What's the difference between attenuate and tenuate?
Attenuate
Definition:
(v. t.) To make thin or slender, as by mechanical or chemical action upon inanimate objects, or by the effects of starvation, disease, etc., upon living bodies.
(v. t.) To make thin or less consistent; to render less viscid or dense; to rarefy. Specifically: To subtilize, as the humors of the body, or to break them into finer parts.
(v. t.) To lessen the amount, force, or value of; to make less complex; to weaken.
(v. i.) To become thin, slender, or fine; to grow less; to lessen.
(a.) Alt. of Attenuated
Example Sentences:

(5) These results indicate that during IPPV the increased Pcv attenuates the pressure gradient for venous return and decreases CO and that the compensatory increase in Psf is caused by a blood shift from unstressed to stressed blood volume.
(6) Mild, significant improvement was noted in one of the hearing components, "attenuation," and an adverse effect was shown on "distortion," owing to noise.
(7) It inhibits platelet and vascular smooth muscle activation by cGMP-dependent attenuation of the agonist-induced rise of intracellular free Ca2+.
(8) Genetic regulation of the ilvGMEDA cluster involves attenuation, internal promoters, internal Rho-dependent termination sites, a site of polarity in the ilvG pseudogene of the wild-type organism, and autoregulation by the ilvA gene product, the biosynthetic L-threonine deaminase.
(9) Pharmacodynamic relationships are not well established for other therapeutic effects of theophylline, such as attenuation of pharmacologically induced bronchoconstriction.
(10) Propranolol, 0.85 X 10(-6) M, did not significantly depress the ouabain-enhanced rate of phase 4 depolarization but did attenuate the response to epinephrine through beta blockade.

(15) Our dynamic study indicated that: 1) a bolus injection of contrast medium with our method of CTA (CTA-B) produced an attenuation difference between liver and tumor which was about double that obtained with standard methods for CTA, and 2) marked tumor-liver attenuation differences (above 20 HU) persisted for more than 60 s in CTA-B and for not more than 20 s with conventional methods for CTA.
(16) It appears that the viscosity of the arterial wall must be the major source of attenuation in the larger arteries, while the viscosity of the blood plays a significant role only in the smaller vessels.

Tenuate
Definition:
(v. t.) To make thin; to attenuate.
Example Sentences:
