[Catering for client groups during the XXII Olympic winter games and XI Paralympic winter games of 2014 in Sochi].

The problems of catering control various client groups during the XXII Olympic Winter Games and XI Paralympic Winter Games of 2014 in Sochi is one of the priorities of the sanitary and epidemiological welfare of the population during mass events. The data on the order of nutrition of guests and participants of the games, control of food items, sanitary and microbiological monitoring of drinking water, food raw materials and products are presented. It is noted that the ongoing supervisory activities contributed to the sanitary and epidemiological well-being during the Games. The purpose of this study was to lighting modern achievements in the field of nutrition and food microbiology in the period of the Olympic Games and the determination of their value to the further improvement and use at when conducting mass gatherings.

[ORGANIZATION OF THE QUALITY CONTROL OF PLACEMENT AND ACCOMMODATION OF PARTICIPANTS ATTENDANTS AND GUESTS OF THE XXII OLYMPIC WINTER GAMES AND XI PARALYMPIC WINTER GAMES OF 2014 IN THE RESORT CITY OF SOCHI].

There is presented the analysis of activities of the Federal Service for Supervision of Consumer Rights protection and Human Welfare to ensure adequate conditions of accommodation of the participants, attendants and guests of the XXII Olympic Winter Games and XI Paralympic Winter Games of 2014 in the Resort city of Sochi according to regulated requirements. There were detected ways of the strengthening the supervision for the quality of the accommodation during mass sports activities for the assurance of the rights for consumers.

[Principle directions for the creation and organization of the system of sanitary-epidemiological safety during the preparations for the XXII Olympic Winter Games and XI Paralympic Winter Games 2014 in Sochi].

The paper generalizes the experience of formation of protection system against biological threats and ensuring sanitary and epidemiological welfare during preparation for the XXII Olympic Winter Games and XI Paralympic Winter Games of 2014 in Sochi. The basic steps for creating this system, since 2007, participation and role of Rospotrebnadzor in this process are shown. The paper deals with such questions as the governmental and administrative structures with federal agencies interaction, development of a regulatory framework governing the safety system of the Olympic Games, development of algorithms of information exchange and management decisions, biological safety in developing infrastructure in Sochi.

[Operation and interaction peculiarities of diagnostic laboratories involved in providing protection from infectious diseases during the XXII Olympic Winter Games and XI Paralympic Winter Games 2014 in Sochi].

The experience of the organization and functioning of the laboratory network during the XXII Olympic Winter Games and XI Paralympic Winter Games of 2014 in Sochi is considered. Efforts to establish an effective system of laboratory support, the order of work and interaction of diagnostic laboratories involved in diseases control of population during the Olympic Games are analyzed.

[Dopplerographic predictors of cognitive status dynamics of patients after carotid angioplasty with stenting].

The authors present dopplerographic predictors of cognitive status dynamics of patients undergoing carotid angioplasty with stenting. It was stated that the cognitive status dynamics depended on the initial condition of patients and reactivity coefficient on hypercapnia in target vascular pool.

[Proliferative activity parameters and their correlation with genetic damage of blood lymphocytes during cultivation under the conditions of cytokinetic block].

The subjects of the study were 15 volunteers aged 22 to 25 years, who underwent 25 air ionization sessions. The effects of genome instability were evaluated, and correlations between indicators of genome damage (lesions of micronuclei and nucleoplasmatic bridges) and parameters of proliferative and replicative activity (mitotic index, proliferative pool, the fraction of rapidly dividing cells, and replication index) of blood lymphocytes in the culture were studied. In order to establish the associations between the parameters, the parallel cultures were exposed to 0.07 mM of the standard mutagen MNNG during 5 hours. The study showed that the course of air ionization did not induce the micronuclei and nucleoplasmatic bridges in binuclear cells, but increased proliferative cell activity. This effect was accompanied by an increase in the fraction of rapidly dividing cells among all the dividing cells, and an increase in the dispersion of all proliferation parameters. MNNG induced a constant level of micronuclei in binuclear cells during the whole course, but not before the beginning of air ionization. The changes in the parameter "the fraction of dividing cells" (proliferative pool) were the most prominent manifestation of the suppression of proliferation by MNNG. MNNG loading inhibited the formation of binuclear cells most of all. The results demonstrate a non-random character of the correlation between the level of micronuclei in binuclear cells and proliferative activity parameters during cell cultivation under the conditions of cytokinetic block.

[Hygienic evaluation of genotoxic effects during artificial air ionization].

The study examined the potential genotoxic activity and the impact of artificial air ionization on lifespan. Experiments on Drosophila melanogaster demonstrated that exposure of the lung to negative (5 x 10(4), 5 x 10(5), and 10(6) ion/cm3) and slight positive (5 x 10(4), 5 x 10(5), and 10(6) ion/cm3) airoions generated on the electrodes at direct-current voltage failed to increase the frequency of dominant lethal mutations in the gametes and to affect the life-span of male flies. Exposure of the flies to deionized air increased the rate of early embryonic lethal mutations.
