What's the difference between acidific and acidity?

Acidific


Definition:

  • (a.) Producing acidity; converting into an acid.

  • (11) In accord with this explanation cytoplasmic acidification by bicarbonate was antagonised by acetazolamide (an inhibitor of carbonic anhydrase).
  • (12) The effect of lithium chloride administration on urinary acidification was studied in dogs.
  • (13) When the endosomes were incubated in a chloride-containing buffer, degradation was greatly inhibited, and acidification did not occur.
  • (14) Acute acid loading stimulates endogenous PTH secretion, which, by enhancing urinary acidification, constitutes a homeostatic response of the parathyroid glands.
  • (15) Acidification is therefore necessary to establish the probability of translocation, but it is not directly involved in the actual translocation of these toxins.
  • (16) The pathophysiological mechanism of production appears to be the accumulation of acid ions caused by pH acidification of the cerebrospinal fluid.
  • (17) These results indicate that the candidacidal activity of gamma interferon-activated PMPs correlates well with enhanced acidification of their phagolysosomes and suggest that the candidacidal activity of activated PMPs is independent from reactive oxygen molecules and is mediated by proteinaceous substance(s) generated only in a strong acidic milieu of phagolysosomes by activation.
  • (18) Acidification of a meal stimulates somatostatin release in dogs.
  • (19) The acidification did not interfere in leukocyte migration under agar.
  • (20) Gastrin I did not significantly increase pyloric pressure but did antagonize the pyloric response to duodenal acidification.

Acidity


Definition:

  • (n.) The quality of being sour; sourness; tartness; sharpness to the taste; as, the acidity of lemon juice.

Example Sentences:

  • (1) The amino acid sequence deduced from the nucleotide sequence contained both amino- and carboxyl-terminal sequences.
  • (2) F(420) is photolabile aerobically in neutral and basic solutions, whereas the acid-stable chromophore is not photolabile under these conditions.
  • (3) The high amino acid levels in the cells suggest that these cells act as inter-organ transporters and reservoirs of amino acids, they have a different role in their handling and metabolism from those of mammals.
  • (4) If ascorbic acid was omitted from the culture medium, the extensive new connective tissue matrix was not produced.

  • (6) Arachidic acid was without effect, while linoleic acid and linolenic acid were (on a concentration basis) at least 5-times less active than arachidonic acid.
  • (7) An unsaturated fatty acid auxotroph of Escherichia coli was grown with a series of cis-octadecenoate isomers in which the location of the double bond varied from positions 3 to 17.
  • (8) The ability of azelastine to influence antigen-induced contractile responses (Schultz-Dale phenomenon) in isolated tracheal segments of the guinea-pig was investigated and compared with selected antiallergic drugs and inhibitors of arachidonic acid metabolism.
  • (9) After 4 to 6 hours of recirculation, accumulation of vasoactive amine, 5-hydroxytryptamine, its major metabolite, 5-hydroxyindole acetic acid, and its precursor amino acid, tryptophan were detected.
  • (10) Spectrophotometric determination of the sulfhydryl content in the animal tissue before (control) and after using 6,6'-Dithiodinicotinic acid is applied.

  • (12) However, four of ten young adult outer arm (relatively sun-exposed) and one of ten young adult inner arm (relatively sun-protected) fibroblasts lines increased their saturation density in response to retinoic acid.
  • (13) Microionophoretically applied excitatory amino acids induced firing of extracellularly recorded single units in a tissue slice preparation of the mouse cochlear nucleus, and the similarly applied antagonist 2-amino-5-phosphonovalerate (2APV) was demonstrated to be a selective N-methyl-D-aspartate (NMDA) receptor antagonist.
  • (14) The LD50 of the following metal-binding chelating drugs, EDTA, diethylenetriaminepentaacetic acid (DTPA), hydroxyethylenediaminetriacetic acid (HEDTA), cyclohexanediaminotetraacetic acid (CDTA) and triethylenetetraminehexaacetic acid (TTHA) was evaluated in terms of mortality in rats after intraperitoneal administration and was found to be in the order: CDTA greater than EDTA greater than DTPA greater than TTHA greater than HEDTA.
