System gain and scaling factors were maintained between acquisition of the proton density and T1-weighted dynamic series of images to enable the calculation of tissue contrast agent concentration (Parker et al, 1997).
It has previously been reported that MCF-7 cells do not synthesize HRGs [ 45], and our findings now indicate that the inability to generate this ligand is maintained through acquisition of tamoxifen resistance in this cell line.
While the legacy hard disk drive juggernauts strive to maintain relevance through acquisition of major SSD players like SanDisk and LSI, Toshiba's roots as the inventor of NAND Flash for SSDs and have afforded the company a natural, long term soup-to-nuts play in both spinning and solid state storage that is beginning to pay off.

From these observations, we can hardly conclude that the multiple PDE1Cb genes were maintained through the acquisition of new enzyme functions.
This pattern of purifying and positive selection suggests that after Hox cluster duplications, selection acted on protein-protein interaction sites in such a way that ancestral functions were maintained while the acquisition of novel protein interaction partners driven was driven by selection on non-constrained amino acids.
The high frame rate can reduce the total data acquisition time, while maintaining data acquisition volume.
In a lawsuit filed last month to block the deal, the F.T.C. and the three states on the West Coast maintained that BP Amoco's acquisition of ARCO was anticompetitive and violated the Clayton Antitrust Act.
