[CNR] President Maiani is an exception, as he has been appointed by applying international scientific standards of selection.
Further considerations - Recognising the growing patterns of migration in medical school applicants and the heterogeneity of selection practices internationally perhaps the time has come to draft globally agreed minimum standards of selection practice similar to those for medical education programmes [ 51].
KRAS mutation analysis is now standard for selection of patients for EGFR targeted therapy.
A selection agent that has been used successfully is the antibiotic hygromycin and this has become the standard for selection of soybean SE.
While many assays have been used to assess islet function, we chose the glucose-stimulated insulin secretory profile in a dynamic cell perifusion system as our 'gold standard' for selection of human islets for subsequent study.
While standard tests of selection (i.e. outlier tests) are powerful tools to detect "hard selective sweeps", in which a new advantageous mutation arises and spreads quickly to fixation due to natural selection [ 43], other scenarios might be more difficult to detect.
These files can be used to generate alignments and standard analyses of selection or phylogenetic analyses.
Both scenarios lead to shifts in allele frequencies rather than fixation, thus tend to be more difficult to detect than hard sweeps using standard tests of selection [ 23, 45, 46].
The use of standard tests of selection and a new test that compares patterns of differential survival between synonymous and nonsynonymous in evolutionary time also provide evidence of positive selection across species and of a selective sweep for one of the species investigated.
Furthermore, standard models of selection on codon usage (Li 1987; Bulmer 1991), where the strength of selection scales with N e, cannot explain the results of this study and the general lack of relationship between codon usage for a species and inferred N e for a species.
The availability of hundreds of different adjuvants has prompted a need for identifying rational standards for selection of adjuvant formulations based on safety and sound immunological principles for human vaccines.
