Pyx


Definition:

  • (n.) The box, case, vase, or tabernacle, in which the host is reserved.
  • (n.) A box used in the British mint as a place of deposit for certain sample coins taken for a trial of the weight and fineness of metal before it is sent from the mint.
  • (n.) The box in which the compass is suspended; the binnacle.
  • (n.) Same as Pyxis.
  • (v. t.) To test as to weight and fineness, as the coins deposited in the pyx.

Example Sentences:

  • (1) The amino acid sequence of the active center hexapeptide has been determined to be: H2NLys(Pyx)Pro-Gly-Met-Thr-Arg-COOH.
  • (2) After PVN injection of PYX-2 (50-900 pmoles) alone, a strong dose-dependent reduction in spontaneous carbohydrate intake at the onset of the dark cycle was observed in freely-feeding rats.
  • (3) This study examined the behavioral effects of a newly synthesized NPY antagonist, PYX-2.
  • (4) After screening a series of mixtures of NPY analogs by using an NPY antagonist assay, two potent receptor antagonists, designated PYX-1 and PYX-2, were isolated from an antagonist-containing mixture.
  • (5) Amino acid analysis of the peptide demonstrated the presence of N6-pyridoxyl-L-lysine (Lys(Pyx)), establishing the existence of an essential lysing residue in the active center of malate dehydrogenase.
  • (6) Moreover, at even lower doses (12.5 and 25.0 pmoles), PYX-2 also blocked the stimulatory action of PVN NPY (100 pmoles) on carbohydrate ingestion.
  • (7) Chronic conditioning by the NPY antagonist PYX-2 blocked the effect of innervation.

Sample


Definition:

  • (n.) Example; pattern.
  • (n.) A part of anything presented for inspection, or shown as evidence of the quality of the whole; a specimen; as, goods are often purchased by samples.
  • (v. t.) To make or show something similar to; to match.
  • (v. t.) To take or to test a sample or samples of; as, to sample sugar, teas, wools, cloths.
