Abstract:

ABSTRACT The virophage Sputnik is a satellite virus of the giant mimivirus and is the only satellite virus reported to date whose propagation adversely affects its host virus' production. Genome sequence analysis showed that Sputnik has genes related to viruses infecting all three domains of life. Here, we report structural studies of Sputnik, which show that it is about 740 Å in diameter, has a T=27 icosahedral capsid, and has a lipid membrane inside the protein shell. Structural analyses suggest that the major capsid protein of Sputnik is likely to have a double jelly-roll fold, although sequence alignments do not show any detectable similarity with other viral double jelly-roll capsid proteins. Hence, the origin of Sputnik's capsid might have been derived from other viruses prior to its association with mimivirus.

Abstract:

The first universal exhibition of the post-Second World War era and a major battleground in the ‘cultural Cold War’, the 1958 Brussels Exposition served as an appropriate venue for the display of Sputniks I and II. As the centerpiece of the enormous Soviet pavilion, the Sputnik replicas enabled the USSR to bask in the reflective glow of its scientific and technological achievement before an international audience of 40 million. Based on archival sources (from Brussels and Moscow) as well as contemporary published material, this article employs a modified version of Stuart Hall's reception theory to analyze Soviet authorities' production (or ‘encoding/writing’) of the exhibit and its appropriation (‘decoding/reading’) by radically different publics – non-Soviet visitors and Soviet readers back home. It argues that the producers exercised only tenuous control over the meaning of Sputnik.

Abstract:

The article deals with issues of countering cyber-attacks (so-called trolling and hacking) in Internet broadcasting, and using social networks in info-competition and communication discourse in German-language on-air, by the example of International News Agency “Russia Today” (RT) and its website Sputnik. The topicality of the article is based on the fact that RT’s website Sputnik is a relatively new resource on the European information market. The author analyzes the cases and contexts of countering malware and targeted cyber-attacks on European German-language broadcasting agencies. The study of RT’s and Sputnik’s journalists’ work shows that it is actively hindered by some Western countries, particularly the USA and the UK, which are obsessed by anti-Russian xenophobia and the unproved pre-conception of Russia’s interference with their internal affairs. These countries openly admit to be waging an outreach war against Russian broadcasting companies by means of hacking attacks. Russian multi-language broadcasting channel RT, founded in 2005, successfully reflects and transmits Russia’s official position on key issues of the international politics and countering cyber-attacks by foreign “trolls” and “hackers”. A website is currently the most easily accessible among all digital communication channels, and its quality is easy to assess. Considering this, the author describes advantages of RT’s transition from social networks to its German-language site Sputnik. The measures taken in order to optimize its structure, adapt to mobile devices, and provide convenience of site navigation, enabled Sputnik to enlarge its geographic reach and enter the circle of foreign German-language social networks. Keywords. Internet broadcasting, broadcasting, cyber-attacks, information war, trolling, hacking, German-speaking audience, management of news, International News Agency “Russia Today” (INA RT), website Sputnik, Internet media, social networks, RIA Novosti.

Abstract:

Background: Currently, left ventricular assist devices (LVADs) are a successful surgical treatment for patients with end-stage heart failure on the waiting list or with contraindicated heart transplantation. In Russia, Sputnik 1 LVAD was also successfully introduced into clinical practice as a bridge-to-transplant and a destination therapy device. Development of Sputnik 2 LVAD was aimed at miniaturization to reduce invasiveness, optimize hemocompatibility, and improve versatility for patients of various sizes. Methods: We compared hemolysis level in flow path of the Sputnik LVADs and investigated design aspects influencing other types of blood damage, using predictions of computational fluid dynamics (CFD) and experimental assessment. The investigated operating point was a flow rate of 5 L/min and a pressure head of 100 mm Hg at an impeller rotational speed of 9100 min−1. Results: Mean hemolysis indices predicted with CFD were 0.0090% in the Sputnik 1 and 0.0023% in the Sputnik 2. Averaged values of normalized index of hemolysis obtained experimentally for the Sputnik 1 and the Sputnik 2 were 0.011 ± 0.003 g/100 L and 0.004 ± 0.002 g/100 L, respectively. Conclusions: Obtained results indicate obvious improvements in hemocompatibility and sufficiently satisfy the determined miniaturization aim for the Sputnik 2 LVAD development.

