Arterial stiffness and genetic polymorphism of some cytokines in normotensive patients with ankylosing spondylitis

Aim of the study was to identify the incidence of arterial stiffness in normotensive patients with ankylosing spondylitis (AS) in the Trans-Baikal region, to study polymorphism of genes for some cytokines and prognostic factors for increased arterial stiffness in this disease. Material and methods. We examined 100 patients with AS, natives of the Transbaikal region, HLA-В27 positive and 100 healthy controls, HLA-B27 negative; all included in the study were Caucasian. Arterial hypertension was an exclusion criterion. Determination of single nucleotide polymorphisms of the genes IL1B (‒31T/C, rs1143627), IL10 (‒592C/A, rs1800872), IL10 (‒819C/T, rs1800871), TNF (‒308G/A, rs1800629) was carried out in all patients with AS and healthy individuals. 74 patients with AS and 40 patients in the control group underwent applanation tonometry using SphygmoCor (AtCor Medical, Australia). Results. Pulse wave velocity on the carotid-femoral segment in patients with AS was 6.5 [4.1; 11.7] m/s, in the control group – 5.2 [3.9; 7.0] m/s (p = 0.0001). In 18 patients with AS (24.32 %) it was more than the age norm, these patients made up the group with elevated arterial stiffness. In patients with AS, carriage of the homozygous AA genotype of the IL10 gene (rs1800872, ‒592C/A) was 2.18 times more common, the homozygous GG genotype of the TNF gene (rs1800629, ‒308G/A) was 1.23 times more common, and the heterozygous ST genotype of the IL10 gene (rs1800871, ‒819C/T) was 1.5 times more common than in the control group. Prognostic factors for increased arterial stiffness in patients with AS were carriage of the IL10 rs1800871 polymorphism, age, and the radiological stage of changes in the sacroiliac joints. Conclusions. Increased arterial stiffness was detected in 24.3 % of normotensive patients with AS. The CT genotype of the IL10 gene (rs1800871, ‒819C/T), AA genotype of the of the IL10 gene (rs1800872, ‒592C/A), the G allele and the GG genotype of the TNF gene (rs1800629, позиция ‒308G/A) are associated with the development of AS in Caucasians. Multivariate regression analysis identified clinical and genetic factors that predict an increase in arterial stiffness in patients with AS, natives of the Trans-Baikal Territory.

Старомонгольская письменность в Байкальском регионе на современном этапе: курс на ревитализацию?

This paper aims to provide an analysis of the development of the Mongolian script in the sociocultural context of the Baikal region in modern times. The main purpose of this article is to characterize the key trends in society from the point of view of sociolinguistic processes. Materials and methods. The research is based on a thorough examination of official data from the Government of the Republic of Buryatia, government departments of the Irkutsk region and Transbaikal region, as well as publications in the media and field materials gathered through an expert survey of heads of educational centers and language activists. The authors have adopted a systematic approach and applied a range of general scientific and special methods, including comparative historical and statistical methods, to conduct this study. Results and conclusions. It has been revealed that the Mongolian script has significant role in performing various socio-cultural functions. Mongolian script has gained widespread popularity in the form of calligraphy in the Baikal region. Furthermore, the language is deeply embedded with ethno cultural symbolism, making it a valuable source for the development of the Buryat language and culture as a whole. There is a growing interest in analyzing the language situation in Mongolia and the Inner Mongolia Autonomous Region of the People’s Republic of China, particularly in terms of the implementation of state language policy in perspective. The status and functional role of Mongolian script in these regions are of utmost importance in understanding its impact on the overall language landscape.

