  • (v. t.) To offer, as violence.
  • (v. t.) To bring forward, or employ as an argument; to adduce; to allege; to offer.
  • (v. t.) To derive by deduction or by induction; to conclude or surmise from facts or premises; to accept or derive, as a consequence, conclusion, or probability; to imply; as, I inferred his determination from his silence.
  • (v. t.) To show; to manifest; to prove.

Example Sentences:

  • (16) Tonic sympathetic neural control of heart rate was inferred from bradycardia after treatment with the adrenergic neuron-blocking agent, bretylium tosylate.
  • (17) Two consequences of these conditions are (1) patient classification into syndrome types (e.g., phonological dysgraphia, agrammatism, and so forth) can play no useful role in research concerned with issues about the structure of normal cognitive functioning or its dissolution under conditions of brain damage; and (2) only single-patient studies allow valid inferences about the structure of cognitive mechanisms from the analysis of impaired performance.
  • (18) Results are discussed and inferences for better care, particularly of the mentally ill residents, are indicated.
  • (19) By way of conclusion, from our observations we may infer that neither age, nor sex nor location, save in the case of patients under the age of 40, have prognostic value in the evolution of the primary tumor, which will be noticeably better (lower percentage of relapses and longer illness-free period) in patients with a single tumor of low grade and state, and in general in patients receiving intravesical prophylactic chemotherapy treatment, and no difference is found between thio-tepa and adriamycin.
  • (20) Awareness of making dispositional inferences was only weakly correlated with disposition-cued recall.

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.
  • (4) Trichostatin C is presumably the first example of a glucopyranosyl hydroxamate from nature.
  • (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].

  • (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.
  • (14) In the terminal segment of the hamster epididymidis there was some evidence of micro-merocrine protein secretion a the level of the principal cells and clear evidence of granular secretion in the light cells, presumable of glycoproteins.
