|The indirect effect of Tityus discrepans on rabbit pulmonary vasculature.|
Novoa, Eva, et al.
Respiratory physiology & neurobiology, 134: 33-41 (2003) 2003
Serum (IS) was obtained 0.5, 2, 4 or 6 h after inoculating s.c. six rabbits (approximately 2 kg) in each time period with 1 mg/kg of Tityus discrepans (Td) venom; the control was serum obtained from four rabbits 4 h after injecting them 1 ml s.c. of 0.9% NaCl. IS produced a transient (<25 min) rise in pulmonary artery pressure of isolated and perfused rabbit lungs, other lung parameters were not altered. We found that both scorpion venom and IS produced a approximately 50% transient increase of transendothelial electric resistance in cultured tissue human umbilical cord vein. Neither venom nor IS changed the transepithelial electrical resistance of tissue cultured human airway epithelia. The experiments suggest that humoral factors contained in the inoculated serum modify vascular endothelium in a much more effective manner than the venom by itself. These experiments also make it unlikely that vascular endothelium is the source of the humoral factors contained in inflammatory serum.

|Can I use Centrifree with a swinging-bucket rotor?||Yes, but the filtration rate will be only 30-50% of that produced with a fixed-angle rotor at the same g-force.|
|What are the pore and retention characteristics of the YMT 30,000 molecular weight cut-off membrane for Centrifree micropartition device?||The actual pore size is not measured. The membrane is characterized by measuring its retention of known protein markers of specific molecular weights. The given cut-off is a nominal measurement.|
|Does Centrifree have a shelf life?||Yes, one year.|
|What is the maximum spinning speed of the Centrifree unit?||Device limits are measured in g-force, not rpm. The maximum recommended g-force is 2000 × g.|
|How much ultrafiltrate can I expect when using the Centrifree?||For volumes less than 0.5 ml: For a sample volume of 1.0 ml: In 10 minutes: I 1/2 the initial volume approximately 200 µl In 30 minutes: 2/3 to 3/4 the initial volume approximately 450 µl|
|What is the maximum process volume for the Centrifree device?||Maximum volume is 1.0 ml.|
|What molecular weight cut-off does the Centrifree come in?||The Centrifree unit is available in a 30,000 MW cut-off.|
|Can I reuse Centrifree?||No, Centrifree is intended for one-time use only. Multiple use risks membrane failure.|
|What is the minimum process volume for the Centrifree device?||Minimum volume is 0.15 ml.|
|What temperatures can Centrifree be spun at?||Spin devices at 4-50°C. Store at room temperature.|
