Although moderate alcohol intake is associated with lower risk for myocardial infarction (MI), guidelines generally suggest that adults seek other lifestyle measures to reduce cardiovascular risk. Physical activity, smoking, and diet, moderate alcohol intake is associated with lower risk for MI.
Grape seed extract significantly inhibited the growth of colorectal tumors in both laboratory cell cultures and in mice, U.S. researchers report. A team from the University of Colorado Health Sciences Center in Denver says mice given the extract displayed a 44 percent reduction in the size of advanced colorectal tumors.
Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and the University of California at Berkeley have developed a new technique for Magnetic Resonance Imaging that allows detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques. Called HYPER-CEST, this technique could become a valuable tool for medical diagnosis, including the early detection of cancer.
A protein known to play a role in blood clotting and other cell functions is also critical for proper sperm formation in mice, according to researchers from the University of North Carolina at Chapel Hill School of Medicine.
The link between short sleep duration and obesity: We should recommend more sleep to prevent obesity. Soaring levels of obesity might be linked to children sleeping fewer hours at night than they used to, claims a researcher in the Archives of Disease in Childhood.
The cornea stays clear by expressing a soluble form of a receptor that traps factors enabling growth of vision-obstructing blood vessels, researchers say. When sflt-1, a free-floating receptor for vascular endothelial growth factor A, is eliminated, vision-obstructing blood vessels start growing, teams of researchers led by the Medical College of Georgia and University of Kentucky report in Nature. The paper was published online Oct. 18 and will be in the Oct. 26 print issue.
Certain types of brain cancer cells, called cancer stem cells, help brain tumors to buffer themselves against radiation treatment by activating a “repair switch” that enables them to continue to grow unchecked, researchers at Duke University Medical Center have found.
UT Southwestern Medical Center is one of a handful of top research institutions evaluating a promising new medication researchers hope can reduce the severity and frequency of asthma attacks in inner-city children, a population known to have a high prevalence of severe asthma.
Researchers in the Greene Infectious Disease Laboratory at Columbia University’s Mailman School of Public Health, the Centers for Disease Control and Prevention, and the Caribbean Primate Research Center have discovered a key mechanism by which the Filoviruses, Ebola and Marburg, cause disease. The identification of an amino acid sequence in Filoviruses that results in the rapid depression of immunological response is described in the December 2006 issue of The FASEB Journal. Using this information, researchers can begin to develop new drugs to stop these devastating diseases.
Soot particles spewing from the exhaust of diesel trucks constitute a major contributor to the alarmingly high rates of asthma symptoms among school-aged children in the South Bronx, according to the results of a five-year study by researchers at New York University’s School of Medicine and Robert F. Wagner Graduate School of Public Service.
