It can be used to describe a process or action that is initiated or triggered by a specific group or individuals.
Example: "The alarm system is activated by them whenever they enter the building."
Alternatives: "triggered by them" or "initiated by them".
Let us imagine the existence of what we might name "timer units" (receptor subunits, proteins, channels…) that would provide receptors (or molecular structures that are activated by them) with distinct temporal activation profiles.
"It just tells us that even though these are weak signals, the human brain is activated by them".
The reality is that often change is being done to them, rather than activated by them – and scant effort has been made to demonstrate how the latest proposed changes to the health service are any different.
There is an intricate interplay between adhesion complexes and Rac1, since Rac1 can trigger their assembly, but can also be activated by them.
Hence, the ultimate result following an oxidative insult, that is, survival or cell death, may depend upon the prevailing stress levels and the subsequent signaling arrays activated by them.
For phospholipid measurements gametocytes were activated by transferring them to gametocyte activation medium (GAM), RPMI 1640 with 20 mM Hepes, 4 mM sodium bicarbonate, pH 8.0 containing 100 µM XA, unless otherwise stated.
Membrane surfaces were first cleaned and activated by exposing them to O2 plasmas.
Some of the latest coupons from retailers and other businesses can only be activated by sharing them with Facebook friends or Twitter followers.
Silicon wafers with thin oxide layers were activated by immersing them for 30 min in piranha solution (H2O2/H2SO4 = 1/3) and they were vigorously rinsed afterward with deionized water for 30 s or 2 min, immersed in Millipore water and ethanol, followed by dichloromethane.
On the other hand, compared to control SAG1-HA gametes undergoing receptor-activated signaling induced by mixing them with hap2 minus gametes, SAG1-HA gametes that had been activated by pre-incubating them with db-cAMP and then mixed with hap2 gametes, released increased amounts of SAG1-C65-HA inthethe medium, even when staurosporine was also added to the medium.
Later, following a single-cell analysis approach, that analyzed the expression of a Pspo IIA -gfp fusion activated by Spo0A, allowed them to conclude that the autostimulatory activation of Spo0A is responsible for the bistable expression pattern in sporulating cultures [ 112].
