People older than 60 with high blood pressure are less likely than other groups of patients to receive advice from their doctors about lifestyle modifications that can help lower their blood pressure, a study by UNC researchers concludes.
Platinum complexes such as the well-known cisplatin are powerful antitumor medications. They cross the cell membrane and reach the nucleus, where they attach to DNA and stop cell growth. But how does cisplatin get to the nucleus? Italian researchers have now proven that a copper transport protein may play a critical role. In the journal Angewandte Chemie, they present their hypothesis about the transport mechanism.
Cancer cells treated with carbon nanotubes can be destroyed by non-invasive radio waves that heat up the nanotubes while sparing untreated tissue, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center and Rice University has shown in preclinical experiments.
Orthopedic researchers at Jefferson Medical College have for the first time found stem cells in the intervertebral discs of the human spine, suggesting that such cells might someday be used to help repair degenerating discs and remedy lower back and neck pain.
The Autism Consortium, a group of researchers, clinicians and families dedicated to radically accelerating research and enhancing clinical care for autism, announced that it has completed the first genome scan for Autism Spectrum Disorders (ASD) through its Autism Gene Discovery Project and has released the reference data set to a database that autism researchers around the world can use. The scan was conducted using new, high resolution technology developed by Affymetrix on genetic data from more than 3,000 children with ASD and their families.
It’s almost flu season, so keep washing your hands and get a flu shot. But no matter how well we prepare, the virus stays one step ahead. Researchers now think that’s because the flu virus doesn’t vacation—it remains on duty throughout the year, traveling the globe and mixing with other strains.
Eating garlic is one of the best ways to lower high blood pressure and protect yourself from cardiovascular disease. A new study from the University of Alabama at Birmingham (UAB) shows this protective effect is closely linked to how much hydrogen sulfide (H2S) is produced from garlic compounds interacting with red blood cells.
More than 40 Lawrence Livermore National Laboratory employees are key scientific contributors to the reports of the Intergovernmental Panel on Climate Change, which today, along with former Vice President Al Gore, won the 2007 Nobel Peace Prize.
In a move that is viewed as a major step toward developing a secure and portable health information system for all Americans, the U.S. Department of Health and Human Services has awarded the Indiana University School of Medicine a $2.5 million contract to begin a trial implementation of a Nationwide Health Information Network.
At the Keystone Symposium in Cape Town, the Global HIV Vaccine Enterprise announced the appointment of its first executive director and the opening of a new secretariat in New York City. Dr. Alan Bernstein, founding president of the Canadian Institutes of Health Research, will lead the international alliance of researchers, funders and advocates dedicated to speeding the search for an HIV vaccine.
