In an attempt to revert population trends towards an increasing ?westernization? of dietary habits, the Spanish Atherosclerosis Society (SEA) published in 1994 a document with dietary recommendations for the prevention of atherosclerosis.
In recent years, interest has reverted to population ecology, sometimes in the form of metapopulation models (consisting of a set of populations with migration between them).
This suggests that the rate of initial loss of resistance trait and plateauing from the initial loss of resistance trait are similar in every cycle and unlikely that repeated selection and deselection will revert the population fitness to before initial selection (control).
Notably, when TRAIL treatment was discontinued, the resistant cell population reverted to the initial apoptotic rate.
The effect of treatment in the model was based on SVR rates, such that if patients achieved SVR, they no longer retained the risk of progression to a worse disease stage and reverted to general population mortality rates.
Although reverting admixed populations to exclusively pure genotypes may not be feasible, using spawners with pure native genotypes for stocking programs could further decrease admixture proportions (Hansen et al. 2009).
Interestingly, a significant fraction of these populations reverted to antibiotic sensitivity (Fig. 3A).
On the Arapawa island (New Zealand), the Merino population has reverted to the feral status (Fig. 1d).
Indeed, it has been demonstrated that even a small population of cells derived from a single cancer cell clone (diversified population from a single cell), could be responsible for drug resistance and, upon removal of the drug, the population spontaneously reverted to a sensitive state.
Prolonged culture of pure CD133+/CD133− populations resulted in both populations reverting to a bimodal pattern although in neither case did the pattern revert to that of the original cell line.