Abstract:

The research examined linguocultural features of media coverage of the Great Victory anniversary the Sputnik agency (Russia Today). The purpose of the study was to determine, from the standpoint of linguistic cultural studies, the key images that formed the media. The object of the research is the materials of three editions of the Sputnik agency (Sputnik Polska, Sputnik International, Sputnik Türkiye), the geography of distribution and the composition of the audience of which reflect differentiated linguocultures. A set of methods is used: content analysis; contextual analysis, comparative analysis, case study. The empirical base was made up of publications dedicated to the 75th anniversary of Victory in the Great Patriotic War, posted on the websites of the editorial offices of Sputnik Polska, Sputnik International, Sputnik Türkiye. Sample type: solid. Chronological scope of the study: April 15 — May 15, 2020. Based on the results of the study, we concluded that the nature of representation is directly related to linguocultural characteristics and is due to historical, political and sociocultural preconditions. At the same time, all editions are united by the commonality of the constructed images: Victory Day (attitudes towards victory over fascism in the international arena); nations (both winners and losers); preservation of historical memory. The presence or absence of certain stable linguistic units depends on the cultural and ethnic specifics of the audience. The greatest efficiency from the standpoint of the implementation of international broadcasting activities (transmission of cultural codes and meanings) is achieved in a situation of a common / close mentality, interaction of ethnic groups and territorial proximity.

Abstract:

Left ventricular assist devices provide circulatory support to patients with end-stage heart failure. The standard operating conditions of the pump imply limitations on the rotation speed of the rotor. In this work we validate a model for three pumps (Sputnik 1, Sputnik 2, Sputnik D) using a mock circulation facility and known data for the pump HeartMate II. We combine this model with a 1D model of haemodynamics in the aorta and a lumped model of the left heart with valves dynamics. The model without pump is validated with known data in normal conditions. Simulations of left ventricular dilated cardiomyopathy show that none of the pumps are capable of reproducing the normal stroke volume in their operating ranges while complying with all criteria of physiologically feasible operation. We also observe that the paediatric pump Sputnik D can operate in the conditions of adult circulation with the same efficiency as the adult LVADs.

Abstract:

In modern political and socio-cultural realities, a special role and importance are assigned to international broadcasting as a technology for positioning a content-producing country in the external environment, i. e. the global media space. The subject of this study is the explication of the specifics of the linguocultural organization of international broadcasting. The experience of Russia Today was taken as the flagship of international broadcasting in the Russian segment of the media space, through its activities influencing the formation of the geopolitical situation in the modern globalizing world. A complex of methods was used: historical and political analysis, structural analysis, contextual analysis, secondary analysis of sociological and statistical data. The empirical base was made up of four editions of the Sputnik Agency (Sputnik International, Sputnik Polska, Sputnik Trkiye, and Sputnik Belarus), representing various linguocultures - with differentiated ethnic and religious characteristics that have not only linguistic but also cultural manifestations in general. Based on the results of the study, it is concluded that the linguocultural organization of international broadcasting is considered as a means of implementing the diplomatic mission of the state-broadcaster with soft power tools in the globalizing world. It is based on the representation of positioning content, taking into account ethnicity, religion together with the linguistic and cultural characteristics of the audience. Both the effectiveness of promoting program statements and ideas and strengthening the countrys geopolitics depend on the degree of linguocultural orientation of international broadcasting activities.

Abstract:

Background and Aim: The coronavirus disease 2019 (COVID-19) vaccine helps to develop immunity to SARS-CoV-2, the virus that causes COVID-19, in most cases preventing the disease. Although various brands of vaccines work in different modes, all COVID-19 vaccines prompt an immune reaction to make the body remembers how to protect from the virus in the future. The present study aims to evaluate the safety and the immune response for mixing of Sputnik V and AstraZeneca COVID-19 vaccines on mice. Materials and Methods: Our experimental study was performed on mice weighing on average of 20 g, selected by random allocation. The mice were divided into four groups of 12. Group one received a single dose of 0.5 ml Sputnik V COVID-19 vaccine, group two received two doses of 0.5 ml AstraZeneca COVID-19 vaccine, group three received two doses of 0.5 ml Sputnik V together with 0.5 ml AstraZeneca COVID-19 vaccine and group four received two doses of 0.5 ml of 0.9 % NaCl. Results: Our study shows that mixing of Sputnik V and AstraZeneca COVID-19 vaccines is safe and induces good immunity for mice. Conclusion: Mixing of Sputnik V and AstraZeneca COVID-19 vaccines creates no problems and provides good immunity to mice and may be an interesting technique to help to overcome shortcomings of one or the other vaccine. Further toxicity studies are required to assess potential hazards for humans to evaluate the histopathological characteristics.

