The possibility of division of labor and evolution of specialist enzymes has also been demonstrated in theoretical studies of surface metabolism [ 13] and compartmentalized systems [ 14], however only for a few enzyme specificities and without modeling of enzyme-substrate interactions.
Candidates were then proposed according to their ability to regulate many targets (coverage score) or to be specific to a set of few targets (specificity score), so that an output of 50 to 100 molecules could be further considered to easily screen the upstream key regulators.
However, in a few cases, specificity was reduced in the dimer probes.
Besides these lesions, in which Gd-EOB-DTPA has a clear advantage, there are a few where the specificities of this agent can be troublesome: haemangiomas, focal fat/sparing, foreign body reaction, cholangiocarcinoma and metastases.
Notably, autovaccination induced only few novel antibody specificities.
Few meta-QTL specificities were observed among mapping populations, suggesting that sources of resistance are not independent.
In contrast to previous similar meta-QTL studies of quantitative resistance [ 25, 26], few meta-QTL specificities were observed associated with the parental source of resistance.
Interestingly, A*24, a suggested risk factor in our work, is one of the few HLA-A specificities with the Bw4 epitope.
An exquisitely wrought, ineffably tender study of a pension-age marriage in silently dignified crisis, it even has Fifty Shades trumped for the fest's most memorable sex scene: Charlotte Rampling and Tom Courtenay enact the pained pauses and pressures of older intercourse with a specificity few actors, and fewer films, dare.
Although encouraging advances have been achieved in the last few years, the specificity and oral bioavailability of the new chemotherapeutic agents seem to pose a challenge to medicinal chemists.
