Biomimetic Water Oxidation Catalyzed by a Binuclear Ruthenium (IV) Nitrido-Chloride Complex with Lithium Counter-Cations.

The lithium salt of the binuclear nitrido complex of ruthenium (IV) Li(RuNCl·2HO) was synthesized. Using UV spectroscopy and voltammetry, we studied complex behavior in aqueous solutions. It was found that in dilute solutions of this compound, Cl ions are replaced by HO molecules, and the intra-sphere redox reaction between Ru (IV) and HO, as well as the oxidation of water with the formation of oxygen and the acidic dissociation of coordinated water molecules also have been taking place.

[The content of apolipoproteins in blood M and parameters of lipid metabolism in population of North Polar regions and Southern regions of Caucasus].

The study was carried out concerning the between content of apolipoproteins A and B in blood and lipid metabolism in population of North Polar regions and Southern regions of Caucasus. The differences of correlation relationships depending on concentration of apolipoproteins A and B in blood in population dwelling in territories climate geographic regions were detected.
