Chick
Definition:
(v. i.) To sprout, as seed in the ground; to vegetate.
(n.) A chicken.
(n.) A child or young person; -- a term of endearment.
Example Sentences:
(1) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(2) In the stage 24 chick embryo, a paced increase in heart rate reduces stroke volume, presumably by rate-dependent decrease in passive filling.
(3) The in vivo approach consisted of interspecies grafting between quail and chick embryos.
(4) Whole-virus vaccines prepared by Merck Sharp and Dohme (West Point, Pa.) and Merrell-National Laboratories (Cincinnati, Ohio) and subunit vaccines prepared by Parke, Davis and Company (Detroit, Mich.) and Wyeth Laboratories (Philadelphia, Pa.) were given intramuscularly in concentrations of 800, 400, or 200 chick cell-agglutinating units per dose.
(5) The chick chorioallantoic membrane (CAM) model was used to study vascular effects of photodynamic therapy (PDT) and hyperthermia (HPT) and the synergism of these modalities.
(6) This study examines the morphology of sporadic congenital microphthalmia in 1-day-old chicks, with particular emphasis on the neural retina.
(7) Kidney DAAO activity was significantly higher in chicks fed either the DL-AA or .5 DL-AA diet as compared with the L-AA diet.
(8) By 3 d in the chick embryo, the first neurons detected by antibodies to Ng-CAM are located in the ventral neural tube; these precursors of motor neurons emit well-stained fibers to the periphery.

(12) In contrast, in paraffin as well as in frozen sections of chick oviduct, fixed by immersion or in vapor, PR was exclusively nuclear, including in the absence of progesterone, and the intensity of immunostaining was not modified by progesterone treatment.
