The proliferation, differentiation and death of cardiomyocytes during exposure to an antioxidant

Influence of ionolum--vitamin E analog on differentiation, proliferative activity, cell death and content of products of lipid peroxide oxidation in chick embryo cardiac muscular tissue was studied in normal embryogenesis and in myocardial hypertrophy development. Administration of antioxidant to chick embryo was shown to result in intensified and prolonged proliferation, delayed differentiation and reduced cardiomyocyte death index both in normal histogenesis and in myocardial hypertrophy development. Use of the drug leads to viability increase in embryos exposed to extreme environmental factor action.     

Additive package for alternative automotive fuels

The results of studies aimed at improving many performance properties, including the environmental properties, of automotive gasolines by addition of oxygen-containing components, primarily aliphatic alcohols — methanol and ethanol, and reducing the corrosiveness of alcohol-containing fuels are reported. The corrosion inhibitors, antiwear additives, and a metal deactivator that make up the additive package and can increase the efficiency of gasoline-alcohol fuel composites were developed using available feedstock.     

High-efficiency operation of chemical oxygen-iodine laser usingnitrogen as buffer gas

High-efficiency operation of supersonic chemical oxygen-iodine laser (COIL) with an advanced jet-type singlet oxygen generator using nitrogen as buffer gas was demonstrated. Laser output was remarkably increased when buffer gas was cooled with liquid nitrogen. The effects of buffer gas temperature on the characteristics of the oxygen-iodine laser medium was discussed. A net chemical efficiency of 23.4% was obtained at 405 W when the chlorine molar flow rate was 19 mmol/s
