| immunofluorescent studies | <technique> A special assay that relies on the production of measurable fluorescent light. An immunofluorescent tagged antibody interacts and binds with an antigen allowing an indirect measurement of its concentration. (27 Sep 1997) |

| intervention studies | Epidemiologic investigations designed to test a hypothesised cause-effect relation by modifying the supposed causal factor(s) in the study population. (12 Dec 1998) |
| intracardiac electrophysiology studies | <cardiology, investigation> A special study that involves the placement of electrodes inside the heart to map the electrical characteristics of the heart. This study is carried out in a specially equipped lab and is similar to a cardiac catheterisation procedure. Electrodes are placed inside the heart via a catheter placed into a vein. The electrodes are positioned near the heart's conduction system and an electrical map of the heart can be determined. This test is often performed in those where a life-threatening cardiac arrhythmia is a problem. The location and characteristics of an arrhythmia can be determined, thus guiding medical management of the problem. Patients with Wolf Parkinson White syndrome or sick sinus syndrome may have this test as part of their evaluation. (27 Sep 1997) |

| epidemiologic studies | Studies designed to examine associations, commonly, hypothesised causal relations. They are usually concerned with identifying or measuring the effects of risk factors or exposures. The common types of analytic study are case-control studies, cohort studies, and cross-sectional studies. (12 Dec 1998) |
| evaluation studies | Studies determining the effectiveness or value of processes, personnel, and equipment, or the material on conducting such studies. For drugs and devices, clinical trials, drug evaluation, and drug screening are available. (12 Dec 1998) |
| twin studies | Methods of detecting genetic aetiology in human traits. The basic premise of twin studies is that monozygotic twins, being formed by the division of a single fertilised ovum, carry identical genes, while dizygotic twins, being formed by the fertilization of two ova by two different spermatozoa, are genetically no more similar than two siblings born after separate pregnancies. (12 Dec 1998) |
| feasibility studies | Studies to determine the advantages or disadvantages, practicability, or capability of accomplishing a projected plan, study, or project. (12 Dec 1998) |
| follow-up studies | Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease. (12 Dec 1998) |
| longitudinal studies | Studies in which variables relating to an individual or group of individuals are assessed over a period of time. (12 Dec 1998) |
| acute African sleeping sickness | A disease of humans caused by Trypanosoma brucei rhodesiense in eastern Africa from Ethiopia and Uganda south to Zimbabwe; it is clinically similar to Gambian trypanosomiasis but of shorter duration and more acute in form; patients suffer repeated episodes of pyrexia, become anaemic, and die commonly from cardiac failure. Synonym: acute African sleeping sickness, acute trypanosomiasis, East African sleeping sickness, East African trypanosomiasis. (05 Mar 2000) |
| african | Of or pertaining to Africa. African hemp, a fibre prerared from the leaves of the Sanseviera Guineensis, a plant found in Africa and India. African marigold, a tropical American plant (Tagetes erecta). African oak or African teak, a timber furnished by Oldfieldia Africana, used in ship building. Origin: L. Africus, Africanus, fr. Afer African. Source: Websters Dictionary (01 Mar 1998) |
| African endomyocardial fibrosis | Fibrosis of the inner layers of the myocardium, often including the endocardium, causing diastolic restriction of the heart; indigenous to East Africa. (05 Mar 2000) |
