Hot flushes are not “in the head,” but new research suggests they may start there. A UA research team has identified a region in the brain that may trigger the uncomfortable surges of heat most women experience in the first few years of menopause.

Hot flushes – also called hot flashes – affect millions of people, and not just women. Yet, it is still unclear what causes the episodes of temperature discomfort, often accompanied by profuse sweating.

Now a team of researchers around Dr. Naomi Rance, a professor in the department of pathology at the UA College of Medicine, has come closer to understanding the mechanism of hot flushes, a necessary step for potential treatment options down the road. This research was published recently in the Proceedings of the National Academy of Sciences. (more…)

Researchers Develop System that Finds Prostate Cancer Metastases Earlier

Researchers at UCLA’s Jonsson Comprehensive Cancer Center have developed a way to image the spread of a dangerous form of prostate cancer earlier than today’s conventional imaging techniques. The new method may allow oncologists to find and treat metastases more quickly and give patients a better chance at survival.

The gene-based imaging system targets castration-resistant prostate cancer, an aggressive form of the disease that has become resistant to the hormone treatment known as androgen-deprivation therapy. Once this treatment no longer works, the cancer will progress within 12 to 18 months, and the prognosis becomes grim, said senior study author Dr. Lily Wu, a professor of molecular and medical pharmacology and a Jonsson Cancer Center researcher.
