Evaluation of the Antioxidant Effect of Dihydroquercetin in Adult Residents of the North under Adverse Environmental Conditions

Introduction: Transport-related air pollution (vehicle exhaust emissions) and the consumption of poor-quality drinking water can play a key role in the activation of oxidative stress in the population of the northern region. Purpose: To study the effectiveness of taking dihydroquercetin to improve the adaptive reserves of antioxidant protection in the adult population of the Khanty-Mansi Autonomous Okrug. Materials and methods: Using test kits, we measured the content of lipid peroxidation products (lipid hydroperoxide and thiobarbituric acid reactive substances) and antioxidant defense of the body (total antioxidant activity and thiol status) in blood serum of 156 young adults residing in the Khanty-Mansi Autonomous Okrug before and after metabolic correction using Baikal dihydroquercetin, an antioxidant herbal preparation, at a dose of 60 mg/day for 30 days. The oxidative stress index was calculated by the formula: lipid hydroperoxides × 2-thiobarbituric acid reactive substances / total antioxidant activity × thiol status. Results: We established increased lipid peroxidation, i.e. higher levels of lipid hydroperoxides and 2-thiobarbituric acid reactive substances, in heavy-duty vehicle drivers occupationally exposed to car exhaust pollutants and urban residents consuming poor-quality tap water with a high content of iron and manganese ions, the excess of which in the form of inorganic compounds can demonstrate prooxidant properties before correction with dihydroquercetin. We also noted a decrease in the parameters of the antioxidant defense of the body (total antioxidant activity and thiol status) below the reference values. The oxidative stress index was 5.4 and 4.9 times higher than the upper limit of adequate values in the group of drivers and residents of the cities of Nyagan and Nefteyugansk, respectively. After taking dihydroquercetin at a dose of 60 mg/day for 30 days, all indicators of oxidative metabolism in both study groups returned to normal. A significant decrease in the level of thiabarbituric acid reactive substances was found in both groups, respectively: p¹ = 0.011 and p² = 0.002, in combination with a statistically significant increase in the total antioxidant activity (p¹ = 0.015 and p² = 0.019) against the background of the most pronounced decrease in the oxidative stress index: p¹ = 0.019 and p² = 0.001, however, not reaching the level of physiologically adequate values. Conclusion: Positive changes in redox metabolism observed following a 30-day correction with the antioxidant drug dihydroquercetin give evidence of the restoration of adaptive resources of the human organism and an increase in its resistance to adverse environmental factors.

Diagnostics of School Involvement of Learners Included in the Practice of Participatory Budgeting

Introduction. The research problem is to determine the measurable results of using a separate educational practice (school initiative budgeting). The purpose of the article is to reveal the relationship between the level of school involvement of students and the intensity of their participation in the practice of school initiative budgeting. Materials and Methods. In 2021–2022 An empirical study was conducted in seven educational institutions of the Khanty-Mansi Autonomous Okrug – Yugra, in which 182 schoolchildren took part. The study included measurements of school involvement in 11 parameters (activities, communication and relationships) of learners who, to varying degrees of activity, participate in school initiative budgeting. Engagement study methodology was used ‒ a modified Gallup Q12 questionnaire, an interview, a questionnaire for schoolchildren and a questionnaire for teachers. Results. An authorʼs model of school involvement, a program for diagnosing school involvement and active participation in school initiative budgeting have been developed. Statistical processing of the measurements made it possible to assert that the intensity of participation in school initiative budgeting correlates with the level of school involvement of students, the more actively a student participates in school initiative budgeting, the higher the degree of his school involvement. Discussion and Conclusion. The presented results testify to the prospects of using the model and scheme for diagnosing school involvement. The materials of the article are of interest in the context of determining the results of the implementation of school initiative budgeting in the practice of Russian educational organizations and school participatory budgeting abroad.

