Does cryopreservation reduce the concentration of detectable bacteria in contaminated peripheral blood progenitor cell products?
The cryopreservation reduces the concentration of detectable bacteria in contaminated PBPCPs. Especially in sterility testing of PBPCPs with low bacterial contamination, this phenomenon could lead to false-negative results with severe clinical consequences.
Visual brain perfusion patterns correlate with the extent, severity, and short-term outcome of hemispheric stroke. HMPAO SPECT may improve the prognostic value of clinical examination if performed during the first 72 hours of stroke.
