Quantitative assays for measuring the binding of xenogeneic antiserum to dispersed cell suspensions are described. Cells were incubated with unlabeled xenogeneic antiserum and the antibody bound measured indirectly by a second binding step with 125I-labeled anti-immunoglobulin antibody. This indirect radioactive binding assay was calibrated by measuring,(More)
PURPOSE To determine the specificity and prognostic significance of computed tomography (CT) of the chest in pediatric Wilms' tumor. PATIENTS AND METHODS Patients treated for newly diagnosed Wilms' tumor at St Jude Children's Research Hospital between December 1978 and July 1995 were included in the study if an initial chest radiograph and CT were(More)
Cellular topography within the highly polarized surface epithelia can be used to identify the location of the stem cells. In some instances, this can be quite precise and allows the characteristics of stem cells to be studied. Our current knowledge of the stem cell population in murine epidermis and small intestinal crypts is reviewed. In the epidermis, the(More)
One hundred twenty patients from each of 6 family practices were surveyed to determine the prevalence of symptom-based psychiatric illness (emotional distress) in family practice. Assessments of presence or absence of emotional distress and the severity of this distress were made using ratings made by the treating physician and by the patient. Nineteen(More)
The electrical activity of caudate neurones was recorded with intracellular electrodes in halothane anaesthetized cats. Agonists and antagonists of excitatory amino acid receptors were applied by micro-ionophoresis and their effects on membrane- and action potentials and on cortically evoked synaptic potentials evaluated. The agonists, L-aspartate (asp),(More)
Antibodies to parvalbumin label intensely a small number of non-overlapping fibre systems in embryonic rat brain. All are in hindbrain--the oculomotor and trochlear motor fibres, the acoustic and vestibular fibres of the VIIIth nerve, and an unidentified group of fibres which ascend under the dorsal surface in caudal medulla. Of these, the vestibular fibres(More)
The identification and physical isolation of epithelial stem cells is critical to our understanding of their growth regulation during homeostasis, wound healing, and carcinogenesis. These stem cells remain poorly characterized because of the absence of specific molecular markers that permit us to distinguish them from their progeny, the transit amplifying(More)
BACKGROUND Mechanical circulatory assist industries have developed ventricular assist devices (VAD) for short-, intermediate-, and long-term use. The purpose of this report is to describe the progress made with the ABIOMED Biventricular System (BVS) 5000 (ABIOMED, Inc, Danvers, MA) short-term VAD. METHODS From June 1994 through August 2000, all(More)
