The sharp increase in Australia's terms of trade since 2003-04 has dramatic regional and sectoral implications. Mining-intensive regions have gained from the jump in export prices. Import-competing sectors have faced greater competition both from falling import prices and due to rising demand for domestic factors from the mining sectors. The drought of 2006 will widen the gap between winning an...

We previously demonstrated that subsarcolemmal (SS) and intermyofibrillar (IMF) mitochondrial subfractions import proteins at different rates. This study was undertaken to investigate 1) whether protein import is altered by chronic contractile activity, which induces mitochondrial biogenesis, and 2) whether these two subfractions adapt similarly. Using electrical stimulation (10 Hz, 3 h/day for...

Nuclear import of the four core histones H2A, H2B, H3 and H4 is one of the main nuclear import activities during S-phase of the cell cycle. However, the molecular machinery facilitating nuclear import of core histones has not been elucidated. Here, we investigated the pathways by which histone import can occur. First, we show that core histone import can be competed by the BIB (beta-like import...

one of the main principles of resistance economy, is to support domestic production and limiting imports, especially in sectors where there is the possibility of import-substituting production .this requires adjustment of exact trade policies,and to achieve this, identifying the structure of imports demand function and also price and income elasticity of import demand is necessary.this necessit...

Most peroxisomal matrix proteins possess a carboxy-terminal tripeptide targeting signal, termed peroxisomal targeting signal type 1 (PTS1), and follow a relatively well-characterized pathway of import into the organelle. The peroxisomal targeting signal type 2 (PTS2) pathway of peroxisomal matrix protein import is less well understood. In this study, we investigated the mechanisms of PTS2 prote...

H(2)O(2) alters gene expression in many cell types. Alterations in nuclear import of transcription factors or similar key proteins may be responsible for these changes. To investigate this possibility, a cytosolic nuclear import cocktail was treated with varying ¿H(2)O(2) and used in import assays. H(2)O(2) caused a dose- and time-dependent inhibition of import at concentrations as low as 100 m...

Estimating the price elasticity of China’s imports is difficult because many imports are used to produce exports and because the real effective exchange rate has remained fairly stable. To circumvent the first problem, we control for re-exports, and to increase the discriminatory power of the tests, we employ a panel data set including imports from 25 countries. The results indicate that a 10 p...

We established a straightforward experimental system to investigate directly the requirements for nucleocytoplasmic transport in live cells. For this purpose, substrates were created containing nuclear localization signals (NLS) or nuclear export signals (NES) linked to a chimeric protein composed of the glutathione S-transferase (GST) fused to the green fluorescent protein (GFP). The combinati...

foreign trade of any country is considered as one of the major economic sectors of that society as far as some refer to trade as the “engine of growth”. foreign exchange rate and its volatilities is one of the effective factors determining foreign trade. the present paper deals with the impact of real exchange rate uncertainty on imports in iran during 1979-2009. in this respect, first, among v...
