BACKGROUND: In recent decades, there has been an epidemic growth of allergic diseases, in which fungi along with other allergens significantly play a role in their etiology. Spores of a number of micromycetes are present in the air. Aeropalynology environmental monitoring enables examination of the composition of airborne microorganisms, their dynamics, and role in the formation of allergic diseases. The Rostov region has climatic and geographical features that affect the qualitative and quantitative compositions of the fungal spectrum in the air environment. AIM: This study aimed to investigate the composition and features of the fungal spectrum of the air environment in Rostov-on-Don, to assess the dynamics of the concentration of fungal spores during the monitoring period (March to October), and to make a calendar of plant pollination and fungal spore production for this region. MATERIALS AND METHODS: In this longitudinal, observational, single-center study, aeroallergens were detected using a volumetric Burkard trap. Identification of plant pollen and fungal spores was performed by microscopy of colored slides obtained from a sticky tape covered with a special mixture. RESULTS: Results of aeropalynological monitoring in 2019 in the air environment of Rostov-on-Don revealed the presence of pollen taxa and fungal spores, represented by the mold fungi Cladosporium herbarum and Alternaria alternata in high increasing concentrations. Their dynamics were recorded throughout the observation period (March to October). The specific weight of fungal sensitization in patients with seasonal allergic rhinitis was 11.6%. CONCLUSIONS: This study identifies the regional features of the fungal spectrum of air allergens, and a calendar of dusting and sporulation was compiled for the city of Rostov-on-Don.

BACKGROUND: There is an increase in the proportion of patients suffering from allergic diseases caused by the plant pollen. Aeropalinologic monitoring of the air environment allows us to study the composition of aeroallergens and their role in the formation of pollen allergies. Features of the formation of aerial pollen spectra are closely related to the botanical-geographical and natural-climatic conditions of the region. The Rostov region has its own specific features, which is reflected in the qualitative and quantitative composition of pollen rain. AIM: To study the dynamics of pollination of allergenic plants in Rostov-on-Don, identify the prevailing taxa and create a calendar of pollination of plants for this region. MATERIALS AND METHODS: Aeroallergens were detected by using a volumetric Burkard trap. The identification of plant pollen and fungal spores was performed by microscopy of colored slides obtained from a sticky tape covered with a special mixture. RESULTS: In 2019, 21 taxa were registered in the air environment of Rostov-on-don (trees, meadows, haze, cereals, weeds), fungal spores were found in the air, represented by the mold fungi Cladosporium herbarum and Alternaria alternata in high growing concentrations. An increase in the vegetation period of pollination of trees (07.03.31.06), mares (02.0503.10), cereals (02.0414.09), weeds (18.0728.10) was detected According to the dynamics of pollen concentration, three periods of its growth were registered: spring-summer, summer and summer-autumn. The presence of birch pollen grains in a clinically significant concentration (36 pollen grain (PG)/m3) in this steppe region, an increase in the peak concentration of ragweed (393 PG/m3) in comparison with the same data for 1971 (265 PG/m3) was found. CONCLUSION: Regional features of the spectrum of air allergens were identified, and a dusting calendar was compiled for Rostov-on-Don.

Relevance. Characteristics of eruption of secondary teeth is of diagnostic and prognostic interest, is the basis for implementation of targeted therapeutic and preventive measures among children. No research has ever been carried out in Uzbekistan to study an age and gender regional features of secondary teeth eruption. The aim is to determine the timing and symmetry of secondary teeth eruption in children of the city of Tashkent of the Republic of Uzbekistan and comparative assessment with the children of different cities of Russia.Materials and methods. 3,834 children between 3 and 17 years were conducted dental examination. A comparative analysis was made of the initial, intermediate and final periods of eruption of secondary teeth for children of Uzbekistan (Tashkent city) and Russia (Saratov, Izhevsk and Sergach).Results. In Tashkent children of both gender, in most cases, lower teeth were erupted before than their antagonists. In girls, teeth were erupted earlier than their male counterparts. At the initial stage of eruption, asymmetry was more pronounced in boys than in girls, while in the middle and final stages it was more pronounced in the opposite direction. Observed asymmetry of antimere’s teeth were indicated left-handed permanent dentition in boys and right-handed in girls. Children of Tashkent city were observed permanent dentition in one group of teeth 1-16 months earlier, and in others – 1-24 months later than their peers in Russian cities. Revealed differences were more pronounced among boys than among girls. Children in Tashkent differed more from their peers in Sergach and less from those in Izhevsk. Conclusions. Regional peculiarities of permanent dentition in children of Tashkent city and revealed expressed differences with indicators of Russian children are the basis for development of separate age and  gender normative assessment permanent dentition tables for children of Uzbekistan.

