Different findings among studies may be also explained by differences in concentration and duration of HBCD exposure; further studies are required to define the effects of HBCD, particularly in female mice.
This is likely caused by differences in concentration and purity, as the DNA of the standard strain was isolated directly from pure bacterial culture, and the clinical samples contained a lower bacterial load and the isolated DNA was not as pure as that of the standard strain.
The difference in translation speed between the four UCN codons and the two AGC/AGU codons under biofilm-inducing conditions is likely mediated by differences in concentration of the corresponding aminoacylated tRNAs (Elf et al., 2003; Dittmar et al., 2005), as was recently observed in serine-starved E. coli (Subramaniam et al., 2013).
This could mean that the siRNA concentrations employed to derive most of the entries in SIR are similar to those in the other datasets, or that the feature selection process is not significantly affected by difference in concentrations amongst datasets, or both.
Activation of specific host defense pathways appears to differ between the two infections, as indicated by differences in circulating concentrations of key regulatory proteins.
However, bone loss begins around age 30 in men and women and this early bone loss cannot be entirely explained by differences in E2 concentrations or by our proposed model [ 78].
When plotting these as a function of local actin concentration, we found a robust negative linear correlation, which shows that flows are driven by differences in actomyosin concentration, validating quantitatively Equation 3 of our model.
A heartbeat is produced by electrical current generated by differences in the concentration of various ions.
As shown in Table 4, the variation in top-5 AGI change is almost completely explained by differences in income concentration and capital gains receipt.
Driven largely by differences in N concentration, aspen litter exhibited markedly lower C∶N than either coniferous species, while litter C∶N did not differ significantly between pine and spruce (Table 2).
