    In this work, we demonstrate new data that allows us to accurate geochronological ranges of formation of the Kresty alkaline-ultrabasic massif, which is considered to be a satellite of the Gulinian giant pluton. We also interpreted geological, geochemical and isotope-geochemical data obtained earlier for major varieties of this volcanic-plutonic association taking into account new geochronological results, as well as considered new aspects/information on matter source of alkaline-ultrabasic massifs from this province. One of the main aspects is interaction of Siberian super plume matter with hosting substrate of Siberian craton continental crust

    Aim: To study the epidemiological patterns of invasiveΒ meningococcal disease in Novosibirsk region within a timeΒ period from 1992 to 2015.Methods: retrospective comparative epidemiologicalΒ analysis.Results: During the analyzed period the annual incidenceΒ rate of invasive meningococcal disease was higher than averageΒ annual incidence rate in Russian Federation. Totally1690Β cases were registered, average incidence rate for the periodΒ 2000–2015 was 2,2/100,000 exceeding the neighbor regions.Β The incidence had a tendency to continually decline and isΒ characterized by the cyclical fluctuations with period of 4-7Β years. Majority of cases occurred in children < 14 years,Β varying from 77,3% in 2001 to 57,8% in 2008. The highestΒ incidence was registered in children <12 month reachingΒ 124/100,000 of population in 2003. The increase of mortalityΒ correlated with the decrease of incidence, average mortalityΒ for period 1992–2015 was 11,4%. In etiologic structureΒ serogroup B is predominant – 40,9%, serogrup A – 20,6%,Β serogrup C – 14,7%. The distinctiveness of epidemiology isΒ cyclic dynamics with the periods of predominance of serogroupΒ A (up to 48% in 2014). In serum analysis performedΒ 2012 45% of probes were positive for serogroup A what demonstratesΒ circulation of this serogoup among population.Conclusion: High incidence among children <14 yearsΒ and especially among children <12 month in emerging riskΒ of the forthcoming rise in incidence of meningococcal diseaseΒ and insufficient surveillance provide need in activationΒ of tactics of specific immuneprophylactics. ЦСль: ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΈΠ΅ эпидСмиологичСских закономСрностСй Π³Π΅Π½Π΅Ρ€Π°Π»ΠΈΠ·ΠΎΠ²Π°Π½Π½ΠΎΠΉ ΠΌΠ΅Π½ΠΈΠ½Π³ΠΎΠΊΠΎΠΊΠΊΠΎΠ²ΠΎΠΉ ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΈ в Новосибирской области Π·Π° 1992–2015 Π³Π³.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹: рСтроспСктивный ΡΡ€Π°Π²Π½ΠΈΡ‚Π΅Π»ΡŒΠ½Ρ‹ΠΉ эпидСмиологичСский Π°Π½Π°Π»ΠΈΠ·.Π Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹: Π·Π° Π°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΡƒΠ΅ΠΌΡ‹ΠΉ ΠΏΠ΅Ρ€ΠΈΠΎΠ΄ показатСли заболСваСмости Π“Π€ΠœΠ˜ ΡΡ‚Π°Π±ΠΈΠ»ΡŒΠ½ΠΎ ΠΏΡ€Π΅Π²Ρ‹ΡˆΠ°Π»ΠΈ ΠΏΠΎΠΊΠ°Π·Π°Ρ‚Π΅Π»ΠΈ ΠΏΠΎ Российской Π€Π΅Π΄Π΅Ρ€Π°Ρ†ΠΈΠΈ.

    The article presents an analysis of the results of a questionnaire survey of existing doctors of medical institutions in the city of Yekaterinburg and the Sverdlovsk region on vaccination. The level of knowledge of the main documents related to vaccination was analyzed at the subjective and objective levels. It was revealed that the subjective assessment of their own knowledge among a significant part of the respondents does not coincide with the real ideas about vaccination. The similarities and differences in the self-assessment of knowledge and attitudes towards vaccination of doctors of various ages and specialties are considered.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ прСдставлСн Π°Π½Π°Π»ΠΈΠ· Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚ΠΎΠ² анкСтирования Π΄Π΅ΠΉΡΡ‚Π²ΡƒΡŽΡ‰ΠΈΡ… Π²Ρ€Π°Ρ‡Π΅ΠΉ Π»Π΅Ρ‡Π΅Π±Π½ΠΎ-профилактичСских ΡƒΡ‡Ρ€Π΅ΠΆΠ΄Π΅Π½ΠΈΠΉ Π³ΠΎΡ€ΠΎΠ΄Π° Π•ΠΊΠ°Ρ‚Π΅Ρ€ΠΈΠ½Π±ΡƒΡ€Π³ ΠΈ БвСрдловской области ΠΎ Π²Π°ΠΊΡ†ΠΈΠ½ΠΎΠΏΡ€ΠΎΡ„ΠΈΠ»Π°ΠΊΡ‚ΠΈΠΊΠ΅.

