caps definition

<chemical>

Trans-8-methyl-n-vanillyl-6-nonenamide. Cytotoxic alkaloid from various species of capsicum (pepper, paprika), of the solanaceae; causes pain, irritation and inflammation;, due to substance p depletion from sensory (afferent) nerve fibres; used mainly to study the physiology of pain and in the form of capsicum as a counterirritant and gastrointestinal stimulant.

Chemical name: 6-Nonenamide, N-((4-hydroxy-3-methoxyphenyl)methyl)-8-methyl-, (E)-

(12 Dec 1998)

<enzyme>

<cell biology> Catalyses the conversion of antheraxanthin and violaxanthin to capsanthin and capsorubin, respectively; isolated from capsicum annuum; genbank x77289

Registry number: EC 1.-

Synonyms: ccs gene product

(26 Jun 1999)

A yellowish red oleoresin containing the active principle of capsicum.

(05 Mar 2000)

A genus of solanaceous shrubs that yield capsaicin. Several varieties have sweet or pungent edible fruits that are used as vegetables when fresh and spices when the pods are dried.

(12 Dec 1998)

A protein coat that covers the nucleoprotein core or nucleic acid of a virion. Commonly shows icosahedral symmetry and may itself be enclosed in an envelope (as in the Togaviridae). The capsid is built up of subunits (some integer multiple of 60, the number required to give strict icosahedral symmetry) that self assemble in a pattern typical of a particular virus. The subunits are often packed, in smaller capsids, into 5 or 6 membered rings (pentamers or hexamers) that constitute the morphological unit (capsomere). The packing of subunits is not perfectly symmetrical in most cases and some units may have strained interactions and are said to have quasi equivalence of bonding to adjacent units.

(05 Mar 2000)

A cataract in which the opacity affects the capsule only.

(05 Mar 2000)

Preferred term: glisson's cirrhosis

<procedure>

A reconstructive procedure for correction of uteropelvic obstruction, whereby a flap of renal capsule is swung down from the renal hilus to enlarge an obstructed intrarenal pelvis and upper ureter; used to correct situations involving loss of renal pelvic tissue which preclude the use of renal pelvis for the reconstruction.

(05 Mar 2000)

Glaucoma occurring in association with widespread deposition of cellular organelles on the lens capsule, ocular blood vessels, iris, and ciliary body.

Synonyms: Bowman's space, filtration space.

(05 Mar 2000)

Enclosure in a capsule.

(05 Mar 2000)

In the embryo, the vascular mesenchymal capsule that invests the lens of the eye; the vessels of the dorsal part of the capsule are branches of the hyaloid artery; those of the ventral part are derived from the anterior ciliary arteries; normally all the vessels are atrophied by the end of the eighth month of intrauterine life.

(05 Mar 2000)

<microbiology> Thick gel like material attached to the wall of gram-positive or gram-negative bacteria, giving colonies a smooth appearance. May contribute to pathogenicity by inhibiting phagocytosis. Mostly composed of very hydrophilic acidic polysaccharide, but considerable diversity exists.

<pathology> Cellular response in invertebrate animals to a foreign body too large to be phagocytosed. A multicellular aggregate of haemocytes or coelomocytes isolates the foreign object. In some insects the capsule is apparently acellular and composed of melanin.
