In contrast, the lower the incidence of intervention, such as is found in those countries with high rate of home births Archived 2020-11-11 at the Wayback Machine, and birth centers worldwide, the higher the likelihood of the Ferguson Reflex occurring. This may explain the lack of research, considering the public health benefits of such ...
Prolactin and oxytocin trigger the release (letdown) of milk and its ejection from the nipple in a positive feedback loop. [4] It was previously thought that prolactin hormone, which is released by the anterior pituitary in response to the direct nerve stimulation of suckling, was responsible for creating the hormonal pathways necessary to ...
Positive feedback (exacerbating feedback, self-reinforcing feedback) is a process that occurs in a feedback loop which exacerbates the effects of a small disturbance. That is, the effects of a perturbation on a system include an increase in the magnitude of the perturbation. [ 1 ]
A positive feedback loop speeds up a process. Meadows indicates that in most cases, it is preferable to slow down a positive loop, rather than speeding up a negative one. The eutrophication of a lake is a typical feedback loop that goes wild. In a eutrophic lake (which means well-nourished), much life, including fish, can be supported.
Production and secretion of oxytocin is controlled by a positive feedback mechanism, where its initial release, either naturally or in pharmaceutical form, stimulates production and release of further oxytocin. For example, when oxytocin is released during a contraction of the uterus at the start of childbirth, this stimulates production and ...
Anabely Lopes wanted a child more than anything, so the 44-year-old was ecstatic when she became pregnant last year — and then devastated when doctors said her unborn child had a fatal abnormality.
After the child sex abuse scandal involving Penn State football coach Jerry Sandusky, Florida legislators in 2012 passed a law that placed a greater responsibility on ordinary people to report ...

[147] Premature birth is the leading cause of death in children under five years of age though many that survive experience disabilities including learning defects and visual and hearing ...
