Magnetic flux trapped on the surface of superconducting rotors of the Gravity Probe B ~GP-B! experiment produces some signal in the superconducting quantum interference device readout. For the needs of GP-B error analysis and simulation of data reduction, this signal is calculated and analyzed in this article. We first solve a magnetostatic problem for a point source on the surface of a sphere,...

Starting 90 years ago with a clinical description by Glanzmann of a bleeding disorder associated with a defect in platelet function, technologic advances helped investigators identify the defect as a mutation(s) in the integrin family receptor, IIb 3, which has the capacity to bind fibrinogen (and other ligands) and support platelet-platelet interactions (aggregation). The receptor’s activation...

La thrombasthenie de Glanzmann est une anomalie plaquettaire qualitative, à transmission autosomale récessive, due à un déficit en glycoprotéine IIb/IIIa (GPIIb/IIIa), avec un défaut d’agrégation plaquettaire. Il en résulte une perturbation de l’hémostase primaire, à l’origine d’hémorragie plus ou mois importantes. Nous rapportons l’observation de N.A, âgée de 32 ans, suivie depuis l’enfance po...

BACKGROUND Consultation skills are essential for general practice. Tools for measuring consultation skills in everyday practice are not well developed AIM To examine and develop the content validity of the MAAS History-taking and Advice Checklist GP (MAAS-GP) tool which is used in The Netherlands for testing consultation skills, with simulated patients in United Kingdom general practice from ...
