Emigration is often followed by psychic disorders. The special issue of Germans from the GUS-States immigrating to Germany is presented. The modus of paranoid reaction is discussed along the biography and the criteria of ICD 10. The acute paranoid psychosis was complicated by a neuroleptic malignant syndrome.
Alu insertions provide useful markers for the study of inter-population affinities and historical processes, but data on these systems are not numerous in Native Americans and related populations.
The study aimed to answer the following questions: (a) do the population relationships found agree with ethnic, historical and geographical data? and (b) what can heterozygote levels and associated results inform us about the events that led to the colonization of the New World?
Twelve Alu insertion polymorphisms were studied in 330 individuals belonging to South American Native, Siberian and Mongolian populations. These data were integrated with those from 526 persons, to ascertain the relationships between Asian, Northern Arctic and Amerindian populations.
A decreasing trend concerning heterozygosities and amount of gene flow was observed in the three sets, in the order indicated above. Most results indicated the validity of these subdivisions. However, no clear structure could be observed within South American Natives, indicating the importance of dispersive (genetic drift, founder effects) factors in their differentiation.
The answers to the questions are: (a) yes; and (b) an initial moderate bottleneck, intensified by more recent historical events (isolation and inbreeding), can explain the current Amerindian pattern of diversity.
We report here the genome sequence of an ancient human. Obtained from approximately 4,000-year-old permafrost-preserved hair, the genome represents a male individual from the first known culture to settle in Greenland. Sequenced to an average depth of 20x, we recover 79% of the diploid genome, an amount close to the practical limit of current sequencing technologies. We identify 353,151 high-confidence single-nucleotide polymorphisms (SNPs), of which 6.8% have not been reported previously. We estimate raw read contamination to be no higher than 0.8%. We use functional SNP assessment to assign possible phenotypic characteristics of the individual that belonged to a culture whose location has yielded only trace human remains. We compare the high-confidence SNPs to those of contemporary populations to find the populations most closely related to the individual. This provides evidence for a migration from Siberia into the New World some 5,500 years ago, independent of that giving rise to the modern Native Americans and Inuit.
Arctic peoples today find themselves on the front line of rapid environmental change brought about by globalizing forces, shifting climates, and destabilizing physical conditions. The weather is not the only thing undergoing rapid change here. Social climates are intrinsically connected to physical climates, and changes within each have profound effects on the daily life, health, and well-being of circumpolar indigenous peoples. This paper describes a collaborative effort between university researchers and community members from five indigenous communities in the circumpolar north aimed at comparing the experiences of indigenous Arctic youth in order to come up with a shared model of indigenous youth resilience. The discussion introduces a sliding scale model that emerged from the comparative data analysis. It illustrates how a "sliding scale" of resilience captures the inherent dynamism of youth strategies for "doing well" and what forces represent positive and negative influences that slide towards either personal and communal resilience or vulnerability. The model of the sliding scale is designed to reflect the contingency and interdependence of resilience and vulnerability and their fluctuations between lowest and highest points based on timing, local situation, larger context, and meaning.
Compelling evidence demonstrates chromosome 8q24 as a prostate cancer susceptibility locus. In present work we studied whether the common variants of 8q24 region, rs6983267 and rs1447295, were associated with the sporadic prostate cancer risk in the Russian population. Polymorphisms were genotyped in 393 case and 384 control Russian Caucasian men from Siberia region. The A allele of rs1447295 was significantly associated with the risk of prostate cancer (OR[CI 95%] = 1.74 [1.26-2.4], p = 7.8 x 10(-4)). A common G-A haplotype for rs6983267 - rs1447295 also showed an association with prostate cancer risk in Russian population (OR[CI 95%] = 2.03 [1.1 - 3.75], p = 0.02). We performed a meta-analysis combining our results with previous studies to evaluate the association between studied SNPs and prostate cancer risk. Meta-analysis has strongly supported the association for these SNPs (p
This article examines challenges, coping strategies, and resilience among Eveny adolescents in northeastern Siberia. It explores situations which the study participants associate with challenge and hardship, namely their experiences of transition from life in the family reindeer herding camp to schooling at the age of 7, bullying, boredom, and violence. By situating the data within the Eveny framework of resilience (khinem), the study provides the ethnographic context for coping strategies and efforts (e.g., sharing, inter- and intragenerational support, availability of safe homes) undertaken by the community in order to mitigate the situations of risk and hardship and to facilitate adolescents' resilience. The account emphasizes that instead of identifying adolescents as either resilient or vulnerable, it is necessary to explore culturally specific processes and practices which potentially contribute to their acquisition of resilience.
We assumed that persons with a Russian/Soviet cultural background have a more skeptical attitude towards psychotherapy than persons with a German background because of the poor distribution of psychotherapy and the knowledge about this kind of treatment in Russia.
We compared the views of Russian probands (n=40), Russian migrants living in Germany (n=65) and German probands (n=70) with the "Questionnaire on Attitudes towards Psychotherapeutic Treatment" (QAPT). For the study of the Russian probands we translated the questionnaire into the Russian language.
The psychometric examination predominantly suggests the quality of the Russian version of the QAPT. Russian probands showed a more skeptical attitude towards psychotherapy compared to the German probands. The migrants had a tendentially more negative attitude than the Germans and a more positive attitude than the Russians. However, we could not determine any differences concerning the anticipated social acceptance regarding participation in psychotherapy.
The results suggest the relevance of culture-specific factors in psychotherapy and an increased need for information of persons with a Russian/Soviet cultural background about psychotherapy.
Human indigenous circumpolar populations have elevated basal metabolic rates (BMRs) relative to predicted values; this metabolic elevation has been postulated to be a physiological adaptation to chronic and severe cold stress. The present study examines BMR in the Yakut, an indigenous high-latitude population from the Sakha Republic of Russia to determine (1) whether the Yakut show evidence of an elevated BMR, (2) if the Yakut display evidence of age-related changes in BMR, and (3) whether lifestyle differences influence BMR. BMR was measured during the late summer in 75 women and 50 men (ages 18-56 years) from the Siberian village of Berdygestiakh. Measured BMR (+/- SEM) of the entire sample was significantly elevated (+6.5%) compared to predictions based on body mass (6,623.7 +/- 94.9 vs. 6,218.2 +/- 84.7 kJ/day; P
