In cultured skeletal muscle cells of chick, one intermediate filament protein, vimentin, is primarily formed and then synthesis of desmin follows. Coexistence of vimentin and desmin has been immunocytochemically confirmed in chick embryonic skeletal musclecells. Immunofluorescent localization of vimentin and desmin has been described in developing myocardial cells of hamster. However, initial localization of desmin and vimentin in early embryonic heart has not been reported in detail. By quick-freeze deep-etch method a loose network of intermediate filaments was revealed to exist surrounding myofibrils. In this report, immunocytochemical localization of desmin and vimentin is visualized in early stages of chick embryonic my ocardium.Chick embryos, Hamburger-Hamilton (H-H) stage 8 to hatch, and 1 day old postnatal chicks were used in this study. For immunofluorescence study, each embryo was fixed with 4% paraformaldehyde and embedded in Epon 812. De-epoxinized with sodium methoxide, semithin sections were stained with primary antibodies (rabbit anti-desmin antibody and anti-vimentin antibody)and secondary antibody (RITC conjugated goat-anti rabbit IgG).

The reasons for the formation of varnish deposits of turbine oils are determined. It is shown that the performance of turbine oils is determined by methods of ASTM D7843 (MPC) and ASTM D6971 (RUL) can be assessed, the process of formation of varnish deposits, the level of antioxidant properties, antioxidant content of, amend, and extend the oil change, and to predict critical situation in the operation of turbine equipment. The mechanism of formation of varnish deposits in turbine oils is proposed.

One of the complex problems of modern experimental toxicology remains the molecular mechanism of formation of human health disorders separated at different time periods from acute or chronic exposure to toxic environmental pollutants (ecotoxicants). Identifying and understanding what epigenetic changes are induced by the environment, and how they can lead to unfavorable outcome, are vital for protecting public health. Therefore, we consider it important a modern understanding of epigenetic mechanisms involved in the life cycle of mammals and assess available data on the environmentally caused epigenetic toxicity and, accordingly fledging epigenenomic (epigenetic) regulatory toxicology.

As a result of the conducted research the problems of development of human capital and basic pre-conditions of providing of his competitiveness are certain. Analyzed the loud speaker of charges on development of education and health protection of summary budget of Ukraine and measures on the improvement of economic situation in Ukraine and providing of development of human capital are offered. The basic types of investments are certain in a human capital on levels and subjects of investing. The mechanism of forming of human capital is presented. The mechanism of forming of human capital is presented. It is grounded, that for strategic development of human capital of Ukraine and achievement of equilibrium and balanced of economy in the conditions of globalization modernization of public policy is needed in area of education, namely, creation of the system of education, oriented to forming and development of skills and jurisdictions of man, necessary for innovative activity. Keywords human capital, investments in a human capital, competitiveness, economic state of affairs, payment for work.
