The article considers the areas of structural transformations aimed at enhancing the investment interaction of the EAEU member states, including the creation of joint companies and industries, measures to activate the industrial integration.

The article is devoted to the practical aspects of the implementation of the circular economy concept. The best practices of circular business models from foreign and domestic experience have been studied and systematized. It is concluded that they are not widely spread out in the Republic of Belarus with the predominance of the “Resources recovery” business model only, while the competitive advantages of using other circular business models are becoming more and more obvious all over the world. The role of digital, engineering and hybrid technologies in the practical implementation of the circular business models considered in the article is determined.

The article of the well-known researcher of Belarusian folk art considers one of its unique and little-known phenomena, which still lives and develops in some villages and localities thanks to the talent of local masters and enthusiasm of their followers.

The article analyzes the strategy of sustainable development of the Republic of Belarus for the period until 2030 as a set of principles and requirements for the socio-economic and political systems of the state. The necessity of a comprehensive balanced and targeted improvement of the three components of sustainability is substantiated: human - economy - ecology.

The results of studying the effect of light with different spectral composition on the morphogenesis of wild-type of Arabidopsis thaliana (Col 0), as well as wei8-1tar1-1 and ahk2 mutants with modified signal transduction processes of auxins and cytokinins. We used a specially developed technique that simplifies the assessment of the effect of light on the growth and development of A. thaliana plants, especially the configuration of their root system during the entire growing season. Luminescent (LL) and light-emitting diode (LED) light sources were used, which made it possible to vary the physiologically significant blue (B), green (G), red (R), and far red (FR) spectral ranges. The R/B ratio was equal to 1 and 4 for LED 1 and LED 2 lighting options, respectively, at the same total flux density of B and R light photons. The ratios of R/FR and B/G in the spectra of LED illumination varied in the ranges closest to those observed in natural conditions. The most effective for the formation of the root system, rosette of leaves and inflorescences of A. thaliana (Col 0) was LED illumination with R/B = 4, B/G = 1 and R/FR = 6. The obtained data indicate an important role of AHK2 histidine kinase receptors in stimulation of the formation of vegetative organs of A. thaliana in response to an increase in the level of R and a decrease in B light (an increase in the R/B ratio) in complex spectral compositions. At the same time, LED lighting with a higher level of B and a low level of R light (R/B = 1, B/G = 2 and R/FR = 3) rather effectively stimulated the accumulation of the dry mass of the root system and the formation of inflorescences compared to fluorescent lighting. Stimulation of root growth by light of this spectral composition is probably mediated by a significant increase in the level of endogenous auxins. The decrease in the R/FR ratio in the spectrum of LED sources compared to the fluorescent lamp contributed to the stimulation of flowering of A. thaliana, regardless of the nature of the mutation and despite other differences in the spectral composition.

The health care system in Great Britain is considered, as well as the economic effectiveness of its functioning in comparison with the major European countries and Belarus. We considered the institutional features of its modern improvement, and made an attempt to measure the effectiveness of innovations in the healthcare system. Cost-effectiveness, its content, indicators and influencing factors have been sufficiently studied in the Russian literature. However, little attention is paid to the specificity of indicators that related to the non-productive sphere, especially the effectiveness of institutional reforms in it and to the regulative role of the state. The health care system аs any makes the greatest contribution to the preservation and increase of human capital, so it has every right to be considered a second-level production sphere, where is formed the most important factor of social production. A comparative analysis of the effectiveness of institutional and legal changes in the healthcare system of the leading countries allows us to identify the horizons of the strategic health policy in Belarus.

In the course of the work, the parameters of respiration of mitochondria of brain homogenates and the content of ATP synthase in rats with cerebral ischemia and under conditions of administration of ω-3 polyunsaturated fatty acids were studied. ω-3 polyunsaturated fatty acids have an anti-inflammatory effect due to their incorporation into the phospholipid layer of cell membranes of monocytes, leukocytes, endothelial cells, which is accompanied by a decrease in the production of inflammatory mediators and a decrease in leukocyte adhesion to the endothelial wall. Polyunsaturated fatty acids regulate vascular tone and prevent vascular vasoconstriction under the influence of catecholamines, which causes a moderate vasodilatory effect. ω-3 polyunsaturated fatty acids have a corrective effect on mitochondrial respiration, their beneficial effect on the structures of the hippocampus in conditions of subtotal cerebral ischemia and a lesser severity of manifestations of neurological deficit, compared with the group without their administration, are noted.
