A system and method of detecting a vascular condition within a body receives vibrations emitted in response to blood flowing through a vascular structure within the body and converts the received vibrations into vibration information. The present invention also concerns diagnostic methods and kits for detection and measurement of anti-angiogenic A peptide activity in biological fluids and tissues. A connecting wiring pattern for connecting the pair of connecting electrodes is provided between the connecting electrodes. Also described is processing the document files into more easily readable documentation, e. The valve may be secured in position utilizing mechanical, magnetic, electromagnetic, pneumatic, electrostatic, or hydraulic approaches. , where the configuration fingerprints for a given node identify selected aspects of the configuration of the node.