This research was conducted to investigate the dynamics of airborne fungi using viable culture collection and in respect to different abiotic variables, including seasonal and intra-diurnal variations. A gravimetric method was used to sample airborne fungal deposition on potato dextrose agar plates on alternate days, for a year between April 2015 to March 2016. From 176 settle plate exposures, a total of 1197 mould and 283 yeast colony-forming units (CFU), 21 genera and 62 species were retrieved. The highest fungal spore count was recorded in February 2016, whereas the lowest count occurred in August 2015. The main constituents of the fungal airspora were attributed to Cladosporium (60.2%), Aspergillus (10.4%), Fusarium (9.4%), Alternaria (8.5%), and Ganoderma spp. (2.3%). Temperature was negatively correlated with total colony count (r = −0.231, p ≤ 0.05) or species richness (r = −0.267, p ≤ 0.001), while wind speed was positively correlated with total colony count (r = 0.484, p ≤ 0.001) or species richness (r = 0.257, p ≤ −0.001). The highest dispersal of fungal spores was obtained at 18:00, whereas the lowest fungal spores release was recorded at 00:00 (midnight). There were no significant differences in species composition and richness of the airborne fungal population between two study sites, the Industrial area and Qatar University Campus. The count of Alternaria spp. and Fusarium spp. were significantly higher at the Industrial area site, which corresponds to a higher CO2 level than the Qatar University site. This study lays the foundation for future work to assess the implications of such aeromycological data on public health.

Abstract. Primary biological aerosol particles (PBAP) are an abundant subset of atmospheric aerosol particles which comprise viruses, bacteria, fungal spores, pollen, and fragments such as plant and animal debris. The abundance and diversity of these particles remain poorly constrained, causing significant uncertainties for modelling scenarios and for understanding the potential implications of these particles in different environments. PBAP concentrations were studied at four different sites in the United Kingdom (Weybourne, Davidstow, Capel Dewi, and Chilbolton) using an ultra-violet light induced fluorescence (UV-LIF) instrument, the Wideband Integrated Bioaerosol Spectrometer (WIBS), versions 3 and 4. Using hierarchical agglomerative cluster (HAC) analysis, particles were statistically discriminated between. Fluorescent particles and clusters were then analysed by assessing their diurnal variation and their relationship to the meteorological variables, temperature and relative humidity, and wind speed and direction. Using local land cover types, sources of the suspected fluorescent particles and clusters were then identified. Most sites exhibited a wet discharged fungal spore dominance, with the exception of one site, Davidstow, which had higher concentrations of bacteria, suggested to result from the presence of a local dairy factory. Differences were identified as to the sources of wet discharged fungal spores, with particles originating from arable and horticultural land at Chilbolton, and improved grassland areas at Weybourne. Total fluorescent particles at Capel Dewi were inferred to comprise two sources, with bacteria originating from the broadleaf and coniferous woodland and wet discharged fungal spores from nearby improved grassland areas, similar to Weybourne. The use of HAC and a higher fluorescence threshold (9SD) produced clusters which were considered to be biological following the complete analysis. More knowledge of the reaction of speciated biological particles to differences in meteorology, such as relative humidity and temperature would aid characterisation studies such as this.

Urban water bodies are an important asset in terms of climate change. The accompanying vegetation is an integral part of the waterside space system and a source of ecosystem services and disservices. The composition of greenery in waterside spaces should therefore be preceded by detailed research. This research would be the basis for the development of recommendations for enhancement of the positive impact of vegetation on humans and minimisation of its negative effect. The aim of the study was to identify ecosystem services and disservices of vegetation in the four most important waterside recreation spaces in the city of Rzeszów, Poland, and to develop plant composition guidelines. A detailed inventory of vegetation and aerobiological monitoring of the presence of airborne allergenic pollen grains and fungal spores were carried out. Next, the ecosystem services and disservices of the vegetation were determined based on literature data and on our expert judgement. Additionally, a counting of the number of visitors to waterside areas was conducted. All these steps were used to develop recommendations for shaping the vegetation of study areas. The results of the investigations show that the boulevards along the artificial lake function completely differently than other investigated places as the area resembles an urban park, and the water is not the main attraction in this space. The vegetation of the boulevards and the nearby gravel-pit bathing area has mostly a spontaneous character and offers the widest range of ecosystem services and disservices. The management of the vegetation should focus on its health-enhancing values. The vegetation growing near the outdoor swimming pools has been designed by man. Nevertheless, it requires recomposing and is targeted specifically at the enhancement of the visual attractiveness. Additionally, there is a need for planting compact deciduous trees that will provide shade at the multi-media fountain.

