In one clinical study benign and malignant lesions with similar distributions of MVD on histology could not be distinguished on the basis of contrast enhancement, although the amplitude, but not the rate, of contrast enhancement correlated with MVD.
On the basis of the enhancement effect of the composite film, energy transfer between upconversion nanoparticles (UCNPs) and quantum dots (QDs), and the sensitive sensing of CdTe QDs on mercury, the UC composite film was used for sensing of Hg2+ in serum.
Open image in new window Fig. 1 Schematic illustration of the detection of Fe3+ on the basis of fluorescence enhancement and subsequently fluorescence quenching.
Further elucidation of the molecular basis of CT enhancement of japonica rice arising from introgression of favorable alleles from indica rice would provide rice breeders with much useful information.
Refinements in pharmacokinetic modelling analyses will allow an understanding of the physiological basis of contrast enhancement and such techniques are likely to be incorporated into imaging assessments of cancer patients.
Thus we also explicitly included images of limited quality, e.g. on the basis of suboptimal enhancement or breathing artefacts.
These data are collected with the intention of setting down the basis for the enhancement of a progressive collapse analysis, that is, by the way, a dynamic event.
What is the molecular basis for such enhancement of cellulase activity?
Engineered receptor fragments and glycoprotein ligands employed in different assay formats have been used to dissect the basis for the dramatic enhancement of binding of two model membrane receptors, dendritic cell-specific intercellular adhesion molecule 3-grabbing nonintegrin (DC-SIGN) and the macrophage galactose lectin, to glycoprotein ligands compared to simple sugars.
