AMBIENT AIR PROTECTION IN THE SYSTEM OF PUBLIC HEALTH AND BIOLOGICAL SECURITY LEGAL PROVISION.

The article examines the legal and regulatory basis for ambient air protection as an essential element of the environment that affects biological security the health and livelihoods of the population. Proper legal regulation of ambient air protection is important in the implementation of various measures aimed at preserving its quality and, accordingly, preventing possible adverse effects on human health. Ambient air protection is a certain activity directed at reducing the number of pollutants that get into the air by one means or another.

Oxidative C-H/C-H Coupling of Dipyrromethanes with Azines by TiO-Based Photocatalytic System. Synthesis of New BODIPY Dyes and Their Photophysical and Electrochemical Properties.

Oxidative C-H/C-H coupling reactions of dipyrromethanes with azines in the presence of a heterophase oxidative photocatalytic system (O/TiO/visible light irradiation) were carried out. As a result of cyclization of obtained compounds with boron trifluoride etherate, new hetaryl-containing derivatives of 4,4-difluoro-4-boron-3,4-diaza--indacene were synthesized. For the obtained compounds, absorption and luminescence spectra, quantum yields of luminescence as well as cyclic volt-amperograms were measured.

[Features of red blood indexes in elderly patients with ischemic heart disease and pathology of heart valves before and after surgical correction].

Unlabelled: Due to current options of cardiac surgery, operations on the heart of elderly patients have become routine in specialized cardiosurgical centers. The issue of pre- and postoperative anemia of different nature is essential in surgical correction of heart valves and coronary bypass.

Aim: To study indexes of red blood in elderly patients with ischemic heart disease (IHD) and pathology of heart valves before and after surgical correction, including the relationship with position and type of the prosthesis.

Ternary AOT/water/hexane systems as "micellar sieves" for cyanine dye J-aggregates.

We investigate the behavior of J-aggregates of a cyanine dye, 3,3(')-di-(gamma-sulfopropyl)-4,5,4('),5(')-dibenzo-9-ethylthiacarbocyanine betaine pyridinium salt, in AOT/water/hexane reverse micelles (W=2-50), both during the course of rapid microemulsion formation and then after stabilization of the microemulsions at thermodynamic equilibrium. We suggest a new mechanism for J-aggregate formation in reverse micelle solutions. According to this model J-aggregates are formed in the aqueous phase prior to formation of a stable microemulsion, rather than in the process of intermicellar exchange.

[The effect of environmental factors on the concentration of tumor markers in the blood serum and on the indices characterizing thyroid function].

Combined versus separate exposure of male organism to cesium-137 and chemical agents results in a more pronounced hyperferritinemia in the former case. In female chemists the ferritin level is dependent to a considerable extent on the menstrual cycle showing a tendency for the iron-containing protein level to decrease because of the action of a number of chemical agents. The rise of the level of cancer embryonic antigen is more readily seen in persons with high levels of cesium-137.