Problems of oil and gas potential realization in Bazhenov-Abalak play in Khanty-Mansi Autonomous Okrug – Yugra

This research aims to analyze problems related to resources, reserves and development of Bazhenov-Abalak oil and gas play and to find geological and technological solutions for bringing reserves into development commercially. This should stabilize oil production in Okrug on the level 210–215 million of tons. Geological, field and statistical data from V.I. Shpilman Research and Analytical Centre for the Rational Use of the Subsoil and Department of Subsurface Management & Natural Resources of Khanty-Mansi Autonomous Okrug – Yugra were retrospectively analyzed during this research. Oil production from Bazhenov-Abalak play using conventional technologies is still sub economic. Running experimental areas and test ranges for industrial approval of development efficiency enhancement technologies for Bazhenov-Abalak play are created on producing fields. Unfortunately, accumulated experience ends up inside oil companies. Undoubtedly, single initiatives of oilmen will not solve a problem of development of huge resources in Bazhenov formation.

Review of a series of clinical observations of the use of "Cell culture for substitution therapy"

Introduction. The necessity to develop new substitutional medical technologies is associated with a high demand for rehabilitative measures of traumatological, surgical, and dental patients and persons with burn disease. The existing clinical practice of using allogeneic and autogenous cells, previously used for these purposes, has not yet been standardized. The aim of the study was to summarize scientific literature data on the clinical effectiveness of cell-based medical biotechnologies for regenerative medicine. Materials and methods. The authors reviewed 29 published scientific sources on the results of clinical trials of the preparation "Cell culture for substitution therapy" in 12 medical institutions of the Ural and Siberian regions of the Russian Federation during the period from 1998 to 2012. Results and discussion. Developed and effectively tested on the basis of medical institutions of Sverdlovsk, Chelyabinsk, Tyumen, Kemerovo regions, the Republic of Sakha (Yakutia) and Khanty-Mansi Autonomous Okrug immunobiological preparation "Cell culture for replacement therapy" had high clinical effectiveness in pathological conditions associated with tissue damage in patients with burns, surgery, trauma and dental profile. The studies demonstrated the key activity of allogeneic fibroblasts in the lesion nidus while reducing the time of extracellular matrix formation during active tissue regeneration. The use of the drug prevented the development of generalized infectious-inflammatory complications, reduced the risk of secondary infections, reduced the period of hospitalization and rehabilitation of patients. Conclusion. Analysis of the literature data on the high efficiency of immunobiological agents for substitution therapy on the example of using the preparation on the basis of allogeneic human fibroblasts, based on modern medical standardization and ethical norms, sets the actual task of their replacement by xenogenic and autologous preparations, which will increase the efficiency and safety of the presented method of treatment, improve the quality, life expectancy and demographic indicators in Russia.

Metabolic syndrome in patients with arterial hypertension living in the Far North (on the example of the Khanty-Mansi Autonomous Okrug — Yugra)

BACKGROUND: Metabolic syndrome currently continues to occupy a leading position in medicine and remains one of the main reasons for discussions among scientists around the world. WHO experts defined the problem of metabolic syndrome as an «epidemic of the 21st century», since its prevalence is currently, according to some estimates, from 10% to 40% among the adult population of the planet.AIM: To study the metabolic syndrome in patients with arterial hypertension living in the Far North; to determine the main variants of the metabolic syndrome that are characteristic of people with arterial hypertension in harsh climatic and geographical conditions and to analyze the frequency of occurrence of the identified variants of the metabolic syndrome depending on the degree of arterial hypertension and gender differences.MATERIALS AND METHODS. This study is presented in the form of 4 main stages: determination of metabolic syndrome variants characteristic of patients with AH living in the North, analysis of the frequency of occurrence of the identified main variants of the metabolic syndrome depending on gender, degree of AH and time spent in the Far North. Study period: March 2018–February 2019.The main inclusion criteria for this study were: the presence of metabolic syndrome, a confirmed diagnosis of arterial hypertension (AH) of 1–3 degrees based on generally accepted criteria (ESH / ESC, 2018), residence in the Far North for at least 1 year. For the diagnosis of MS, the IDF criteria, 2005, were adopted. By design, the work is in the nature of an observational one-sample study, which was conducted in the Khanty-Mansiysk Autonomous Okrug — Yugra, Nizhnevartovsk (KhMAO-Yugra).RESULTS. The study involved 235 people, of which: men — 109 people (46.4±4,77%), women — 126 people (53.6±4,44%). The age of the study participants was 38±7.1 years. According to the degree of AH (according to the criteria, ESH / ESC from 2018), patients are presented as follows: 1st degree AH — 59 people (25.1± 2,83%); 2nd degree AH — 73 people (35.1± 3,11%); 3rd degree AH — 103 people (39.8± 3,19%). By the time of residence in harsh climatic conditions, all patients who took participation in this study were divided into three groups: group 1 — the residence time was from 1 year to 5 years. This group included 56 people (23.8±5,7%). 2 group — the period of stay in the Far North was from 6 to 11 years and this group is represented by 81 patients (34.5±5,3%) , group 3 — patients living in CS conditions for more than 11 years — 98 people (41.7±4,9%). № 1 — WC ≥ 94 cm in men and ≥ 80 cm in women + BP level ≥ 130/85 mm Hg + decrease in HDL cholesterol ≤ 1.03 mmol / L. This combination of the main structural units of MS was observed in 43 +/-3.23% of cases (p<0.0016). Option number 2 — waist ≥ 94 cm in men and ≥ 80 cm in women + BP level ≥ 130/85 mm. rt. Art. + decrease in HDL-C ≤ 1.03 mmol/l + increase in triglycerides ≥ 1.7 mmol/l + increase in fasting glucose ≥ 5.6 mmol/l* — this combination of MS components occurred in 57+/-3.23 % of cases in all patients participating in the study (p<0.0011).CONCLUSION. With an increase in the time spent in the Far North in patients with hypertension, who initially have a 3-component variant of the metabolic syndrome, there is a tendency towards an increase in the main components of the metabolic syndrome.