ИНДИКАТОРЫ СОСТОЯНИЯ ПРОДОВОЛЬСТВЕННОГО ОБЕСПЕЧЕНИЯ И УРОВНЯ ЖИЗНИ НАСЕЛЕНИЯ ДАЛЬНЕВОСТОЧНОГО ФЕДЕРАЛЬНОГО ОКРУГА

In developed countries of the world, human capital is recognized as the main most valuable resource, which is the principal factor in the development of any territory. The life and health of people is the most important asset of any nation. The population of Russia has been steadily decreasing in recent decades due to natural and migration decline. In the Far Eastern Federal District (FEFD), the demographic situation is especially acute: over the last three decades, the population has decreased by 22,3 %. The main reason is the rapid decline in the standard of living of the population. In turn, the demographic situation is significantly influenced by housing conditions, the level of food supply and the quality of nutrition. The population of the Far Eastern regions eats irrationally: people compensate for the energy and nutrients not received in protein foods and vegetable and melon products by excessive consumption of baked goods, pasta and cereals. This diet contributes to an increase in morbidity and a reduction in life expectancy. These problems are especially acute in regions with high poverty, low living standards and low social productivity. The most problematic in terms of the standard of living of the population are the Jewish Autonomous Region, the Trans-Baikal Region and the Republic of Buryatia: the median per capita cash income of residents of these regions allows them to buy no more than 4 minimum sets of food per month (in Russia as a whole – 5,7 sets), housing conditions are the worst in the Far Eastern Federal District. To improve the quality of food supply and living standards of the population in the regions, it was proposed to strengthen the social responsibility of the state and take comprehensive measures to increase real cash incomes; development of social entrepreneurship and social partnership; restoration and development of production in the regions of necessary products - milk, eggs, melons and vegetables. This will require significant investment in the rural economy of the Far Eastern regions to ensure growth in production volumes and development of human capital.

Development of fluvial‐lacustrine systems in the rift basins fostered Jehol Biota origin: Palaeobiogeographic insights on Dabeigou‐type ostracod fauna

The Lower Cretaceous Dabeigou Formation (135–130 Ma) in the Luanping Basin, associated with its contemporary strata in northeastern China, contains the earliest documented fossils of the Jehol Biota. This includes the Luanpingella—Eoparacypris—Ocrocypris ostracod assemblage, referred to in this study as the Dabeigou‐type ostracod fauna (DOF). Ostracods, which are small (0.5–2 mm) aquatic crustaceans, are abundant and easily preserved as fossils. Outlining a clear palaeobiogeographic range of the DOF can help expand the distribution range of the early Jehol Biota, providing valuable information on its origin. Results show that the DOF is mainly distributed in a series of rift basins along the Yanliao area of China to the eastern Transbaikal region of Russia, with a roughly narrow north‐south distribution. Rift basin development in the eastern part of the North China Craton, combined with humid climatic conditions, provided a suitable environment (e.g., fluvial‐lacustrine systems) for the emergence of the Jehol Biota.

Reproductive ability and milk productivity of mares of different genealogical lines of Argaleisky type of Transbaikal breed

Productive herd horse breeding in Transbaikal region is one of the traditional branches of animal husbandry. The problem of preserving and improving local (aboriginal) horse breeds in our country is extremely important for their eff ective economic use and maintaining the diversity of the original gene pool of farm animals. Therefore, line breeding is an important aspect of horse breeding. The purpose of the research was to study the reproductive ability and milk productivity of mares of diff erent lines of Argaley type of Transbaikal breed. Research was carried out at the APC “Plemzavod imeni Kalinina” in the Aginsky district of the Trans-Baikal Territory. The objects of the study were mares of Transbaikal breed of Argaley type of diff erent genealogical lines origin, the age of the mares was 8–9 years after 4–5 foalings. The conformation and constitutional features and live weight of mares depending on their genealogical lines origin have been presented in the article. The average fertility performance rate for mares of different lines was 93,7 %, with foaling being 98,8 %. The greatest live weight was in mares belonging to the line Argali. It exceeded the indicators of herdmates from the lines Premier, Chetkiy and Kagor by 20,0; 15,0, 10,0 kg, respectively. During 5 months of lactation, mares of the line Argali produced 1854,0 kg of milk with an average daily milk yield of 12,36 kg. Mares of the line Argali over 5 months of lactation were superior to herdmates of other lines in terms of milk yield by 459,0; 336,0 and 223,5 kg and average daily milk yield by 3,06, 2,24 and 1,49 kg, respectively. It has been established that the physicochemical composition and environmental safety of milk from mares of the different lines of Argaley type of Transbaikal breed indicate its fairly high nutritional value.

