What's the difference between accretion and accumulation?

Accretion


Definition:

  • (n.) The act of increasing by natural growth; esp. the increase of organic bodies by the internal accession of parts; organic growth.
  • (n.) The act of increasing, or the matter added, by an accession of parts externally; an extraneous addition; as, an accretion of earth.
  • (n.) Concretion; coherence of separate particles; as, the accretion of particles so as to form a solid mass.
  • (n.) A growing together of parts naturally separate, as of the fingers toes.
  • (n.) The adhering of property to something else, by which the owner of one thing becomes possessed of a right to another; generally, gain of land by the washing up of sand or sail from the sea or a river, or by a gradual recession of the water from the usual watermark.
  • (n.) Gain to an heir or legatee, failure of a coheir to the same succession, or a co-legatee of the same thing, to take his share.

Accumulation


Definition:

  • (n.) The act of accumulating, the state of being accumulated, or that which is accumulated; as, an accumulation of earth, of sand, of evils, of wealth, of honors.
  • (n.) The concurrence of several titles to the same proof.

Example Sentences:

  • (1) The accumulation of lipids and enzymes such as simple estarase, lipase, beta-HDH, alpha-GDH and NADPH-reductase in those areas, suggests that lipids are not a simple excretory product.
  • (2) 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.
  • (3) The rate of accumulation of degraded LDL products was lower in collagen gel cultures, but the final levels achieved were the same in the two substrata.
  • (4) Based on several previous studies, which demonstrated that sorbitol accumulation in human red blood cells (RBCs) was a function of ambient glucose concentrations, either in vitro or in vivo, our investigations were conducted to determine if RBC sorbitol accumulation would correlate with sorbitol accumulation in lens and nerve tissue of diabetic rats; the effect of sorbinil in reducing sorbitol levels in lens and nerve tissue of diabetic rats would be reflected by changes in RBC sorbitol; and sorbinil would reduce RBC sorbitol in diabetic man.
  • (5) These effects are similar to those reported for AVP and phorbol esters, activators of protein kinase C. Forskolin and isoproterenol, which induce cAMP accumulation, activated extractable topoisomerase II (maximum 5-15 min after treatment), but not topoisomerase I. Permeable cyclic nucleotide analogs dBcAMP and 8BrcGMP selectively activated extractable topoisomerase II and topoisomerase I activities, respectively.
  • (6) The data support the conclusion that accumulation of lipid II is responsible in some way for the hypersensitivity of delta rfbA mutants to SDS.
  • (7) In addition, the guanosine 3',5'-cyclic monophosphate accumulation response was less impressive in glomeruli than the guanylate cyclase response in IMCD tissue.
