These effector caspases initiate feedback amplification loops and are the ultimate executioners of apoptotic cell death.
They also realised that they could use the team working methods employed by physiotherapists; for example by initiating feedback and cross-referral by email to other members of the chronic care team.
The future expansion of tundra shrubs [10], [16] coupled with decreased effective moisture [8] could thus enhance circumpolar Arctic burning and initiate feedbacks that are potentially important to the climate system.
After the hand movement is initiated, the feedback motor command is generated using the sensory (e.g., visual) feedback signal associated with the ongoing movement in order to adjust the movement in mid-flight (feedback control) [9], [10], [13].
TGF-β1 further initiated a feedback loop stimulating endothelial Semaphorin3A expression, thereby amplifying the stabilizing signals.
Down-regulation of HNF1α initiates a feedback circuit consisting of HNF1α, SHP-1, STAT3, p65, miR-21 and miR-146a, and this feedback loop perpetuates hepatic fibrogenesis.
The loss of sea ice initiates a feedback loop known as Arctic amplification.
Because Mpk1K54R contains a Lys to Arg point mutation in its kinase domain that abrogates its kinase activity [31], this mutant is able to receive Mkk1/Mkk2 directed phosphorylation at Thr190/Tyr192 but is unable to become activated, thus incapable of initiating the feedback.
The wheel stopped on one of the ten segments, initiating the feedback period.
The higher levels of adiposity in turn lead to greater insulin resistance, thereby initiating a feedback cycle of increasing cardiometabolic risks mediated through insulin (2, 34, 35).
It is likely that DS, by activating kinases upstream of ERK1/2, initiates a feedback loop that suppresses IL-1β-induced ERK1/2 activation.
