feedbacks acting in tandem. With increased water vapor, for example, there may be greater short wave reflection which acts as a stabilizing feedback effect. The relative strength of the water vapor feedback effects is said to be a key factor influencing climate sensitivity (IPCC, 2007, p. 9...
A negative feedback loop is a reaction thatcauses a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or...

These previous data brought us an idea that the establishment of nucleus-mitochondria positive feedback loop induced by chemo-radiation may play a key role for inducing persistent and irreversible SASP. To the best of our knowledge, we could not find any paper even review, except for ours, ...
For example, positive feedback is known to amplify a response and commits into a self-sustained mode that is autonomous to the original stimuli. It is tempting to speculate that, once induced by TGF-b, the miR-1269a-mediated feedback loop allows CRC cells to become more autonomous. This ...
The two element mutual activation and inhibitory positive feedback loops are a common motifs that occur in many biological systems in both isolated and interlocked form, as for example, in the cell division cycle and thymus differentiation in eukaryotes. The properties of three element interlocked po...

Mitochondrial morphology is remodeled by continuous dynamic cycles of fission and fusion. Emerging data have shown that the disturbance of balance between mitochondrial fission and fusion is involved in the progression of several types of neoplasms. Howe
