Due to known non-porous structure of ZnO, the pores observed were due to inter- and intra-particles agglomeration of secondary and tertiary types.
Therefore, the phenotypes observed were due to the deletion of the genes encoding XlnR and ClrB showing the importance of both TFs in the degradation of wheat straw in A. niger.
Moreover, an exhaustive examination of the data was carried out to reject sample plots on which illegal logging had been detected to make sure that the reduction in number of trees observed were due to natural mortality.
The diurnal variations observed were due to the tidal variations in the MLT region (Brenton and Silverman, 1970; Fukuyama, 1976; Shepherd et al., 1995, 1998; Liu et al., 2008a).
Ferguson and Woodbury (2006) studied the use of groundwater for cooling purposes in four buildings in Canada and found that the increases in temperature observed were due to the spacing between injection wells being smaller than the optimal spacing for such systems.
The very low activities observed were due in part to high accumulation rates and the dilution effect of the radioisotope in the large mass of sediment, and in part to generally low 137Cs fallout at this latitude (see discussion in Szczuciński et al., 2009).
To ensure that the effects observed were due to inhibition of ETS proteins, we reduced ERG protein expression in VCaP cells using siRNA.
Our analysis of the microarray data assumed that any differences observed were due to the fibrocytes and not contaminating monocyte, or monocyte-derived populations.
The main limitation of the study was the absence of a control group to ascertain that the findings observed were due to the intervention and not unrelated factors.
Because each group had an equal probability of containing hosts with aberrant behaviour, this minimized the possibility that any behavioural changes observed were due to parasitoids selecting hosts with atypical behaviour, rather than a consequence of parasitism [4].
This is consistent with results of similar experiments performed with Rab11 hypomorphs, where eye morphology defects observed were due mainly to late events: cell death and the failure to form light-gathering rhabdomeres [45], [53].
