What's the difference between postulate and presume?

Postulate


Definition:

  • (n.) Something demanded or asserted; especially, a position or supposition assumed without proof, or one which is considered as self-evident; a truth to which assent may be demanded or challenged, without argument or evidence.
  • (n.) The enunciation of a self-evident problem, in distinction from an axiom, which is the enunciation of a self-evident theorem.
  • (a.) Postulated.
  • (v. t.) To beg, or assume without proof; as, to postulate conclusions.
  • (v. t.) To take without express consent; to assume.
  • (v. t.) To invite earnestly; to solicit.

  • (20) More than 20 years ago Olney and his colleagues described the 'Excitotoxic Hypothesis' which postulates that, in addition to its normal function in the healthy brain, glutamate can kill neurons by prolonged, receptor-mediated depolarization resulting in irreversible disturbances in ion homeostasis.

Presume


Definition:

  • (v. t.) To assume or take beforehand; esp., to do or undertake without leave or authority previously obtained.
  • (v. t.) To take or suppose to be true, or entitled to belief, without examination or proof, or on the strength of probability; to take for granted; to infer; to suppose.
  • (v. i.) To suppose or assume something to be, or to be true, on grounds deemed valid, though not amounting to proof; to believe by anticipation; to infer; as, we may presume too far.
  • (v. i.) To venture, go, or act, by an assumption of leave or authority not granted; to go beyond what is warranted by the circumstances of the case; to venture beyond license; to take liberties; -- often with on or upon before the ground of confidence.

Example Sentences:

  • (1) With aging, the blood vessel wall becomes hyperreactive--presumably because of an augmented vasoconstrictor and a reduced vasodilator responsiveness.
  • (2) Four of the 39 ticks in our colony were infected with a spirochete; presumably, Borrelia crocidurae.
  • (3) In the stage 24 chick embryo, a paced increase in heart rate reduces stroke volume, presumably by rate-dependent decrease in passive filling.

  • (5) 3) The first who presumed an independent state of these microorganisms, was Kohlert (1968), from the work of which the epithet for correct name, i.e.
  • (6) Recently, we have designed a series of simplified artificial signal sequences and have shown that a proline residue in the signal sequence plays an important role in the secretion of human lysozyme in yeast, presumably by altering the conformation of the signal sequence [Yamamoto, Y., Taniyama, Y., & Kikuchi, M. (1989) Biochemistry 28, 2728-2732].
  • (7) Though three of these presumable metabolites could slightly inhibit the binding of [3H]-KW-3049, they were not detected in rat and dog plasma at 0.5 h after oral administration of KW-3049.
  • (8) However, since CR3 does not recognize a hexapeptide containing RGD, we presume that residues beyond the RGD triplet contribute to binding.
  • (9) Since alkaline phosphatase, a glycoprotein, is not affected, the destruction is selective and presumably involves only the most exposed membrane components.
  • (10) Eighty four colorectal cancer patients who underwent presumably curative surgery were considered as candidates for control recurrence study.
  • (11) 5% of the degradation resulted from enzymatic activity in the culture medium, presumably due to secretion of proteolytic enzymes by the cells.
  • (12) The larger accumulation of Mn2+ than of Sr2+ in Saccharomyces cerevisiae is ascribed to the operation of a specific extrusion pump, presumably a Ca2+ pump, which has a higher affinity for Sr2+ than for Mn2+.
  • (13) Altering the time of PMA exposure demonstrated that PMA inhibited chondrocyte phenotypic expression, rather than cell commitment: early (0-48 h) exposure to PMA (during chondrocytic commitment in vitro) had little inhibitory effect on the staining index, whereas, exposure from 49-96 h (presumably post-commitment) and 0-96 h had moderate and strong inhibitory effects, respectively, on cartilage synthesis.
