EFFECT OF FOOD CHEMICAL COMPOSITION ON POPULATION HEALTH IN OMSK REGION
Abstract
With the application of the method of risk assessment, there have been studied effects of chemicals in food on the population health in the Omsk region in the period 1996-2012. The level of contamination of food with chemical carcinogens increased in the periods 1996-2004 and 2009-2012. The population carcinogenic risk was 5 х 10 -4 and 6.6 х 10 -4 respectively (the levels unacceptable for the population on the whole). The risk of noncancer effects was assessed taking into account influence on the critical organs (systems). The value of the hazard index (HI) > 1 (not acceptable) in the period 1996-2004, was received for the effects on the nervous system (central and peripheral), the cardiovascular system and skin; in the period 2009-2012, the critical organs and systems were the endocrine, cardiovascular, central nervous, urinary systems, the gastrointestinal tract, the blood system, the immune system, skin. Generally in the period 1994-2012, the levels of toxicants' effects in food increased, what caused an increased number of the organs (systems) - targets. Due to the content of chemicals, mainly arsenic, the main food groups with adverse effects on the human body were bakery goods and products of grain processing.

ESTIMATION OF ACTUAL IRON CONSUMPTION BY ADOLESCENT POPULATION IN REGION WITH HIGH CONTENT OF IRON IN DRINKING WATER
Abstract
A hygienic estimation of the actual average daily dose (AADD) of iron, consumed by the adolescent population with the sources of its per oral administration in human bodies in the conditions of iron excess (0.8 mg/l) in tap water has been performed. An object of the study was a random sample of 156 schoolchildren aged 14-17 years from Vladivostok. Methods: all adolescents were interviewed with use of a questionnaire that included questions about daily consumption of tap water, bottled water, 21 food products and dishes. Iron concentration in food and drinking water was determined according to the reference tables and laboratory findings. Results: the harmless levels of AADD of iron for adolescent health (about 17 mg/day) were stated. An occurrence frequency of iron consumption deficiency was equal to 28.08 (boys) and 58,54 (girls) cases per 100 adolescents. Conclusions: against iron excess in tap water according to the organoleptic limiting sign of iron content harmfulness (up to 2.7 MPC), iron consumption deficiency is formed by lower intake of high bioavailable iron sources: eggs, fishes (girls), eggs, sausage products and animal meat (boys).

CHARACTERISTICS OF INITIAL BIOETHICAL VIEWS OF MEDICAL SCHOOL STUDENTS
Abstract
The article has presented research results of bioethical views shared by first- and second-year students of the Faculty of General Medicine of the Northern State Medical University (Arkhangelsk) before studying the academic discipline "Bioethics". The subject of the medical and sociological research included the students' knowledge about the limits of medical interventions in natural processes of birth and death, as well as their attitude to biomedical technologies associated with beginning, continuation and an end of a human life. The results of the study have shown that the students had no formed bioethical concepts of living organisms and opportunities for medical procedures with them. Some of them did not have their own opinions about that (45.4 %; 95 % CI 40.0-51.1). Positive (33.7 %; 95 % CI 28.5-39.2) and negative (20.9 %; 95 % CI 16.6-25.8) perceptions of others varied a lot depending on specificity of biomedical technologies.

EPIDEMIOLOGICAL FEATURES OF HUMAN PAPILLOMA VIRAL INFECTION
Abstract
Cervical cancer is an important public health problem. The incidence of cervical cancer in the world is 10.6 per 100,000 women. Often in the literature, cervical cancer is called a disease of inequality due to a significant difference in the morbidity and mortality rates between the developed and developing countries. In Russia, the mortality and incidence rates of cervical cancer do not tend to a decrease. High prevalence of human papilloma viral infection, lack of organized screening, an organized cytological registry and quality-controlled cytology can be the reasons of the low success rate in implementation of cervical cancer prevention programs. There is a need of studies of human papilloma virus (HPV) prevalence in Russia, a need of national screening programs, development of laws regulating use of HPV vaccine.

