A comparison of the characteristics of extreme drought during the late 20 th and early 21st centuries over Eurasia and North America

The atmospheric general circulation character during summer droughts over Eastern Europe / Western Russia and North America from 1970-2020 is examined here. A criterion to examine atmospheric drought events encompassed the summer season was used to determine which years were driest using precipitation, evaporation, and areal coverage. The relationship between drought and atmospheric character using the Dzerzeevsky climatic classification scheme, atmospheric blocking, teleconnections, and information entropy are used to study the atmospheric dynamic

Linear and nonlinear optical properties of trigonal borate crystals K7MIn2-xYbx(B5O10)3 (M = Ca, Sr, Ba; x=0…2) with isolated B5O10 units

Noncentrosymmetric borates K7MIn2−xYbx(B5O10)3 (M = Ca, Sr, Ba; x = 0…2) were synthesized by the solid state reaction and the crystals were successfully grown by the top seeded solution growth method using the K2O-B2O3-MF2 flux. According to Rietveld refinement, the crystal structure belongs to the noncentrosymmetric R32 space group. Also, the octahedrally coordinated In atoms are located at wide ranges ∼8 Å which may be promising for phosphor and laser applications. Samples with ytterbium show a characteristic emission band in the range of 950–1050 nm related to the 2F5/2 → 2F7/2 transition of Yb3+ ions that is commonly used for laser generation. IR, Raman and absorption spectra were obtained for the samples as well. The short cut edge of UV absorption, SHG intensity comparable with KDP and low concentration quenching of luminescence suggest that the K7MIn2−xYbx(B5O10)3 borates are promising self-frequency doubling materials

Molecular Genetic Analysis of the Complete Genome of Tick-Borne Encephalitis Virus (Siberia Subtype): Modern Kolarovo-2008 Isolate

Determined is the complete genome sequence of Kolarovo-2008 strain (Siberia subtype) of Tick-borne encephalitis virus (TBEV), isolated from a tick in the suburbs of the Tomsk city. Nucleotide sequence analysis testifies of the fact that the level of genetic differences within the Siberian subtype of TBEV amounts to 10 % of the nucleotide sequence and to 7 % of amino-acid sequence for certain virus genes. 3'-HTO of the genome of Siberian subtype has the highest rate of variability and the homology level ranging from 65 to 97 %. Kolarovo-2008 and Vasilchenko (isolated in Novosibirsk in 1969) strains have the highest level of genome homology. The level of dissimilarity between the two Tomsk strains is substantially higher: the total number of amino-acid substitutions in Tomsk Zausaev and Kolarovo-2008 strains equals to 124, and 3'HTO level of homology is 79 %. Identified genetic variability of the Siberian subtype of TBEV is of a great importance for further development and enhancement of tick-borne encephalitis virus diagnostics

Detection of tick-borne pathogens in wild birds and their ticks in Western Siberia and high level of their mismatch

Abstract: The Tomsk region located in the south of Western Siberia is one of the most high-risk areas for tick-borne diseases due to elevated incidence of tick-borne encephalitis and Lyme disease in humans. Wild birds may be considered as one of the reservoirs for tick-borne pathogens and hosts for infected ticks. A high mobility of wild birds leads to unpredictable possibilities for the dissemination of tick-borne pathogens into new geographical regions. The primary goal of this study was to evaluate the prevalence of tick-borne pathogens in wild birds and ticks that feed on them as well as to determine the role of different species of birds in maintaining the tickborne infectious foci. We analysed the samples of 443 wild birds (60 species) and 378 ticks belonging to the genus Ixodes Latraille, 1795 collected from the wild birds, for detecting occurrence of eight tick-borne pathogens, the namely tick-borne encephalitis virus (TBEV), West Nile virus (WNV), and species of Borrelia, Rickettsia, Ehrlichia, Anaplasma, Bartonella and Babesia Starcovici, 1893, using RT-PCR/or PCR and enzyme immunoassay. One or more tick-borne infection markers were detected in 43 species of birds. All markers were detected in samples collected from fieldfare Turdus pilaris Linnaeus, Blyth’s reed warbler Acrocephalus dumetorum Blyth, common redstart Phoenicurus phoenicurus (Linnaeus), and common chaffinch Fringilla coelebs Linnaeus. Although all pathogens have been identified in birds and ticks, we found that in the majority of cases (75.5%), there were mismatches of pathogens in birds and ticks collected from them. Wild birds and their ticks may play an extremely important role in the dissemination of tick-borne pathogens into different geographical regions

