However, considering that r-RV (M1 to M4) replicated less than or equally to the wt-RV M0, though sharing a same genetic background, it was unlikely that r-RV could have overgrown wt-RV, especially when mixed-infections were performed at MOI ratios favoring wt-RV.
Since most of them had colposcopic diagnosis of HPV/CIN I and had a low socio-economic background, it was unlikely that biopsies with pathological reports in these cases could be met.
Although GBV-B genome-length RNAs and subgenomic replicons were not derived from identical genetic backgrounds, it is unlikely that a ∼7-fold decrease in colony formation activity, as observed here for subgenomic domain III chimeric RNA GBneoD/IIIHC, could account for the lengthy delay in replication of the corresponding genome-length chimeric RNA in vivo in tamarins [3].
In many cases, the region of approximately 1030 to 1070 cm−1 is attributed to fused silica from the instrument optics, but because this study accounted for background signal it is unlikely to be the source of the band.
If the end points of cell proliferation, differentiation, or cell death are not seen at frequencies above background levels in an organism, it is unlikely that low-level radiation would play a role in the multistep processes of chronic diseases such as cancer.
However, it is unlikely that background purifying selection started to act on a large non-coding region only at a certain point during the last 20 25 MY, after the divergence of humans and rhesus lineages.
It is unlikely that background exposure will have effects if the blood lead concentrations in the TLC trial did not.
Given that concentration data for periods of the year when atrazine concentrations increase over background were collected every 7 14 days, it is unlikely that interpolation of these data resulted in significant bias.
It is unlikely, however, that the background will contribute significantly to the total post-Fukushima contamination of foods.
Thus, it is unlikely that the reduction in CRC mortality could be due to background differences in overall mortality.
