as measured by gas chromatography were unaltered in any group. Calcium uptake was markedly diminished in all experimental conditions: group II 47%, group III 65% and group IV 96%. Compared to the observed changes in calcium transport, the ATP hydrolytic activity was relatively less affected. Only in group IV a significant decrease (41%) was seen. Groups II and III show no change in ATP hydrolytic activity. The decrease in calcium uptake and altered cholesterol/phospholipid ratio without effect on ATP hydrolytic activity is consistent with an uncoupling of calcium transport related to the atherogenic diet in early life.

Nuclear safety aspects of exported replicate nuclear power plants and associated problems

International Nuclear Information System (INIS)

Kern, H.G.

1978-01-01

The standardization of the export nuclear power plant is being pursued with the concept of replication. This concept entails using another exported Nuclear Power Plant (NPP) as the base design and adapting it to a new site. The general ground rule applied to this concept is upgrading the design where necessary and duplicating the design where it is superior. Such continuous improvement will result in a standard export NPP that incorporates design features which will make it essentially acceptable for any suitable site. The advantages of replication are, therefore, boundless. However, the replication mode requires superior design control by the engineer to assure that only improvements alter the base design. With this concept, the replicating engineer is essentially assigned the responsiblity of safeguarding the standard export plant design. He is delegated the task of filtering the design such that only the conservative aspects prevail. Tight control of design changes via properly administered procedures is necessary to assure that no unforeseen compromises are made in designs which have already achieved optimization. Techniques to accomplish successful replication include, among others, the use of PCNs, system cognizant engineers, design verfication review, and the participation of all engineering disciplines in the development of the project schedule.

Future export markets for renewable energies have enormous potential, yet business-as-usual investment trends will not achieve that potential, write Giulio Volpi and Liam Salter. They examine the role that Export Credit Agencies - which have provided essential support for exports in the conventional energy business - could play in aiding the renewables sector, characterized as it is by small- and medium-sized enterprises. This new role will require certain reforms - but without those reforms the Export Credit Agencies will simply not be providing relevant services to new technologies and new market players. (author)

This article analyses export taxes in a Bertrand duopoly with product differentiation, where a home and a foreign firm both export to a third-country market. It is shown that the maximum-revenue export tax always exceeds the optimum-welfare export tax. In a Nash equilibrium in export taxes, the country with the low cost firm imposes the largest export tax. The results under Bertrand duopoly are compared with those under Cournot duopoly. It is shown that the absolute value of the export subsid...

A political economy of China's export restrictions on rare earth elements

Energy Technology Data Exchange (ETDEWEB)

Pothen, Frank [Zentrum fuer Europaeische Wirtschaftsforschung GmbH (ZEW), Mannheim (Germany); Fink, Kilian [Frankfurt Univ. (Germany)

2015-04-20

We investigate why governments restrict exports of exotic raw materials taking rare earth elements as a case study. Trade restrictions on exotic materials do not have immediate macroeconomic effects. Relocating rare earth intensive industries is found to be the main reason behind China's export barriers. They are part of a more extensive strategy aiming at creating comparative advantages in these sectors and at overcoming path dependencies. Moreover, export barriers serve as a second-best instrument to reduce pollution and to slow down the depletion of exhaustible resources. Growing domestic rare earth consumption renders those increasingly ineffective. Rising reliance on mine-site regulation indicates that this fact is taken into account. Rare earth extraction is dominated by a few large companies; the demand side is dispersed. That speaks against successful lobbying for export restrictions. It appears as if the export barriers are set up to compensate mining firms.

In an earlier study (Kimura, Y., Kurzydlowski, K., Tada, M., and MacLennan, D. H. (1997) J. Biol. Chem. 272, 15061-15064), mutation of amino acids on one face of the phospholamban (PLN) transmembrane helix led to loss of PLN inhibition of sarco(endo)plasmic reticulum Ca(2+)-ATPase (SERCA) molecules. This helical face was proposed to form a site of PLN interaction with a transmembrane helix in SERCA molecules. To determine whether predicted transmembrane helices M4, M5, M6, or M8 in SERCA1a interact with PLN, SERCA1a mutants were co-expressed with wild-type PLN and effects on Ca(2+) dependence of Ca(2+) transport were measured. Wild-type inhibitory interactions shifted apparent Ca(2+) affinity of SERCA1a by an average of -0.34 pCa units, but four of the seven mutations in M4 led to a more inhibitory shift in apparent Ca(2+) affinity, averaging -0.53 pCa units. Seven mutations in M5 led to an average shift of -0.32 pCa units and seven mutations in M8 led to an average shift of -0.30 pCa units. Among 11 mutations in M6, 1, Q791A, increased the inhibitory shift (-0.59 pCa units) and 5, V795A (-0.11), L802A (-0.07), L802V (-0.04), T805A (-0.11), and F809A (-0.12), reduced the inhibitory shift, consistent with the view that Val(795), Leu(802), Thr(805), and Phe(809), located on one face of a predicted M6 helix, form a site in SERCA1a for interaction with PLN. Those mutations in M4, M6, or M8 of SERCA1a that enhanced PLN inhibitory function did not enhance PLN physical association with SERCA1a, but mutants V795A and L802A in M6, which decreased PLN inhibitory function, decreased physical association, as measured by co-immunoprecipitation. In related studies, those PLN mutants that gained inhibitory function also increased levels of co-immunoprecipitation of wild-type SERCA1a and those that lost inhibitory function also reduced association, correlating functional interaction sites with physical interaction sites. Thus, both functional and physical data confirm that PLN

Specific binding of (/sup 3/H)LY186126, an analogue of indolidan (LY195115), to cardiac membranes enriched in sarcoplasmic reticulum vesicles

Energy Technology Data Exchange (ETDEWEB)

Kauffman, R.F.; Utterback, B.G.; Robertson, D.W.

1989-05-01

LY186126 was found to be a potent inhibitor of type IV cyclic AMP phosphodiesterase located in the sarcoplasmic reticulum of canine cardiac muscle. This compound, a close structural analogue of indolidan (LY195115), was prepared in high specific activity, tritiated form to study the positive inotropic receptor(s) for cardiotonic phosphodiesterase inhibitors such as indolidan and milrinone. A high-affinity binding site for (/sup 3/H)LY186126 was observed (Kd = 4 nM) in purified preparations of canine cardiac sarcoplasmic reticulum vesicles. Binding was proportional to vesicle protein, was inactivated by subjecting membranes to proteolysis or boiling, and was dependent on added Mg2+. Scatchard analysis suggested the presence of a single class of binding sites in the membrane preparation. Indolidan, milrinone, and LY186126 (all at 1 microM) produced essentially complete displacement of bound (/sup 3/H)LY186126, while nifedipine, propranolol, and prazosin had little or no effect at this concentration. This represents the first reported use of a radioactive analogue to label the inotropic receptor for cardiotonic phosphodiesterase inhibitors. The results suggest that (/sup 3/H)LY186126 is a useful radioligand for examining the subcellular site(s) responsible for positive inotropic effects of these drugs.

Aggregation and retention of human urokinase type plasminogen activator in the yeast endoplasmic reticulum

Directory of Open Access Journals (Sweden)

Smirnov Vladimir N

2002-10-01

Full Text Available Abstract Background Secretion of recombinant proteins in yeast can be affected by their improper folding in the endoplasmic reticulum and subsequent elimination of the misfolded molecules via the endoplasmic reticulum associated protein degradation pathway. Recombinant proteins can also be degraded by the vacuolar protease complex. Human urokinase type plasminogen activator (uPA is poorly secreted by yeast but the mechanisms interfering with its secretion are largely unknown. Results We show that in Hansenula polymorpha overexpression worsens uPA secretion and stimulates its intracellular aggregation. The absence of the Golgi modifications in accumulated uPA suggests that aggregation occurs within the endoplasmic reticulum. Deletion analysis has shown that the N-terminal domains were responsible for poor uPA secretion and propensity to aggregate. Mutation abolishing N-glycosylation decreased the efficiency of uPA secretion and increased its aggregation degree. Retention of uPA in the endoplasmic reticulum stimulates its aggregation. Conclusions The data obtained demonstrate that defect of uPA secretion in yeast is related to its retention in the endoplasmic reticulum. Accumulation of uPA within the endoplasmic reticulum disturbs its proper folding and leads to formation of high molecular weight aggregates.

Advances in three-dimensional secondary ion mass spectrometry (SIMS) imaging have enabled visualizing the subcellular distributions of various lipid species within individual cells. However, the difficulty of locating organelles using SIMS limits efforts to study their lipid compositions. Here, the authors have assessed whether endoplasmic reticulum (ER)-Tracker Blue White DPX ® , which is a commercially available stain for visualizing the endoplasmic reticulum using fluorescence microscopy, produces distinctive ions that can be used to locate the endoplasmic reticulum using SIMS. Time-of-flight-SIMS tandem mass spectrometry (MS 2 ) imaging was used to identify positively and negatively charged ions produced by the ER-Tracker stain. Then, these ions were used to localize the stain and thus the endoplasmic reticulum, within individual human embryonic kidney cells that contained higher numbers of endoplasmic reticulum-plasma membrane junctions on their surfaces. By performing MS 2 imaging of selected ions in parallel with the precursor ion (MS 1 ) imaging, the authors detected a chemical interference native to the cell at the same nominal mass as the pentafluorophenyl fragment from the ER-Tracker stain. Nonetheless, the fluorine secondary ions produced by the ER-Tracker stain provided a distinctive signal that enabled locating the endoplasmic reticulum using SIMS. This simple strategy for visualizing the endoplasmic reticulum in individual cells using SIMS could be combined with existing SIMS methodologies for imaging intracellular lipid distribution and to study the lipid composition within the endoplasmic reticulum.

Endoplasmic Reticulum Stress and Associated ROS

Full Text Available The endoplasmic reticulum (ER is a fascinating network of tubules through which secretory and transmembrane proteins enter unfolded and exit as either folded or misfolded proteins, after which they are directed either toward other organelles or to degradation, respectively. The ER redox environment dictates the fate of entering proteins, and the level of redox signaling mediators modulates the level of reactive oxygen species (ROS. Accumulating evidence suggests the interrelation of ER stress and ROS with redox signaling mediators such as protein disulfide isomerase (PDI-endoplasmic reticulum oxidoreductin (ERO-1, glutathione (GSH/glutathione disuphide (GSSG, NADPH oxidase 4 (Nox4, NADPH-P450 reductase (NPR, and calcium. Here, we reviewed persistent ER stress and protein misfolding-initiated ROS cascades and their significant roles in the pathogenesis of multiple human disorders, including neurodegenerative diseases, diabetes mellitus, atherosclerosis, inflammation, ischemia, and kidney and liver diseases.

Demand Uncertainty: Exporting Delays and Exporting Failures

DEFF Research Database (Denmark)

Nguyen, Daniel Xuyen

2012-01-01

This paper presents a model of trade that explains why firms wait to export and why many exporters fail. Firms face uncertain demands that are only realized after the firm enters the destination. The model retools the timing of the resolution of uncertainty found in models with heterogeneity...... of firm productivity. This retooling addresses several shortcomings. First, the imperfect correlation of demands reconciles the sales variation observed in and across destinations. Second, since demands for the firm's output are correlated across destinations, a firm can use previously realized demands...... to forecast unknown demands in untested destinations. The option to forecast demands causes firms to delay exporting in order to gather more information about foreign demand. Third, since uncertainty is resolved after entry, many firms enter a destination and then exit after learning that they cannot profit...

Exports of petroleum products, 1987

International Nuclear Information System (INIS)

1988-04-01

A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1987 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 22,200 m 3 /d in 1987, up 15% from 1986 levels. Exports of middle distillates and aviation fuel had the largest gains in 1987. Export prices for light petroleum products stayed relatively close to USA spot prices. The heavy fuel oil price was below the New York spot price in the beginning of 1987 but remained close for the rest of the year. Canada's petroleum products exports were made to 5 countries while imports came from at least 13 countries. The USA remained Canada's largest trading partner in petroleum products. Exports to Japan and the Far East rose ca 60% over 1986. Product outturns for export were 9% of total Canadian refinery throughput. Exports of aviation turbine fuel from Ontario began in April 1987. The top single exporter in Canada was Irving Oil Ltd. with 2,485,000 m 3 . Irving was also the top exporter in 1986. 11 figs., 4 tabs

One approach to describing the multilateral nuclear export controls is to do it according to time. This led to an interesting discovery, i.e. multilateral export controls have been defined by four distinct periods, the forst two of abut five years each, the second two about twice as long. These time periods have another interesting property. The two suppliers groups, which we will discuss in detail, have alternated in dominance over nearly thirty years. After describing the historical developments, the status of the present situation in multilateral nuclear export controls is examined, with the strengths and weaknesses. The future of multilateral nuclear export controls and possible ways that might be taken are considered

2016-11-01

The Kerguelen Plateau is characterized by a naturally Fe-fertilized phytoplankton bloom that extends more than 1000 km downstream in the Antarctic Circumpolar Current. During the KEOPS2 study, in austral spring, we measured particulate nitrogen (PN), biogenic silica (BSi) and particulate iron (PFe) export fluxes in order to investigate how the natural fertilization impacts the stoichiometry and the magnitude of export fluxes and therefore the efficiency of the biological carbon pump. At 9 stations, we estimated elemental export fluxes based on element concentration to 234Th activity ratios for particulate material collected with in-situ pumps and 234Th export fluxes (Planchon et al., 2015). This study revealed that the natural Fe-fertilization increased export fluxes but to variable degrees. Export fluxes for the bloom impacted area were compared with those of a high-nutrient, low-chlorophyll (HNLC), low-productive reference site located to the south-west of Kerguelen and which had the lowest BSi and PFe export fluxes (2.55 mmol BSi m-2 d-1 and 1.92 μmol PFem-2 d-1) and amongst the lowest PN export flux (0.73 mmol PN m-2 d-1). The impact of the Fe fertilization was the greatest within a meander of the polar front (PF), to the east of Kerguelen, with fluxes reaching 1.26 mmol PN m-2 d-1; 20.4 mmol BSi m-2 d-1 and 22.4 μmol PFe m-2 d-1. A highly productive site above the Kerguelen Plateau, on the contrary, was less impacted by the fertilization with export fluxes reaching 0.72 mmol PN m-2 d-1; 4.50 mmol BSi m-2 d-1 and 21.4 μmol PFe m-2 d-1. Our results suggest that ecosystem features (i.e. type of diatom community) could play an important role in setting the magnitude of export fluxes of these elements. Indeed, for the PF meander, the moderate productivity was sustained by the presence of large and strongly silicified diatom species while at the higher productivity sites, smaller and slightly silicified diatoms dominated. Interestingly, our results suggest that

BiP clustering facilitates protein folding in the endoplasmic reticulum.

Directory of Open Access Journals (Sweden)

Marc Griesemer

2014-07-01

Full Text Available The chaperone BiP participates in several regulatory processes within the endoplasmic reticulum (ER: translocation, protein folding, and ER-associated degradation. To facilitate protein folding, a cooperative mechanism known as entropic pulling has been proposed to demonstrate the molecular-level understanding of how multiple BiP molecules bind to nascent and unfolded proteins. Recently, experimental evidence revealed the spatial heterogeneity of BiP within the nuclear and peripheral ER of S. cerevisiae (commonly referred to as 'clusters'. Here, we developed a model to evaluate the potential advantages of accounting for multiple BiP molecules binding to peptides, while proposing that BiP's spatial heterogeneity may enhance protein folding and maturation. Scenarios were simulated to gauge the effectiveness of binding multiple chaperone molecules to peptides. Using two metrics: folding efficiency and chaperone cost, we determined that the single binding site model achieves a higher efficiency than models characterized by multiple binding sites, in the absence of cooperativity. Due to entropic pulling, however, multiple chaperones perform in concert to facilitate the resolubilization and ultimate yield of folded proteins. As a result of cooperativity, multiple binding site models used fewer BiP molecules and maintained a higher folding efficiency than the single binding site model. These insilico investigations reveal that clusters of BiP molecules bound to unfolded proteins may enhance folding efficiency through cooperative action via entropic pulling.

1989-06-01

Effective June 1, 1985, licensing and charging of oil exports ended. The Board now issues export orders specifying neither volumes nor prices and covering an exportation period of up to 1 year for light crude oil and up to 2 years for heavy crude oil, available on request to both Canadian and foreign companies. The Board has assumed a monitoring role, and export prices and volumes are reported monthly by exporters. This annual report provides a review of the volumes and prices associated with the supply and disposition of Canadian crude oil during 1988. Highlights are given with detailed information on prices, both internationally, in Canada, and the Chicago posted price by light or heavy crude, and on volumes including capacity and disposition in both domestic and export markets. A short description of the import market is included. Comparisons are made with the previous year. Export volumes of light crude oil in 1988 increased by 13% to average 50,200 m 3 /d. Export volumes of heavy crude also increased by ca 13% to 62,600 m 3 /d. 15 figs., 2 tabs

KLF4 Nuclear Export Requires ERK Activation and Initiates Exit from Naive Pluripotency.

Cooperative action of a transcription factor complex containing OCT4, SOX2, NANOG, and KLF4 maintains the naive pluripotent state; however, less is known about the mechanisms that disrupt this complex, initiating exit from pluripotency. We show that, as embryonic stem cells (ESCs) exit pluripotency, KLF4 protein is exported from the nucleus causing rapid decline in Nanog and Klf4 transcription; as a result, KLF4 is the first pluripotency transcription factor removed from transcription-associated complexes during differentiation. KLF4 nuclear export requires ERK activation, and phosphorylation of KLF4 by ERK initiates interaction of KLF4 with nuclear export factor XPO1, leading to KLF4 export. Mutation of the ERK phosphorylation site in KLF4 (S132) blocks KLF4 nuclear export, the decline in Nanog, Klf4, and Sox2 mRNA, and differentiation. These findings demonstrate that relocalization of KLF4 to the cytoplasm is a critical first step in exit from the naive pluripotent state and initiation of ESC differentiation.

Quebec's electricity exports

International Nuclear Information System (INIS)

Averyt, W.F.

1992-01-01

In 1987 Hydro-Quebec exported over 16 TWh to New England and New York and it plans to export 3,500 MW of firm power, not interruptible, by the early 2000s. It estimates that the northeast US market has an additional potential of 9,000 MW. The export market has become more difficult than anticipated. The federal/state regulatory framework for electricity generation was changing - it encouraged small scale generation, cogeneration and conservation which decreased demand. Demand for power imports has also been influenced by pricing judgements and avoided costs. Environmental concerns and Native protest have become increasingly important factors affecting future export sales and hence the proposed James Bay developments. Regulatory changes affecting supply and pricing, concerns about continental impacts, about further development of electrical sources together with Native requirements will further complicate the Quebec-US electricity trade.

A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1988 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 32,000 m 3 /d in 1988, up 44% from 1987 levels. Each product except aviation fuel registered increases in export volumes, which reached the highest total volume of the decade. The main reason for the large increase was the first full year of production from the export-directed refinery at Come By Chance, Newfoundland. Export prices for light petroleum products stayed relatively close to USA spot prices. The heavy fuel oil price was mostly above the USA east coast spot price during 1988. Attractive prices on the USA east coast resulted in a few cargoes of middle distillate and motor gasoline shipped from British Columbia. Petroleum products imports came from 12 countries; Quebec had the largest volume of imports in 1988. The USA remained Canada's largest trading partner in petroleum products. Western exporters view the Far East as an ongoing important market. The top single exporter in Canada was Newfoundland Processing, with 32% of the total export volume. 12 figs., 3 tabs

Endoplasmic Reticulum Stress and Obesity.

Science.gov (United States)

Yilmaz, Erkan

2017-01-01

In recent years, the world has seen an alarming increase in obesity and closely associated with insulin resistance which is a state of low-grade inflammation, the latter characterized by elevated levels of proinflammatory cytokines in blood and tissues. A shift in energy balance alters systemic metabolic regulation and the important role that chronic inflammation, endoplasmic reticulum (ER) dysfunction, and activation of the unfolded protein response (UPR) play in this process.Why obesity is so closely associated with insulin resistance and inflammation is not understood well. This suggests that there are probably other causes for obesity-related insulin resistance and inflammation. One of these appears to be endoplasmic reticulum (ER) stress.The ER is a vast membranous network responsible for the trafficking of a wide range of proteins and plays a central role in integrating multiple metabolic signals critical in cellular homeostasis. Conditions that may trigger unfolded protein response activation include increased protein synthesis, the presence of mutant or misfolded proteins, inhibition of protein glycosylation, imbalance of ER calcium levels, glucose and energy deprivation, hypoxia, pathogens or pathogen-associated components and toxins. Thus, characterizing the mechanisms contributing to obesity and identifying potential targets for its prevention and treatment will have a great impact on the control of associated conditions, particularly T2D.

Canada's reactor exports

International Nuclear Information System (INIS)

Morrison, R.W.

1981-01-01

A brief sketch of the development of Canada's nuclear exports is presented and some of the factors which influence the ability to export reactors have been identified. The potential market for CANDUs is small and will develop slowly. The competition will be tough. There are few good prospects for immediate export orders in the next two or three years. Nonetheless there are reasonable opportunities for CANDU exports, especially in the mid-to-late 1980s. Such sales could be of great benefit to Canada and could do much to sustain the domestic nuclear industry. Apart from its excellent economic and technical performance, the main attraction of the CANDU seems to be the autonomy it confers on purchasing countries, the effectiveness with which the associated technology can be transferred, and the diversification it offers to countries which wish to reduce their dependence on the major industrial suppliers. Each sales opportunity is unique, and marketing strategy will have to be tailored to the customer's needs. Over the next decade, the factors susceptible to Canadian government action which are most likely to influence CANDU exports will be the political commitment of the government to those reactor exports, the performance established by the four 600 MWe CANDUs now nearing completion, the continuing successful operation of the nuclear program in Ontario, and the co-ordination of the different components of Canada's nuclear program (AECL, nuclear industry, utilities, and government) in putting forth a coherent marketing effort and following through with effective project management

Sarcoplasmic reticulum function in slow- and fast-twitch skeletal muscles from mdx mice.

Science.gov (United States)

Divet, Alexandra; Huchet-Cadiou, Corinne

2002-08-01

The aim of the present study was to establish whether alterations in sarcoplasmic reticulum function are involved in the abnormal Ca(2+) homeostasis of skeletal muscle in mice with muscular dystrophy ( mdx). The properties of the sarcoplasmic reticulum and contractile proteins of fast- and slow-twitch muscles were therefore investigated in chemically skinned fibres isolated from the extensor digitorum longus (EDL) and soleus muscles of normal (C57BL/10) and mdx mice at 4 and 11 weeks of development. Sarcoplasmic reticulum Ca(2+) uptake, estimated by the Ca(2+) release following exposure to caffeine, was significantly slower in mdx mice, while the maximal Ca(2+) quantity did not differ in either type of skeletal muscle at either stage of development. In 4-week-old mice spontaneous sarcoplasmic reticulum Ca(2+) leakage was observed in EDL and soleus fibres and this was more pronounced in mdx mice. In addition, the maximal Ca(2+)-activated tension was smaller in mdx than in normal fibres, while the Ca(2+) sensitivity of the contractile apparatus was not significantly different. These results indicate that mdx hindlimb muscles are affected differently by the disease process and suggest that a reduced ability of the Ca(2+)-ATPase to load Ca(2+) and a leaky sarcoplasmic reticulum membrane may be involved in the altered intracellular Ca(2+) homeostasis.

Hierarchical protein export mechanism of the bacterial flagellar type III protein export apparatus.

Science.gov (United States)

Minamino, Tohru

2018-06-01

The bacterial flagellum is supramolecular motility machinery consisting of the basal body, the hook and the filament. Flagellar proteins are translocated across the cytoplasmic membrane via a type III protein export apparatus, diffuse down the central channel of the growing structure and assemble at the distal end. Flagellar assembly begins with the basal body, followed by the hook and finally the filament. The completion of hook assembly is the most important morphological checkpoint of the sequential flagellar assembly process. When the hook reaches its mature length of about 55 nm in Salmonella enterica, the type III protein export apparatus switches export specificity from proteins required for the structure and assembly of the hook to those responsible for filament assembly, thereby terminating hook assembly and initiating filament assembly. Three flagellar proteins, namely FliK, FlhB and FlhA, are responsible for this substrate specificity switching. Upon completion of the switching event, interactions among FlhA, the cytoplasmic ATPase complex and flagellar type III export chaperones establish the assembly order of the filament at the hook tip. Here, we describe our current understanding of a hierarchical protein export mechanism used in flagellar type III protein export.

Estimating the contribution of strong daily export events to total pollutant export from the United States in summer

While the export of pollutants from the United States exhibits notable variability from day to day and is often considered to be "episodic," the contribution of strong daily export events to total export has not been quantified. We use carbon monoxide (CO) as a tracer of anthropogenic pollutants in the Model of OZone And Related Tracers (MOZART) to estimate this contribution. We first identify the major export pathway from the United States to be through the northeast boundary (24-48°N along 67.5°W and 80-67.5°W along 48°N), and then analyze 15 summers of daily CO export fluxes through this boundary. These daily CO export fluxes have a nearly Gaussian distribution with a mean of 1100 Gg CO day-1 and a standard deviation of 490 Gg CO day-1. To focus on the synoptic variability, we define a "synoptic background" export flux equal to the 15 day moving average export flux and classify strong export days according to their fluxes relative to this background. As expected from Gaussian statistics, 16% of summer days are "strong export days," classified as those days when the CO export flux exceeds the synoptic background by one standard deviation or more. Strong export days contributes 25% to the total export, a value determined by the relative standard deviation of the CO flux distribution. Regressing the anomalies of the CO export flux through the northeast U.S. boundary relative to the synoptic background on the daily anomalies in the surface pressure field (also relative to a 15 day running mean) suggests that strong daily export fluxes are correlated with passages of midlatitude cyclones over the Gulf of Saint Lawrence. The associated cyclonic circulation and Warm Conveyor Belts (WCBs) that lift surface pollutants over the northeastern United States have been shown previously to be associated with long-range transport events. Comparison with observations from the 2004 INTEX-NA field campaign confirms that our model captures the observed enhancements in CO outflow

Endoplasmic reticulum stress in wake-active neurons progresses with aging.

