CITIZENSHIP IN THE STRUCTURE OF SOCIO-POLITICAL ORIENTATIONS OF RUSSIAN YOUTH: PLACE AND ROLE IN STATEHOOD STRENGTHENING

Purpose of the study: In this study, we analyze citizenship in the structure of socio-political orientations of Russian youth and explore the youth role in strengthening statehood and formation of civil society institutions. The development of active citizenship values in sociopolitical orientations of Russian youth is determined by the need to change relations between the state and society. The citizens shall develop civic responsibility and civil initiatives and control the institutions of power. Methodology: The theory of social anomie and the concept of socio-cultural crisis serve the methodological basis for this study. This theory explores the eclectic nature of citizenship ideas in the youth environment. The civilizational approach makes it possible to investigate features of citizenship idea and practice information of Western European and Russian cultural traditions. All that is methodologically significant in tracking citizenship specificity of the Russian youth. The integrated approach becomes a conceptual one in this study as it treats the citizenship of Russian youth as a complex multi-component phenomenon. This phenomenon includes moral, legal and socio-political attitudes reflecting the various aspects of relations in the "man-society-state" system. Results: We conclude that in the citizenship of Russian youth there dominate two main attitudes: liberal and paternalistic. In the liberal aspect, the young people consider citizenship to be awareness of their civil rights and responsibilities, a kind of rational and active behavior corresponding to democratic political system. Paternalistic attitudes are manifested in loyalty to the state. Paternalists consider the state to be the political institution that is solely responsible for the present and future of the young people. Applications of this study: The results allow us to understand the significance of citizenship as an ethic-legal quality of personality that strengthens Russian statehood and the importance of agreement (contract) between government and society. The results discovered the need for the citizens to be engaged in solving the state's socially significant problems. The state shall also develop a favorable institutional environment for civil socialization and self-realization of the young people. Novelty/Originality of this study: The eclectic nature of Russian youth citizenship points at hindering factors in the development of active and responsible citizenship as the youth ability to self-organize and solve socially significant problems. The main factors hindering the process of civil activity formation among the young people are the stable etatist-paternalistic traditions of political culture and institutions of Russian civil society. Although, development of youth citizenship is a well-managed process. It requires the youth policy to be the stimulating and guiding force. This force is necessary to solve the problems of legal personality type formation. Such a personality is characterized by politically and socially active civic-mindedness

Draft Genome Sequences of Strains \u3ci\u3eSalinicola socius\u3c/i\u3e SMB35\u3csup\u3eT\u3c/sup\u3e, \u3ci\u3eSalinicola\u3c/i\u3e sp. MH3R3-1 and \u3ci\u3eChromohalobacter\u3c/i\u3e sp. SMB17 From the Verkhnekamsk Potash Mining Region of Russia

Halomonads are moderately halophilic bacteria that are studied as models of prokaryotic osmoadaptation and sources of enzymes and chemicals for biotechnological applications. Despite the progress in understanding the diversity of these organisms, our ability to explain ecological, metabolic, and biochemical traits of halomonads at the genomic sequence level remains limited. This study addresses this gap by presenting draft genomes of Salinicola socius SMB35T, Salinicola sp. MH3R3–1 and Chromohalobacter sp. SMB17, which were isolated from potash mine tailings in the Verkhnekamsk salt deposit area of Russia. The analysis of these genomes confirmed the importance of ectoines and quaternary amines to the capacity of halomonads to tolerate osmotic stress and adapt to hypersaline environments. The study also revealed that Chromohalobacter and Salinicola share 75–90% of the predicted proteome, but also harbor a set of genus-specific genes, which in Salinicola amounted to approximately 0.5 Mbp. These genus-specific genome segments may contribute to the phenotypic diversity of the Halomonadaceae and the ability of these organisms to adapt to changing environmental conditions and colonize new ecological niches

A fluorescent microspheres-based microfluidic test system for the detection of immunoglobulin G to SARS-CoV-2

