The phrase "activated by low" is not correct and lacks clarity in written English.
It may be intended to describe a condition or state triggered by something low, but it needs additional context to be meaningful.
Example: "The device is activated by low voltage levels to ensure safety."
Alternatives: "triggered by low" or "initiated by low".
We first established that the Phox2b on /Atoh1 on subset of RTN neurons are (i) rhythmically active, (ii) are activated by low pH, and (iii) both necessary and sufficient for optogenetic entrainment of the phrenic nerve.
The endosome acidification inhibitors are thought to enhance the CD4-independent HIV-1 vector infection by suppressing cathepsin B activity, because cathepsin B is activated by low pH in acidic endosomes.
Secondly, the proteasome structure might be modified by oleic acid as proteasomes are activated by low concentrations of surface-active molecules including detergents.
Specifically, the high Ca2+ affinity of SK2 channels suggests they may be activated by low or moderate efferent activity, whereas BK channels, with lower Ca2+ affinity, would be preferentially activated by stronger efferent activity (as suggested by our experiments with long puff applications of ACh).
Interestingly, calcineurin, the activity of which depends on Ca2+/calmodulin binding, can be activated by low concentrations of free lead while higher concentrations reduce its activity [ 35].
The activity of MCT in RBC is also activated by low pH [ 68].
Both devices used a 25 μm thin PVDF film whose surface was activated by low-energy argon plasma.
Two types of GABAergic inhibition have been described: αβγ receptors mediate phasic inhibition in response to transient high-concentrations of synaptic GABA release, and αβδ receptors produce tonic inhibitory currents activated by low-concentration extrasynaptic GABA.
These results suggest that many signaling proteins, including Erk, Akt, Shc1, CrkL, Cbl and Gab1, can be activated by high-affinity receptors, whereas others, including PLCγ1 and the Stat proteins, are only activated by low-affinity receptors.
The fact that Stat3 is only activated by low-affinity receptors in every cell type that we examined suggests that in vivo concentrations of EGFR ligands can stimulate low-affinity receptors and identifies a possible role for low-affinity receptors in the in vivo signaling of cancer cells.
In prostate cancer, photosensitizing drugs are given orally or intravenously and later activated by low-energy light transmitted within optical fibers placed directly within the prostate with TRUS and perineal template guidance.
