that, interestingly, the basic receptor function of hOR17-4 seems to be identical in both human sperm and olfactory neurons. In light of their findings, the authors propose a model in which a single receptor protein helps perform diverse chemosensory...

Does a time delay between prostate cancer diagnosis and start of radiation treatment matter?

that a delay, within the limits of this study, from the time of diagnosis to the start of treatment with external-beam radiation does not alter ultimate clinical outcome," Andrews stated. "Another important finding here is that the use of hormone th...
