Working with heart attack-stricken mice, a team of University of Wisconsin-Madison scientists has shown embryonic stem cells can help heal heart tissue. A research team led by UW-Madison stem cell researcher Timothy Kamp reports embryonic stem cells transplanted into mouse hearts damaged by experimentally induced heart attacks, morph into functional forms of the major types of cells composing the healthy heart.
A 20-year study of people with type 1 diabetes shows that tight control of blood sugar levels cuts their risk of heart disease by more than half. The new research, published in the Dec. 22 New England Journal of Medicine, is “a landmark study,” according to Dr. William T.
Bee sting therapy is not effective in treating the symptoms of multiple sclerosis (MS), and does not improve quality of life, according to the first controlled study to investigate the alternative treatment in MS patients.
An increase in exposure to ultraviolet radiation as result of ozone depletion in the stratosphere could in future lead to a considerable increase in the incidence of cataracts in the US population, researchers report.
When Dr. Daniel S. Berman and his team at Cedars-Sinai Medical Center in Los Angeles reviewed the medical records of 17,991 patients who had taken stress tests, the researchers found that patients reporting shortness of breath were significantly more likely to die within the next few years.
When Dr. Bin Ye of Brigham and Women’s Hospital in Boston, and team, compared more than 600 women with ovarian cancer to 640 healthy controls, the investigators found that among the five most commonly used herbal supplements – ginkgo, echinacea, St. John’s Wort, ginseng, and chondroitin – only ginkgo was associated with a significantly reduced risk of developing ovarian cancer.
The results of a study of older adults suggest that people who have an under active thyroid, or hypothyroidism, but with no symptoms, have an increased the risk of congestive heart failure, but not other cardiovascular disease or death.
A team from Harvard Medical School found one year of breastfeeding was associated with a 15% drop in a woman’s risk of developing type 2 diabetes.

A new study suggests that ovarian tumors classified as serous borderline or low malignant potential (LMP) are not early precursors in the development of aggressive ovarian cancer, but may instead be part of an entirely different class of tumors. Furthermore, genes that were identified in this study as being expressed, or active, in these different classes of tumors could help identify targets for more specific diagnostics and therapies to treat this disease.
