Progress in the mapping of population genetic substructure provides a core source of data for the reconstruction of the demographic history of our species and for the discovery of common signals relevant to disease research: These two aspects of enquiry overlap in their empirical data content and are especially informative at continental and subcontinental(More)
This study includes 90 children (41 female and 49 male) in the age range of 2-16 years with acute disseminated encephalomyelitis (ADEM). Thirty-three patients developed ADEM following rubella infection, 26 children following varicella infection, 20 suspected viral aetiology ADEM and 11 multiphasic disseminated encephalomyelitis (MDEM). All patients had(More)
We present here the results of the Analysis of HLA Population Data (AHPD) project of the 16th International HLA and Immunogenetics Workshop (16IHIW) held in Liverpool in May-June 2012. Thanks to the collaboration of 25 laboratories from 18 different countries, HLA genotypic data for 59 new population samples (either well-defined populations or donor(More)
For the first time, an analysis of five Alu insertion loci (ACE, APOA1, B65, PV92, TPA25) has been carried out in 10 Russian populations (1088 individuals) covering the whole historical area of the Russian ethnos. Depending on the locus, Russian populations exhibit similarity to their Western (European populations) or Eastern (populations of the Ural(More)
The present experiments were directed to determine the proportions of the cholinergic and GABAergic septo-hippocampal projection neurons in NMRI mice. For the labeling of the septal neurons we used a double immunocytochemical method combined with retrograde transport of wheatgerm agglutinin apo-horseradish peroxidase-gold (WAHG) injected unilaterally into(More)
It has been proposed that the Delta32 mutation in the chemokine receptor gene, inducing resistance to HIV-1 and, probably, to other virus infections, has undergone selection in historical times. The frequency of this mutant allele has changed rapidly both in time (during the last two millennia) and in space (across Eurasia). We compiled a global database on(More)
HLA class II alleles were determined by PCR-SSO and PCR-SSP typing of DNA samples from 55 Nentsy, 81 Saami and 73 Pomor individuals from the North-European part of Russia. The results were compared with similar data from Russians. A high frequency of the DRB1*04-DQA1*0301-DQB1*0302 haplotype and a low frequency of the DRB1*11-DQA1*0501-DQB1*0301 haplotype,(More)
We investigated the contribution of the septo-hippocampal cholinergic and GABAergic system to spatial and nonspatial aspects of learning and memory that had previously been found to correlate with the extent of the hippocampal intra- and infrapyramidal mossy fiber projection in different inbred mouse strains. The following cholinergic and GABAergic markers(More)
Simultaneous study of both external and hereditary risk factors of the development of multiple sclerosis (MS) was carried out in Moscow population. As a result of the genotyping of HLA-DR locus on the chromosome 6, there were found markers of the predisposition to MS: by HLA-DR: DR2(15) way, especially, in homozygous heredity and in the absence of such(More)
