Scientists develop 'barcode chip' to revolutionize diagnostic medical testing

In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease.

Adiponectin is a metabolic link between obesity and bone mineral density

Researchers at the University of Toronto, Faculty of Medicine, Toronto, Canada, have discovered that adiponectin, a protein secreted from adipocytes, is a metabolic link that can explain, in part, the known positive relationship between obesity and both bone mineral density and reduced susceptibility to fractures.

Presence of gum disease may help dentists and physicians identify risk of cardiovascular disease

Individuals reporting a history of periodontal disease were more likely to have increased levels of inflammation, a risk factor for heart disease, compared to those who reported no history of periodontal disease, according to an American Journal of Cardiology report available online today.

Understanding how oxidative stress impairs endothelial progenitor cell function may lead to antioxidant therapy to prevent cardiovascular disease

Although its been over a decade since endothelial progenitor cells or EPCs, cells that circulate in the blood repairing and replacing the cells that line blood vessels, were identified, the field is still evolving. EPCs are now being studied as biomarkers to assess the risk of future cardiovascular disease and as potential agents for vascular regeneration.

$2.7 million boosts effort to create the big view of cancer

Many scientists like to discuss how each form of cancer is a distinct disease with its own causes and its own treatments. But researcher Hartmut "Hucky" Land, Ph.D., takes the opposite approach: He is hunting for the most basic rules that all cancers share to make good cells go bad.

Researchers find clue to safer obesity drugs

Once hailed as a miracle weight-loss drug, Fen-phen was removed from the market more than a decade ago for inducing life-threatening side effects, including heart valve lesions. Scientists at UT Southwestern Medical Center are trying to understand how Fen-phen behaves in the brain in order to develop safer anti-obesity drugs with fewer side effects.

Mammograms may pick up breast cancers which would have disappeared

According to researchers in Norway mammograms may detect some cancers that would have otherwise regressed.

Blood transfusions increase clot risk in hospitalized cancer patients

Blood transfusions used to treat anemia in patients with cancer are associated with an increased risk of life-threatening blood clots, at a similar rate as other treatments for cancer-induced anemia, according to scientists at the University of Rochester Medical Center.

Telephone counseling may be as effective as face-to-face counseling in weight loss maintenance

Face-to-face and telephone follow-up sessions appear to be more effective in the maintenance of weight loss for women from rural communities compared with weight loss education alone, according to a report in the November 24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Discovery of novel approach to suppress prostate cancer progression

Researchers at the University of Southern California (USC) have found that inactivating a specific biomarker for aggressive prostate cancer blocks the development of prostate cancer in animal models.

Pancreatic duct cells identified as new source of insulin-producing cells

Researchers at the Joslin Diabetes Center have shown that insulin-producing pancreatic beta cells can form after birth or after injury from progenitor cells within the pancreas that were not beta cells, a finding that contradicts a widely-cited earlier study that had concluded this is not possible.