Polymorphism of serum blood proteins of herd horses (<i>Equus ferus caballus</i>) of the transbaikal breed

The results of a study of the genetic diversity of the Transbaikal horse breed based on the polymorphism of whey proteins TF, Es, and ALB in four herds of the Transbaikal region are presented. The Transbaikal horse belongs to the ancient aboriginal breeds and is most adapted to the local climatic conditions of dry, hot summers and frosty winters with little snow. It is unpretentious, hardy, and has a strong constitution. Research is aimed at preserving the breed’s genetic diversity by studying polymorphic variants of whey proteins, which are reliable genetic markers due to their codominant inheritance and comprehensive polymorphism. In the albumin locus, two alleles and three genotypes were identified. In the esterase locus, there are six alleles and 13 genotypes. In the transferrin locus - 7 alleles and 18 genotypes occur with different frequencies in the studied herds, which makes it possible to characterise their genotypic characteristics. Rarely encountered genotypes of the transferrin locus (less than 10 %) include eight genotypes: TFDD, TFDH, TFDI, TFDR, TFFI, TFFM, TFOR, TFR; esterase locus – 6 genotypes: EsGI, EsHH, EsHI, EsHO, EsII, EsGI. Based on the frequency of genotypes and alleles, homozygosity was calculated for each whey protein system and for the entire sample from the herd, the level of which ranges from 7.87 to 12.25 %. The overall homozygosity rate varies from 34.35 to 43.36 %, and the number of effective alleles (Na) in all herds is almost the same (2.30–2.91). Genetic variability ranges from 56.96–63.74 %. The index of gene similarity between herds is at the level of 0.8439–0.9058. The analysed herds form two subclusters: the first includes horses from the APC (Agricultural Production Cooperative) Livestock Breeding Farm named after. Kalinin and SPK “Rassvet”. In the second - animals from APC (Agricultural Production Cooperative) “Livestock Breeding Farm “Rodina” and AC (Agricultural Cooperative) “Taptanay”.

Сравнительный анализ итогов выборов в региональные парламенты Республики Бурятия и Забайкальского края в 2023 г.

The article provides a comparative analysis of the main results of the elections to the regional parliaments of the Republic of Buryatia and the Transbaikal Region. The conducted analysis actualizes the study. The object of the study is the regional election campaign for the election of deputies of the regional legislative authorities of the Republic of Buryatia and the Transbaikal Region. The purpose of the study is a comparative analysis of the course and results of elections to regional parliaments, identification of common and distinct features and peculiarities. In accordance with the set goal, the tasks are defined: to identify the main features of the indicators for the nomination of candidates for the post of deputies of regional legislative bodies in the Republic of Buryatia and the Transbaikal Region; to determine the main features of the election campaign in the Republic of Buryatia and the Transbaikal Region. The methodological basis of the research is the institutional approach. As the authors note, there have been quite significant changes compared to the 2022 elections. Firstly, the composition of participants in the electoral competition has changed, in particular, not only the share of non-party nominees has decreased, but also the number of candidates from non-systemic political parties. Secondly, there has been a consolidation of society, as a result of which the positions of the “party of power” strengthened and the possibilities of minority parties weakened. This has also affected the governance of the parliament, which has become more “obedient”. At the same time, each region has its own characteristics. In Buryatia, compared with the Transbaikal Region, a much smaller number of political parties participated in the electoral race and the possibilities of the “party of power” are somewhat higher. At the same time, the New People party joined the parliament in the parliamentary elections in Buryatia, but not in Transbaikalia. These and other circumstances allow us to speak about the beginning of a new stage in the development of political parties, where the positions of the “party of power” are once again strengthening and opposition forces are weakening. It is concluded that the role of regional branches of political parties in the political space of Russian regions is increasingly being minimized.

Impact of environmental change on crop yield case study of the Trans-Baikal region

This study analyzes the impact of climatic conditions on the development of grain and leguminous crops in the Trans-Baikal region. Insufficient precipitation, droughts, early frosts, and a short growing season limit the choice of crops suitable for cultivation in the region. Grain crops, which occupy the largest share of sown areas, are chosen as the object of research. Based on theoretical and economic analysis and data on sown areas, yield, average temperature, and precipitation during the growing season, a regression model has been constructed to assess the impact of climatic factors on the gross grain harvest in the Trans-Baikal region.

Структурные изменения в управлении медицинским делом восточносибирских окраин как результат ревизионной поездки генерал-губернатора Н. Н. Муравьёва-Амурского

This article examines the transformations that followed the inspection of Governor General N. N. Muravyov in the entrusted territories. Against the backdrop of the global task of restructuring the administrative-territorial system, changes have occurred in the management of social issues, in particular, medical affairs. Thus, the simplified management system of the Yakut, Kamchatka, Transbaikal regions, providing for the independence of governors, contributed to the introduction of the positions of medical inspectors and the formation of a staff of medical officials. The most significant changes took place in the medical sphere of the Trans-Baikal region, where medical care for the military contingent began to form.