Background: The pandemic of the new coronavirus infection, COVID-19, is currently ongoing in the world. Over the years, the pathogen, SARS-CoV-2, has undergone a series of mutational genome changes, which has led to the spread of various genetic variants of the virus. Meanwhile, the methods used to diagnose SARS-CoV-2, to establish the disease stage and to assess the immunity, are nonspecific to SARS-CoV-2 variants and time-consumable. Thus, the development of new methods for diagnosing COVID-19, as well as their implementation in practice, is currently an important direction. In particular, application of systems based on chemically modified fluorescent microspheres (with a multiplex assay for target protein molecules) opens great opportunities. Aim: development of a microfluidic diagnostic test system based on fluorescent microspheres for the specific detection of immunoglobulins G (IgG) to SARS-CoV-2. Methods: A collection of human serum samples was characterized using enzyme-linked immunosorbent assay (ELISA) and commercially available reagent kits. IgG to SARS-CoV-2 in the human serum were detected by the developed immunofluorescent method using microspheres containing the chemically immobilized RBD fragment of the SARS-CoV-2 (Kappa variant) viral S-protein. Results: The level of IgG in the blood serum of recovered volunteers was 9-300 times higher than that in apparently healthy volunteers, according to ELISA (p0.001). Conjugates of fluorescent microspheres with the RBD-fragment of the S-protein, capable of specifically binding IgG from the blood serum, have been obtained. The immune complexes formation was confirmed by the fluorescence microscopy data; the fluorescence intensity of secondary antibodies in the immune complexes formed on the surface of microspheres was proportional to the content of IgG (r 0.963). The test system had a good predictive value (AUC 70.3%). Conclusion: A test system has been developed, based on fluorescent microspheres containing the immobilized RBD fragment of the SARS-CoV-2 S-protein, for the immunofluorescent detection of IgG in the human blood serum. When testing the system on samples with different levels of IgG to SARS-CoV-2, its prognostic value was shown. The obtained results allow us to present the test system as a method to assess the level of immunoglobulins to SARS-CoV-2 in the human blood serum for the implementation in clinical practice. The test system can also be integrated into various microfluidic systems to create chips and devices for the point-of-care diagnostics

<i>In vitro</i> study of the effect of <i>Bifidobacterium bifidum </i> probiotic strain DNA on the cell concentration and colonization properties of intestinal microsymbionts

Aim. To estimate in vitro the effect of DNA isolated from the probiotic strain Bifidobacterium bifidum 791 on the cell concentration and adhesive properties of fecal isolates of bifidobacteria and opportunistic microorganisms of different species.Materials and methods. DNA was isolated from the probiotic strain Bifidobacterium bifidum 791. Biomass containing bifidobacteria was washed from the nutrient medium. The suspension of bacteria in the buffer solution was subjected to ultrasonic disintegration with a frequency of 40 kHz three times for 30 minutes, followed by centrifugation. The supernatants were combined and purified chromatographically on CL-4B Sepharose. B. breve, B. bifidum, B. infantis, Staphylococcus aureus, Escherichia coli lac-, Enterococcus faecalis, and Candida albicans were used as test cultures, isolated from the intestines of conditionally healthy adults. Results. The nucleic acid solution with a concentration of 3.54 |jg/ml did not affect the cell number of bifidobacteria (p = 0.61). The DNA content in the solution of 14.15-21.23 jg/ml increased the titers of B. bifidum and B. breve by 2 lg CFU/ml compared to the control (p = 0.01), but did not affect the titers of S. aureus, E. coli lac-, E. faecalis, C. albicans (p = 0.73). The DNA solution stimulated the self-aggregation of bifidobacteria in 1.5-2.0 times. The ability to autoaggregate under the influence of bifidobacterial DNA in S. aureus, E. faecalis, C. albicans did not change, in E. coli lacincreased 2.3 times (p = 0.05).Conclusion. A DNA solution of the probiotic strain B. bifidum 791 with a content 14.15-21.23 jg/ml stimulates the reproduction and autoaggregation of fecal B. breve, B. bifidum

Clinical laboratory diagnostics of antibodies to SARS-CoV-2: from a QR code to the reality