Обеспеченность витамином D беременных женщин, проживающих в условиях Ханты-Мансийского автономного округа – Югры

The purpose of this study was to assess vitamin D levels in pregnant women living in the Khanty-Mansi Autonomous Okrug – Yugra (Russia). Materials and methods. In the course of a cohort study during the period of 2019–2020, the level of 25(OH)D in the serum of 110 female residents of Khanty-Mansiysk was determined. The subjects were divided into two groups: nonpregnant (control) (n = 58) and pregnant (n = 52) women. Results. Both non-pregnant and pregnant (1st – 2nd trimesters) women living in the Khanty-Mansi Autonomous Okrug – Yugra showed low vitamin D levels: non-pregnant women, 21.3 ± 0.7 ng/ml; pregnant women in the 1st trimester, 20.6 ± 0.6 ng/ml; in the 2nd trimester, 19.2 ± 0.5 ng/ml; in the 3rd trimester, 18.4 ± 0.4 ng/ml. These levels are below the lower limit of physiologically optimal values. Pregnant women in the 2nd and 3rd trimesters had significantly lower concentrations of 25(OH)D compared to non-pregnant women. The hypovitaminosis we identified has a tendency to increase from the 1st to the 3rd trimester, as the mother’s vitamin D requirement steadily increases due to the intensive growth of the foetus’ bones. The average blood vitamin D level of pregnant women in the 3rd trimester was found to be 1.6 times lower than the lower limit of the reference range and 1.2 times lower than that in the control group. The results of the study indicate a need for systemic diagnostic, preventive and corrective measures that will eliminate vitamin D deficiency in women living in the Khanty-Mansi Autonomous Okrug – Yugra.

Species spectrum of nonpolio enteroviruses in KhMAO–Yugra during the prepandemic and pandemic periods

