What's the difference between accumulation and ascertaining?

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.

  • (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.

  • (8) It was also shown that after a shock at 44 degrees C teratocarcinoma cells were able to accumulate anomalous amounts of hsp 70 despite hsp 70 synthesis inhibition.
  • (9) At 24 or 48 hours after ischemia, 63Ni, 99TcO4, and 22Na were preferentially concentrated in the damaged striatum and hippocampus, whereas 65Zn, 59Fe, 32PO4, and 147Pm did not accumulate in irreversibly injured tissue.
  • (10) Aside from these characteristic findings of HCC, it was important to reveal the following features for the diagnosis of well differentiated type of small HCC: variable thickening or distortion of trabecular structure in association with nuclear crowding, acinar formation, selective cytoplasmic accumulation of Mallory bodies, nuclear abnormalities consisting of thickening of nucleolus, hepatic cords in close contact with bile ducts or blood vessels, and hepatocytes growing in a fibrous environment.
  • (11) They are capable of synthesis and accumulation of glycogen and responsible for its transfer to sites of more intense metabolism (growth, bud, blastema).
  • (12) Our results show that large complex lipid bodies and extensive accumulations of glycogen are valuable indicators of a functionally suppressed chief cell in atrophic parathyroid glands.
  • (13) Much information has accumulated on the isolation and characterization of a heterogeneous group of molecules that inhibit one or more of the bioactivities of interleukin 1.
  • (14) The mechanism by which K+ accumulates in the follicle was insensitive to ouabain, so that a typical Na+, K(+)-ATPase mechanism does not appear to be involved.
  • (15) The data shows a dissociation between ferritin synthesis, cellular accumulation and secretion for which the mechanisms have still to be elucidated.
  • (16) The rate of accumulation was highest late in infection and only the slower migrating form incorporates significant amounts of glucosamine.
  • (17) Initiation of the alternative pathway by the cryptococcal capsule is characterized by a lag in C3 accumulation and the appearance of a limited number of focal initiation sites which resemble those observed when the alternative pathway is activated by zymosan and nonencapsulated cryptococci.
  • (18) Accumulating evidence indicates that for most tumors, the switch to the angiogenic phenotype depends upon the outcome of a balance between angiogenic stimulators and angiogenic inhibitors, both of which may be produced by tumor cells and perhaps by certain host cells.
  • (19) The aim of our experiments was to investigate firstly whether during an acute inflammatory process platelets accumulate in the inflamed area and secondly whether the inflammation has an effect on the properties of the platelets.
  • (20) The accumulated evidence would strongly favor an affirmative answer.

Ascertaining

  • (3) A total of 13 ascertainments of folate sensitive autosomal fragile sites is observed, of which 10q23 fragility appears to be the most frequent.
  • (4) A similar examination of the effects of PD was also carried out in vitro to ascertain whether PD itself or its metabolites are involved in its action.
  • (5) The purity and configuration of each isomer of the free acid and N-chloroacetylated derivative were ascertained by: (a) paper chromatography in five solvent systems, (b) elemental analysis, (c) Van Slyke nitrous acid determination of alpha-carbonyl carbon, and (d) Van Slyke ninhydrin determination of alpha-carbonyl carbon, and (e) optical rotation.
  • (6) In an anthropologic study of illness referral among Latin-American immigrants three phases were ascertained: First, there was extended use of self-treatment.
  • (7) In 20 adult patients with asthma, we evaluated bronchodilation to a single administration of metered-dose glycopyrrolate aerosol (GA) to ascertain its onset and duration of action along with evaluation of safety.
