This study evaluated the suitability of delivering patient blood specimens to the blood bank by a hospital pneumatic-tube system. No significant discrepancies were found between duplicate pneumatic-tube and hand-carried specimens in ABO and Rh typing, Du and direct Coombs' testing, rouleaux formation, and antibody screening and identification. There were no(More)
This paper describes an Enzyme Linked Immunosorbent Assay (ELISA) for detecting IgG sensitized erythrocytes utilizing a commercially available anti-human IgG conjugated with alkaline phosphatase. Erythrocyte hemolysis in the assay was minimized by dissolving the p-nitrophenyl phosphate substrate in a carbonate-bicarbonate buffer. Nonspecific absorption of(More)
BACKGROUND Convection enhanced delivery (CED) is emerging as a promising infusion toolto facilitate delivery of therapeutic agents into the brain via mechanically controlled pumps. Infusion protocols and catheter design have an important impact on delivery. CED is a valid alternative for systemic administration of agents in clinical trials for cell and gene(More)
