It is proposed that the activity of this high affinity phosphate transport system may be especially pronounced in the later stages of the aerobic phase when P concentrations are limited (Fig. 4b), and that a low affinity inorganic phosphate transporter (Pit) is the more active system during the other stages [4].
While Helitrons were active during the early stages of vesper bat diversification, other DNA transposon families have since invaded and been active in these genomes.
One group ate during its active hours, the other only during its normal sleeping period, but both groups consumed about the same number of calories.
In a double-dummy design the patient receives active treatment X and placebo treatment Y during one period, and placebo treatment X and active treatment Y during the other.
Our data show that inactive p63-bound enhancers in epidermal keratinocytes may be active during the development of other epithelial-related structures such as limbs and suggest that p63 bookmarks genomic loci during the commitment of the epithelial lineage and regulates genes through temporal- and spatial-specific active enhancers.
If some of your fish are active during the day and others at night, feeding them at two different times may help ensure that each fish gets enough food.
Sleek and lithe, cobras are active during the day, often hunting other snakes.
"What we think this might mean is that these de novo, new, genetic changes may be more relevant to early onset cancers with an impact on fertility," says Stadler, since testicular cancers more often occur during reproductively active years than the other cancer types.
Each patient received during one period of each pair the active treatment (treatment X), and during the other period the control treatment or placebo (treatment Y).
While five of 11 participants with virological failure received ART regimens that were not or only partially active, the other four became resistant during the therapy in spite of a fully active ART regimens initiated at baseline (Additional file 1: Table S1).
