    Grapevine (V. vinifera L.) is one of the most widely cultivated species of agricultural interest. The domestication of wild grapes starting in the Neolithic Age, took place in the Near East area. The aim of this study was the genotyping of germplasm coming from Armenia, Azerbaijan, Georgia and Moldova by SSR markers in order to investigate the genetic relationships among samples along the East-to-West dissemination route of grapevine after the domestication. Based on the descriptive statistics Azerbaijani samples appeared having the highest genetic diversity. PCoA and STRUCTURE analysis revealed three groups: i) Central European group; ii) a group reuniting cultivars coming from Armenia, Georgia and Moldova; iii) the group of Azerbaijani cultivars (94%). The analysis of genetic relationships in our dataset provided evidence of connection among cultivars included in the proles pontica and proles orientalis and geographical origin and human uses as well

    Introduction. The aim of the study was to detect the dependence of the composition of the parietal microflora of the colon on the activity of Helicobacter pylori-associated chronic gastritis and the degree of Helicobacter pylori contamination of the gastric mucosaВведение. Целью работы являлось изучение зависимости состава пристеночной микрофлоры толстого кишечника от активности Helicobacter pylori-ассоциированного хронического гастрита и степени обсемененности Helicobacter pylori слизистой желудк

    The potential risks and impact of the start of the 2015–2016 influenza season in the WHO European Region: a rapid risk assessment

    Background: Countries in the World Health Organization (WHO) European Region are reporting more severe influenza activity in the 2015–2016 season compared to previous seasons. Objectives: To conduct a rapid risk assessment to provide interim information on the severity of the current influenza season. Methods: Using the WHO manual for rapid risk assessment of acute public health events and surveillance data available from Flu News Europe, an assessment of the current influenza season from 28 September 2015 (week 40/2015) up to 31 January 2016 (week 04/2016) was made compared with the four previous seasons. Results: The current influenza season started around week 51/2015 with higher influenza activity reported in Eastern Europe compared to Western Europe. There is a strong predominance of influenza A(H1N1)pdm09 compared to previous seasons, but the virus is antigenically similar to the strain included in the seasonal influenza vaccine. Compared to the 2014/2015 season, there was a rapid increase in the number of severe cases in Eastern European countries with the majority of such cases occurring among adults aged < 65 years. Conclusions: The current influenza season is characterized by an early start in Eastern European countries, with indications of a more severe season. Currently circulating influenza A(H1N1)pdm09 viruses are antigenically similar to those included in the seasonal influenza vaccine, and the vaccine is expected to be effective. Authorities should provide information to the public and health providers about the current influenza season, recommendations for the treatment of severe disease and effective public health measures to prevent influenza transmission
