Hormone receptors now occupy a central role in our current ideas of signalling mechanisms. The fact that about four,000 publications in the year 2004 have been about nuclear hormone receptors alone illustrates this point nicely (B. O’Malley, personal communication).

In Western ladies older than age 50 yr, the speed was 27 per 100,000 per 12 months (1.35 per 1000 per 5 yr), as noticed, for example, in the WHI RCT of combined E+P therapy.
