Resumen:The article considers the findings of hygienic assessments of educational conditions in urban and rural schools in Mongolia and socio-economic conditions of living of schoolchildren and analysis of anthropometric measurements of schoolchildren aged of 7-16 years in relation to the assessment of harmonicity of their physical development. Hygienic conditions in Mongolian schools are characterized by improper organization of the educational - accomplishment process, high occupancy rate in classes causing insufficient space for a pupil and disconformity of school furniture parameters of school desks and chairs to growth and age requirements of pupils. Comparative assessment of socio-economic factors revealed (выделено автором) that the majority (84.1%) of rural pupils reside in uncomfortable houses and gerdwellings, 58.5 % - in large families with many children, 46.3 % - in families with poor living conditions. There were obtained data about differences in physical development of urban and rural schoolchildren pronounced with age by the gain in the number of children with disharmonious development and children with lower physical indices of the development, delayed by 1-2 years appearance of the crossing of growth and growth shift typical for rural children in comparison with their urban counterparts. According to results of multivariate regression analysis most significant factors for the formation of physical development of school children in descending order are academic workload, the place of residence, the number of children in the family, uncomfortable living conditions, household income and parent's education. In the presence of these factors, the risk of the formation of disharmonious physical growth of school children increases by 1.8-2.8 times. The probability of the risk offormation of disharmonious physical development of schoolchildren living in rural areas was found to be by 2.5 times more than for their urban counterparts. The results can be usedfor scientific substantiation and development of targeted health measures.

Resumen:Selenium is one of the essential elements which adequate consumption is strictly necessary for human health. Despite unfavorable geographical position of Mongolia and registered cases of selenium deficiency diseases among domestic animals in some provinces of the country there are still no concrete data of selenium content in objects of the environment in this region. The aim of the present work was the evaluation of selenium consumption levels by adults from different provinces of Mongolia and the development of methods of prophylactic for the selenium status optimization. Detection of selenium deficiency in Mongolia was caused by inadequate selenium content in foodstuffs. Determined mean consumption levels were equal to 41.8±4.9 µg/day for males and 34.1±3.1 µg/day for females. The main reason of low selenium content in the diet was its deficiency in native foodstuffs: selenium concentrations in meat of domestic animals µg/kg d.w.) reached 109-296 in beef, 94-200 in mutton, 120-225 in horseflesh and 124-197 in goat's flash, values did not differ between each other statistically (p>0.05). The exception were samples of horseflash with selenium concentration exceeding 400 µg/kg d.w. from Gov-Altai province. Selenium content in wheat was in the range 6-36µg/kg d.w., with the lowest levels in Dornod, Ucs and Selenge provinces. Selenium content in eggs was equal 6.7-7.8 µg/egg. The correction of selenium deficiency is recommended to achieve using preparations of Astragalus Mongolicus from Bulgan province with selenium concentration 278±26µg/kg d.w. Besides this utilization of Mongolicum Tricholoma Mushrooms (from the vicinity of Ulaanbaatar and from Zavkhan province) seems to be highly promising due to high selenium concentrations (616±26 µg/kg d.w. and 352±17µg/kg d.w. respectively).

Resumen:In Russia, the species of the genus Iris L., series Lacteae Doronkin, the taxonomic structure of which still remains controversial, are found in the south of Siberia and the Russian Far East, as well as in other regions of Asia. Sequence analysis of three chloroplast DNA regions (rps4, trnL­trnF, and trnS­trnG) shows that, in Russia and adjacent countries, there are two genetically and geographically isolated Lacteae species. I. oxypetala Bunge grows in the south of the Russian Far East, and I. lactea Pall. grows in Siberia, Mongolia, and Kazakhstan. Genetic differentiation between the populations of I. lactea is extremely low and statistically insignificant (the fixation index ΦST = 0.057, P > 0.05), pointing to the unity of the gene pool and the absence of other Lacteae species in this area.

Resumen:For many years a team of specialist Gynaecologists and Anaesthetists from The Women's Hospital in Melbourne have travelled to the beautiful, nomadic land of Mongolia. They have helped train Mongolian doctors in advanced practices related to laparoscopic-gynaecological surgery and anaesthesia, facilitating a number of ground-breaking 'firsts' in hospitals across several regions of the country. The role of nurses in this expedition was never established, and in 2015 a team of perioperative clinical nurse specialists joined the medical team to Mongolia for the first time.

