| normal horse serum | The sterile and filtered serum of a healthy, unvaccinated horse. (05 Mar 2000) |
|---|---|
| normal human plasma | Sterile plasma obtained by pooling approximately equal amounts of the liquid portion of citrated whole blood from eight or more adult humans who have been certified as free from any disease which is tranmissible by transfusion, and treating it with ultraviolet irradiation to destroy possible bacterial and viral contaminants. (05 Mar 2000) |
| normal human serum | Sterile serum obtained by pooling approximately equal amounts of the liquid portion of coagulated whole blood from eight or more persons who are free from any disease transmissible by transfusion. (05 Mar 2000) |
| normal human serum albumin | A sterile preparation of serum albumin obtained by fractionating blood plasma proteins from healthy persons; used as a transfusion material and to treat oedema due to hypoproteinaemia. Synonym: dried human albumin. (05 Mar 2000) |
| normal occlusion | That arrangement of teeth and their supporting structure which is usually found in health and which approaches an ideal or standard arrangement. Synonym: normal bite. Synonym: neutral occlusion. (05 Mar 2000) |
| normal opsonin | That normally present in the blood, i.e., without stimulation by a known, specific antigen such as certain complement components; it is relatively thermolabile and reacts with various organisms. Synonym: common opsonin, thermolabile opsonin. Specific opsonin, antibodies formed in response to stimulation by a specific antigen, either as a result of an attack of a disease, or injections with a suitably prepared suspension of the specific microorganism. Synonym: immune opsonin, thermostable opsonin. (05 Mar 2000) |
| normal pressure hydrocephalus | <neurology> A brain disorder caused by blockage of the flow of cerebrospinal fluid (CSF), with enlargement of the ventricles of the brain (keep the pressure normal) and compression of brain tissue. Brain atrophy is the result. In this condition the CSF is produced normally but not reabsorbed. Symptom onset is gradual. A key feature is dementia. Treatment is surgical (VP shunt). (13 Nov 1997) |
| normal range | Normal results can fall outside the normal range. By convention, the normal range is set to cover ninety-five percent (95%) of values from a normal population. Five percent (5%) of normal results therefore fall outside the normal range. (12 Dec 1998) |
| normal serum | A nonimmune serum, usually with reference to a serum obtained prior to immunization. (05 Mar 2000) |
| normal tartrate | Tartrate that contains no uncombined acid groups. (05 Mar 2000) |
| normal toxin | A toxin solution holding exactly 100 lethal doses in 1 ml. (05 Mar 2000) |
| acetyl value | The milligrams of KOH required to neutralise the acetic acid produced by the hydrolysis of 1 g of acetylated fat; a measure of the hydroxy acids present in glycerides; notably high in castor oil. (05 Mar 2000) |
| beta, or beta-value | <radiobiology> Ratio of plasma kinetic pressure to magnetic-field pressure, proportional to the ratio of plasma kinetic energy density to magnetic field energy density. Beta is usually measured relative to the total, local field (loosely called beta toroidal), but sometimes the plasma pressure relative to only the poloidal component of the field (beta poloidal) or relative to some external field (like the maximum field at the magnetic coils) is more useful. There is also a normalised beta (beta_N) of interest when discussing the beta limit. (lots of help from Art Carlson with the above.) Because the cost of a reactor is strongly influenced by the strength of the magnetic field that must be provided, beta values are directly related to the economics of fusion power production. Beta is usually expressed as a percentage, with 5% generally believed to be the minimum value required for an economical fusion reactor. See: pressure, kinetic pressure, magnetic pressure, second stability. (09 Oct 1997) |
| biological value | <nutrition> The nutritional value of a protein, usually measured in comparison to the nutritional value of egg protein, which is the highest possible (BV=0.9 - 1.00). (21 Mar 1998) |
| buffer value | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
