| captan | <chemical> An industrial fungicide. Pharmacological action: fungicides, industrial. Chemical name: 1H-Isoindole-1,3(2H)-dione, 3a,4,7,7a-tetrahydro-2-((trichloromethyl)thio)- (12 Dec 1998) |
| captopril | <chemical> An orally active inhibitor of angiotensin I-converting enzyme. It reduces elevated blood pressure by inhibiting the renin-angiotensin system and also inhibits pressure responses to exogenous angiotensin I. Pharmacological action: angiotensin-converting enzyme inhibitors, antihypertensive agents. Chemical name: L-Proline, 1-(3-mercapto-2-methyl-1-oxopropyl)-, (S)- (12 Dec 1998) |
| captopril renal scan | <radiology> In a kidney with a lesion in the afferent arteriole (e.g. Atherosclerotic plaque), reflex constriction of the efferent arteriole occurs through angiotensin system thus maintaining renal perfusion. ACE inhibition prevents constriction of efferent arteriole. Therefore, perfusion is decreased to a kidney with afferent lesions and the renal scan to looks WORSE. Bottom line: renal scans appear WORSE with captopril administration if there is a lesion in the afferent arteriole. See: renal artery stenosis (12 Dec 1998) |
| capture | Catching and holding a particle or an electrical impulse originating elsewhere. Origin: L. Capio, pp. -tus, to take, seise Atrial capture, control of the atria for one or more beats after a period of independent beating, as in complete A-V block or in junctional or ventricular ectopic beats or tachycardias by a retrograde impulse. Electron capture, a mode of radioactive disintegration, in which an orbital electron, usually from the K shell, is captured by the nucleus, converting a proton into a neutron with ejection of a neutrino and emission of a gamma ray, and emission of characteristic X-rays as the missing K-shell electron is replaced. Synonym: K capture. (05 Mar 2000) |
| capture-recapture method | Originally, a technique developed by biologists to track wild animal populations; now adapted for epidemiological studies of elusive human populations (e.g., prostitutes, teen runaways, IV drug users).By comparing data from several independent overlapping sample frames, it is possible to adjust for missing cases and to generate estimates of the prevalence of a given condition, for example, AIDS infection.
