Ontogenesis is a complex process of morphophysiological transformations. Embryonic and postembryonic development is continuously affected by both endogenous and environmental factors, which lead to variability in morphometric parameters. The research was conducted in the laboratory of ecological embryology of the Federal State Budgetary Educational Institution of Higher Education of the North Osetian Federal University (Vladikavkaz). The results showed that under the influence of bentonite extract, the morphological parameters of green toad larvae with a brown phenotype are more variable than in larvae with an olive green phenotype in both the control and experimental groups. Thus, the embryos and larvae of the green toad with the olive green phenotype are more stable than the larvae that had the brown phenotype, both in natural circumstances and under the influence of bentonite clay extracts.

The article is devoted to the issues related to the phenomenon of “aging society”. The relevance of creating a barrier-free environment for the elderly is dictated by the current demographic trend towards an increase in life expectancy, an increase in its quality. The number of centenarians with functional impairments (senile dementia, Parkinson’s and Alzheimer’s) who require care at a qualitatively new level is increasing. Innovative form of organizing the leisure of the elderly «Kindergarten for the elderly people» is considered as one of the ways to solve the problem. Based on the data of a study conducted by the Federal state budgetary educational institution of higher education of the Far-Eastern state medical university of the Ministry of Health of Russia in 2020, identified the need to create a social institution «Kindergarten for the elderly people». The article notes the need for older people to adapt to the changing conditions of their life in the society saturated with gadgets and information.

Socialization occurs not consciously through a complex process of interactions where emotions, values, attitudes, feelings and own context cultural patterns are integrated. This process generates a relational climate that should be conducive to learning and well-being for all people in the group. The school, educational institution, favors the relationships within the group framework and reconstructs previous learning with a variety of models and the educational action led by the faculty. The amplitude of the classroom group creates situations of great complexity and offers many opportunities to prevent the violence from the knowledge of situations that may involve risks and relational vulnerability and relational difficulties especially for some people. The factors that can hinder relations and create an improper relational climate include the social and learning difficulties and cultural differences. The climate cannot be changed individually but it is modified from the dynamics led by the adult person who has the responsibility to help the group learn to relate and that each individual has their space of belonging. We present data from a population of 10891 students in primary and secondary education and the analysis of some factors affecting the climate of the group.

The paper is devoted to the analysis of the state of the equipment recycling system in Russia and the issues of improving the legislative framework that accompanies it. The role of state structures in solving the problems of forming a resource-saving ecooriented system for the disposal of decommissioned equipment is reflected. To analyze the work in the field of waste management, to reflect the state of the legislative framework for the existing system of recycling equipment in Russia and abroad, to make recommendations for its improvement. Problems with waste appear when, in the process of production and consumption of substances, objects (equipment), he/she becomes unnecessary for their owners, their owner tries to get rid of this object in the most accessible way. According to numerous information, the disposal of equipment in Russia is mainly carried out (black waste collectors), which control more than 60 % of the scrap of non-ferrous and ferrous metals, so the solution to the problem of creating an effective system for the disposal of equipment becomes not just relevant, but vital for our state. The scientific community in Russia is constantly conducting research on the creation and implementation of a system for the disposal of decommissioned equipment, so, for example, MADI scientists proposed a regional car recycling system for implementation, the scientists of the Federal State Budgetary Educational Institution FNAC VIM also developed a regional system for the disposal of agricultural recycling equipment. In order to quickly solve the problem of working out a general strategy for creating an effective system of recycling equipment in Russia, taking into account the revision of the legislative framework, it is advisable to "run-in" it at the industry level, for example, in the agroindustrial complex, with subsequent replication in other industries.

The Politeiai are one of Aristotle’s historical works. Several hundreds of fragments have come down to us. While Aristotle’s Nomima barbarika recorded the customs of the barbaric ethne, the Politeiai are generally considered to be a collection of polisconstitutions. A closer look reveals, however, that alongside a majority of Greek poleis Aristotle also included several ethne in his Politeiai, namely those in the North(west) of the Greek mainland and on the Peleponnesus. This article tries to shed light on Aristotle’s reasons for selecting these ethne. On the basis of key passages in the Politics, the author argues that their presence in the Politeiai indicates that Aristotle considered them as Hellenic, and, although inferior in status to the polis, capable of having a politeia. In Aristotle’s time, nearly all of the ethne known to have been included in the Politeiai had formed koina. While Aristotle did not explicitly discuss the federal state, he acknowledged its existence both in the Politics and the Politeiai, obviously inspired by the political reality of his time in which the koina played an increasingly prominent role, illustrated by their presence as members in Hellenic treaties alongside the poleis.

Tuberculosis (TB) is a socially significant disease for the entire world community. An important challenge in successfully combating this infection is the avalanche increase in the number of drug-resistant tuberculosis. Currently, among the reasons for the development of pulmonary tuberculosis, a complex of etiological and pathogenic factors contributing to the disruption of the immune response to M. tuberculosis and the formation of secondary immunological failure (SIF) accompanying the disease are of particular importance. However, the issues of discoordination of cellular components of the local immune system of the lungs leading to T-cell deficiency, as well as the ineffectiveness of the B-cell link, reduction of lymphocyte proliferative activity and activation of apoptosis, cytokine imbalance and activation of immunosuppression mechanisms are not fully studied and have a scattered nature, which does not allow us to assess the overall picture of violations. The goal: determining the immunophenotype of lymphocyte population in lung tissue biopsy specimens of patients with various forms of secondary tuberculosis depending on resistance in case fibrosecavernous tuberculosis (FCT). The material in the study was pulmonary tissue fragments of 30 patients with the verified diagnosis of FCT, and distributed in 2 main groups: resistant forms of secondary tuberculosis (n = 15) and 15 patients not resistant forms of secondary tuberculosis. The standard histological method was used. Immunohistochemically panel of markers included CD68, CD4, CD8, CD20, CD138. The study was conducted at the Center for the collective use of scientific equipment «Molecular Biology» of the Medical Academy named after S.I. Georgievsky in the framework of the grant № ВГ 09/2019, supported by federal state autonomous educational institution of higher education «V.I. Vernadsky Crimean Federal University». The results of the study have shown that in the conditions of secondary tuberculosis, regardless of resistance, the formation of local immunodeficiency with an immune response along the Th-2 pathway is determined. The prevalence of cytotoxic lymphocytes in the area of specific granulation tissue and the draining bronchus indicated the prolongation of inflammation and its transfer to the latent phase. The increase in the number of T-helpers and activated plasma cells can serve a reliable prognostic and diagnostic marker for the reactivation of the tuberculosis process.
