To the Editor: Regarding the Vatican and the disaffected Anglicans, I have a twofold response: First, is this a precursor to the Vatican's finally accepting a married clergy?
Bergson offers a twofold response.
In a study by [ 66] three different oxidative stressors elicited a twofold response of the rainbow trout MT-B promoter luciferase constructs, comparable to our study with paraquat.
While abatacept reduced the response (geometric mean titers) of the two vaccines, it did not significantly inhibit the ability of healthy subjects to develop at least a twofold response to either the tetanus toxoid or 23-valent pneumococcal vaccine.
Although it lacks an authentic CRE, the 70-bp region also mediated a twofold transcriptional response to forskolin, equivalent to that found with the endogenous gene.
For larger analytes, there is little benefit to using the flow-through scheme for HRP adsorption since less than a twofold improvement in response time was obtained as compared to the flow-over scheme; however, for CAT adsorption, the flow-through membrane provided a much faster response.
Light driven water oxidation was investigated with 5 LbL layer thick polyacrylic acid (PAA)/poly-2 on FTO//(SnO2/TiO2) core/shell electrodes (FTO//(SnO2/TiO2)//(PAA/poly-2 5) which gave a twofold enhanced PAA/poly-2 5 response compared to FTO//(SnO2/TiO2)//(PAA/poly-1)5 (poly-1 containing only Ru-C whichno Ru-Cat moieties present in the polymer).
Among the miRNAs showing less than a twofold change in response to NaCl, the maximum upregulation was observed for sma-miR319a and the maximum downregulation was observed for sma-miR156b (Fig. 2b).
In addition, most of the miRNAs that were present in high abundance with RPM (reads per million) of 50 or more showed less than a twofold change in response to salt treatment.
Criteria used for selection of BAR-1 responsive gene targets were (1) at least a twofold change in signal response to ΔNTBAR-1 overexpression compared with control average, (2) concurrence in directional change for at least two of the three ΔNTBAR-1 induced replicates (e.g., increase or decrease of signal), and (3) an analysis of variance p-value of ≤ 0.05.
Similarly, a halving of the response amplitude in rod ERG b-wave occurred at RGS7 levels of 39±3%3% of available protein, and a twofold decline of scotopic response sensitivity occurred at RGS7 levels of 26±2%26±2%
