In the work of Zeng et al. [34], electrical conductivity is analyzed as a function of the oxygen defect and they obtain a decrease of the activation energy as soon as the defect of oxygen is higher.
As shown in figure 4, our data revealed that ischemia induces a robust microglia/macrophages activation observable as soon as 4 h, the earliest time point investigated in our study.
Although HSCs have strongly reduced expression levels of activation genes as soon as 2 days after incubation with RM, intra-cytoplasmic lipid droplet accumulation is only observable after 4 days (Additional file 1: Figure S2).
S-phase synchronised cells showed activation of Chk1 as soon as they were released from the block, while phosphorylation of Chk2 was observed from 20 minutes.
To test the hypothesis that the flooding-dependent activation signal is perceived as soon as after 24 h of flooding, we flooded plants for 24 and 48 h, and observed the subsequent adventitious root emergence, in humid air (Fig. 6).
Activation of PKCs was detected as soon as 1 h following acadesine addition, a time point that precedes the onset of autophagy.
As soon as activation in a perception-action circuit overcomes the "ignition threshold", it then grows very rapidly, almost "explosively" (time-steps 3 5), outperforming (and suppressing) all its competitor circuits; this can be seen as reflecting a choice, or decision, being made between potential alternatives.
This is due to the presence of the FI mechanism: the area-specific inhibition loop takes effect as soon as the activation within one area increases and remains active for a few steps; this prevents activation from immediately 're-entering' an area which has just been active.
In this substrate, the sequence VDVAD could be specifically recognized and cleaved by caspase-2 as soon as its activation was initiated with treatment of a certain dose of cisplatin to HeLa cells, which led to a break of the substrate into two fragments.
Though the Master Chief and Arbiter form a tenuous alliance with the Flood to stop the activation of all the Halo rings, as soon as the firing sequence is stopped Gravemind turns on them.
