A 15 year old competitive female basketball player presented to a chiropractor subsequent to an unsuccessful course of conservative treatment for posterior tibial dysfunction.

Steroid hormones acutely regulate expression of a Nudix protein-encoding gene in the endometrial epithelium of sheep.

Steroid hormones regulate endometrial gene expression to meet the needs of developing embryos. Our hypothesis is that steroid hormones transiently induce expression of genes in the endometrial epithelium to make the uterine environment different between the earliest days of pregnancy. We identified one such gene product using differential display-polymerase chain reactions.
