[Hepatitis B markers in southern Altaĭ inhabitants of the village of Mendur-Sokkon (the Republic of Altaĭ). HBsAg subtyping in hepatitis B virus isolates with monoclonal antibodies].

Blood samples taken from 231 native inhabitants of the village of Mendur-Sokkon located in the Republic of Altai (South-Western Siberia, Russia) were tested for the presence of virus hepatitis B (HBV) markers. 31 samples (13.4%) were found to contain HBsAg, 111 samples (48.

[Characteristics of the gene pool of Russian Old Believers in Siberia based on polymorphism of blood groups, isoenzymes, and blood proteins].

The frequency distributions of A1A2B0, Rhesus, MNSs, P, Duffy, Kell, Hp, Tf, AcP, PGM1 alleles, and haplotypes were studied in Siberian populations of Old Believers (Burnyi village, Krasnoyarskii krai, and Isetskii raion, Tyumenskaya oblast) and in ethnic Russians from Tyumenskaya oblast. Features characteristic of the genetic structure of these groups were revealed. The Siberian groups of Russians were shown to be genetically removed from European Russian populations (Tverskaya and Vologodskaya oblasts).

[Genetic analysis of the South Altaian population of the Mendur-Sokkon village, Altai Republic].

This study was a continuation of complex research on the gene pool of indigenous Siberian populations conducted at the Institute of Cytology and Genetics, Siberian Division, Russian Academy of Sciences. In the population of South Altaians from the Mendur-Sokkon village, Ust'-Kanskii raion, Altai Republic, polymorphism for the following genetic markers was studied: blood groups ABO, MNSs, Rhesus, Kell, Duffy, and P; erythrocyte acid phosphatase (AcP); phosphoglucomutase 1 (PGM1); haptoglobin (Hp); and transferrin (Tf). The genetic position of South Altaians relative to the populations of the European part of Russia, Siberia, and the Urals was estimated.

[A genetic-demographic study of the South Altaian population of the Mendur-Sokkon village (Altai Republic)].

The main demographic parameters of the population of South Altaians from the Mendur-Sokkon village, Ust'-Kanskii raion, Altai Republic, were studied. This population was classified as a growing one because the population's reproductive size was large (37%), the prereproductive part constituted the majority of the population (52%), and the average number of surviving children per spouse was 2.6.
