The sensitivities of these techniques have also been questioned, particularly in reference to more recent methodologies, such as polymerase chain reaction (PCR).
29 More recent methodologies include Pd-catalyzed three-component methods, 30– 33 addition of alkylchloroaluminum amides to nitriles, 34 aryne insertion into thioureas 35 and ytterbium-catalyzed addition of amines to nitriles.
Although initial studies (for review see [ 14]) were implemented using rather crude stimulating devices, some of the more recent methodologies allowed quantitative evaluation of this sensory modality [ 14, 15, 20, 21].
Hence, although the FDA guidance infers that PRO instruments should aim to measure the adverse consequences of treatment separately from the effectiveness of treatment, more recent methodologies would support efficacy (or effectiveness) data being collected from the same dataset as safety, and may in fact improve the utility of the information [ 33].
A more recent overview of methodology used to analyze GC content variation within genomes can be found in Bernaola-Galvan et. al., [ 30], and a study of how intra-genomic GC content variation affects codon usage is described by Daubin et. al. [ 31].
Using similar methodology, a more recent study made similar extrapolations from data collected in Utah and Colorado, arriving at a total population figure slightly less than one million [ 5].
However, a more recent meta-analysis based on the Cochrane methodology, including 12 randomized controlled trials of 6 14 months' duration, reported that the beneficial effects of treatment were slight and that only TC was affected [ 54].
In a more recent paper, Beaton (2010) applies a time-varying parameter methodology for USA and Canada and finds evidence of asymmetric behaviour in Okun's law over the business cycle.
These results are similar to Nutt's original work and to a more recent Dutch study, 5 which used the same scoring system but different methodology to this study.
We then investigated a more recent ordering of sequence contigs on the barley genome provided by the POPSEQ methodology [ 29].
