Figure 3From: Episodic, transient systemic acidosis delays evolution of the malignant phenotype: Possible mechanism for cancer prevention by increased physical activityEffect of transient acidosis. (a) Variation in the development rate R with proportion of time under exercise. Exercise is assumed to correspond to high acidity (h X = 400), whilst during rest acidity drops to normal levels (h X = 0). (b) Variation in epithelium survival with exercise time.Back to article page
