There is a subset of CV in which serum cryoglobulins may appear to be negative by initial laboratory testing for various reasons, such as low cryoglobulin levels, problems in blood sample handling or testing, or owing to tissue deposition rather than blood circulation of immune complexes.
When consumers read the review to find out why the product received a specific rating, what may appear to be a negative review can prompt a purchase.
These results are consistent with the idea that the most cancerous specimens may appear to be MUC1-negative if probed with antibodies against the full-length protein alone.
The clinical examination result is initially negative and may appear only when the duodenal contents enter the peritoneal cavity.
Though doubtful or even negative results may appear sometimes (for instance, Pinheiro et al. 2010; Verlinden et al. 2010), recent reviews state their general usefulness for crops under field conditions (Rose et al. 2014).
As a result, false negative results may appear.
Such differences are sufficient to change data interpretation: experiments that should yield a negative result may appear positive, or vice versa.
Vitrification is the state-of-the-art specimen preparation technique for molecular electron microscopy (EM) and therefore negative staining may appear to be an outdated approach.
In association, negative symptoms may appear quite stable in the lower range hence not allowing a clear distinction between categories of subjects for this parameter (our data show almost same results for all groups, with a quite small DS).
Besides, even though all the sites in a protein are under negative selection, various negative selection pressures still may appear in different domains in a protein.
