| systemic autoimmune diseases | A group of connective tissue disease's characterised by the presence of autoantibodies responsible for immunopathologically mediated tissue lesions; systemic lupus erythematosus is the prototype. (05 Mar 2000) |
|---|---|
| thyroiditis, autoimmune | A progressive disease of the thyroid gland with antibodies in the blood stream directed against the thyroid and infiltration of the gland by lymphoctes (a key type of white blood cells involved in the immune response). This immune response is against one's own thyroid. (it is autoimmune.) predominantly affects women. Can be familial. Also called hashimoto's disease or hashimoto's thyroiditis. (12 Dec 1998) |
| ammonia fixation | The utilization of ammonia (or ammonium ions) in the net synthesis of nitrogen-containing molecules; e.g., glutamine synthetase. Synonym: ammonia fixation. (05 Mar 2000) |
| bifoveal fixation | A condition in which both eyes are simultaneously directed to the same target. Synonym: bifoveal fixation. (05 Mar 2000) |
| binocular fixation | A condition in which both eyes are simultaneously directed to the same target. Synonym: bifoveal fixation. (05 Mar 2000) |
| carbon fixation | <plant biology> The process by which photosynthetic organisms such as plants turn inorganic carbon (usually carbon dioxide) into organic compounds (us. Carbohydrates). (09 Oct 1997) |
| mandibulomaxillary fixation | Fixation of fractures of the mandible or maxilla by applying elastic bands or stainless steel wire between the maxillary and mandibular arch bars or other types of splint. Synonym: mandibulomaxillary fixation, maxillomandibular fixation. (05 Mar 2000) |
| genes, nitrogen fixation | Regulatory and structural genes present in certain bacteria, algae and fungi that control the conversion of atmospheric nitrogen into biologically usable compounds; include nif structural genes (e.g., nifd, nifh) for nitrogenase and nitrate reductase as well as regulator genes nifa, nifb, ntra, ntrb, ntrc. Some are responsible for regulating transcription of genes involved in the assimilation of poor nitrogen sources in enteric bacteria. (12 Dec 1998) |
| genetic fixation | The increase of the frequency of a gene by genetic drift until no other allele is preserved in a specific finite population. (05 Mar 2000) |
| Gibney's fixation bandage | A herring-bone strapping of the foot and leg for sprain of the ankle. (05 Mar 2000) |
| maxillomandibular fixation | Fixation of fractures of the mandible or maxilla by applying elastic bands or stainless steel wire between the maxillary and mandibular arch bars or other types of splint. Synonym: mandibulomaxillary fixation, maxillomandibular fixation. (05 Mar 2000) |
| Roger-Anderson pin fixation appliance | An appliance used in extraoral fixation of mandibular fractures and prognathic corrections in which pins placed in the bone segments are joined by metal connecting rods. See: external pin fixation. (05 Mar 2000) |
| circumalveolar fixation | Stabilization of a fracture segment or surgical splint by wire passed through and around the dental alveolar process. (05 Mar 2000) |
| circummandibular fixation | Stabilization of a fracture segment or surgical splint by wire passed around the mandible. (05 Mar 2000) |
| circumzygomatic fixation | Stabilization of a fracture segment or surgical splint by wire passed around the zygomatic arch. (05 Mar 2000) |
