Example Sentences:
(1) Comprehending the nature of this property which couples ionic fluxions into mentality is the quintessential problem of science.

(3) The first equivalent of cobalt(II) ions per dimer binds in an essentially unspecific and possibly fluxional fashion, giving rise to a six-coordinated chromophore.
(4) A more exact time sequence cannot be established due to fluxional transitions and, particularly, to marked individual veriations.
(5) Electronic and 1H NMR titration with Co2+ ions show that the initial amount of fluxional cobalt is smaller than in the absence of magnesium and that A-B pairs are more readily formed.
(6) This asymmetry is not detected in solution by proton NMR spectroscopy at room temperature; however, at -90 degrees C spectroscopic changes suggest slowing of a fluxional process.
(7) We suggest that the Gd(DTPA)-conjugate systems have a fluxional coordination sphere whereby the amount of inner-sphere coordinated water varies from near zero at 5 degrees C to a high of two near 37 degrees C.
Rearrangement
Definition:
(n.) The act of rearranging, or the state of being rearranged.
Example Sentences:
(1) The process of sequence rearrangement appears to be a significant part of the evolution of the genome and may have a much greater effect on the evolution of the phenotype than sequence alteration by base substitution.
(2) The second amino acid residue influences not only the rate of reaction but also the extent of formation of the product of the Amadori rearrangement, the ketoamine.
(3) Our Ph1-positive ALL revealed B-cell lineage leukemia, since their surface phenotype were Ia+ and CD10+ and they have rearranged immunoglobulin JH genes.
(4) Nucleotide, which is essential for catalysis, greatly enhances the binding of IpOHA by the reductoisomerase, with NADPH (normally present during the enzyme's rearrangement step, i.e., conversion of a beta-keto acid into an alpha-keto acid, in either the forward or reverse physiological reactions) being more effective than NADP.
(5) Preliminary data also suggest that high-molecular-weight rearrangements of the duplicated region are present in all tissues.
(6) The combined evidence from immunoglobulin light chain staining and the analysis of immunoglobulin heavy chain gene rearrangement indicated that the lesions in most patients represented polyclonal proliferations that gave rise to clonal subpopulations.
(7) Cytoplasmic organelles were displaced and rearranged in the presence of somal neurofibrillary changes.
(8) Some abnormalities are found only in myeloid malignancies, for example, the t(8;21)(q22;q22) and rearrangements of chromosome 16q22, both of which have a good prognosis.
(9) The results showed that twenty-eight bands were significantly rearranged (P less than 0.05).
(10) No evidence for EGF receptor gene rearrangements was found at the level of DNA or RNA structure.
(11) Both diaminobutyric and diaminopropionic acids were seen in the acid hydrolyzate of the protein treated with hydroxylamine and subjected to rearrangement in the presence of carbodiimide.
(12) We suggest that radiation-induced specific chromosome 2 rearrangement associated with IL-1 beta deregulation may initiate murine leukemogenesis through the uncoupling of normal proliferative control mechanisms in multipotential hemopoietic cells.
(13) A 39-year-old male with follicular non-Hodgkin's lymphoma was repeatedly studied with respect to DNA rearrangements with the two probes pFL-1 and pFL-2, representing two segments of chromosome 18.
(14) In these lines a new V gene (V-lambda-X), exhibiting less than 60% homology to any known lambda or kappa V gene, is rearranged to J-lambda-2.
(15) A radical rearrangement of the organism occurred gradually: initially oval in shape, the parasite became round, then elongated, flattened, and underwent cytokinesis.
(16) In the absence of added ligands, membrane lipids did not appear to undergo a detectable temperature-dependent rearrangement or structural transition.
(17) Although its sensitivity is currently less than optimal, PCR is a rapid and practical screening method for the detection of IgH gene rearrangements.
(18) The lymphoid origin of these latter cases was proven by gene rearrangement studies.
(19) Together these rearrangements occur at about 10% the rate of IS10 transposition.
(20) TdT determination indicate would the presence of immature cells that are not detected in the normal lymphnode; molecular analysis of the rearrangements of these genes would reveal the presence of even a small monoclonal population of both T and B lineages in the lymphnodes.
