RESUMO
The importance of YWHAE gene polymorphisms (rs1532976, rs3752826, and rs9393) in the development of suicidal behavior has been studied in ethnic groups of Russians and Tatars from the Republic of Bashkortostan. It was revealed that the carriers of the YWHAE*C allele of rs3752826 polymorphism of the YWHAE gene have increased the risk of suicidal behavior (OR = 1.91), regardless of their ethnicity. In addition, the YWHAE*T allele of rs9393 polymorphism (OR = 2.21), YWHAE*T/*T genotype (OR = 2.73), and YWHAE*T allele (OR = 1.52) of the rs1532976 polymorphism, as well as the YWHAE*A*T haplotype of rs1532976 and rs9393 polymorphisms (OR = 1.54) represent genetic markers of the risk of suicidal behavior in the sample of subjects of Russian ethnicity.

Various clinical strains of Enterobacter cloacae have been examined for the presence of site-specific endonuclease activities. Restriction endonucleases of class II have been isolated from six strains. Recognition sequences for all of these endonucleases were determined and the cleavage sites were identified for two of them. The enzymes prove to be isoschizomers of EcoRII and PstI. Restriction endonucleases Ecl2zI and Ecl37kI recognise the nucleotide sequences CTGA/G and are true isoschizomers of PstI. The genes for Ecl54kI and Ecl57kI restriction-modification systems (isoschizomers of EcoRII) were found to be located on the IncN group plasmids, whereas the genes for Ecl2zI and Ecl99kI seem to be located on the chromosomes of host cells.
