“…In the case of selenium-enriched fibroin, the minimum corresponding to EWC almost disappears. Thus, the introduction of selenium into the fibroin structure decreases the number of SSCs and leads to a preferential increase in the amorphous part of the polymer [110]. Fibroin is known to consist of hydrophobic and hydrophilic amino acid residues and is highly hygroscopic.…”

This chapter summarizes the latest information on the main differences in the chemical properties of selenium proteins and their sulfur analogues, Se proteins and their functions, Se-accumulating proteins, the relationship between Se and hemoglobin, Selenium in gerontology, Selenium and iodine deficiency conditions, Se and immunity, Selenium as an antioxidant in nitrite poisoning. Also discussed are some of the results of the first studies on protein enrichment with selenium carried out in the seventies of the last century. This native protein was natural silk fibroin. Fibroin has since become an important tool for human health and healing. It was discovered that when selenium-containing inorganic compounds were added to mulberry silkworm feed, selenium atoms formed additional sulfur-like bonds in fibroin macromolecules. This resulted in additional branching of protein macromolecule. Selenium atoms in the fibroin structure have a sufficiently high electron affinity, act as small traps and capture migrating electrons. This leads to a reduction of free radicals, which are generated by external influences such as mechanical, thermal, electrical and radiation.

Relevance. The relevance of this study is underscored by the pivotal role of teachers in fostering educational innovation and amalgamating diverse pedagogical traditions. Purpose. The purpose of this study is to explore the development of reflective abilities in future biology teachers during their university training in Kazakhstan. Methodology. The main research methodology employed in this study involved the use of surveys administered via Google Forms. Participants included 18 secondary school biology teachers and 63 third-year biology students in Kazakhstan. For teachers, open-ended questions were utilized to gauge their perspectives on the role of reflection in teaching, while students responded to statements via a structured questionnaire. Results. The results of the survey revealed insufficient levels of reflective activity among both biology teachers and students. These findings underscore the need for targeted interventions aimed at bolstering reflective practices within teacher training programs. Subsequent analysis oriented towards enhancing methodological training through various strategies, including optimizing the educational environment, incorporating innovative teaching methodologies, and fostering inclusive dialogues on pedagogical challenges. Conclusions. In conclusion, the study delineates a strategic roadmap for enhancing reflective teaching practices among future biology educators. By cultivating introspective skills and fostering inclusive dialogue, educators can optimize professional responses, mitigate pedagogical crises, and bolster the efficacy of instructional decision-making.

Relevance. The relevance of the study stems from the fact that adolescence is a crisis age and young men's lives are being restructured both emotionally and in terms of values. Age-related changes entail learning new skills and modifying behavioural patterns in order to cope effectively with life's challenges. Purpose. The aim of the study is to examine the relationship between emotional intelligence and subjective well-being. The analysis of the issues was conducted using a theoretical and practical research framework. The theoretical framework is based on the methods of analysis, synthesis, generalisation, comparison and classification. The practical part consisted of testing and processing the results. Methodology. The following research methods were chosen for testing: the C. Ryff's psychological well-being scale and the D. Lyusin's emotional intelligence questionnaire. Results. The results were processed using Pearson's statistical correlation coefficient. The sample for the study consisted of 168 participants. An analysis of the theory regarding the indicators under study makes it clear that no single definition of 'subjective well-being' has emerged in scientific sources, but scientists have identified a number of factors and components in its structure that somehow influence the level of development of subjective well-being of the individual, which in turn influences the quality of life as a whole. Conclusions. Practical research suggests that there is a direct correlation between the level of development of emotional intelligence and the level of subjective well-being. The research materials will be useful to workers in the field of social and psychological work, practical psychologists of higher educational institutions, specialists in professional guidance work, and social pedagogues.
