| Von Willebrand disease | <disease, haematology> A hereditary platelet disorder caused by defective or deficient Von Willebrand factor, a protein involved in normal blood clotting, that reduces adhesion to collagen but not aggregation. Both bleeding time and coagulation are increased. Factor VIII levels are secondarily reduced. Symptoms include nosebleeds, bleeding gums, heavy menstrual bleeding, bruising and skin rashes. Inheritance: autosomal dominant. (30 Sep 1997) |

| vortex | Origin: L. Vortex, vertex, -icis, fr. Vortere, vertere, to turn. See Vertex. 1. A mass of fluid, especially of a liquid, having a whirling or circular motion tending to form a cavity or vacuum in the center of the circle, and to draw in towards the center bodies subject to its action; the form assumed by a fluid in such motion; a whirlpool; an eddy. 2. A supposed collection of particles of very subtile matter, endowed with a rapid rotary motion around an axis which was also the axis of a sun or a planet. Descartes attempted to account for the formation of the universe, and the movements of the bodies composing it, by a theory of vortices. 3. <zoology> Any one of numerous species of small Turbellaria belonging to Vortex and allied genera. <chemistry> Vortex atom, a hypothetical ring-shaped mass of elementary matter in continuous vortical motion. It is conveniently regarded in certain mathematical speculations as the typical form and structure of the chemical atom. Vortex wheel, a kind of turbine. Source: Websters Dictionary (01 Mar 1998) |
