| arsenite(antimonate)-stimulated ATPase | <enzyme> Anion pump with 2 polypeptide components (arsa and arsb); arsa is the catalytic subunit of an oxyanion-translocating atpase; arsb protein has been localised in the inner membrane of E coli; arsc protein required for arsenate resistance; reduces arsenate to arsenite Registry number: EC 3.6.1.- Synonym: arsa protein, arsb protein, ars gene product, arsc protein, anion-translocating atpase, arsenical resistance pump, oxyanion pump, arsenate reductase (26 Jun 1999) |
| vasodilator stimulated phosphoprotein | <protein> A 46/50 kD protein that is a substrate for both cAMP and cGMP dependent protein kinases and that is associated with microfilament bundles in many tissue cells. Abundant in platelets, phosphorylation of VASP will inhibit platelet activation. (18 Nov 1997) |
| stimulated emission | <radiobiology> Radiation coherently emitted by excited ions when driven by a passing light wave and the appropriate transition wavelength. Laser means Light Amplification by Stimulated Emission of Radiation, it occurs when there is a population inversion between the upper and lower energy states of the transition, such that stimulated emission can dominate excitation. Stimulated emission is coherent and codirectional with the stimulating wave, and the rate of stimulated emission is proportional to the intensity of the stimulating wave. (09 Oct 1997) |
| A-mode | In diagnostic ultrasound, a one-dimensional presentation of a reflected sound wave in which echo amplitude (A) is displayed along the vertical axis and time of rebound (depth) along the horizontal axis; the echo information is presented from interfaces along a single line in the direction of the sound beam. (05 Mar 2000) |
| atrial echo | Electrical reactivation of the atrium by a retrograde impulse returning from the A-V node while the antegrade impulse continues to the ventricle; characterised electrocardiographically, by a pair of P waves enclosing a QRS complex, the second P wave being inverted, indicating that it is the reverse (the retrograde pathway) of the pathway of the first P wave (the antegrade pathway). (05 Mar 2000) |
| ballooning mode | <radiobiology> A mode which is localised in regions of unfavorable magnetic field curvature (bad curvature) and which becomes unstable when the force due to pressure gradients (grad p) is greater than the mean magnetic pressure force (grad B^2)/(8pi) in cgs units. (09 Oct 1997) |
| Bernstein mode | <radiobiology> Type of mode which propagates perpendicular to the equilibrium magnetic field in a hot plasma. The waves have their electric field nearly parallel to the wave propagation vector (nearly longitudinal). The modes propagate in frequency ranges lying between integer harmonics of the electron cyclotron frequency. Named after Ira Bernstein. (09 Oct 1997) |
| B-mode | A two-dimensional diagnostic ultrasound presentation of echo-producing interfaces in a single plane; the intensity of the echo is represented by modulation of the brightness (B) of the spot, and the position of the echo is determined from the position of the transducer and the transit time of the acoustical pulse. (05 Mar 2000) |
| B-mode echocardiography | two-dimensional echocardiography |
| M-mode | A diagnostic ultrasound presentation of the temporal changes in echoes in which the depth of echo-producing interfaces is displayed along one axis with time (T) along the second axis; motion (M) of the interfaces toward and away from the transducer is displayed. Synonym: TM-mode. (05 Mar 2000) |
| mode | 1. Manner of doing or being; method; form; fashion; custom; way; style; as, the mode of speaking; the mode of dressing. "The duty of itself being resolved on, the mode of doing it may easily be found." (Jer. Taylor) "A table richly spread in regal mode." (Milton) 2. Prevailing popular custom; fashion, especially in the phrase the mode. "The easy, apathetic graces of a man of the mode." (Macaulay) 3. Variety; gradation; degree. 4. <psychology> Any combination of qualities or relations, considered apart from the substance to which they belong, and treated as entities; more generally, condition, or state of being; manner or form of arrangement or manifestation; form, as opposed to matter. "Modes I call such complex ideas, which, however compounded, contain not in them the supposition of subsisting by themselves, but are considered as dependencies on, or affections of, substances." (Locke) 5. <logic> The form in which the proposition connects the predicate and subject, whether by simple, contingent, or necessary assertion; the form of the syllogism, as determined by the quantity and quality of the constituent proposition; mood. 6. Same as Mood. 7. The scale as affected by the various positions in it of the minor intervals; as, the Dorian mode, the Ionic mode, etc, of ancient Greek music. In modern music, only the major and the minor mode, of whatever key, are recognised. 8. A kind of silk. See Alamode. Synonym: Method, manner. See Method. Origin: L. Modus a measure, due or proper measure, bound, manner, form; akin to E. Mete: cf. F. Mode. See Mete, and cf. Commodious, Mood in grammar, Modus. Source: Websters Dictionary (01 Mar 1998) |
| spin echo | A commonly used technique to recover T2 relaxation signals in magnetic resonance imaging, by using a 180 |
| nodus sinuatrialis echo | A postectopic sinus beat occurring earlier than would be expected from the preceding sinus node discharge interval; i.e., the interval following a premature beat of supraventricular origin is less than the ordinary cycle length between sinus beats, whereas ordinarily the interval would be expected to exceed cycle length. (05 Mar 2000) |
| tearing mode | <radiobiology> A resistive magnetohydrodynamic instability which is spatially localised near a rational surface and which grows at a rate slower than the magnetohydrodynamic Alfven rate, but faster than the resistive skin diffusion rate. The instability tears magnetic field lines and reconnects them into a new state of lower magnetic energy. Synonym: tearing instability (09 Oct 1997) |
