Investigators identify, assess underlying mechanisms that may explain diet’s 25% reduction in cardiovascular risk for American women. A new study by investigators from Brigham and Women’s Hospital, Harvard Medical School, and the Harvard T.H. Chan School of Public Health offers insights from a cohort study of women in the U.S. who reported consuming a Mediterranean-type diet. Researchers found a 25 percent reduction in the risk of cardiovascular disease among study participants who consumed a diet rich in plants and olive oil and low in meats and sweets...

Men with inflammatory bowel disease have 4 to 5 times higher risk of being diagnosed with prostate cancer, reports a 20-year study from Northwestern Medicine. This is the first report to show men with inflammatory bowel disease have higher than average PSA (prostate-specific antigen) values, and this group also has a significantly higher risk of potentially dangerous prostate cancer.

About 1 million men have inflammatory bowel disease in the U.S. Inflammatory bowel disease is a common chronic condition that includes Crohn’s disease and ulcerative colitis. “These patients may need to be screened more carefully than a man without inflammatory bowel disease,” said lead study author Dr...

A tumor cell that has acquired high metastatic potential during chemotherapy lights up with high FRET biosensor readout, whereas the cells that are sensitive to chemotherapy (and hence, low potential) stays dark.

Researchers engineered sensors to detect and measure the metastatic potential of single cancer cells. Metastasis is attributed as the leading cause of death in people with cancer.
Cancer would not be so devastating if it did not metastasize,” said Pradipta Ghosh, MD, professor in the UC San Diego School of Medicine departments of Medicine and Cellular and Molecular Medicine, director of the Center for Network Medicine and senior study author.

“Although there are many ways to detect metastasis once it has occurred, there has been nothing available to ‘see’ or ‘measure’ the potentia...

A mouse study shows that a single workout can activate POMC neurons (shown in green in yellow) for up to 2 days. The activity of these neurons are important regulators of blood glucose levels and energy balance.

Study offers insight into brain’s potential role in fitness, diabetes therapy. A new study from UT Southwestern Medical Center shows neurons in mice that influence metabolism are active for up to two days after a single workout. The research offers new insight into the brain’s potential role in fitness and – in the longer term – may provide a target for developing therapies that improve metabolism.

“It doesn’t take much exercise to alter the activity of these neurons,” said Dr. Kevin Williams, a neuroscientist at UT Southwestern...