«Сказание о хождении в Тибет пандита-хамбо-ламы Заяева из цонгольского рода» как источник по истории буддизма

The history of Buddhism and the initial period of its spread in Transbaikalia in the XVII-XVIII centuries are insufficiently studied due to the lack of archival materials and sources, while the surviving historical records provide different information about some events, such as the year of construction of the first Buddhist temple and the first sermon, the years of D.-D. Zayaev's life. The earliest extant sources are "Autobiography" and "Travel Notes" written by D.-D. Zayaev in 1768. They contain valuable information not only about the history of Buryat Buddhism, but also about the life and activities of D.-D. Zayaev (1711-1776), the first Buryat pandita Khambo-Lama, whose name is associated with the beginning of the spread of Buddhism among the Buryats and its institutionalization in the Russian Empire, but also with the description of his pilgrimage to Tibet. In this regard, in order to clarify some dates on the early history of Buryat Buddhism, texts related to him have been searched for and analyzed in the funds of the Center of Oriental Manuscripts and Xylographs (CVRK) of the Institute for Mongolian, Buddhist and Tibetan Studies of the Siberian Branch of the RAS. It was established that of the six sources found, the most informative work is "The Legend of the Tsongol Kin Pandita Khambo-Lama Zayaev's Journey to Tibet" in the Old Mongolian script, stored in the Mongolian collection of the CVRK. As a result of the study, it was revealed that this work is a late manuscript consisting of the "Travel Notes", the Biography of D.-D. Zayaev and of an anonymous manuscript containing a brief description of Buddhist sacred places and shrines in India, Nepal, Tibet and Mongolia, what has determined its structure consisting of 3 parts. It was found out that this manuscript contains information about the socio-economic situation of the population of Tibet and neighboring countries, as well as information about the history of Buddhism in Transbaikal region in the middle of the XVIII century. It testifies to Russia's geopolitical interests in this region of Inner Asia and the peoples living there, as the author reports, saying that it was written at the behest of Catherine II, who outlined a range of issues: "to describe what I’ve seen on my way to Tibet, the length of the road and distance, as well as about the customs and habits of people". The unique historical information preserved by the Buryat pilgrim and the Russian citizen D.-D. Zayaev is also relevant for conducting comparative studies of the phenomenon of modern pilgrimage that is becoming popular not only for believers but among ordinary lay population.

Геоэкологическое картирование застройки на паводкоопасных территориях городов Шилки и Нерчинска Забайкальского края с использованием спектрального индекса NDBI и нейронной сети

At all times, the problem of floods has been relevant due to their destructiveness, frequency and poor predictability. The situation is complicated by the fact that floodplains are used for economic, recreational and other activities, thereby exposing the risk of destruction and degradation of any objects and human waste products during floods. Therefore, mapping and spatiotemporal monitoring of flood-prone areas in order to analyze and predict the likely material and economic damage to facilities of economic activity from the threat of floods is an urgent scientific problem that can be solved by geographic information systems using satellite data processed by spectral indices and convolutional neural networks. The object of the study is the flood-prone territories of Shilka and Nerchinsk (Transbaikal Region). The purpose is to assess the accuracy of economically developed territories decryption in flood-prone areas of Shilka and Nerchinsk in order to determine the effective threshold for separation of the studied facilities. Research objectives are as follows: collection and formation of an archive of Earth remote sensing data of the Landsat-8 OLI program; inference of satellite images on a neural network and their use as a reference image; calculation of NDBI spectral indices based on Landsat-8 data; determination of the areas of buil­­t-up and economically developed territories in the images; assessment of the accuracy and comparative analysis of the results of the development facilities allocation and economic activity; identification of advantages, disadvantages, applicability limits of the methods used to decrypt buildings and objects of economic activity in flood-prone areas. The accuracy and reliability of the results of the decrypting buildings and objects of economic activity by calculating the NDBI spectral index, the inference of a convolutional neural network according to Landsat 8 OLI data in flood-prone areas of Shilka and Nerchinsk have been evaluated. The most effective methods, parameters and thresholds for decrypting buildings and objects of economic activity have been determined in order to monitor the development of flood-prone areas and control the flood-prone situation.