BACKGROUND: The characteristics of the regional features of the etiological structure of nonpolio enterovirus infection before and during the coronavirus disease 2019 (COVID-19) pandemic were evaluated.
 AIM: To assess the monitoring of the etiologies of enterovirus infection in the prepandemic and pandemic periods.
 MATERIALS AND METHODS: Data from the forms of statistical observation for 20132022 and the results of molecular genetic studies of nonpolio EVI were used.
 RESULTS: The dynamics of the incidence of enterovirus infection in the KhantyMansi Autonomous Okrug before the COVID-19 pandemic was characterized by high activity levels of the epidemic process, exceeding the average for the Russian Federation by 56 times. The urban population, with a predominance of children aged 6 years, mainly contributed to the total incidence of enterovirus infection. During the period with the highest incidence rates in 2017 and 2019, Coxsackie A6 viruses in combination with ECHO30, Coxsackie A9 dominated, and during the period of their decline, the proportion of enterovirus A71, Coxsackie A16 increased. During the pandemic, the calculated trends of dynamics for 2022 were confirmed for dominant viruses and enterovirus A71. In the same year, Coxsackie B2 and ECHO6 viruses were increasingly identified, which were previously circulated irregularly and in isolated cases. The prevalence of CV-A6 in the epidemic process was accompanied by clinical manifestations of infection, mainly as enterovirus vesicular stomatitis, with a high frequency of ECHO30, computer cases were recorded in most cases.
 CONCLUSION: Based on the results of monitoring the etiological structure of nonpoliomyelitis enterovirus infection in the prepandemic period, a further increase in morbidity in enterovirus infection is predicted in the KhantyMansi Autonomous Okrug. Genotyping of the detected strains makes it possible to determine the spectrum of enterovirus strains endemic to the territory and predict their prevalence, which is necessary to prevent the spread of enterovirus infection and ensure sanitary and epidemiological well-being in the region.

Extraction of petroleum products from wastewater by natural sorbents of the Arctic

Oil and gas production in the Yamal-Nenets and Khanty-Mansi Autonomous Okrugs has an adverse impact on the ecological state of the Arctic. In order to prevent pollution of northern water bodies with oil products, local natural materials (peat, moss and reindeer moss) are considered as sorbents. Sorption isotherms were constructed for different initial concentrations of the pollutant (250.50 and 0.5 mg/dm3); regularities of changes in the intensity of sorption of oil products are determined. The sorbents were modified by microwave radiation, which had a noticeable positive effect on reindeer moss samples. Based on the data of a laboratory experiment, the design parameters of filter cassettes were calculated. Efficiency and low cost suggest the economic feasibility of using these materials in wastewater treatment technologies.

ДВИГАТЕЛЬНАЯ АКТИВНОСТЬ ПЛОДА И МОРФОЛОГИЧЕСКИЕ ОСОБЕННОСТИ ТКАНИ ПЛАЦЕНТЫ У ПАЦИЕНТОК С РАННЕЙ И ПОЗДНЕЙ ПРЕЭКЛАМПСИЕЙ

The study aims to analyze the features of fetal motor activity and afterbirths’ common pathomorphological differences in women with early and late preeclampsia living in areas equated to the conditions of the Far North (Khanty-Mansi Autonomous Okrug – Ugra). The study examined 385 labor cases of patients who were classified as follows: 131 patients with early onset of preeclampsia (up to 34 weeks), 144 patients with late onset of preeclampsia (after 34 weeks), and 110 apparently healthy patients with the physiological course of pregnancy. The analysis of fetal motor activity and morphological studies of the afterbirths was carried out. When applying subjective and objective fetal movements counting methods, patients with early preeclampsia had statistically significantly lower fetal motor activity and more cases of chorionic villous maturation disorder, chorangiosis, myocardial infarctions, and placental pseudoinfarctions. Ascending infection of the placenta prevails in both early and late-onset preeclampsia.

It is determined that there is a 55, 25, 10, and 7.5 % negative trend in an indicator of norm at the ages of 40, 50, 60, and 70, respectively, with the probability of osteopenia development and a statistically significant risk of osteoporosis development, especially after the age of 70. Osteoporosis is diagnosed in every third 51–60 y. o. female, almost in every second by the age of 61–70 (45 %), and in 82.5 % of patients after the age of 71.

Конкурс муниципальных стратегий – 2022: история стратегирования и флагманские проекты

