Gastric bypass does not influence olfactory function in obese patients.

Morbidly obese individuals have altered sense of taste and smell. Gastric bypass (GBP) alters taste but olfactory function has not been evaluated. Changes in these senses may influence dietary preferences following GBP.

Genetic determination of susceptibility to estrogen-induced mammary cancer in the ACI rat: mapping of Emca1 and Emca2 to chromosomes 5 and 18.

Hormonal, genetic, and environmental factors play major roles in the complex etiology of breast cancer. When treated continuously with 17beta-estradiol (E2), the ACI rat exhibits a genetically conferred propensity to develop mammary cancer. The susceptibility of the ACI rat to E2-induced mammary cancer appears to segregate as an incompletely dominant trait in crosses to the resistant Copenhagen (COP) strain.
