Why Coffee Protects Against Diabetes

*Researchers discover molecular mechanism behind drink’s prophylactic effect*

Coffee, that morning elixir, may give us an early jump-start to the day, but numerous studies have shown that it also may be protective against type 2 diabetes. Yet no one has really understood why.

Now, researchers at UCLA have discovered a possible molecular mechanism behind coffee’s protective effect. A protein called sex hormone–binding globulin (SHBG) regulates the biological activity of the body’s sex hormones, testosterone and estrogen, which have long been thought to play a role in the development of type 2 diabetes. And coffee consumption, it turns out, increases plasma levels of SHBG. (more…)

Schizophrenia is a mental disorder that differs between the sexes in terms of age at onset, symptomatology, response to medication, and structural brain abnormalities. Now, a new study from the Université de Montréal shows that there is gender difference between men and women’s mental ability – with women performing better than men. These findings, published recently in, Schizophrenia Research, have implications for the more than 300 000 affected Canadians.

“We are the first to report sex differences in brain function of schizophrenics,” says Université de Montréal professor, Adrianna Mendrek a researcher at the Centre de Recherche Fernand-Seguin, Hospital Louis-H Lafontaine. “We chose to study a task involving mental rotation of a three dimensional image because in healthy men and women, this consistently elicits differences in terms of reaction time and performance accuracy.” (more…)

Tamas Horvath is the first to tell you that he doesn’t study obesity. But his research on the effects of metabolism on higher brain functions could provide deeper understanding of the brain’s link to appetite, weight and to metabolic disorders such as diabetes and obesity.

His lab was the first to provide evidence that the brain uses fat as fuel. Horvath has also studied how endocrine signals in the brain regulate neurodegenerative diseases such as Parkinson’s and Alzheimer’s.

Horvath followed his father and grandfather into veterinary medicine in his native Hungary, but his training sparked a passion for basic research. His achievements have earned him a long title that speaks to his varied research interests. He became chair of the Department of Comparative Medicine at Yale School of Medicine in 2005, and he is also a professor in the Departments of Obstetrics, Gynecology & Reproductive Sciences and Neurobiology. Horvath also heads the Program on Integrative Cell Signaling and the Neurobiology of Metabolism. (more…)

New Study Indicates Higher than Predicted Human Exposure to the Toxic Chemical Bisphenol A or BPA

COLUMBIA, Mo. – Researchers have discovered that women, female monkeys and female mice have major similarities when it comes to how bisphenol A (BPA) is metabolized, and they have renewed their call for governmental regulation when it comes to the estrogen-like chemical found in many everyday products.

COLUMBIA, Mo. – Progestins are used in hormone replacement therapies to counteract the negative effects of estrogen on the uterus and reduce the risk of uterine cancer.

However, evidence in recent studies and clinical trials has demonstrated that progestins increase the risk of breast cancer.
