| nitrogen radioisotopes | Unstable isotopes of nitrogen that decay or disintegrate emitting radiation. N atoms with atomic weights 12, 13, 16, 17, and 18 are radioactive nitrogen isotopes. (12 Dec 1998) |

| nonprotein nitrogen | The nitrogen content of other than protein bodies; e.g., about one-half the nonprotein nitrogen in the blood is contained in urea. Synonym: rest nitrogen. (05 Mar 2000) |
| undetermined nitrogen | The nitrogen of blood, urine, etc., other than urea, uric acid, amino acids, etc., that can be directly estimated; in blood it amounts to about 25 mg per 100 ml. Urea nitrogen, the portion of nitrogen in a biological sample, such as blood or urine, that derives from its content of urea. See: blood urea nitrogen. (05 Mar 2000) |
| urinary nitrogen | Nitrogen excreted as urea, amino acids, uric acid, etc., in the urine; 1 g of urinary nitrogen indicates the breakdown in the body of 6.25 g of protein. See: nitrogen equivalent. (05 Mar 2000) |
| filtrate nitrogen | Nonprotein nitrogen in various compounds that normally pass through the glomerular filtration, or through a filter in the laboratory (after proteins are precipitated). (05 Mar 2000) |
| 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) |
| 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) |
