After 1918, the newly created Czechoslovakian Republic offered a helping hand to many thousands of Ukrainians who had fled their native country, which had been occupied by the Soviet Union. The young Ukrainian intelligentsia studied at Czech secondary schools and universities, in Prague at the Mikhail Drahomanov Pedagogical Institute (1923–1933), and in Řevnice, near Prague, at a Ukrainian Secondary School. Several dozens of Ukrainian students studied, supported by the Czechoslovakian state, at Prague Conservatoire. Special attention is paid here to the students of composition (including Mykola Kolessa, Hryhory Dyachenko, Zenovy Lysko, Nestor Nyjankivsky and Roman Simovych).
The aim of the work is to analyze the peculiarities of Ukrainian secondary education abroad in the 1920s and 1930s on the example of the Ukrainian secondary school („Ukrainian Gymnasium“) in Czechoslovakia. The analysis of features of the organization, methodological bases of educational work of the Gymnasium in Prague as a part of the general cultural and educational activity of the Ukrainian interwar emigration is carried out.
Retroviry jsou jednoduché RNA viry, které se vyznačují schopností přepsat svou RNA do dvouřetězcové DNA a tu stabilně začlenit do genetické informace hostitelské buňky. Tato jejich vlastnost stojí za latencí viru HIV, která v současnosti představuje hlavní překážku v úspěšné léčbě HIV pozitivních pacientů. Na druhou stranu lze této jejich vlastnosti využít pro přenos genetické informace za účelem léčby četných chorob s využitím přístupů genové terapie. Pro tyto účely je však potřeba retroviry vybavit sekvencemi, které zajistí jejich stabilní aktivitu a ochrání je před umlčením., Retroviruses are simple RNA viruses, which exhibit an ability to convert their RNA to double-stranded DNA and introduce it into the host cell genome. This ability stands behind the HIV latency phenomenon - a major obstacle to successful therapy. On the other hand, this capability can be utilized for the transfer of genetic information in order to cure various diseases using gene therapy approaches. To achieve successful therapy, the retroviruses need to be equipped with sequences protecting them from silencing, thus stabilizing their activity., and Filip Šenigl.
