| laboratory diagnosis | A diagnosis made by a chemical, microscopic, microbiologic, immunologic, or pathologic study of secretions, discharges, blood, or tissue. (05 Mar 2000) |
|---|---|
| laboratory infection | Accidentally acquired infection in laboratory workers. (12 Dec 1998) |
| laboratory personnel | Those health care professionals, technicians, and assistants staffing a research or health care facility where specimens are grown, tested, or evaluated and the results of such measures are recorded. (12 Dec 1998) |
| laboratory techniques and procedures | Methods, procedures, and tests performed in the laboratory with an intended application to the diagnosis of disease or understanding of physiological functioning. The techniques include examination of microbiological, cytological, chemical, and biochemical specimens, normal and pathological. (12 Dec 1998) |
| los alamos national laboratory | <radiobiology> Major DOE research facility, located in Los Alamos, new Mexico, about an hour west of Santa Fe. Former home of a frozen-deuterium-fibre Z-pinch device, which was dismantled. Home to an active theory division, including the Numerical Tokamak Grand Challenge (being performed on the CM-5 massively-parallel supercomputer). Also home to former alternative-concepts experimental devices like Scyllac, FRX-A, FRX-B, FRX-C/LSM, ZT40, and the aborted CPRF which was killed in 1991 when it was almost complete (budget cuts). Currently there are some small in-house experiments, including one on electrostatic confinement as a possible fusion device, and/or a compact neutron source. They also do theory and experimental collaboration with other labs worldwide. (09 Oct 1997) |
| animal | 1. An organised living being endowed with sensation and the power of voluntary motion, and also characterised by taking its food into an internal cavity or stomach for digestion; by giving carbonic acid to the air and taking oxygen in the process of respiration; and by increasing in motive power or active aggressive force with progress to maturity. 2. One of the lower animals; a brute or beast, as distinguished from man; as, men and animals. Origin: L, fr. Anima breath, soul: cf. F. Animal. See Animate. 1. Of or relating to animals; as, animal functions. 2. Pertaining to the merely sentient part of a creature, as distinguished from the intellectual, rational, or spiritual part; as, the animal passions or appetites. 3. Consisting of the flesh of animals; as, animal food. Animal magnetism. See Magnetism and Mesmerism. Animal electricity, the electricity developed in some animals, as the electric eel, torpedo, etc. <physiology> Animal flower, the heat generated in the body of a living animal, by means of which the animal is kept at nearly a uniform temperature. Animal spirits. See Spirit. Animal kingdom, the whole class of beings endowed with animal life. It embraces several subkingdoms, and under these there are Classes, Orders, Families, Genera, Species, and sometimes intermediate groupings, all in regular subordination, but variously arranged by different writers. The following are the grand divisions, or subkingdoms, and the principal classes under them, generally recognised at the present time: - Vertebrata, including Mammalia or Mammals, Aves or Birds, Reptilia, Amphibia, Pisces or Fishes, Marsipobranchiata (Craniota); and Leptocardia (Acrania). Tunicata, including the Thaliacea, and Ascidioidea or Ascidians. Articulata or Annulosa, including Insecta, Myriapoda, Malacapoda, Arachnida, Pycnogonida, Merostomata, Crustacea (Arthropoda); and Annelida, Gehyrea (Anarthropoda). Helminthes or Vermes, including Rotifera, Chaetognatha, Nematoidea, Acanthocephala, Nemertina, Turbellaria, Trematoda, Cestoidea, Mesozea. Molluscoidea, including Brachiopoda and Bryozoa. Mollusca, including Cephalopoda, Gastropoda, Pteropoda, Scaphopoda, Lamellibranchiata or Acephala. Echinodermata, including Holothurioidea, Echinoidea, Asterioidea, Ophiuroidea, and Crinoidea. Coelenterata, including Anthozoa or Polyps, Ctenophora, and Hydrozoa or Acalephs. Spongiozoa or Porifera, including the sponges. Protozoa, including Infusoria and Rhizopoda. For definitions, see these names in the Vocabulary. Origin: Cf. F. Animal. Source: Websters Dictionary (01 Mar 1998) |
| animal black | Charcoal produced by incomplete combustion of animal tissues, especially bone. Synonym: animal black, bone black, bone charcoal. (05 Mar 2000) |
| animal cell culture | <cell culture> Mammalian cells are fragile and harder to grow than other cell types, but their large-scale culturing is an economic boon because it allows for the production of proteins that are otherwise difficult or expensive or unethical to extract from living organisms. The cells are immobilised on a substrate and then perfused with culture medium, The cells are in a free suspension which is very gently mixed and aerated. (12 Nov 1997) |
| animal cell immobilisation | <cell culture> Animal cells are widely used in biotechnology to produce genetically engineered proteins. However, they are more fragile than bacterial cells, and immobilising the cell facilitates the fermentation process. Many animal cells stick down flat on a suitable surface, hugging it as they would hug other cells or connective matrices in the body. If grown on suitable plastic surfaces, on glass or many ceramics, these cells will stick to them. In this way, they are easier to grow. (14 Nov 1997) |
| animal charcoal | Charcoal produced by incomplete combustion of animal tissues, especially bone. Synonym: animal black, bone black, bone charcoal. (05 Mar 2000) |
| animal communication | Communication between animals involving the giving off by one individual of some chemical or physical signal, that, on being received by another, influences its behaviour. (12 Dec 1998) |
| animal dander | <immunology, zoology> The epidermis (skin) from an animal that can elicit an allergic response. (12 Nov 1997) |
| animal dextran | <biochemistry> Branched polymer of D glucose (mostly _(1-4) linked, but some _(1-6) at branch points). Size range very variable, up to 10exp5 glucose units. Major short term storage polymer of animal cells and is particularly abundant in the liver and to a lesser extent in muscle. In the electron microscope glycogen has a characteristic asterisk or star appearance. (18 Nov 1997) |
| animal graft | A graft of tissue from an animal to a human. Synonym: animal graft, zooplastic graft. (05 Mar 2000) |
| animal husbandry | The science of breeding, feeding and care of domestic animals; includes housing and nutrition. (12 Dec 1998) |
