| type a personality | Established behaviour pattern characterised by excessive drive and ambition, impatience, competitiveness, sense of time urgency, and poorly contained aggression. (12 Dec 1998) |
|---|---|
| type B behaviour | A behaviour pattern characterised by the absence or obverse of type A behaviour characteristics. (05 Mar 2000) |
| type culture | A type strain of microorganism preserved in a culture collection as the standard. (05 Mar 2000) |
| type genus | <zoology> The type of a taxon at the family group level - the nominal genus. (09 Jan 1998) |
| type horizon | <zoology> The geological stratum from which the name-bearing type of a nominal species or subspecies was collected. (09 Jan 1998) |
| type host | <zoology> The host species with which the name-bearing type of a nominal species or subspecies was associated. (09 Jan 1998) |
| type I acrocephalosyndactyly | <paediatrics> A usually inherited disorder characterised by premature closing of the cranial suture lines resulting in a peaked shaped head and abnormal facial appearance. Since it is usually autosomal dominant one or both parents also have the disorder. Surgery is used to correct skull and facial abnormalities. Inheritance: autosomal dominant. (29 Dec 1997) |
| type I cells | Highly attentuated squamous cell's that form the gas-permeable epithelium lining the alveoli of the lungs. Synonym: type I cells. (05 Mar 2000) |
| type I collagen | The most abundant collagen, which forms large well-organised fibrils having high tensile strength. (05 Mar 2000) |
| type I diabetes | A chronic condition in which the pancreas makes little or no insulin because the beta cells have been destroyed. The body is then not able to use the glucose (blood sugar) for energy. IDDM usually comes on abruptly, although the damage to the beta cells may begin much earlier. The signs of IDDM are a great thirst, hunger, a need to urinate often, and loss of weight. To treat the disease, the person must inject insulin, follow a diet plan, exercise daily, and test blood glucose several times a day. IDDM usually occurs in children and adults who are under age 30. This type of diabetes used to be known as juvenile diabetes, juvenile-onset diabetes, and ketosis-prone diabetes. (09 Oct 1997) |
| type I diabetes mellitus | <endocrinology> A severe metabolic disorder which has an abrupt onset before the age of twenty. In it, an insulin deficiency prevents the body from using carbohydrates properly and forces it to rely mainly on protein metabolism. Treatment of the disease includes strict dietary regulation and mandatory insulin injections. (09 Oct 1997) |
| type I dip | Early deceleration of the foetal heart rate at the height of uterine contraction, as displayed on a foetal monitor graph. (05 Mar 2000) |
| type i error | The statistical error (said to be of the first kind or alpha error) made in testing an hypothesis when it is concluded that a treatment or intervention is effective when it really is not. Sometimes referred to as a false positive. (12 Dec 1998) |
| type I familial hyperlipoproteinaemia | Hyperlipoproteinaemia characterised by the presence of large amounts of chylomicrons and triglycerides in the plasma when the patient has a normal diet, and their disappearance on a fat-free diet; low alpha-and beta-lipoproteins on a normal diet, with increase on fat-free diet; decreased plasma postheparin lipolytic activity; and low tissue lipoprotein lipase activity. It is accompanied by bouts of abdominal pain, hepatosplenomegaly, pancreatitis, and eruptive xanthomas; autosomal recessive inheritance. See: familial lipoprotein lipase inhibitor. Synonym: Burger-Grutz syndrome, familial fat-induced hyperlipaemia, familial hyperchylomicronaemia, familial hypertriglyceridemia, idiopathic hyperlipaemia. (05 Mar 2000) |
| type IH mucopolysaccharidosis | <syndrome> Mucopolysaccharidosis in which there is a deficiency of alpha-l-iduronidase, an accumulation of an abnormal intracellular material, and excretion of dermatan sulfate and heparan sulfate in the urine; with severe abnormality in development of skeletal cartilage and bone, with dwarfism, kyphosis, deformed limbs, limitation of joint motion, spadelike hand, corneal clouding, hepatosplenomegaly, mental retardation, and gargoyle-like facies; autosomal recessive inheritance. See: mucolipidosis. Synonym: dysostosis multiplex, Hurler's disease, lipochondrodystrophy, Pfaundler-Hurler syndrome, type IH mucopolysaccharidosis. (05 Mar 2000) |