2011-08-01

Fragmentation of wakefulness and sleep are expected outcomes of advanced aging. We hypothesize that wake neurons develop endoplasmic reticulum dyshomeostasis with aging, in parallel with impaired wakefulness. In this series of experiments, we sought to more fully characterize age-related changes in wakefulness and then, in relevant wake neuronal populations, explore functionality and endoplasmic reticulum homeostasis. We report that old mice show greater sleep/wake transitions in the active period with markedly shortened wake periods, shortened latencies to sleep, and less wake time in the subjective day in response to a novel social encounter. Consistent with sleep/wake instability and reduced social encounter wakefulness, orexinergic and noradrenergic wake neurons in aged mice show reduced c-fos response to wakefulness and endoplasmic reticulum dyshomeostasis with increased nuclear translocation of CHOP and GADD34. We have identified an age-related unfolded protein response injury to and dysfunction of wake neurons. It is anticipated that these changes contribute to sleep/wake fragmentation and cognitive impairment in aging. © 2011 The Authors.

Indonesian coal export potential

International Nuclear Information System (INIS)

Millsteed, Ch.; Jolly, L.; Stuart, R.

1993-01-01

Indonesia's coal mining sector is expanding rapidly. Much of the increase in coal production since the mid-1980s has been exported. Indonesian coal mining companies have large expansion programs and continuing strong export growth is projected for the remainder of the 1990s. The low mining costs of indonesian coal, together with proximity to Asian markets, mean that Indonesia is well placed to compete strongly with other thermal coal exporters and win market share in the large and expanding thermal coal market in Asia. However, there is significant uncertainty about the likely future level of Indonesia's exportable surplus of coal. The government's planned expansion in coal fired power generation could constrain export growth, while the ability of producers to meet projected output levels is uncertain. The purpose in this article is to review coal supply and demand developments in Indonesia and, taking account of the key determining factors, to estimate the level of coal exports from Indonesia to the year 2000. This time frame has been chosen because all currently committed mine developments are expected to be on stream by 2000 and because it is difficult to project domestic demand for coal beyond that year. 29 refs., 8 tabs., 7 figs

Nuclear export controls - Closing the gaps

International Nuclear Information System (INIS)

Schmidt, Fritz W.

2005-01-01

Concerns over a nuclear 'black market' have focused international attention on the effectiveness of nuclear export controls. IAEA Director General Mohamed ElBaradei has stated that the emergence of a multinational illicit network demonstrated the inadequacy of the present export control system, that international cooperation on export controls lay on informal arrangements that were not only not binding but also limited in membership, and that export control information was not systematically shared with the IAEA. This criticism, often heard on the political level, does not really do justice to the work of export control groups. The emergence of a multinational illicit network does not necessarily prove failures in export control systems. Criminal activities, by definition, try to circumvent existing rules and regulations, or they exploit the absence of such rules on State level. To fight such individual cases is not so much a task of regular export control systems, whose function lies primarily in establishing standards and procedures for export controls on State level, but rather the task for intelligence services and their international cooperation. The basis of the export control regime is the Nuclear Non-Proliferation Treaty (NPT). Export controls can - and do - play an important role in fostering this universality goal by demanding the implementation of internationally agreed security standards in recipient countries before export licenses are granted. Drawn from the deliberations in the NPT conferences, the current standards to be demanded as conditions of supply are the following: Safeguards, Physical Protection, National export control provisions. According to the NPT system, export controls require IAEA verification in the recipient country. In addition, export controls enable States to provide information to the IAEA on exports and imports as required by the Additional Protocol. The 2005 NPT Review Conference will be an opportunity to review developments

According to export of UAE commercial reactor and JRTR(Jordan Research and Training Reactor) in 2009, Korea's international prestige has enhanced and it has been more important for researcher in charge of export control to understand and carry out duties on export control by obeying Nuclear Suppliers Group(NSG) Guidelines. Currently, the NSG tries to prevent the proliferation of nuclear weapons by harmonising export control systems of participating countries in relation to trade with nuclear commodities and nuclear-related dual-use materials, equipment, software and technology. In addition, through the implementation of two sets of Guidelines for nuclear exports and nuclear-related exports, the NSG aims to ensure that nuclear trade for peaceful purposes does not contribute to the proliferation of nuclear weapons or other nuclear explosive devices, and that international trade and cooperation in the nuclear field is not hindered unjustly in the process. However, there is still not a little confusion of export businesses owing to lack of understanding of nuclear items in Korea. Therefore, by correctly understanding export control systems, permits and licenses, ITT and persistingly communicating with export businesses, Researchers in charge of export control are able to eliminate confusion of production businesses regarding export and establish a export control culture

RNA Export through the NPC in Eukaryotes.

Science.gov (United States)

Okamura, Masumi; Inose, Haruko; Masuda, Seiji

2015-03-20

In eukaryotic cells, RNAs are transcribed in the nucleus and exported to the cytoplasm through the nuclear pore complex. The RNA molecules that are exported from the nucleus into the cytoplasm include messenger RNAs (mRNAs), ribosomal RNAs (rRNAs), transfer RNAs (tRNAs), small nuclear RNAs (snRNAs), micro RNAs (miRNAs), and viral mRNAs. Each RNA is transported by a specific nuclear export receptor. It is believed that most of the mRNAs are exported by Nxf1 (Mex67 in yeast), whereas rRNAs, snRNAs, and a certain subset of mRNAs are exported in a Crm1/Xpo1-dependent manner. tRNAs and miRNAs are exported by Xpot and Xpo5. However, multiple export receptors are involved in the export of some RNAs, such as 60S ribosomal subunit. In addition to these export receptors, some adapter proteins are required to export RNAs. The RNA export system of eukaryotic cells is also used by several types of RNA virus that depend on the machineries of the host cell in the nucleus for replication of their genome, therefore this review describes the RNA export system of two representative viruses. We also discuss the NPC anchoring-dependent mRNA export factors that directly recruit specific genes to the NPC.

Quantifying export production in the Southern Ocean: Implications for the Baxs proxy

Hernandez-Sanchez, Maria T.; Mills, Rachel A.; Planquette, HéLèNe; Pancost, Richard D.; Hepburn, Laura; Salter, Ian; Fitzgeorge-Balfour, Tania

2011-12-01

The water column and sedimentary Baxs distribution around the Crozet Plateau is used to decipher the controls and timing of barite formation and to evaluate how export production signals are recorded in sediments underlying a region of natural Fe fertilization within the Fe limited Southern Ocean. Export production estimated from preserved, vertical sedimentary Baxs accumulation rates are compared with published export fluxes assessed from an integrated study of the biological carbon pump to determine the validity of Baxs as a quantitative proxy under different Fe supply conditions typical of the Southern Ocean. Detailed assessment of the geochemical partitioning of Ba in sediments and the lithogenic end-member allows appropriate correction of the bulk Ba content and determination of the Baxs content of sediments and suspended particles. The upper water column distribution of Baxs is extremely heterogeneous spatially and temporally. Organic carbon/Baxs ratios in deep traps from the Fe fertilized region are similar to other oceanic settings allowing quantification of the inferred carbon export based on established algorithms. There appears to be some decoupling of POC and Ba export in the Fe limited region south of the Plateau. The export production across the Crozet Plateau inferred from the Baxs sedimentary proxy indicates that the Fe fertilized area to the north of the Plateau experiences enhanced export relative to equivalent Southern Ocean settings throughout the Holocene and that this influence may also have impacted the site to the south for significant periods. This interpretation is corroborated by alternative productivity proxies (opal accumulation, 231Paxs/230Thxs). Baxs can be used to quantify export production in complex settings such as naturally Fe-fertilized (volcanoclastic) areas, providing appropriate lithogenic correction is undertaken, and sediment focusing is corrected for along with evaluation of barite preservation.

Coal exports still growing

1998-01-01

It is shown that the swings and roundabouts of the Asian economic shake out and Australian dollar devaluation are starting to work their way through the Australian export coal market. Perhaps somewhat surprisingly, at this stage the results are not proving to be as bad as were at first predicted by some market watchers. Export revenue and tonnages are up 12% for the year to July 98. Coal exports totaling $9.5 billion left Australia's shores in the 12 months confirming coal as Australia's single largest export revenue earner. Sales volumes in the present financial year are still increasing, the market being driven by steadily increasing Asian demand for steaming coal from places like Korea, Malaysia, Thailand and the Philippines

NEW APPROACHES TO EXPORT COMPETITIVENESS

Directory of Open Access Journals (Sweden)

Alina Petronela NEGREA

2015-04-01

Full Text Available The economic literature and the political discourse typically look at international competitiveness mainly by the means of export market shares. However, globalisation, production fragmentation and the growing importance of global value chains (GVCs increasingly challenge traditional approaches of export competitiveness and call for a more accurate and disaggregated level of analysis. Due to the growing fragmentation of production, a country exports now include a significant amount of imports of intermediate goods which are part of the export value. In this case, a simple analysis of the evolution of exports can distort the international competitive position of a country. The article suggests a new approach based on the value-added content of international trade measured by means of global value chain analysis.

Cholesterol regulates the endoplasmic reticulum exit of the major membrane protein P0 required for peripheral myelin compaction.

Science.gov (United States)

Saher, Gesine; Quintes, Susanne; Möbius, Wiebke; Wehr, Michael C; Krämer-Albers, Eva-Maria; Brügger, Britta; Nave, Klaus-Armin

2009-05-13

Rapid impulse conduction requires electrical insulation of axons by myelin, a cholesterol-rich extension of the glial cell membrane with a characteristic composition of proteins and lipids. Mutations in several myelin protein genes cause endoplasmic reticulum (ER) retention and disease, presumably attributable to failure of misfolded proteins to pass the ER quality control. Because many myelin proteins partition into cholesterol-rich membrane rafts, their interaction with cholesterol could potentially be part of the ER quality control system. Here, we provide in vitro and in vivo evidence that the major peripheral myelin protein P0 requires cholesterol for exiting the ER and reaching the myelin compartment. Cholesterol dependency of P0 trafficking in heterologous cells is mediated by a cholesterol recognition/interaction amino acid consensus (CRAC) motif. Mutant mice lacking cholesterol biosynthesis in Schwann cells suffer from severe hypomyelination with numerous uncompacted myelin stretches. This demonstrates that high-level cholesterol coordinates P0 export with myelin membrane synthesis, which is required for the correct stoichiometry of myelin components and for myelin compaction.

The Chinese Export Displacement Effect Revisited

DEFF Research Database (Denmark)

Elleby, Christian; Yu, Wusheng; Yu, Qian

China’s global export share has increased dramatically over the past decades. This development has prompted an empirical literature on whether Chinese exports displace those originated from elsewhere in various destination markets. In this paper we focus on the growth of China’s exports to the East...... African Community (EAC) countries and show how it has affected exports from the European Union (EU) to the EAC. Our main contribution to the literature on the displacement effect of Chinese exports is a set of total and relative displacement estimates based on different specifications of the gravity model...... where we control for country-year fixed effects so as to avoid the “gold medal mistake” of not accounting for time varying “multilateral resistance”. Our findings do not support the hypothesis that Chinese exports have displaced exports from other countries in general. Nor do they support the hypothesis...

Exploitative Learning by Exporting

DEFF Research Database (Denmark)

Golovko, Elena; Lopes Bento, Cindy; Sofka, Wolfgang

Decisions on entering foreign markets are among the most challenging but also potentially rewarding strategy choices managers can make. In this study, we examine the effect of export entry on the firm investment decisions in two activities associated with learning about new technologies...... and learning about new markets ? R&D investments and marketing investments, in search of novel insights into the content and process underlying learning by exporting. We draw from organizational learning theory for predicting changes in both R&D and marketing investment patterns that accompany firm entry......, it is predominantly the marketing-related investment decisions associated with starting to export that lead to increases in firm productivity. We conclude that learning-by-exporting might be more properly characterized as ?learning about and exploiting new markets? rather than ?learning about new technologies...

Understanding China's renewable energy technology exports

International Nuclear Information System (INIS)

Liu, Jialu; Goldstein, Don

2013-01-01

China became a major player in renewable energy (RE) technology during the 2000s. Chinese solar PV cell and module makers quickly dominated global sales in that industry, while the country's wind turbine producers became poised for significant exports after capturing their rapidly growing home market. In countries like the US, Chinese RE technology strength has been met with claims of excessive governmental support of exports. This study examines to what extent Chinese firms' solar PV and wind technology successes have been enabled by policy supports, and whether those policies appear to have been driven by broader goals versus RE export promotion per se. The evidence suggests that governmental policy toward both wind and solar originated in a push for export-competitive Chinese companies. But the specifics differed substantially due to the particular requirements of building technological capabilities in each: export readiness necessitated substantial support for domestic installation of wind but not solar PV power. The findings also suggest that as the decade of the 2000s progressed, environmental goals played an increasing role alongside export promotion in motivating and shaping Chinese RE technology policies. - Highlights: ► Export policy in the rise of Chinese renewable energy technologies is studied. ► Policy supported wind turbine firms' capabilities via domestic uptake, not exports. ► Pre-2009 solar module exports enjoyed, but did not depend on, export subsidies. ► Renewables development also fit wider technology and environmental policy goals.

BRAZILIAN EXPORTS OF MANUFACTURED WOOD

Directory of Open Access Journals (Sweden)

Rafael de Azevedo Calderon

2010-08-01

Full Text Available The present work deals with the Brazilian exports of sawnwood of non-coniferous, veneer sheets and plywood, from 1961 to 2002. The data regarding the three studied products, sawnwood of non-coniferous, veneer sheets and plywood, were joined through the method of Fisher so that an econometric evaluation of the market of the three products could be carried out. Supply and demand models of the Brazilian exports were specified. The results were satisfactory and they match with the literature. The supply of exports presented a positive answer in relation to the exporter's remuneration, to the production, to the use of the installed capacity (cycles of domestic economical activity and to the tendency, and negative in relation to the internal demand. The demand for the Brazilian exports was influenced positively by the world income, participation index and tendency, and negatively for the relative price. The low elasticity-price of the found demand can have implications in the conservation of the Brazilian forest resources because the exporters can increase the prices, reduce the amounts and still increase the incomes.

Notice to exporters on products prohibited from export (nuclear material, equipment and large nuclear units)

International Nuclear Information System (INIS)

1988-01-01

In order to ensure that the policy to avoid the proliferation of nuclear weapons is complied with, the French Administration applies stricter controls over the export of certain sensitive products, materials and equipment. To this effect, lists of such products, materials and equipment are published in the form of Notices to exporters and periodically revised. This Notice repeals and replaces the previous Notice published in the Official Gazette of 21 January 1986. Annex I contains the list of materials whose export is subject to nuclear non-proliferation controls. Annex II lists the equipment whose export is subject to the same controls. Annex III includes the list of large nuclear units for which an application for prior approval of export must be submitted to the Administrations concerned. (NEA) [fr

Advancing understanding of the fluvial export of organic matter through high-resolution profiling of dissolved organic carbon.

Science.gov (United States)

Waldron, S.; Drew, S.; Gilvear, D.; Murray, H.; Heal, K.

2012-04-01

Quantifying the natural variation (complexity) of a system remains an enduring scientific challenge in better understanding controls on surface water quality. This characterisation is needed in order to reveal controlling processes, such as dilution, and also to identify unusual load profiles. In trying to capture that natural variation we still rely largely on concentration time series (and associated export budgets) generated from manual spot sampling, or from samples collected by autosamplers - approaches which are unlikely to provide the high temporal resolution of parameter concentration required. Now however, advances in sensor technology are helping us address this challenge. Here we present detailed dissolved organic carbon (DOC) export profiles from a small upland river (9.4 km sq.), generated since June 2011 by semi-continuous logging of UV-vis absorption (200-750 nm, every 2.5 nm) every 30 minutes. Observed increases in the concentration of the DOC, [DOC], in freshwaters have prompted significant research to understand the cause and consequences of increased export: higher levels of DOC require additional water purification of potable sources; increased aquatic export may represent a reduction in terrestrial C-soil sequestration; changes in light penetration can affect the heterotrophic / autotrophic balance in surface waters and this has consequences for the food web structure; increased aquatic export may also result in increased carbon dioxide evasion. Additionally, C export is often linked to nutrient export: we have observed statistically significant stoichiometric relationships between DOC and soluble reactive phosphorus (SRP) concentrations, thus understanding better this parameters offers insight into export of other nutrient and the source of material from which these dissolved compounds are produced; this may be particulate. Our Scottish study site is interesting because there are multiple processes that can contribute to DOC and other nutrient

Scale and legacy controls on catchment nutrient export regimes

Science.gov (United States)

Howden, N. J. K.; Burt, T.; Worrall, F.

2017-12-01

Nutrient dynamics in river catchments are complex: water and chemical fluxes are highly variable in low-order streams, but this variability declines as fluxes move through higher-order reaches. This poses a major challenge for process understanding as much effort is focussed on long-term monitoring of the main river channel (a high-order reach), and therefore the data available to support process understanding are predominantly derived from sites where much of the transient response of nutrient export is masked by the effect of averaging over both space and time. This may be further exacerbated at all scales by the accumulation of legacy nutrient sources in soils, aquifers and pore waters, where historical activities have led to nutrient accumulation where the catchment system is transport limited. Therefore it is of particular interest to investigate how the variability of nutrient export changes both with catchment scale (from low to high-order catchment streams) and with the presence of legacy sources, such that the context of infrequent monitoring on high-order streams can be better understood. This is not only a question of characterising nutrient export regimes per se, but also developing a more thorough understanding of how the concepts of scale and legacy may modify the statistical characteristics of observed responses across scales in both space and time. In this paper, we use synthetic data series and develop a model approach to consider how space and timescales combine with impacts of legacy sources to influence observed variability in catchment export. We find that: increasing space and timescales tend to reduce the observed variance in nutrient exports, due to an increase in travel times and greater mixing, and therefore averaging, of sources; increasing the influence of legacy sources inflates the variance, with the level of inflation dictated by the residence time of the respective sources.

Calcium uptake by sarcoplasmic reticulum in the presence of organophosphorus insecticide methyl-parathion

International Nuclear Information System (INIS)

Blasiak, J.

1995-01-01

Using an isotope labelling technique it has been shown that an organophosphorus insecticide methyl parathion (0,0-diethyl 0-4-nitrophenyl phosphorothionate) depressed calcium uptake by sarcoplasmic reticulum isolated from rabbit hind leg muscle. The effect was significant for insecticide concentrations of 50 and 100 μM and was dose-dependent. The insecticide exerted a more pronounced effect on calcium uptake in the presence of ATP in the reticulum environment than in the absence of ATP. The inhibitory action of methyl parathion on Ca 2+ accumulation by sarcoplasmic reticulum can cause a rise in myoplasmic free Ca 2+ , the essential prerequisite for contracture activation. Because methyl parathion, as well as other organophosphorus insecticides, is primarily neurotoxic, evidence of non-specific effect could be important for assessing its environmental safety.

Nitrogen and carbon export from urban areas through removal and export of litterfall

International Nuclear Information System (INIS)

Templer, Pamela H.; Toll, Jonathan W.; Hutyra, Lucy R.; Raciti, Steve M.

2015-01-01

We found that up to 52 ± 17% of residential litterfall carbon (C) and nitrogen (N; 390.6 kg C and 6.5 kg N ha −1  yr −1 ) is exported through yard waste removed from the City of Boston, which is equivalent to more than half of annual N outputs as gas loss (i.e. denitrification) or leaching. Our results show that removing yard waste results in a substantial decrease in N inputs to urban areas, which may offset excess N inputs from atmospheric deposition, fertilizer application and pet waste. However, export of C and N via yard waste removal may create nutrient limitation for some vegetation due to diminished recycling of nutrients. Removal of leaf litter from residential areas disrupts nutrient cycling and residential yard management practices are an important modification to urban biogeochemical cycling, which could contribute to spatial heterogeneity of ecosystems that are either N limited or saturated within urban ecosystems. - Highlights: • We monitored yard waste bags for one complete fall yard waste collection season. • 52% of residential litterfall C and N is exported annually from the City of Boston. • Litterfall export may create nutrient limitation hotspots in urban ecosystems. • C and N export through litterfall collection modifies urban biogeochemical cycling. - Litterfall removal leads to C and N export from urban ecosystems and disrupts nutrient cycling, showing that this activity is an important modification to urban biogeochemical cycling

Nuclear exports. Parliamentary control and confidentiality

International Nuclear Information System (INIS)

Feldmann, Ulrike

2015-01-01

With its decision taken on 21. October 2014 (Az.: 2 BvE 5/11) the Federal Constitutional Court (BVerfG) decided during court proceedings between administrative bodies on the scope and limits of the parliamentary right of information. Even though the proceeding did not deal with nuclear exports but arm exports, foreign trade law, however, does not only designate an export licence obligation for military weapons but also for so called dual-use goods meaning goods, which can be used both for friendly as well as for military purposes. The export of these goods requires according to the so-called Dual-Use Regulation (EG) 428/2009 a licence. Annex I category 0 of the regulation (EG) 428/2009 lists a variety of nuclear materials, plants and equipment items for which this licence applies. In the same manner as arm exports, also exports of nuclear dual-use goods are being discussed in a special cabinet committee, the Federal Security Council (BSR), which shall coordinate cross-departmentally the German security and defence policy under consideration of economic interests and which categorises its results, according to the rules of procedure, as confidential. Also legally not regulated but common ''preliminary enquiries'' at the responsible Federal Ministry or rather Federal Office of Economics and Export Control by companies which plan an export and want to affirm the general approval for their export business prior to conclusion of contract take not only place for arm exports but also for nuclear dual-use goods. The decision by the Federal Constitutional Court can be applied to consultations about the authorisation of nuclear dual-use goods.

Sepsis and septic shock are the common complications in ICUs. Vital organ function disorder contributes a critical role in high mortality after severe sepsis or septic shock, in which endoplasmic reticulum stress plays an important role. Whether anti-endoplasmic reticulum stress with 4-phenylbutyric acid is beneficial to sepsis and the underlying mechanisms are not known. Laboratory investigation. State Key Laboratory of Trauma, Burns and Combined Injury. Sprague-Dawley rats. Using cecal ligation and puncture-induced septic shock rats, lipopolysaccharide-treated vascular smooth muscle cells, and cardiomyocytes, effects of 4-phenylbutyric acid on vital organ function and the relationship with endoplasmic reticulum stress and endoplasmic reticulum stress-mediated inflammation, apoptosis, and oxidative stress were observed. Conventional treatment, including fluid resuscitation, vasopressin, and antibiotic, only slightly improved the hemodynamic variable, such as mean arterial blood pressure and cardiac output, and slightly improved the vital organ function and the animal survival of septic shock rats. Supplementation of 4-phenylbutyric acid (5 mg/kg; anti-endoplasmic reticulum stress), especially administered at early stage, significantly improved the hemodynamic variables, vital organ function, such as liver, renal, and intestinal barrier function, and animal survival in septic shock rats. 4-Phenylbutyric acid application inhibited the endoplasmic reticulum stress and endoplasmic reticulum stress-related proteins, such as CCAAT/enhancer-binding protein homologous protein in vital organs, such as heart and superior mesenteric artery after severe sepsis. Further studies showed that 4-phenylbutyric acid inhibited endoplasmic reticulum stress-mediated cytokine release, apoptosis, and oxidative stress via inhibition of nuclear factor-κB, caspase-3 and caspase-9, and increasing glutathione peroxidase and superoxide dismutase expression, respectively.

Export constraints facing Lesotho-based manufacturing enterprises

Directory of Open Access Journals (Sweden)

Motšelisi C. Mokhethi

2015-07-01

Full Text Available Orientation: Exporting is preferred by many enterprises as the mode of foreign entry as it requires less commitment of organisational resources and offers flexibility of managerial actions. However, enterprises face a number of challenges when attempting to initiate exports or expand their export operations. Research purpose: This study was undertaken to determine the characteristics and composition of export barriers constraining exporting by Lesotho-based manufacturing enterprises. Motivation for the study: Lesotho is faced with low destination diversity and low diversity in export products. Research design, approach and method: Data was collected from 162 Lesotho-based manufacturing enterprises through a self-administered questionnaire. Main findings: In its findings, the study firstly identified international constraints, distribution constraints and financial constraints as factors constraining exporting. Secondly, it was determined that three exporting constraints, all internal to the enterprise and all related to one factor (namely financial constraint hampered exporting. Lastly, the ANOVA results revealed that the perceptions of export constraints differed according to the enterprise characteristics, enterprise size, ownership and type of industry. Contribution/value-add: With the majority of enterprises in this study being identified as micro-enterprises, the government of Lesotho needs to pay particular attention to addressing the export needs of these enterprises in order to enable them to participate in exporting activities − especially considering that they can play a pivotal role in the alleviation of poverty, job creation and economic rejuvenation.

Biological export of radioactive materials from a leaching pond in SE Idaho

International Nuclear Information System (INIS)

Millard, Jere B.

