the present study was conducted to examine the effect of using latex and nitrile examination gloves on hand dexterity.  a  sample  consisting  of  30  university  students  from  urmia  university  of  medical  sciences participated in this study in 2013. the participants conducted purdue pegboard test in three experimental conditions: bare hand (control), with latex gloves and with nitrile glo...

Rhodococcus rhodochrous NCIMB 11216 produced nitrile hydratase (320 nkat mg of protein(-1)) and amidase activity (38.4 nkat mg of protein(-1)) when grown on a medium containing propionitrile. These enzymes were able to hydrolyze nitrile groups of both granular polyacrylonitriles (PAN) and acrylic fibers. Nitrile groups of PAN40 (molecular mass, 40 kDa) and PAN190 (molecular mass, 190 kDa) were ...

The chemical industry has recently begun to look at enzymes as novel catalysts for many organic syntheses. Nitrile-hydrolyzing enzymes such as nitrile hydratase and nitrilase have great potential as catalysts in processing organic chemical because they can convert nitriles to the corresponding higher-value amides or acids. Recently, the use of bacterial nitrile hydratase for industrial producti...

1- and 1,5-Aminoalkylamine substituted anthraquinones (AAQs, 1C3 1,5C3) were peptide coupled to 1-, 2-, 3-pyrrole lexitropsins generate compounds that incorporated both DNA minor groove intercalating moieties. The corresponding platinum(II) amidine complexes synthesized through a synthetically facile amine-to-platinum mediated nitrile ‘Click’ reaction. precursors as well the biologically evalua...

Based on monitoring the γ process (the lowest temperature-relaxation) in polyacrylonitrile (PAN) by dynamic dielectric spectroscopy, new evidence for the formation of a charge transfer complex between bromine dopants and nitrile groups is presented. The experimental work is carried out on PAN and nitrile polymerized PAN with and without bromine doping and the effects of these factors on the γ p...

The distribution of phenylacetaldoxime-degrading and pyridine-3-aldoxime-degrading ability was examined with intact cells of 975 microorganisms, including 45 genera of bacteria, 11 genera of actinomyces, 22 genera of yeasts, and 37 genera of fungi, by monitoring the decrease of the aldoximes by high-pressure liquid chromatography. The abilities were found to be widely distributed in bacteria, a...

In this study, new Cu(II)/chitosan-based systems were designed via (i) the treatment of chitosan with sodium sulfate (1a) or acetate (1b); (ii) coating 1a 2a a hyaluronate layer (2a and 2b, correspondingly); (iii) cholesterol–chitosan conjugate (3a) (3b); (iv) succination 1b to afford 4a 4b 2b yield 5a 5b. The catalytic properties elaborated in various organic transformations evaluated. use cop...