Resumen:Climate change affects the timing of phenological events, such as the start, end, and length of the growing season of vegetation. A better understanding of how the phenology responded to climatic determinants is important in order to better anticipate future climate-ecosystem interactions. We examined the changes of three phenological events for the Mongolian Plateau and their climatic determinants. To do so, we derived three phenological metrics from remotely sensed vegetation indices and associated these with climate data for the period of 1982 to 2011. The results suggested that the start of the growing season advanced by 0.10 days yr-1, the end was delayed by 0.11 days yr-1, and the length of the growing season expanded by 6.3 days during the period from 1982 to 2011. The delayed end and extended length of the growing season were observed consistently in grassland, forest, and shrubland, while the earlier start was only observed in grassland. Partial correlation analysis between the phenological events and the climate variables revealed that higher temperature was associated with an earlier start of the growing season, and both temperature and precipitation contributed to the later ending. Overall, our findings suggest that climate change will substantially alter the vegetation phenology in the grasslands of the Mongolian Plateau, and likely also in biomes with similar environmental conditions, such as other semi-arid steppe regions.

Resumen:OBJECTIVE: Our previous 2005-2009 molecular epidemiological study in Mongolia identified a hot spot of HIV-1 transmission in men who have sex with men (MSM). To control the infection, we collaborated with NGOs to promote safer sex and HIV testing since mid-2010. In this study, we carried out the second molecular epidemiological survey between 2010 and 2016 to determine the status of HIV-1 infection in Mongolia. METHODS: The study included 143 new cases of HIV-1 infection. Viral RNA was extracted from stocked plasma samples and sequenced for the pol and the env regions using the Sanger method. Near-full length sequencing using MiSeq was performed in 3 patients who were suspected to be infected with recombinant HIV-1. Phylogenetic analysis was performed using the neighbor-joining method and Bayesian Markov chain Monte Carlo method. RESULTS: MSM was the main transmission route in the previous and current studies. However, heterosexual route showed a significant increase in recent years. Phylogenetic analysis documented three taxa; Mongolian B, Korean B, and CRF51_01B, though the former two were also observed in the previous study. CRF51_01B, which originated from Singapore and Malaysia, was confirmed by near-full length sequencing. Although these strains were mainly detected in MSM, they were also found in increasing numbers of heterosexual males and females. Bayesian phylogenetic analysis estimated transmission of CRF51_01B into Mongolia around early 2000s. An extended Bayesian skyline plot showed a rapid increase in the effective population size of Mongolian B cluster around 2004 and that of CRF51_01B cluster around 2011. CONCLUSIONS: HIV-1 infection might expand to the general population in Mongolia. Our study documented a new cluster of HIV-1 transmission, enhancing our understanding of the epidemiological status of HIV-1 in Mongolia.

Resumen:Little is known on members of the genus Amycolatopsis inhabiting acidic habitats. In this study, a moderately acidophilic Amycolatopsis strain, designated 2-5T, was isolated from coal mine soil, and subjected to a polyphasic taxonomic characterization. Analysis based on 16S rRNA gene sequences indicated that the strain was most closely related to the type strain of Amycolatopsis bartoniae, sharing 99.30 % similarity, while similarity to all other Amycolatopsis species was less than 97 %. The DNA-DNA relatedness between the new isolate and the type strain of A. bartoniae was 56.5±0.7 %. The optimal pH range of the isolate for growth was 5.5-6.0, but growth also occurred at pH 4.5 and 7.5. The isolate tolerated up to 6 % (w/v) NaCl (optimum, 0 %), and the temperature range for growth was 15-40 °C (optimum, 30 °C). The isolate was able to utilize most substrates tested for sole carbon sources, showing its metabolic versatility. The isolate exhibited antimicrobial activity against Serratia marcescens and weak antifungal activity against Fusarium proliferatum. The chemotaxonomic profiles of strain 2-5T included polar lipids containing phosphatidylethanolamine, phsphatidylmethylethanolamine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol dimannosides, fatty acids containing C17 : 1ω6c and iso-C16 : 0 as the major components, MK-9(H4) as the predominant menaquinone, and meso-diaminopimelic acid and arabinose, galactose, glucose and ribose as the diagnostic diamino acid and sugars in the cell wall. The combined phenotypic, chemotaxonomic and genotypic analyses clearly indicated that the isolate merits recognition as represnting a novel species of Amycolatopsis, for which the name Amycolatopsis acidiphila sp. nov. is proposed. The type strain is 2-5T (=KCTC 39523T=JCM 30562T).

