Pedicle


Definition:

  • (n.) Same as Pedicel.

Substrate


Definition:

  • (n.) A substratum.
  • (a.) Having very slight furrows.
  • (v. t.) To strew or lay under anything.

Example Sentences:

  • (1) 5-HT thus appears to be the preferred substrate for uptake into platelets and for movement from cytoplasm to vesicles.
  • (2) Some common eye movement deficits, and concepts such as 'the neural integrator' and the 'velocity storage mechanism', for which anatomical substrates are still sought, are introduced.
  • (3) These results demonstrate that increased availability of galactose, a high-affinity substrate for the enzyme, leads to increased aldose reductase messenger RNA, which suggests a role for aldose reductase in sugar metabolism in the lens.
  • (4) The common polyamines, spermidine and spermine, and histones were not substrates.
  • (5) 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.
  • (6) The PSB dioxygenase system displayed a narrow substrate range: none of 18 sulphonated or non-sulphonated analogues of PSB showed significant substrate-dependent O2 uptake.
  • (7) The observed relationship between prorenin and renin substrate concentrations might be a consequence of their regulation by common factors.
  • (8) This theory was confirmed by product analysis and by measuring the affinity of the substrate for the enzyme by its inhibition of p-nitrophenyl glucoside hydrolysis.
  • (9) Yields of Thiobacillus dentrificans on different substrates were compared.
  • (10) It includes preincubation of diluted plasma with ellagic acid and phospholipids and a starting reagent that contains calcium and a chromogenic peptide substrate for thrombin, Tos-Gly-Pro-Arg-pNA.
  • (11) The present results provide no evidence for a clear morphological substrate for electrotonic transmission in the somatic efferent portion of the primate oculomotor nucleus.
  • (12) Fluorination with [18F]acetylhypofluorite yields 6-[18F]fluoro-L-dopa with 95% radiochemical purity; fluorination of the same substrate with [18F]F2 yields a mixture of all three structural isomers in a ratio of 70:16:14 for 6-, 5-, and 2-fluoro compounds.
  • (13) The enzyme, when assayed as either a phospholipase A2 or lysophospholipase, exhibited nonlinear kinetics beyond 1-2 min despite low substrate conversion.