1978-01-01

A radioecological investigation was conducted to quantify biological export of radioactive materials from a test reactor area leaching pond located on the Idaho National Engineering Laboratory site in southeast Idaho. An estimated 42,000 Ci have been discharged to the pond since 1952. Approximately 35 gamma emitting radionuclides are detectable in unfiltered water. Biomass estimates and mean radionuclide concentrations were determined for major pond compartments. A radionuclide inventory of the pond ecosystem was constructed listing totals for radioactivity present in each compartment. Mean concentrations of predominant radionuclides and population census data were used to estimate biologically exported materials. Particular attention was paid to migrant waterfowl, a resident population of barn swallows (Hirundo rustica), and nesting shore birds. Whole body gamma spectra indicated 15 or more detectable fission and activation products associated with swallows and shore birds, and 20 or more for waterfowl. Concentration factors relative to filtered pond water were also calculated. Finally, biologically exported radioactive materials were compared with total amounts present in the pond. (author)

In this paper, we develop a method to estimate markups using plant-level production data. Our approach relies on cost minimizing producers and the existence of at least one variable input of production. The suggested empirical framework relies on the estimation of a production function and provides...... estimates of plant- level markups without specifying how firms compete in the product market. We rely on our method to explore the relationship be- tween markups and export behavior. We find that markups are estimated significantly higher when controlling for unobserved productivity; that exporters charge......, on average, higher markups and that markups increase upon export entry....

ERManI (Endoplasmic Reticulum Class I α-Mannosidase) Is Required for HIV-1 Envelope Glycoprotein Degradation via Endoplasmic Reticulum-associated Protein Degradation Pathway.

Science.gov (United States)

Zhou, Tao; Frabutt, Dylan A; Moremen, Kelley W; Zheng, Yong-Hui

2015-09-04

Previously, we reported that the mitochondrial translocator protein (TSPO) induces HIV-1 envelope (Env) degradation via the endoplasmic reticulum (ER)-associated protein degradation (ERAD) pathway, but the mechanism was not clear. Here we investigated how the four ER-associated glycoside hydrolase family 47 (GH47) α-mannosidases, ERManI, and ER-degradation enhancing α-mannosidase-like (EDEM) proteins 1, 2, and 3, are involved in the Env degradation process. Ectopic expression of these four α-mannosidases uncovers that only ERManI inhibits HIV-1 Env expression in a dose-dependent manner. In addition, genetic knock-out of the ERManI gene MAN1B1 using CRISPR/Cas9 technology disrupts the TSPO-mediated Env degradation. Biochemical studies show that HIV-1 Env interacts with ERManI, and between the ERManI cytoplasmic, transmembrane, lumenal stem, and lumenal catalytic domains, the catalytic domain plays a critical role in the Env-ERManI interaction. In addition, functional studies show that inactivation of the catalytic sites by site-directed mutagenesis disrupts the ERManI activity. These studies identify ERManI as a critical GH47 α-mannosidase in the ER-associated protein degradation pathway that initiates the Env degradation and suggests that its catalytic domain and enzymatic activity play an important role in this process. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

1993-06-01

Electricity exports from Hydro-Quebec to utilities in the USA significantly affects the economy and environment of Quebec. These exports may be arranged under interconnection agreements to sell excess capacity and production during off-peak periods or under firm sales contracts. Hydro-Quebec exports could also replace power plants that would otherwise be needed in the USA. The economic environment for Hydro-Quebec exports to the USA is reviewed along with the regulatory environment applicable to international trade (General Agreement on Tariffs and Trade, Canada-USA Free Trade Agreement, North American Free Trade Agreement), Quebec (Canadian federal and provincial law), and the USA (federal and state law). A jurisdictional analysis of power export contracts is then presented, citing examples of contracts already signed by Hydro-Quebec with utilities in New York and New England. Contract law and contract provisions are discussed, including common clauses and particular clauses. Suggestions are made for new clauses that would improve the electricity trade. 215 refs., 13 figs., 3 tabs

Export Failure and its Consequences: Theory and Evidence

OpenAIRE

Mora, Jesse

2015-01-01

The purpose of this dissertation is to argue that exporting is a risky endeavor and that there are consequences to export failure. Exporters pay high fixed costs to enter foreign markets, yet the majority will not export beyond one year. What happens to these exporters after they fail abroad? For these firms, exporting likely resulted in heavy profit losses. Despite this, trade literature often views exporting as a harmless exercise based on a simple cost-benefit analysis of foreign profits. ...

Export controls on high technology

Energy Technology Data Exchange (ETDEWEB)

Frank, N.K.

1987-01-01

A overview of the Export Administration Act of 1979 and subsequent regulations and amendments focuses on how licensing requirements and restrictions against boycott affect high technology exports. The purpose of these controls is to limit the export of technology with possible military applications, as well as to advance US foreign policy and protect the economy without imposing too great a restriction on the principles of free trade. Thus, the act encompasses political, economic, and security goals. Problems of predictability arise when embargoes or other controls are imposed for political or foreign policy reasons without regard to economic impacts. Amendments have attempted to streamline the exporting process, particularly in the area of computer and software licensing.

Estimation of the Impacts of Non-Oil Traditional and NonTraditional Export Sectors on Non-Oil Export of Azerbaijan

Directory of Open Access Journals (Sweden)

Nicat Hagverdiyev

2016-12-01

Full Text Available The significant share of oil sector of the Azerbaijan export portfolio necessitates promotion of non-oil exports. This study analyzes weather the commodities which contain the main share (more than 70% in non-oil export are traditional or non-traditional areas, using the so-called Commodity-specific cumulative export experience function, for the 1995-2015 time frame. Then, the impact of traditional and non-traditional exports on non-oil GDP investigated employing econometric model. The results of the study based on 16 non-oil commodities show that cotton, tobacco, and production of mechanic devices are traditional sectors in non-oil export. The estimation results of the model indicate that both, traditional and non-traditional non-oil export sectors have economically and statistically significant impact on non-oil GDP.

Iran, a gas exporter?

International Nuclear Information System (INIS)

Therme, C.

2008-01-01

The development of the gas sector has not allowed, up to now, Iran to become one of the main gas actors, whether it is on the regional or international market. This under-development of the gas sector finds expression, each winter, through the Iranian incapability to satisfy its domestic demand as well as its exportation commitments to Turkey or Armenia. In this study, the author tries to examine the origins of Iranian difficulties to increase its gas production and to abide by its commitments to export gas to other countries. The possibility of gas exportation from Iran to the European Union is also discussed

Complete Element Abundances of Nine Stars in the r-process Galaxy Reticulum II

Science.gov (United States)

Ji, Alexander P.; Frebel, Anna; Simon, Joshua D.; Chiti, Anirudh

2016-10-01

We present chemical abundances derived from high-resolution Magellan/Magellan Inamori Kyocera Echelle spectra of the nine brightest known red giant members of the ultra-faint dwarf galaxy Reticulum II (Ret II). These stars span the full metallicity range of Ret II (-3.5 contaminated known r-process pattern. The abundances of lighter elements up to the iron peak are otherwise similar to abundances of stars in the halo and in other ultra-faint dwarf galaxies. However, the scatter in abundance ratios is large enough to suggest that inhomogeneous metal mixing is required to explain the chemical evolution of this galaxy. The presence of low amounts of neutron-capture elements in other ultra-faint dwarf galaxies may imply the existence of additional r-process sites besides the source of r-process elements in Ret II. Galaxies like Ret II may be the original birth sites of r-process enhanced stars now found in the halo. This paper includes data gathered with the 6.5 m Magellan Telescopes located at Las Campanas Observatory, Chile.

A Study on Improvement of Export Control law's understanding for nuclear control items' exporters in Rep. of Korea

Energy Technology Data Exchange (ETDEWEB)

Lim, Dong Hyuk; Choi, Sun Do; Yang, Seung Hyo [Korea Institute of Nuclear Nonproliferation and Control, Daejeon (Korea, Republic of)

2011-10-15

According to export of UAE commercial reactor and JRTR(Jordan Research and Training Reactor) in 2009, Korea's international prestige has enhanced and it has been more important for researcher in charge of export control to understand and carry out duties on export control by obeying Nuclear Suppliers Group(NSG) Guidelines. Currently, the NSG tries to prevent the proliferation of nuclear weapons by harmonising export control systems of participating countries in relation to trade with nuclear commodities and nuclear-related dual-use materials, equipment, software and technology. In addition, through the implementation of two sets of Guidelines for nuclear exports and nuclear-related exports, the NSG aims to ensure that nuclear trade for peaceful purposes does not contribute to the proliferation of nuclear weapons or other nuclear explosive devices, and that international trade and cooperation in the nuclear field is not hindered unjustly in the process. However, there is still not a little confusion of export businesses owing to lack of understanding of nuclear items in Korea. Therefore, by correctly understanding export control systems, permits and licenses, ITT and persistingly communicating with export businesses, Researchers in charge of export control are able to eliminate confusion of production businesses regarding export and establish a export control culture

Catalytically Active Guanylyl Cyclase B Requires Endoplasmic Reticulum-mediated Glycosylation, and Mutations That Inhibit This Process Cause Dwarfism.

2016-05-20

C-type natriuretic peptide activation of guanylyl cyclase B (GC-B), also known as natriuretic peptide receptor B or NPR2, stimulates long bone growth, and missense mutations in GC-B cause dwarfism. Four such mutants (L658F, Y708C, R776W, and G959A) bound (125)I-C-type natriuretic peptide on the surface of cells but failed to synthesize cGMP in membrane GC assays. Immunofluorescence microscopy also indicated that the mutant receptors were on the cell surface. All mutant proteins were dephosphorylated and incompletely glycosylated, but dephosphorylation did not explain the inactivation because the mutations inactivated a "constitutively phosphorylated" enzyme. Tunicamycin inhibition of glycosylation in the endoplasmic reticulum or mutation of the Asn-24 glycosylation site decreased GC activity, but neither inhibition of glycosylation in the Golgi by N-acetylglucosaminyltransferase I gene inactivation nor PNGase F deglycosylation of fully processed GC-B reduced GC activity. We conclude that endoplasmic reticulum-mediated glycosylation is required for the formation of an active catalytic, but not ligand-binding domain, and that mutations that inhibit this process cause dwarfism. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

Exports of petroleum products, 1990

International Nuclear Information System (INIS)

1991-04-01

A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1990 calendar year. Exports of the above petroleum products averaged 34,000 m 3 /d in 1990, up 12% from 1989 levels. The increase reflects increased output from the Come By Chance refinery in Newfoundland. Motor gasoline exports increased 35% to 10,500 m 3 /d, reflecting refinery upgrading in eastern Canada. Export prices were generally in line with spot product prices in the USA. Spot prices rose sharply following the Kuwait crisis in August 1990 but fell again in November. The spot price for jet fuel rose more dramatically in that period than for other products, reflecting increased military demand. In winter 1989/90 and during the Kuwait conflict, the export price of heating oil tended to track the USA spot price. Petroleum products imports in 1990 were 18,500 m 3 /d, compared to 21,900 m 3 /d in 1988. Imports were lower partially as a result of higher crude runs in Quebec and a Quebec refinery expansion. Imports of heavy fuel oil in eastern Canada continued to be strong in comparison to the mid-1980s. The top single exporter in 1990, as in 1989, was Newfoundland Processing, with a volume of 4,506,400 m 3 . 13 figs., 5 tabs

Exports of petroleum products, 1989

International Nuclear Information System (INIS)

1990-04-01

A summary is presented of exports of motor gasoline, middle distillate, aviation turbine fuel, heavy fuel oil, and partially processed oil from Canada for the 1989 calendar year. A discussion of petroleum product imports is included in order to put exports in the context of the overall trade. Exports of the above petroleum products averaged 30,400 m 3 /d in 1989, down 5% from 1988 levels. Motor gasoline shipments showed the largest decrease, down 1,500 m 3 to 7,700 m 3 /d. Export prices for light petroleum products stayed relatively close to USA spot prices except in June and July 1989, when attractive prices were obtained for shipments from the prairie provinces. The heavy fuel oil export price was similar to the USA east coast spot price in 1989, except in December. Canada's petroleum products imports in 1989 were 21,600 m 3 /d, compared to 18,400 m 3 /d in 1988. Imports of heavy fuel oil in eastern Canada rose 36% in 1989 because of industries switching from electricity and the high demand for thermal power generation. The USA remained Canada's largest trading partner in petroleum products. The top single exporter in 1989, as in 1988, was Newfoundland Processing, with a volume of 3,484,500 m 3 . 24 figs., 4 tabs

Molecular evidence that rough endoplasmic reticulum is the site of calreticulin translation in Petunia pollen tubes growing in vitro.

Science.gov (United States)

Suwińska, Anna; Lenartowski, Robert; Smoliński, Dariusz Jan; Lenartowska, Marta

2015-07-01

In germinating pollen grains and growing pollen tubes, CRT is translated on ER membrane-bound ribosomes in the regions where its activity is required for stabilization of tip-focused Ca (2+) gradient. Pollen tube growth requires coordination of signaling, exocytosis, and actin cytoskeletal organization. Many of these processes are thought to be controlled by finely tuned regulation of cytoplasmic Ca(2+) in discrete regions of the tube cytoplasm. Most notably, a mechanism must function to maintain a steep gradient of Ca(2+) that exists at the tip of growing pollen tube. Several pieces of evidence point to calreticulin (CRT) as a key Ca(2+)-binding/-buffering protein involved in pollen germination and pollen tube growth. We previously hypothesized that in germinating pollen and growing tubes, CRT is translated on the ribosomes associated with endoplasmic reticulum (ER) in the regions where its activity might be required. In this report, we have addressed this idea by identifying the sites where CRT mRNA, CRT protein, 18S rRNA, and rough ER are localized in Petunia pollen tubes. We observed all four components in the germinal aperture of pollen grains and in subapical regions of elongating tubes. These results seem to support our idea that CRT is translated on ER membrane-bound ribosomes during pollen germination and pollen tube growth. In elongated pollen tubes, we found CRT mainly localized in the subapical zone, where ER and Golgi stacks are abundant. In eukaryotic cells, these organelles serve as mobile intracellular stores of easily releasable Ca(2+), which can be buffered by proteins such as CRT. Therefore, we postulate that subapical-localized CRT is involved in pollen tube growth by maintaining the stable tip-focused Ca(2+) gradient and thus modulating local Ca(2+) concentration within the tube cytoplasm.

Effects of ginger extract on smooth muscle activity of sheep reticulum and rumen

Directory of Open Access Journals (Sweden)

Amin Mamaghani

2013-06-01

Full Text Available Reticulorumen hypomotility leads to the impaired physiologic functions of the digestive tract. Prokinetic action of ginger has been demonstrated in the laboratory animals and human. The aim of this study was to evaluate the effect of hydroalcoholic extract of ginger on contraction and motility of reticulum and rumen of ruminants. Collected samples of reticulum and rumen from eight sheep were investigated in vitro. The extract at the concentration of 0.1 and 1.0 mg L-1 had no effect on any preparations. Contraction of reticulum and rumen preparations was occurred at 10.0 and 100 mg L-1 concentrations (p < 0.05. Concentration of 1000 mg L-1 caused a relaxation in preparations contracted with 10.0 and 100 mg L-1. Likewise, the concentration of 1000 mg L-1 significantly (p < 0.05 inhibited ACh-induced contraction in both tissues. Six sheep were involved in electromyographic study. Administration of 40 mg kg-1 of the extract increased the overall frequency of contractions of the reticulum and rumen at the subsequent three days with the prominent increase at the second day (p < 0.05. Results of in vitro study indicated that hydroalcoholic extract of ginger contained spasmogenic and spasmolytic constituents. The results in vivo study represented evidences that the extract may have stimulant effect on reticulorumen motility in 40 mg kg-1 concentration.

The Export Promoting Effect of Emigration

DEFF Research Database (Denmark)

Hiller, Sanne

The theoretical claim that ethnic networks encourage trade has found broad empirical support in the literature on migration, business networks and international trade. Ethnic networks matter for the exporting firm, as they exhibit the potential to lower fixed and variable cost of exporting....... This paper provides a first attempt to identify the export-promoting effect of emigration on the firm level. Using detailed Danish firm-level data, we can parsimoniously control for export determinants other than emigration, unobserved heterogeneity at the firm level, as well as for self-selection of firms...... into exporting. Additionally accounting for taste similarity between Denmark and its trade partners, our findings suggest a positive effect of emigration on Danish manufacturing trade within Europe, thereby corroborating preceding studies on aggregate data. Nevertheless, as a novel insight, our analysis reveals...

Endoplasmic reticulum stress and diabetic retinopathy

Full Text Available Toshiyuki Oshitari1,2, Natsuyo Hata1, Shuichi Yamamoto11Department of Ophthalmology and Visual Science, Chiba University Graduate School of Medicine, Chiba City, Chiba, Japan; 2Department of Ophthalmology, Kimitsu Central Hospital, Kisarazu City, Chiba, JapanAbstract: Endoplasmic reticulum (ER stress is involved in the pathogenesis of several diseases including Alzheimer disease and Parkinson disease. Many recent studies have shown that ER stress is related to the pathogenesis of diabetes mellitus, and with the death of pancreatic β-cells, insulin resistance, and the death of the vascular cells in the retina. Diabetic retinopathy is a major complication of diabetes and results in death of both neural and vascular cells. Because the death of the neurons directly affects visual function, the precise mechanism causing the death of neurons in early diabetic retinopathy must be determined. The ideal therapy for preventing the onset and the progression of diabetic retinopathy would be to treat the factors involved with both the vascular and neuronal abnormalities in diabetic retinopathy. In this review, we present evidence that ER stress is involved in the death of both retinal neurons and vascular cells in diabetic eyes, and thus reducing or blocking ER stress may be a potential therapy for preventing the onset and the progression of diabetic retinopathy.Keywords: endoplasmic reticulum stress, diabetic retinopathy, vascular cell death, neuronal cell death

Dual function of the nuclear export signal of the Borna disease virus nucleoprotein in nuclear export activity and binding to viral phosphoprotein.

Science.gov (United States)

Yanai, Mako; Sakai, Madoka; Makino, Akiko; Tomonaga, Keizo

2017-07-11

Borna disease virus (BoDV), which has a negative-sense, single-stranded RNA genome, causes persistent infection in the cell nucleus. The nuclear export signal (NES) of the viral nucleoprotein (N) consisting of leucine at positions 128 and 131 and isoleucine at positions 133 and 136 overlaps with one of two predicted binding sites for the viral phosphoprotein (P). A previous study demonstrated that higher expression of BoDV-P inhibits nuclear export of N; however, the function of N NES in the interaction with P remains unclear. We examined the subcellular localization, viral polymerase activity, and P-binding ability of BoDV-N NES mutants. We also characterized a recombinant BoDV (rBoDV) harboring an NES mutation of N. BoDV-N with four alanine-substitutions in the leucine and isoleucine residues of the NES impaired its cytoplasmic localization and abolished polymerase activity and P-binding ability. Although an alanine-substitution at position 131 markedly enhanced viral polymerase activity as determined by a minigenome assay, rBoDV harboring this mutation showed expression of viral RNAs and proteins relative to that of wild-type rBoDV. Our results demonstrate that BoDV-N NES has a dual function in BoDV replication, i.e., nuclear export of N and an interaction with P, affecting viral polymerase activity in the nucleus.

Cucumber leaf spot virus (CLSV) is a member of the Aureusvirus genus, family Tombusviridae. The auxiliary replicase of Tombusvirids has been found to localize to endoplasmic reticulum (ER), peroxisomes or mitochondria; however, localization of the auxiliary replicase of aureusviruses has not been determined. We have found that the auxiliary replicase of CLSV (p25) fused to GFP colocalizes with ER and that three predicted transmembrane domains (TMDs) at the N-terminus of p25 are sufficient for targeting, although the second and third TMDs play the most prominent roles. Confocal analysis of CLSV infected 16C plants shows that the ER becomes modified including the formation of punctae at connections between ER tubules and in association with the nucleus. Ultrastructural analysis shows that the cytoplasm contains numerous vesicles which are also found between the perinuclear ER and nuclear membrane. It is proposed that these vesicles correspond to modified ER used as sites for CLSV replication. - Highlights: • The CLSV p25 auxiliary replicase targets the endoplasmic reticulum (ER). • Targeting of CLSV p25 is associated with ER restructuring. • Restructuring of the ER occurs during CLSV infection. • CLSV p25 contains 3 predicted transmembrane domains 2 of which are required for ER targeting. • Vesicles derived from the ER may be sites of CLSV replication.

Export Control in the AREVA Group

International Nuclear Information System (INIS)

Zero, S.

2013-01-01

After the Second World War the nuclear technology was mostly considered inappropriate for the export. It remains strictly regulated today, but the development of the civil applications urged states to facilitate the peaceful uses while establishing a strict control in the domains of the internal security and the nuclear proliferation. AREVA decided to set up an Export Control program applied to all the products and in all the countries where the group operates. AREVA can export products or make transfer of technology considered as sensitive for the non-proliferation and the risks linked to the terrorism. This sensitiveness results from the nature of the products or from the country of destination and in certain cases both of them. AREVA has set up an Export Control program and an interactive e-learning training within the Group to make exports of sensitive products, raw materials and technologies more secure. The subject is rather complex, the regulations are constantly evolving, and becoming familiar with them is necessarily a gradual process, but it must be made in-depth, hence the idea of regular training sessions. The implementation of the Export Control in the AREVA Group declines in four fundamental stages: -) Policy and procedure; -) Appointment of Export Control Officers (ECO); -) Training; and -) Audit and Self Assessment. The training program is composed by the following elements: Ethics (Value Charter) of the Group, Non-proliferation, international regulations and more particularly those that are applicable in Europe (Germany and France) and in the United States. Particular attention is devoted to the Export Control practice in China, Japan and India. (A.C.)

Economic and Financial Evaluation of The Irradiation Facility Unit For Some Egyptian Agricultural Exports

International Nuclear Information System (INIS)

Amin, S.R.A.

2014-01-01

Food irradiation technology strongly enhances quarantine, especially that chemical methods to preserve food and agricultural products are completely banned. The technology of food preservation by irradiation helps increasing Egypt’s agricultural exports to foreign markets as these exports become more competitive due to their long shelf life and decrease of loss. Therefore, food irradiation technology helps avoiding economic loss. The present study aims at conducting a financial analysis and economic evaluation for establishing an irradiation unit for some Egypt’s agricultural exports to enhance their competitiveness and help exporters in marketing them. The study also considers the site location of the unit because of the important role it plays in influencing the project size, production capacity, costs and expected profits. The study consists of four sections namely: Section one: This section includes two chapters. Chapter one presents the theoretical framework of the study. Chapter two displays the literature review. Chapter one includes key concepts and terms of irradiation, purpose of food irradiation, types of irradiation units, application in fruits and vegetables irradiation, radiation doses used in irradiating food and requirements for safety of food irradiation. chapter two reveals the literature review of previous research of the topic showing important results and conclusions made of previous studies and research, studies are divided into two parts, part one relate to agricultural exports, as part two links food irradiation technology. Section Two: This section presents a study of irradiating Egypt’s agricultural exports .This section is divided into two chapters; chapter one reveals the economic importance of irradiating agricultural products, and chapter two illustrates different types of irradiation techniques. The results in this section show the advantages of food irradiation technology in terms of marketing, health, environment and cost

Human Capital and Wages in Exporting Firms

This paper studies the link between a firms education level, export performance and wages of its workers. We argue that firms may escape intence competition in international markets by using high skilled workers to differentiate their products. This story is consistent with our empirical results....... Osing a very rich matched worker-firm longitudinal dataset we find that firms with high export intensities pay higher wages. However, an interaction term between export intensity and skill intensity has a positive impact on wages and it absorbs the direct effect of the export intensity. That is, we find...... an export wage premium, but it accrues to workers in firms with high skill intensities.Keywords: Exports, Wages, Human Capital, Rent Sharing, Matched Worker-Firm DataJEL Classification: J30, F10, I20...

Tributyltin induces apoptotic signaling in hepatocytes through pathways involving the endoplasmic reticulum and mitochondria

2007-01-01

Tri-n-butyltin is a widespread environmental toxicant, which accumulates in the liver. This study investigates whether tri-n-butyltin induces pro-apoptotic signaling in rat liver hepatocytes through pathways involving the endoplasmic reticulum and mitochondria. Tri-n-butyltin activated the endoplasmic reticulum pathway of apoptosis, which was demonstrated by the activation of the protease calpain, its translocation to the plasma membrane, followed by cleavage of the calpain substrates, cytoskeletal protein vinculin, and caspase-12. Caspase-12 is localized to the cytoplasmic side of the endoplasmic reticulum and is involved in apoptosis mediated by the endoplasmic reticulum. Tri-n-butyltin also caused translocation of the pro-apoptotic proteins Bax and Bad from the cytosol to mitochondria, as well as changes in mitochondrial membrane permeability, events which can activate the mitochondrial death pathway. Tri-n-butyltin induced downstream apoptotic events in rat hepatocytes at the nuclear level, detected by chromatin condensation and by confocal microscopy using acridine orange. We investigated whether the tri-n-butyltin-induced pro-apoptotic events in hepatocytes could be linked to perturbation of intracellular calcium homeostasis, using confocal microscopy. Tri-n-butyltin caused changes in intracellular calcium distribution, which were similar to those induced by thapsigargin. Calcium was released from a subcellular compartment, which is likely to be the endoplasmic reticulum, into the cytosol. Cytosolic acidification, which is known to trigger apoptosis, also occurred and involved the Cl - /HCO 3 - exchanger. Pro-apoptotic events in hepatocytes were inhibited by the calcium chelator, Bapta-AM, and by a calpain inhibitor, which suggests that changes in intracellular calcium homeostasis are involved in tri-n-butyltin-induced apoptotic signaling in rat hepatocytes

This article studies systems integrators' export channel pricing management for integrated solutions. We find support from our empirical case study for the notion that a systems integrator's export channel pricing strategy is multidimensional and dependent on international pricing environment and partner characteristics and that export partnerships have unique implications on a systems integrator's pricing process. The results show that giving up pricing control in export channel context may ...

