| Vater, Abraham | <person> Was a student and follower of Ruysch in Amsterdam. Wrote on a wide range of anatomical subjects between 1707 and 1750. Was Professor of Anatomy and Botany in Wittenburg (1719) and later (1737) Professor of Pathology and Therapeutics in the same University. Vater's Tubercle - papilla duodeni - papilla of Santorini. Vater's Ampulla - ampulla of the bile duct. Lived: 1684-1751. B. Wittenburg, Dec 9th, 1684, d. Wittenburg, Nov 18th, 1751. (05 Dec 1998) |
| Vater-Pacini corpuscles | Small oval bodies in the skin of the fingers, in the mesentery, tendons, and elsewhere, formed of concentric layers of connective tissue with a soft core in which the axon of a nerve fibre runs, splitting up into a number of fibrils that terminate in bulbous enlargements; they are sensitive to pressure. Synonym: corpuscula lamellosa, pacinian corpuscles, Vater's corpuscles, Vater-Pacini corpuscles. (05 Mar 2000) |
| Vater's ampulla | The dilatation formed by junction of the common bile duct and the pancreatic ducts proximal to their opening into the lumen of the duodenum. (12 Dec 1998) |

Synonym: corpuscula lamellosa, pacinian corpuscles, Vater's corpuscles, Vater-Pacini corpuscles. (05 Mar 2000) |
| Vater's fold | A fold of mucous membrane in the duodenum just above the greater duodenal papilla. (05 Mar 2000) |
| vater syndrome | <radiology> V vertebral anomalies vascular anomalies, A anal atresia, T tracheo-oesophageal fistula, E oesophageal atresia, R renal anomalies radial dysplasia (12 Dec 1998) |
| papilla of Vater | Point of opening of the common bile duct and pancreatic duct into the duodenum; it is located posteriorly in the descending part of the duodenum. Synonym: papilla duodeni major, bile papilla, papilla of Vater, Santorini's major caruncle. (05 Mar 2000) |
| aberrant complex | An anomalous electrocardiographic complex, more specifically an abnormal ventricular complex caused by abnormal intraventricular conduction of a supraventricular impulse. (05 Mar 2000) |
| activated complex | <chemistry> State of highest energy during a reaction. When reactants form the activated complex, bond breaking and bond formation is occurring. Synonym: transition state. (09 Jan 1998) |
| AIDS dementia complex | <immunology> A frequent cerebral condition in people with AIDS that results in the loss of cognitive capacity, affecting the ability to function in a social or occupational setting. Its cause has not been determined exactly, but may result from HIV infection of cells in the brain or an inflammatory reaction to such infection. (09 Oct 1997) |
| aids-related complex | A prodromal phase of infection with the human immunodeficiency virus (HIV). Laboratory criteria separating aids-related complex (arc) from aids include elevated or hyperactive B-cell humoral immune responses, compared to depressed or normal antibody reactivity in aids; follicular or mixed hyperplasia in arc lymph nodes, leading to lymphocyte degeneration and depletion more typical of aids; evolving succession of histopathological lesions such as localization of kaposi's sarcoma, signaling the transition to the full-blown aids. (12 Dec 1998) |
| alpha-keto acid dehydrogenase complex | See: alpha-keto acid dehydrogenase. Anaerobic dehydrogenase, an enzyme (usually a pyridinoenzyme) catalyzing the transfer of hydrogen from some metabolite to some acceptor molecule (e.g., NAD+, cytochrome) other than oxygen; e.g., lactate dehydrogenase's, isocitrate dehydrogenase's, and others in EC class 1, excluding those listed under aerobic dehydrogenase.
