While acknowledging that "the politics are risky," he said it was "a defining time in politics, where you know the facts are on your side".
Three different PEDOT composites (PEDOT Cl, PEDOT:Heparin and PEDOT:DBS) were produced by electropolymerization, applying an electrical current for a defined time in specific polymerization solutions.
But even the gradualists now seem to acknowledge that the end should come at a defined time in the very near future, rather than in the foggy realm of someday when we're all nicer.
In this instance the trade-off occurred between the two alternatives being dead and spending a defined time in a particular health state followed by a period of full health.
Since qRT-PCR allows the quantification of a given transcript at a defined time (in this case, 3 hours), the other genes identified by R-IVET screening and not confirmed by qRT-PCR might be induced at another moment during urine exposure.
The damaged edifice no longer keeps time, but it marks a defining time, still standing tall in the midst of rubble and ruin.
While a recent study by Garcia-Martinez et al. [ 15] in yeast using a similar approach demonstrated large shifts in mRNA stability following a glucose-to-galactose shift, the work presented here is the first systematic accounting of the changes in both gene transcription and mRNA stability in response to a major cellular activation event over a defined time period in higher eukaryotes.
This was demonstrated either by the difference of the maximum current intensity of isopropanol oxidation measured in cyclic voltammograms, or by the different variation of the intensity of specified ir band with potential for species produced within a defined time window (in situ FTIR spectroscopy).
