SUMMARYWest Nile virus (WNV) strains belonging to lineage 2 were detected and isolated from the tissues of a goshawk and two carrion crows in Sardinia in August 2012. According to NS3 sequence analysis, the Sardinian isolates shared a high level of similarity with those of Italian lineage 2 strains which circulated in 2011 and with the homologous sequence of the 2004 Hungarian isolate. Following the human fatality reported in 2011 in Olbia, this study is the first to report the spread and enzootic circulation of WNV lineage 2 in Sardinia.

The article presents the results of genotyping of 156 Simmental cows for the genes of kappa casein (CSN3), beta-lactoglobulin (BLG), alpha-lactalbumin (LALBA) and leptin (LEP). Studies have shown that the population for all genes is in a state of equilibrium distribution of genotypes, which indicates the absence of factors that change allele frequencies. For the CSN3 gene, the frequency of genotypes A/A, A/B, and B/B is 0.583, 0.385, and 0.032; alleles A and B - 0.776 and 0.224. For the BLG gene, the frequency of the corresponding genotypes is 0.449, 0.455, and 0.096; alleles A and B - 0.676 and 0.324. The occurrence of the LALBA gene genotypes is as follows: A/A – 0.513, A/B – 0.429, B/B – 0.058; allele A – 0.728, allele B – 0.272. Distribution of genotypic classes of the LEP gene: C/C – 0.429, C/T – 0.481, T/T – 0.09; frequency of alleles C and T – 0.67 and 0.33. The observed population structure with a low frequency of B/B genotypes for the CSN3 and BLG genes associated with protein-milkability, but a relatively high level of heterozygosity, demonstrates a stable equilibrium of allele frequencies, which is possible in the case of selection in favor of heterozygotes.

Aim. To assess the associations between depression and coronary artery disease (CAD) in an open female and male population of a middle-urbanized city of Western Siberia.Material and methods. Two cross-sectional epidemiological studies were carried out on an open population of a middle-urbanized Siberian city among men and women aged 25-64 years old. The prevalenceof CAD was assessed based on standard epidemiological methods. To determine the severity of depression, the algorithms of the WHO program MONICA-Psychosocial were used. The severity of depression was assessed as low, moderate, and high. On the basis of the algorithm, the levels of depression were established: low and moderate levels — no sign, high level — presence of a sign.Results. In an open population of 25-64 years old, a moderately urbanized Siberian city, the prevalence of CAD according to extended and lax epidemiological criteria prevailed in men, while strict epidemiological criteria did not reveal significant differences in the male and female subpopulations. In the female subpopulation, a tendency towards an increase in the prevalence of a high level of depression was revealed due to its predominance in young age groups.It has been shown that the depression increases the probability of detecting CAD in accordance with the expanded epidemiological criteria in men and women by 21,07 and 16,04 times, respectively.Conclusion. When using epidemiological criteria for CAD in the presence of depression, the probability of detecting CAD is higher, both in men and women. At the same time, the highest odds ratios are characteristic for a certain type of CAD, the least — CAD by probable signs.

The article is devoted to the four-year (2017–2020) monitoring of gas emissions from the bottom of the Seyakha Crater, located in the central part of the Yamal Peninsula (north of Western Siberia). The crater was formed on 28 June 2017 due to a powerful blowout, self-ignition and explosion of gas (mainly methane) at the site of a heaving mound in the river channel. On the basis of a comprehensive analysis of expeditionary geological and geophysical data (a set of geophysical equipment, including echo sounders and GPR was used) and remote sensing data (from space and with the use of UAVs), the continuing nature of the gas emissions from the bottom of the crater was proven. It was revealed that the area of gas seeps in 2019 and 2020 increased by about 10 times compared to 2017 and 2018. Gas in the cryolithosphere of the Arctic exists in free and hydrated states, has a predominantly methane composition, whereas this methane is of a biochemical, thermogenic and/or mixed type. It was concluded that the cryolithosphere of Yamal has a high level of gas saturation and is an almost inexhaustible unconventional source of energy resources for the serving of local needs.

Purpose: to identify the main environmental problems in areas of intensive use of irrigated lands in Western Siberia and to study the relationship between their manifestations and the territorial specifics of the irrigation land use functioning. Materials and methods. The research was carried out on the basis of a systematic approach and comparative geographical analysis. The indicators characterizing the modern structure and territorial specifics of irrigated land use, and parameters reflecting the ecological state of irrigated lands and adjacent territories are studied. Discussions. It was found that the specifics of the identified environmental problems depends not only on type of irrigated lands use but also on the territorial differentiation of irrigated land use and its specialization. For suburban areas with potato and vegetable growing specialization, environmental problems arising as a result of higher intensification of irrigation land use and the proximity effect of Western Siberia metropolis have been identified, which predetermines a high degree of environmental pollution and a high level of land and water resources degradation. For areas with livestock specialization, located in the peripheral and most arid natural and climatic conditions, a great dependence of environmental problems on the irrational structure of irrigation land use and non-observance of norms and technologies for irrigation has been established. Conclusions. For better understanding of the environmental problems causes, it is necessary to study the relationship between their manifestations and the territorial specifics of the irrigation land use functioning. The results of this study can contribute to the search for ways of reducing the irrigation impact on the environment and the development of effective strategies for the sustainable development of irrigation land use in Western Siberia.

The article is devoted to the study of medical practice in Western Siberia of the late XIX - early XX centuries. Attention is paid to the organization of medical practice in the Tobolsk province. The quantitative and official composition of medical personnel is described. The relevance of the study is due to the fact that on the basis of a wide body of diverse material for the first time the experience of the activities and biographies of medical inspectors: N. A. Stroganov, F. K. Zembitsky, V. I. Nikitenko, M. V. Miloslavsky, G. N. Egorov is considered. Their role in the development of medical practice in the Tobolsk province of 1895-1917 is described. It is shown that these inspectors had a high level of education and extensive experience in medical work. It is pointed out that, despite all the efforts and significant success in the development of medical practice, there were objective difficulties in this field of activity, among which there was a shortage of personnel, funding, long distances between settlements, the Russian-Japanese War and World War I, etc. The authors use a representative base of both published sources and unpublished materials from the collections of the State Archives of Tobolsk.

This study was developed at the Campus (C) and the Zoo-botanical Park (PZ) at the Federal University of Acre, with the purpose of identifying endoparasites in the avifauna of those locations. The birds were captured using 10 mist nets. The nets were set from 1 p.m. to 5 p.m.. The faecal samples collected were stored in Merthiolate, Iodine and Formaldehyde (MIF). Willies and direct methods were used for the diagnostic of endoparasites. Two hundred and eighty-seven birds were captured, with 34 recaptures, which resulted in 253 different specimens – 158 on the campus and 95 at the PZ. The birds caught were from 58 different species, belonging to 25 families and 12 orders. Fecal samples from 193 birds belonging to 49 species from 11 orders and 18 families were obtained and analyzed. The following endoparasites were identified: Eimeria sp., Entamoeba coli, Entamoeba histolytica, Iodamoeba bütschlii, Isospora sp., Enterobius vermicularis, Heterakis gallinarum, Ascaridia galli, Strongyloides avium, Capillaria spp., Ancylostoma spp., Raillietina sp., Choanotaenia sp., Microphallus sp., and Echinostoma revolutum. Eimeria sp. was the most frequent parasite found in most bird species. The results showed a high level of endoparasitic infection in the aviary community in the two study areas.
