| RNA, transfer, ser | A transfer RNA which is specific for carrying serine to sites on the ribosomes in preparation for protein synthesis. (12 Dec 1998) |

| SER | <cell biology> An internal membrane structure of the eukaryotic cell. Biochemically similar to the rough endoplasmic reticulum, but lacks the ribosome binding function. Tends to be tubular rather than sheet like, may be separate from the rough endoplasmic reticulum or may be an extension of it. Abundant in cells concerned with lipid metabolism and proliferates in hepatocytes when animals are challenged with lipophilic drugs. Acronym: SER (18 Nov 1997) |
| UDP-GlcNAc - Ser-protein N-acetylglucosamine-1-phosphotransferase | <enzyme> Catalyses the transfer of n-acetylglucosamine-1-phosphate residues from udp-glcnac to serine units in proteins Registry number: EC 2.7.8.- Synonym: glcnac-1-p-ser transferase (26 Jun 1999) |
| partial denture retention | The fixation of a removable partial denture by the use of clasps, indirect retainers, or precision attachments. (05 Mar 2000) |
| retention | 1. The persistent keeping within the body of matters normally excreted. 2. In cavity preparation, the prevention of displacement of a restoration. 3. <dentistry> The period during which the patient is wearing an appliance to maintain and stabilise the teeth in the position into which they were moved. 4. <psychology> The persistence to perform a learned behaviour (facts or experiences) after an interval has elapsed in which there has been no performance or practice of the behaviour. Origin: L. Retentio, from retentare = to hold firmly back (18 Nov 1997) |
| retention area | An area of a tooth provided during its preparation for restoration that will aid in holding the restoration in place. See: retention groove, retention point. (05 Mar 2000) |
| retention arm | A flexible segment of a removable partial denture that engages an undercut on an abutment and is designed to retain the denture. (05 Mar 2000) |
| retention cyst | A cyst resulting from some obstruction to the excretory duct of a gland. Synonym: distention cyst, secretory cyst. (05 Mar 2000) |
| retention form | The shape of a cavity preparation that prevents displacement of the dental restoration by lateral or tipping forces as well as masticatory forces. (05 Mar 2000) |
| retention groove | One of the groove's forming opposing vertical constrictions in a tooth to aid in retention of a dental restoration. (05 Mar 2000) |
| retention jaundice | Jaundice due to insufficiency of liver function or to an excess of bile pigment production; the bilirubin is unconjugated because it has not passed through the liver cells; van den Bergh test is indirect. (05 Mar 2000) |
| retention point | A provision made within a cavity preparation of a tooth to hold in place the first pieces of gold when placing a direct gold restoration. (05 Mar 2000) |
| retention polyp | A smoothly rounded mucosal hamartoma of the large bowel, which may be multiple and cause rectal bleeding, especially in the first decade of life; it is not precancerous. Synonym: retention polyp. (05 Mar 2000) |
| retention suture | <surgery> A heavy reinforcing suture placed deep within the muscles and fasciae of the abdominal wall to relieve tension on the primary suture line and thus obviate postoperative wound disruption. Synonym: tension suture. (05 Mar 2000) |
| retention vomiting | <gastroenterology, physiology> Vomiting due to mechanical obstruction, usually hours after ingestion of a meal. (05 Mar 2000) |
