  • (n.) A chicken.
  • (n.) A child or young person; -- a term of endearment.

Example Sentences:

  • (10) Chick sympathetic nerve fibers densely innervate expansor secundariorum muscle, but not skeletal muscle.
  • (11) The onset of vitamin A deficiency had no effect on oviduct growth in these chicks; even though vitamin A-deficient chicks showed a severe decline in growth rate while controls (fed the same diet supplemented with retinyl palmitate) continued to grow, estrogen stimulated resulted in similar oviduct size.
  • (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.
  • (13) Two mechanisms are evident in chicks' spatial representations: a metric frame for encoding the spatial arrangement of surfaces as surfaces and a cue-guidance system for encoding conspicuous landmarks near the target.

  • (16) Dissociated cerebral hemisphere cells from 4- to 7-day-old chick embryos were cultured either on a collagen or a polylysine substrate in a serum-containing medium.
  • (17) In the present study, we have compared the phosphorylation state of the fibronectin receptor in motile neural crest and somitic cells, in stationary somitic cells, and in Rous-sarcoma virus transformed-chick embryo fibroblasts, using immunoprecipitation following metabolic labeling.
  • (18) The myogenic potential of chick limb mesenchyme from stages 18-25 was assessed by micromass culture under conditions conductive to myogenesis, and was measured as the proportion of differentiated (muscle myosin-positive) mononucleated cells detected.
  • (19) Both the formazans and tetrazolium salts were screened for their antiviral activity against the Ranikhet disease virus and vaccinia virus in a stationary culture of chorioallantoic membrane of chick embryo.
  • (20) Studies have been made on the activity of glycosidases from eye tissues of developing chick embryos and adult hens.

Hen


Definition:

  • (n.) The female of the domestic fowl; also, the female of grouse, pheasants, or any kind of birds; as, the heath hen; the gray hen.

Example Sentences:

  • (1) Whether hen's egg yolk can be used as a sperm motility stimulant in the treatment of such conditions as asthenospermia and oligospermia is subjected for further study.
  • (2) Studies were conducted to evaluate the effects of acute (24 h) thermal stress on anterior pituitary function in hens.
  • (3) Lead levels in contents and shells of eggs laid by hens dosed with all-lead shot were about twice those in eggs laid by hens dosed with lead-iron shot.
  • (4) Unlike most birds of prey, which are territorial and fight each other over nesting and hunting grounds, the hen harrier nests close to other harriers.
  • (5) In Experiment 1 (summer), hens regained body weight more rapidly, returned to production faster, and had larger egg weights (Weeks 1 to 4) when fed the 16 or 13% CP molt diets than when fed the 10% CP molt diet.
  • (6) Studies have been made on the activity of glycosidases from eye tissues of developing chick embryos and adult hens.

  • (8) Each diet was fed to five or six individually caged hens for 42 days.
  • (9) Mortality was less in the N-XL as compared to DB, but NB hens showed 11.7% more mortality than dwarfs.
  • (10) Raw Target RSM was force fed to 12 hens which were killed after varying time intervals (15 min., 30 min., 60 min.)
  • (11) A reduction in tibial breaking strength was also found in caged hens, when compared to deep-litter hens.
  • (12) To investigate the physical state of water in hydrating biological macro-molecules, the dielectric properties of water in hen egg lysozyme pellets with various moisture contents were studied using the thermally stimulated depolarisation currents technique.