There is a wide range of trade barriers, particularly tariffs, in current and potential coal market. Commonwealth departments in Australia play a crucial role in supporting government industry policies. This article summarises some of more recent activities of the Department of Primary Industries and Energy (DPIE) in facilitating the export of Australian Coals. Coal export facilitation activities are designed to assist the Australian coal industry by directing Commonwealth Government resources towards issues which would be inappropriate or difficult for the industry to address itself

Human Capital and Wages in Exporting Firms

DEFF Research Database (Denmark)

Munch, Jakob Roland; Skaksen, Jan Rose

This paper studies the link between a firms education level, export performance and wages of its workers. We argue that firms may escape intense competition in international markets by using high skilled workers to differentiate their products. This story is consistent with our empirical results....... Using a very rich matched worker-firm longitudinal dataset we find that firms with high export intensities pay higher wages. However, an interaction term between export intensity and skill intensity has a positive impact on wages and it absorbs the direct effect of the export intensity. That is, we find...... an export wage premium, but it accrues to workers in firms with high skill intensities...

Nuclear export controls and nuclear safeguards

International Nuclear Information System (INIS)

Sevini, F.

2013-01-01

The export control of dual use goods has developed since the early seventies to counter nuclear proliferation. The paper provides an overview of dual-use export control issues also in relation with the Additional Protocol to the Comprehensive Safeguards Agreement, which requires States to provide declarations of the export of the controlled items listed in its Annex II, derived from the Nuclear Suppliers Group Trigger list. Recommendations for improvement are proposed. On the EU level, the paper summarises the framework set by the European Council Regulation 428/2009, requiring Member States to impose control on exports, brokering and transit of dual use goods. The Regulation includes the so-called 'EU dual-use control list' integrating the lists of dual-use items defined by the international regimes and requires also the control on intangible technology transfers as foreseen by U.N. Security Council Resolution 1540. ESARDA has recently launched a new sub-Working Group on export control, which raised large interest and may evolve to a full-fledged working group. Export control may provide an opportunity of technical collaboration between ESARDA and INMM. The paper is followed by the slides of the presentation. (author)

Exports and economic growth in Nigeria

Directory of Open Access Journals (Sweden)

Goodly Otto

2016-09-01

Full Text Available Nigeria is an oil dependent economy, over 90 per cent of its exports receipts in recent years flow from petroleum but this sector is currently affected by local challenges, which include insecurity, oil thefts, sabotage and an unfriendly operational environment. These challenges are generating loses for the major producers and encouraging capital flight but amidst this situation, the economy is said to be having an impressive growth. This paradox informed this research. The study was designed to see the nexus between exports and economic growth in Nigeria. Using data from the Central Bank of Nigeria spanning 1980-2011, the study with the aid of OLS regression analysis found a strong relationship between Exports and economic growth in Nigeria. Nigeria will be better served if it diversifies its export base. It must also create structures that lead to better redistribution of export incomes within the local economy.

2006-01-01

Political risk represents an important hidden transaction cost that reduces international trade. This paper investigates the claim that German public export credit guarantees (Hermes guarantees) mitigate this friction to trade flows and hence promote exports. We employ an empirical trade gravity model, where we explicitly control for political risk in the importing country in order to evaluate the effect of export guarantees. The idea behind export promotion through public export credit agenc...

Mechanism for G2 phase-specific nuclear export of the kinetochore protein CENP-F.

Science.gov (United States)

Loftus, Kyle M; Cui, Heying; Coutavas, Elias; King, David S; Ceravolo, Amanda; Pereiras, Dylan; Solmaz, Sozanne R

2017-08-03

Centromere protein F (CENP-F) is a component of the kinetochore and a regulator of cell cycle progression. CENP-F recruits the dynein transport machinery and orchestrates several cell cycle-specific transport events, including transport of the nucleus, mitochondria and chromosomes. A key regulatory step for several of these functions is likely the G2 phase-specific export of CENP-F from the nucleus to the cytosol, where the cytoplasmic dynein transport machinery resides; however, the molecular mechanism of this process is elusive. Here, we have identified 3 phosphorylation sites within the bipartite classical nuclear localization signal (cNLS) of CENP-F. These sites are specific for cyclin-dependent kinase 1 (Cdk1), which is active in G2 phase. Phosphomimetic mutations of these residues strongly diminish the interaction of the CENP-F cNLS with its nuclear transport receptor karyopherin α. These mutations also diminish nuclear localization of the CENP-F cNLS in cells. Notably, the cNLS is phosphorylated in the -1 position, which is important to orient the adjacent major motif for binding into its pocket on karyopherin α. We propose that localization of CENP-F is regulated by a cNLS, and a nuclear export pathway, resulting in nuclear localization during most of interphase. In G2 phase, the cNLS is weakened by phosphorylation through Cdk1, likely resulting in nuclear export of CENP-F via the still active nuclear export pathway. Once CENP-F resides in the cytosol, it can engage in pathways that are important for cell cycle progression, kinetochore assembly and the faithful segregation of chromosomes into daughter cells.

Sodium Butyrate Induces Endoplasmic Reticulum Stress and Autophagy in Colorectal Cells: Implications for Apoptosis.

Directory of Open Access Journals (Sweden)

Jintao Zhang

Full Text Available Butyrate, a short-chain fatty acid derived from dietary fiber, inhibits proliferation and induces cell death in colorectal cancer cells. However, clinical trials have shown mixed results regarding the anti-tumor activities of butyrate. We have previously shown that sodium butyrate increases endoplasmic reticulum stress by altering intracellular calcium levels, a well-known autophagy trigger. Here, we investigated whether sodium butyrate-induced endoplasmic reticulum stress mediated autophagy, and whether there was crosstalk between autophagy and the sodium butyrate-induced apoptotic response in human colorectal cancer cells.Human colorectal cancer cell lines (HCT-116 and HT-29 were treated with sodium butyrate at concentrations ranging from 0.5-5mM. Cell proliferation was assessed using MTT tetrazolium salt formation. Autophagy induction was confirmed through a combination of Western blotting for associated proteins, acridine orange staining for acidic vesicles, detection of autolysosomes (MDC staining, and electron microscopy. Apoptosis was quantified by flow cytometry using standard annexinV/propidium iodide staining and by assessing PARP-1 cleavage by Western blot.Sodium butyrate suppressed colorectal cancer cell proliferation, induced autophagy, and resulted in apoptotic cell death. The induction of autophagy was supported by the accumulation of acidic vesicular organelles and autolysosomes, and the expression of autophagy-associated proteins, including microtubule-associated protein II light chain 3 (LC3-II, beclin-1, and autophagocytosis-associated protein (Atg3. The autophagy inhibitors 3-methyladenine (3-MA and chloroquine inhibited sodium butyrate induced autophagy. Furthermore, sodium butyrate treatment markedly enhanced the expression of endoplasmic reticulum stress-associated proteins, including BIP, CHOP, PDI, and IRE-1a. When endoplasmic reticulum stress was inhibited by pharmacological (cycloheximide and mithramycin and genetic

Scheme to reward microgenerators exporting excess electricity

International Nuclear Information System (INIS)

2007-01-01

Many suppliers are offering tariffs for export. However, many of the tariffs on offer deliver a value that is higher than the underlying commercial value of the electricity to the supplier. In most cases suppliers do not currently register the export within the industry's settlement arrangements and so gain no value from the export they have purchased. It is clear from this that the current situation is unlikely to be sustainable and suppliers will not be able to offer significant payment for a product that has little commercial value to them when the numbers of exporting microgenerators increases. Initiatives to simplify and streamline the existing trading arrangements should be progressed; this should include simplification of processes for registering new export customers and improvements in the provision of new export meters. Suppliers should initiate the change management procedures required to progress Option 1 (allowing suppliers to register a customer's export and import under a single registration (a single MPAN)) through the industry's normal change management procedures. Ofgem should ensure that its review of the Structure of Distribution charges includes the treatment of DUoS charges for customers with microgeneration and ensure that they properly reflect the benefits of microgeneration. Any changes that are progressed should not prevent the subsequent introduction of 'smart meters' that could process both import and export electricity data. Ofgem should ensure that the cost effectiveness of including both an import and export capability in all new metering systems is assessed as part of the metering innovation agenda. Suppliers should make the prices they are offering for export more widely available in a simple and easy to understand form. Government should consider whether additional intervention is required to yield a higher value for exported electricity (or total generation) via mechanisms such as those contemplated under Option 3 (The supplier

Agriculture is the single largest shareholder to GDP an employment to labour force. It has major share in export but unfortunately unable to meet international standards. This study aims to analyze the pattern of Pakistan cotton export, and to explore sector's export potential and opportunities. This new research endeavor with well-tested analytical tools enabled the trade experts and policy makers to explore the answer of lackness for diversification in export, HS-2- digits aggregated data for cotton sub-sectors have been used with latest data from 2004 to 2013 for the panel 39 countries. Revealed comparative advantage (RCA) index and gravity model approach was employed considering country and time specific fixed effect. The RCA index revealed that cotton sub-sectors have comparative advantage in export and there is gradual gain in the competitiveness with time. The opportunity exists in the markets of low, lower-middle and upper middle income countries and countries those have fair trade (low tariff and non-tariff barriers) for cotton export. Greater export potential lies with malaysia, kenya jordan, thailand, mauritius, netherlands norway, Australia and russian federation for export of cotton, however, export potential for cotton has been exhausted with canada, france, india, iran and saudi arabia. The study provide the policy information that countries of Latin america, eastern europe, central asia and northern africa are virgin for export. Therefore, pakistan should penetrate in these markets for export of cotton and other agricultural products. cognizant to new trade theories, pakistan focus on quality to gain maximum trade volume in the markets of high income countries, Pakistan may develop trade agreement with ASEAN, SAFTA, and EU-27 for export of agricultural products.

Role of endoplasmic reticulum stress in the loss of retinal ganglion cells in diabetic retinopathy

Institute of Scientific and Technical Information of China (English)

Liping Yang; Lemeng Wu; Dongmei Wang; Ying Li; Hongliang Dou; Mark OMTso; Zhizhong Ma

2013-01-01

Endoplasmic reticulum stress is closely involved in the early stage of diabetic retinopathy. In the present study, a streptozotocin-induced diabetic animal model was given an intraperitoneal injection of tauroursodeoxycholic acid. Results from immunofluorescent co-localization experiments showed that both caspase-12 protein and c-Jun N-terminal kinase 1 phosphorylation levels significantly in-creased, which was associated with retinal ganglion celldeath in diabetic retinas. The C/ERB ho-mologous protein pathway directly contributed to glial reactivity, and was subsequently responsible for neuronal loss and vascular abnormalities in diabetic retinopathy. Our experimental findings in-dicate that endoplasmic reticulum stress plays an important role in diabetes-induced retinal neu-ronal loss and vascular abnormalities, and that inhibiting the activation of the endoplasmic reticulum stress pathway provides effective protection against diabetic retinopathy.

China's coal export and inspection

International Nuclear Information System (INIS)

Xiaodong Li

1993-01-01

With the development of world's business and trade, coal has become a large part of the import and export goods in the international market. The total amount of coal trade has risen a lot. China is rich in coal resources. According to the estimate made by some experts, the reserve which has been explored recently could be exploited hundreds of years. China's output of raw coal has risen a lot during the past forty years. China coal industry has developed rapidly since the 1980s. It is possible for China to become a big coal export country since it has rich resources and increasing output. The paper suggests four steps which must be taken to expand coal exports in China: improve the level of management and administration of coal mines so as to raise the economic benefit; the follow-up production capacity of the present mines must be enhanced rapidly; step up construction of new large-scale mines; and China's coal washing capacity must be improved speedily since the low capacity has seriously influenced the improvement of coal quality. The paper describes the inspection bureaus and companies that have developed to perform inspection of exports in order to guarantee the quality of export coal

Energy efficiency and exporting: Evidence from firm-level data

International Nuclear Information System (INIS)

Roy, Jayjit; Yasar, Mahmut

2015-01-01

While exporting firms and non-exporters have been compared across several dimensions, empirical comparisons on the basis of environmental performance are relatively few. Moreover, analyzing the environmental implications of firm-level exports is not trivial due to non-random selection into exporting. In this light, we examine the impact of exporting on firms' energy efficiency by resorting to an instrumental variables strategy based on a differencing approach (Pitt and Rosenzweig, 1990). Utilizing data from Indonesia, we find (i) exporting to reduce the use of fuels (relative to electricity) and (ii) concerns over endogeneity of exporting status to be relevant. - Highlights: • We examine the impact of exporting on firms' energy efficiency. • We employ cost share equations, firm-level data from Indonesia, and an instrumental variables strategy. • Exporting is found to reduce the use of fuels (relative to electricity).

It is determined that the key business indicators of the system for diagnostics of enterprise export potential are: the level of enterprises competitiveness in the international (global market; the level of competitiveness of enterprise products; the level of competitiveness of enterprise export products; the level of enterprise resource opportunities; the level of enterprise export performance. Prospects for further research in this direction are to develop a classification (specifically detailed list of objectives of the enterprise diagnostics by the level of detail (element, partial, complex, taking into account diagnostics of export potential of the enterprise as part of diagnostic objective.

Price and Income Elasticities of Russian Exports

Directory of Open Access Journals (Sweden)

Bernardina Algieri

2004-12-01

Full Text Available The paper gauges export demand elasticities for Russia using an Error Correction technique within a cointegration framework. An extended version of the Imperfect Substitutes Model has been implemented to estimate the sensitivity of Russian exports without oil components to price and to Russian and world income. Our results suggest a robust and negative long run cointegration relationship between the real effective exchange rate, defined as the weighted average of the rouble’s exchange rates versus a basket of the three currencies with the largest share in the trade turnover adjusted to incorporate inflation rate differences (the ratio of the domestic price indices to the foreign price indices, and Russian exports. An increase in exports by 24% is caused by a real depreciation by 10%. Furthermore, a 10% growth in world income leads to a 33% rise in exports. Finally, exports drop by 14% whenever a 10% increase in domestic income occurs

Nuclear Export of Pre-Ribosomal Subunits Requires Dbp5, but Not as an RNA-Helicase as for mRNA Export.

Science.gov (United States)

Neumann, Bettina; Wu, Haijia; Hackmann, Alexandra; Krebber, Heike

2016-01-01

The DEAD-box RNA-helicase Dbp5/Rat8 is known for its function in nuclear mRNA export, where it displaces the export receptor Mex67 from the mRNA at the cytoplasmic side of the nuclear pore complex (NPC). Here we show that Dbp5 is also required for the nuclear export of both pre-ribosomal subunits. Yeast temperature-sensitive dbp5 mutants accumulate both ribosomal particles in their nuclei. Furthermore, Dbp5 genetically and physically interacts with known ribosomal transport factors such as Nmd3. Similar to mRNA export we show that also for ribosomal transport Dbp5 is required at the cytoplasmic side of the NPC. However, unlike its role in mRNA export, Dbp5 does not seem to undergo its ATPase cycle for this function, as ATPase-deficient dbp5 mutants that selectively inhibit mRNA export do not affect ribosomal transport. Furthermore, mutants of GLE1, the ATPase stimulating factor of Dbp5, show no major ribosomal export defects. Consequently, while Dbp5 uses its ATPase cycle to displace the export receptor Mex67 from the translocated mRNAs, Mex67 remains bound to ribosomal subunits upon transit to the cytoplasm, where it is detectable on translating ribosomes. Therefore, we propose a model, in which Dbp5 supports ribosomal transport by capturing ribosomal subunits upon their cytoplasmic appearance at the NPC, possibly by binding export factors such as Mex67. Thus, our findings reveal that although different ribonucleoparticles, mRNAs and pre-ribosomal subunits, use shared export factors, they utilize different transport mechanisms.

Full Text Available Analytical approaches to research of export operations depend on the conditions containing in separate external economic contracts with foreign buyers and also on a form of an exit of the Russian supplier of export goods to a foreign market. By means of analytical procedures it is possible to foresee and predict admissible situations which can have an adverse effect on a financial position of the economic subject. The economic entity, the engaged foreign economic activity, has to carry out surely not only the analysis of the current activity, but also the analysis of export operations. In article analytical approaches of carrying out the analysis of export operations are considered, on an example the analysis of export operations in dynamics is submitted, it is recommended to use the formulas allowing to estimate export in dynamics. For the comparative analysis export volume in the comparable prices is estimated. On the commodity groups including and quantitatively and qualitatively commensurable goods, the index of quantitative structure is calculated, the coefficient of delay of delivery of goods in comparison with other periods pays off. Carrying out the analysis allows to determine a tendency of change of export deliveries by export operations for the analyzed period for adoption of administrative decisions.Purpose Definition of the ways and receptions of the analysis applying when carrying out the analysis of export operations.Methodology in article economic-mathematical methods, and also statistical methods of the analysis were used.Results: the most informative parameters showing some aspects of carrying out the analysis of export operations are received.Practical implications it is expedient to apply the received results the economic subjects which are carrying out foreign economic activity, one of which elements are export operations.

Export of nitrogen from catchments: A worldwide analysis

International Nuclear Information System (INIS)

Alvarez-Cobelas, M.; Angeler, D.G.; Sanchez-Carrillo, S.

2008-01-01

This study reviews nitrogen export rates from 946 rivers of the world to determine the influence of quantitative (runoff, rainfall, inhabitant density, catchment area, percentage of land use cover, airborne deposition, fertilizer input) and qualitative (dominant type of forest, occurrence of stagnant waterbodies, dominant land use, occurrence of point sources, runoff type) environmental factors on nitrogen fluxes. All fractions (total, nitrate, ammonia, dissolved organic and particulate organic) of nitrogen export showed a left-skewed distribution, which suggests a relatively pristine condition for most systems. Total nitrogen export showed the highest variability whereas total organic nitrogen export comprised the dominant fraction of export. Nitrogen export rates were only weakly explained by our qualitative and quantitative environmental variables. Our study suggests that the consideration of spatial and temporal scales is important for predicting nitrogen export rates using simple and easy-to-get environmental variables. Regionally based modelling approaches prove more useful than global-scale analyses. - Spatial and temporal scales are important determinants for nitrogen export from catchments and emphasis should be put on regional approaches

The endoplasmic reticulum in plant immunity and cell death.

Science.gov (United States)

Eichmann, Ruth; Schäfer, Patrick

2012-01-01

The endoplasmic reticulum (ER) is a highly dynamic organelle in eukaryotic cells and a major production site of proteins destined for vacuoles, the plasma membrane, or apoplast in plants. At the ER, these secreted proteins undergo multiple processing steps, which are supervised and conducted by the ER quality control system. Notably, processing of secreted proteins can considerably elevate under stress conditions and exceed ER folding capacities. The resulting accumulation of unfolded proteins is defined as ER stress. The efficiency of cells to re-establish proper ER function is crucial for stress adaptation. Besides delivering proteins directly antagonizing and resolving stress conditions, the ER monitors synthesis of immune receptors. This indicates the significance of the ER for the establishment and function of the plant immune system. Recent studies point out the fragility of the entire system and highlight the ER as initiator of programed cell death (PCD) in plants as was reported for vertebrates. This review summarizes current knowledge on the impact of the ER on immune and PCD signaling. Understanding the integration of stress signals by the ER bears a considerable potential to optimize development and to enhance stress resistance of plants.

Besides delivering proteins directly antagonizing and resolving stress conditions, the ER monitors synthesis of immune receptors. This indicates the significance of the ER for the establishment and function of the plant immune system. Recent studies point out the fragility of the entire system and highlight the ER as initiator of programmed cell death (PCD in plants as was reported for vertebrates. This review summarizes current knowledge on the impact of the ER on immune and PCD signalling. Understanding the integration of stress signals by the ER bears a considerable potential to optimize development and to enhance stress resistance of plants.

Nuclear Export of Messenger RNA

Directory of Open Access Journals (Sweden)

Jun Katahira

Full Text Available Transport of messenger RNA (mRNA from the nucleus to the cytoplasm is an essential step of eukaryotic gene expression. In the cell nucleus, a precursor mRNA undergoes a series of processing steps, including capping at the 5' ends, splicing and cleavage/polyadenylation at the 3' ends. During this process, the mRNA associates with a wide variety of proteins, forming a messenger ribonucleoprotein (mRNP particle. Association with factors involved in nuclear export also occurs during transcription and processing, and thus nuclear export is fully integrated into mRNA maturation. The coupling between mRNA maturation and nuclear export is an important mechanism for providing only fully functional and competent mRNA to the cytoplasmic translational machinery, thereby ensuring accuracy and swiftness of gene expression. This review describes the molecular mechanism of nuclear mRNA export mediated by the principal transport factors, including Tap-p15 and the TREX complex.

Danish Energy Agency has previously carried out studies of Danish energy-sector exports. The latest results were published in the report, Energisektorens eksport. Produkter og raadgivning. Danish Energy Agency, September 1998. The present survey is an update of the earlier studies, and includes 1998 exports. As previously, the study, carried out in cooperation with the Confederation of Danish Industries and the Danish Council of Consulting Architects and Engineers, is based on questionnaires sent to relevant companies. In addition, information has been obtained from companies that do not belong to these organisations. On the basis of the answers received, 58 Danish companies exported products to a value of approximately DKK 16,000 million, and 22 consulting firms exported consulting services to a value of approximately DKK 370 million. These exports of approximately DKK 16.5 billion accounted for 5% of all Danish exports in 1998. In comparison with 1996, energy-sector exports have risen by more than 40% in a period in which Danish exports in general have risen by an average of 8%. Energy sector exports provide employment for more than 18,000 persons in Denmark - approximately 17,500 employees in companies that export products, and approximately 600 persons in consulting firms. To this must be added a presumably significantly larger number of persons employed by sub-suppliers to the above companies computed by value, 80% of the exports come from relatively few companies, i.e. 13 companies with products, and five offering consulting services. Energy-sector exports fall within the following product areas: 1) Wind turbines (25%). 2) District heating and combined heat and power (CHP) (21%). 3) Energy savings and control (20%). 4) Oil and natural gas (13%). 5) Electricity plants and power supply (13%). 6) Other (8%). 67% of the exports go to Western Europe, 18% to Asia, 7% to Eastern and Central Europe, and 8% to other parts of the world.

A translocator-specific export signal establishes the translocator-effector secretion hierarchy that is important for type III secretion system function

Science.gov (United States)

Tomalka, Amanda G.; Stopford, Charles M.; Lee, Pei-Chung; Rietsch, Arne

2012-01-01

Summary Type III secretion systems are used by many Gram-negative pathogens to directly deliver effector proteins into the cytoplasm of host cells. To accomplish this, bacteria secrete translocator proteins that form a pore in the host-cell membrane through which the effector proteins are then introduced into the host cell. Evidence from multiple systems indicates that the pore-forming translocator proteins are exported before effectors, but how this secretion hierarchy is established is unclear. Here we used the P. aeruginosa translocator protein PopD as a model to identify its export signals. The amino-terminal secretion signal and chaperone, PcrH, are required for export under all conditions. Two novel signals in PopD, one proximal to the chaperone-binding site and one at the very C-terminus of the protein, are required for export of PopD before effector proteins. These novel export signals establish the translocator-effector secretion hierarchy, which in turn, is critical for the delivery of effectors into host cells. PMID:23121689

Tariffs and Firm-Level Heterogeneous Fixed Export Costs

DEFF Research Database (Denmark)

Schröder, Philipp J.H.; Jørgensen, Jan Guldager

2006-01-01

This paper presents a two country intra-industry trade model with bilateral ad valorem tariffs and fixed export costs that are heterogeneous across firms. In this model not all firms will choose to export. We examine the effects of reciprocal changes in the tariff and the fixed export barrier...... on the number of firms, firm profits, tariff revenue and consumer welfare. We show that both types of trade barriers reduce (increase) the number of exporting (pure domestic) firms. However, the sum of available home and foreign varieties may actually increase for small tariffs. Firm profits fall for both...... the tariff and the fixed export barrier. Tariff revenue falls for an increase in fixed exporting costs whereas we have a Laffer curve effect for the tariff. Finally, we establish that welfare falls with fixed export costs and large tariffs but increases for small tariffs, i.e. there exist a welfare...

Full Text Available The aim of the paper is to investigate the internationalization (particularly exporting of small and medium-sized enterprises (SMEs taking a sample of United Kingdom (UK SMEs for the use in economic policy, academia and management. It focuses on the critical first and less risky step towards internationalization and separates the motivators into home country and host country. The paper investigates 44 specific, high impact, pre-selected exporting motivators from the literature and tests their effect on the firm’s initial export decision and latest (or sequential export decision. Results show that the first exporting choice affects later exporting choices and both are mostly affected by home country-specific, internal, motivators as opposed to host country-specific reactive motivators. In addition regionalization shows an association as European Union membership of the UK showed a relationship to subsequent entry mode choice. The paper’s results are of use to policy-makers and management.

