The regional levels' profile of human beta-endorphin (beta h-EP) was studied in the brainstem and the cerebellum of 16 infant victims of "Sudden Infant Death Syndrome" and other death causes. An immunoaffinity chromatography procedure based on a monoclonal antibody directed specifically against the N-terminus of beta-EP was used to extract this peptide from(More)
The number of CT images increased significantly when 16-row multi-detector CT scanners (MDCT) were introduced. The purpose of this study is to quantify the total data management cost of MDCT and to identify cost drivers. An activity-based costing (ABC) method was used to analyze cost drivers in MDCT data management. Changing from 4-row to 16-row CT, mean(More)
A two-site immunoradiometric assay for the highly specific direct quantitation of nonacetylated beta h-EP in crude brain tissue samples has been developed with a detection limit of 10 fmol per well. The assay used two different antibodies with distinct specificities: a polyclonal rabbit anti-beta h-EP antibody binding between the middle portion and the(More)
