| diagnostic techniques, surgical | Methods and procedures for the diagnosis of disease or dysfunction by examination of the pathological site or operative field during surgical intervention. (12 Dec 1998) |
|---|---|
| diagnostic techniques, urological | Methods and procedures for the diagnosis of diseases or dysfunction of the urinary tract or its organs or demonstration of its physiological processes. (12 Dec 1998) |
| immunoenzyme techniques | Immunologic techniques based on the use of: 1) enzyme-antibody conjugates; 2) enzyme-antigen conjugates; 3) antienzyme antibody followed by its homologous enzyme; or 4) enzyme-antienzyme complexes. These are used histologically for visualizing or labeling tissue specimens. (12 Dec 1998) |
| immunosorbent techniques | Techniques for removal by adsorption and subsequent elution of a specific antibody or antigen using an immunosorbent containing the homologous antigen or antibody. (12 Dec 1998) |
| indicator dilution techniques | Methods for assessing flow through a system by injection of a known quantity of an indicator, such as a dye, radionuclide, or chilled liquid, into the system and monitoring its concentration over time at a specific point in the system. (12 Dec 1998) |
| investigative techniques | Investigative techniques used in pre-clinical and clinical research, epidemiology, chemistry, immunology, genetics, etc. They do not include techniques specifically applied to diagnosis; therapeutics; anaesthesia and analgesia, surgery, operative, and dentistry. (12 Dec 1998) |
| jaw fixation techniques | The stable placement of surgically induced fractures of the mandible or maxilla through the use of elastics, wire ligatures, arch bars, or other splints. It is used often in the cosmetic surgery of retrognathism and prognathism. (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) |
| fluorescent antibody techniques | Lab techniques for locating antigens in a prepared tissue sample by using antibodies with fluorescent labels which will bind to the antigens of interest. (09 Oct 1997) |
| American Type Culture Collection | <cell culture> A key resource for cultured cells, located in Rockville, USA. (12 Dec 1998) |
| 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) |
| anoxic culture | A culture of anaerobicmicrobes which use inorganic substances other thanoxygen as their terminal electron acceptors. (09 Oct 1997) |
| anther culture | A plant culturing technique in which immature pollen is made to divide andgrow into tissue (either callus or embryonic tissue) in either aliquidmedium or on solid media. Pollen-containing anthers are removed from aflower and put in a culture medium, some microspheres survive and developinto tissue. If embryonic tissue develops, its put in a medium favorablefor shoot and root development, if its callus tissue, its put in asolution of hormones that will spur it to differentiate and develop shootand root tissue. (09 Oct 1997) |
| axenic culture | <cell culture, microbiology> A culture that contains only one microbial species. (02 Jan 1998) |
| batch culture | A closed system culture of microorganisms with specific nutrient types, temperature, pressure, aeration, and other environmental conditions, where only a few generations are allowed to grow before all nutrients are used up. Compare: continuous culture. (09 Oct 1997) |
