US continues to lag behind other nations when it comes to gains in life expectancy: Study

America continues to lag behind other nations when it comes to gains in life expectancy, and commonly cited causes for our poor performance-obesity, smoking, traffic fatalities and homicide-are not to blame, according to a study by researchers at Columbia University's Mailman School of Public Health.

Study finds boosting mitochondria may delay onset of Parkinson's disease

In a study that sheds new light on the causes of Parkinson's disease, researchers report that brain cells in Parkinson's patients abandon their energy-producing machinery, the mitochondria. A shutdown in fuel can have devastating effects on brain cells, which consume roughly 20 percent of the body's energy despite making up only 2 percent of body weight.

Scientists engineer bacterial cell wall with small molecules to combat diseases

A team of Yale University scientists has engineered the cell wall of the Staphylococcus aureus bacteria, tricking it into incorporating foreign small molecules and embedding them within the cell wall.

Vanderbilt-Ingram Cancer Center receives $7.6M ARRA stimulus grant for prostate cancer research

Vanderbilt-Ingram Cancer Center has received a $7.6 million American Recovery and Reinvestment Act of 2009 stimulus grant to coordinate a study comparing the effectiveness of various treatments for prostate cancer. David Penson, M.D., M.P.H., professor of Urologic Surgery, will serve as Principal Investigator for the Comparative Effectiveness Analysis of Surgery and Radiation study on prostate cancer.

Two-day symposium marks an extraordinary decade for Brown Institute for Brain Science

Just as intense concentration allows a sharp mind to perform at its peak, a research institute that concentrates pre-eminent scientists from 11 academic departments can push back the frontiers of knowledge in a complex research area: the human brain.

Researchers find significant difference between prevalence of tinnitus among elderly people

Tinnitus is common among elderly Nigerians and associated with treatable health conditions like otitis media, rhinosinusitis, head injury and hypertension, according to new research published in the October 2010 issue of Otolaryngology - Head and Neck Surgery.

Researchers identify molecular mechanism that regulate metastasis of melanoma cells

The way melanoma cells use the immune system to spread and develop into lung tumors may lead to a therapy to decrease development of these tumors, according to Penn State researchers.

Intestinal bacteria send signals that promote cell proliferation in Wnt signaling pathway

Microbes matter -- perhaps more than anyone realizes -- in basic biological development and, maybe, they could be a target for reducing cancer risks, according to University of Oregon researchers.

NIAID announces three new contracts to fund research on dengue, anthrax vaccines

The National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, today announced three new contracts to fund research on vaccines to protect against emerging infectious diseases and biological threats that could be used in a terror attack. Each project focuses on simple and efficient vaccine delivery approaches that could be deployed quickly. The total funding for the three contracts could reach $68 million, depending on the successful completion of defined project milestones.

Matchmaker function may help cardiologists understand the natural repair process after heart attacks

Heart muscle cells do not normally replicate in adult tissue, but multiply with abandoned during development. This is why the loss of heart muscle after a heart attack is so dire-you can't grow enough new heart muscle to make up for the loss.

Study finds relationship between bacterial infections, acute asthma attacks in children

"We found a significant relationship between bacterial infections and acute asthma attacks - above and beyond the expected relationship between viral infections and attacks," says Hans Bisgaard, a professor of paediatrics at the DPAC.

Prostate cancer updates

Scientists have found that genetic variations for an enzyme involved in cell energy metabolism may increase the risk of prostate cancer. This variation in genes may impair the enzyme phosphodiesterase 11A (PDE11A), which helps regulate cells' responses to hormones and other signals, according to the U.S. National Institute of Child Health and Human Development researchers and colleagues.

Parkinson’s disease pathology breakthrough

Researchers have found that brain cells of people with early Parkinson's disease have damaged powerhouses. In a new study they have identified 10 groups of gene sets related to the energy production problems in the brain cells of these people.

Center for Injury Research and Policy awarded $38.6M to expand METRC

The Center for Injury Research and Policy at the Johns Hopkins Bloomberg School of Public Health has been awarded $38.6 million by the Peer Reviewed Orthopaedic Research Program of the U.S. Department of Defense to expand its Major Extremity Trauma Research Consortium.

Researchers shed new light about long non-coding RNA molecules

Despite progress in decoding the genome, scientists estimate that fully 95 percent of our DNA represents dark, unknown territory. In the October 1 issue of the journal Cell researchers at The Wistar Institute shed new light on the genetic unknown with the discovery of the ability of long non-coding RNA (ncRNA) to promote gene expression.

Elevated levels of iron in brain enhance brain-destroying plaque production in Alzheimer's patients: Research

Massachusetts General Hospital researchers say they have determined how iron contributes to the production of brain-destroying plaques found in Alzheimer's patients.

Blind people can use visual cortex to refine sensation: Study

People who have been blind from birth make use of the visual parts of their brain to refine their sensation of sound and touch, according to an international team of researchers led by neuroscientists at Georgetown University Medical Center (GUMC).

Paper describes new method for studying bacterial infection of orthopedic implants

A research team, co-headed by Dr. Woo Lee and Dr. Hongjun Wang of Stevens Institute of Technology, has published a paper describing a new method that generates three-dimensional tissue models for studying bacterial infection of orthopedic implants. Dr. Joung-Hyun Lee of Stevens, and Dr. Jeffrey Kaplan of the New Jersey Dental School, are co-authors of the research.

Immune reaction to dystrophin may contribute to muscle disease: Study

An immune reaction to dystrophin, the muscle protein that is defective in patients with Duchenne muscular dystrophy, may pose a new challenge to strengthening muscles of patients with this disease, suggests a new study appearing in the October 7, 2010, issue of The New England Journal of Medicine.
