The commercially available hemagglutination inhibition (HAI) assay kit for erythropoietin (ESF) was compared with the fetal mouse liver cell (FMLC) bioassay. No correlation was obtained ESF levels determined by both methods in a variety of pathologic sera. The HAI kit showed a great batch variability. Significant immunoreactivity was found in those fractions of a normal human serum and a human ...

In this paper we introduce CoPilot, an active driving aid that enables semiautonomous, cooperative navigation of an electric powered wheelchair (EPW) for automated doorway detection and traversal. The system has been cleanly integrated into a commercially available EPW, and demonstrated with both joystick and head array interfaces. Leveraging the latest in 3D perception systems, we developed bo...

INTRODUCTION With Part 11 of this series, we have reviewed and summarized 110 drugs in formulations with beyonduse dates established and published in the peer reviewed literature. As there is no national/universal standard for these studies, they sometimes differ in the source of ingredients, methods of preparation, storage containers, temperatures, etc. Generally, it is best to use the pure dr...

We present a safe and convenient cross-coupling strategy for the large-scale synthesis of biaryls, commercially important structures often found in biologically active molecules. In contrast to traditional cross-couplings, which require the prior preparation of organometallic reagents, we use a copper catalyst to generate the carbon nucleophiles in situ, via decarboxylation of easily accessible...
