In the Arctic region, adaptive reactions of the body put pressure on its functional systems and are accompanied by changes in cerebral energy metabolism in the central nervous system. Despite the fact that patterns of interhemispheric asymmetry and interaction are part of the brain’s essential, fundamental mechanism, no data is currently available on the neurometabolic features of interhemispheric asymmetry in men and women living in the Arctic zone of the Russian Federation. The aim of this paper was to identify the differences in cerebral energy metabolism in men and women born and living in the Arctic zone of the Russian Federation with different types of interhemispheric asymmetry according to the distribution of DC-potential level. Materials and methods. The study involved 63 subjects (30 men and 33 women) aged 30–34 years born and living in Arkhangelsk. Cerebral energy metabolism was assessed using the 5-channel Neuro-KM hardware and software complex. Distribution of DC-potential level was analysed by mapping the monopolar values and calculating their gradients. To calculate interhemispheric asymmetry of cerebral energy metabolism, an interhemispheric gradient was used, i.e. the potential difference between the right and left temporal leads (Td-Ts). The obtained DC-potential level results were compared with average standard values. The results of the study indicate differences in the distribution of the processes of cerebral energy metabolism in men and women with different types of hemispheric dominance. The most balanced cerebral metabolism was identified in men with right hemisphere dominance and in women with left hemisphere dominance. The presence of sex-related differences in the hemispheric asymmetry of cerebral energy metabolism may reflect different strategies of adaptation to the climatic conditions of northern latitudes in men and women.

The aim of the study was to determine the levels of thyroid antibodies and their relationship with thyroid hormones and thyroglobulin in euthyroid men and women, residents of the Arctic zone of the Russian Federation. A total of 208 apparently healthy people were enrolled in this study and classified into two groups depending on gender and level of autoantibodies in the blood. Serum hormones of the pituitary-thyroid system, thyroglobulin and antibodies concentration was measured by enzyme immunoassay. The prevalence of positive antibodies among various examined groups was determined and the characteristics of euthyroid subjects with abnormal thyroid antibodies levels were studied. Circulating positive thyroid antibodies were found in 20% of the surveyed residents of the Arctic zone of the Russian Federation. The median serum antibodies against thyroid peroxidase (AntiTPO) or thyroglobulin (AntiTG) levels and the percentage of people in general population with positive antibodies (i.e. AntiTPO ≥ 50 IU / ml and / or AntiTG ≥ 100 IU / ml) were statistically significant higher in women than in men, p < 0.01. Such thyroid antibodies levels were associated with a higher thyroid gland functional activity in women, which was demonstrated by significantly higher thyroxin level and lower thyroglobulin value in the peripheral blood. Part of women positive for AntiTPO increased with age from 18 to 33% (in groups aged 18-44 and 45-59 years, p = 0.04). The findings of the study reveal correlation between thyroid function test and thyroid antibodies levels, elaborating the clinical importance of thyroid antibodies in clinical examination and follow-up of patients with autoimmune thyroid disorders.

The article is devoted to the study of modern theoretical and legal problems of ensuring biological security in the Arctic zone of the Russian Federation. The published Draft of Federal law No. 850485-7“On biological security of the Russian Federation”provides an opportunity to take a closer look at the problem of legal provision of biological security in relation to the most vulnerable ecosystems, and, first of all, the Arctic. The article considers the most important features and potential risks of the Arctic zone of the Russian Federation of critical importance from the point of view of biological hazards, the features (specificity) of biological safety problems from the point of view of organizational-legal features and, in particular, from the perspective of environmental law. It is proved that, given the special situation of the Arctic zone of the Russian Federation, in addition to the base Federal law“About biological safety” required a specific law on biological and ecological safety of the Arctic zone of the Russian Federation, which should be generated on a slightly different model than the draft Federal law «On biological safety”, to wear the most specific, applied nature.

The paper considers the priorities of the state policy of the Russian Federation in the Arctic, from the point of view of the development of scientific research, identified by the main strategic documents of national policy and security in the Arctic zone of the Russian Federation. Measures for implementation of priorities in the development of scientific research in the Arctic can be divided into three main sections: 1. Scientific projects and expeditions in the Arctic; 2. International activities; 3. Coordination and implementation of integrated research in the Arctic. Note that currently the Ministry of education and science of the Russian Federation develops the Analytical Coordination Program “Comprehensive research of the Arctic and Antarctic”, in cooperation with the federal state bodies and Governance of the Subjects of the Arctic zone of the Russian Federation. The mechanism of the Program will ensure coordination between state bodies for integrated scientific researches in the Arctic in the interests of economic and scientific development of the region, and the creation of the scientific, technical and technological reserve in order to ensure of national security in the Arctic zone of the Russian Federation.