Технология переработки сухих отходов сорбции и растворов хлоридов сурьмы

Reducing the loss of valuable components during the processing of complex gold-antimony ores, increasing the extraction of antimony during the flotation of sulfide minerals, is an urgent scientific problem. The aim of the study is to maximize the extraction of gold and antimony from dry sorption waste after gold cyanidation, and to improve the reagent regime of the antimony mineral flotation process. Research objectives are as follows: evaluation of the technology efficiency for processing dry sorption waste; extraction of gold from the cake of acidic leaching of antimony; production of various antimony-containing products from solutions of antimony chlorides; study of the possibility of replacing lead with a mixture of zinc and copper cations to hydrophobize the surface of antimony sulfide minerals during flotation. The object of the research is man-made and natural mineral raw materials containing gold and antimony. The following research methodology and methods are used: information analysis, evaluation of existing scientific developments, methods of theoretical and experimental research. A new technological solution has been proposed: acidic (a mixture of hydrochloric acid and hydrogen hydroxide) hydrometallurgical technology for processing dry sorption waste in order to extract gold and antimony. Acid treatment makes it possible to completely transfer antimony into solution, significantly improves the quality of the cake for subsequent cyanidation and gold extraction, reduces the volume of material for processing by cyanidation, and simplifies cyanidation technology. Sb2S3 activation and the possibility of lead (Pb(NO3) replacement have been studied 2) a mixture of zinc and copper (ZnSO4 and CuSO4) during the flotation of antimony ores from the Khipkoshinsky deposit in the Transbaikal Region. This has made it possible to create favorable conditions for interaction with xanthogenate and hydrophobize the surface of sulfide minerals. Theoretically, hydrogen sulfide substitutes such as NaCNS, KCNS, CuCNS for use in the flotation process were evaluated.

Граф Муравьёв-Амурский и Забайкалье

Governor-General of Eastern Siberia N. N. Muravyov proposed to focus on solving continental problems, leaving Alaska to America. He developed a plan for the development of the Amur, choosing Transbaikalia as a springboard for solving socio-political and economic problems, where the Trans-Baikal Region was created with the center in Chita with the statute of the city, the TransBaikal Cossack army, the registration of peasants to factories was canceled. Chita began to play the role of the Eastern Kronstadt and the upper Amur pier. Since 1854, Amur expeditionary raftings began with the Ingoda or the Shilka, ensuring the movement of military personnel, mainly from trans-Baikal Cossacks, weapons and food to the mouth of the Amur. During the first four years of rafting, Muravyov mastered and began to populate the Amur banks with migrant peasants. He managed to repel the attack of the Anglo-French squadron and convince the Chinese authorities of Russia's peaceful and friendly intentions. Friendly agreements were concluded with China – the Aigun, Tianjin and Beijing agreements on the delimitation of the territory along the Amur and Ussuri. For mastering the Amur River, according to the rescript, Muravyov was granted by Alexander II the title of count and the honorary name Amur. In modern scientific and educational literature, there is a clear underestimation of the activities of Count N. N. Muravyov-Amursky.

Региональная культура как потенциал развития туризма в российско-китайском приграничье: от теоретической объективации к вопросам новых реалий

The article focuses on cultural and civilizational potential of Russian eastern borders and China border regions. The subject of this article today seems to be particularly relevant in the context of two circumstances: firstly, tourist contacts have undergone significant transformations in the context of the COVID-19 pandemic, and secondly, the aggravating situation with the emergence of barriers to entry into the European tourism space makes China one of the most attractive regions for tourism development. The very concept of "border", regardless of the above, appears here not as a certain outpost, but as a unique sociocultural space where regional culture functioning is mediated by the influence of three cultural dimensions (national, local, foreign). The case of border regional pair the Transbaikal Region, Russia and North-East China shows the features of their culture’s interaction, which are of interest for integration into the processes of border tourism formation and development. The identified problems in the border tourism sector development are proposed to be solved, among other things, by updating the work on online platforms, which act as a modern space for the concentration and accumulation of tourist content in the era of digitalization. A possible solution to the above issues on the basis of the original "dialogism of border area regional cultures" model, its integration into the concept of tourism development in the border areas is indicated, as well as the vector of modern state policy regarding the development of tourism initiatives in the Russian-Chinese border area.

The article explores newspaper The Eastern Review’s point of view in connection of the Amur General Government creation. The edition, giving floor to all the participants of the discussion regardless of their judgment, nevertheless, definitely stated its own look at the problem: need for new General Government including Transbaikal Region and uselessness of Eastern Siberian General Government.

