Positive feedback systems are unusual in biology, as they terminate with some cataclysmic, explosive event. A good example of a positive feedback system involves oxytocin and its other effect: causing contraction of uterine muscle during childbirth (Fig. 1.51). In this case the stimulus for ...

Systems Biology Meets Single-Cell Physiology: Role of a Positive-Feedback Signal Transduction Network in Cerebellar Long-Term Synaptic Depression 来自 Springer 喜欢 0 阅读量: 28 作者:K Tanaka,GJ Augustine 摘要: It is widely assumed that persistent changes in the brain, such as those occurring ...
Systemic lupus erythematosus, a prototypical systemic autoimmune disease, is the result of a series of interactions within the immune system that ultimately lead to the loss of self-tolerance to nuclear autoantigens. Here, we present an integrated model that explains how self-tolerance is initially...
The ingredients required for bistability include some sort of feedback — positive feedback (Fig. 1b), double-negative feedback (Fig. 1a), autocatalysis, or the equivalent — but feedback alone does not guarantee that a system will be bistable 3., 4•., 5•., 6•.. A bistable ...
There is a feedback when a system's outputs are looped back as inputs, thus becoming a part of a chain of cause-and-effect circuit. There are two types of feedback loops namely, positive feedback and negative feedback. The feedback loops involve a repeating...
Terrestrial ecosystem respiration increases exponentially with temperature, constituting a positive feedback loop accelerating global warming. However, the response of ecosystem respiration to temperature strongly depends on water availability, yet where and when the water effects are important, is presently ...
Preparation of recombinant baculovirus based on the human sodium iodide symporter which participates radiosensitive positive feedback system Objective To prepare and verify a recombinant baculovirus harboring the human sodium iodide symporter( hNIS) under control of the early growth response-1( ...

feedback information from emotional changes. Thus, an ACCGlu–VTAGABA–VTADA–ACCGlupositive-feedback loop mediates the progression to and maintenance of persistent pain and comorbid anxiodepressive-like behavior. Disruption of this feedback loop relieves hyperalgesia and anxiodepressive-like behavior in...
