What's the difference between apparent and spontaneous?

Apparent


Definition:

  • (a.) Capable of being seen, or easily seen; open to view; visible to the eye; within sight or view.
  • (a.) Clear or manifest to the understanding; plain; evident; obvious; known; palpable; indubitable.
  • (a.) Appearing to the eye or mind (distinguished from, but not necessarily opposed to, true or real); seeming; as the apparent motion or diameter of the sun.
  • (n.) An heir apparent.

Example Sentences:

  • (9) Release of 51Cr was apparently a function of immune thymus-derived lymphocytes (T cells) because it was abrogated by prior incubation of spleen cells with anti-thymus antiserum and complement but was undiminished by passage of spleen cells through nylon-wool columns.

  • (15) We present a mathematical model that is suitable to reconcile this apparent contradiction in the interpretation of the epidemiological data: the observed parallel time series for the spread of AIDS in groups with different risk of infection can be realized by computer simulation, if one assumes that the outbreak of full-blown AIDS only occurs if HIV and a certain infectious coagent (cofactor) CO are present.
  • (16) Pedigree studies have suggested that there may be an inherited predisposition to many apparently nonfamilial colorectal cancers and a genetic model of tumorigenesis in common colorectal cancer has been proposed that includes the activation of dominantly acting oncogenes and the inactivation of growth suppressor genes.
  • (17) At 100 microM-ACh the apparent open time became shorter probably due to channel blockade by ACh molecules.
  • (18) For SP and NKA the decrease was apparent in all brain regions and both in the right and left hemispheres.

  • (20) The authors examined an eye obtained post-mortem from a patient with chronic granulomatous disease of childhood and clinically apparent chorioretinal scars.

Spontaneous


Definition:

  • (a.) Proceding from natural feeling, temperament, or disposition, or from a native internal proneness, readiness, or tendency, without constraint; as, a spontaneous gift or proportion.
  • (a.) Proceeding from, or acting by, internal impulse, energy, or natural law, without external force; as, spontaneous motion; spontaneous growth.
  • (a.) Produced without being planted, or without human labor; as, a spontaneous growth of wood.

Example Sentences:

  • (1) Spectral analysis of spontaneous heart rate fluctuations, a powerful noninvasive tool for quantifying autonomic nervous system activity, was assessed in Xenopus Laevis, intact or spinalized, at different temperatures and by use of pharmacological tools.

  • (4) administration of the potent short-acting opioid, fentanyl, elicited inhibition of rhythmic spontaneous reflex increases in vesical pressure (VP) evoked by urinary bladder distension.
  • (5) Sample processing appears effective in avoiding spontaneous oxalogenesis.
  • (6) Thus, B cells that grow spontaneously from the peripheral blood of SS patients spontaneously produce a B-cell growth factor.
  • (7) They can rarely be detected spontaneously but most often are provoked.
  • (8) The ACTH deficiency recovered spontaneously, with normal cortisol responses to depot Synacthen (greater than 1380 at 6 h) and hypoglycemia (peak, 590) 14 and 18 months postpartum, respectively.
  • (9) The number of peripheral blood lymphocytes (PBL) producing IgM (spontaneous and pokeweed mitogen (PWM) stimulated) at the end of a seven day culture period was similar in PBC patients and control subjects while the amount of IgM synthesized (spontaneous and PWM stimulated) during this period was significantly greater in the patient group, implying that the amount of IgM produced per B cell was increased in PBC.
  • (10) In in vitro preparations GABA (10(-7) - 10(-3) M) elicited a dose-dependent relaxation; a decrease in the spontaneous contractions was sometimes observed.
