What's the difference between coalescence and concrescence?

Coalescence


Definition:

  • (n.) The act or state of growing together, as similar parts; the act of uniting by natural affinity or attraction; the state of being united; union; concretion.

Example Sentences:

  • (1) Above 160 K, the line position in Mb* shifts again and coalesces with the value of Mb for temperatures above 200 K. The shift is accompanied by an increase of the line area, reflecting a slowing of rebinding kinetics.
  • (2) Thus when the implant consisted of compound cranial half-somites, giant, coalesced ganglia developed, encompassing the entire length of the graft.
  • (3) Enlargement and coalescence of intercellular spaces gave rise to intertrabecular channels.
  • (4) Light and electron microscopic examination of the central and peripheral nervous systems showed that intramyelinic vacuolation developed in the white matter of brain and cord within 12 h. The intramyelinic vacuolation in the white matter of brain and cord became more severe with longer survival, vacuoles coalescing and secondary axonal degeneration becoming evident.
  • (5) Chemical dehydration with 2,2-dimethoxypropane was used to convert an albumin emulsion into an albumin suspension and to reduce coalescence.
  • (6) Scanning electron microscopic studies of myoblasts from 11- to 13-day-old chick embroyonic breast muscle cultured on collagen-coated glass coverslips showed six stages of development into multinucleated myotubes: (1) growth of flattened, spread-out cells for 20-30 hr following initiation of monolayer cultures; (2) extension of microprocesses (1-150 microM) from cells that have become spindle shaped; (3) contact and adherence of microprocesses from adjacent cells; (4) thickening of fused processes; (5) approximation of the cells; and (6) coalescence of the cells to form a spindle-shaped myotube.
  • (7) The author describes the experiences, the series of "apprenticeships" and clinical exposures, which coalesced into his education, from teenage days in the New York Madison House settlement, through Harvard undergraduate and graduate work, to Worcester State Hospital as head of psychological services and research.
  • (8) Very young parasites lack the pigment but deposits of pigment appear and coalesce into dense deposits within the parasite as it grows.
  • (9) These occured as small beaded and larger coalescent masses which varied in metachromasia.
  • (10) The focal adhesions which are typical of the spread chick RPE cells in vitro consist of several closely apposed focal contacts, arranged in a parallel fashion, which are often coalesced with each other along their sides.
  • (11) The lesion begins with cytoplasmic vacuolar degeneration of the arterial smooth-muscle cells, which then progresses to coalescence of vacuoles, leading to disruption of the media, intramural hemorrhage, and periadventitial fibrin deposition.
  • (12) Four months postbiopsy the patient is asymptomatic but with the coalesced white plaques remaining.
  • (13) In 10- and 16-day grafts, continuity between ventricular and graft lumina was established and coalescence of graft pieces was apparent.
  • (14) These lesions, which may be smaller but often are larger than the iris lesions in conventional erythema multiforme, tend to coalesce into plaques and reveal a papulovesicular component at their periphery.
  • (15) Computed tomographic findings suggest the tumor begins as multiple hepatic nodules that grow and coalesce, forming large confluent masses preferentially involving the liver periphery.
  • (16) These findings, supported by simulation results, allow one to apply the theoretical results of the coalescence process directly to the allelic genealogy.
  • (17) This arose by the formation of large glycogen lakes, which coalesced and then lost their glycogen content, and this was accompanied by nuclear irregularity and shrinkage.
  • (18) Oil bodies isolated from mature maize (Zea mays) embryos maintained their discreteness, but coalesced after treatment with trypsin but not with phospholipase A2 or C. Phospholipase A2 or C exerted its activity on oil bodies only after the exposed portion of oleosins had been removed by trypsin.
  • (19) The ring-shaped elements of the RV and the moderately electron-dense material of the MDV were released exocytotically somewhat later; these materials coalesced in the perivitelline space to form a new coat (envelope 2).
  • (20) Following heated public debate over the issue of top-slicing the BBC licence fee, opinion at the broadcasters and the Department for Culture, Media and Sport is now coalescing around a less overt method of the corporation helping with Channel 4's future funding needs.

Concrescence


Definition:

  • (n.) Coalescence of particles; growth; increase by the addition of particles.

Example Sentences:

  • (1) Concrescence irrespective of localization rarely creates a pathological neurological situation.
  • (2) This pathology was expressed in the form of concrescence in 66 cases (61.6%) and in the form of assimilation--in 41 cases (38.3%).
  • (3) In the part of nucellus concrescent with the integument, the mitotic activity disappears still prior to fertilization and the growth proceeds, mainly, at the expense of cell elongation.
  • (4) An unusual collision tumour (concrescence of two neighbouring independent neoplasms) is reported.
  • (5) Less frequent was a fusion of the atlant with the occipital bone in the form of assimilation, (in 27 cases), concrescense (in 4 cases), and significantly less frequent a fusion of the atlant with the axis (in 3 cases in the form of assimilation, in 1 case in the form of concrescence).
  • (6) This paper describes the impossibility of assigning precise diagnostic terms, such as germination, fusion, macrodontia, and concrescence, to dental twinning anomalies because the entire course of odontogenesis cannot be witnessed.
  • (7) Two instances of laparotomy for heavy abdominal bleeding revealed peritoneal thickening, laminar intestinal concrescence and diffuse haemorrhage.