Abstract:

Abstract Designing a ventricular assist device is a complex technological process, and testing a finished product requires a significant investment of money and time. Simulation allows research to conduct research early in the development of a device, thereby reducing time and material costs. In this work, the calculation of hemolysis in the left ventricular assist device Sputnik (Sputnik LVAD) is carried out. Three different levels of circulatory support were chosen. For the first level, the following parameters were selected: blood flow rate of 2 L/min. at a rotor speed of 8000 rpm; for the second - 4 L/min, 8500 rpm; for the third - 6 L/min, 9000 rpm. The distribution of scalar shear stresses and the index of hemolysis were obtained from the pathlines of the particles. When comparing three operating points of LVAD Sputnik, hemolysis indices were obtained using the Lagrangian model. The mean hemolysis indeces were 0.0284%, 0.0210%, 0.0155% for LVAD Sputnik operating at a fixed rate of 2, 4, 6 L/min at a pressure of 100 mm Hg, respectively. The calculation results show that the capacity of 6 L/min is better than 2 and 4 L/min.

Abstract:

Background There is a limited amount of data on the safety profile of the COVID-19 vector vaccine Gam-COVID-Vac (Sputnik V). Previous infodemiology studies showed that social media discourse could be analyzed to assess the most concerning adverse events (AE) caused by drugs. Objective We aimed to investigate mild AEs of Sputnik V based on a participatory trial conducted on Telegram in the Russian language. We compared AEs extracted from Telegram with other limited databases on Sputnik V and other COVID-19 vaccines. We explored symptom co-occurrence patterns and determined how counts of administered doses, age, gender, and sequence of shots could confound the reporting of AEs. Methods We collected a unique dataset consisting of 11,515 self-reported Sputnik V vaccine AEs posted on the Telegram group, and we utilized natural language processing methods to extract AEs. Specifically, we performed multilabel classifications using the deep neural language model Bidirectional Encoder Representations from Transformers (BERT) “DeepPavlov,” which was pretrained on a Russian language corpus and applied to the Telegram messages. The resulting area under the curve score was 0.991. We chose symptom classes that represented the following AEs: fever, pain, chills, fatigue, nausea/vomiting, headache, insomnia, lymph node enlargement, erythema, pruritus, swelling, and diarrhea. Results Telegram users complained mostly about pain (5461/11,515, 47.43%), fever (5363/11,515, 46.57%), fatigue (3862/11,515, 33.54%), and headache (2855/11,515, 24.79%). Women reported more AEs than men (1.2-fold, P<.001). In addition, there were more AEs from the first dose than from the second dose (1.1-fold, P<.001), and the number of AEs decreased with age (β=.05 per year, P<.001). The results also showed that Sputnik V AEs were more similar to other vector vaccines (132 units) than with messenger RNA vaccines (241 units) according to the average Euclidean distance between the vectors of AE frequencies. Elderly Telegram users reported significantly more (5.6-fold on average) systemic AEs than their peers, according to the results of the phase 3 clinical trials published in The Lancet. However, the AEs reported in Telegram posts were consistent (Pearson correlation r=0.94, P=.02) with those reported in the Argentinian postmarketing AE registry. Conclusions After the Sputnik V vaccination, Russian Telegram users reported mostly pain, fever, and fatigue. The Sputnik V AE profile was comparable with other vector COVID-19 vaccines. Discussion on social media could provide meaningful information about the AE profile of novel vaccines.

Abstract:

The presented work contains an analysis of seroprevalence, tension, and duration of post-vaccination immunity to the SARS-CoV-2 coronavirus in the residents of the Republic of Belarus after immunization with two vaccine preparations available in the country: Sputnik V and Vero Cell.It was found that seroconversion after the injection of the Vero Cell vaccine occurred significantly later than after the Sputnik V vaccine (p < 0.001). Nevertheless, two-stage immunization with the vaccines provided a sufficiently high efficiency of the inoculated antibodies to the S protein of the COVID-19 pathogen: the proportion of seropositive persons reached 99.19 [96.89; 99.97] % for Sputnik V and 96.03 [90.81; 98.53] % for Vero Cell. The efficiency of antibody formation after immunization with the Vero Cell vaccine was lower in older persons (in the group > 65 years). The proportion of individuals with the highest IgG score for the SARS-CoV-2 S protein was higher after the Sputnik V administration compared to that in response to the Vero Cell vaccine (p < 0.05), and gradually decreased over time. However, no significant decrease in the level of seropositive individuals after 90 days from the start of immunization with the both vaccine preparations was detected. In COVID-19 survivors immunized with the Sputnik V vaccine, the quantitative indicators of post-vaccination antibodies reached their peak values after 1 dose of the vaccine. The obtained results complement the accumulated world science and practical information on the problem of the postvaccination immunity formation in the context of the use of different drugs against COVID-19.>< 0.001).
