testing of the hemaPEN microsampling device for the quantification of acetaminophen in human blood.

The hemaPEN is a liquid microsampling device for the reproducible collection and storage of blood samples as dried blood spots, for subsequent quantitative analysis. We examined the device's ability to collect accurate and precise blood volumes, at different hematocrit levels, via studies using acetaminophen in human blood. We also investigated the impact of different user training approaches on device performance.

Cell therapies: realizing the potential of this new dimension to medical therapeutics.

Stem cells promise to treat conditions poorly served by conventional therapeutics. Cells from both embryonic and somatic tissues are being used to create cell therapies for genetic, traumatic and degenerative conditions. The current human, healthcare and fiscal costs of these conditions are significant.
