| promoter regions | <genetics> DNA sequences which are recognised (directly or indirectly) and bound by a DNA-dependent RNA polymerase during the initiation of transcription. Highly conserved sequences within the promoter include the pribnow box in bacteria and the tata box in eukaryotes. (12 Dec 1998) |
|---|---|
| scaffold-associated regions | Sites in DNA that bind topoisomerase II and other scaffold proteins; found in introns. (05 Mar 2000) |
| hypervariable regions | The regions of the immunoglobulin molecule that contain most of the residues involved in the antibody binding site. (05 Mar 2000) |
| terminator regions (genetics) | DNA sequences which signal the termination of transcription. (12 Dec 1998) |
| alar chest | A chest in which the anteroposterior diameter is shorter than the average. Synonym: alar chest, pterygoid chest. (05 Mar 2000) |
| barrel chest | A chest permanently resembling the shape of a barrel, i.e., with increased anteroposterior diameter, roughly equaling the lateral diameter; usually with some degree of kyphosis; seen in cases of emphysema. (05 Mar 2000) |
| gallium uptake with normal chest film | <radiology> Pulmonary drug toxicity, tumour infiltration, sarcoidosis, pneumocystis carinii see: lung: gallium imaging (12 Dec 1998) |
| pain, chest | Chest pain has many cause. One celebrated cause is angina which results from inadequate oxygen supply to the heart muscle due to coronary artery disease or spasm of the coronary arteries. Treatment of angina includes rest, medication, angioplasty, and/or coronary artery bypass surgery. (12 Dec 1998) |
| mass chest X-ray | X-ray screening of large groups of persons for diseases of the lung and heart by means of radiography of the chest. (12 Dec 1998) |
| chest | The anterior wall of the chest or thorax; the breast. See: thorax. Synonym: pectus, phthinoid. Origin: A.S. Cest, a box (05 Mar 2000) |
| chest film | most common X-ray used to detect abnormalities in or within the thoracic cage, such as the lungs, heart, aorta, and the bones of the chest. Extra metallic objects, such as jewelry are removed from the chest and neck areas for a chest X-ray to avoid interference with x-ray penetration and improve accuracy of the interpretation. (12 Dec 1998) |
| chest index | Anteroposterior diameter of the thorax times 100 divided by the transverse diameter of the thorax. Synonym: chest index. (05 Mar 2000) |
| chest leads | Those in which the exploring electrode is on the chest overlying the heart or its vicinity. Synonym: precordial leads, semidirect leads. (05 Mar 2000) |
| chest metastases with pneumothorax | <radiology> Common with metastatic sarcomas: osteosarcoma, rhabdomyosarcoma (12 Dec 1998) |
| chest pain | There are many causes of chest pain. One is angina which results from inadequate oxygen supply to the heart muscle. Angina can be caused by coronary artery disease or spasm of the coronary arteries. Chest pain can also be due to a heart attack (coronary occlusion) and other important diseases. Do not try to ignore chest pain and work (or play) though it. Chest pain is a warning to seek medical attention. (12 Dec 1998) |
