Clinical variants of the metabolic syndrome in young people living in the Khanty-Mansiysk autonomous region – Yugra

Currently the “rejuvenation” and an increase in the number of components of the metabolic syndrome (MS) determine its clinical significance in the earlier development of diabetes mellitus, cardiovascular diseases and related complications. Aim of the study was to investigate the features of the MS clinic picture in a population of young men and womenliving in the Khanty-Mansiysk autonomous region – Yugra.Material and methods. The study included 863 young people between 18 and 44 years of age, including 344 men and women with MS and 519 people in the comparison group. Studied subgroups are represented by non-indigenous men and women living in urban and rural areas, and indigenous rural residents. The analysis of MS clinical and laboratory parameters was carried out and its clinical variants in ethnic groups were identified.Results and its discussion. According to the results of the survey of young people with metabolic syndrome, it was revealed that the combination of abdominal obesity and two components of MS were most common in young people with MS (in 50.0 % men and in 55.5 % women). The study defined regression models for each MS group and threshold values for waist circumference were set, which changes in lipid and carbohydrate metabolism were predicted.Conclusions. In groups with MS, hypertriglyceridemia was determined as its most common component. The study identified the most frequent association of abdominal obesity with hyper-LDL cholesterol and hypertriglyceridemia in patients with metabolic syndrome, in ethnic groups, this combination is more common in indigenous rural men (53.3 %) and in non-indigenous urban women (54.3 %).

Comparative analysis of the analytical and numerical methods for calculating the stress-strain state of the near-wellbore zone based on the elastic model taking into account the main structural elements of the well. Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 5, рр.94-102. In Rus. The relevance of the research is caused by the scientific interest in calculating the near-wellbore zone stress-strain state to improve the development of oil and gas fields, to predict the casing stability and the safety of the cement stone. The main aim: based on a comparative analysis of the methods of analytical and numerical simulation of stress calculation near a vertical well using an elastic model, determine the distribution of radial and tangential stresses, compare the accuracy of their calculation by different methods and identify the advantages and disadvantages of each of them. Objects: near-wellbore zone of the terrigenous reservoir of the Achimov deposits of one of the fields of the Khanty-Mansiysk autonomous region. Methods: analytical and numerical finite element methods for stress-strain state calculating of the near-wellbore zone, taking into account the main structural elements of the well and using a linear elastic model. Results. The paper considers the analytical relationships used to calculate the radial and tangential stresses in the casing, cement stone and reservoir rock, as well as the equations used in numerical finite element modeling of stresses near a vertical well. The authors have developed a finite element scheme of the near-wellbore zone, including its main structural elements. The paper introduces the results of calculation of the main components of the stress tensor in the structural elements of the well depending on the radial coordinate for the bottom hole pressure of 20, 40 and 60 MPa. The authors carried out the comparative analysis of the stress calculations results by the methods used. It is shown that the largest discrepancy between the analytical and numerical methods was 2 % that corresponds to radial stresses for the calculation option with a bottom hole pressure of 20 MPa. On average, the discrepancies were: for radial stresses – 0,04 %, for tangential stresses – 0,72 %. It is concluded that when using the model of a linearly elastic medium and under boundary conditions in the form of fixing the model in the upper and lower parts along the normal to the surface, and also without taking into account the pressure distribution in the depression funnel of the model, it is sufficient to use the analytical method of calculation. If it is supposed to use combined boundary conditions, a poroelastic model, taking into account viscoplastic deformations, then it is most preferable to use the numerical simulation method.

