We have developed a model for cloacal exstrophy in the chick embryo using the Cavitron AO 300 CO2 laser. Embryos between 68 and 76 hours of development have been injured caudal to the omphalomesenteric vessels in the region of the tail bud in ovo. This has resulted in the induction of cloacal exstrophy in 5 of 59 chicks that survived ten days after injury.(More)
Immunohistochemical staining for the A, B and H blood group antigens was studied in 61 normal human ureters using monoclonal antibodies with avidin-biotin complex application. Thirty-seven of these were archival material, and 24 were processed prospectively. In 100 per cent of the prospectively processed ureters, A, B and H antigens were demonstrated(More)
In this ongoing study, albumin and prealbumin (transthyretin) changes were compared in 40 patients managed with enteral and (or) parental support with attainment of caloric/protein goals. The concentration of prealbumin in serum changed rapidly and more accurately reflected current nutritional status of these patients than did that of albumin. We determined(More)
Various factors may prolong postoperative recovery and the length of stay (LOS) in the hospital. In a retrospective study of 245 adult patients who had no oral intake for 5 days after major gastrointestinal surgery, we used a correlation matrix to describe the population and determine the effects of the following factors on LOS: malnutrition, complication(More)
We clustered a selected population of patients at Bridgeport (Conn) Hospital into distinct nutritional classes using critical decisions points for the serum concentrations of aspartate aminotransferase activity, cholesterol, total protein, albumin, and prealbumin. The decision points that divided the populations with the highest efficiency were delineated(More)
We show how to make an unsupervised discrimination of disease and nondisease states by measuring information and using newer notions of inductive reason. We also present a new theory of group-based reference values that is based on measuring information uncertainty. We use data on the isoenzymes creatine kinase-MB (CK-MB) and lactate dehydrogenase-1 (LD1)(More)
