STANFORD, Calif. — Researchers at the Stanford University School of Medicine, in collaboration with BioParadox, Inc., have published data supporting the use of platelet-rich plasma as a promising biologic treatment for myocardial infarction (heart…
(ORLANDO, December 5, 2010) — The next generation of drug therapies and enhanced treatment approaches for various forms of lymphoma are evolving as researchers continue to better understand how these cancers progress. Research will be presented to…
People getting a minimal amount of sleep do better if they go to bed early in the morning rather than late at night, suggests Stanford University Medical Center research. A recently published pilot study on the effects of sleep deprivation also found that individual tolerance of sleep restriction varies widely, yet study participants had a better overall adaptation to early morning sleep.
Scientists have finally laid hands on the first member of a recalcitrant group of proteins called the Wnts two decades after their discovery. Important regulators of animal development, these proteins were suspected to have a role in keeping stem cells in their youthful, undifferentiated state – a suspicion that has proven correct, according to research carried out in two laboratories at Stanford University Medical Center. The ability to isolate Wnt proteins could help researchers grow some types of stem cells for use in bone marrow transplants or other therapies.
A population of Jewish people known as the Ashkenazi Jews have an unusually high risk of several genetic diseases, and up until now, no one has understood why. Was it random chance that made mutations so common or did evolution play a role in keeping mutations around? The answer to this question, said researchers at Stanford University Medical Center, appears to be chance. Their findings appear in the March online issue of the American Journal of Human Genetics and in the journal’s April print edition.
Drug addicts may prefer some drugs over others, but their brains all have something in common. Whether it’s uppers or downers, addictive drugs tweak the same addiction-related neurons, causing them to become more sensitive, say researchers at Stanford University Medical Center. “What we have identified is a single change caused by drugs of abuse with different molecular mechanisms,” said researcher Robert Malenka.
Researchers have published new evidence showing that cells from the bone marrow might help repair or maintain cells in other tissues. In a paper in this week’s online edition of the Proceedings of the National Academy of Sciences, the researchers describe finding chromosomes from a bone marrow transplant in the brain cells of transplant recipients. When people receive a bone marrow transplant after high-dose chemotherapy, some of the transplanted cells regenerate the blood-making cells that were destroyed. In past experiments in mice, scientists found that cells from the transplant could also relocate to tissues throughout the body rather than being restricted to the bone marrow and blood.
Researchers have found that a recently discovered gene regulates HDL (high density lipoproteins) cholesterol, also known as “good” cholesterol. The study, published in the February issue of the Journal of Clinical Investigation, could lead to new therapies for heart disease, said lead author Thomas Quertermous, MD. “This is a significant and unexpected finding, and the gene is going to be a real target for the prevention and treatment of heart disease,” said Quertermous, the William G. Irwin Professor and chief of cardiovascular medicine at Stanford University School of Medicine. “This type of thing doesn’t happen every day.”
Past studies have shown that various medications including beta blockers and aspirin can help manage heart disease. Yet a new study from Stanford University Medical Center indicates physicians continue to underprescribe these key treatments. The study appears in the Jan. 1 issue of the Journal of the American College of Cardiology. It focuses on the outpatient use of the drug warfarin for atrial fibrillation (or irregular heartbeat), beta blockers and aspirin for coronary artery disease, and ACE inhibitors for congestive heart failure – all medications that have been shown to benefit patients in past clinical trials and population studies.
For some, the holiday season brings an annual rite that may feel like “compulsive shopping,” but for others, compulsive shopping is a year-round illness that seriously interferes with daily life. People with a compulsive shopping disorder often are unable to think about anything other than shopping and can’t control the impulse to purchase even useless or unwanted items. Stanford University Medical Center is continuing a multi-year clinical trial on a medication that may curb this irresistible urge.
