Phosphinic compounds have potential as amide-bond mimetics in the development of novel peptidomimetics, enzyme inhibitors, and metal-binding ligands. Novel pseudo-oligopeptides with two phosphinic acid groups embedded in the peptide backbone serving as amide-bond surrogates, Psi[P(O,OH)--CH(2)], were targeted. A series of linear and cyclic pseudo-oligopeptides with two phosphinic acid groups ar...

Pseudo-Pseudo-Myocardial Infarction To the Editor: Hung and colleagues1 present a very important example of a pseudo-infarction pattern presumably related to pancreatitis, one of several clinical situations in which thrombolytic therapy is either not indicated or contraindicated. I am intrigued by the pattern of the bizarre T waves in the limb leads and wonder if part or all of this phenomenon ...

As a part of the development of a new design process of close capture exhausts systems for machining devices, based on fluid flows modeling, an experimental apparatus was realised, which recreates a machining operation in experimentally controlled conditions. The properties of the obtained spray of solid particles were entirely characterised using Phase Doppler Anemometry (PDA), in order to be ...

More and larger blast furnaces have been constructed for ironmaking across the world in recent years due to advantages of high productivity, energy efficiency low cost. Slag plays important role a furnace produce high-quality hot metal maintain smooth operations. Liquidus temperatures are essential information slag avoid formation solid phase during process tapping. The principal components iro...

The aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎It is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

intestinal pseudo-obstruction is a condition in which the intestine’s ability to push food through is reduced. it often leads to the dilation of the various parts of the bowel. it can be idiopathic or inherited from a parent, or caused by another disease. we report a rare case of human immunodeficiency virus (hiv) infection in a 3-year-old boy who referred with acute abdominal pain, and was lat...

background: phic31 integrase is a dna site-specific recombinase integrates dna into the chromosomes between the two sites of attb and attp. several pseudo attps have been identified in mammalian genomes with critical features for long-term expression of transgene. in this manuscript, we report a novel intrinsic pseudo attp site named chol1 in the chinese hamster genome implementing an inverse p...