Export regulation

Australia is a major uranium supplier. Uranium is exported under conditions laid down to avoid any nuclear proliferation. On 24 May 1977 the Prime Minister had stated the main elements of Australian policy: the strengthening of the system of international safeguards and the selection of importing countries. (Non-nuclear weapon states must be Contracting Parties to the NPT. Nuclear weapon states must undertake not to use Australian uranium for this purpose). Australia retains property of the uranium up to the UF 6 stage (uranium hexafluoride) in the fuel cycle; it reserves the right to stop any export if the importing country no longer complies with AIEA Safeguards. Any transfer to a third country, any irradiated fuel reprocessing, requires Australia's prior agreement. Finally, importing countries must satisfy physical protection conditions. (NEA) [fr

Nanomaterials are used in diverse fields including food, cosmetic, and medical industries. Titanium dioxide nanoparticles (TiO2-NP) are widely used, but their effects on biological systems and mechanism of toxicity have not been elucidated fully. Here, we report the toxicological mechanism of TiO2-NP in cell organelles. Human bronchial epithelial cells (16HBE14o-) were exposed to 50 and 100 μg/mL TiO2-NP for 24 and 48 h. Our results showed that TiO2-NP induced endoplasmic reticulum (ER) stress in the cells and disrupted the mitochondria-associated endoplasmic reticulum membranes (MAMs) and calcium ion balance, thereby increasing autophagy. In contrast, an inhibitor of ER stress, tauroursodeoxycholic acid (TUDCA), mitigated the cellular toxic response, suggesting that TiO2-NP promoted toxicity via ER stress. This novel mechanism of TiO2-NP toxicity in human bronchial epithelial cells suggests that further exhaustive research on the harmful effects of these nanoparticles in relevant organisms is needed for their safe application.

This study aimed to confirm the ameliorative effect of ghrelin on asthma and investigate its mechanism. The murine model of asthma was induced by ovalbumin (OVA) treatment and assessed by histological pathology and airway responsiveness to methacholine. The total and differential leukocytes were counted. Tumor necrosis factor α, interferon γ, interleukin-5 and interleukin-13 levels in bronchoalveolar lavage fluid were quantified by commercial kits. The protein levels in pulmonary tissues were measured by Western blot analysis. Ghrelin ameliorated the histological pathology and airway hyperresponsiveness in the OVA-induced asthmatic mouse model. Consistently, OVA-increased total and differential leukocytes and levels of tumor necrosis factor α, interferon γ, interleukin-5 and interleukin-13 in bronchoalveolar lavage fluid were significantly attenuated by ghrelin. Ghrelin prevented the increased protein levels of the endoplasmic reticulum stress markers glucose regulated protein 78 and CCAAT/enhancer binding protein homologous protein and reversed the reduced levels of p-Akt in asthmatic mice. Ghrelin might prevent endoplasmic reticulum stress activation by stimulating the Akt signaling pathway, which attenuated inflammation and ameliorated asthma in mice. Ghrelin might be a new target for asthma therapy. Copyright © 2017. Published by Elsevier Inc.

1986-01-01

Nuclear energy offers all possibilities to reduce the energy problems in the world which arise with the world-wide increasing population and the energy demand connected with it. The Federal Republic of Germany lives on the exports of refined technical methods which also include nuclear engineering. The exports of nuclear engineering should lead to a technology transfer with guidance and training on an equal basis between the industrial and developing countries. The preconditions of exporting nuclear-technical systems are a well-functioning domestic market and a certain support by the government, especially with regard to giving guarantees for the special exports risks of these big projects. On the other hand, exports are also needed in order to be able to continue providing high-level technology for the domestic market. (UA) [de

Energy content in manufacturing exports: A cross-country analysis

International Nuclear Information System (INIS)

Amador, João

2012-01-01

This article compares the energy content in manufacturing exports in a set of 30 advanced and emerging economies and examines its evolution from 1995 to 2005, combining information from the OECD input–output matrices and international trade data in 17 manufacturing sectors. In addition, the article suggests a methodology to disentangle export structure and sectoral energy efficiency effects, presenting results according to technological categories. The article concludes that Brazil, India and, mostly, China, present a high energy content in manufacturing exports, which has increased from 1995 to 2005. Conversely, many advanced economies, notably in Europe and North America, which showed energy contents below the world average in 1995, reinforced their position as exporters with relatively lower energy usage. The contribution of export structure and energy efficiency effects to explain differences in the energy content of exports draws attention to the situation of China. This country increased its relative energy usage in the exports of all technological categories of goods. This effect was reinforced by the stronger export specialization in high-tech products and hindered by a comparatively lower specialization in medium-high-tech products. - Highlights: ► We compare the energy content in manufacturing exports in advanced and emerging economies. ► We suggest a methodology to disentangle export structure and sectoral energy efficiency effects. ► Large emerging economies present high energy content in manufacturing exports. ► China increased its relative energy usage in the exports of all technological categories of goods.

Full Text Available Nonprice competition is increasingly important in world food markets. Recently, the expression ‘export sophistication’ has been introduced in the economic literature to refer to a wide set of attributes that increase product value. An index has been proposed to measure sophistication in an indirect way through the per capita GDP of exporting countries (Lall et al., 2006; Haussmann et al., 2007.The paper applies the sophistication measure to the Italian food export sector, moving from an analysis of trends and performance of Italian food exports. An original way to disentangle different components in the temporal variation of the sophistication index is also proposed.Results show that the sophistication index offers original insights on recent trends in world food exports and with respect to Italian core food exports.

An evaluation of Kazakhstan nuclear export control system

International Nuclear Information System (INIS)

Yeligbayeva, G.; Masenov, Ch.

2002-01-01

A system to control the export nuclear materials and technologies is a natural part of creating a self-sustaining government. The government of Kazakhstan has made a great deal of progress in building such a system. Control of export and import of nuclear materials and technologies and dual-use materials, related to nuclear activity, became one of the important part of mechanism of Non-Proliferation conditions realization in Kazakhstan. The system of export control has developed well over the 10 years. Kazakhstan is in the midst of a long process of building a functional export control system consistent with World standards. The state system of export control currently exists in Kazakhstan on the legislative base, and is based on efficient cooperation of the KAEC with a number of competent state bodies (Ministry of Economy, Ministry of Foreign Affairs, State Customs Committee) each of them has its own specific functions, duties and rights. The export is carried out using licenses, issued by the Ministry of Economy of the RK, according to applications of certain standard which are previously agreed with the KAEC under decision of the RK Government. The KAEC, acting on the base of export control principles and observance of international obligations on non-proliferation matter, makes decisions, only after thorough evaluation of ways of export and reliability of an end-user of the commodity, to agree the application for a license. The most fully developed aspect is the licensing process. General politics of export regulation in Kazakhstan are based on normative acts and rules, which are wholly appropriate (complementary) to the managing principles of nuclear export. There exists a full legal basis for the licensing system. But the process is going, some provisions is changing: in 2000 Kazakhstan corrected the export control law and approved the national control list very similar with EU control list, in 2002 the rules of the process of licensing the export and import

In Vitro Reconstitution of Functional Type III Protein Export and Insights into Flagellar Assembly.

The type III secretion system (T3SS) forms the functional core of injectisomes, protein transporters that allow bacteria to deliver virulence factors into their hosts for infection, and flagella, which are critical for many pathogens to reach the site of infection. In spite of intensive genetic and biochemical studies, the T3SS protein export mechanism remains unclear due to the difficulty of accurate measurement of protein export in vivo Here, we developed an in vitro flagellar T3S protein transport assay system using an inverted cytoplasmic membrane vesicle (IMV) for accurate and controlled measurements of flagellar protein export. We show that the flagellar T3SS in the IMV fully retains export activity. The flagellar hook was constructed inside the lumen of the IMV by adding purified component proteins externally to the IMV solution. We reproduced the hook length control and export specificity switch in the IMV consistent with that seen in the native cell. Previous in vivo analyses showed that flagellar protein export is driven by proton motive force (PMF) and facilitated by ATP hydrolysis by FliI, a T3SS-specific ATPase. Our in vitro assay recapitulated these previous in vivo observations but furthermore clearly demonstrated that even ATP hydrolysis by FliI alone can drive flagellar protein export. Moreover, this assay showed that addition of the FliH 2 /FliI complex to the assay solution at a concentration similar to that in the cell dramatically enhanced protein export, confirming that the FliH 2 /FliI complex in the cytoplasm is important for effective protein transport. IMPORTANCE The type III secretion system (T3SS) is the functional core of the injectisome, a bacterial protein transporter used to deliver virulence proteins into host cells, and bacterial flagella, critical for many pathogens. The molecular mechanism of protein transport is still unclear due to difficulties in accurate measurements of protein transport under well-controlled conditions in

Determinants of Leather and Leather products Exports in Tanzania

Directory of Open Access Journals (Sweden)

Francis Lwesya

2018-03-01

Full Text Available This study examines the determinants of Leather and Leather products Exports in Tanzania. We apply Ordinary Least Square (OLS analysis on time series data from 1980 to 2015. The findings show that export of raw hides and skins, and high costs of production are among the deterring factors to leather and leather products export in Tanzania. Export of raw hides and skins and costs of production recorded negative and significant relationship with leather exports. On the other hand, hides and skins collection recorded insignificant relationship while leather price in the world market had negative and significant relationship with leather exports. This suggests that other factors such as low quality of leather and leather products exported, inadequate capital investment, stiff competition with foreign companies for hides and skins and inadequate market information explain the state of current Tanzania’s leather exports. Thus, attracting local and Foreign Direct Investment (FDI in the leather subsector by providing friendly investment climate and addressing the supply side constraints will enable increased high quality leather and leather products diversification and exports

The open reading frame 2 (ORF2) of Porcine circovirus type 2 (PCV2) encodes the major Capsid (Cap) protein, which self-assembles into virus-like particle (VLP) of similar morphology to the PCV2 virion and accumulates in the nucleus through the N-terminal arginine-rich nuclear localization signal (NLS). In this study, PCV2 Cap protein and its derivates were expressed via the baculovirus expression system, and the cellular localization of the recombinant proteins were investigated using anti-Cap mAb by imaging flow cytometry. Analysis of subcellular localization of Cap protein and its variants demonstrated that NLS mediated Cap protein nuclear export as well as nuclear import, and a phosphorylation site (S17) was identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) in the NLS domain to regulate Cap protein nuclear export. Phosphorylation of NLS regulating the PCV2 Cap protein nuclear export was also demonstrated in PK15 cells by fluorescence microscopy. Moreover, the influence of Rep and Rep' protein on Cap protein subcellular localization was investigated in PK15 cells. Phosphorylation of NLS regulating Cap protein nuclear export provides more detailed knowledge of the PCV2 viral life cycle. Copyright © 2018 Elsevier B.V. All rights reserved.

The serine hydrolase inhibitors pyrrophenone and KT195 inhibit cell death induced by A23187 and H 2 O 2 by blocking the release of calcium from the endoplasmic reticulum and mitochondrial calcium uptake. The effect of pyrrophenone and KT195 on these processes is not due to inhibition of their known targets, cytosolic phospholipase A 2 and α/β-hydrolase domain-containing (ABHD) 6, respectively, but represent off-target effects. To identify targets of KT195, fibroblasts were treated with KT195-alkyne to covalently label protein targets followed by click chemistry with biotin azide, enrichment on streptavidin beads and tryptic peptide analysis by mass spectrometry. Although several serine hydrolases were identified, α/β-hydrolase domain-containing 2 (ABHD2) was the only target in which both KT195 and pyrrophenone competed for binding to KT195-alkyne. ABHD2 is a serine hydrolase with a predicted transmembrane domain consistent with its pull-down from the membrane proteome. Subcellular fractionation showed localization of ABHD2 to the endoplasmic reticulum but not to mitochondria or mitochondrial-associated membranes. Knockdown of ABHD2 with shRNA attenuated calcium release from the endoplasmic reticulum, mitochondrial calcium uptake and cell death in fibroblasts stimulated with A23187. The results describe a novel mechanism for regulating calcium transfer from the endoplasmic reticulum to mitochondria that involves the serine hydrolase ABHD2. Copyright © 2017 Elsevier Inc.

2012-01-01

Background Given the relative abundance and toxic potential of acrolein in inhaled cigarette smoke, it is surprising how little is known about the pulmonary and systemic effects of acrolein. Here we test the hypothesis whether systemic administration of acrolein could cause endoplasmic reticulum (ER) stress, and lung cell apoptosis, leading to the enlargement of the alveolar air spaces in rats. Methods Acute and chronic effects of intraperitoneally administered acrolein were tested. Mean alveolar airspace area was measured by using light microscopy and imaging system software. TUNEL staining and immunohistochemistry (IHC) for active caspase 3 and Western blot analysis for active caspase 3, and caspase 12 were performed to detect apoptosis. The ER-stress related gene expression in the lungs was determined by Quantitative real-time PCR analysis. Acrolein-protein adducts in the lung tissue were detected by IHC. Results Acute administration of acrolein caused a significant elevation of activated caspase 3, upregulation of VEGF expression and induced ER stress proteins in the lung tissue. The chronic administration of acrolein in rats led to emphysematous lung tissue remodeling. TUNEL staining and IHC for cleaved caspase 3 showed a large number of apoptotic septal cells in the acrolein-treated rat lungs. Chronic acrolein administration cause the endoplasmic reticulum stress response manifested by significant upregulation of ATF4, CHOP and GADd34 expression. In smokers with COPD there was a considerable accumulation of acrolein-protein adducts in the inflammatory, airway and vascular cells. Conclusions Systemic administration of acrolein causes endoplasmic reticulum stress response, lung cell apoptosis, and chronic administration leads to the enlargement of the alveolar air spaces and emphysema in rats. The substantial accumulation of acrolein-protein adducts in the lungs of COPD patients suggest a role of acrolein in the pathogenesis of emphysema. PMID:22675432

Estimating the Cross-Shelf Export of Riverine Materials: Part 2. Estimates of Global Freshwater and Nutrient Export

Science.gov (United States)

Izett, Jonathan G.; Fennel, Katja

2018-02-01

Rivers deliver large amounts of fresh water, nutrients, and other terrestrially derived materials to the coastal ocean. Where inputs accumulate on the shelf, harmful effects such as hypoxia and eutrophication can result. In contrast, where export to the open ocean is efficient riverine inputs contribute to global biogeochemical budgets. Assessing the fate of riverine inputs is difficult on a global scale. Global ocean models are generally too coarse to resolve the relatively small scale features of river plumes. High-resolution regional models have been developed for individual river plume systems, but it is impractical to apply this approach globally to all rivers. Recently, generalized parameterizations have been proposed to estimate the export of riverine fresh water to the open ocean (Izett & Fennel, 2018, https://doi.org/10.1002/2017GB005667; Sharples et al., 2017, https://doi.org/10.1002/2016GB005483). Here the relationships of Izett and Fennel, https://doi.org/10.1002/2017GB005667 are used to derive global estimates of open-ocean export of fresh water and dissolved inorganic silicate, dissolved organic carbon, and dissolved organic and inorganic phosphorus and nitrogen. We estimate that only 15-53% of riverine fresh water reaches the open ocean directly in river plumes; nutrient export is even less efficient because of processing on continental shelves. Due to geographic differences in riverine nutrient delivery, dissolved silicate is the most efficiently exported to the open ocean (7-56.7%), while dissolved inorganic nitrogen is the least efficiently exported (2.8-44.3%). These results are consistent with previous estimates and provide a simple way to parameterize export to the open ocean in global models.

Precipitation Pattern Controls on the Dynamics and Subsequent Export of Large Wood from River Catchments

Science.gov (United States)

Seo, J.; Nakamura, F.; Chun, K.; Grant, G. E.

2011-12-01

In-stream large wood (LW) has a critical impact on the geomorphic and ecological character in river catchments, yet relatively little is known about variations in its dynamics and subsequent export in relation to different precipitation patterns and intensities. To understand these variations we used the annual volume of LW removed from 42 reservoirs in Japan and daily precipitation at or near the reservoir sites. Daily precipitation data were transformed into effective precipitation to evaluate trends in both current and antecedent precipitation, and these data were then used to explain basin variation in LW export. Model selection with generalized linear mixed models revealed that the precipitation pattern and intensity controlling LW export in small, intermediate, and large watersheds differed with latitude along the Japanese archipelago. LW export in small watersheds was well explained by effective precipitation greater than 120 mm, and showed little latitudinal variation. In contrast, LW export in intermediate and large watersheds was well explained by daily precipitation greater than 40 mm and 60 mm, respectively, and varied with latitude. In small watersheds with narrow channels and low stream discharges, mass movements (such as landslides and debris flows) are major factors in the production and transport of LW. Thus LW export in small watersheds appears to be regulated by the effective precipitation required to initiate mass movements, and shows little latitudinal change. In intermediate and large watersheds with wide channels and high stream discharges, heavy rainfall and subsequent floods regulate buoyant depth influencing the initiation of LW mobility, and thus control the amount of LW exported. In southern and central Japan, intense rainfall accompanying typhoons or localized torrential downpours lead to geomorphic disturbances, which produce massive amounts of LW delivery into channels. However, these pieces are constantly removed by high streamflows

Immune responsiveness and incidence of reticulum cell sarcoma in long-term syngeneic radiation chimeras

International Nuclear Information System (INIS)

Adorini, L.; Gorini, G.; Covelli, V.; Ballardin, E.; di Michele, A.; Bassani, B.; Metalli, P.; Doria, G.

1976-01-01

Long-term syngeneic radiation chimeras displayed a very low incidence of reticulum cell sarcoma as compared with control mice. Immune reactivity of these animals was studied in vivo by anti-dinitrophenyl antibody titer and affinity and in vitro by mitotic responsiveness to phytohemagglutinin, concanavalin A and lipopolysaccharide. Antibody titer and affinity as well as the response to T lectins were found to be increased in chimeras. These results were attributed to increased function of mature T2 cells, which could explain the reduced incidence of reticulum cell sarcoma in chimeras

Chlorhexidine-induced apoptosis or necrosis in L929 fibroblasts: A role for endoplasmic reticulum stress

International Nuclear Information System (INIS)

Faria, Gisele; Cardoso, Cristina R.B.; Larson, Roy E.; Silva, Joao S.; Rossi, Marcos A.

2009-01-01

Chlorhexidine (CHX), widely used as antiseptic and therapeutic agent in medicine and dentistry, has a toxic effect both in vivo and in vitro. The intrinsic mechanism underlying CHX-induced cytotoxicity in eukaryotic cells is, however, still unknown. A recent study from our laboratory has suggested that CHX may induce death in cultured L929 fibroblasts via endoplasmic reticulum (ER) stress. This hypothesis was further tested by means of light and electron microscopy, quantification of apoptosis and necrosis by flow cytometry, fluorescence visualization of the cytoskeleton and endoplasmic reticulum, and evaluation of the expression of 78-kDa glucose-regulated protein 78 (Grp78), a marker of activation of the unfolded protein response (UPR) in cultured L929 fibroblasts. Our finding showing increased Grp 78 expression in CHX-treated cells and the results of flow cytometry, cytoskeleton and endoplasmic reticulum fluorescence visualization, and scanning and transmission electron microscopy allowed us to suggest that CHX elicits accumulation of proteins in the endoplasmic reticulum, which causes ER overload, resulting in ER stress and cell death either by necrosis or apoptosis. It must be pointed out, however, that this does not necessarily mean that ER stress is the only way that CHX kills L929 fibroblasts, but rather that ER stress is an important target or indicator of cell death induced by this drug

Macroeconomic Effects of Export Demand in Nigeria

Bolaji Adesola Adesoye

2017-05-01

Full Text Available This study examines the macroeconomic effects of aggregate export demand in Nigeria using annual time series data between 1970 and 2013. The paper made use of the ordinary least square method to analyse the long-run relationship for the period under study. The empirical results confirm that there exists a unique and significant long-run equilibrium relationship among export volume, world income, crude oil price, domestic output, exchange rate and cost of doing business. The estimated results show that domestic income has the highest elasticity, followed by world’s output and cost of doing business, which all report positive relations. Other macroeconomic factors reported negative relationship with aggregate export volume. Thus, an important policy implication of our findings is that stabilizing Nigeria’s export earnings potential by counteracting the external factors that influence adversely the Nigerian exports such as crude oil price and cost of doing business.

Oil exporting countries need nuclear power

Stauffer, T.R.

1982-01-01

The economic rationale for nuclear power in the oil exporting countries is analysed, with the collateral objective of defining the size of the potential market in terms of the exporting countries' economic opportunities and energy needs. The need for appropriate new institutions for licensing reactors, training personnel, and starting up plants follows directly from the size of the market and the economic incentives for the oil exporters to husband gas and oil. Gas and oil resources of the Middle Eastern countries are discussed, and future electricity needs estimated. (author)

Gas Exports in Turkmenistan

International Nuclear Information System (INIS)

Vasanczki, Luca Zs.

2011-01-01

The Caspian region has been at the center of attention since Europe began seeking alternative routes to natural-gas resources. Turkmenistan has the potential to become an important gas exporter to Europe. As a landlocked country, Turkmenistan until recently has relied on post-Soviet pipeline infrastructures. The Central Asian republic has been at the mercy of Moscow's energy policy, which overlaps its foreign policy. At the same time, the revenue from gas exports is an essential part of the Turkmen national budget. This prompted Ashgabat to look for energy partners bypassing Russian territories. It started to convey natural gas first to Iran and then to China. This gave Turkmenistan strong leverage vis-a-vis Moscow. Ashgabat has not decided to export every gas molecule eastward, but, in jeopardizing its relations with Moscow, it expects more than empty pledges from Europe. On the other hand, a simple question emerges: Does Europe really need alternative sources? The answer is in the hands of Gazprom and Russian policy-makers

Fluorescence methods for analysis of interactions between Ca(2+) signaling, lysosomes, and endoplasmic reticulum.

Science.gov (United States)

Prole, David L; López-Sanjurjo, Cristina I; Tovey, Stephen C; Taylor, Colin W

2015-01-01

The endoplasmic reticulum (ER) is both the major source of intracellular Ca(2+) for cell signaling and the organelle that forms the most extensive contacts with the plasma membrane and other organelles. Lysosomes fulfill important roles in degrading cellular materials and in cholesterol handling, but they also contribute to Ca(2+) signaling by both releasing and sequestering Ca(2+). Interactions between ER and other Ca(2+)-transporting membranes, notably mitochondria and the plasma membrane, often occur at sites where the two membranes are closely apposed, allowing local Ca(2+) signaling between them. These interactions are often facilitated by scaffold proteins. Recent evidence suggests similar local interactions between ER and lysosomes. We describe simple fluorescence-based methods that allow the interplay between Ca(2+) signals, the ER, and lysosomes to be examined. Copyright © 2015 Elsevier Inc. All rights reserved.

Scenarios for Russia's natural gas exports to 2050

International Nuclear Information System (INIS)

Paltsev, Sergey

2014-01-01

Russia is an important energy supplier as it holds the world's largest natural gas reserves and it is the world's largest exporter of natural gas. Despite a recent reduction in Russia's exports to Europe, it plans to build new pipelines. We explore the long-term (up to 2050) scenarios of Russian natural gas exports to Europe and Asia using the MIT Emissions Prediction and Policy Analysis (EPPA) model, a computable general equilibrium model of the world economy. We found that over the next 20–40 years natural gas can still play a substantial role in Russian exports and there are substantial reserves to support a development of the gas-oriented energy system both in Russia and in its current and potential gas importers. Based on the considered scenarios, Russia does not need any new pipeline capacity to the EU unless it wants to diversify its export routes to supply the EU without any gas transit via Ukraine and Belarus. Asian markets are attractive to Russian gas and substantial volumes may be exported there. Relatively cheap shale gas in China may sufficiently alter the prospects of Russian gas, especially in Asian markets. In the Reference scenario, exports of natural gas grow from Russia's current 7 Tcf to 11–12 Tcf in 2030 and 13–14 Tcf in 2050. Alternative scenarios provide a wider range of projections, with a share of Russian gas exports shipped to Asian markets rising to more than 30% by 2030 and almost 50% in 2050. Europe's reliance on LNG imports increases, while it still maintains sizable imports from Russia. - Highlights: • In the Reference scenario exports of natural gas grow from Russia’s current 7 Tcf to 11–12 Tcf in 2030 and 13–14 Tcf in 2050. • In alternative scenarios a share of Russian exports to Asian markets is rising to about 30% by 2030 and 50 % in 2050. • Cheap shale gas in China can sufficiently alter Russian natural gas export. • Reduction in nuclear generation in Europe can lead to increased exports of natural gas from

Horticultural Exports of Developing Countries: Issues under WTO Regime

Directory of Open Access Journals (Sweden)

Deepak Shah

2008-03-01

Full Text Available This paper seeks to evaluate the present and future prospects of developing and developed countries in agricultural exports in general and in horticultural exports in particular. The study also evaluates the behaviour of international export prices for agricultural commodities, both for developing and developed nations. In general, this study provides an insight into the direction in which various developed and developing countries are heading for insofar as their agricultural and horticultural exports are concerned in the changed market conditions. The study has made a few major observations. First, the study shows decline in market share of developing countries’ in world agricultural exports in the face of marginal increase in their market share in world fruits and vegetable (F&V exports during the period between 1981 and 1997. Second, although the study shows lower market share of developing countries’ in world F&V exports during the period between 1981 and 1997, the growth in F&V exports as proportion of total agricultural exports is noticed to be much faster for developing countries’ as against the developed countries’ during the same period. Third, though agricultural exports of Least Developed Countries (LDC have grown only marginally between 1981 and 1997, the growth in their F&V exports is seen to have been tremendous, especially after the late eighties period. Similarly, Socialist Countries of Asia (SCA and developing countries of Oceania have also shown sharp increases in their F&V exports after the late eighties period. Fourth, while except America, other Africa and Oceania, all the developing countries have shown decline in their market share in total F&V exports of Developing Market Economies (DME, Asia shows rise in its market share not only in agriculture but also in F&V exports of DME. Another major observation of this study is in terms of instabilities in export prices. The instabilities in export prices of agricultural

Mesoscale Effects on Carbon Export: A Global Perspective

Science.gov (United States)

Harrison, Cheryl S.; Long, Matthew C.; Lovenduski, Nicole S.; Moore, Jefferson K.

