ABSTRACT

This data article is related to the previous research, which addressed the development of a COVID-19 recombinant vaccine candidate. Here, we present the additional data in support of the safety and protective efficacy evaluation of two COVID-19 vaccine candidates based on the coronaviruses' S protein fragments and a structurally modified plant virus - spherical particles. The effectiveness of the experimental vaccines was studied against the SARS-CoV-2 virus in an in vivo infection model in female Syrian hamsters. The body weight of vaccinated laboratory animals was monitored. The histological assessment data of the infected with the SARS-CoV-2 virus hamsters' lungs are provided.

ABSTRACT

We present the results of a prospective multicenter study of risk factors, etiology, clinical features, and treatment outcomes for mucormycosis in patients with COVID-19 (COVID-M) in the Russian Federation. The study included 60 adult patients with COVID-M. To analyze risk factors for COVID-M, we conducted a case-control study. The control group included 60 adult patients with COVID-19 without mucormycosis. To analyze the clinical manifestations of COVID-M, we created a control group of hematological patients with mucormycosis examined in 2011-2020. In patients with COVID-19, the risk of developing mucormycosis was significantly increased with diabetes mellitus (OR=49) and overweight (OR=4,75), as well as with the use of high (>=100 mg per day for prednisolone) doses of glucocorticosteroids (OR= 4,762), especially >=10 days (OR=25,4). The main localization of mucormycosis in patients with CO-VID-19 was the paranasal sinuses (95%) and the orbit (68%). Involvement of >=2 organs was identified in 70% of patients. The main causative agents of mucormycosis were Rhizopus arrhizus (43%) and unidentified mucormycetes (36%). 90-days overall survival of patients with mucormycosis and COVID-19 - 71%. The stay in the ICU (p=0,01), the use of mechanical ventilation (p=0,0481), the presence of CVC (p=0,049), CNS damage (p=0,016) and >= 2 organs (p=0,048) significantly worsened the prognosis of the disease. The best prognosis was in patients who received antifungal therapy (p=0,03875) and surgical treatment (p=0,046).Copyright © 2022 Authors. All rights reserved.

ABSTRACT

During the pandemic, an urgent task has become to develop new vaccine platforms that will help fight the infection caused by SARS-CoV-2 and quickly respond to newly emerging pathogens. Plant viruses can make a significant contribution to the solution of this problem. Phytoviruses, having the properties of any viral particles (self-assembly, immunogenicity, nanosize), are safe for humans since plants and mammals have no common infectious agents. As a result of thermal rearrangement of the tobacco mosaic virus, spherical particles of a protein nature have been obtained, which have unique immunostimulation and adsorption properties and can play the role of a universal adjuvant platform to create vaccines. Based on these particles, a scheme for obtaining vaccine preparations is proposed. This technology resembles a toy construction set for children. The basis is spherical particles, on the surface of which there are toy blocks-antigens. The "blocks" can be removed, added, or replaced, and this does not take much time and resources. Based on spherical particles, a polyvalent vaccine candidate against COVID-19 has been created as an adjuvant platform.

ABSTRACT

Introduction. The problem of identifying the role of contemporary art thesauri in the teaching profession development has become aggravated in the context of global socio-economic changes, apparently irreversible after the COVID-19 pandemic. Contemporary art, actively exploring the reality of the digital age, makes it possible to comprehend the essence of the new in education, clearly see the ideal of a person who is in demand by the society of the 2020s, and choose a way to overcome the crisis of the teaching profession, which is no longer limited by the framework of person-to-person duality but is fundamentally open due to technology. The research purpose is to generalize scientific ideas for the study of contemporary art thesauri as a tool for developing the teaching profession in the cultural-educational space of the 21st century. The research methodology includes the thesaurus, interdisciplinary and integrated approaches;identification and systematization of units of knowledge about contemporary art through thesauri influencing the development of the profession of a teacher. The use of a thesaurus approach made it possible to identify and systematize units of knowledge about contemporary art and its educational opportunities that coincide in one way or another. An interdisciplinary approach showed the mechanism of integrating disciplines studied by future teachers with the space of modern artistic culture. An integrated approach was used to view contemporary art as a hierarchical system of a high degree of complexity in specific historical and psychological aspects. The research results contain a generalized description of the process of integrating contemporary art into education: the transition from a teacher’s professionalism to transprofessionalism through the introduction into the widespread practice of approaches that have resulted from the activities of representatives of creative professions;increasing the significance of a teacher as an organizer of cultural activities in the context of distance learning, with the emergence of new professional roles;the formation of concepts reflecting the commonality of thinking of a teacher and an author of artworks. Findings. Contemporary art thesauri help pedagogical education get to a higher level due to a new understanding of the profession of a teacher: as developing from professionalism to transprofessionalism through the assimilation of knowledge about the formation of a professional in the art sphere (“alien” becomes “own”), focused on organizing students’ cultural activities using distance technologies and new professional roles, explaining itself in terms of pedagogy and art. The field of application of research findings is the improvement of educational programs at all education levels (from the preschool establishment to university) in accordance with the requirements of state standards. © 2021 LLC Ecological Help.