The methods for evaluating the efficiency of EOR by SWCTT & PITT tracer tests

Background: In Russia, as well as in the whole world, the number of oil fields that at the last stage of development and characterized by a high water cut of the production is growing. In order to extend the period of their cost-effective operation, a transition from classical waterflooding to the use of chemical methods to enhanced oil recovery (hereinafter - EOR) is required, which implies a preliminary assessment of their potential effectiveness.
 Aim: To select and evaluate chemical compositions, test on core materials with subsequent recommendation of effective compositions.
 Materials and methods: This paper reviews a description of the SWCTT and PITT and evaluation is made of the place of these technologies in the chain of implementation of EOR from laboratory experiments to commercial implementation. The SWCTT method was developed in the 1970s to measure residual oil saturation in the near-wellbore zone after the application of oil enhancement methods. This method is based on the use of partitioning oil-soluble tracer, which forms a secondary non-separable water-soluble traces in the near-wellbore zone due to the hydrolysis process. Evaluation of residual oil saturation is carried out by the time delay in the arrival of the oil and water partitioning tracers.
 Results: As a result of the pilot project, experience was gained in implementing SWCTT technology to evaluate the effectiveness of surfactant flooding at a producing oil well in one of the fields of the Khanty-Mansiysk Autonomous Region.
 Conclusion: The evaluation and effectiveness of the technology with the selected formulations using simulation and the use of alternative SWCTT/PITT tracer methods has been proven by field tests.

Geomechanical modeling and the casing stability analysis in conditions of cement stone partial absence

As part of this work, a numerical finite element model of the near-wellbore zone was developed, including its main structural elements and an area with no cement stone. On the example of the achimov deposits of one of the oil fields of the Khanty-Mansiysk autonomous region, multivariate modeling of the stress-strain state of the near-wellbore zone under conditions of poor-quality cementing was performed. It was revealed that the angular component of stresses has the maximum values in the casing. It is shown that the most probable destruction of the production casing is possible when pressure is not applied in the area of the zone with absence of cement. It is determined that the fracture zones of the column occur for the angle of the area with absence of cement from 25° to 110°, while these areas are characterized by maximum, both tensile and compressive stresses. Keywords: casing; cement stone; elastic-strength properties; near-wellbore zone; numerical model; finite element method; stress-strain state.

Application of the Random Forest classification method for facies zoning according to seismic data

Background. Facial zoning based on seismic data is an important task of dynamic analysis. There are numerous approaches of solving this problem using various algorithms. The most common method is clustering by reflection shape. This approach belongs to unsupervised learning algorithms, due to the mapping of seismic facies is based on the internal data structure and the key feature is the change in the wave packet within the target interval. The disadvantage of this method is requirement of further tying clustering results and geological information. Another way of directed solution of this problem is the use of supervised learning algorithms. This category includes various classification methods that relate to the category of machine learning. In comparison to traditional approaches of seismic facial analysis, this method accounts geological information at the computation stage. Aim. This paper considers the results of a research carried out with the study of the facies structure of the Tyumen formation at a group of fields in the Khanty-Mansiysk Autonomous Region. The Tyumen formation is characterized by the predominance of channel facies associated with the development of complex river systems, which are clearly observed in the dynamic characteristics of the wave field. A complicating factor in the study of these deposits is the rather low coverage of well data, which makes difficult the geological interpretation of the results obtained. Materials and methods. The authors used the Random Forest classification method to deal with the assigned task. The application of the method is considered on the cluster consisting of three seismic surveys obtained at different times. For training, expert marking by area was used based on the distribution of amplitudes along the reflecting horizon. Results. As a result of the research, a probabilistic assessment of the distribution of channel facies was obtained, that is related to the perspective of this type of deposits in the study area. Thus, the authors have developed a methodology that gives an opportunity to obtain an estimate of the probability of the presence of a certain facies using seismic data. Conclusions. The performed study shows the possibility of using the Random Forest classification method to solve the problem of facial zoning.

Large-scale geomorphological mapping of the Malaya Sosva
 state nature reserve

The Malaya Sosva State Nature Reserve is situated in the west of the Khanty-Mansiysk Au-tonomous Region — Ugra. Lake-alluvial, lake-glacial and moraine plains are the prevalent relief’s types on that territory. The main specificity of the reserve’s relief in the central and southern parts is a chain of hilly watersheds — the Malososvinsky Amphitheater. The central, western, and southern parts of the reserve are distinguished by the greatest depth of dissection, while in the northern and south-western regions, a finely divided relief prevails. To study natural conditions and resources of the reserve, a complex mapping was carried out. Based on the results of field researches organized in the summer of 2017, as well as on the data obtained during the processing of topographic maps of scale 1 : 100 000, a Sentinel-2A satellite image, digital terrain models ASTER GDEM, ALOS World 3D and ArcticDEM, the following large-scale maps were constructed for the area under study: hypsometric, the range of dissection and horizontal dissection of the relief, steepness of slopes, as well as a map of «red relief» (Red Relief Image Map). According to those local maps and taking into consideration all the previously issued maps of a smaller scale, a general geomorphological map of the territory of a scale of 1 : 100 000 has been created.

