  • (15) The hypothesis of calcium-related cell damage is based on the fact that dense ischemia leads to an influx of calcium into cells, and that raised intracellular calcium concentrations activate lipases and proteases, and cause disaggregation of neurotubuli and enhanced protein phosphorylation.

  • (19) The results revealed that aflatoxin B1 rapidly led to disaggregation of free and membrane-bound polyribosomes, to inhibition of in vitro protein synthesis by both populations of polyribosomes, to little or no effect on the activities of initiation factors, and to defective ribosomes, particularly the 60S ribosomal subnits, of both types of polyribosomes.
  • (20) When developing cultures of Dictyostelium discoideum are disaggregated at any time prior to cell wall formation and challenged to reinitiate development, amoebae will progress through the original sequence of morphogenetic stages, but the second time through they will do so in roughly one-tenth the original time, a process known as 'rapid recapitulation'.

Segregation


Definition:

  • (n.) The act of segregating, or the state of being segregated; separation from others; a parting.
  • (n.) Separation from a mass, and gathering about centers or into cavities at hand through cohesive attraction or the crystallizing process.

Example Sentences:

  • (1) However, the average age at onset of lymphoma varied considerably among the different AKXD strains, suggesting that they have segregated several loci that affect lymphoma susceptibility.
  • (2) Both types of oral cleft, cleft palate (CP) and cleft lip with or without CP (CLP), segregate in these families together with lower lip pits or fistulae in an autosomal dominant mode with high penetrance estimated to be K = .89 and .99 by different methods.
  • (3) Reciprocal translocations involving the short arm of acrocentric chromosomes can segregate to produce partial duplications without associated deletions.
  • (4) Cellular responses in vitro to H-2D region histocompatibility antigens were demonstrated to be under the genetic control of two or three (P = 0.013) independently segregating loci.
  • (5) Recombination between markers was observed in matings between phage beta and the heteroimmune corynebacteriophages gamma and L. In such matings between heteroimmune phages the c markers of phages beta and gamma failed to segregate from the imm markers which determine the specificity of lysogenic immunity in these phages.
  • (6) For analytical purposes, irradiated dogs were segregated into groups according to their clinical status: clinically normal, hypocellular, or with acute non-lymphocytic leukemia.
  • (7) Interestingly, actinomycin D treatment dissociated centromeres from localization within the segregated nucleolus.
  • (8) In contrast, hybrids segregating human chromosomes contain both human and murine histone mRNAs, yet synthesize only mouse histone proteins.
  • (9) Models incorporating linear spatial-frequency- and orientation-selective channels explain many aspects of visual texture segregation.
  • (10) On the basis of segregating phenotypes, the genetic potentials of these compatible nocardiae were ascertained as follows: the formation of a diploid with subsequent segregation of parental or haploid recombinant genomes or both; persistence of the diploid through many generations; continuing reassortment of genetic information by multiple matings between parental or recombinant organisms; and, very probably, second-round recombinations within the diploid.
  • (11) The £77m, split between Manchester, Leeds, Birmingham, Newcastle, Bristol, Cambridge, Oxford and Norwich, will help improve existing cycle networks and pay for new ones, creating segregated routes in some areas.
