    Objective – assessment of effectiveness of the measures for biological safety provision at potentially hazardous facilities in the territory of the Republic of Tatarstan in the process of preparation and holding of FIFA World Cup-2018 in Kazan. Materials and methods. Regulatory-legal acts covering the requirements to the provision of biological safety during the work with pathogenic biological agents, international guidelines and documents determining inter-agency collaboration between the Rospotrebnadzor Administration in the Republic of Tatarstan and other departments and inter-agency task forces (Office of the Federal Security Bureau of Russia in the Republic of Tatarstan, Counter-Terrorism Commission in the Republic of Tatarstan, etc) were studied. Results and discussion. Considered were managerial-methodological approaches and matters of inter-agency cooperation on biological safety provision during preparation and holding of FIFA World Cup-2018 in Kazan. Biological safety was examined through the prism of its provision while working with pathogenic biological agents at potentially hazardous biological facilities and  counterterrorism integrity of the objects. The guiding, directive document in the performance of the complex of measures on biological safety provision and inter-agency collaboration was the Order of the President of the Russian Federation dated May 09, 2017 No 202 “On peculiarities of application of reinforced security measures during holding of FIFA World Cup-2018 and FIFA Confederations Cup-2017 in Russia”. As the result of the measures conducted, biological safety, including counter-terrorism security of potentially hazardous biological objects and sanitary-epidemiological welfare, was fully provided

    The ongoing COVID-19 pandemic represents an unprecedented global health crisis. Here, we report the identification of a synthetic nanobody (sybody) pair (Sb#15 and Sb#68) that can bind simultaneously to the SARS-CoV-2 spike-RBD and efficiently neutralize pseudotyped and live-viruses by interfering with ACE2 interaction. Two spatially-discrete epitopes identified by cryo-EM translated into the rational design of bispecific and tri-bispecific fusions constructs, exhibiting up to 100- and 1000-fold increase in neutralization potency. Cryo-EM of the sybody-spike complex further revealed a novel up-out RBD conformation. While resistant viruses emerged rapidly in the presence of single binders, no escape variants were observed in presence of the bispecific sybody. The multivalent bispecific constructs further increased the neutralization potency against globally-circulating SARS-CoV-2 variants of concern. Our study illustrates the power of multivalency and biparatopic nanobody fusions for the development of clinically relevant therapeutic strategies that mitigate the emergence of new SARS-CoV-2 escape mutants

    Introduction. In recent years, much attention has been paid to the study of extracellular microparticles (microvesicles and exosomes) and their role in the pathogenesis of human diseases.The objective of this study was to determine the number and size of plasma extracellular microparticles (PEMP) in patients with severe and extremely severe COVID-19 and correlate these data with the markers of hemostasis activation, inflammation, and tissue damage.Methods and Materials. The study included 29 patients with severe and extremely severe COVID-19. Concentration and size of PEMP were determined by nanoparticle trajectory analysis (NTA). All patients underwent the complete blood count and the thromboelastometry (TEM). Hemostatic, biochemical, and immunological parameters were assessed including fibrinogen, prothrombin time, activated partial thromboplastin time, D-dimer, C-reactive protein, lactate dehydrogenase, procalcitonin, von Willebrand factor antigen, interleukin 6, and interleukin 18.Results. There were 14 patients (48.3 %) discharged from the ICU with improvement (group 1— survived patients), and 15 patients (51.7 %) with lethal outcomes (group 2 — lethal outcome); the PEMP concentration did not differ between these groups. In group 2, there were heterogeneity of PEMP population, and a tendency to the larger PEMP size (p=0.074). In all patients, the PEMP concentration correlated negatively with both prothrombin time and the number of large platelets; the size of PEMP correlated negatively with the level of von Willebrand factor antigen, and positively with the fibrinogen. In group 1, the PEMP concentration had a direct correlation with both the level of interleukin 18 and maximum clot lysis in TEM; the PEMP size had a direct correlation with the maximum clot lysis in TEM and an inverse correlation with both the level of procalcitonin and maximum clot density in TEM.Conclusion. Our study confirms the importance of the process of extracellular microparticles formation in the COVID-19 pathogenesis. Our findings are consistent with the hypothesis that the parameters of PEMP population can be predictive biomarkers of the COVID-19 severity.Введение. В последние годы большое внимание уделяется изучению внеклеточных микрочастиц — микровезикул и экзосом — и их роли в патогенезе заболеваний человека.Цель — проанализировать количество и размеры внеклеточных микрочастиц плазмы крови (ВМЧПК) у пациентов с COVID-19 тяжелого и крайне тяжелого течения и сопоставить эти параметры с лабораторными маркерами активации гемостаза, воспаления и повреждения тканей.Методы и материалы. В исследование были включены 29 пациентов с COVID-19 тяжелого и крайне тяжелого течения. Концентрацию и размеры ВМЧПК определяли методом анализа траекторий наночастиц (nanoparticle trajectory analysis, NTA). Пациентам выполняли общий клинический анализ крови и тромбоэластометрию (ТЭМ), а также оценивали в крови коагулологические, биохимические и иммунологические показатели, включая фибриноген, протромбиновое время, активированное частичное тромбопластиновое время, D-димер, С-реактивный белок, лактатдегидрогеназу, прокальцитонин, антиген фактора Виллебранда, интерлейкины-6 и -18.Результаты. Были выписаны из отделения реанимации и интенсивной терапии с улучшением 14 (48,3 %) пациентов (группа 1 — выжившие), а 15 (51,7 %) пациентов умерли (группа 2 — летальный исход); концентрация ВМЧПК между этими группами не различалась. В группе 2 была выявлена гетерогенность размера ВМЧПК, а также тенденция к увеличению размера ВМЧПК (р=0,074). Среди всех обследованных пациентов концентрация ВМЧПК обратно коррелировала с протромбиновым временем и числом крупных тромбоцитов, а размер ВМЧПК обратно коррелировал с уровнем антигена фактора Виллебранда и имел прямую корреляцию с фибриногеном. В группе 1 концентрация ВМЧПК имела прямую корреляцию с интерлейкином-18 и максимальным лизисом тромба при ТЭМ, а размер ВМЧПК прямо коррелировал с максимальным лизисом тромба при ТЭМ и обратно коррелировал с прокальцитонином и максимальной плотностью сгустка при ТЭМ.Заключение. Проведенное исследование подтверждает важность процесса образования внеклеточных микрочастиц в патогенезе новой коронавирусной инфекции (COVID-19) и согласуется с гипотезой о том, что параметры пула ВМЧПК могут являться прогностическими биомаркерами степени тяжести COVID-19

