What's the difference between binnacle and pyx?

Binnacle


Definition:

  • (n.) A case or box placed near the helmsman, containing the compass of a ship, and a light to show it at night.

Example Sentences:

  • (1) The binnacle protected the ship's metal compass and its coming home to Cardiff is the result of a long hard fight by Dr Peter Lloyd Jones and Michael Tarver, vice president of the Captain Scott Society.
  • (2) They told me a bit more about the binnacle in the video below.
  • (3) It is here visitors will get the chance to view the original binnacle from the Terra Nova ship which took Captain Scott and his team on their ill-fated voyage to Antarctica in 1910.

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.
