Longitudinal Changes in Acculturation for Immigrant Women From the Former Soviet Union

Abstract: Most research on immigrant acculturation has been conducted with cross-sectional samples, using statistical designs that may not capture different trajectories for the components that contribute to this complex concept The purpose of this study was to examine change over time in acculturation for 226 women from the former Soviet Union who had lived in the United States fewer than 8 years when recruited Using self-report data from four annual waves, growth trajectories were examined in four components of acculturation (American behavior, Russian behavior, English language proficiency, and cultural generativity) Results indicate that these components changed at varying rates Acculturation is a process with multiple distinct components that should be measured separately to obtain a full profile of change over time

[The 24 May, 2009 isolation of the first A/IIV-Moscow/01/2009 (H1N1)swl strain similar to swine A(H1N1) influenza virus from the first Moscow case detected on May 21, 2009, and its deposit in the state collection of viruses (SCV No. 2452 dated May 24, 2009)].

Abstract: The paper presents the results of the first isolation of the new influenza virus in Moscow and the Russian Federation, which was similar to the swine A/IIV-Moscow/01/2009(H1N1)swl strain isolated on May 24, 2009 from a Russian arrived in Moscow from the USA on May 19, 2009. The antigenic, biological, and molecular genetic properties of this virus were studied. The virus was isolated on MDCK and chick embryos, the hemagglutination titers being 1:8-1:16 AE; the infectious titers being 6.51g of the tissue cytopathogenic infective dose (TCID50) and 7.01g of the common infective dose (CID50). The virus was sensitive to arbidol, ribavirin, oseltamivir, and resistant to rimantadine. The complete virus genome was sequenced; the data were accepted to the Gen Bank on May 28, 2009 under GQ219584-GQ219590 and GQ202724. The significant gene substitution of neuraminidase Asp for Gly in position 451, which has been undetectable in any other strain published in the Gen Bank by the present time is unique only to A/IIV-Moscow/01/2009 (H1N1)swl. The virus has been deposited in the State Collection of Viruses, D. I. Ivanovsky Institute of Virology, Russian Academy of Medical Sciences, under No. 2452 dated May 24, 2009.

[Population interactions of West Nile virus (Flaviviridae, Flavivirus) with arthropode vectors, vertebrates, humans in the middle and low belts of Volga delta in 2001-2006].

Abstract: The population interactions of West Nile virus in the middle and lower regions of the Volga delta in 2001-2006 were studied. The authors established major species of the mosquitoes Anopheles messeae, An. hyrcanus, Culex piplens, Cx modestus, Coquilletidia richiardii in anthropogenic biocenoses and An. hyrcanus, Coq. richiardii in the natural ones; vertebrates - crows (Corvidae) and domestic animals in the anthropogenic biocenoses and cormorants in the natural ones. The ticks Hyalomma marginatum were found to play an active role in the circulation of the virus and in the stability of infection foci. The epicenter of an endemic area is situated in the anthropogenic biocenoses of the middle belt where high infection rates were found in humans (20-40% immune stratum), mosquitoes, and birds. A complete sequence of 14 strains was detected in 44% from 1 to 5 nucleotide replacements to a genome, most frequently at E154 positions Asn --> Ser and Ser --> Pro, which prevents glycosylation and reduces neuroinvasion. Analysis of 100 RT-PCR-positive samples revealed the absolute predominance of genotypes 1 with single findings of genotype 2 and 4.
