The major limitation of airbrush matrix application is that the velocity of the spray is controlled manually and cannot be strictly monitored.
For example, samples are from cultures growing on hexose (transcriptome) or pentose (proteome), and cannot be strictly compared due to undetermined effects on the regulatory milieu, gene expression, relative abundance of transporters and branching central metabolic pathways more generally [ 12].
"Dramas as singular in theme and temper cannot be strictly called comedies or tragedies", he wrote.
While PS1 appears to be a much more successful parameter set, PS2 and PS3 cannot be strictly excluded.
Finally, it must be emphasized that phenotypic change in the wild, as reported in empirical studies, can be caused by a range of factors other than evolution and therefore cannot be strictly compared with evolutionary rates reported in modelling or experimental studies.
In this review the authors discuss the involvement of specific macrophage subpopulations in these processes and the complexity of defining macrophage subpopulations in vivo, since the in vitro criteria used to define M1 and M2 macrophages cannot be strictly applied to in vivo settings.

Although the studies of Johansson et al. (2010) and Zhang et al. (2012) cannot be strictly compared with ours because of differences in the number of selection generations (50 and 11 vs. 7), marker density (60 k vs. 9.4 M SNPs), and methods used to detect selective sweeps (line-specific alleles and EHH vs. hapFLK), the number of sweeps was quite similar (163, 108, and 129, respectively).
Although isolation of patients with positive sputum smear microscopy results should be attempted, in daily practice, strict isolation of a patient is often not possible and infection control measures by hospital staff often cannot be strictly enforced.
