Unique exposure system for the whole body inhalation experiments with small animals
Večeřa, Zbyněk; Mikuška, Pavel; Dočekal, Bohumil; Vojta, Šimon; Míšek, Ivan; Moravec, Pavel; Smolík, Jiří
2011 - English
The especially inhalation chamber is constructed for chronic exposure studies of small animals to nanoparticles under strictly controlled conditions in frame of project „Study of transport of inhalated nano-sized particles (Pb, Cd) and their allocation in organs“. The inhalation chamber builds from a glass and stainless steel and makes possible long-term inhalation procedures (up to 60 days, 24 hours/day) with up to four discrete groups of mice population (up to 60 individuals each) or of rats population (up to 20 individuals each) under controlled illumination, temperature, relative humidity, doses (0.5 x 106 - 5 x 106 particles/cm3) and size (10-60 nm) of nano-sized particles which are synthesized via aerosol route in a hot wall tube flow reactor using metal organic precursors.

Seasonal variation in chemical composition of submicron urban aerosol in Brno
Mikuška, Pavel; Křůmal, Kamil; Večeřa, Zbyněk; Vojtěšek, Martin
2011 - English
Submicron aerosol particles in the size fraction PM1 collected in Brno in winter and summer of 2009 were analysed for both selected inorganic (ions, metals) and organic components (PAHs, hopanes and steranes, monosaccharide anhydrides, monocarboxylic acids). Special attention was paid to analysis of organic molecular markers to identify the major emission sources of aerosols.

Immunofluorescent labeling of tissues and free cells via QD-protein conjugates
Lišková, Marcela; Voráčová, Ivona; Hezinová, Věra; Klepárník, Karel; Foret, František
2011 - English
Preparation of quantum dots and using their QD-protein conjugates in immunofluorescent labeling of cells and tissues. For conjugation was used method viaEDC/sulfo-NHS zero-length cross-linkers. We linked QD with annexin V, anti-CD3 and anti-PCNA. We labeled T-lymphocytes, apoptotic lymphocyte, mouse duodenum tissue and tumor tissue.

Arsenic speciation analysis by hydride generation – cryotrapping – atomic fluorescence spectrometry with flame-in-gas-shield atomizer
Svoboda, Milan; Musil, Stanislav; Matoušek, Tomáš; Rychlovský, P.; Dědina, Jiří
2010 - English
The main target of this work was further improvement of detection limits in the method of arsenic speciation analysis of tri- and pentavalent human metabolites in complex biological matrices. The method combines selective hydride generation with preconcentration and subsequent separation of substituted arsines in a cryogenic trap.
