High blood pressure, low energy -- a recipe for heart failure
...s died. They also saw that the hearts had depleted fuel
reserves. Kelly indicates that these studies show for the first time that changes in the ability of the heart to produce energy lead to heart failure in some cases. "ERR and some of its partners in the cell are a little like puppeteers controlling t...
Abnormal fat metabolism underlies heart problems in diabetic patients
...diabetes. "Diabetic hearts run mostly on fats for fuel
because glucose isn't readily available to them," says Richard Gross, M.D., Ph.D., director of the Division of Bioorganic Chemistry and Molecular Pharmacology and professor of medicine, of chemistry and of molecular biology and pharmacology. "Unfortu...
No evidence that widely prescribed statins protect against prostate cancer

cancer growth. Researchers from the New England Research Institutes found that while men using statins did indeed have lower blood levels of androgens such as testosterone, it was more likely attributable to poor health rather than the use of s...

prostate cancer. Androgen deprivation is a common therapy for prostate cancer. Knowing which gene fusion is involved in an individual patients tumor could impact treatment options. If an androgen-regulated gene is involved, androgen therapy would b...
Nanotechnology helps scientists make bendy sensors for hydrogen vehicles
