This paper deals with the possibility of application of aluminum phthalocyanine (AlPc) nanoparticles in clinical practice. AlPc fluoresces in the molecular form but in the form of nanoparticles it does not. Separation of molecules from an AlPc nanoparticle and therefore the appearance of fluorescence occurs under the effect of a number of biochemo‐physical factors. Owing to this feature the application of AlPc nanoparticles followed by the measurement of fluorescence spectra is proposed as a diagnostics method. It was shown that after AlPc nanoparticle application on a tooth surface the fluorescence intensity in the enamel microdamage area is 2–3 times higher than that in the normal enamel area. The appearance of fluorescence after application of AlPc nanoparticles on skin autografts testifies to the presence of inflammation. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

The article reveals the topic of the place and role of the Vkontakte social network in the organization of the educational process, the relevance of which was confirmed during the Covid-19 pandemic. The object of the research is digital education at Russian universities. The subject of the research is the VKontakte social network as a means of organizing the educational process. The authors share the experience of using social networks, accumulated in the process of teaching social disciplines at the Timiryazev Academy. The data proving the popularity of this network among students in Russia are presented. The main scientific result: not only the high efficiency of using the VKontakte social network for organizing the educational process has been proven, but also a proposal is formulated to consider digital literacy and knowledge of modern digital technologies as one of the qualification requirements for higher school teachers.

Formation and development of the Talysh ethnic consciousness under the conditions of the Talysh 'geoethnic reserve' have been analyzed. Certain ethnoforming elements of the Talysh culture, i.e. factors promoting preservation of the basic constants of the Talysh ethnic consciousness, have been revealed. On the one hand, it is a cult of rocks, stones, groves and trees, and on the other hand it is worship of air, water, land and fire, which with the appearance of Zoroastrianism at first, and later of Shia Muslim, were not absorbed and peripheralized, but filled with new religious and ethical contents presenting moral and esthetic ideals of the Talysh people. The role of a myth and religion as an obligatory early stage of formation of the Talysh ethnic culture has been determined; regularities of formation of the Talysh ethnic consciousness have been shown; steps of ethnogenesis and a world view of the Talysh ethnos have been enlightened. Introduction of strange cultural tradition components could not eliminate the existing valuable attitude of 'the geoethnic reserve', but right opposite, they created syncretic environment stimulating evolution of the Talysh ethnic consciousness towards world judgment in the system of moral and ethical images considerably enriching the Talysh ethnos outlook. Having been formed this syncretic environment effected significantly the Talysh ethnos social attitude, as well as, predetermined a prevalent character of religious values in Talyshes spiritual and socio-political life.
