The cell culture became an invaluable tool for studying cell behaviour, development, function, gene expression, toxicity of compounds and efficacy of novel drugs. Although most results were obtained from cell cultivation in two-dimensional (2D) systems, in which cells are grown in a monolayer, three-dimensional (3D) cultures are more promising as they correspond closely to the native arrangement of cells in living tissues. In our study, we focused on three types of 3D in vitro systems used for cultivation of one cell type. Cell morphology, their spatial distribution inside of resulting multicellular structures and changes in time were analysed with histological examination of samples harvested at different time periods. In multilayered cultures of WRL 68 hepatocytes grown on semipermeable membranes and non-passaged neurospheres generated by proliferation of neural progenitor cells, the cells were tightly apposed, showed features of cell differentiation but also cell death that was observable in short-term cultures. Biogenic scaffolds composed of extracellular matrix of the murine tibial anterior muscle were colonized with C2C12 myoblasts in vitro. The recellularized scaffolds did not reach high cell densities comparable with the former systems but supported well cell anchorage and migration without any signs of cell regression. and H.

Rilmenidin je antihypertenzivum ze skupiny agonistů imidazolinových receptorů. Podstatou jeho mechanizmu účinku je výrazné snížení kardiální a renální sympatické baroreflexní odpovědi na úrovni I1-imidazolinových receptorů s následným snížením aktivity sympatiku. Účinnost a snášenlivost rilmenidinu byly prokázány v randomizovaných srovnávacích studiích u starších pacientů, hypertoniků s diabetem a metabolickým syndromem i u pacientů s renálním selháním. Indikací pro podávání rilmenidinu je léčba esenciální hypertenze u dospělých pacientů všech věkových kategorií. Doporučená dávka je 1 mg denně (ráno)., Rilmenidine is an antihypertensive from the group of imidazoline receptor agonists. The basis of its mechanism of action is significant reduction of cardiac and renal sympathetic baroreflex response at the level of I1-imidazoline receptors with subsequent reduction of the sympathetic activity. The effectiveness and tolerability of rilmenidine were proved in randomized comparative studies in elderly patients, patients suffering from hypertension together with diabetes and metabolic syndrome, and in patients with renal failure. The indication for administering rilmenidine is treatment of essential hypertension in adult patients of all age groups. The recommended dose is 1 mg a day (in the morning)., and Souček M.
Název Centrum pro výzkum věřejného mínění nebo jeho zkratku CVVM zná asi každý. Přinejmenším z televizního zpravodajství týkajícího se stranických preferencí, volebních modelů či předvolebních průzkumů. Málokdo však ví, že jed o pracoviště Sociologického ústavu AV ČR. Ještě překvapivější bude asi zjištění, že v CVVM pracuje pouhých 15 lidí. and Luděk Svoboda.
This study introduces an emblematic scheme within the stucco decoration of the Palace Chapel in Červené Poříčí. The given emblematic sheme glorifies the Most Sacred Heart of Jesus. It was inspired by the emblem book of the Bavarian theologian Anton Ginther, which was published in 1706. The article tries to place the programme of the decoration into the context of Middle European evolution of the devotion to the Most Sacred Heart of Jesus - a cult that was very popular at the time. Finally, the article places the decorative scheme into political and historical context and discusses the role its patron played in determining the decoration’s commission and execution., Daniela Štěrbová., and Obsahuje bibliografické odkazy