SYNERGETIC BIOPSYCHOSOCIOSPIRITUAL CONCEPTION OF OBESITY PANDEMY
Abstract
The obesity pandemy has reached all countries and peoples and become a hedonistic mentality trap of "alimentary happiness" of the consumer society. There has been proposed a synergetic biopsychosociospiritual conception of obesity including three prenosological fractals: predisposition - an adipogenic family, latent - adipogenic diathesis, initial - overweight, and three nosological fractals: a full-scale clinical picture, chronization and an outcome. There have been grounded mechanisms of development and criteria of a social epidemic, a destructive social epidemic and a pandemy of obesity. A multidisciplinary program of preventive-correctional and medical-rehabilitation aid has been worked out and introduced into practice in a number of pilot models.

PSYCHOEMOTIONAL STRESS AND EATING BEHAVIOR IN KAZAKHSTAN
Abstract
The aim of this study was to assess the level of psychoemotional stress and its association with eating behavior in the town of Turkestan, Southern Kazakhstan. Turkestan region is considered as one of the most unfavourable regions in Kazakhstan with poor ecologic conditions. Altogether, 637 individuals from the population served by the policlinic of the International Kazakh-Turkish University participated in a cross-sectional study. The level of stress was assessed using the Perceived Stress Scale-10 questionnaire. Eating behavior was assessed using the Dutch Eating Behaviour Questionnaire. Multinomial logistic regression models and multivariable linear models were applied to study associations between stress and eating behavior. The prevalence of light, moderate and intensive stress was 38.5 %, 50.2 % and 11.3 %, respectively. The prevalence of restrictive, emotional and external types of eating behavior was 30.3 %, 37.5 % and 32.2 %, respectively. We observed positive and statistically significant association between the level of stress and external type of eating behavior. Moreover, eating behavior was also associated with gender, age and education.

ACTOPROTECTIVE ACTIVITY OF COMPLEX BIOLOGICS BASED ON LICHENS THALLI AND RHODIOLA ROSEA
Abstract
There has been developed a mechanochemical technology of one-stage production of highly effective solid phase biocomplexes (without use of solvents) based on "the universal active filler" - lichenβ-oligosaccharides polymer matrix. It has been shown that lichens can be a source for production of the filler with apparent adsorption activity for solid dosage forms (SDF). It has been a statistically significant establishment that the bicomponent vegetative mechanocomplex based on the lichen β-oligosaccharides filler and a small amount of Rhodiola rosea has a broad spectrum of adaptogenic effects, it increases body's resistance of laboratory animals to physical loads and extreme factors of different nature.

COMPARATIVE CHARACTERISTICS OF BIOLOGICAL PROPERTIES OF S. AUREUS ISOLATED FROM HUMANS AND BIRDS
Abstract
The purpose of this study was to investigate biological properties of S. aureus isolated from a poultry plant staff, birds and bacteria carriers. Almost all the isolates of S. aureus had a number of virulence factors. All strains of S. aureus were characterized by an ability to form biofilms. In spite of the fact that individual values of biofilm biomass of different strains varied widely, there were no significant statistical differences between the mean values of these strains isolated from various sources. The study of antibiotic susceptibility revealed that the cultures isolated from bacteria carriers were sensitive to a wide spectrum of antibacterial agents. At the same time, strains isolated from the birds and a number of strains isolated from the staff were resistant to antibacterial agents used in poultry keeping. Almost all the isolates of bacteria carriers were lysed by typical bacteriophages of the "H" set ("Human"). Most of the isolates from the birds and the third part of the staff-strains were not sensitive to bacteriophages. The cultures isolated from the bacteria carriers belonged to the Ekovar A ("Human"). Some strains isolated from the birds and the poultry farm staff also belonged to this Ekovar, while most of the "bird" S. aureus cultures belonged to the Ekovar B ("Chicken"). Thus at the poultry farm, there was observed an exchange of S. aureus strains among the staff and the birds.

NEURAL EMULATORS IN IDENTIFICATION OF ORDER PARAMETERS IN HUMAN ECOLOGY
Abstract
Binary classification offers the procedure of identification of more significant x i diagnostic features (order parameters) for the systems being in different conditions and divided by a neural emulator. Ranking of x i is realized by many repetitions (p > 100) of problem solving of binary classification by a neural emulator at initial set of feature weights w j io where j is an iteration number (i = 1, 2 ... p) from the interval (0, 1) with an uniform distribution. Accuracy of identification increases by increased p (p > 1 000, p > 10 4), that is demonstrated on parameters of cardiovascular system of groups of people working at night shifts.
