Optical single-transporter recording, a recently established fluorescence microscopic method, was used to study the selective transport of proteins through single nuclear pore complexes (NPCs) of Xenopus oocytes. Recombinant proteins containing either a nuclear localization signal (import protein) or a nuclear export signal (export protein) were generated as transport substrates. To approximate...

this paper analyzes the effects ofexchange policies on iran,s foreign trade, by applying new econometric techniques. in assessing the impacts of depreciation of the national currency on macroeconomic variable, the real rather than nominal exchange rate has been determined to be more appropriate criterion to demonstrate the success or failure ofthe adopted policies. during the period under the s...

Outward direct investment (ODI) from the People’s Republic of China (PRC) is surging. A common perception is that it was driven by the country’s resourceseeking and technology-seeking motives. Using a new, unique, and comprehensive dataset that covers close to 10,000 Chinese ODI deals from 1998 to 2009, we find that in contrast to the common perception, over half of the ODI deals are in service...

The paper deals with the commodity flows (production, import, export, consumption, prices) of manganese, chromium, silicon, vanadium, niobium, molybdenum, tungsten, titanium and nickel ferroalloys in dynamics from 2000 to 2019 throughout Russia. also specifies groups ferroalloys: import-dependent (silicomanganese, metallic ferroniobium), export-oriented (ferrosilicon, ferrochrome, ferrovanadium...

BACKGROUND At M phase, cyclin B1 is phosphorylated in the cytoplasmic retention sequence (CRS), which is required for nuclear export. During interphase, cyclin B1 shuttles between the nucleus and the cytoplasm because constitutive nuclear import is counteracted by rapid nuclear export. In M phase, cyclin B moves rapidly into the nucleus coincident with its phosphorylation, an overall movement t...