Resumen:BACKGROUND: Quantifying carbon (C) dioxide exchanges between ecosystems and the atmosphere and the underlying mechanism of biophysical regulations under similar environmental conditions is critical for an accurate understanding of C budgets and ecosystem functions. METHODS: For the first time, a cluster of four eddy covariance towers were set up to answer how C fluxes shift among four dominant ecosystems in Mongolia - meadow steppe (MDW), typical steppe (TPL), dry typical steppe (DRT) and shrubland (SHB) during two growing seasons (2014 and 2015). RESULTS: Large variations were observed for the annual net ecosystem exchange (NEE) from 59 to 193gCm , though all four sites acted as a C source. During the two growing seasons, MDW acted as a C sink, TPL and DRT were C neutral, while SHB acted as a C source. MDW to SHB and TPL conversions resulted in a 2.6- and 2.2-fold increase in C release, respectively, whereas the TPL to SHB conversion resulted in a 1.1-fold increase at the annual scale. C assimilation was higher at MDW than those at the other three ecosystems due to its greater C assimilation ability and longer C assimilation times during the day and growing period. On the other hand, C release was highest at SHB due to significantly lower photosynthetic production and relatively higher ecosystem respiration (ER). A stepwise multiple regression analysis showed that the seasonal variations in NEE, ER and gross ecosystem production (GEP) were controlled by air temperature at MDW, while they were controlled mainly by soil moisture at TPL, DRT and SHB. When air temperature increased, the NEE at MDW and TPL changed more dramatically than at DRT and SHB, suggesting not only a stronger C release ability but also a higher temperature sensitivity at MDW and TPL. CONCLUSIONS: The ongoing and predicted global changes in Mongolia likely impact the C exchange at MDW and TPL more than at DRT and SHB in Mongolia. Our results suggest that, with increasing drought and vegetation type succession, a clear trend for greater CO emissions may result in further global warming in the future. This study implies that diverse grassland ecosystems will respond differently to climate change in the future and can be seen as nature-based solutions (NBS) supporting climate change adaptation and mitigation strategies.

Resumen:Even though the Selenga is the main tributary to Lake Baikal in Russia, the largest part of the Selenga River basin is located in Mongolia. It covers a region that is highly diverse, ranging from almost virgin mountain zones to densely urbanized areas and mining zones. These contrasts have a strong impact on rivers and their ecosystems. Based on two sampling campaigns (summer 2014, spring 2015), we investigated the longitudinal water quality pattern along the Selenga and its tributaries in Mongolia. While headwater regions typically had a very good water quality status, wastewater from urban areas and impacts from mining were found to be main pollution sources in the tributaries. The highest nutrient concentrations in the catchment were found in Tuul River, and severely elevated concentrations of trace elements (As, Cd, Cu, Cr, Fe, Mn, Ni, Pb, Zn), nutrients (NH , NO , NO , PO ), and selected major ions (SO ) were found in main tributaries of Selenga River. Moreover, trace element concentrations during spring 2015 (a time when many mines had not yet started operation) were markedly lower than in summer 2014, indicating that the additional metal loads measured in summer 2014 were related to mining activities. Nevertheless, all taken water samples in 2014 and 2015 from the main channel of the Mongolian Selenga River complied with the Mongolian standard (MNS 1998) for the investigated parameters.

Resumen:During a study of psychrophilic hydrocarbon-degrading bacteria, two yellow, Gram-staining-negative, non-motile, and rod shaped bacteria, designated R-10-9T and K-4-2 were isolated from oil-contaminated soil from Ulaanbaatar, Mongolia. Both strains were able to grow at 0-32 °C, pH 5.0-9.5, and 0-1 % (w/v) NaCl concentration. These strains were taxonomically characterized by a polyphasic approach. On the basis of the results of 16S rRNA gene sequence analysis, R-10-9T and K-4-2 belong to the genus Flavobacterium and are closely related to Flavobacterium oncorhynchi 631-08T (97.80 and 98.09 % sequence similarity, respectively). The pairwise sequence similarity between R-10-9T and K-4-2 was observed to be 99.72 %. In both strains, the predominant respiratory quinone was menaquinone-6; the major polar lipid was phosphatidylethanolamine; and the major fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0, C16 : 0 3-OH, antesio-C15 : 0, C16 : 0, iso-C17 : 0 3-OH, and iso-C15 : 0 3-OH. The genomic DNA G+C contents of R-10-9T and K-4-2 were 35.9 and 35.4 mol%, respectively. The DNA-DNA relatedness between R-10-9T and K-4-2 was higher than 70 % but relatedness values with closely related reference strains were less than 35 %. The morphological, physiological, chemotaxonomic, and phylogenetic analyses clearly distinguished R-10-9T from its closest phylogenetic neighbours. Thus, R-10-9T represents a novel species of the genus Flavobacterium, for which the name Flavobacterium olei sp. nov. is proposed. The type strain is R-10-9T (=KEMB 9005-447T=KACC 18997T=JCM 31673T), and strain K-4-2 as an additional strain.
