[Genetic diversity of cyanophages of the Myoviridae family as a constituent of the associated community of the Baikal sponge Lubomirskia baicalensis].

Molecular-genetic analysis of cyanophages of the family Myoviridae from the associated community of the endemic Baikal sponge Lubomirskia baicalensis was carried out based on the g20 gene fragment. A large cyanophage diversity according to the g20 marker gene was found in the sponge. The Baikal sponge cyanophages were shown to be similar to those inhabiting plankton. Moreover, specific cyanophage groups that are significantly different from all of the known groups inhabiting the Lake Baikal were revealed.

[Molecular-and-genetic diversity of cyanophages of the family Myoviridae in Lake Hovsgol (Mongolia)].

Cyanophages of the family Myoviridae were studied in Lake Hovsgol based on the analysis of g20 gene fragments. The analysis revealed the diversity of g20 cyanomyovirus sequences in Lake Hovsgol. It was found a great similarity of genes from the Lake Hovsgol and Lake Baikal. Distribution of closely related virus strains in these water bodies is attributed to close geographical location, direct water connection and similar hydrochemical parameters of the lakes.

[Clinical variants of sexual sadism]. / Klinicheskie varianty seksual'nogo sadizma.

Clinical variants of sadistic sexual craving (obtrusive, compulsive, and ego-syntonic) are described, based on examinations of subjects who repeatedly committed murders. Some approaches to formation of these states and their time course are shown. A clinical case is described.
