The nature and rate of juvenile hormone (JH) biosynthesis and effects of allatostatins and allatotropin have been investigated in isolated corpora allata (CA) of adults and larvae of the noctuid tomato moth, Lacanobia oleracea. In adult female CA, mean rates of synthesis were relatively constant (10-16 pmol/pr/h) at all times. However, the range of JH synthesis by individual CA of similarly aged insects was quite large (2-30 pmol/pr/h). High performance liquid chromatography (HPLC) separation shows that adult female moth CA synthesise predominantly JH I and JH II. Rates of JH synthesis in vitro are dependent on methionine concentration. Synthetic Manduca sexta allatostatin (Mas-AS) caused a dose-dependent inhibition of JH synthesis by adult female CA but only to a max. of 54%, whilst 10 µM synthetic M. sexta allatotropin caused a 37% stimulation of CA activity. At 1 mM the cockroach allatostatin, Dip-allatostatin-2, had no significant effect on JH synthesis. In larval L. oleracea, rates of JH biosynthesis were very low., Neil Audsley, Robert J.

The article summarises the known information about the life of the politician and significant bibliophile Veit Ulrich Marschall von Ebnet (ca 1565 - ca 1625). Based on the provenance research into Lipník nad Bečvou and Mikulov castle libraries, the National Museum Library and other collections as well as auction catalogues, the paper lists the identified books from his library, describes Marschall’s armorial bindings and other provenance marks, on the basis of which it attempts to characterise the content of this extraordinary library. and Miroslav Koudela, Petr Mašek.
The article draws on the list of separate manuscripts and manuscripts forming part of binders’ volumes coming from the library of the Domažlice Augustinians, a component of the first volume of the Soupis rukopisů Studijní a vědecké knihovny Plzeňského kraje v Plzni [A Compendium of the Manuscripts from the Education and Research Library of the Pilsener Region in Pilsen (Plzeň 2006)]. Since the first and at the same time last description of the library comes from as early as 1950, when the book collection was taken over by the State Education Library in Pilsen, we attempted to study the development of the Augustinian book collection on the basis of indirect sources, such as mainly books of accounts and ownership notes in extant printed books and manuscripts. From the original ca 4,000 volumes, only 272 volumes have been preserved in the Education and Research Library of the Pilsener Region (ERLPR) to this day; two separate manuscripts and 16 manuscripts forming part of binders’ volumes from the 17th-19th centuries have been described in the above-mentioned compendium; two manuscripts that were bound to other manuscripts come from a nearby convent in Pivoň. A noteworthy piece among the literary texts preserved in Prague archives is a manuscript fragment of a Czech play containing a dialogue between two merchants taking place at the Pilsen market, which comes from the second half of the 18th century, or the attempt of the Pivoň Augustinian Bruno Knez to write and even publish the history of his convent from 1753, which may be considered as the first printed monastic monograph from West Bohemia. and Jaromír Linda.
This paper analyses the so-called Chapbooks that were being written or translated on the dawn of the 19th century. The authors tried to educate the ignorant peasants, the targeted readers, through their fetching stories. The work shows facts and deeds that were presented as "right" and "wise". First of all it presents the factual public enlightenment, more specifically the altering appreciation of time. Next, there is an analysis of the way the authors were maintaining the cogency of their work; the paper discusses whether the narrative style of writing is compatible with the didactic intention, and the characteristics of the "rational order of explanation"., Barbora Matiášová., and Obsahuje bibliografické odkazy