Background: The immune response to SARS-CoV-2 includes the production of specific immunoglobulins to protein antigens of SARS-CoV-2. Depending on the type and level of immunoglobulins, it is possible to assess the stage of the disease and evaluate the effectiveness of vaccination. The main approach to the determination of immunoglobulins to SARS-CoV-2 in human biological fluids is enzyme-linked sorbent immunoassay. Its data, in particular, are used to issue an electronic COVID-19 certificate with a QR code. However, the qualitative and quantitative composition of immunoglobulins for a QR code is not officially regulated. Aim: measuring the immunoglobulins level in the human blood serum with different types of immunity to the new coronavirus infection (COVID-19) to select the most informative indicators of protective immunity. Methods: The study included 76 blood serum samples from male and female volunteers (age, 18 to 50 y.o.) in compliance with the ethical standards. The detection of IgA, IgM, IgG (total to different regions of SARS-CoV-2, S-protein IgG and RBD-fragment IgG), IgG avidity, and the level of the SARS-CoV-2 N-antigen was performed by enzyme-linked immunosorbent assay (ELISA) using commercially available reagent kits. Results: The indicators of the level of antibodies (both "protective" IgG and IgA of the initial phase of infection) are most pronounced in persons who have been vaccinated and have had COVID-19, and least pronounced in unvaccinated people. For recovered unvaccinated individuals, the level of total protective antibodies and IgG to the S-protein, including the RBD fragment, is the lowest; the avidity of IgG is lower than that in the other groups, too. The IgG avidity in vaccinated patients is higher than that in recovered ones. It should be noted that there were no differences in the level of both total IgG to SARS-CoV-2, to the S-protein and to the RBD-fragment of the S-protein for recovered and vaccinated individuals. Conclusion: The analysis of COVID-19 immunoglobulins indicates a different profile of the humoral immune response following vaccination and previous infection with COVID-19. To quickly assess the immune response to previous and current COVID-19 infection, as well as to detect the post-vaccination immunity, it is advisable to use the total level of IgG to SARS-CoV-2. For deeper assessment of protective immunity and production of protective antibodies, it is better to evaluate the quantitative content of IgG to the S protein and its RBD fragment. The equal level of IgA in the experimental groups indicates an ongoing interaction with SARS CoV-2 in the population. Thus, the electronic COVID-19 certificate is of little use when it is formed by only one of the indicators without taking into account the rest

Studying the Influence of Mungbean Use on the Structure-forming Indicators of Meat-plant Systems Based on Veal, Pork, Chicken Meat

This paper reports a study into the use of germinated mungbean as a promising raw material influencing the structure-forming indicators of meat systems during the production of meat-vegetable sausages. The content of iodine in the germinated mungbean and its anatomical parts has been examined using solutions of potassium iodide. A change in the phytic acid content and size of phytin globoloids has been established in mungbean malt depending on germination conditions. The influence of flour from germinated mungbean on the moisture-binding, moisture-retaining, fat-retaining abilities, as well as on the pH of meat systems based on veal meat, pork, chicken has been investigated. The reported set of studies is important as the defined patterns could make it possible to devise technologies for meat-vegetable sausages, to expand the range of enriched meat products. The result of this study has established that the degree of biotransformation of iodine into beans is influenced by the protein content in the native beans. Almost 90...95 % of iodine is accumulated in the cotyledons of beans in the protein fraction, 5...10 % ‒ in sprouts and roots. The rational range of potassium iodide concentrations in the germination solution is 76.5 g per 1,000 cm3, over 48 hours. Prolonging the germination time leads to microbiological damage to the bean mass. The germination process affects the reduction of phytic acid content, which is confirmed by a decrease in the diameter of phytin globoloids. It is rational to use in meat systems based on pork meat and veal meat 10 % of the developed flour by reducing meat raw materials. With this ratio of formulation ingredients, the maximum increase in the moisture-binding, moisture-retaining, and fat-retaining capacities of these meat systems is achieved. In the meat systems based on chicken meat, it is possible to increase a replacement part of up to 15 %. The reported set of studies is useful and important because it could form the basis for devising the technologies of meat-vegetable sausages to meet the needs of different segments of consumer

Compound phenotype in a girl with r(22), concomitant microdeletion 22q13.32-q13.33 and mosaic monosomy 22

Abstract Background Ring chromosome instability may influence a patient’s phenotype and challenge its interpretation. Results Here, we report a 4-year-old girl with a compound phenotype. Cytogenetic analysis revealed her karyotype to be 46,XX,r(22). aCGH identified a 180 kb 22q13.32 duplication, a de novo 2.024 Mb subtelomeric 22q13.32-q13.33 deletion, which is associated with Phelan-McDermid syndrome, and a maternal single gene 382-kb TUSC7 deletion of uncertain clinical significance located in the region of the 3q13.31 deletion syndrome. All chromosomal aberrations were confirmed by real-time PCR in lymphocytes and detected in skin fibroblasts. The deletions were also found in the buccal epithelium. According to FISH analysis, 8% and 24% of the patient’s lymphocytes and skin fibroblasts, respectively, had monosomy 22. Conclusions We believe that a combination of 22q13.32-q13.33 deletion and monosomy 22 in a portion of cells can better define the clinical phenotype of the patient. Importantly, the in vivo presence of monosomic cells indicates ring chromosome instability, which may favor karyotype correction that is significant for the development of chromosomal therapy protocols
