The objective was to study behavioral risk factors of non-infectious diseases, such as physical activity (PA), smoking, food, use of alcoholic beverages in case of a sampled unity of permanent Surgut-dwellers. 2 256 people have been interrogated in an ecological-sociological research by means of telephone interviews. 2 000 people’s samples were processed - 1 000 men and 1 000 women of five age categories: 18 29 years, 30-39 years, 40-49 years, 50-59 and older than 60. Dependence (F = 50.274; p < 0.001) between the indicators of health and PA of the respondents, between PA and presence of children in a family (F = 45.549; p < 0.001) has been revealed. The PA level depends on education (F = 17.130; p < 0.001) and profession (F = 60.273; p = 0.012). Dependences between PA and a marital status (F = 1.128; p = 0.288) have not been revealed. Gender distinctions have not been revealed in PA (F = 2.903; p = 0.313), between PA and heart insufficiency (F = 1.376; p = 0.241), ischemic illness (F = 0.554; p = 0.457), smoking (F = 2.239; p = 0.265), myocardial infarction (F = 4.249; p = 0.047).

This review discusses the analytical synthesis of molecular biological, biochemical, cytological and toxicological properties of the manganese oxide nanoparticles for inhalation into organism in the experiment. Systematization of scientific data provides a more complete view of negative effects arising from the inhalation of manganese oxide nanoparticles.

In the article, there have been presented the results of audiostimulation effect as an environmental factor on psychophysiological parameters of personal decision making (time, errors) in young healthy subjects, as well as on autonomic parameters (heart rate) during visual identification of fragmented objects. Instrumental musical accompaniment with the rhythm of 60-70 beats per minute was more effective in solution of visual tasks under uncertainty. We suppose that it was associated with processes of increased synchronization of rhythmic activity in different areas of the brain and increased stress resistance. The reaction time of personal decision making and the number of correct answers were the main criteria of effectiveness of identification of fragmented visual stimuli in humans.

To identify characteristics of development of human pancreatic stroma in the fetal and neonatal periods of ontogenesis, we have conducted a cross prospective study of 208 pancreases of fetuses (16-40 weeks) and dead newborns. They have been divided into groups by age. Data were processed by methods of nonparametric statistics. It has been established that in pathological pregnancies, formation of the pancreas stroma components was interrupted. A reliable connection between collagen content and perinatal pathology development risk (r s = 0.145, p = 0.001) has been detected, as well as in the groups “collagen - age” and “collagen - cause of death” (r s = -0.184, p = 0.003; r s = -0.194, p = 0.005). In the group of cases caused by separate states, the content of collagen was significantly higher (p = 0.024). Conclusions: it is necessary to consider the risk of development of the perinatal pathology as one of the major factors causing overdevelopment of the pancreas stroma collagen, what reflects environmental impacts on the feto-placentary system.
