| thin film | <radiobiology> Plasmas are often used to deposit thin-film coatings on various materials. (09 Oct 1997) |
| thin layer chromatography | <technique> Chromatography using a thin layer of powdered medium on an inert sheet to support the stationary phase. Faster than paper chromatography, gives higher resolution and requires smaller samples. (18 Nov 1997) |
| thin-layer chromatography | Chromatography through a thin layer of cellulose or similar inert material supported on a glass or plastic plate. (05 Mar 2000) |
| thin-layer electrophoresis | Electrophoretic migrations (separations) through a thin layer of inert material, such as cellulose, supported on a glass or plastic plate. (05 Mar 2000) |
| thin-layer immunoassay | A method for detection of antigen-antibody reactions, applicable to detection of either antigen or antibody, based on the fact that either reactant, when added to a polystyrene surface (such as a well in a polystyrene plate) is adsorbed as a thin layer and acts as an immunosorbent capable of binding with the second reactant. (05 Mar 2000) |
| thin section | A section of tissue for electron microscopic examination; the specimen is fixed, typically in glutaraldehyde and/or in osmium tetroxide, embedded in a plastic resin, and sectioned at less than 0.1 um in thickness with a glass or diamond knife in an ultramicrotome. (05 Mar 2000) |
| thin-skinned | Having a thin skin; hence, sensitive; irritable. Source: Websters Dictionary (01 Mar 1998) |
| adrenal cyst | <radiology> Same characteristics as renal cysts, but less common, thick wall, septations, calcifications suggests pseudocyst (12 Dec 1998) |
| adventitious cyst | 1. An accumulation of fluid in a cystlike loculus, but without an epithelial or other membranous lining. Synonym: adventitious cyst, false cyst. 2. A cyst whose wall is formed by a host cell and not by a parasite. 3. A mass of 50 or more Toxoplasma bradyzoites, found within a host cell, frequently in the brain; formerly called a pseudocyst, but now considered a true cyst enclosed in its own membrane within the host cell that may rupture to release particles that form new cysts, and apparently is infective to another vertebrate host. See: bradyzoite. Origin: pseudo-+ G. Kystis, bladder (05 Mar 2000) |
| allantoic cyst | Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterised by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus. (12 Dec 1998) |
| alveolar hydatid cyst | A hydatid cyst of a multiloculate type, usually in the liver, caused by Echinococcus multilocularis, adults of which are in foxes; larvae (alveolar hydatid) are found chiefly in microtine rodents, but also among humans such as trappers and others handling pelts of infected foxes and other carnivores; growth is by exogenous budding and is not limited by an outer laminated membrane as in the hydatid cyst from E. Granulosus; necrosis, cavitation, contiguous spread, and death usually ensue. Synonym: multilocular hydatid cyst, multiloculate hydatid cyst. (05 Mar 2000) |
| aneurysmal bone cyst | <radiology> ABC, 10 - 30 yrs, 75% before skeletal maturity, sites: long bones; also, flat bones Findings: metaphyseal if unfused, metaepiphyseal after fusion, lytic, expansile, thin, continuous rim, thin internal bony strands (12 Dec 1998) |