The article describes the experience of designing and conducting a competition of municipal strategies “Implemented Strategies: From Idea to Execution”, held in 2022. The competition is seen as a method of practice analysis of municipal strategic planning in Russia during 25 years (1997–2022). The materials of participants i.e. 33 municipalities from 19 regions were studied. The participants were divided into three size groups by population. In each group, the winner in the final nomination “The Best Strategic Planning System” was determined based on the results in two intermediate nominations – “The Most Stable Strategic Planning System” and “The Best Flagship Project.” The best in the final nomination were the city of Belogorsk (Amur region), Surgut district and Surgut (both are located in Khanty-Mansi Autonomous Okrug – Yugra). The systems of strategic planning of Koltsovo work settlement (Novosibirsk region), Surgut district and the city of Surgut, starting their history since 2002, 2005 and 2004, respectively, are recognized as the most stable ones. In terms of flagship projects, Zadonsky district (Lipetsk region), Michurinsk (Tambov Region) and Novorossiysk (Krasnodar Krai) are in the lead. Based on the materials of the competition, two approaches to strategies’ updating are identified: frequent change of strategies with a short planning horizon and regular updating of a long-term strategy. The flagship projects were grouped by industry orientation. (Most of the projects are presented in the groups “Production”, “Infrastructure, urban environment, transportation”, “Social sphere, culture, sports”; few projects were in the areas of housing and communal services and ecology.) The criteria for the quality of a set of flagship projects are identified: balance of the set of projects by industry, clear relation with the priorities of the strategy, provision of accelerated development in a certain area, concreteness of the results.

ИЗМЕНЕНИЕ ИНДИВИДУАЛЬНЫХ ПАРАМЕТРОВ ВЕГЕТАТИВНОЙ РЕГУЛЯЦИИ КАРДИОРЕСПИРАТОРНОЙ СИСТЕМЫ ПОД ВЛИЯНИЕМ СОЧЕТАННОГО ВОЗДЕЙСТВИЯ ГИПОТЕРМИИ И МЫШЕЧНОЙ НАГРУЗКИ

Interest in the adaptation of the human body to the environment, to the harsh climatic conditions living in the territories of the Far North of Russia and the Khanty-Mansi Autonomous Okrug, is manifested among scientists of various sciences and related disciplines, including biology. The uncertainty and impermanence of homeostatic systems, from the theory of chaos-self-organization, forms a new worldview on the analysis and systematics of complexity systems. Comparison of the changes in the parameters of the cardiorespiratory system in the phase plane at rest, the construction of their graphical portrait and the construction of matrices of paired comparisons of cardiointervals will allow us to determine the depth and nature of the effects of climatic conditions on the body under conditions of hypothermia.

Влияние размещения экономических ресурсов на особенности пространственной организации России

Distribution of economic resources across Russian regions has attracted wide attention due to its significant impact on economic growth potential. Despite numerous approaches to the definition and classification of economic resources, there is no unified comprehensive methodology for assessing their spatial distribution and influence on spatial organisation of the national economy. Therefore, this article aims to study the organisation of the Russian economic space by identifying areas of resource concentration in regions, their spatial relationships and impact on socio-economic development. To this end, index and statistical methods, correlation and regression analysis, cartographic analysis are applied. In accordance with the modern strategic approach to the spatial development of Russia, the study examines the macro-regional level. Natural resources, human capital, and economic development indices were calculated in order to assess the distribution of economic resources and formation of layers (natural, social, productive) of the spatial framework of Russia. These indices are based on socio-economic indicators of Russian regions for 2010 and 2021. To determine areas of resource concentration, a correlation and regression analysis of the influence of indices as a numerical expression of layers of the spatial organisation was performed. A synthesis of the formed layers revealed the following Russian macro-regions of concentration of various economic resources and potential backbone regions of the spatial framework: Central (Moscow, Moscow and Kaluga oblasts), Ural-Siberian (Yamalo-Nenets and Khanty-Mansi Autonomous okrugs, Tyumen oblast), Central Black Earth (Voronezh and Belgorod oblasts), Northwestern (St. Petersburg, Leningrad and Murmansk oblasts). The findings can be used to identify ways to improve the organisation of the Russian economic space, increase the effectiveness of regional development policies and expand the methodology for assessing and forming other spatial layers of the economy.

