|---|---|
| sensitivity | <microscopy> Similar to responsively of an image pickup tube but numerically different. The signal current developed in an image pickup tube per unit incident radiation density (watt per unit area) or illuminance (lux on the faceplate). Unless otherwise specified, the radiation is understood to be that of an unfiltered incandescent source at 2854 or 2856[[macron]]K. (05 Aug 1998) |
| sensitivity and specificity | Measures for assessing the results of diagnostic and screening tests. Sensitivity represents the proportion of truly diseased persons in a screened population who are identified as being diseased by the test. It is a measure of the probability of correctly diagnosing a condition. Specificity is the proportion of truly nondiseased persons who are so identified by the screening test. It is a measure of the probability of correctly identifying a nondiseased person. (12 Dec 1998) |
| sensitivity training group | A group in which members seek to develop self-awareness and an understanding of group processes rather than to obtain therapy for an emotional disturbance. See: encounter group, personal growth laboratory. (05 Mar 2000) |
| sensitivity training groups | A group of people who meet in an unstructured setting to learn about themselves, interpersonal relationships, and group processes and about larger social systems. (12 Dec 1998) |
| small increment sensitivity index | The sounding of a tone 20 dB above threshold, followed by a series of 200-msec tones 1 dB louder; perception of these is indicative of cochlear damage. Synonym: small increment sensitivity index test. (05 Mar 2000) |

| spectral sensitivity | The reciprocal of the amount of monochromatic radiation that produces a fixed response. (05 Mar 2000) |
| diagnostic sensitivity | The probability (P) that, given the presence of disease (D), an abnormal test result (T) indicates the presence of disease; i.e., P(T/D). See: clinical sensitivity. (05 Mar 2000) |
| disk sensitivity method | A procedure for testing the relative effectiveness of various antibiotics; small disks of paper (or other suitable material) are impregnated with known, appropriate amounts of antibiotic, and then placed on the surface of semisolid medium that has been previously inoculated with the organism being tested; after suitable periods of incubation at 37캜, the lack of growth in zones about the various disks indicates the relative effectiveness of the antibiotic. (05 Mar 2000) |
| DNAse i sensitivity | <molecular biology> The likelihood that a particular DNA segment will be attacked by the endonuclease enzyme DNase I, which breaks down DNA into smaller fragments by cleaving its phosphodiester bonds. DNA segments which contain active genes that are regularly transcribed are more prone to being cut apart by DNase I than inactivated genes, because the inactivated genes are generally within condensed regions of the chromosome, while the active genes are in more open configurations for easy access for transcription. (09 Oct 1997) |
| idiosyncratic sensitivity | A type I allergic reaction (atopic). (05 Mar 2000) |
| induced sensitivity | 1. <immunology> A state of hypersensitivity induced by exposure to a particular antigen (allergen) resulting in harmful immunologic reactions on subsequent exposures, the term is usually used to refer to hypersensitivity to an environmental antigen (atopic allergy or contact dermatitis) or to drug allergy. The original meaning, now obsolete, included all states of altered immunologic reactivity, immunity as well as hypersensitivity. Gell and Coombs used the term allergic reaction to mean any harmful immunologic reaction causing tissue injury. 2. <study> The medical specialty dealing with diagnosis and treatment of allergic disorders. (18 Nov 1997) |
| oligomycin sensitivity conferral protein | <protein> The _ subunit of the ATP synthase, believed to link the F1 catalytic segment to the F0 proton conduction segment. Binds the toxin oligomycin. (18 Nov 1997) |
| acute chemical pneumonitis | <chest medicine> Inflammation of the lungs which occurs secondary to exposure to a chemical, organic dust, fungus or mould. Chronic exposure can lead to chronic lung changes evident on chest X-ray. Symptoms include cough, fever, shortness of breath and wheezing. See: bird-handler's disease. (27 Sep 1997) |
