Cíl studie: Výsledek každé analýzy DNA je do značné míry závislý na typu biologického materiálu použitého pro extrakci nukleových kyselin. Cílem naší studie je porovnat vlastnosti DNA extraktů získaných dvěma různými izolačními postupy z buněk bukální sliznice, močového sedimentu, nehtů, vlasových kořínků a periferních krevních buněk. Materiál a metody: Biologické vzorky byly získány od 24 dobrovolníků s mediánem věku 31 let (25–54 let). Izolace DNA byla provedena fenol-chloroformovou extrakcí a pomocí separačních mikrokolonek (Qiagen). Eluční objem byl v obou případech 50 μl. Extrakty byly charakterizovány spektrofotometricky, fluorimetricky, elektroforeticky a z hlediska účinnosti následné PCR amplifikace. Výsledky: Nejvyšší koncentrace DNA obsahovaly extrakty z buněk periferní krve a bukální sliznice; nejnižší koncentrace DNA byly izolovány z vlasových kořínků. Všechny typy extraktů měly uspokojivou čistotu (mediány v rozmezí 1,7–1,9). Podíl nefragmentované DNA ve vzorcích získaných mikrokolonkovou metodou byl téměř dvojnásobný v porovnání s fenolovou extrakcí. Procentuální zastoupení nefragmentovaných molekul klesal podle biologického zdroje v následující řadě: krev (73,3 %) > bukální sliznice (63,5 %) > močový sediment (31,3 %) > nehty (25,3 %) > vlasy (20,4 %). Amplifikační účinnost u extraktů z periferní krve, bukálního stěru a močového sedimentu byla vyšší než u extraktů z nehtů a vlasů. Závěr: Všechny analyzované extrakty pocházející z krevních buněk, bukální sliznice, močového sedimentu, nehtů a vlasů poskytly dostatek DNA molekul k provedení molekulárně biologických vyšetření. Nejvhodnějšími materiály byly krevní buňky a buňky bukální sliznice. Z nich připravené extrakty měly nejvyšší koncentraci a čistotu DNA bez ohledu na použitou izolační metodu, nejnižší podíl degradované DNA a nejvyšší účinnost amplifikace krátkých i dlouhých amplikonů., Objective: Results of DNA testing depend in many cases on the type of biological material used for extraction of nucleic acids. The aim of the study is to compare properties of DNA extracts prepared using two different isolation procedures from buccal cells, urine sediment, nails, hair roots, and peripheral blood cells. Material and Methods: Biological material was collected from 24 volunteers at median age of 31 years (range 25–54 years). Phenol–chloroform extraction and spin microcolumn extraction method (Qiagen) were used for DNA isolation. In both the procedures, the elution volume was 50 μl. The extracts were characterized optically (UV spectrophotometric and fluorimetric analyses), electrophoretically, and by PCR amplification efficiency. Results: The highest DNA concentrations were found in extracts from peripheral blood and buccal cells; the lowest DNA concentrations were in hair extracts. All types of the extracts had acceptable purity (medians 1.7–1.9). The content of nonfragmented DNA molecules in the microcolumns extracts was almost twofold higher in comparison to the phenol ones. The percentages of non-fragmented DNA decreased as follows: blood (73.3 %) > buccal cells (63.5 %) > urine sediment (31.3 %) > nails (25.3 %) > hair roots (20.4 %). The amplification efficiency in the peripheral blood, buccal swab, and urine extracts was significantly higher than in the nail and hair extracts. Conclusion: All analyzed DNA extracts received from blood, buccal cells, urine sediment, nails, and hair roots provided a sufficient number of integral DNA molecules for following DNA testing. The best quality of DNA was found in extracts from blood and buccal cells (high concentrations and purity, low degree of fragmentation, and high efficiency of amplification for either short or long PCR amplicons)., Beránek M., Hegerová J., Drastíková M., and Literatura 25
The author examines the clientele of the Bratislava booksellers Anton Löwe and Philip Ulrich Mahler in the context of the Hungarian book trade from 1770 to 1800. By analysing the extant correspondence of Michal Institoris Mošovský, a protestant pastor in Bratislava, she was able to partially identify one segment of their customer base - protestant clergymen. For many years these members of the petty intelligentsia purchased from the Bratislava booksellers, in particular imported works by the German pietists and Enlightenment theologians. The author also investigated the social and geographical limits of the distribution process, some of the contact and distribution networks, and the identity of key figures., Petronela Križanová., and Obsahuje bibliografické odkazy
This study deals with the relationship of Prince Joseph Adam von Schwarzenberg to music and theatre and with the way in which his theatrical preferences revealed themselves in the repertoire of his private castle theatre in Cesky Krumlov from 1766 until 1768. Through a careful study of the extant sources (correspondence, libretti, scores and parts, accounting books etc.), the author has managed to specify the reasons for the precipitous renovation of the castle theatre in late 1765 and early 66 and to determine what specific dramatic works were performed there. Among other things, she has succeeded in compiling the entire list of performances planned for the fourteen-day wedding celebration in the summer of 1768. The author furthermore focuses on information about the musicians who were then in the princes services and also about commissioned musical instruments and musical scores and parts., Helena Kazárová., Obsahuje seznam literatury, and Anglické resumé na s. 45.
This article deals with naming practices among the Czechs who lived in the first half of 20th century in two Bulgarian villages - Vojvodovo and Belinci. It is based on fieldwork carried out among the people who migrated in 1950 from Bulgaria and settled in several towns and villages in South Moravia (region of Mikulov and Valtice), and their descendants. Naming practices of the Bulgarian Czechs are analyzed in relation to naming strategies of the Bulgarians in the given period, and it is argued that the role that was fulfilled by surnames among the Czechs was fulfilled by first names among the Bulgarians. Relationship between the naming strategies and ideas about kinship and gender are discussed further.
