Multiple tumor-secreted factors act on the bone microenvironment to drive a feed-forward cycle of tumor growth.
Following transmigration into the intima, these cells mature into inflammatory macrophages, and their secretion of pro-inflammatory cytokines further promotes endothelial activation, and serves to drive a feed-forward loop that perpetuates leukocyte recruitment (Pober & Sessa, 2007).
The extreme abundance of seeds might be able to drive a consumer to shift towards feeding on the producer trophic level at such a degree that would not otherwise be found under normal circumstances owing to the lower nutritional quality of plant foods.
In these neurons, Ca2+entry through plasma membrane Cav1 channels drives a sustained feed-forward stimulation of mitochondrial oxidative phosphorylation.
"I consider the controllers, that I use to drive and feed the motors with noise, as a part of the machine and not as something external," Baecker explains.
Rather, the VTA-NAc axis may well drive feeding behavior induced by cannabinoids in both Ay and WT mice.
Driven by feeding efficiency, the populations associated with this new host have differentiated into a new bug ecomorph characterized by short beaks more appropriate for feeding on the flattened pods of the Chinese flametree.
Local had been driven by a feed of national programming from the network.
Greece's short-lived 'PV Spring off 2009-2013, driven by a feed-in tariff scheme, provided a glimpse of the country's real solar potential.
These results are consistent with the notion that place cells form preconfigured assemblies or 'charts' (McNaughton et al., 1996)—an active but unassigned chart being associated with the cued arm during GOAL-CUE, but do not preclude the possibility that place cell firing is driven in a feed-forward manner (e.g., Hartley et al., 2000).
