Through a complex analysis of protein interactions, researchers from IRB Barcelona and the Joint Programme IRB-BSC have discovered new molecular mechanisms that may be involved in the development of Alzheimer's disease. The study, a collaboration between bioinformaticians and cell biologists, was led by IRB Barcelona group leader and ICREA researcher Patrick Aloy and appears today in the Genome Research, a reference journal in the field of genomics.

INDIANAPOLIS –While many studies have looked at the treatment of chronic pain from the patient's perspective, there has been little research on those who provide care for chronic pain.
In a new report that bucks the concerns raised by the Food and Drug Administration, a Boston University School of Public Health (BUSPH) (sph.bu.edu) researcher concludes that electronic cigarettes are much safer than real cigarettes and show promise in the fight against tobacco-related diseases and death.
A new study by German researchers found that a variation in the PNPLA3 (adiponutrin) gene was associated with cirrhosis of the liver and elevated transaminase (liver enzyme) levels in alcoholic Caucasians. The risk of cirrhosis in alcoholics in the genetic high risk group might be as high as 25% to 50%. Full findings are published in the January 2011 issue of Hepatology, a journal of the American Association for the Study of Liver Diseases.
DURHAM, N.C. -- Scientists now know that some cancer cells spread, or metastasize, throughout the body the old-fashioned way -- by using their feet. But researchers at Duke Cancer Institute have discovered a way to short-circuit their travels by preventing the development of these feet, called invadopodia. This discovery is even more important because preventing the development of these "feet" also eliminates the action of proteins present in the feet that burn through intact tissue and let cancer cells enter new cells.
Researchers from Italy determined that radiofrequency ablation (RFA) is a safe and effective therapy for managing hepatocellular carcinoma (HCC) in cirrhotic patients. The high repeatability of RFA is advantageous in controlling recurrences of cancerous tumors in the liver. Results of this 10-year retrospective study are available in the January 2011 issue of Hepatology, a journal published by Wiley-Blackwell on behalf of the American Association for the Study of Liver Diseases (AASLD).
Washington, DC – The Presidential Commission for the Study of Bioethical Issues today released its first report—a wide-ranging review of the emerging field of synthetic biology—issuing 18 recommendations including a call for coordinated federal oversight of scientists working in both large institutions and smaller settings.
If everyone in the UK ate their "five a day," and cut their dietary salt and unhealthy fat intake to recommended levels, 33,000 deaths could be prevented or delayed every year, reveals research published online in the Journal of Epidemiology and Community Health.
Eating five portions of fruit and vegetables a day accounts for almost half of these saved lives, the study shows. Recommended salt and fat intakes would need to be drastically reduced to achieve similar health benefits, say the authors.
America is winning a battle against heart disease and stroke mortality, but is still losing the war, according to the American Heart Association.
In Heart Disease and Stroke Statistics – 2011, published online in Circulation: Journal of the American Heart Association, the association reports that the death rate from heart diseases declined 27.8 percent from 1997 to 2007 (the most recent final data available), and the stroke death rate fell 44.8 percent.
Body fat distribution does not play an important role in the incidence of every subtype of premenopausal breast cancer, but is associated with an increased risk for estrogen receptor (ER)–negative breast cancer, according to a study published December 15 in The Journal of the National Cancer Institute.
New research findings appearing in the January Journal of Lipid Research indicate that compounds called oxysterols are not present in any significant amount in multiple sclerosis patients, contradicting a previous study that suggested that some of these cholesterol metabolites were associated with MS and could be used as diagnostic tools in the clinic.
New York, NY, December 15, 2010 – There is burgeoning public interest in possible wide-ranging health benefits from vitamin D, including cardiovascular health. In a study published in the December 2010 issue of The American Journal of Medicine, investigators found that there was no independent association between serum levels of vitamin D or parathyroid hormone and cardiovascular mortality in this prospective study, the first in a population of older community-dwelling adults with a low prevalence of vitamin D deficiency and a broad range of kidney function.
