For example, organisms breathe subconsciously, and can avoid pain through the nervous system, even small beings without the capability of thinking can perform their biological processes. Feedback systems have f
positive feedback systemdynamical propertiescancer cells resistanceWe are concerned with dynamical properties of models of emergence of resistance of cancer cells to chemotherapy, based on recent progress in molecular biology. The model of the process has a form of the infinite system of linear and ...
Negative feedback in a system occurs when the system functions in such a way that the effects of a disturbance are counteracted over time, bringing the system back to its predisturbance state. In landscapes, an example of negative feedback occurs when deposition of coarse sediment takes place ...

Example: “Thanks for being someone I can always rely on, John. We’ve been helping each other out since we started training together, and it’s made such a huge difference during my time here.” Giving positive feedback to your direct reports and company leaders is important, but don’...
What is feedback? What is a feedback loop? Distinguish between a positive feedback loop and a negative (corrective) feedback loop in a system, and give an example of each. What is the best way to describe a positive and negative feedback loop in biology? What is an example of positive...
Bistability is ubiquitous in biological systems. For example, bistability is found in many reaction networks that involve the control and execution of important biological functions, such as signaling processes. Positive feedback loops, composed of speci
Long noncoding RNAs (lncRNAs) have been reported to exert important roles in tumors, including clear cell renal cell carcinoma (ccRCC). PVT1 is an important oncogenic lncRNA which has critical effects on onset and development of various cancers, however,

Cells respond to cytotoxic DNA double-strand breaks by recruiting repair proteins to the damaged site. Phosphorylation of the histone variant H2AX at S139 and Y142 modulate its interaction with downstream DNA repair proteins and their recruitment to DNA
