| type locality | <zoology> The geographical location of the occurrence of the population from which the type specimen was taken. Population occurring at type locality = topotypical population. Specimens collected at type locality = topotypes. (09 Jan 1998) |
|---|---|
| type material | <zoology> A collective term for all type specimens. Zoologists should ensure that such material is transferred as quickly as possible to public institutions where their safety is guaranteed and they are accessible to other workers. (09 Jan 1998) |
| type series | <zoology> The series of specimens which either constitutes the name-bearing type of a nominal species or subspecies or from which the name-bearing type has been or may be designated. (09 Jan 1998) |
| type species | <zoology> The nominal species that is the name-bearing type of a nominal genus or subgenus. (09 Jan 1998) |
| type specimen | <zoology> Any specimen of the type series. (09 Jan 1998) |
| type strain | The nomenclatural type of a species or subspecies. (05 Mar 2000) |
| type V acrocephalosyndactyly | Acrocephalosyndactyly with broad short thumbs and great toes, often with duplication (polydactyly) of the great toes and variable syndactyly of other digits; autosomal dominant inheritance. Synonym: Pfeiffer's syndrome. (05 Mar 2000) |
| type V familial hyperlipoproteinaemia | Hyperlipoproteinaemia characterised by increased plasma levels of chylomicrons, VLDL, pre-beta-lipoproteins, and triglycerides, and slight rise of cholesterol on a normal diet, with beta-lipoproteins normal; may be accompanied by bouts of abdominal pain, hepatosplenomegaly, susceptibility to atherosclerosis, and abnormal glucose tolerance; probably autosomal recessive inheritance. Synonym: combined fat-and carbohydrate-induced hyperlipaemia, familial hyperchylomicronaemia with hyperprebetalipoproteinaemia, mixed hyperlipaemia. (05 Mar 2000) |
| type VIII mucopolysaccharidosis | <syndrome> An autosomal recessive disorder due to a deficiency of a beta-glucuronidase; defective lysosomal degradation of dermatan sulfate, heparan sulfate, and chondroitin sulfate; cellular function disrupted in most tissues. Synonym: type VII mucopolysaccharidosis, type VIII mucopolysaccharidosis. (05 Mar 2000) |
| type VII mucopolysaccharidosis | <syndrome> An autosomal recessive disorder due to a deficiency of a beta-glucuronidase; defective lysosomal degradation of dermatan sulfate, heparan sulfate, and chondroitin sulfate; cellular function disrupted in most tissues. Synonym: type VII mucopolysaccharidosis, type VIII mucopolysaccharidosis. (05 Mar 2000) |
| type VI mucopolysaccharidosis | <biochemistry, syndrome> An error of mucopolysaccharide metabolism due to deficiency of the lysosomal enzyme arylsulphatase B. It is characterised by excretion of dermatan sulfate in the urine, growth retardation, lumbar kyphosis, sternal protrusion, genu valgum, usually hepatosplenomegaly, and no mental retardation. Onset occurs after two years of age. Inheritance: autosomal recessive. Synonym: polydystrophic dwarfism, mucopolysaccharidosis type VI. (05 Mar 2000) |
| type V mucopolysaccharidosis | Former designation for Scheie's syndrome. (05 Mar 2000) |
| Farr type assay | <investigation> Method of radioimmunoassay in which free antigen remains soluble and antibody antigen complexes are precipitated. (18 Nov 1997) |
| undifferentiated type fever | A term applied to illnesses resulting from infection by any one of the arboviruses pathogenic for man, in which the only constant manifestation is fever; rash, lymphadenopathy, or arthralgia (alone or in combination) may occur in some individuals but not in others; some arboviruses may induce infections in which undifferentiated type fever is the only manifestation, whereas other arboviruses may induce in some persons only undifferentiated fever, and in other persons similar fever followed by secondary manifestations, e.g., a haemorrhagic fever or encephalitis. (05 Mar 2000) |
| "e"-type cholinesterase | <enzyme, neurology, physiology> An enzyme that breaks down unused acetylcholine in the synaptic cleft (the space between neurons), this enzyme is necessary to restore the synaptic cleft so it is ready to transmit the next nerve impulse. (06 May 1997) |
