[The elderly and the digital services of psychological counselling in modern Russia.].

The article presents the results of a sociological study of the process of digitalization of psychological counselling in modern Russia. Digital psychological counselling services have been actively developing in recent years, however, the elderly are still not considered by managers and marketers of the services as their target audience. The digital divide plays a significant role in this exclusion, which is inextricably linked with other forms of inequality from geographic to economic.

Hybridization and polyploidization within the Chenopodium album aggregate analysed by means of cytological and molecular markers.

Hybridization and polyploidization represent an important speciation mechanism in the diploid-polyploid complex of the Chenopodium album aggregate. In the present study we successfully reconstructed the evolutionary histories of the majority of Eurasian representatives of the C. album aggregate, resulting in the most comprehensive phylogenetic analysis of this taxonomically intricate group of species to date.

[Functional reserves of the pituitary gland in patients with trophoblastic uterine tumors].

In patients with chorionepithelioma as distinct from the normal postnatal period hypothalamohypophyseal function has been shown to get loose without the parallel elimination of the hormones of the fetoplacental complex from the body, particularly of chorionic gonadotrophin.

[Pituitary gonadotropic function in uterine trophoblastic tumor].

A simultaneous determination of 3 gonadotropic hormones of the hypophysis (follitropin, lutronin and prolactin) using a radioimmunoassay in 33 patients with trophoblastic uterine tumors and 22 women on the 1st-8th day after normal delivery, has shown that there are not only significant differences in the nature of the secretion of hypophyseal gonadotropic hormones in pathology as compared to the normal postnatal period but also differences in different forms of trophoblastic tumors. These differences were characterized by a progressive, according to the severity of disease, independence between trophoblastic tissue function and gonadotropic function of the hypophysis. A marked suppression of follicle-stimulating function of the hypophysis after normal delivery decreased hydatidiform mole and trophoblastic tumors and was not observed in patients with chorioepithelioma of the uterus.