    AI is a viable alternative to high throughput screening: a 318-target study

    : High throughput screening (HTS) is routinely used to identify bioactive small molecules. This requires physical compounds, which limits coverage of accessible chemical space. Computational approaches combined with vast on-demand chemical libraries can access far greater chemical space, provided that the predictive accuracy is sufficient to identify useful molecules. Through the largest and most diverse virtual HTS campaign reported to date, comprising 318 individual projects, we demonstrate that our AtomNet® convolutional neural network successfully finds novel hits across every major therapeutic area and protein class. We address historical limitations of computational screening by demonstrating success for target proteins without known binders, high-quality X-ray crystal structures, or manual cherry-picking of compounds. We show that the molecules selected by the AtomNet® model are novel drug-like scaffolds rather than minor modifications to known bioactive compounds. Our empirical results suggest that computational methods can substantially replace HTS as the first step of small-molecule drug discovery

    © 2020 Siberian State Medical University. All rights reserved. The aim. To evaluate the association of fibrinogen (FGB), tumor necrosis factor α (TNFα), interleukin 1β (IL-1β), lipoprotein lipase (LPL), platelet glycoprotein (ITGB3), and transforming growth factor β (TGFB1) genes with the incidence of recurrent myocardial infarction (MI) in patients living in the middle Volga region. Materials and methods. The study included 104 people with recurrent MI compared to 280 people who had just one episode of MI. TNFα (rs1800629), IL1B (rs16944), TGFB1b (rs1800469), FGB (rs1800788), ITGB3 (rs5918) and LPL (rs328) gene polymorphism was determined in all patients using competing TaqMan probes. Association estimation was performed with multivariate logistic regression analysis. Results. Patients with recurrent MI much more often had TNFα, IL1B, TGFB1b, FGB, ITGB3 and LPL allele and genotype polymorphism. Moreover the risk of MI increased significantly in a case of combination of FGB (alleles and genotypes) and TNFα (alleles and genotypes) gene polymorphisms (OR = 4.04, 95% CI = (1.895-8.615), p = 0.0001). Conclusion. Thus, FGB, LPL, TNFα, TGFB1b and ITGB3 gene polymorphism are associated with more severe coronary heart disease and may be a risk factor of recurrent MI development. The dominant total contribution of the FGB (rs1800788) and TNFα (rs1800629) polymorphic genes to the development of recurrent MI in the population of the middle Volga region was revealed

    Inaugural Speech as A Tool of Forming Speech Portrait of the President

    Full text link
    The paper deals with the inaugural speeches of Vladimir Putin (2018) and Donald Trump (2017) and is aimed at analyzing the role of verbal means in forming the speech portraits of political leaders. The article is of urgent interest as it demonstrates the speech portraits of country leaders in relation to national identity, mentality and socio-political course of the country. By means of comparative content analysis we looked for grammatical, lexical and stylistic elements peculiar to a specific linguistic persona while comparing the speeches of the presidents as well as we attempted to determine the specific national backgrounds of political discourse. Thus, each president's inauguration context model is mostly characterized by a different set of linguistic means. The paper findings may be useful for researchers who deal with interdisciplinary studies, political and cognitive linguistics, political discourse and communication analysis
