Uptake
Definition:
(v. t.) To take into the hand; to take up; to help.
(n.) The pipe leading upward from the smoke box of a steam boiler to the chimney, or smokestack; a flue leading upward.
(n.) Understanding; apprehension.
Example Sentences:

(2) 5-HT thus appears to be the preferred substrate for uptake into platelets and for movement from cytoplasm to vesicles.
(3) The Na+ ionophore, gramicidin, had a small but significant inhibitory effect on Na(+)-dependent KG uptake, demonstrating that KG uptake was not the result of an intravesicular positive Na+ diffusion potential.
(4) Omission of K(+), Ca(++) or Mg(++) had no effect on uptake.
(5) Because cystine in medium was converted rapidly to cysteine and cysteinyl-NAC in the presence of NAC and given that cysteine has a higher affinity for uptake by EC than cystine, we conclude that the enhanced uptake of radioactivity was in the form of cysteine and at least part of the stimulatory effect of NAC on EC glutathione was due to a formation of cysteine by a mixed disulfide reaction of NAC with cystine similar to that previously reported for Chinese hamster ovarian cells (R. D. Issels et al.
(6) Manometric studies with resting cells obtained by growth on each of these sulfur sources yielded net oxygen uptake for all substrates except sulfite and dithionate.

(13) Prolonged immobilization was accompanied by a decrease in Ca-concentration dependence of Ca2+ uptake.
(14) Inhibition of thymidine uptake is attributed to an observed decrease in thymidine kinase activity caused by growth in 1 mM dibutyryl cyclic AMP, and possibly to a simultaneous alteration in membrane permeability.
