Prophylactic bilateral Salpingo-oophorectomy and eventual development of endometrial cancer: Two individual case reports.

Prophylactic bilateral salpingo-oophorectomy (PBSO) is regularly performed when patients have a high risk of developing ovarian cancer (i.e. a personal or family history).

Effects of U50,488, a selective kappa agonist, on atypical mouse opiate systems.

We have proposed that endogenous opioids play a critical role in the etiology of anorexia nervosa, mediating an auto-addiction, and that atypical opioid systems in mice may be representative of those in anorexia nervosa patients, in contrast to normal humans and rats. A biological predisposition to eating disorders may result from these atypical opioid systems. Definition of these systems as atypical is based on their responses to morphine, which are preferential for the mu receptor subtype.

Atypical endogenous opioid systems in mice in relation to an auto-addiction opioid model of anorexia nervosa.

We have proposed that the atypical opioid system in the mouse may be representative of that in the anorexia nervosa patient and may account for a biological predisposition to the disorder. This is in the context of our auto-addiction model of anorexia nervosa in which endogenous opioids play a critical role in its etiology. Morphine activation of the endogenous opioid systems increases food intake and causes sedation in most species, including normal humans and rats.
