Universals, if they indeed exist, are, in the first instance, properties or qualities or attributes (i.e., "ductility" or "whiteness") that are supposedly universally "present in" the members of classes of things and relations (i.e., "being to the north of") that are supposedly universally present in the members of classes of sequences of things.
Because inflammation and endothelial activation are reportedly universally present in the acutely ill [[2],[19]], we tried to expand the patient groups in which changes in MPV may be relevant to prognosis by studying a broader range of critically ill patients.
As Nippert-Eng writes, "This is the one category of objects that is overwhelmingly absent for participants who carry only wallets, yet universally present for those who carry purses" (here: 130).
We have not found genomic alterations universally present in all (100%) three subgroups of NBs.
But they are not limited in their occurrence to haloarchaea, nor are they universally present among the latter.
This study reveals that the quorum sensing system that utilizes the AHL class of signals is not universally present in the genus Novosphingobium.
The S. aureus- and S. epidermidis-specific core genomes, those genes universally present in one species and universally absent in the other, was 374 for S. epidermidis and 400 for S. aureus isolates in this study.
Here, we extend this method to the whole genome by identifying a core set of 1,478 genes universally present within the 181 S. aureus isolates and 143 S. epidermidis isolates in this study.
Besides the essential RNase III and dsRNA-binding domains (Table 3), the other 50 additional domains were not universally present in the Dicers in plants, animals, and fungi (Additional file 4).
We have not found genomic alterations universally present in all (100%) three subgroups of NBs, although such a region would be interesting since it may harbor specific genes that are uniquely responsible for NB tumorigenesis.
