An examination of the ratios of the 16 repetitively spotted flavonoid 3' hydroxylase cDNAs using a t test showed that the mean ratio of the repeated cDNAs on replicate 1 (2.424) were statistically significant at a P value of 0.0001 when compared to an expected mean of a 2.0, or a two-fold expression difference.
The research used an examination of the ratios between different isotopes of carbon in methane, and at least tentatively attributed increasing global emissions to agriculture.
In effect, the criteria used in the QIPP score reflect the extent of purifying selection acting upon a sequence, which, in the absence of homology, preclude the use of more widely-used methods such as examination of dN/dS ratios [38].
More recent studies emphasize that examination of log ratios rather than expression intensities will greatly increase the observed correlation coefficients [ Park et al., 2004].
Examination of cortols/cortolones ratios as an additional measure of 11β-HSD1 activity supported these findings, being significantly greater in the early persistent arthritis and early persistent RA groups compared to patients whose synovitis subsequently resolved.
In general, examination of allelic ratios of RAS-pathway alterations in comparison to cellularity estimates suggested that RAS-pathway mutations may be more likely to be hemizygous or homozygous (Additional file 1) although copy number analysis was not available to validate this.
Examination of the ratio of the observed occurrences to those expected from the mononucleotide composition (obs/exp) showed that directional changes of many 5-mers cannot be explained by a cumulative effect of mononucleotide changes (data not shown), as found for various dinucleotides.
Examination of t-ratio associated with the coefficients of variables in the MLE version of the conditional revenue frontiers shows that it is only the influence of five variables - LNPOIL, LNCLAND, LNANU, LNHRLAB and LNADLAB that were significant.
However, a critical examination of sex ratio produced in response to temperature in fish has never been carried out.
Examination of the ratio of transitions (ts) to transversions (tv) causing these private substitutions in mtAncestor-1 and mtAncestor-2 is the next test allowing us to confirm that the pattern of nucleotide substitutions arose in the mitochondrial genome.
Examination of the ratio of wild-type expression to mutant expression revealed that the siPrnp102(T9)-12C, -13A, -14U and -17G duplexes (Figure 2B) and the siPrnp105(T10 -14U T10 -14U duplexes (Figure 2F) andear to have markedly improved ASP-RNAi activity.