2018-04-01

Carbon export from the surface to the deep ocean is a primary control on global carbon budgets and is mediated by plankton that are sensitive to physical forcing. Earth system models generally do not resolve ocean mesoscale circulation (O(10-100) km), scales that strongly affect transport of nutrients and plankton. The role of mesoscale circulation in modulating export is evaluated by comparing global ocean simulations conducted at 1° and 0.1° horizontal resolution. Mesoscale resolution produces a small reduction in globally integrated export production (export production can be large (±50%), with compensating effects in different ocean basins. With mesoscale resolution, improved representation of coastal jets block off-shelf transport, leading to lower export in regions where shelf-derived nutrients fuel production. Export is further reduced in these regions by resolution of mesoscale turbulence, which restricts the spatial area of production. Maximum mixed layer depths are narrower and deeper across the Subantarctic at higher resolution, driving locally stronger nutrient entrainment and enhanced summer export production. In energetic regions with seasonal blooms, such as the Subantarctic and North Pacific, internally generated mesoscale variability drives substantial interannual variation in local export production. These results suggest that biogeochemical tracer dynamics show different sensitivities to transport biases than temperature and salinity, which should be considered in the formulation and validation of physical parameterizations. Efforts to compare estimates of export production from observations and models should account for large variability in space and time expected for regions strongly affected by mesoscale circulation.

Carbon partitioning and export from mature cotton leaves

International Nuclear Information System (INIS)

Hendrix, D.L.; Grange, R.I.

1991-01-01

The partitioning of carbon in intact, mature cotton (Gossypium hirsutum L.) leaves was examined by steady-state 14 CO 2 labeling. Plants were exposed to dark periods of varying lengths, followed by similar illuminated labeling periods. These treatments produced leaves with a range of starch and soluble sugar contents, carbon exchange, and carbon export rates. Export during the illuminated periods was neither highly correlated with photosynthesis nor was export during the illuminated periods significantly different among the treatments. In contrast, the rate of subsequent nocturnal carbon export from these leaves varied widely and was found to be highly correlated with leaf starch content at the end of the illumination period and with nocturnal leaf respiration. Leaves which had accumulated the highest levels of starch (about 275 micrograms per square centimeter) by the end of the illumination period exhibited nocturnal export rates very similar to those during the daylight hours. Leaves which accumulated starch to only 50 to 75 micrograms per square centimeter virtually ceased nocturnal carbon export. For leaves with starch accumulations of between 50 and 275 micrograms per square centimeter, nocturnal export was directly proportional to leaf starch at the end of the illumination period. After the nocturnal export rate was established, it continued at a constant rate throughout the night even though leaf starch and sucrose contents declined

The partitioning of carbon in intact, mature cotton (Gossypium hirsutum L.) leaves was examined by steady-state (14)CO(2) labeling. Plants were exposed to dark periods of varying lengths, followed by similar illuminated labeling periods. These treatments produced leaves with a range of starch and soluble sugar contents, carbon exchange, and carbon export rates. Export during the illuminated periods was neither highly correlated with photosynthesis nor was export during the illuminated periods significantly different among the treatments. In contrast, the rate of subsequent nocturnal carbon export from these leaves varied widely and was found to be highly correlated with leaf starch content at the end of the illumination period (r = 0.934) and with nocturnal leaf respiration (r = 0.954). Leaves which had accumulated the highest levels of starch (about 275 micrograms per square centimeter) by the end of the illumination period exhibited nocturnal export rates very similar to those during the daylight hours. Leaves which accumulated starch to only 50 to 75 micrograms per square centimeter virtually ceased nocturnal carbon export. For leaves with starch accumulations of between 50 and 275 micrograms per square centimeter, nocturnal export was directly proportional to leaf starch at the end of the illumination period. After the nocturnal export rate was established, it continued at a constant rate throughout the night even though leaf starch and sucrose contents declined.

Sphingosine inhibits the sarco(endo)plasmic reticulum Ca"2"+-ATPase (SERCA) activity

International Nuclear Information System (INIS)

Benaim, Gustavo; Pimentel, Adriana A.; Felibertt, Pimali; Mayora, Adriana; Colman, Laura; Sojo, Felipe; Rojas, Héctor; De Sanctis, Juan B.

2016-01-01

The increase in the intracellular Ca"2"+ concentration ([Ca"2"+]_i) is the key variable for many different processes, ranging from regulation of cell proliferation to apoptosis. In this work we demonstrated that the sphingolipid sphingosine (Sph) increases the [Ca"2"+]_i by inhibiting the sarco(endo)plasmic reticulum Ca"2"+-ATPase (SERCA), in a similar manner to thapsigargin (Tg), a specific inhibitor of this Ca"2"+ pump. The results showed that addition of sphingosine produced a release of Ca"2"+ from the endoplasmic reticulum followed by a Ca"2"+ entrance from the outside mileu. The results presented in this work support that this sphingolipid could control the activity of the SERCA, and hence sphingosine may participate in the regulation of [Ca"2"+]_I in mammalian cells.

Joint industry planning platforms for coal export supply chains

Energy Technology Data Exchange (ETDEWEB)

Improving the performance and reducing the costs associated with export logistics chain is critical to the competitiveness of export coal mines. The fundamental practices associated with the use of export logistics chains made up of mine, trucking, rail and port operations are being challenged by the advent of third party operators on rail systems and the use of the Internet. Whilst individual mines can improve their processes to drive down their mining costs, they face major challenges in their endeavour to improve the performance of export logistics chains and reduce the significant logistics costs of moving coal from the mine to export ships, via the shared infrastructure of rail systems and ports. There is an increasing realisation that global competition is not only between mines but between coal export regions that are defined by their rail system and ports infrastructure. The development and use of a joint industry planning platform for the export logistics chains of the Western Australian Grain Industry has demonstrated that an industry facing significant restructuring and increased competitiveness can achieve major throughput and cost reduction gains when stakeholders in export logistics chains share key planning information using the Internet and state of the art planning tools. Joint industry planning platforms for export logistics chains are being considered or are at initial stages of development for a number of Australasian coal export logistics chains. This paper addresses the key components of joint industry planning platforms, the key information that should be shared, the use of the internet and information servers, and the contractual structures required to enable stakeholders of an export logistics chain, who are competitors or potential competitors, to work together to improve the competitiveness of a coal export region. 4 refs., 6 figs.

Integration of mRNP formation and export.

Science.gov (United States)

Björk, Petra; Wieslander, Lars

2017-08-01

Expression of protein-coding genes in eukaryotes relies on the coordinated action of many sophisticated molecular machineries. Transcription produces precursor mRNAs (pre-mRNAs) and the active gene provides an environment in which the pre-mRNAs are processed, folded, and assembled into RNA-protein (RNP) complexes. The dynamic pre-mRNPs incorporate the growing transcript, proteins, and the processing machineries, as well as the specific protein marks left after processing that are essential for export and the cytoplasmic fate of the mRNPs. After release from the gene, the mRNPs move by diffusion within the interchromatin compartment, making up pools of mRNPs. Here, splicing and polyadenylation can be completed and the mRNPs recruit the major export receptor NXF1. Export competent mRNPs interact with the nuclear pore complex, leading to export, concomitant with compositional and conformational changes of the mRNPs. We summarize the integrated nuclear processes involved in the formation and export of mRNPs.

Due to the important role of rifamycin in curing tuberculosis infection, the study on rifamycin has never been stopped. Although RifZ, which locates within the rifamycin biosynthetic cluster, has recently been characterized as a pathway-specific regulator for rifamycin biosynthesis, little is known about the regulation of rifamycin export. In this work, we proved that the expression of the rifamycin efflux pump (RifP) was regulated by RifQ, a TetR-family transcriptional regulator. Deletion of rifQ had little impact on bacterial growth, but resulted in improved rifamycin production, which was consistent with the reverse transcription PCR results that RifQ negatively regulated rifP's transcription. With electrophoretic mobility shift assay and DNase I Footprinting assay, RifQ was found to directly bind to the promoter region of rifP, and a typical inverted repeat was identified within the RifQ-protected sequences. The transcription initiation site of rifP was further characterized and found to be upstream of the RifQ binding sites, well explaining the RifQ-mediated repression of rifP's transcription in vivo. Moreover, rifamycin B (the end product of rifamycin biosynthesis) remarkably decreased the DNA binding affinity of RifQ, which led to derepression of rifamycin export, reducing the intracellular concentration of rifamycin B as well as its toxicity against the host. Here, we proved that the export of rifamycin B was repressed by RifQ in Amycolatopsis mediterranei, and the RifQ-mediated repression could be specifically relieved by rifamycin B, the end product of rifamycin biosynthesis, based on which a feedback model was proposed for regulation of rifamycin export. With the findings here, one could improve the antibiotic yield by simply inactivating the negative regulator of the antibiotic transporter.

Firm and Product Heterogeneity in China's Automotive Exports

Directory of Open Access Journals (Sweden)

Jing Wang

2015-12-01

Full Text Available The main purpose of this paper is to provide an in-depth analysis of the anatomy of China's automotive exports, relying on the literature on firm and product heterogeneity. For this purpose, we use highly disaggregated HS 8-digit product-category level data collected by the Chinese Customs Office for 2000 and 2008, and we distinguish between foreign firms, domestic public firms, and domestic private firms. We also decompose automotive products into autos and auto parts and components (P/C. We then calculate both the extensive margins – number of products exported – and intensive margins – average value of exports per product – of China's automotive exports. We estimate gravity equations to assess the determinants of China's exports of autos and auto P/C. Overall, our analysis yields a number of new, interesting stylized facts about China's automotive exports by confirming the need for taking into account different types of heterogeneity in analyzing international trade.

Tools for Export Promotion in the Context of Globalization

Directory of Open Access Journals (Sweden)

Pugachevska Kateryna S.

2017-12-01

Full Text Available A comparative analysis of the rate of growth in exports of goods and GDP is carried out, and goods exports to GDP ratio in the context of the developed countries, developing countries, and countries with the transition economy is calculated. This allows to make a conclusion about a decrease in importance of exports as a key engine of the world economic growth during the past years. The legal basis of the WTO’s activities in terms of state support for exports is described. The main reasons for the emergence of a conflict of interests between countries with different levels of economic development concerning the use of individual protectionist barriers are revealed. Potential long-term consequences of the growth of export orientation under conditions of openness of national economies are identified. The measures and tools of the country’s export promotion in foreign markets are studied. It is grounded that under conditions of destabilization of global trade regulators, effective export promotion is a mechanism for increasing the competitiveness of the national economy of Ukraine. Prospects for further research in this area are the determination of instruments to stimulate exports, which have the greatest impact on the export orientation of certain economic activities.

The Endoplasmic Reticulum Coat Protein II Transport Machinery Coordinates Cellular Lipid Secretion and Cholesterol Biosynthesis*

Triglycerides and cholesterol are essential for life in most organisms. Triglycerides serve as the principal energy storage depot and, where vascular systems exist, as a means of energy transport. Cholesterol is essential for the functional integrity of all cellular membrane systems. The endoplasmic reticulum is the site of secretory lipoprotein production and de novo cholesterol synthesis, yet little is known about how these activities are coordinated with each other or with the activity of the COPII machinery, which transports endoplasmic reticulum cargo to the Golgi. The Sar1B component of this machinery is mutated in chylomicron retention disorder, indicating that this Sar1 isoform secures delivery of dietary lipids into the circulation. However, it is not known why some patients with chylomicron retention disorder develop hepatic steatosis, despite impaired intestinal fat malabsorption, and why very severe hypocholesterolemia develops in this condition. Here, we show that Sar1B also promotes hepatic apolipoprotein (apo) B lipoprotein secretion and that this promoting activity is coordinated with the processes regulating apoB expression and the transfer of triglycerides/cholesterol moieties onto this large lipid transport protein. We also show that although Sar1A antagonizes the lipoprotein secretion-promoting activity of Sar1B, both isoforms modulate the expression of genes encoding cholesterol biosynthetic enzymes and the synthesis of cholesterol de novo. These results not only establish that Sar1B promotes the secretion of hepatic lipids but also adds regulation of cholesterol synthesis to Sar1B's repertoire of transport functions. PMID:24338480

Export markets for nuclear technology

International Nuclear Information System (INIS)

Huettl, A.J.

1985-01-01

By late 1984, nuclear power plants were in operation or under construction in 32 countries of the globe. An additional six countries had concrete plans for building nuclear power plants. Of these 38 countries, ten have shown that they posses the necessary know-how and the technical facilities to plan and build nuclear power plants practically on their own. Seven of these ten countries have already acted as exporters of nuclear power plants, albeit with very different degrees of market penetration. In addition, there have been a number of countries for quite some time whose industries have managed to manufacture many important nuclear power plant components. Their high level of technical development and the problems frequently encountered in export financing have made them very attractive partners of the true exporters of nuclear power plants. For the future, it must be expected that some of the countries which have so far limited their efforts to the construction of nuclear power plants at home will also develop into exporters of nuclear technology. The report contains a survey of the range of nuclear products available, a list of reactor vendors, reactor lines, and data on the economics of electricity generation in nuclear plants. It then goes on to offer detailed descriptions of the market and the demand situation. Interesting chapters are devoted to the selection criteria applied by importing countries, to financing problems, and to the influences exerted by the political environment. A realistic forecast is attempted in order to make a quantitative analysis of possible export contracts up until the year 2000. (orig.) [de

Technological Exports and the Dynamics of Ukraine’s Economic Growth

Directory of Open Access Journals (Sweden)

Natalia Cherkass

2006-03-01

Full Text Available This article examines the promotion of technological exports in the context of making products competitive on the world market at the expense of quantified but not qualified factors. The author describes the destructive consequences of primary export growth. Relying on a designed structural model, she analyzes factors pertaining to technological exports and industrial production, and also evaluates the effectiveness of promoting exports for economic growth. She demonstrates the negative effect of the devaluation of the hryvnia on industrial production growth and the currency’s neutrality as a factor in the promotion of technological exports. The article establishes that technological exports determine to a considerable extent the dynamics of Ukraine’s economic growth, while the exports of raw materials worsen these indicators. The author shows that the export of metal products stands in the way of increasing technological export, and offers her recommendations to improve the dynamics of economic growth.

A biochemical framework for eIF4E-dependent mRNA export and nuclear recycling of the export machinery.

Science.gov (United States)

Volpon, Laurent; Culjkovic-Kraljacic, Biljana; Sohn, Hye Seon; Blanchet-Cohen, Alexis; Osborne, Michael J; Borden, Katherine L B

2017-06-01

The eukaryotic translation initiation factor eIF4E acts in the nuclear export and translation of a subset of mRNAs. Both of these functions contribute to its oncogenic potential. While the biochemical mechanisms that underlie translation are relatively well understood, the molecular basis for eIF4E's role in mRNA export remains largely unexplored. To date, over 3000 transcripts, many encoding oncoproteins, were identified as potential nuclear eIF4E export targets. These target RNAs typically contain a ∼50-nucleotide eIF4E sensitivity element (4ESE) in the 3' UTR and a 7-methylguanosine cap on the 5' end. While eIF4E associates with the cap, an unknown factor recognizes the 4ESE element. We previously identified cofactors that functionally interacted with eIF4E in mammalian cell nuclei including the leucine-rich pentatricopeptide repeat protein LRPPRC and the export receptor CRM1/XPO1. LRPPRC simultaneously interacts with both eIF4E bound to the 5' mRNA cap and the 4ESE element in the 3' UTR. In this way, LRPPRC serves as a specificity factor to recruit 4ESE-containing RNAs within the nucleus. Further, we show that CRM1 directly binds LRPPRC likely acting as the export receptor for the LRPPRC-eIF4E-4ESE RNA complex. We also found that Importin 8, the nuclear importer for cap-free eIF4E, imports RNA-free LRPPRC, potentially providing both coordinated nuclear recycling of the export machinery and an important surveillance mechanism to prevent futile export cycles. Our studies provide the first biochemical framework for the eIF4E-dependent mRNA export pathway. © 2017 Volpon et al.; Published by Cold Spring Harbor Laboratory Press for the RNA Society.

The paper describes the export licensing procedure and the modifications made to it under the 1978 Nuclear Non-Proliferation Act (NNPA) to achieve greater control over exports of nuclear material and facilities. Export licences from the Nuclear Regulatory Commission are now required for certain items connected with nuclear plant construction and the procedure for obtaining the views of the Executive Branch have been formalised. The President is enabled to override the denial of an export licence by the NRC. Amongst the new criteria on the export licensing procedure added to the 1954 Atomic Energy Act, the NNPA provides that the IAEA Safeguards under the Non-Proliferation Treaty are applicable to exported nuclear material or facilities, together with adequate physical protection measures.

New opportunities for U.S. coal and mineral exporters

International Nuclear Information System (INIS)

Watkins, J.A.

1992-01-01

U.S. exports of coal, metals and industrial minerals to the European Community were valued at $2.4 billion in 1989, representing 47 percent of total export revenues generated by these materials. Coal was the single largest contributor to the value of mineral exports to the EC with total sales of approximately $2 billion in 1989. With the extinction of trade barriers that will be triggered by the economic and political unification of Europe, new opportunities for U.S. minerals exporters are likely to develop. This paper examines the overall impact of European integration on U.S. metal and industrial mineral exports and provides a more rigorous analysis of the outlook for thermal and coking coal exports to the EC during the next decade

Purification of a sarcoplasmic reticulum protein that binds Ca2+ and plasma lipoproteins

International Nuclear Information System (INIS)

Hofmann, S.L.; Brown, M.S.; Lee, E.; Pathak, R.K.; Anderson, R.G.; Goldstein, J.L.

1989-01-01

A protein in the sarcoplasmic reticulum of rabbit skeletal and cardiac muscle was identified because of its ability to bind 125I-labeled low density lipoprotein (LDL) with high affinity after sodium dodecyl sulfate-polyacrylamide gel electrophoresis. This protein, referred to as the 165-kDa protein, is restricted to striated muscle. It was not detected in 14 other tissues, including several that contain smooth muscle, but it appears in rat L6 myoblasts when they differentiate into myocytes. Immunofluorescence and immunoelectron microscopic studies revealed that the protein is present throughout the sarcoplasmic reticulum and the terminal cisternae. It binds 45Ca2+ on nitrocellulose blots and stains metachromatically with Stains-all, a cationic dye that stains Ca2+-binding proteins. It does not appear to be a glycoprotein, and it appears slightly larger than the 160-kDa glycoprotein previously described in sarcoplasmic reticulum. The 165-kDa protein binds LDL, beta-migrating very low density lipoprotein, and a cholesterol-induced high density lipoprotein particle that contains apoprotein E as its sole apoprotein with much higher affinity than it binds high density lipoprotein. The protein is stable to boiling and to treatment with sodium dodecyl sulfate, but it becomes sensitive to these treatments when its cystine residues are reduced and alkylated. The protein was purified 1300-fold to apparent homogeneity from rabbit skeletal muscle membranes. It differs from the cell surface LDL receptor in that (1) its apparent molecular weight is not changed by reduction and alkylation; (2) it is present in Watanabe-heritable hyperlipidemic rabbits, which lack functional LDL receptors; (3) binding of lipoproteins is not inhibited by EDTA; and (4) it is located within the lumen of the sarcoplasmic reticulum where it has no access to plasma lipoproteins

The NPT and nuclear export controls

International Nuclear Information System (INIS)

Berkhout, F.

1992-01-01

Controls on the export of nuclear materials and technology were originally imposed in wartime and under the United States Atomic Energy Act of 1946 to restrict the supply of uranium. But there was no international agreement until the mid 1960s; before that the United States, Canada, France and the Soviet Union imposed export controls on a national basis. The Non-Proliferation Treaty, especially Articles I-IV, set out the first world wide controls on the nuclear trade. These articles are explained in the context of the relevant Committees (the Zangger Committee, the Committee on the Assurance of Supply, the National Export Committee and the Coordinating Committee for Multilateral Export Control) and Guidelines (the Nuclear Suppliers Guidelines and the International Nuclear Fuel Cycle Evaluation). Recent developments which have a bearing on nuclear trade, such as the single European market, the emergence of new supplies and the break-up of the Soviet Union, are considered. (UK)

The statistics compiled by the German Federal Office for Industry (Bundesamt fuer Wirtschaft), on behalf of the Federal Ministry for the Environment, Protection of Nature, and Reactor Safety, of the imports and exports of radionuclides, irradiation samples, and sealed emitters of more than 1850 GBq show an enormous increase by 152.7% of imports (on the basis of activity) and a decline by 19.5% of exports. In the category of imports, some 98% of the total activity were made up of the H-3, Co-60, Mo-99, and Ir-192 nuclides. In the category of sealed emitters, the imports of Co-60 have trebled. In the exports category, more than 95% of the total activity were made up of the H-3, Mo-99, and Ir-192 nuclides. In the category of sealed emitters, exports of Cs-137 experienced a fourfold increase over the level of the previous year. (orig.) [de

The current non-proliferation regime requires strengthening the export control from Korea to foreign countries. This means that the ministries related to export control deeply emphasize the prohibition of the illegal proliferation in the domestic society as well as international society. The principle of export control for non-proliferation of WMD is to control the transfer of the strategic items/technology to the countries which intend to develop the WMD in accordance with the multilateral agreements of the Nuclear Supply Group (NSG), Wassenaar Agreement (WA), Austrian Group (AG) and Missile Technology Control Regime (MTCR). Among them, export controls at KAERI are deeply related to the guidelines of the NSG, an international nuclear export control regime. Since the new concept of an export system was launched in Jan. 2014, KAERI needs to consider new approaches to meet the requirement of the revised domestic law and regulation. To cope with this environmental change, this paper suggests new approaches to effectively conduct the export control at KAERI

Method for continuous measurement of export from a leaf

Geiger, D.R.; Fondy, B.R.

1979-01-01

Export of labeled material derived by continuous photosynthesis in 14 CO 2 was monitored with a Geiger-Mueller detector positioned next to an exporting leaf blade. Rate of export of labeled material was calculated from the difference between rates of retention and net photosynthesis of labeled carbon for the observed leaf. Given certain conditions, including nearly constant distribution of labeled material among minor veins and various types of cells, count rate data for the source leaf can be coverted to rate of export of carbon. Changes in counting efficiency resulting from changes in leaf water status can be corrected for with data from a transducer which measures leaf thickness. Export data agreed with data obtained by monitoring the arrival of 14 C in the sink region; isolated leaves gave values near zero for export of labeled carbon from a given leaf on an intact plant. The technique detects changes in export with a resolution of 10 to 20 minutes

HIV-1's Rev protein forms a homo-oligomeric adaptor complex linking viral RNAs to the cellular CRM1/Ran-GTP nuclear export machinery through the activity of Rev's prototypical leucine-rich nuclear export signal (NES). In this study, we used a functional fluorescently tagged Rev fusion protein as a platform to study the effects of modulating Rev NES identity, number, position, or strength on Rev subcellular trafficking, viral RNA nuclear export, and infectious virion production. We found that Rev activity was remarkably tolerant of diverse NES sequences, including supraphysiological NES (SNES) peptides that otherwise arrest CRM1 transport complexes at nuclear pores. Rev's ability to tolerate a SNES was both position and multimerization dependent, an observation consistent with a model wherein Rev self-association acts to transiently mask the NES peptide(s), thereby biasing Rev's trafficking into the nucleus. Combined imaging and functional assays also indicated that NES masking underpins Rev's well-known tendency to accumulate at the nucleolus, as well as Rev's capacity to activate optimal levels of late viral gene expression. We propose that Rev multimerization and NES masking regulates Rev's trafficking to and retention within the nucleus even prior to RNA binding. HIV-1 infects more than 34 million people worldwide causing >1 million deaths per year. Infectious virion production is activated by the essential viral Rev protein that mediates nuclear export of intron-bearing late-stage viral mRNAs. Rev's shuttling into and out of the nucleus is regulated by the antagonistic activities of both a peptide-encoded N-terminal nuclear localization signal and C-terminal nuclear export signal (NES). How Rev and related viral proteins balance strong import and export activities in order to achieve optimal levels of viral gene expression is incompletely understood. We provide evidence that multimerization provides a mechanism by which Rev transiently masks its NES peptide

Export diversification and structural changes in South Africa

Full Text Available What is the nature and extent of export diversification in South Africa? The primary purpose of this paper is to seek empirical answers to this question. In an attempt to derive empirical measures of the extent of export diversification and the structural changes taking place in South Africa, this paper uses a sample of a group of 28 selected commodities for the period 1980-2012 for which the most recent data is available. The following methods were used to measure the extent of export diversification and the structural changes in export diversification: Commodity-specific cumulative export Experience function, the Commodity-specific traditional index (CSTI, variance of CSTI, concentration ratio and the aggregate specialisation index. The Commodity-Specific Cumulative Experience Function plots show that roughly, commodities such as scientific equipment, transport equipment, motor vehicles, furniture, machinery and electronic products were shifted to the right indicating that the commodities are non-traditional in nature whereas gold coal agricultural products and wood are traditional in nature. The CSTI rankings indicated that motor vehicle exports ranked first showing that motor vehicles are non-traditional exports. Findings of this paper corroborate findings of other scholars; we conclude that our results are complementary.

Crystal structure of the Xpo1p nuclear export complex bound to the SxFG/PxFG repeats of the nucleoporin Nup42p.

