BACKGROUND The aim of this study was the ex vivo expansion of Umbilical Cord Blood hematopoietic stem cells on biocompatible nanofiber scaffolds. MATERIALS AND METHODS CD133+ hematopoietic stem cells were separated from umbilical cord blood using MidiMacs (positive selection) system by means of monocolonal antibody CD133 (microbeads); subsequently, flowcytometry method was done to assess the ...

Neuropeptides are subject of increased interest for their alleged role in various central nervous system processes. However, in vivo assessment of these compounds is complicated because of the generally low concentrations in the brain and the neuropeptides susceptibility to proteolytic degradation. This explains why so few microdialysis studies on neuropeptides have been published in the past. ...

In the recent years, the complexationultrafiltration technique has been shown to be a promising technique for removal of heavy metals in solution. In this study, a polymerenhanced ultrafiltration process has been investigated for removal of toxic heavy metals such as Cu(II), Ni(II), and Cr(III) from synthetic wastewater solutions. Carboxy methyl cellulose as a water-soluble polymer was used for...

Für die Schönung/Klarfiltration von Apfelsäften wird seit vielen Jahren eine Ultrafiltrations-Polyethersulfon-Rohrmembran erfolgreich verwendet. Diese findet bei der Filtration dunkler Fruchtsäfte keine Anwendung, da teilweise auch charakteristische Farbstoffe zurückgehalten werden. Um diesen Markt erschließen zu können, soll Rohrhülsenmembran auf PVDF-Basis entwickelt werden, dunkle Säfte nich...

The effect of different membrane filters on the bioactivity of tomato root exudates was tested in an in vitro assay addressing the germination of microconidia of the soil-borne fungus Fusarium oxysporum f. sp. lycopersici. Membrane filtration of unsterile root exudates with filters of different membrane materials and filter brands resulted in an increased microconidia germination. This effect v...
