Concentrations of cadmium, cobalt, cupper, iron, manganese and nickel were determined in four organs (liver, gills, ovaries muscles) Acanthopagrus latus, which collected from Iraqi marine waters during the period between November 2010 October 2011. Heavy metals have been by means Atomic Absorption Spectrophotometry. The fish average weight was 61.2 g length 144 mm. Nickel showed highest values ...

Epilepsy is one of the most common neurological disorders. as second burdensome neurologic disorder worldwide in terms disability-adjusted life years. Copper (Cu) involved a number enzymes with catalase and oxidase-type reactions. This study aimed to identify role serum copper etiology epilepsy its response treatment Methods: prospective case controlled that was conducted on patients attending ...

Based on the supramolecular interaction between vancomycin (Van), an antibiotic glycopeptide, and D-Ala-D-Ala (DADA) dipeptides, a novel class of artificial metalloenzymes was synthesized characterized. The presence iridium(III) ligand at N-terminus DADA allowed use metalloenzyme as catalyst in asymmetric transfer hydrogenation cyclic imines. In particular, type link metal-chelating moiety foun...

In spite of development of nanotechnology and creation of new opportunities for industry, new applications and products initiated by this technology may cause harmful effects on human health and environment. Unfortunately, there is no sufficient information on the harmful effects caused by application of some nano materials; the current knowledge in this field is limited solely to the nano part...

Single-atom catalysts hold the potential to significantly impact chemical sector, pushing boundaries of catalysis in new, uncharted directions. These materials, featuring isolated metal species ligated on solid supports, can exist many coordination environments, all which have shown important functions specific transformations. Their emergence has also provided exciting opportunities for mimick...

Catalytic dehydrogenation of alcohols represents an attractive approach for future applications as hydrogen storage systems and clean synthesis fine chemicals. Herein, overview recent progress in homogeneously catalyzed acceptorless alcohol is presented. In Nature, efficiently by multiple metalloenzymes where a non-noble metal–ligand interplay key to activate transform substrate. We highlight t...