Xpo1p (yeast CRM1) is the major nuclear export receptor that carries a plethora of proteins and ribonucleoproteins from the nucleus to cytoplasm. The passage of the Xpo1p nuclear export complex through nuclear pore complexes (NPCs) is facilitated by interactions with nucleoporins (Nups) containing extensive repeats of phenylalanine-glycine (so-called FG repeats), although the precise role of each Nup in the nuclear export reaction remains incompletely understood. Here we report structural and biochemical characterization of the interactions between the Xpo1p nuclear export complex and the FG repeats of Nup42p, a nucleoporin localized at the cytoplasmic face of yeast NPCs and has characteristic SxFG/PxFG sequence repeat motif. The crystal structure of Xpo1p-PKI-Nup42p-Gsp1p-GTP complex identified three binding sites for the SxFG/PxFG repeats on HEAT repeats 14-20 of Xpo1p. Mutational analyses of Nup42p showed that the conserved serines and prolines in the SxFG/PxFG repeats contribute to Xpo1p-Nup42p binding. Our structural and biochemical data suggest that SxFG/PxFG-Nups such as Nup42p and Nup159p at the cytoplasmic face of NPCs provide high-affinity docking sites for the Xpo1p nuclear export complex in the terminal stage of NPC passage and that subsequent disassembly of the nuclear export complex facilitates recycling of free Xpo1p back to the nucleus. © 2017 Molecular Biology Society of Japan and John Wiley & Sons Australia, Ltd.

Final argument on regulation of electricity exports

Energy Technology Data Exchange (ETDEWEB)

1987-01-01

Ontario Hydro addresses the request of the National Energy Board review that parties comment on the broader question of the need for federal regulation in electricity exports and the objectives which underlie the view expressed. Electricity exports benefit Canadian sellers and U.S. purchasers as well the Canadian economy in general. There is a clear consensus that these benefits exist and should be realized, but the evidence indicates that there is no consensus on how the benefits can best be distributed within Canada. The divergent views expressed by interested parties from across Canada clearly demonstrate the complexity associated with determining the overall Canadian interest and that there is a need for a balancing of these interests by a federal body. The regulation of electricity exports is clearly a matter of international commerce and Ontario Hydro submitted that the Constitution Act deems the province incompetent to regulate the export of electricity from Canada. Ontario Hydro submitted that a federal body is required in the regulation of electricity exports to protect the broader Canadian interest.

The Bacterial Flagellar Type III Export Gate Complex Is a Dual Fuel Engine That Can Use Both H+ and Na+ for Flagellar Protein Export.

Directory of Open Access Journals (Sweden)

Tohru Minamino

2016-03-01

Full Text Available The bacterial flagellar type III export apparatus utilizes ATP and proton motive force (PMF to transport flagellar proteins to the distal end of the growing flagellar structure for self-assembly. The transmembrane export gate complex is a H+-protein antiporter, of which activity is greatly augmented by an associated cytoplasmic ATPase complex. Here, we report that the export gate complex can use sodium motive force (SMF in addition to PMF across the cytoplasmic membrane to drive protein export. Protein export was considerably reduced in the absence of the ATPase complex and a pH gradient across the membrane, but Na+ increased it dramatically. Phenamil, a blocker of Na+ translocation, inhibited protein export. Overexpression of FlhA increased the intracellular Na+ concentration in the presence of 100 mM NaCl but not in its absence, suggesting that FlhA acts as a Na+ channel. In wild-type cells, however, neither Na+ nor phenamil affected protein export, indicating that the Na+ channel activity of FlhA is suppressed by the ATPase complex. We propose that the export gate by itself is a dual fuel engine that uses both PMF and SMF for protein export and that the ATPase complex switches this dual fuel engine into a PMF-driven export machinery to become much more robust against environmental changes in external pH and Na+ concentration.

1978-01-01

The factors influencing the evolution of Canada's nuclear export policy are examined. Initially, nuclear technology was exported to establish an industry in Canada and to share the technology with other countries. After 1974 an increasingly broad range of political and social factors were taken into account and safeguards became the dominant factor. The indirect impacts of the new policy fall into two groups. One consists of the effects of Canada's leadership in taking a tough stand on safeguards. The second group of effects involve the concern of other countries about access to secure energy supplies and advanced technology.

An Export Promotion Policy after Financial Crisis

Directory of Open Access Journals (Sweden)

Ingyo Cheong

1998-09-01

Full Text Available Although the Korean government puts in place various export support policies after the financial crisis, Korean export is still in stagnation because the foreign-oriented economic conditions, such as the continual ripple effect of the Eastern Asia financial crisis and the American economy which is slowing down, are deteriorating. After the financial crisis, Korean trading circle considered the difficulties in financing and the buying of raw material to be the most important factors which blocked the export. This thesis first analyzed the change of the actual export results, then analyzed the policy the government brought forward as the solution of the difficulties in financing and raw material buying. Meanwhile, this thesis brought forward alternative policies like taking auto-rediscount and signing Free Trade Agreement with major trade states.

High-Resolution Imaging Reveals New Features of Nuclear Export of mRNA through the Nuclear Pore Complexes

Directory of Open Access Journals (Sweden)

Joseph M. Kelich

2014-08-01

Full Text Available The nuclear envelope (NE of eukaryotic cells provides a physical barrier for messenger RNA (mRNA and the associated proteins (mRNPs traveling from sites of transcription in the nucleus to locations of translation processing in the cytoplasm. Nuclear pore complexes (NPCs embedded in the NE serve as a dominant gateway for nuclear export of mRNA. However, the fundamental characterization of export dynamics of mRNPs through the NPC has been hindered by several technical limits. First, the size of NPC that is barely below the diffraction limit of conventional light microscopy requires a super-resolution microscopy imaging approach. Next, the fast transit of mRNPs through the NPC further demands a high temporal resolution by the imaging approach. Finally, the inherent three-dimensional (3D movements of mRNPs through the NPC demand the method to provide a 3D mapping of both transport kinetics and transport pathways of mRNPs. This review will highlight the recently developed super-resolution imaging techniques advanced from 1D to 3D for nuclear export of mRNPs and summarize the new features in the dynamic nuclear export process of mRNPs revealed from these technical advances.

Full Text Available This article proposes a theoretical analysis of the scientific approaches to defining concepts such as «exports» and «export activity». The results of the study helped to reveal that these concepts are identical, although this approach is criticized by many scientists. In the publication presented, the export activity is understood as a combination of actions on the part of the enterprises – foreign economic actors, involved in organizational arrangements aimed at preparation and marketing of goods to foreign economic actors. The article calculates the macro indicators in dynamics in order to characterize the status of Ukraine’s export activities. Its main development tendencies have been identified, the main challenges and directions for further development have been indicated. The article provides the international experience in promoting exports worldwide, the main tasks and functions of export promotion institutions have been explained, thus creating possibility to form recommendations for further actions on the part of the State to support and develop the export activity of Ukraine.

Political implications of US nuclear-export-policy development

International Nuclear Information System (INIS)

Johnson-Freese, J.S.

1981-01-01

There has been a great deal of international debate regarding how effective strict export controls on nuclear-energy supplies are toward a non-proliferation goal. With the Carter Administration, the debate was heightened by a new, more-vigorous US nuclear-export policy, much of which was codified by the Nuclear Non-Proliferation Act of 1978 (NNPA). Because of the US position in both the international non-proliferation regime and nuclear export market, the NNPA has had far-reaching consequences. The thesis of this paper is that a nuclear-export policy that fails to consider its short-term ramifications, as the NNPA has been accused of, will be self-defeating. If the US wants a viable worldwide nuclear non-proliferation policy, it must first direct its efforts toward building a domestic non-proliferation consensus, and then worldwide, rather than first setting a highly controversial policy and expecting other nations to fall into line. This work provides a comprehensive case study of US nuclear-export policy between the years 1976 to 1980 in support of the thesis. Further, the behavior and impact of the interest groups which seem to shape US nuclear-export policies is examined, and recommendations made regarding the role of groups in nuclear policy-making and implementation. Finally, recommendations are made regarding non-proliferation policy for the future, as it relates to nuclear exports

Exports of propane and butanes, January-December 1993

Tables are presented showing exports of propane and butane for each month of 1993. Comparisons with the same month in 1992 are included, as well as a running total. Export quantities are given in m 3 by region within Canada and for Canada as a whole, and as m 3 /d for Canada as a whole. Average export prices in Canadian cents per liter for the same seven regions and Canada as a whole are also given. Exports show a seasonal trend, with a low of 8,681 m 3 /d in May and a high of 18,565 m 3 in December for propane. Butane exports also show a seasonal trend with a low of 1,806 m 3 /d in June and a high of 9,306 m 3 /d in January. Propane prices ranged from 9.68 cents/l in December to 12.47 cents/l in February, compared to a range of 7.55 to 10.71 cents/l in 1992. Butane prices ranged from 9.22 cents/l in November to 12.38 cents/l in June, compared to a range of 10 to 12.78 cents/l in 1992. Total propane exports in 1993 were 4,761,795 m 3 (6.8% higher than in 1992) and total butane exports were 1,974,682 m 3 (13% lower than in 1992). 24 tabs

2002-11-12

Subcellular organelle dynamics are strongly influenced by interactions with cytoskeletal filaments and their associated motor proteins, and lead to complex multiexponential relaxations that occur over a wide range of spatial and temporal scales. Here we report spatio-temporal measurements of the fluctuations of the mitochondrial reticulum in osteosarcoma cells by using Fourier imaging correlation spectroscopy, over time and distance scales of 10(-2) to 10(3) s and 0.5-2.5 microm. We show that the method allows a more complete description of mitochondrial dynamics, through the time- and length-scale-dependent collective diffusion coefficient D(k,tau), than available by other means. Addition of either nocodazole to disrupt microtubules or cytochalasin D to disassemble microfilaments simplifies the intermediate scattering function. When both drugs are used, the reticulum morphology of mitochondria is retained even though the cytoskeletal elements have been de-polymerized. The dynamics of the organelle are then primarily diffusive and can be modeled as a collection of friction points interconnected by elastic springs. This study quantitatively characterizes organelle dynamics in terms of collective cytoskeletal interactions in living cells.

Net Biome Productivity of different land use at the sites of the Tharandt cluster

Science.gov (United States)

Grünwald, T.; Prescher, A.-K.; Bernhofer, Ch.

2009-04-01

Within the Tharandt cluster there are 5 flux monitoring sites including 3 CARBOEUROPE main sites. The CARBOEUROPE sites cover typical land use of the region (spruce [monitored since 1996], grassland [since 2003], cropland [since 2004]). For all sites estimates of the Net Biome Productivity (NBP) and its uncertainty have been derived using Net Ecosystem Productivity (NEP) based on the EC measurements and C exports and imports on an annual basis. The crop site is a small C sink (NEP of 30-110gCm-2a-1) only. The annual NEP values are dependent on the cultivated crop species (winter or summer crop). Including C export (harvest) and C import (manure spreading) lead to a considerable C source of 270-540gCm-2a-1. Organic fertilisation (C import) has a strong impact on NBP values expressed in a reduced annual net carbon source. Also, the largest interannual differences of NBP values are found at this site - mainly induced by the existence and the amount of a carbon import due to organic fertilisation. Management practices affect the NBP in a sensitive way at this crop site. Each crop shows a higher C export due to harvest than the annual NEP. To validate the calculated C equivalent using harvested grain biomass modelled NPP values are available. Uncertainty ranges of C export, C import and NBP as well as the grassland and spruce NBP (for comparison) are also stated. In general, land use and management strongly affect the annual NBP of non-forested ecosystems especially. So, this is the second main driver of the C budget besides the interannual variability in meteorological conditions and water availability with its influence on NEP, GPP and TER.

Nuclear exporters cartel

Mandelbaum, M.

1977-01-01

Events that have transpired in the past few years that have caused renewed concern about the spread of nuclear weapons are reviewed. Many proposals have been made recently for keeping the bomb from spreading. The author feels that the most novel and intriguing of them is the one advanced by Senator Abraham Ribicoff and Steven J. Baker; in their proposal, the world market for nuclear reactors would be divided into precisely defined shares among the industrial nations that now manufacture them for export; each exporter would be guaranteed a certain number of sales annually; and each would pledge not to sell uranium enrichment or plutonium reprocessing technology, as Germany did to Brazil. This might not halt proliferation, but it would give the world a few more years to find a solution

Nuclear export of cutaneous HPV8 E7 oncoprotein is mediated by a leucine-rich nuclear export signal via a CRM1 pathway

Energy Technology Data Exchange (ETDEWEB)

Onder, Zeynep; Chang, Vivian; Moroianu, Junona, E-mail: moroianu@bc.edu

2015-01-01

We recently determined that the nuclear import of cutaneous beta genus HPV8 E7 oncoprotein it is mediated by its zinc-binding domain via direct hydrophobic interactions with the FG nucleoporins Nup62 and Nup153 (Onder and Moroianu, 2014). Here we investigated the nuclear export of HPV8 E7 oncoprotein using confocal microscopy after transfections of HeLa cells with EGFP–8cE7 and mutant plasmids and treatment with Ratjadone A nuclear export inhibitor. We determined that HPV8 E7 contains a leucine-rich nuclear export signal (NES), {sub 76}IRTFQELLF{sub 84}, within its zinc-binding domain that mediates its nuclear export via a CRM1 pathway. We found that HPV8 E7 interacts with CRM1 and that the hydrophobic amino acid residues I76, F79 and L82 of the NES are essential for this interaction and for nuclear export of HPV8 E7 oncoprotein. - Highlights: • HPV8 E7 has a leucine-rich NES within its zinc-binding domain that mediates its nuclear export. • CRM1 nuclear export receptor interacts with HPV8 E7 and mediates its export. • Identification of the critical hydrophobic amino acids of the NES of HPV8 E7.

Should Australia mine and export uranium?

International Nuclear Information System (INIS)

Cobb, M.; Broadbent, Steve.

1989-01-01

In this chapter, the case for and against the mining and export of Australian uranium is discussed. For those in favour of uranium export, the nuclear energy, a source of energy which could bring a much needed boost to Australian export and employment, is being stifled by specious 'scare tactics' about the danger and misuse of uranium. It is also shown that uranium is the only feasible energy source, being cheaper, safer and cleaner when compared with other energy sources. Meanwhile, the opponents of nuclear energy, argue that uranium mining is environmentally destructive, is a danger to workers and residents health, it is bad for economy and it provides raw materials for nuclear weapons. 2 tabs

Multiple Export Mechanisms for mRNAs

Nuclear mRNA export plays an important role in gene expression. We describe the mechanisms of mRNA export including the importance of mRNP assembly, docking with the nuclear basket of the nuclear pore complex (NPC), transit through the central channel of the NPC and cytoplasmic release. We describe multiple mechanisms of mRNA export including NXF1 and CRM1 mediated pathways. Selective groups of mRNAs can be preferentially transported in order to respond to cellular stimuli. RNAs can be selected based on the presence of specific cis-acting RNA elements and binding of specific adaptor proteins. The role that dysregulation of this process plays in human disease is also discussed. PMID:26343730

It is well recognized that mandibular growth, which is caused by a variety of functional appliances, is considered to be the result of both neuromuscular and skeletal adaptations. Accumulating evidence has demonstrated that apoptosis plays an important role in the adaptation of skeletal muscle function. However, the underlying mechanism of apoptosis that is induced by stretch continues to be incompletely understood. Endoplasmic reticulum stress (ERS), a newly defined signaling pathway, initiates apoptosis. This study seeks to determine if caspase-12 is involved in stretch-induced apoptosis mediated endoplasmic reticulum stress in myoblast and its underlying mechanism. Apoptosis was assessed by Hochest staining, DAPI staining and annexin V binding and PI staining. ER chaperones, such as GRP78, CHOP and caspase-12, were determined by reverse transcription polymerase chain reaction (RT-PCR) and Western blot. Furthermore, caspase-12 inhibitor was used to value the mechanism of the caspase-12 pathway. Apoptosis of myoblast, which is subjected to cyclic stretch, was observed in a time-dependent manner. We found that GRP78 mRNA and protein were significantly increased and CHOP and caspase-12 were activated in myoblast that was exposed to cyclic stretch. Caspase-12 inhibition reduced stretch-induced apoptosis, and caspase-12 activated caspase-3 to induce apoptosis. We concluded that caspase-12 played an important role in stretch-induced apoptosis that is associated by endoplasmic reticulum stress by activating caspase-3.

Mutations of the WFS1 gene are responsible for two hereditary diseases, Wolfram syndrome and low frequency sensorineural hearing loss. The WFS1 protein is a glycoprotein located in the endoplasmic reticulum (ER) membrane but its function is poorly understood. Herein we show WFS1 mRNA and protein levels in pancreatic islets to be increased with ER-stress inducers, thapsigargin and dithiothreitol. Another ER-stress inducer, the N-glycosylation inhibitor tunicamycin, also raised WFS1 mRNA but not protein levels. Site-directed mutagenesis showed both Asn-663 and Asn-748 to be N-glycosylated in mouse WFS1 protein. The glycosylation-defective WFS1 protein, in which Asn-663 and Asn-748 had been substituted with aspartate, exhibited an increased protein turnover rate. Consistent with this, the WFS1 protein was more rapidly degraded in the presence of tunicamycin. These data indicate that ER-stress and N-glycosylation play important roles in WFS1 expression and stability, and also suggest regulatory roles for this protein in ER-stress induced cell death

Structural role of lipids in mitochondrial and sarcoplasmic reticulum membranes: freeze-fracture electron microscopy studies

Energy Technology Data Exchange (ETDEWEB)

1974-01-01

The role of phospholipid in the structure of the membranes of beef heart mitochondria and of the sarcoplasmic reticulum membranes from rabbit skeletal muscle has been investigated by freeze-fracture electron microscopy. Progressive removal of membrane phospholipids, by phospholipase A treatment or detergent treatment, or by organic solvent extraction, results in loss of the smooth background seen in membrane fracture faces and decreased ability of membrane to undergo freeze fracture to yield fracture faces. Instead cross-sections of vesicles or particle clusters are observed. Sarcoplasmic reticulum vesicles have a 9 to 1 asymmetry in the distribution of particles between the convex and concave fracture faces. There is also a wide range of particle size distribution in both of these fracture faces with 85-A particles in greatest number. The removal of membrane associated proteins by detergent extraction does not appreciably change the distribution in particle size. Sarcoplasmic reticulum vesicles were dissolved with detergent and reassembled to form membrane vesicles containing mainly one protein (approx. 90%), i.e., the Ca/sup 2 +/ pump protein, and with a ratio of lipid to protein similar to the original membrane. The reconstituted vesicles readily underwent freeze fracture but the asymmetric particle distribution between the fracture faces was no longer observed. The size distribution of particles in the reconstituted membrane, consisting mainly of Ca/sup 2 +/ pump protein, and phospholipid, was similar in heterogeneity to the original sarcoplasmic reticulum membrane. Thus the heterogeneity in particle size could reflect variation in the orientation of the Ca/sup 2 +/ pump protein within the membrane.

Abstract The majority of the total value of exports comes from small, medium-sized, and large companies for the reason that they tend to be the principal target group in public-support actions related to exports. However, micro-sized enterprises are the numerically dominant group in every economy. During recent years, micro-enterprises’ barriers for exports have lowered due to global digitalization. As a result, micro-enterprises’ share of total exports has increased rapidly in many countr...

Exporting Alaskan North Slope crude oil: Benefits and costs

Energy Technology Data Exchange (ETDEWEB)

1994-06-01

The Department of Energy study examines the effects of lifting the current prohibitions against the export of Alaskan North Slope (ANS) crude. The study concludes that permitting exports would benefit the US economy. First, lifting the ban would expand the markets in which ANS oil can be sold, thereby increasing its value. ANS oil producers, the States of California and Alaska, and some of their local governments all would benefit from increased revenues. Permitting exports also would generate new economic activity and employment in California and Alaska. The study concludes that these economic benefits would be achieved without increasing gasoline prices (either in California or in the nation as a whole). Lifting the export ban could have important implications for US maritime interests. The Merchant Marine Act of 1970 (known as the Jones Act) requires all inter-coastal shipments to be carried on vessels that are US-owned, US-crewed, and US-built. By limiting the shipment of ANS crude to US ports only, the export ban creates jobs for the seafarers and the builders of Jones Act vessels. Because the Jones Act does not apply to exports, however, lifting the ban without also changing US maritime law would jeopardize the jobs associated with the current fleet of Jones Act tankers. Therefore the report analyzes selected economic impacts of several maritime policy alternatives, including: Maintaining current law, which allows foreign tankers to carry oil where export is allowed; requiring exports of ANS crude to be carried on Jones Act vessels; and requiring exports of ANS crude to be carried on vessels that are US-owned and US-crewed, but not necessarily US-built. Under each of these options, lifting the export ban would generate economic benefits.

Directory of Open Access Journals (Sweden)

Elena Vladimirovna Sapir

2016-12-01

Full Text Available This article analyzes a diverse range of the enterprise’s export potential growth factors in emerging pharmaceutical clusters of Central European Russia. Classification and comparative analysis were used to identify export potential attributes (production, finance, labor and marketing, which have allowed to reveal the strong connection of cluster and regional factor groups with the results of export performance. The purpose of the study is to provide exports-seeking pharmaceutical companies with a set of tools to enhance their export potential. The hypothesis that the cumulative impact of the specified attributes leads to the strengthening of pharmaceutical cluster export potential and promotes an effective integration of the region in the world economic space, is developed and tested. The methodology combines the geo-economy-based theory with the theory of clusters competitive advantages. The impacts of export potential growth factors are estimated by using an econometric model based on math statistics. Thus, five Russian regional pharmaceutical clusters (Belgorod, Kaluga, Moscow, Oryol, Yaroslavl are shown. Findings identify an objective causal link between enterprise export potential growth and competitiveness factors of cluster origin (network business chains, production functions interconnectedness and flexibility, production localization. An action plan for the purpose of the maximum use of competitive advantages of the cluster organization for export activities of the entities of the pharmaceutical industry is developed. Conclusions and recommendations of the study are intended to enterprises in pharmaceutical industry and regions’ public authorities, implementing cluster development strategies. It is thus essential to improve marketing and organizational innovations, reduction of commercial expenses under the cluster environment, development of drugs production and delivery chains from R&D to end-users in order to enjoy greater

The Impact of Export Dynamics on a Firm’s Growth

Jerzy Cieślik

2014-09-01

Full Text Available Purpose: This research aimed to identify the prevalence and particular characteristics of export-driven growth as opposed to those of the domestic market. It examined how the relative dynamics of export sales vs. domestic sales were affected by internationalization intensity (FSTS, age of the fi rm, early internationalization, size of the fi rm and industry technological level. Similarly, it examined the impact of sales growth and its direction (domestic vs. export-driven on company performance. Methodology: The analysis was based on panel data from approximately 300 manufacturing fi rms in the Mazovia region of Poland that were engaged in sustained export operations during 2003 to 2010. Several hypotheses were tested regarding factors affecting the growth dynamics of regular exporters as well as their performance (productivity. Findings: This research proved that only a small percentage (less than 10% of fi rms reached the status of regular exporter, although regular exporters engaged in international operations shortly after their foundation, They formed a distinct category of early internationalizing firms. For the management of young, ambitious ventures, achieving regularity in their initial export operations represented a major challenge. Implications: Regularity of international sales is crucial for export performance, both at the enterprise and country levels. This implies that export promotion efforts should concentrate on growth-oriented fi rms, specifi cally to assist them in reaching regular exporter status shortly after initiating sales outside the domestic market. Originality: The analysis of the internationalization process was expanded by adding the regularity dimension,which has been rarely addressed in the extant literature.

Canadian electricity exports and imports : an energy market assessment

International Nuclear Information System (INIS)

2003-01-01

This energy market assessment (EMA) report focuses on recent trends in exports and imports of Canadian electricity and the associated revenue and pricing. It also outlines major developments in electricity markets in Canada and the United States in the past decade with reference to the implications of electricity trade for both consumers and the power industry. This guide comes at a time of market openings in Alberta and Ontario, and with recent increases in applications to the National Energy Board for electricity exports and international power lines. The first chapter presents an overview of current Canadian federal regulatory regime for electricity exports and restructuring of the electric power industry in Canada and the United States. The second chapter reviews electricity exports and imports from a national perspective. Provincial analyses were presented in the third chapter which also covered international interconnections, export and import trends, export and import pricing, implications for consumer prices, and factors affecting future trade. The final chapter presents some observations on each of these issues. It is noted that exports have fluctuated significantly from year to year due to specific events including the shutdown of nuclear power plants, high gas prices, and the California electricity crisis in 2000-2001. Canadian international electricity trade has continued to yield net revenues of $1 to $2 billion per year due to strong electricity export prices. The relationship between export and import prices varies from province to province. Canadian utilities have emphasized the need for more transmission to the U.S. to foster future trade and improve transmission reliability. refs., tabs., figs

Vang, Jan; Baklanov, Nikita; Rezaei, Shahamak

Recent studies on transnational entrepreneurship) suggest that migrant entrepreneur play an increasingly significant role as sources of economic activities and especially export revenue. The literature is, however, biased on the US experience, lacks a comparative perspective between migrants...... and non-migrants and is primarily anecdotal in nature (Saxenian, 2002; 2006, Ruzzlier et al, 2007; Honig and Drori, 2010, Drodi et al, 2010)). This paper aims at reducing this gap by mapping the recent changes in the role of migrant entrepreneurs as a source of increased economic activity and export...... in across ethic categories. Export revenue is proxied by the number of firms in the different ethnic categories that exports. The Danish context provides unique data allowing for a comparison across migrants and non-migrants, across sectors and across time. The paper reveals that migrants play a decreasing...

