But the persistence of such new bone is questionable and its differentiation from the bone which grows from the connective tissue cells is often impossible.
However, a series of oncocytomas has recently been reported in which a Vimentin positivity has been observed, making the differentiation questionable, particularly in preoperative evaluation [ 8].
Question questionable sources.
PCA analysis of the UV spectra revealed that this approach was able to distinguish pure heparin from the spiked heparin preparations (Figure S3A and B), yet this differentiation was questionable for contaminant levels lower than 1%, since spectral fluctuation could mask the results.
In addition, whether ES cell lines are an appropriate model to study in vitro trophoectoderm differentiation is questionable based on the observations from the recent publication discussed above: the initiation of imprinted XCI was not possible in vitro, but required in vivo differentiation (Murakami et al. 2011).
However, as there were only two biological replicates used by Glover et al. [ 19] for each differentiation protocol these results may be questionable.
In questionable cases MRI with DWI can usually make this differentiation.
However, the differentiation of internal and external attribution is somewhat questionable.
Coming on the heels of the 2008 financial crisis and the ensuing Occupy movement, Piketty's book has been held up as an incontrovertible truth, without differentiation between his remarkable historical work and his more questionable interpretations and policy recommendations.
Nevertheless, cloning and sequencing helped us to verify questionable or unclear SNaPshot™ results by permitting the identification and differentiation of cryptic contaminations, PCR artefacts and SNaPshot™ reaction failures.
Consequently, the differentiation of the tolerance based on the relative ion intensity is questionable, and one may end up in rather arbitrary situations with respect to identification.
