(1) The vascular endothelium is capable of regulating tissue perfusion by the release of endothelium-derived relaxing factor to modulate vasomotor tone of the resistance vasculature.
(2) In summary, GABAergic tone did not effect basal acid secretion in anesthetized rats.
(3) After midazolam infusion, there was a 50% decrease in amplitude of P3 in response to target tones (P less than 0.006), whereas N3 latency increased by 40 ms (P less than 0.05).
(4) All of this in the same tones of weary nonchalance you might use to stop the dog nosing around in the bin.
(5) More disturbing than his ideas was Malema's style and tone.
(6) Noradrenaline decreased the phasic contraction amplitude of the circular muscle and exerted a stimulant effect on the tone which suggested an existence of two alpha 1-adrenoceptor subtypes.
(7) Histamine (10(-6)-10(-4) M) induced concentration-dependent increases in tone and Ca2+i, but these responses were not sustained.
(8) Masking experiments are demonstrated for electrical frequency-modulated tone bursts from 1,000 to 10,000 cps and from 10,000 to 1,000 cps with superimposed clicks.
(9) The stimuli were two simple tones in experiment 1 and two tonal complexes in both experiments 2 and 3.
(10) Isolated outer hair cells from the organ of Corti of the guinea pig have been shown to change length in response to a mechanical stimulus in the form of a tone burst at a fixed frequency of 200 Hz (Canlon et al., 1988).
(11) Complex tones containing the first 20 harmonics of 50, 100, or 200 Hz, all at equal amplitude, were used.
(12) An attempt to eliminate the age effect by adjusting for age differences in monaural shadowing errors, fluid intelligence, and pure-tone hearing loss did not succeed.
(13) Inhibition of the production or action of these substances will allow for vasodilatation, and it is probable that perinatal pulmonary vascular tone reflects a balance between local prostaglandin and leukotriene production.
(14) Subject evaluations in accordance with the intensity levels of tones, i.e.
(15) Maximum expiratory flow on partial flow-volume curve at 25% forced vital capacity (PEF25) was measured as an index showing basal bronchomotor tone.
(16) Twenty-four hours later, a stimulus generalization test was conducted in the absence of drug; during this session, tones that varied in frequency around 4.5 KHz were presented while the animals were responding under the VI schedule.
(17) Auditory sensory perception was operationalized as number of tones heard on audiometric examination.
(18) Later, Lucas, also a former party leader, strongly defended Bennett, saying it was a “bad day for Natalie” but there was also “kind of a gloating tone that strikes one as having something to do with her being a woman in there too”.
(19) From a set of tones that varied only in intensity, it was possible to calculate the growth of loudness with intensity for the budgerigar.
(20) Two hundred forty-six fetuses had at least one abnormal biophysical profile variable with the risk of bad outcome, for a single abnormal variable, ranging from 8% (body movements) to 100% (tone) and increasing from 14% (any variable abnormal) to 63% (all variables abnormal).