МОРФОЛОГИЧЕСКИЙ АНАЛИЗ РУСЛА РЕКИ КОНДЫ

The article presents the results of long-term studies of the Konda River basin (Khanty-Mansi Autonomous Okrug). Despite the fact that the Konda is one of the largest rivers in the region, hydrological studies of the river are fragmentary and there are no studies on channel processes. The Konda plays an important role in the social and economic life of the southwestern part of Khanty-Mansi Autonomous Okrug–Yugra as it is one of the main transport routes for interdistrict communication. This article is the first to give a generalized description of manifestations of channel processes – types of channels, bends, conditions and regularities of their development – for the navigable section of the Upper, Middle and Lower Konda (from Lake Tursuntsky Tuman to the mouth). The author discusses the issues related to the development of channel deformations, describes a typical set of morphometric characteristics for different types of channels, classifies them, shows the possibilities of practical use of the research results for forecasting channel deformations. It has been revealed that in the Lower Konda, with a great variety of channel types, the most active deformations are characteristic of channel bends and bends of floodplain branching arms and a bifurcated channel; in the Upper and Middle Konda, having a mainly meandering channel, bank erosion is confined to free channel bends.

НЕЙРОСЕТЕВАЯ МОДЕЛЬ ДЛЯ СЕГМЕНТАЦИИ КОСМИЧЕСКИХ СНИМКОВ В МОНИТОРИНГЕ ФАКТОРОВ ОБЕЗЛЕСЕНИЯ ТЕРРИТОРИИ

The article deals with the important problem of applying neural network models in the tasks of monitoring the condition of forest areas using optical satellite images. Objective. The objective of this research was to develop a neural network model of forest felling suitable for automation of decoding multispectral Sentinel-2 satellite images in forest monitoring tasks in the example of the Khanty-Mansi Autonomous Okrug. Materials and Methods. The basis of the developed model was the forest harvesting satellite images segmentation procedure based on the convolutional neural network of deep learning. Sentinel-2 data interpretation was done using the modern QGIS geoinformation system. Over 990 pairs of multi-temporal space images of the forest territories of Khanty-Mansi Autonomous Okrug in winter (snow) period of 2018–2022 were processed to prepare the training data set. More than 70 000 images of the training data set and corresponding masks of forest cutting contours were generated with these images. Results. As a result of this work, a neural network model of forest felling was created, which implements efficient segmentation of space images, which allowed automating the labor-intensive procedure of interpretation of multispectral Sentinel-2 images in order to identify forest logging contours. The set of training data totally 70 000 frames was divided into the training, validation (test) and test (control) samples, the amount of which for the deve¬lopment of the neural network model of forest felling was 58 000, 10 000 and 3600 frames respectively. The novelty of the model is determined, on the one hand, by the use of winter (snow) satellite images for training the neural network and, on the other hand, by the use of pairs of images acquired before and after forest felling. Recall, Precision and F-measure metrics were used as the criteria to evaluate the accuracy of the trained neural network model, and the values were calculated from the test sample. The calculated accuracy of felling detection using the proposed model on the test sample of data on different metrics reaches 85–87%. Conclusion. The developed neural network model of forest felling can be used for monitoring and mapping of forest resources of the northern forestry territories of Russia using multispectral Sentinel-2 satellite images.

РАЗРАБОТКА ЦИФРОВЫХ ИНСТРУМЕНТОВ ИНТЕГРАЦИИ WELL-BEING В РАБОТУ С ПЕРСОНАЛОМ В АВИАЦИОННОЙ ОТРАСЛИ В ХАНТЫ-МАНСИЙСКОМ АВТОНОМНОМ ОКРУГЕ – ЮГРЕ В УСЛОВИЯХ УДАЛЕННОЙ РАБОТЫ

The study aims to develop tools (including digital ones) for the implementation of well-being technology in organizations based on the findings of a survey on the application of well-being concept and its effect on the employees’ wellness in remote workplaces to ensure the sustaina-ble development of the region (Khanty-Mansi Autonomous Okrug ‒ Ugra). The object of the study is the personnel of air industry organizations in Ugra. The subject of the study is the effect of well-being technology on the air industry personnel’s performance to achieve sustainable development in the region. The study has shown that well-being technology is not quite developed in the Ugra labor market and requires a dramatic change in the set of remote workplaces. Well-being programs will allow employers to improve their employees’ physical and mental health and increase their commit-ment, motivation, and performance, thus resulting in the sustainable development of the region’s economy. The study presents the authors’ logical scheme for the development and implementation of well-being technology in organizations with remote workplaces, as well as possible risks, methods to minimize them, and an approach to supervising and collecting feedback from employees. Chatbot is developed in Telegram as a digital support for the integration of the technology into the employees’ management system.
