| antibody-coated bacteria test, urinary | Fluorescent antibody technique for visualizing antibody-bacteria complexes in urine. The presence or absence of antibody-coated bacteria in urine correlates with localization of urinary tract infection in the kidney or bladder, respectively. (12 Dec 1998) |

| coated pit | <biology> First stage in the formation of a coated vesicle. (18 Nov 1997) |
| coated pits, cell-membrane | Specialised regions of the cell membrane composed of pits coated with a bristle covering made of the protein clathrin. These pits are the entry route for macromolecules bound by cell surface receptors. The pits are then internalised into the cytoplasm to form the coated vesicles. (12 Dec 1998) |
| coated tongue | A tongue with a whitish layer on its upper surface, composed of epithelial debris, food particles, and bacteria; often an indication of indigestion or of fever. Synonym: furred tongue. (05 Mar 2000) |
| coated vesicle | <cell biology> Vesicle formed as an invagination of the plasma membrane (a coated pit) and that is surrounded by a basket of clathrin. Associated with receptor mediated pinocytosis and receptor recycling. (18 Nov 1997) |
| coated vesicles | Vesicles formed when cell-membrane coated pits (coated pits, cell-membrane) invaginate and pinch off. The outer surface of these vesicles is covered with a lattice-like network of the protein clathrin. Shortly after formation, however, the clathrin coat is removed and the vesicles are referred to as endosomes. (12 Dec 1998) |
| tablets, enteric-coated | Tablets coated with material that delays release of the medication until after they leave the stomach. (12 Dec 1998) |
| enteric-coated | A term designating a special coating applied to tablets or capsules which prevents release and absorption of their contents until they reach the intestines. (18 Nov 1997) |
| enteric coated tablet | An oral dosage form in which a tablet is coated with a material to prevent or minimise dissolution in the stomach but allow dissolution in the small intestine. This type of formulation either protects the stomach from a potentially irritating drug (e.g., aspirin) or protects the drug (e.g., erythromycin) from partial degradation in the acidic environment of the stomach.

| acrosomal cap | A collapsed membranous vesicle that covers the anterior part of the nucleus of the spermatozoon, derived from the acrosomal granule; the carbohydrate-rich substance of the cap is associated with hydrolytic enzymes that aid in sperm penetration of the zona pellucida of the ovum. Synonym: head cap. (05 Mar 2000) |
| apical cap | <radiology> Local pleural thickening at lung apex, ascribed incorrectly to TB, aetiology: non-specific fibrous scarring (most common), Pancoast tumour (12 Dec 1998) |
| bishop's cap | <botany> A plant of the genus Mitella; miterwort. Source: Websters Dictionary (01 Mar 1998) |
| cap | <abbreviation> Catabolite (gene) activator protein. 1. Any anatomical structure that resembles a cap or cover. 2. A protective covering for an incomplete tooth. 3. Colloquialism for restoration of the coronal part of a natural tooth by means of an artificial crown. 4. The nucleotide structure found at the 5' terminus of many eukaryotic messenger RNAs, consisting of a 7-methylguanosine connected, via its 5'-hydroxyl group, by a triphosphate group to the 5'-hydroxyl group of the first nucleoside encoded by the DNA; usually symbolised as m7G5'ppp5'N, where N is nucleoside number 1 in the transcribed mRNA and is often itself methylated; the cap is added posttranscriptionally. (05 Mar 2000) |
| cap binding protein | <molecular biology, protein> Protein (24 kD) with affinity for cap structure at 5' end of mRNA that probably assists, together with other initiation factors, in binding the mRNA to the 40S ribosomal subunit. Translation of mRNA in vitro is faster if it has a cap binding protein. (18 Nov 1997) |
| cap II RNA(nucleoside-2'-)methyltransferase | <enzyme> Converts cap i-terminated mRNA to cap II-terminated mRNA Registry number: EC 2.1.1.- Synonym: cap II methylase (26 Jun 1999) |