The orphan nuclear receptor NR4A1 (Nur77) regulates oxidative and endoplasmic reticulum stress in pancreatic cancer cells.

NR4A1 (Nur77, TR3) is an orphan nuclear receptor that is overexpressed in pancreatic cancer and exhibits pro-oncogenic activity. RNA interference of NR4A1 expression in Panc-1 cells induced apoptosis and subsequent proteomic analysis revealed the induction of several markers of endoplasmic reticulum stress, including glucose-related protein 78 (GRP78), CCAAT/enhancer-binding protein-homologous protein (CHOP), and activating transcription factor-4 (ATF-4). Treatment of pancreatic cancer cells with the NR4A1 antagonist 1,1-bis(3'-indolyl)-1-(p-hydroxyphenyl)methane (DIM-C-pPhOH) gave similar results. Moreover, both NR4A1 knockdown and DIM-C-pPhOH induced reactive oxygen species (ROS), and induction of ROS and endoplasmic reticulum stress by these agents was attenuated after cotreatment with antioxidants. Manipulation of NR4A1 expression coupled with gene expression profiling identified a number of ROS metabolism transcripts regulated by NR4A1. Knockdown of one of these transcripts, thioredoxin domain containing 5 (TXNDC5), recapitulated the elevated ROS and endoplasmic reticulum stress; thus, demonstrating that NR4A1 regulates levels of endoplasmic reticulum stress and ROS in pancreatic cancer cells to facilitate cell proliferation and survival. Finally, inactivation of NR4A1 by knockdown or DIM-C-pPhOH decreased TXNDC5, resulting in activation of the ROS/endoplasmic reticulum stress and proapoptotic pathways. The NR4A1 receptor is pro-oncogenic, regulates the ROS/endoplasmic reticulum stress pathways, and inactivation of the receptor represents a novel pathway for inducing cell death in pancreatic cancer.

One approach to improving the competitiveness of photovoltaic systems is the development of designs specifically for export applications. In other words, where is it appropriate in a system design to incorporate components manufactured and/or assembled in the receiving country in order to improve the photovoltaic exports from the US? What appears to be needed is a systematic method of evaluating the potential for export from the US of PV systems for various application in different countries. Development of such a method was the goal of this project.

Analysis of Fiji’s Export and Its Impact on Economic Growth

Directory of Open Access Journals (Sweden)

Shivneil Kumar Raj

2017-05-01

Full Text Available Exports are vital for Fiji’s economy as it contributes significantly to its gross domestic product (GDP and economic growth. The export data over the years show very slow growth and is gradually increasing. Fiji’s GDP data show that GDP is gradually increasing. Thus, Fiji’s economic growth is also increasing at a steady rate. This study aims to measure the relationship between exports and economic growth in Fiji. A regression analysis on data collected for Fiji from 2000-2015 shows that there is a strong positive relationship between exports and economic growth. Thus, when exports increase, economic growth also increases. Potential sectors that can be further developed to boost Fiji’s exports are sugar, garment, tourism and agriculture. The government should restrict imports through import quotas, tariffs and embargoes and give subsidies and tax incentives to potential export sectors to boost domestic production and increase exports. The government’s motive is to increase export incentives and promote Fiji made products both locally and overseas. Thus, this leads to an increase in exports, improves the trade balance and economic growth. This research article was undertaken to carry out research to investigate the link between Fiji’s export and economic growth and highlight ways and potential sectors to increase Fiji’s export and reduce imports.

Here, we have analyzed the subcellular destiny of newly synthesized tight junction protein zona occludens (ZO)-2. After transfection in sparse cells, 74% of cells exhibit ZO-2 at the nucleus, and after 18 h the value decreases to 17%. The mutation S369A located within the nuclear exportation signal 1 of ZO-2 impairs the nuclear export of the protein. Because Ser369 represents a putative protein kinase C (PKC) phosphorylation site, we tested the effect of PKC inhibition and stimulation on the nuclear export of ZO-2. Our results strongly suggest that the departure of ZO-2 from the nucleus is regulated by phosphorylation at Ser369 by novel PKCepsilon. To test the route taken by ZO-2 from synthesis to the plasma membrane, we devised a novel nuclear microinjection assay in which the nucleus served as a reservoir for anti-ZO-2 antibody. Through this assay, we demonstrate that a significant amount of newly synthesized ZO-2 goes into the nucleus and is later relocated to the plasma membrane. These results constitute novel information for understanding the mechanisms that regulate the intracellular fate of ZO-2.

Electrons without borders: legal issues in exporting power

International Nuclear Information System (INIS)

Atcheson, Aaron

2011-01-01

Miller Thomson LLP provides a range of personal and business law legal services to a variety of projects, particularly those involving renewable energy generation. This paper discusses the legal issues the company has faced in exporting power. There are three ways to export electricity, sale of environmental attributes/carbon credits across borders, via existing transmission facilities and via new transmission facilities. Authorizations by the relevant provincial entity are required to export via the existing transmission. To export power across into the US, permission is needed from both the National Energy Board (NEB) and from the US authorities. The history and the process of obtaining this permission through the NEB are discussed in detail. The approvals and considerations necessary to transport power through new transmission facilities and sale of environmental attributes are given in detail. The paper concludes that a special project is needed with unique opportunities to make the export of power the destination for all production.

HMGB1 induces an inflammatory response in endothelial cells via the RAGE-dependent endoplasmic reticulum stress pathway

Luo, Ying; Li, Shu-Jun; Yang, Jian; Qiu, Yuan-Zhen; Chen, Fang-Ping

2013-01-01

Highlights: •Mechanisms of inflammatory response induced by HMGB1 are incompletely understood. •We found that endoplasmic reticulum stress mediate the inflammatory response induced by HMGB1. •RAGE-mediated ERS pathways are involved in those processes. •We reported a new mechanism for HMGB1 induced inflammatory response. -- Abstract: The high mobility group 1B protein (HMGB1) mediates chronic inflammatory responses in endothelial cells, which play a critical role in atherosclerosis. However, the underlying mechanism is unknown. The goal of our study was to identify the effects of HMGB1 on the RAGE-induced inflammatory response in endothelial cells and test the possible involvement of the endoplasmic reticulum stress pathway. Our results showed that incubation of endothelial cells with HMGB1 (0.01–1 μg/ml) for 24 h induced a dose-dependent activation of endoplasmic reticulum stress transducers, as assessed by PERK and IRE1 protein expression. Moreover, HMGB1 also promoted nuclear translocation of ATF6. HMGB1-mediated ICAM-1 and P-selectin production was dramatically suppressed by PERK siRNA or IRE1 siRNA. However, non-targeting siRNA had no such effects. HMGB1-induced increases in ICAM-1 and P-selectin expression were also inhibited by a specific eIF2α inhibitor (salubrinal) and a specific JNK inhibitor (SP600125). Importantly, a blocking antibody specifically targeted against RAGE (anti-RAGE antibody) decreased ICAM-1, P-selectin and endoplasmic reticulum stress molecule (PERK, eIF2α, IRE1 and JNK) protein expression levels. Collectively, these novel findings suggest that HMGB1 promotes an inflammatory response by inducing the expression of ICAM-1 and P-selectin via RAGE-mediated stimulation of the endoplasmic reticulum stress pathway

Increases in nitrogen (N) availability and mobility resulting from anthropogenic activities has substantially altered N cycle both locally and globally. Taiwan characterized by the subtropical montane landscape with abundant rainfall, downwind to the most rapidly industrializing east coast of China can be a demonstration site for extreme high N input and riverine DIN (dissolved inorganic N) export. We used 49 watersheds classified into low-, moderate-, and highly-disturbed categories based on population density to illustrate their differences in nitrogen inputs through atmospheric N deposition, synthetic fertilizers and human emission and DIN export ratios. Our results showed that the island-wide average riverine DIN export is ~ 3800 kg N km-2 yr-1, approximately 18-fold higher than the global average mostly due to the large input of synthetic fertilizers. The average riverine DIN export ratio is 0.30-0.51, which is much higher than the average of 0.20-0.25 of large rivers around the world indicating excessive N input relative to ecosystem demand or retention capacity. The low-disturbed watersheds, despite of high N input, only export 0.06-0.18 of the input so were well buffered to changes in input quantity suggesting high efficiency of nitrogen usage or high N retention capacity of the less disturbed watersheds. The high retention capacity probably is due to the effective uptake by secondary forests in the watersheds. The moderate-disturbed watersheds show a linear increase of output with increases in total N inputs and a mean DIN export ratio of 0.20 to 0.31. The main difference in land use between low and moderately disturbed watershed is the relative proportions of agricultural land and forests, not the built-up lands. Thus, their greater DIN export quantity could be attributed to N fertilizers used in the agricultural lands. The greater export ratios also imply that agricultural lands have lower proportional N retention capacity and that reforestation could be

Russian crude-oil production and export still increasing

International Nuclear Information System (INIS)

Purho, P.

2001-01-01

Russian crude-oil production is still increasing. In 2000 the annual production 6.48 mb/d was about 6% higher than a year before. In 2001 the production is expected to rise near the level 7 mb/d, so the increase in production volume is fast. However, the production is still far away from the maximum level of the former Soviet Union, 12 mb/d. At the moment Russia is the second largest oil producer right after Saudi Arabia. The increase in production is based on intensified use of old oil fields caused by improved technology. The oil export of Russia far abroad in 2000 was 2.5 mb/d and near abroad into FSU countries only about 180 000 b/d. The recent export of crude-oil has been near the maximum export capacity corresponding to 2.7 mb/d. About 61 million tons of oil products were exported in 2000, and even the export of oil products is increasing. Most of this was gas oil and heavy fuel oil, but also the export of gasoline was significant. The export of oil and oil products is mainly based on shipments, but also the share of train transport is high. Nearly all the crude oil is transported west either by ships or via pipelines. The share of railway transport is only few percents. Russia will continue its own oil pumping policy despite of the appeals of OPEC for reduction of oil production. Opinion in Russia is that if the increase of production and export serves the interests of Russia, it will also be carried out. The target value for crude oil for 2002 is 22 USD per barrel. The Russian crude oil production is estimated to grow up to 7.4 - 8.4 mb/d by the year 2010

Power exports - a U.S. market for CANDU (question mark)

McIntyre, H.C.

1982-01-01

The advantages to both countries of power exports from Canada to the U.S.A. are explained. The policy of the Canadian federal government now tends to favour such exports. While Hydro-Quebec leads in exports, Ontario Hydro plans to sell 1.2 GW of coal-generated power to New Jersey. New Brunswick now has applications before the National Energy Board for export of 0.35 GW from Point Lepreau. A second 0.6 GW unit at Point Lepreau, dedicated to the export of electricity, has been suggested

The unfolded protein response (UPR) handles unfolded/misfolded proteins accumulated in the endoplasmic reticulum (ER). However, it is unclear how vertebrates correctly use the total of ten UPR transducers. We have found that ER stress occurs physiologically during early embryonic development in medaka fish and that the smooth alignment of notochord cells requires ATF6 as a UPR transducer, which induces ER chaperones for folding of type VIII (short-chain) collagen. After secretion of hedgehog for tissue patterning, notochord cells differentiate into sheath cells, which synthesize type II collagen. In this study, we show that this vacuolization step requires both ATF6 and BBF2H7 as UPR transducers and that BBF2H7 regulates a complete set of genes (Sec23/24/13/31, Tango1, Sedlin, and KLHL12) essential for the enlargement of COPII vesicles to accommodate long-chain collagen for export, leading to the formation of the perinotochordal basement membrane. Thus, the most appropriate UPR transducer is activated to cope with the differing physiological ER stresses of different content types depending on developmental stage. PMID:28500182

Studies have shown that the economy of Ghana cannot afford to rely solely on cocoa exports. It is imperative to diversify the export base of the Ghanaian economy. In this respect, the palm oil sub-sector of the agricultural sector, which until the early part of the 20th century was the major agricultural export commodity of Ghana, needs to be considered for promotion. Currently the palm oil industry faces the challenge of bleak export potential. This study examines trends in the quantity expo...

Ricin A chain reaches the endoplasmic reticulum after endocytosis

Liu Qiong; Zhan Jinbiao; Chen Xinhong; Zheng Shu

2006-01-01

Ricin is a potent ribosome inactivating protein and now has been widely used for synthesis of immunotoxins. To target ribosome in the mammalian cytosol, ricin must firstly retrograde transport from the endomembrane system to reach the endoplasmic reticulum (ER) where the ricin A chain (RTA) is recognized by ER components that facilitate its membrane translocation to the cytosol. In the study, the fusion gene of enhanced green fluorescent protein (EGFP)-RTA was expressed with the pET-28a (+) system in Escherichia coli under the control of a T7 promoter. The fusion protein showed a green fluorescence. The recombinant protein can be purified by metal chelated affinity chromatography on a column of NTA. The rabbit anti-GFP antibody can recognize the fusion protein of EGFP-RTA just like the EGFP protein. The cytotoxicity of EGFP-RTA and RTA was evaluated by the MTT assay in HeLa and HEP-G2 cells following fluid-phase endocytosis. The fusion protein had a similar cytotoxicity of RTA. After endocytosis, the subcellular location of the fusion protein can be observed with the laser scanning confocal microscopy and the immuno-gold labeling Electro Microscopy. This study provided important evidence by a visualized way to prove that RTA does reach the endoplasmic reticulum

Intermediation in Foreign Trade: When do Exporters Rely on Intermediaries?

DEFF Research Database (Denmark)

Schröder, Philipp; Trabold, Harald; Trübswetter, Parvati

2003-01-01

The paper explores theoretically and empirically why trade intermediaries (TIs) are frequently used as agents for exports to some countries but not to others. We adapt a standard intra-industry trade model with variable export costs (e.g. transport) and fixed export costs (e.g. market access......) to include a TI that is able to pool market access cost. From this framework explanatory factors for the TI share in a country's exports are derived and subsequently tested with a new data set based on French customs information. The paper finds that: (i) higher market access costs increase the TI share, (ii......) smaller export markets feature a larger TI share, (iii) the TI share is independent from variable (distance-dependent) export costs....

Sudanese live sheep and mutton exports competitiveness

Directory of Open Access Journals (Sweden)

Babiker Idris Babiker

2011-01-01

Full Text Available The livestock sector of Sudan provides livelihood for about 17% of the population. Sudanese livestock products meet the domestic demand for meat in addition to a substantial excess for export amounting to about 22% of total country exports. It contributes about 19% of GDP. Sheep marketing in Sudan is characterised by traditional operations and is informally organised, although, recently there are great efforts by the formal livestock authorities to organise some secondary and terminal livestock markets. These markets are deficient in basic infrastructures and systematic marketing research. The system as a whole is faced by various complex obstacles and constraints, which decrease the contribution of livestock in general, and sheep in particular, to the national economy, and suppress the optimum exploitation of this resource. These obstacles are represented in the lack of transportation networks that connect the production and consumption centres to break the seasonality of supply that creates shortages and high prices at the consumption centres. This paper employs the policy analysis matrix (PAM technique to examine the Sudanese live sheep and mutton competitiveness in the international market. The results indicated that the market price was greater than the border price implying a positive incentive as an implicit subsidy to the live sheep exporter. The mutton exporters were found subsidised as well. The international value added (IVA indicted a positive foreign exchange earnings or savings. Exported live sheep and mutton coefficient of competitiveness (CIC implied that sheep and mutton exports are profitable and internationally competitive.

Increases in nitrogen (N) availability and mobility resulting from anthropogenic activities have substantially altered the N cycle, both locally and globally. Taiwan characterized by the subtropical montane landscape with abundant rainfall, downwind of the most rapidly industrializing eastern coast of China, can be a demonstration site for extremely high N input and riverine DIN (dissolved inorganic N) export. We used 49 watersheds with similar climatic and landscape settings but classified into low, moderate, and highly disturbed categories based on population density to illustrate their differences in nitrogen inputs (through atmospheric N deposition, synthetic fertilizers, and human emission) and DIN export ratios. Our results showed that the island-wide average riverine DIN export is ˜ 3800 kg N km-2 yr-1, approximately 18 times the global average. The average riverine DIN export ratios are 0.30-0.51, which are much higher than the averages of 0.20-0.25 of large rivers around the world, indicating excessive N input relative to ecosystem demand or retention capacity. The low disturbed watersheds have a high N retention capacity and DIN export ratios of 0.06-0.18 in spite of the high N input (˜ 4900 kg N km-2 yr-1). The high retention capacity is likely due to effective uptake by secondary forests in the watersheds. The moderately disturbed watersheds show a linear increase in DIN export with increases in total N inputs and mean DIN export ratios of 0.20 to 0.31. The main difference in land use between low and moderately disturbed watersheds is the greater proportion of agricultural land cover in the moderately disturbed watersheds. Thus, their greater DIN export could be attributed to N fertilizers used in the agricultural lands. The greater export ratios also imply that agricultural lands have a lower proportional N retention capacity and that reforestation could be an effective land management practice to reduce riverine DIN export. The export ratios of the

Leber's hereditary optic neuropathy (MIM#535000), the commonest mitochondrial DNA-related disease, is caused by mutations affecting mitochondrial complex I. The clinical expression of the disorder, usually occurring in young adults, is typically characterized by subacute, usually sequential, bilateral visual loss, resulting from the degeneration of retinal ganglion cells. As the precise action of mitochondrial DNA mutations on the overall cell metabolism in Leber's hereditary optic neuropathy is unknown, we investigated the metabolomic profile of the disease. High performance liquid chromatography coupled with tandem mass spectrometry was used to quantify 188 metabolites in fibroblasts from 16 patients with Leber's hereditary optic neuropathy and eight healthy control subjects. Latent variable-based statistical methods were used to identify discriminating metabolites. One hundred and twenty-four of the metabolites were considered to be accurately quantified. A supervised orthogonal partial least squares discriminant analysis model separating patients with Leber's hereditary optic neuropathy from control subjects showed good predictive capability (Q 2cumulated = 0.57). Thirty-eight metabolites appeared to be the most significant variables, defining a Leber's hereditary optic neuropathy metabolic signature that revealed decreased concentrations of all proteinogenic amino acids, spermidine, putrescine, isovaleryl-carnitine, propionyl-carnitine and five sphingomyelin species, together with increased concentrations of 10 phosphatidylcholine species. This signature was not reproduced by the inhibition of complex I with rotenone or piericidin A in control fibroblasts. The importance of sphingomyelins and phosphatidylcholines in the Leber's hereditary optic neuropathy signature, together with the decreased amino acid pool, suggested an involvement of the endoplasmic reticulum. This was confirmed by the significantly increased phosphorylation of PERK and eIF2α, as well as

Cointegration and Causality Test Among Export, Import, and Foreign Exchange

Haryono Subiyakto

2016-06-01

Full Text Available The rupiah exchange rate, import, and export are the important indicators in economy, including the Indonesia economy. The debate regarding the relationship among the exchange rate, import, and export has been persisting for several decades. Some researchers found that there is a relationship among those three and others explained that there is no correlation among them. The aim of this research is to obtain the empirical evidence of the causal relationship among the export, import, and foreign exchange rate by using the monthly data from January 2010 to April 2014. The export and import data are the export and import values in US dollar. The exchange rate data is the median exchange rates of the Indonesian Bank. The Johansen Cointegration Test and the Granger Causality Test are used to analyze the data. The research result shows that export and import have no causal relationship at five percent. Next, the foreign exchange rate influences the export and import at 10 percent level. The result indicates that the foreign exchange rate has small effects on the export and import. Based on the results, the government should control the balance of trade and should not make any policy that is based on the exchange rate values. Finally, it can be said that the exchange rate policy is not effective in increasing the exports and reducing the imports.

In-Kind Export Subsidies for Processed and Bulk Goods

This research analyzes the interaction between a bulk commodity and a processed good under in-kind export subsidies. An in-kind export subsidy lowers the export price of the good on which it is paid. The other price changes are ambiguous. A numerical model for U.S. wheat and flour illustrates these conditions. Given the parameters of the model, an in-kind payment using wheat lowers flour prices and the export price of wheat. The U.S. domestic wheat price rises. When flour is used for the paym...

Marketing technologies for building competitiveness of companies export

Full Text Available In context of post-industrial development of global economy, escalating competition in international goods markets, the definition of competitive export is proposed based upon both existing criteria – sustainability, effectiveness, adaptivity and fair competition, and on those described in the work – ecological performance, service maintenance, brand awareness and high technology. Given that, it is proved that with the aim of detailing the elements of competitive export, the latter should be typified depending upon the performer (export competitiveness of a company, country, region and subject (export competitiveness of goods, services, rights upon intellectual property objects, keeping in mind universal and specific features of export criteria proposed to be characterised through a range of indices on corporate and state levels. Groups of factors affecting export competitiveness building are systematized (institutional, financial and economic, marketing, foreign trade, scientific and technological, resource-related and social and ecological. Marketing technologies are typified on corporate level under the following criteria: novelty, object, creative component availability, internationalization stages, international marketing forms, digitalization level, management functions, customer-centreness scale, international marketing activity stages, financial security, specific features of intercorporate coordination. The practice of applying international marketing technologies by companies is investigated. In context of necessity to overcome crisis phenomena and increase competitive export volume, an assessment is made of integrating national manufacturing into regulated global chains of creating added value with the relevant rating, in particular, depending upon the available potential, minimality of technical and organizational changes, marketing relevancy, enabling to determine the manufacturing areas most prepared to cooperation, and

2015-12-01

Full Text Available The purpose of this article is to evaluate the effect of distance on the export performance of companies in Santa Catarina, and to what extent this effect is moderated by organizational resource characteristics. Multiple linear regression and variance analysis were used for a perception survey of export managers with a final sample of 49 exporting producers. The constructs showed internal validity and allowed the data to be analyzed. The results only revealed evidence regarding the effect of psychic distance, showing a positive relationship with export performance. Also, the model estimation showed that the organization's resources moderate the relation between distance and export performance. Finally the study also shows that the export team and the organizational structure moderate the effect of distance on the performance and future performance expectations of the companies.

Russian gas exports have potential to grow through 2020

International Nuclear Information System (INIS)

Fernandez, Rafael

2009-01-01

This paper analyzes the potential for Russian gas export growth through the next decade and concludes that supply for exports will continue to grow, albeit moderately. The greater or lesser intensity of that growth will depend on the evolution of both production and internal consumption. From the production side, the pace of growth depends on the status of gas reserves and, more importantly, on the investment program pursued by the State-owned gas giant Gazprom. From the demand side, evolution depends on the way Russia's wide potential for gas savings is managed. Through this analysis, we find three likely scenarios for Russian gas exports. In the most positive, diversification of exports will be possible. In the most negative, Russia will have scant opportunity to develop an export diversification strategy.

Coudray, M.; Perrais, J.P.

1976-01-01

Safety problems arising from exportation are especially handled through the French exportation of PWR stations. Regulations differ widely from one country to another. However, very large use of American regulations is made and frequently there is a tendency to harden such or such clause in the quotation. Industry must be ready to give satisfaction to such demands of customers. Sometimes also, it is a mere duplication of French stations which is above all looked for. In that case, it is the problem of using French regulations abroad which arises. Desirable changes in examination proceedings are analyzed together with a French regulation effort aiming to make easier the promotion of their use abroad. Finally, safety may be a factor of success for exportation attempts. It is shown how useless some outbiddings may be, but also how, on the contrary, speeding up of research and development effort towards specific safety problems in case of exportation, is to be promoted [fr

Is Mercosur promoting trade? Insights from Argentinean wine exports

2017-09-01

As a consequence of the rapid and significative decrease in domestic demand, to avoid structural surplus traditional wine producing countries have been forced to export a growing share of their wine production. This article empirically investigates Argentinean trade policy on the wine sector over the last years, in order to understand its effect on export flows. An expanded gravity model was estimated through a Poisson pseudo-maximum likelihood estimator, in order to account for heteroskedasticity. The data used refer to Argentinean exports of bottled wine to all main world importers during the period 1997-2010, and account for more than 90% of total trade flows. Our results show that Mercosur membership has promoted Argentinean wine exports to other Latin American countries, but may as a whole have been counter-productive. A more open trade policy could increase Argentinean bottled wine exports by more than 5.8%. In addition, given the rise in wine importation and consumption in countries with high tariff barriers, such as China, the small number of free trade agreements could penalize Argentinean exports even more in the future.

To decompose uncertainties into two types of component, I propose an advanced generalized Markov switching model, as developed by Hamilton (1989 and then expanded by Kim and Kim (1996. The proposed model is useful in uncovering two sources of uncertainty: the permanent component of REER and the purely transitory component. I think that the two types of uncertainties have a different effect on export trends in Korea. The transitory component of REER has no effect on the export trend at 5-percent significance, but the permanent component has an effect at this level. In addition, the degree of uncertainty, consisting of low, medium and high uncertainty in the permanent component, and low, medium and high uncertainty in transitory component of REER, also has different effects on export trends in Korea. Only high uncertainty in permanent components effects export trends. The results show that when the policy authority intends to prevent the shrinkage of exports due to the deepening of uncertainties in the foreign exchange market, the economic impacts of its intervention could appear differently according to the characteristics and degree of the uncertainties. Therefore, they imply that its economic measures, which could not grasp the sources of uncertainties properly, may even bring economic costs.

Export of protein-coding and non-coding RNA molecules from the nucleus to the cytoplasm is critical for gene expression. This necessitates the continuous transport of RNA species of different size, shape and function through nuclear pore complexes via export receptors and adaptor proteins. Here, we provide an overview of the major RNA export pathways in humans, highlighting the similarities and differences between each. Its importance is underscored by the growing appreciation that deregulation of RNA export pathways is associated with human diseases like cancer. Crown Copyright © 2017. Published by Elsevier Ltd.