Ecological study of atmospheric air on the territory of the Trans-Baikal Territory “Charsky territorial mountain-metallurgical complex”

The article describes the impact on the atmospheric air, which are acute negative nature of mining enterprises and their infrastructure industries of the North of the Trans-Baikal Territory, which actualizes this problem in society. The object of the study is the territory of the advanced development of the Trans-Baikal region “Charsky territorial mountain-metallurgical complex”. The subject of the study is the current ecological state of atmospheric air. The aim of the study is to analyse the negative impacts of mining production, as well as the accompanying infrastructural factors that have a complex impact on the ecology of the atmospheric air in the northern territory. The research tasks are reduced to the identification of sources and types of atmospheric air pollution during the quarrying of ore, its enrichment, and the impact of the supporting industries of mining industrial production. The methodological basis of the study is integrated, structural, factological principles and approaches. The article uses general methods of research (analysis, synthesis, generalization), as well as private-scientific-factor analysis, which means the methodology of complex and system study of interaction of factors on the size of the effective indicators and others. The factor analysis of published and stock materials on title issues allowed to perform a complex analysis of the influence of the main factors of quarry production on the air of the adjacent territory. Features of atmospheric air pollution during the quarrying of sites, ore enrichment and work of service industries have been identified. Identified toxic pollutants cause the occurrence and exacerbation of various human diseases. The urgency of solving the issue of dust suppression during the quarry development of the deposits of the Udokan hearth of mineral resources, as well as the issue of transferring quarry vehicles to the consumption of replenished fuel, i.e. electricity - replacing diesel dump trucks with dump trucks powered by a contact network (trolleybuses, diesel trolleybuses, trolleynoac-cumulative). The urgency of solving the issue of dust transfer at the quarrying development of deposits of the Udokanskiy hotbed of mineral resources was substantiated, as well as the development of the question of the transfer of career vehicles for the consumption of renewable fuels, t. e. Electric power - replacement of diesel pit dump trucks with dump trucks powered by a contact network (trolley vehicles, diesel-trolley-vehicles, troll-batteries).

Soils of Lakeside Depressions of Pulsing Chloride Lakes of Internal Runoff in Central Asia: Morphology, Physical-Chemical and Geochemical Features

Data on saline soils of drainless lakeside depressions, which are formed in areas of extra continental climate with a cyclic 25–30-year change in the level of lakes within the arid and humid climatic phases, were obtained first. Different types of soils are shown to be formed on the landscapes adjacent to highly mineralized chloride lakes of southeastern Trans-Baikal Region: on superaqueous–subaqueous positions– gleyic solonchaks (Gleyic Solonchak (Loamic, Chloridic)); on superaqueous – humus–gley saline soils (Calcaric Mollic Gleysol (Arenic, Endosalic, Sodic)); on eluvial-superaqueous – light-humus saline soils (Fluvic Kastanozem (Epiarenic, Amphiloamic, Sodic)). Salinity degree of the soils under the study is different. Salinity chemistry is sodium taking into account cations. Anion content in solonchaks and upper horizon of humus-gley soil is mostly chloride. Soda-chloride and chloride-soda anion composition prevail in other soils. Gleyic solonchaks have strongly alkaline pH values, high content of carbonates, and a sharp dominance of Na+ among exchangeable cations. Many chemical elements are concentrated in the solonchakous horizon (Sr, S, Li, Mg, Ca); a high content of As is a regional feature. The humus-gley saline soil has the same properties as the light-humus saline soil in terms of physico-chemical parameters, and in terms of elemental composition and texture as solonchaks. This is due to it functions periodically in a semihydromorphic or hydromorphic regimes when changing the arid and humid phases. The high level of groundwater contributes to the enrichment of soils with the elements typomorphic for lake waters. The paleohydromorphic stage of development has been established to be recorded in lower layers of light-humus saline soil in the form of a high content of easily soluble salts and carbonates. The geochemical specialization of soil-forming rocks is associated with the significant accumulation of As, as well as concentration of Li, Ba, and Pb. It was also revealed that low Ca/Sr ratio is their geochemical feature. The use of cluster analysis of indicators of soils under the study revealed that both dynamic and stable soil parameters are reflected in humus-gley soil and it is recommended for monitoring of the dynamics of endorheic lakeside ecosystems in Central Asia with cyclic climatic phases.
