| UCLP | unilateral cleft of lip and palate |
| PLDR | potentially lethal damage repair |
| error-prone repair | <molecular biology> A type of DNA repair which occurs when both nucleotides in a base pair are missing, such that it is not possible to maintain accuracy. In general, the repair proteins replace the missing nucleotides randomly. The idea is that bad DNA is better than no DNA at all. (06 Mar 1998) |
|---|---|
| excision repair | <molecular biology> Mechanism for the repair of environmental damage to one strand of DNA (loss of purines due to thermal fluctuations, formation of pyrimidine dimers by UV irradiation). The site of damage is recognised, excised by an endonuclease, the correct sequence is copied from the complementary strand by a polymerase and the ends of this correct sequence are joined to the rest of the strand by a ligase. The term is sometimes restricted to bacterial systems where the polymerase also acts as endonuclease. (11 Nov 1997) |
| anal cleft | The sulcus between the buttocks (nates). Synonym: crena ani, anal cleft, crena clunium, gluteal cleft. (05 Mar 2000) |
| brachial cleft cyst | A cervical cyst arising from the persistence of ectodermal brachial cleft (groove) or endodermal pharyngeal pouches. (27 Sep 1997) |
| branchial cleft cyst | Also called a branchial cyst, this is a cavity that is a remnant from embryologic development present at birth in one side of the neck just in front of the large angulated muscle on either side (the sternocleidomastoid muscle). The cyst may not be recognised until adolescence as it enlarges its oval shape. Sometimes it develops a sinus or drainage pathway to the surface of the skin from which mucus can be expressed. Total surgical excision is the treatment of choice. Recurrence is not expected. (12 Dec 1998) |
| palate, cleft | An opening in the roof of the mouth, due to a failure of the palatal shelves to come fully together from either side of the mouth and fuse during embryonic development. (12 Dec 1998) |
| Rathke's cleft cyst | An intrasellar or suprasellar cyst lined by cuboidal epithelium derived from remnants of Rathke's pouch. (05 Mar 2000) |
| gingival cleft | A fissure associated with pocket formation and lined by mixed gingival and pocket epithelium. (05 Mar 2000) |
| visceral cleft | Any cleft between two branchial (visceral) arches in the embryo. (05 Mar 2000) |
| median maxillary anterior alveolar cleft | <anatomy> An asymptomatic midline defect of the maxillary anterior ridge; the result of a failure of fusion or development of the lateral halves of the palate. (05 Mar 2000) |
| gluteal cleft | The sulcus between the buttocks (nates). Synonym: crena ani, anal cleft, crena clunium, gluteal cleft. (05 Mar 2000) |
| residual cleft | The remnants of the pituitary diverticulum that occur between the pars distalis and pars intermedia; a distinct lumen is present in some animals, but, in humans, is present only during prenatal development and sometimes in young children. Synonym: residual lumen. (05 Mar 2000) |
| cholesterol cleft | A space caused by the dissolving out of cholesterol crystals in sections of tissue embedded in paraffin. (05 Mar 2000) |
| cleft | A fissure. (05 Mar 2000) |
| cleft hand | A congenital deformity in which the division between the fingers, especially between the third and fourth, extends into the metacarpal region. See: lobster-claw deformity. Synonym: main fourchee, split hand. (05 Mar 2000) |
