Hospital admissions of children under 5 years of age with diarrhea are primarily associated with group A rotavirus （RVA） infection. In this retrospective study, the population structure of viruses linked to AGE etiology in young children hospitalized with AGE in Moscow was evaluated, and molecular characterization of RYA strains was performed. Fecal specimens were collected from children under 5 years old hospitalized with AGE between 2009 and 2014 in Moscow, Russia. Multiplex real-time reverse transcription PCR was used to detect enteric viruses and for G/[P]-genotyping of isolated RVAs. Sequencing of RVA VP7 and VP4 cDNA fragments was used to validate the data obtained by PCR- genotyping. The main causes for hospitalization of children with AGE were RVA （40.1%）, followed by noroviruses （11.4%）, while adenoviruses, astroviruses, sapoviruses, enteroviruses, and orthoreoviruses were detected in 4.7%, 1.9%, 1.4%, 1.2%, and 0.2% of samples tested, respectively. Nosocomial infections, predominantly associated with RVAs and noroviruses, were detected in 24.8% of cases and occurred significantly more frequently in younger infants. The predominant RVA genotype was G4P[8], detected in 38.7% of RVA-positive cases, whereas genotypes G1P[8], G9P[8], G3P[8], and G2P[4] were found in 11.8%, 6.6%, 4.2%, and 3.3% of cases, respectively. Together, the presence of circulating RVA strains with rare VP7 and VP4 gene variants （G6 and P[9]） highlights the need to conduct continuous epidemiological monitoring of RVA infection.展开更多

To characterize the habitat conditions of microbiota in the soils of different functional zones of the city, the acid-base conditions and the contents of exchangeable and water-soluble nitrogen, mobile heavy metals, and soluble salts were determined. The diversity of species of algal-cyanobacterial communities, the composition of the dominant species, the proportions of different ecological groups of diatom algae, the diversity of soil nano- and microfauna, and the abundance of colorless and colored mycelium in the urban soils were characterized. The analysis of these parameters showed that the degree of technogenic impact on soil microbiota decreases in the following sequence of functional zones of the city: industrial > traffic > residential > recreation.展开更多

Moscow City and Moscow Region （Moscow Oblast） are the parts of the Moscow Capital Region. According to the Constitution of Russia, adopted in December 1993, Moscow Region and Moscow City are two independent federal subjects of Russian Federation. The sustainable development of Moscow City and Moscow Region as an integrated regional economic and natural complex which plays the most important part in Russia＇s economy must be based on the integrated solution to the problems of environmental protection, social equity, and economic feasibility. The latest initiative of Russian Government concerns the creation of the Greater Moscow within the new borders of Moscow. Making the decision on the extension of the city limits and stimulation of the Moscow Agglomeration development provides the real way of resolution of the accumulated problems and provides enormous impetus to the sustainable development. The key task of the environmentally sound development of the Greater Moscow is to relieve the historical center of Moscow City; maintain the rational balance of built-up areas, natural and rural landscapes; ensure joint control of the urban development and economic activity; and create the favorable environment for the population.展开更多

Mercury concentrations in venous and umbilical cord blood, urine, hair, and nails were determined by means of instrumental neutron activation analysis and cold vapor atomic absorption spectrometry. Peculiarities of selection, transportation, storage, and preparation for analysis of samples of hair, nails, urine and umbilical venous blood are described. The determined concentrations of mercury in the studied diagnostic biomaterials are compared with normal and thresholds values. Although increased mercury concentrations were observed in some cases, no significant exposure of mercury was evident in general in the study towns. A positive correlation between the degree of consumption of seafood during pregnancy and a high content of mercury in the analyzed diagnostic biomaterials was shown.展开更多

Neotectonic structures of different ranks--elevations and depressions, lineaments and GDAZ （geodynamic active zones） are presented on the map. Geodynamic active zones are linear or isometric crust volumes of different scales that localized spatially, where conditions for tectonic stress concentration and relaxation, and high gradients of movements and rocks deformity are favorable by different reasons. They differ from active faults, which are rare on geodynamic-stable platform territories, by absence of noticeable displacements in rocks and a more geodynamic stability. Nevertheless, GDAZ can be hazard to engineering buildings, since these zones are favorable for developing exogenous （such as erosion, impoundment, karst, sliding, etc.） and endogenous geological processes （such as seismicity, water-fluid permeability and heat flux）. They can also become migration and localization channels of nature-anthropogenic pollution.展开更多

There are several factors on which blood concentration of 25 （OH） D--calcidiol-depends. However, it is evident that among numerous factors we should orient on several most significant and develop correction scheme for the deficient condition in every region. Aim： to assess vitamin D levels in adolescents residing in Moscow, to correct their calcidiol status based on a baseline blood concentration of the transport metabolite. Materials and methods： 769 adolescents aged 11-18 years were examined and their blood concentration of 25 （OH） D was determined. Then, 218 patients were randomized to 2 groups： the treatment group received food supplement ＂Minisun~ Vitamin D3＂ in tablets, the control group received placebo. Cholecalciferol dosage was prescribed depending on the baseline calcidiol level in patients. The study continued for 6 months, after that blood was re-withdrawn for calcidiol level. Results： low calcidiol provision was observed among school children： median 25 （OH） D was 16.3 [11.4-20.8] ng/mL, only 5.2% of patients had normal blood concentration of calcidiol. There-examination showed significant differences in vitamin D status in the treatment and control group, in the meantime, during cholecalciferol supplementation, median 25 （OH） D in patients of the treatment group was increased from 16.2 [ 12.25-19.3] ng/mL to 24.2 [21.05-26.4] ng/mL （p 〈 0.001）. Conclusions： the larger part of child population--70.6% has 25 （OH） D concentration 〈 20 ng/mL, cholecalciferol doses used in the study allow eliminating calcidiol deficiency and overcome the boundary of 20 ng/mL, but for normalization of vitamin D status in blood of adolescents residing in Moscow higher dosages shall be used which is to be confirmed by further studies.展开更多
