When the simulated databases were not contaminated (level of contamination = 0%), the SEs of the two models were identical at the 2nd decimal point (Table 2).
As expected, both models accurately estimated β1 or log (RR) when the simulated databases were not contaminated (level of contamination = 0%).
When the data were contaminated (level of contamination > 0%), the relative biases were all negative, indicating that the point estimates were biased towards null.
Therefore, contaminating levels of native perlecan within the enriched recombinant preparations would have also been detected with the A76 antibody, but were not.
The impact therefore of contaminating levels of eukaryotic RNA after amplification (using either method) and hybridisation to a M. tuberculosis microarray was minimal.
Octabromodiphenyl ether has been shown to cause fetal effects at maternally toxic doses, and contaminating levels of 2,2′,4,4′,5,5′-hexabromodiphenyl ether has also been reported to induce developmental neurotoxicity and perturb several hormonal pathways.
A majority of the supply wells in the HP system were not contaminated, so contamination levels varied depending on the wells in use at a particular time [ 1].
However, doubts have been raised as to whether the purported cellular levels of CECs might be contaminated with levels of other haematogenous cells, in particular large platelets (Strijbos et al, 2007, 2008; Starlinger et al, 2011).
Some 15 percent of coriander and 12 percent of oregano and basil shipments were contaminated, with high contamination levels also found in sesame seeds, curry powder and cumin.
