arteriography definition: (ar-TEE-ree-AH-gra-fee) A procedure to x-ray arteries. The arteries can be seen because of an injection of a dye that outlines the vessels on an x-ray.
Arteriography definition: The X-ray examination of the arterial blood vessels.
gamma knife definition: Radiation therapy in which high-energy rays are aimed at a tumor from many angles in a single treatment session.
Electron Beam Therapy definition: Radiation therapy using electron beam
tryptophanase activity definition: Catalysis of the reaction: L-tryptophan + H2O = indole + pyruvate + NH3. [EC:4.1.99.1]
tryptophan breakdown, using tryptophanase definition: OBSOLETE. The chemical reactions and pathways resulting in the breakdown of tryptophan, catalyzed by the enzyme tryptophanase (EC:4.1.99.1). [GOC:jl]
magnetoreception, using chemical stimulus definition: The series of events required for an organism to receive a chemical stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. It is believed that organisms such as birds and salamanders use a 'chemical compass': chemical reactions that involve transitions between different spin states can be influenced by magnetic fields and by detecting the different product ratios, these organisms can perceive the direction of the magnetic field. The mechanism by which this is detected is not certain but it may also involve light stimuli. [GOC:ai, http://www.wikipedia.org/Magnetoception]
magnetoreception, using electrical stimulus definition: The series of events required for an organism to receive an electrical stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. Movement in a magnetic field results in an induced electric field, which can be perceived by organisms such as elasmobranch fish. [GOC:ai, http://www.wikipedia.org/Magnetoception]
magnetoreception, using mechanical stimulus definition: The series of events required for an organism to receive a mechanical stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. A magnetic field exerts a torque on a ferromagnetic material (e.g. magnetite) or on a material with diamagnetic anisotropy; organisms that can detect this torque can use it to determine the orientation of the magnetic field.
