The monophyly of the subgenus Leptempis Collin of the genus Empis L. is established on the basis of a male hypopygial character, and the possibility of a close relationship between the subgenera Leptempis Collin, Planempis Frey and Kritempis Collin is discussed. Seven new species belonging to Empis (Leptempis) rustica-group are described from France, Germany, Greece and Spain: E. (L.) abdominalis sp. n., E. (L.) lamellata sp. n., E. (L.) multispina sp. n., E. (L.) pandellei sp. n., E. (L.) lamellimmanis sp. n., E. (L.) sinuosa sp. n. and E. (L.) trunca sp. n. A key to the E. (L.) rustica-group is presented., Christophe Daugeron, and Lit
Myotropic neuropeptides were isolated from the retrocerebral complex of the stick insect, Carausius morosus, by using three HPLC steps. Bioactivity during purification was measured by heterologous bioassays monitoring the contractions of the hyperneural muscle and hindgut of the American cockroach. Additionally, fractions not active in these bioassays were tested in a homologous bioassay evoking contractions of the hindgut of C. morosus. Peptide sequence analysis and mass spectrometry yielded the following structures: Pro-Phe-Cys-Asn-Ala-Phe-Thr-Gly-Cys-NH2 (CCAP), pGlu-Thr-Phe-Gln-Tyr-Ser-His-Gly-Trp-Thr-Asn-NH2 (His7-corazonin) and Asp-Glu-Gly-Gly-Thr-Gln-Tyr-Thr-Pro-Arg-Leu-NH2 (Cam-PK-1). These neuropeptides are the first myotropins isolated from C. morosus. The most bioactive compound in the homologous bioassay, the C. morosus-hindgut assay, was CCAP., Reinhard Predel, Roland Kellner, Gerd Gäde, and Lit
Teploty vzduchu okolo 100 °C, erupce sopek, blesky, dopady masivních asteroidů, silné ultrafialové zářeni. Jak v takovém pekle na Zemi před čtyřmi miliardam ilet mohl vzniknou život? Otazek je více než odpovědí a pátrání po původu živoat zůstává dobrodružnou disciplínou, v níž spolu soupeří zastánci různých teorii. and Luděk Svoboda, Stanislava Kyselová.

The study is based on an analysis of content and themes of the correspondence of the wellknown Enlightenment Era "provincial intellectual", a bank clerk from Čáslav Jan Ferdinand Opiz (1741-1812), with a country priest from the highlands on the border of Bohemia and Moravia, Karel Killar (1745-1806). Their correspondence - in most part hitherto unstudied - is deposited in the National Museum in Prague. It consists of more than 300 letters, written over a long period of 16 years (1793-1806), and it is fascinating for several reasons: it is conducted in French, which represents one of the very rare testimonies of a good knowledge of French in some members of other classes than the nobility in the 18th and 19th centuries; in this case, the use of French can be read as an implicit adherence to (French) Enlightenment, and perhaps even to the principles of the French Revolution. And it is the Enlightenment, the French Revolution and Napoleonic Wars around which the entire correspondence revolves. Thanks to this we may not only form a deeper and more nuanced insight into Opitz, a wellknown sympathizer of the French Revolution, but also into the lesser known figure of Killar, a man of universal education and an Enlightenment era priest of Josephine stamp, who tried to integrate both the Enlightenment and the French Revolution within his firm Christian (Catholic) worldview., Daniela Tinková., and Obsahuje bibliografické odkazy