The article discusses issues related to the prevention and counteraction to the spread of the ideology of extremism and terrorism among young people, as the most vulnerable and exposed to external destructive influence of the population category. The question is raised about the need for inter-agency cooperation (specialists of law enforcement agencies, executive authorities, the scientific community, representatives of civil society), aimed not only at prevention, but also at creating a stable civic, legal and social position and responsibility among young people in the interests of ensuring state welfare. On the example of anti-terrorism forum of the Khanty-Mansiysk Autonomous Region, Ugra, possible areas of activity within the framework of interagency cooperation are considered. It is concluded that interagency cooperation is the basis for developing effective ways to prevent the spread of the ideology of extremism and terrorism among young people.

Predictive role of indicators of oxidative metabolism and elemental status in professional drivers of vehicles in the Northern region

Introduction. The predominant source of environmental pollution is motor transport, the release of pollutants which leads to excessive formation of free radicals. The most important metabolic part of the non-specifi c component of the syndrome of adaptation to adverse factors is the activation of free radical oxidation processes that contribute to the mobilization of protective reserves of the body. There is evidence that different groups of the population have different vulnerability to Prooxidant exposure to pollutants. The aim of the study is to establish correlations between the indicators of the pro — and antioxidant system and the elemental status of professional drivers living in the Khanty-Mansiysk Autonomous Region. Materials and methods. 182 male residents (32.6±6.2 years old) of the Khanty-Mansiysk Autonomous Region (KHMAR) were examined: 94 drivers of heavy trucks and fuel trucks and 88 employees. Free radical oxidation products (FRO) were determined in the blood: lipid hydroperoxides (LHP) and thiobarbituric acid active products (TBA-AP) using test kits from BCM Diagnostics (Germany) and AGAT (Russia). Total antioxidant activity (TAA) and thiol status (TS) were determined using commercial kits from Cayman Chemical and Immundiagnostik AG (Germany). The coefficient of oxidative stress (COS) was calculated using the formula: COS=LHP × TBA-AP / TAA × TS. The content of vitamin E was determined on the fl uorometer “Fluorat 02 — ABLF” of the company “Lumex” (Russia), vitamin C — using commercial kits of the company “Immundiagnostik AG” (Germany) on the analyzer of the company “Personal Lab” (Italy). The concentration of macro — and microelements (Ca, Se, Zn, Fe, Pb, Cd) was determined in the samples of AES — ISP and MS — ISP hair in TcMB (Moscow). Statistical processing was performed using the Microsoft Exsel software package and “Statistica 8.0”. For normal distribution, M, m, min, and max values were used. For abnormal distribution, both Me, 25 and 75 PS were used. Correlation relationships were studied using Spearman’s correlation coefficient. Differences at p<0.05 were considered reliable. Results. Drivers compared with employees have signifi cantly higher values of lipid peroxidation, Pb, Cd, Fe ( p <0.001–0.046), against the background of lower indicators of AOS, Ca, Se, Cu, Zn ( p <0.001–0.040). Direct relationships between TAA, vitamins E, C, Se and Zn (r=+0.312–0.802) and inverse relationships between TAA and Pb, Cd (r= –0.623–0.558) were found in drivers of KHMAR with more than 5 years of work experience, which is associated with the development of an oxidative imbalance, which is characterized by an increase in lipid peroxidation products. Conclusions. The relationship between the indicators of the state of oxidative metabolism, the availability of bioelements and antioxidant vitamins involved in the regulation of metabolic processes (p=0.048–0.001) has been established. Direct relationships between the indicators of total antioxidant activity, the glutathione system and the concentration of vitamins E, C, selenium and zinc (r=+0.312–0.802) and inverse relationships between the level of total antioxidant activity, thiol status, and toxic elements: lead and cadmium (r= –0.513–0.604) in the male population of KHMAR were revealed. More pronounced changes in adaptive metabolic reactions in the body of employees of motor transport companies who have a work experience of more than 5 years are associated with the development of an oxidative imbalance, which is characterized by an increase in POL products. The obtained data on the state of the oxidative status of the body of residents exposed to the negative eff ects of a chemical factor can be the basis not only for the formation of risk groups, the development and implementation of a set of scientifi cally-based preventive measures, but also for subsequent evaluation of the eff ectiveness of their use.

