Reforming the Multilateral Export Control Regimes
The use of export controls to regulate the supply of major conventional arms systems and materials associated with weapons of mass destruction (WMD) has long been a central component of nonproliferation efforts. But how well are US and multilateral efforts to control the export of advanced weaponry and sensitive dual-use technologies working? Iraq’s ability to purchase key components for its WM...
متن کاملControl of chylomicron export from the intestine.
The control of chylomicron output by the intestine is a complex process whose outlines have only recently come into focus. In this review we will cover aspects of chylomicron formation and prechylomicron vesicle generation that elucidate potential control points. Substrate (dietary fatty acids and monoacylglycerols) availability is directly related to the output rate of chylomicrons. These subs...
متن کاملOptogenetic control of nuclear protein export
Active nucleocytoplasmic transport is a key mechanism underlying protein regulation in eukaryotes. While nuclear protein import can be controlled in space and time with a portfolio of optogenetic tools, protein export has not been tackled so far. Here we present a light-inducible nuclear export system (LEXY) based on a single, genetically encoded tag, which enables precise spatiotemporal contro...
متن کاملOpen source information for export control
This paper presents some preliminary work in the area of export control for nuclear proliferation. The long term goal is to access and analyse data that may relate to the trade of nuclear dual-use items and technologies: this data is available through various open sources. The immediate goal is to work on a table of correspondence between codes that describe, on one side, nuclear items and the ...
متن کاملEarly formation of mRNP: license for export or quality control?
Eukaryotic mRNA is processed by enzymes and packaged with proteins within nuclei to generate functional messenger ribonucleoprotein (mRNP) particles. Processing and packaging factors can interact with mRNA cotranscriptionally to form an early mRNP. Erroneous mRNP formation leads to nuclear retention and degradation of the mRNA. It therefore appears that one function of cotranscriptional mRNP as...
