coronary

 [kor´ah-nar-e]
encircling in the manner of a crown; said of anatomical structures such as vessels, ligaments, or nerves.
coronary arteries two large arteries that branch from the ascending aorta and supply all of the heart muscle with blood (see also table of arteries).
 A view of the coronary arterial system. The arteries serving the posterior aspect of the myocardium are shown here in a lighter shade.
coronary artery disease (CAD) atherosclerosis of the coronary arteries, which may cause angina pectoris, myocardial infarction, and sudden death. Both genetically determined and avoidable risk factors contribute to the disease; they include hypercholesterolemia, hypertension, smoking, diabetes mellitus, and low levels of high density lipoproteins (HDL).
coronary heart disease (CHD) ischemic heart disease.
coronary occlusion the occlusion, or closing off, of a coronary artery, usually caused by a narrowing of the lumen of the blood vessels by the plaques of atherosclerosis. Sometimes a plaque may rupture and release vasoactive or thrombogenic substances that lead to clot formation. If there is adequate collateral circulation to the heart muscle at the time of the occlusion, there may be little or no damage to the myocardial cells. When occlusion is complete, however, with no blood being supplied to an area of the myocardium, myocardial infarction results.

A gene on chromosome 2p22-p21 that encodes a trifuctional enzyme linked to the activities of the first 3 enzymes—carbamoylphosphate synthetase, aspartate transcarbamoylase and dihydroorotase—in the 6-step pathway of pyrimidine biosynthesis. It is regulated by the mitogen-activated protein kinase (MAPK) cascade, indicating a link between MAPK cascade activation and synthesis of pyrimidine nucleotides.

For years, engineering students were forced to sketch their ideas in two dimensions, first on paper and then on the computer with the first generation of 2D CAD software.
More than 20 years ago, in the days when 2D CAD was getting pretty sophisticated and 3D CAD was coming along too, though a bit limited on representation of real properties such as surfaces, textures and internals, the technology for designing products split off from the technology for designing buildings and structures.
"A limitation of 2D CAD is that it doesn't readily allow for bend radiuses so that getting it right often required drawing the spec a second time," says Gadberry.
Designed to streamline the documentation process for engineers, Presenter and Presenter Pro software creates interactive 3D documents directly from 3D and 2D CAD files.
