(Duke University Medical Center) Tuning in to tune out may be just what's needed for men undergoing a prostate biopsy, according to researchers at the Duke Cancer Institute.

(Duke University Medical Center) Infectious films of Staph bacteria around an implanted cardiac device, such as a pacemaker, often force a second surgery to replace the device at a cost of up to $100,000.

But not all implanted cardiac devices become infected.

(Duke University Medical Center) A large-scale trial finds that apixaban, a new anticoagulant drug, is superior to the standard drug warfarin for preventing stroke and systemic embolism in patients with atrial fibrillation.

Moreover, apixaban results in substantially less bleeding and also results in lower mortality.

(Duke University Medical Center) Cancer cells circulating in the blood carry newly identified proteins that could be screened to improve prognostic tests and suggest targets for therapies, report scientists at the Duke Cancer Institute.

Building on current technologies that detect tumor cells circulating in blood, the Duke team was able to characterize these cells in a new way, illuminating how they may escape from the originating tumors and move to other locations in the body.

(Duke University Medical Center) A major discovery about an enzyme's structure has opened a window on understanding DNA repair.

Scientists at Duke University Medical Center have determined the structure of a nuclease that will help scientists to understand several DNA repair pathways, a welcome development for cancer research.

(Duke University Medical Center) The Duke Human Vaccine Institute today announced a collaboration and strategic agreement with Novartis Vaccines and Diagnostics to enable the rapid development of a vaccine and accelerate preparedness in case of a pandemic virus threat such as pandemic influenza.

(Duke University Medical Center) Cancer prevention experts have long been frustrated by the lack of a meaningful way to screen women for ovarian cancer.

It is a relatively rare disease that often progresses with few symptoms until it is too late for potentially curative treatments, and elevated values of the most commonly used biomarker used in screening, CA125, are also related to other disorders.

(Duke University Medical Center) Researchers have been stymied for years over the fact that people infected with the AIDS virus do indeed produce antibodies in response to the pathogen -- antibodies that turn out to be ineffective in blocking infection.

Now, scientists at Duke University Medical Center can explain why: Some of the earliest and most abundant antibodies available to fight HIV can't actually "see" the virus until after it's already invaded a healthy cell.

(Duke University Medical Center) The National Institutes of Health (NIH), National Institute of Allergy and Infectious Diseases (NIAID), has awarded Duke University Medical Center up to $52.8 million over the next seven years to support the development, implementation and oversight of external quality assurance programs that monitor laboratories involved in HIV/AIDS research and vaccine trials around the world.