SERUM CONCENTRATIONS OF VITAMIN D IN WOMEN LIVING IN THE TYUMEN NORTH

Aim: To assess serum concentrations of vitamin D in women living in the North of the Tyumen region. Methods. 176 women from non-indigenous population living in the cities of the Tyumen region were examined. Of these, 96 were residents of Salekhard (Yamalo-Nenetski Autonomous Region - YаNAO), and 80 - Khanty-Mansiysk (Khanty-Mansiysk Autonomous Region - KHMAO). The mean age of women was 43.9 ± 11,3 years. Serum vitamin D was estimated by chemiluminescent enzyme immunoassay on paramagnetic particles using Architect i2000 SR equipment. Results. The mean values of serum D in both groups of women were significantly lower than the lower limit of physiologically optimal levels. Moreover, the concentration of vitamin D in serum of women in Salekhard (14.5 ± 1.0 ng/ml) was less than a half of the lower limit of the reference values and significantly (p=0.003) lower than the corresponding values in women from Khanty-Mansiysk (18.7 ± 0.9 ng/ml). A moderate deficiency of vitamin D was found in 37.5 % of women in Salekhard and 55.0 % of women in Khanty-Mansiysk while the corresponding proportions for severe deficiency were 22.9 % and 26.2 %. Critical vitamin D deficiency was observed in 36.5 % of women in Salekhard and 10 % - Khanty-Mansiysk. Conclusions. We observed significant differences between the settings in the mean values of serum Vitamin D concentrations. Moreover, greater proportions of women from Salekhard had more pronounced Vitamin D deficiency. Educational programs to inform both doctors and general public about the high frequency of hypovitaminosis D, the role of vitamin D in the protection of public health and the need to prevent hypovitaminosis D and its consequences are warranted to improve the situation.

COMPARATIVE INDICATORS OF IRON AND MANGANESE CONTENT IN THE HAIR OF WOMEN LIVING IN THE NORTHERN REGION WITH DIFFERENT TREATMENT OF DRINKING WATER

Aim: to study the concentration of Fe and Mn in the hair of women living in the cities of Khanty-Mansiysk Autonomous Region (KHMAO) with different treatment of drinking water. Methods. The ultimate composition of hair of 106 women (average age 38,9+11,3 g) - residents of the Northern region, not employed in the manufacturing sector was studied. 50 of them lived in the cities of Nefteyugansk and Nyagan and 56 - in the cities of Surgut and Khanty-Mansiysk. In the cities of Surgut and Khanty-Mansiysk underground water undergoes non chemical treatment, iron removal by the method of deep aeration and decontamination on UV irradiation installations. In the cities of Nefteyugansk and Nyagan water from artesian wells is decontaminated only by baclor. Results. The women living in the cities of Nefteyugansk and Nyagan had significantly higher (p &lt; 0,001) and higher than reference values of Fe (82,3 + 11,4 mkg/g - the norm 7-40) and Mn (11,3 + 1,9 mkg/g - the norm 0,15-2,0) concentrations in the hair compared to women living in cities with high-quality purification of drinking water: Fe (23,6 + 2,2 mkg/g) и Mn (3,1 + 0,2 mkg/g). Iron, getting in to the organism with other pollutants (dietary Fe excess is not negative) also shows the properties of the immunosuppressant. Manganese is considered to be vital and at the same time a toxic element with mutagenic activity and tendency for accumulation. We can assume the best resistance to the adverse effects of oxidative stress in women-residents of KHMAO cities with optimal treatment of drinking water. Conclusions: To correct the microelement status of the Northern region population it is necessary to carry out more research of the environmental objects (in particular water) on the content of heavy metals, pay special attention to quality control of drinking water, and to use the method of microelement status determination of the hair chemical composition as an additional method of assessment of the internal body environment.
