A process of progressive thickening and hardening of the walls of medium-sized and large arteries as a result of fat deposits on their inner lining. Risk factors for atherosclerosis include high levels of “bad” cholesterol, high blood pressure (hypertension), smoking, diabetes and a genetic family history of atherosclerotic disease. Atherosclerosis is responsible for much coronary artery disease (angina and heart attacks) and many strokes.

A fatty deposit in the inner lining (intima) of an artery, resulting from atherosclerosis. Also called an atherosclerotic plaque, an arterial plaque, or a plaque.

The process of forming atheromas, plaques in the inner lining (the intima) of arteries.

A procedure to remove plaque (atheroma) from the inside of a blood vessel. Atherectomy is done most often in major arteries, such as the coronary, carotid, and vertebral arteries, that have experienced the occlusive effects of atherosclerosis. Atherectomy may be accomplished by various means, including angioplasty, laser surgery, conventional surgical incision, or use of a small…

Partial or complete collapse of a previously expanded lung. Secondary atelectasis may occur when full chest expansion is difficult, such as after chest surgery.

Failure of full expansion of the lung at birth, or lung collapse thereafter. Also known as collapsed lung.

Although little known to the general public, the American Type Culture Collection (ATCC) is a key resource for medical research. It is the world’s premier biological culture repository. The ATCC assures medical and other biological scientists a reliable source of over 60,000 authenticated, viable cultures of: Algae & Protozoa Bacteria & Bacteriophages Cultured Cell Lines…
