Генетический полиморфизм и эффективность противовирусной терапии при хроническом вирусном гепатите С

Aim: to determine influence of genetic polymorphisms of hepatitis C virus and single nucleotide polymorphisms (SNPs) of patients with chronic hepatitis C on achieving sustained virological response (SVR) to antiviral therapy. One hundred blood samples of eastern-Slavonic patients with different response to the therapy were analyzed. It was determined, that among SNPs of 7 human genes only allelic variants of IL-1β, IL-28B, TGF-β1 and viral genotypes can influence on probability to achieve SVR.Цель исследования - выявить роль генетического полиморфизма вируса гепатита С, выражающегося, прежде всего, в существовании генотипов/субтипов вируса, и однонуклеотидного полиморфизма (ОНП) генов пациентов с хроническим гепатитом С в формировании устойчивого вирусологического ответа (УВО) на противовирусную терапию. Изучены образцы крови от 100 пациентов восточно-славянского происхождения с разным ответом на терапию. Установлено, что на вероятность достижения УВО среди изученных ОНП семи генов влияют отдельные аллельные варианты генов IL-1β, IL-28B, TGF-β1 и генотипы вируса

Counterpoints of modern phraseology. To the anniversary of Prof. V.M. Mokienko

The paper is timed to coincide with the 80th anniversary of the birth of Valery M. Mokienko, Doctor of Letters, Professor of Slavic Philology, Philology Department, St Petersburg State University, Honorary Chairman of the Phraseological Commission of the International Committee of Slavists. The paper reviews focal areas of the scholar’s research, lists his academic interests, the main of those being phraseology and phraseography. V.M. Mokienko proposed to detect dynamic interactions of contradictory properties of the phraseological system, to reveal the mechanism of phrase formation involving broad genetic and typological parallels to determine the nature of a phraseological unit. The method of structural and semantic modeling based on a detailed comparison of dialectal, Slavic and non-Slavic European idiomacy is the basis of modern theoretical and practical studies of the scientist’s followers. The trilogy of dictionaries edited by V.M. Mokienko distinguishes precise certification of units, references to synonymous turns, which makes it easier for the reader to navigate in the huge source material, outlines the parameters of the phraseological space close to the certified expression, and makes it possible to show the wealth of images of folk speech conveying the same semantics. © 2020 Bierich A., Lomakina O.V., Nikolaeva E.K., Seliverstova E.I., Stepanova L.I

The decline in antibodies to hepatitis C virus during antiviral therapy

The goal of the study was to analyze B-cell response to hepatitis C virus during antiviral therapy among responders and non-responders. The content of antibodies to individual structural and non-structural HCV proteins was investigated during two years in three groups of patients: initial responders, non-responders and a reference group (without therapy). Treated patients in all groups exhibited the decrease in antibodies to analyzed HCV proteins, but with different patterns. The first statistically significant differences in the decline of the virus-specific antibodies between initial responders and non-responders were observed within the first three months after the beginning of therapy. Some treated patients demonstrated the decrease in antibody levels to HCV proteins after the end of therapy. © Pleiades Publishing, Ltd. 2009

Decline of antibodies to hepatitis c virus during antiviral therapy

The goal of this study was to investigate interrelationship between changes in anti-hepatitis C virus antibody and response to antiviral therapy. The comparative quantitative analysis of antibodies to individual structural and nonstructural viral proteins was done during two years in three patient groups: initial responders, non-responders and a reference group (without therapy). All patients in the treated groups exhibited decrease in the analyzed antibodies to HCV proteins, but with different patterns. The first statistically significant difference in the decrease of virus-specific antibody between initial responders and non-responders was observed within the first three months of therapy beginning. Some treated patients demonstrated decrease in antibody levels to HCV proteins after the end of therapy

The foraminiferal zonal scale of the Devonian–Carboniferous boundary beds in Russia and Western Kazakhstan and its correlation with ammonoid and conodont scales

This paper reviews the foraminiferal biostratigraphy of the Devonian–Carboniferous (D–C) boundary beds in Russia and Western Kazakhstan. The regional records of the zonal successions of Russia are summarised from sections and boreholes of the Volga-Urals Subregion of the East European Platform (Syzran no. 401 Borehole, Melekesskaya no.1 Borehole); Timan-Pechora Province of the East European Platform (Kamenka Section); South Urals (Sikaza, Zigan, Ryauzyak and Dzerzhinka sections); Middle Urals (Pershino Section); and West Siberia, Vagai-Ishim Basin (Borehole no. 1 Kurgan-Uspenskaya), and the zonal successions of Western Kazakhstan are summarised from the Mugodzhary Mountains. Three foraminiferal biozones can be defined in the interval comprising the latest Devonian and earliest Carboniferous: Quasiendothyra kobeitusana Zone, the Tournayellina pseudobeata – remnant Quasiendothyra Zone, and the Earlandia minima Zone. The D–C boundary interval is situated within the Tournayellina pseudobeata–remnant Quasiendothyra Zone. A correlation with the ammonoid and conodont zonations is proposed, which is useful for correlating deep-water and shallow-water successions
