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.

Identification of sources of resuspended aerosol particles using statistic methods
Huzlík, J.; Ličbinský, R.; Mikuška, Pavel
2011 - Czech
Parallel collection of aerosol particles in size fractions PM2.5 and PM10 and street dust at the same location was performed in Ostrava and Brno during winter and summer 2009 and 2010. Identification of PM sources including resuspended PM and their contribution to overall PM concentration was done by using receptor modelling methods. Aerosoly ve velikostní frakci PM2.5 a PM10 a pouliční prach byly paralelně vzorkovány v Ostravě a Brně během zimy a léta 2009 a 2010. Zdroje aerosolů, včetně resuspendovaného prachu a jeho příspěvku k celkové koncentraci aerosolů, byly identifikovány pomocí metod receptorového modelování.

Using of divergent flow isoelectric focusing and capillary liquid
Duša, Filip; Moravcová, Dana; Kahle, Vladislav; Šlais, Karel
2011 - Czech
Separation of analytes from complex matrices play important role in their further identification. In this article we propose two-dimensional separation method of bovine serum albumin tryptic peptides. At the first dimension peptides are separated by divergent flow isoelectric focusing followed by reverse-phase liquid chromatography as the second dimension. Due to composition of input mixture it is possible to use autofocusing mode in first dimension. In this mode peptides are focused without addition of carrier ampholytes. Chromatograms from the second dimension were processed into contour map. Acquired data showed good separation efficiency of isoelectric focusing. Autofocusing mode enabled better resolution of peptides with close isoelectric points. Separace analytů z komplexních směsí dnes hraje významnou roli při jejich další identifikaci. V článku je navržena metoda dvoudimenzionální separace směsi tryptických peptidů hovězího sérového albuminu. V první dimenzi jsou peptidy rozděleny isoelektrickou fokusací v rozbíhavém toku a v druhé dimenzi následuje kapalinová chromatografie s reverzní fází. Díky charakteru vstupní směsi je možné u izoelektrické fokusace využít autofokusaci peptidů, tzn. fokusaci bez přídavku nosných amfolytů. Chromatogramy z druhé dimenze byly zpracovány do podoby vrstevnicové mapy. Získaná data ukázala dobrou separační účinnost izoelektrické fokusace a díky autofokusaci bylo možné rozdělit i peptidy s blízkými izoelektrickými body.