Evaluation of the effectiveness of post-destructive rehabilitation in patients with HPV-associated cervical disease

The evaluating of the results of rehabilitation measures after destructive treatment in patients with cervical leukoplakia associated with papillomavirus infection has been analyzed. It has been established that the use of the antibacterial drug Elzhina at the stage of rehabilitation is necessary to prevent secondary bacterial infection and improve regenerative processes, and the use of the vaginal gel Biofam, which includes lactic acid, glycogen and thyme oil, provides a combined advantage in colonization of the vagina with a lactobacilli flora and restores the pH level, which prevents the further reproduction of opportunistic pathogenic microflora and contributes to a reliable the timing of epithelization, the reduction in the number of relapses.Проведен анализ результатов реабилитационных мероприятий после деструктивного лечения пациенток с лейкоплакией шейки матки, ассоциированной с папилломавирусной инфекцией. Установлено, что применение антибактериального препарата Эльжина на этапе реабилитации необходимо для предупреждения вторичного бактериального инфицирования и улучшения регенераторных процессов, а использование вагинального геля Биофам, в состав которого входит молочная кислота, гликоген и тимьяновое масло, обеспечивает комбинированные преимущества в колонизации влагалища лактобациллярной флорой и восстанавливает уровень pH что препятствует дальнейшему размножению условно-патогенной микрофлоры и способствует достоверному сокращению сроков зпителизации, уменьшению количества рецидивов

Synthesis and growth of rare earth borates NaSrR(BO3)2 (R = Ho− Lu, Y, Sc)

NaSrR(BO3)2(R = Ho-Lu, Y, Sc) compounds were obtained for the first time. Their structures exhibit disordered positions of Sr2+and Na+ atoms while RO6polyhedra are connected through the BO3 groups. Large distances between R atoms and high transparency in the range of 250-900 nm make them promising for phosphor applications. A pathway to obtain single crystals was shown by growing NaSrY(BO3)2and NaSrYb-(BO3)2by the top seeded solution growth method with Na2O-B2O3-NaFflux

A 300-year record of sedimentation in a small tilled catena in Hungary based on δ13C, δ15N, and C/N distribution

Purpose Soil erosion is one of the most serious hazards that endanger sustainable food production. Moreover, it has marked effects on soil organic carbon (SOC) with direct links to global warming. At the same time, soil organic matter (SOM) changes in composition and space could influence these processes. The aim of this study was to predict soil erosion and sedimentation volume and dynamics on a typical hilly cropland area of Hungary due to forest clearance in the early eighteenth century. Materials and methods Horizontal soil samples were taken along two parallel intensively cultivated complex convex-concave slopes from the eroded upper parts at mid-slope positions and from sedimentation in toe-slopes. Samples were measured for SOC, total nitrogen (TN) content, and SOMcompounds (δ13C, δ15N, and photometric indexes). They were compared to the horizons of an in situ non-eroded profile under continuous forest. On the depositional profile cores, soil depth prior to sedimentation was calculated by the determination of sediment thickness. Results and discussion Peaks of SOC in the sedimentation profiles indicated thicker initial profiles, while peaks in C/N ratio and δ13C distribution showed the original surface to be ~ 20 cm lower. Peaks of SOC were presumed to be the results of deposition of SOC-enriched soil from the upper slope transported by selective erosion of finer particles (silts and clays). Therefore, changes in δ13C values due to tillage and delivery would fingerprint the original surface much better under the sedimentation scenario than SOC content. Distribution of δ13C also suggests that the main sedimentation phase occurred immediately after forest clearance and before the start of intense cultivation with maize. Conclusions This highlights the role of relief in sheet erosion intensity compared to intensive cultivation. Patterns of δ13C indicate the original soil surface, even in profiles deposited as sediment centuries ago. The δ13C and C/N decrease in buried in situ profiles had the same tendency as recent forest soil, indicating constant SOM quality distribution after burial. Accordingly, microbiological activity, root uptake, and metabolism have not been effective enough to modify initial soil properties
