[Development of barcode and proteome profiling of glioblastoma].

High grade glioma (glioblastoma) is the most common brain tumor. Its malignancy makes it the fourth biggest cause of cancer death. In our experiments we used several glioblastoma cell lines generated in our laboratory to obtain proteomics information specific for this disease.

[The specific features of the cocirculation of influenza viruses in the 2010-2011 postpandemic period according to the results of activities of the D. I. Ivanovsky Research Institute of Virology, Ministry of Health and Social Development of Russia].

The paper gives the results of monitoring the circulation of influenza viruses in the 2010-2011 season, that covers the second year of circulation of pandemic A(H1N1)v virus strains, and their interaction with seasonal A (H3N2) and B strains. Unlike the previous season, the beginning of an increase in morbidity was recorded in January 2011; its peak in the most of contiguous areas was noted at 5-7 weeks of 2011, with its further decline to threshold levels at week 11 of 2011. Preschool and school children were most involved in the epidemic process.

[Genetic heterogeneity and adaptive strategies of the lady beetle Harmonia axyridis pall. (coleoptera, coccinellidae)].

Analysis of microstatial variability of the phenetic composition of populations of the lady beetle Harmonia axyridis Pall. is performed in Baikal region of the Primorskii Krai. It is revealed that the phenetic composition of the Baikal H.

[Sensitivity of the epidemic and pandemic influenza virus strains to zanamivir (Relenze) in in vitro experiments].

The paper presents the results of the first Russian experience in evaluating the sensitivity of the epidemic and pandemic influenza virus strains, circulating in the period 2009-2010, to the anti-neuraminidase drug zanamivir. A complex of studies, including enzyme immunoassay, fluorometric assay and partial sequence of the neuraminidases (NA1 and NA2) from influenza A virus strain, was applied. The findings Indicate that all the test strains, including those resistant to oseltamivir, were susceptible to zanamivir.

[Molecular genetic studies of the susceptibility of epidemic influenza A(H1N1) virus strains isolated in the 2006-2009 seasons in Russia to oseltamivir (Tamiflu)].

Oseltamivir (Tamiflu) is recommended by WHO experts as a drug to treat and prevent of influenza and to create stocks if its new pandemic variant occurs. The susceptibility of influenza viruses to oseltamivir was studied by polymerase chain reaction-based techniques detecting specific mutations in the neuraminidase gene. The increase in the number of oseltamivir-resistant influenza viruses, isolated from the Russian Federation, with type 1 neuraminidase H274Y mutation from 49% (2007-20008) to 92% (2008-2009) did not depend on the frequency of oseltamivir use.
