What's the difference between attenuate and attenuation?

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:

  • (1) This suggested that the chemical effects produced by shock waves were either absent or attenuated in the cells, or were inherently less toxic than those of ionizing irradiation.
  • (2) The results are consistent with our previous suggestion that lethality for virulent SFV infection results from a lethal threshold of damage to neurons in the CNS and that attenuating mutations may reduce neuronal damage below this threshold level.
  • (3) Exposure to nanomolar concentrations of saralasin, an Ang II agonist, attenuated the passage of the fluorophores across the monolayers by 50-75%.
  • (4) Furthermore, the ability of a vasopressin antagonist to lower arterial pressure in NTS hypertensive rats was markedly attenuated by clonidine treatment.
  • (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.
  • (11) After large bowel removal, there was impaired glucose tolerance and attenuated plasma insulin secretion.
  • (12) Studies were conducted in isolated, buffer-perfused rat lungs to determine if prostaglandin (PG) E1 attenuated pulmonary edema provoked by hydrogen peroxide (H2O2).
  • (13) The toxins preferentially attenuate a slow phase of KCl-evoked glutamate release which may be associated with synaptic vesicle mobilization.
  • (14) The Northern quahaug and a strain of the type 1 attenuated poliovirus were used as the working model.
  • (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.
  • (17) Fluid movement out of the ICF space attenuated the decrease in the ECF space.
  • (18) We show that the two mutants (A44 and A46) affect attenuator control by different mechanisms.
  • (19) The type I cells are squamous and give off attenuated sheets of cytoplasm which spread widely over the septal surface; these sheets contain few organelles.
  • (20) A sequence of seven pairings of chili-flavored diet with prompt recovery from thiamine deficiency did significantly attenuate the innate aversion and may have induced a chili preference in at least one case.

Attenuation


Definition:

  • (n.) The act or process of making slender, or the state of being slender; emaciation.
  • (n.) The act of attenuating; the act of making thin or less dense, or of rarefying, as fluids or gases.
  • (n.) The process of weakening in intensity; diminution of virulence; as, the attenuation of virus.
