Furthermore, given the reciprocal effects of pharmacological CFTR inhibition (pro-inflammatory) and activation (anti-inflammatory) giving rise to a near 50% difference in levels of a critical hub in inflammation, we concur with Vij et al that that the inflammation suppressive action of wt-CFTR might require an active channel.
An alternative hypothesis is that stemness might require an active process at the interface to the RPE; it is also possible that both scenarios are involved.
For example, one might require an active compound to have a potency of at least 100 nM to qualify for the formation of an activity cliff with an inactive one.
Furthermore, the need to use a laser and microwaves leads to warming of the sample, which might be problematic for some applications and thus require active cooling or temperature stabilization.
However, the increasing wind power integration may require active participation from WPPs in secondary frequency control in future power systems along with conventional power plants, as some conventional power plants might be replaced by WPPs.
Becoming decisive will require active, conscious effort.
The analysis confirms that climate change might require the installation of active cooling systems to compensate for harsher summer conditions over a long-term horizon, however, in the mid-term, passive cooling strategies combined with envelope refurbishment may still guarantee thermally comfortable conditions, and they will reduce energy cooling needs when active cooling is eventually installed.
If the oxidative products generated by radiation are the actual carcinogenic agents, and if these are predominantly destroyed by metabolism-dependent processes that operate at rates that scale with metabolic rates, it is possible that achieving comparable integrated dose × time levels of the active agents might require the same (body weight)0.75 conversions as used for chemicals.
This results in a continuous withdrawal of guanine precursors, such as guanosine and its nucleosides and nucleotides, so that, dGTP, required for mitochondrial DNA replication, might become limiting, therefore requiring active import of either its precursors or dGTP itself.
To detect this "hidden" activity for the five non-active strains, the strains might require optimization of culture conditions or certain biological cues from the environment.
