“…The results of our study have shown that the fish of the Arctic rivers of Yakutia are rich in proteins and fats, which is also noted in other studies (Abramov et al 2015;Abramov et al 2018). The meat of the commercial Arctic cisco caught in the lower reaches of the Yenisei river basin in Siberia is also characterized by a high fat content −17.9 ± 0.35 g/100 g (Gnedov 2010).…”

AbstractThe peculiarity of natural conditions of Yakutia plays an important role in the formation of economic activities of its population. A significant number of rivers and lakes are a favorable condition for the development and preservation of traditional fishing. Currently, more than 89% of the commercial fish catch is produced in the lower reaches of the large northern rivers and lakes in the Arctic and subarctic zones of Yakutia. The main part of this catch is whitefish species, which are valued for their fat content, protein content, culinary, and taste qualities. Fish is a valuable food product for the population of Yakutia. This article presents the results of the study on the nutritional value and the content of heavy metals in the Arctic cisco meat. The high content of fat and protein in the studied samples shows that the Arctic cisco meat belongs to high-protein and high-calorie products and has a high biological value. It was found that on average, the level of toxic metals in the Arctic cisco meat does not exceed the norms accepted in Russia for fish products. The data obtained suggest that the content of heavy metals in fish is due to the peculiarities of living conditions and environmental pollution. Over the past decades, the volume of fish production in Yakutia has been declining due to the socioeconomic and climatic factors. Due to the anthropogenic pollution of water in rivers and lakes by oil products and effluents and waste from various sectors of the economy, especially the mining industry, there is a reduction in the fish resources and there is a need to monitor the environmental condition of the fishing reservoirs and the fish food quality.

“…sardinella was equal to that in the fish from the Indigirka River (Abramov et al, 2015). Contents of essential metals (Fe, Mn, Cu, Zn, Se) in smoked C. sardinella and C. tugun and content of Zn in smoked C. muksun, C. nasus and C. peled were higher than average values for many raw fish specimen (Tacon & Metian, 2013).…”

“…Cu and Zn in the smoked fish did not exceed permissible limits according to FAO (30 mg kg -1 ) (Varol & Sünbül, 2019). Pb content in smoked C. sardinella slightly exceeded average that in Coregonus sardinella valenciennes fresh fillet from the Indigirka River (Republic Sakha, Russia) (Abramov et al, 2015, recalculated for given moisture 74.6%).

In cold smoked species of genus Coregonus, identified by molecular genetic analysis, contents of fatty acids and heavy metals and arsenic were measured. The highest content of sum of longchain polyunsaturated fatty acids of omega-3 family (LC-PUFA), namely eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids, 6.53±0.78 mg g -1 wet weight, was characteristic of tugun Coregonus tugun. This is the first quantitative estimation (mg LC-PUFA per g of product) of the nutritive value of smoked fish. Thus, to obtain a daily personal doze of 2 EPA+DHA of 1 g, recommended for prevention of cardiovascular diseases, one needs to consume 153 g of the smoked tugun. Metals contents did not exceed standards for fish meat except Pb in least cisco Coregonus sardinella. Accordingly, values of hazard quotients, which estimate benefit-risk ratio of fish intake, indicate that most of the smoked fish species are safe product for human nutrition, except least cisco regarding Pb content.

Aim. To study the contribution of the Ala54Thr genetic polymorphism of the FABP2 gene to the risk of developing type 2 diabetes mellitus among the Yakut population. Materials and methods. The study included participants who filled out a questionnaire approved by the Local Committee on Biomedical Ethics at the Yakut Science Centre of complex medical problems and voluntarily signed an informed consent to conduct a genetic study. The sample consisted of 181 patients of the endocrinological department of the Republican Hospital No. 2 of the State Budgetary Institution “Center for Emergency Medical Care“ with a diagnosis of type 2 diabetes. The comparison group was a sample of 336 volunteers without chronic diseases of the Yakut ethnicity. For molecular genetic analysis, genomic DNA samples were isolated from whole blood. Single nucleotide polymorphism was determined by polymerase chain reaction followed by analysis of restriction fragment length polymorphism. Results. Study showed that polymorphism in the FABP2 gene has an impact on anthropometric parameters and blood biochemical parameters. The risk of developing type 2 diabetes was 1.7 times higher in carriers of the Ala/Thr genotype (odds ratio 1.755, 95% confidence interval – 1.212–2.542; p0.005) compared with carriers of other genotypes. When comparing the average biochemical values, the levels of aspartate transaminase, alanine aminotransferase, glucose and total bilirubin in homozygous carriers of the Ala/Ala genotype were significantly lower than in carriers of other genotypes (р0.05). Carriers of the heterozygous Ala/Thr genotype (р0.05) had the highest level in terms of aspartate aminotransferase and alanine aminotransferase. The highest indicator of the average level of HbA1c and an indicator of total bilirubin were carriers of the Thr/Thr genotype (р0.05). Conclusion. The high prevalence of the negative Thr allele among the Yakut population is probably associated with living conditions in the North, as well as in the traditional type of diet.