In the work there was performed an analysis of the indices of recorded incidence of rotavirus infection (RVI) in the territory of 40 subjects of the Russian Federation for the period 2008-2012. For the identification of the monthly peak of the incidence there was evaluated the temporal distribution of the relative indices of the RVI incidence within each subject of the observation. There was revealed the independent beginning of the winter-spring seasonal rise of the RVI incidence in three groups of territories of the Russian Federation (1 - Kirov, Kostroma, Nizhny Novgorod region; 2- Republic of Khakassia, Kemerovo region; 3 - Amur region). In the territory of the South and the North Caucasus Federal District (Krasnodarsky and Stavropolsky Krai, Rostov region) there was noted the second, summer-autumn seasonal rise in the RVI incidence. The obtained data provide an overview of the seasonal-geographical distribution of the RVI incidence in the territory of Russia in conditions of the absence of the use of rotavirus vaccines

The local budgets are an instrument of financial-economic regulation of the development of regions and the State as a whole. Both the efficient formation and administration of local budgets should be based on a combination of financial-economic relationships in the area of revenue generation, implementation of budget expenditures, the inter-budgetary relations and the development together with implementation of the balanced socio-economic policies directed towards ensuring the socio-economic growth of regions. The reform of budget decentralization has provided local governments with broader rights and new sources of financial resources, which has collectively increased the financial viability and autonomy of the regions. In this article article considers the peculiarities of the formation and implementation of local budgets (on the example of the budget of the city of Irpin). The sources of formation are described city budget revenues and directions of their use. In a section of revenue breakdown components of tax revenues on the main taxes and non-tax receipts of the local budget are analyzed. Specific weight of the intergovernmental transfers in the course of formation of income of local budgets is investigated. Analyses directions of use of budgetary resources by local governments. The main problems existing when forming revenues of local budgets are defined. Having analyzed the structure and dynamics of revenues and expenditures of the local budget. The revenues of the local budget of the city of Irpin have shown a growing dynamics, and expenditures tend to increase. The analysis shows that there are tendencies to increase their volume, which is certainly a positive aspect of the activities of local governments and decentralization reform. However, transfers make up an important part of the budget, which is negative, as the city budget is not fully independent. Of course, it is impossible to achieve full financial independence of the region in modern conditions, but it would be expedient to direct the vector of development to achieve financial independence. Analysis of the structure of expenditures by functional classification shows that during 2016-2019 most of the expenditures of local budgets were directed to the socio-cultural sphere. According to the analysis, the city of Irpin has a strong enough financial base to meet the needs of its residents. In addition, the analysis of the use of the city budget shows the diversity of expenditures and the presence of positive experience of community development.

The aim of work was the objective coverage of the 1930s events, associated with the opening of Medical Institute in Voroshilov (Stavropol), revealing the background of its creation, analysis of the problems accompanying decision implementation. Using the comparative analysis method in the archival sources study common trends and patterns of regional development and their cause and effect relationships, which contributed to pauses in the university organization, were identified. The main prerequisites for the institute creation were general tendency to increase the medical schools number in the country to provide the population with medical staff of expanding network of health care institutions; regional features, reflected in the fact that the Stavropol was one of the major administrative, cultural and scientific centers in the region, which had a favorable equidistant position from the cities with already existing medical schools. In addition to that, Voroshilov Medical Institute was not established on the basis of the department or by already established institution transfer to the city, as it has been originally planned by the RSFSR Council of People’s Commissars. Although the decision to open a medical school in Stavropol has been made, the city did not have the necessary areas for its placement. Local authorities petitions on medical school establishment were of adventurous nature, the measures they took were not implemented in time. The university organization proceeded in difficult conditions: academic buildings, dormitories for students and teachers were lacking; premises surrender to medical institute from other organizations was delayed for objective reasons. Thanks to the university administration persistent efforts, with the higher authorities support Medical Institute was opened and began its work. We can not say that with the opening of the Institute the stage of its organization was completed as abovementioned problems had to be solved in the future. Otherwise, liquidation threatened to the university.