    The article presents the results of a comparative clinical and laboratory analysis of noravirus and rotavirus gastroenteritis. The relationship between the degree of dehydration identified by clinical signs and its laboratory manifestations is analyzed. It has been established that clinical and laboratory signs of dehydration are more severe in patients with rotavirus infection, however, the possibility of acute renal failure due to dehydration is higher in patients with noravirus gastroenteritis.Π’ ΡΡ‚Π°Ρ‚ΡŒΠ΅ прСдставлСны Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ ΡΡ€Π°Π²Π½ΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΠ³ΠΎ ΠΊΠ»ΠΈΠ½ΠΈΠΊΠΎ-Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½ΠΎΠ³ΠΎ Π°Π½Π°Π»ΠΈΠ·Π° норовирусного ΠΈ ротавирусного гастроэнтСрита.ΠŸΡ€ΠΎΠ°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Π½Π° связь ΠΌΠ΅ΠΆΠ΄Ρƒ ΡΡ‚Π΅ΠΏΠ΅Π½ΡŒΡŽ Π΄Π΅Π³ΠΈΠ΄Ρ€Π°Ρ‚Π°Ρ†ΠΈΠΈ, выявлСнной ΠΏΠΎ клиничСским ΠΏΡ€ΠΈΠ·Π½Π°ΠΊΠ°ΠΌ, ΠΈ Π΅Ρ‘ Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹ΠΌΠΈ проявлСниями.

    The purpose of the study is to determine the effectiveness of the specialized product Fit Tonus for correcting the psychophysiological state and neuromuscular transmission in highly qualified athletes.Materials and methods: the objects of research were: specialized product of sports nutrition for correcting the psychophysiological state and neuromuscular transmission Fit Tonus; 21 male martial arts athletes aged 14 to 25 years. The researches were carried out in accordance with official and conventional techniques. Body temperature, breathing rate, blood pressure level, heart rate was determined, heart rate variability, ECG, external breathing, O2 intake, total urine test, clinical blood test, biochemical blood indices were evaluated, water sectors of the body, body skinny weight, body fat weight were determined. Full-function cardiopulmonary analysis was performed using the Meta Lyzer 3B inpatient cardio-respiratory loading diagnostic system (Cortex Medical, Germany). Maximum oxygen consumption was determined by a Cosomed metabolograph (Italy). Biochemical parameters (bilirubin, ACT, ALT, urea, uric acid, glucose, cholesterol, HGT, amylase, alkaline phosphatase, creatinine) were examined on a Humalyzer biochemical analyzer. Water sectors of the body, the value of skinny body weight and fat body weight were determined on an analyzer for assessing the balance of water sectors of the body (Medass, Russia).Results: in the analysis of biochemical blood values, the blood levels of indicator enzymes and their isoforms were normalized in a short time, despite high training loads. This fact reflects the adaptation of the athlete’s body to high-intensity physical activity when taking the Fit Tone product. The obtained results of the increase in GUS, FFV and Tiffno test indicate an increase in both functional capabilities and functional abilities of the external breathing system, as well as an increase in the efficiency of the respiratory center in athletes who received the tested product. The effectiveness of the test product is confirmed by the results of dynamic and stress samples in a stabilometric study. Results of examination of psychophysical status of single wrestlers showed that during usage of developed product such indicators as performance, vegetative coefficient, dynamism, speed of movement, accuracy of actions, stability of actions are significantly increased. At the same time, the level of fatigue and anxiety is reliably reduced.Conclusions: the results of the researches performed showed that the product developed demonstrated efficacy for most of the parameters under research in the main group compared to the control (placebo)

    Characterization of the complete genome sequence of the recombinant norovirus GII.P16/GII.4_Sydney_2012 revealed in Russia

    Get PDF
    Noroviruses (the Caliciviridae family) are a common cause of acute gastroenteritis in all age groups. These small non-envelope viruses with a single-stranded (+)RNA genome are characterized by high genetic variability. Continuous changes in the genetic diversity of co-circulating noroviruses and the emergence of new recombinant variants are observed worldwide. Recently, new recombinant noroviruses with a novel GII.P16 polymerase associated with different capsid proteins VP1 were reported. As a part of the surveillance study of sporadic cases of acute gastroenteritis in Novosibirsk, a total of 46 clinical samples from children with diarrhea were screened in 2016. Norovirus was detected in six samples from hospitalized children by RT-PCR. The identified noroviruses were classified as recombinant variants GII.P21/GII.3, GII.Pe/GII.4_Sydney_2012, and GII.P16/GII.4_Sydney_2012 by sequencing of the ORF1/ORF2 junction. In Novosibirsk, the first appearance of the new recombinant genotype GII.P16/GII.4_Sydney_2012 was recorded in spring 2016. Before this study, only four complete genome sequences of the Russian GII.P16/GII.3 norovirus strains were available in the GenBank database. In this work, the complete genome sequence of the Russian strain Hu/GII.P16-GII.4/RUS/Novosibirsk/NS16-C38/2016 (GenBank KY210980) was determined. A comparison of the nucleotide and the deduced amino acid sequences showed a high homology of the Russian strain with GII.P16/GII.4_Sydney_2012 strains from other parts of the world. A comparative analysis showed that several unique substitutions occurred in the GII.P16 polymerase, N-terminal p48 protein, and minor capsid protein VP2 genes, while no unique changes in the capsid VP1 gene were observed. A functional significance of these changes suggests that a wide distribution of the strains with the novel GII.P16 polymerase may be associated both with several amino acid substitutions in the polymerase active center and with the insertion of glutamic acid or glycine in an N-terminal p48 protein that blocks the secretory immunity of intestinal epithelial cells. Further monitoring of genotypes will allow determining the distribution of norovirus recombinants with the polymerase GII.P16 in Russia
