The objective of the present study was to perform a meta-analysis of all available studies on the effect of prophylactic ulinastatin administration on preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). The PubMed, Web of Knowledge and Chinese National Knowledge Infrastructure databases were searched to identify all relevant studies published in English or ...

This article presents findings from the first large-scale quantitative assessment of Peer-to-Peer (P2P) exchanges of copyrighted material on a college campus based on actual observation. Through passive monitoring and deep packet inspection (DPI), we assess the extent to which P2P is used to transfer copyrighted material. We also characterize the demographics of P2P users, the relative populari...

Inhibition efficiencies of three amine derivatives (Diethylenetriamine (I), Triethylenetetramine (II), and Pentaethylenehexamine (III)) have been studied on corrosion of carbon steel using density functional theory (DFT) method in gas phase. Quantum chemical parameters such as EHOMO (highest occupied molecular orbital energy), ELUMO (lowest unoccupied molecular orbital energy), hardness (η), po...

Pollution with oil spills, a major contributor to water contamination, has remarkable effect on the economy, biodiversity, and environment. To protect marine species environment, efforts should be undertaken for developing efficient ways remove spills. The current work discusses spill removal using magnetite nanoparticles (MNPs) functionalized hydrophobic polyethyleneimine (HPEA). In this respe...

The isolation of 3,6,9,12-tetraazatetradecane-l,14-diamine (linear isomer of pentaethylene­ hexamine, linpen) from a technical polyamine mixture is described. In methanol, linpen acts as a hexadentate ligand towards cadmium(II). The solid compounds [Cd(linpen)](BPh4)2 (1), [Cd(linpen)](BPh4)2-2DM SO (2) and [Cd(linpen)](BF4)2 (3) have been isolated and character­ ized by elemental analysis, spe...
