Sentence examples for progressive selection from inspiring English sources

Also, it can happen that the effects of a metabolite selected early on in the progressive selection process, are superseded by one selected later.

PCR-DGGE analysis of DNA obtained from the silt loam soil treated with dibenzothiophene-containing petrol showed the progressive selection of specific fungal bands over time, whereas this selection was not observed in untreated soil microcosms.

With the use of these bacterial strains we provide the first demonstration that, despite a progressive selection for P. aeruginosa with rough LPS during chronic pulmonary infections, loss of the LPS O-antigen does not confer phagocytic resistance in vitro.

While the 1D 13C spectra of fresh plant tissues well differentiated the composition of fresh pine and grass materials, the differences became negligible after decomposition and suggested a similar accumulation of recalcitrant carbon species, thus again supporting a mechanism of progressive selection of hydrophobic degradation products regardless of the plant origin [21].

We previously reported that cART seems to favor the progressive selection of pre-existing minor CXCR4-viruses that were already present in baseline quasispecies [43].

A dynamic progressive selection of the rearranged segment in a heterologous genetic background throughout passages was indeed observed by PAGE, and still occurred – but at later passages – when disadvantageous proportions of r-RV to wt-RV were used for the initial inoculum.

The dynamic conformational changes during Eph ephrin recognition can be described by progressive conformational selection and population shift events, with two dynamic salt bridges between EphB4 and ephrin-B2 contributing to the specific recognition.

In both studies, an analytical evaluation based on a distal pointing model and an empirical evaluation demonstrates that progressive refinement selection can provide significant benefits compared to immediate techniques.

During any immune response, tuning of TCR usage through progressive clonal selection occurs.

The ex vivo fluence rate and PEG-NR photothermal heating measurements, coupled with computational models for two generic device geometries (i.e., silica rod and flexible mesh sheet) allowed for progressive down-selection of candidate devices prior to attempting plasmonic photothermal therapy in an animal model.

As the methylation mechanism is (at least partly) age related, and progressive, a similar selection of tumors methylated on one of the other CIMP markers would have also shown more frequent methylation on these than other CIMP markers including MLH1 and occurring in tumors not reaching the CIMP-high classification yet.
