People with high cholesterol are at risk of heart attack and stroke because atherosclerotic plaques within their arteries can rupture triggering the formation of a blood clot called an occlusive thrombus that cuts off the blood supply to their heart...
A UCSF study shows a popular treatment for a potentially blinding eye infection is just as effective if given every six months versus annually. This randomized study on trachoma, the leading cause of infection-caused blindness in the world, could...
Anxious people have long been classified as "hypersensitive" -- they're thought to be more fearful and feel threatened more easily than their counterparts. But new research from Tel Aviv University shows that the anxious may not be...
Scientists have discovered a missing link between the body's biological clock and sugar metabolism system, a finding that may help avoid the serious side effects of drugs used for treating asthma, allergies and arthritis. In a paper published last...
When evaluating early kidney injuries in people, doctors monitor blood level increases of creatinine, a waste product of muscle breakdown, to understand the severity of the injury. Creatinine is filtered by the kidneys, and small increases are an...
Statins, traditionally known as cholesterol-lowering drugs, may reduce mortality among patients hospitalized with influenza, according to a new study released online by The Journal of Infectious Diseases. It is the first published observational...
Researchers at the Institute for Research in Biomedicine (IRB Barcelona) have identified the gene GATA 6 as responsible for epithelial cells -which group together and are static- losing adhesion and moving towards a new site. This process, which is...

Cancer of the liver -- rare in the United States but the third-leading cause of cancer death worldwide -- can result from environmental exposures or infections like chronic hepatitis, but the link is poorly understood. Now, researchers at Dana-...
New research by scientists at The Scripps Research Institute has underlined the power of an endogenous anti-stress peptide in the brain to prevent and even reverse some of the cellular effects of acute alcohol and alcohol dependence in animal models...
Researchers at Rensselaer Polytechnic Institute have developed a new method to design antibodies aimed at combating disease. The surprisingly simple process was used to make antibodies that neutralize the harmful protein particles that lead to...
An unusual regulatory mechanism that controls the swimmer/non-swimmer option in genetically identical Salmonella also impacts the bacteria's ability to cause infection. University of Washington scientists reported the discovery this week in the...
Researchers at the University of Gothenburg's Sahlgrenska Academy have discovered a brand new tick-borne infection. Since the discovery, eight cases have been described around the world, three of them in the Gothenburg area, Sweden. In July 2009 a...
A new analysis of national survey data finds that less than one-quarter of parents of overweight children recall ever being told by a doctor or other health care provider that their children were overweight. And although that percentage has...
In pets and people, the time it takes to diagnose an infection may mean life or death. Now, a University of Missouri veterinarian is identifying ways to diagnose pet infections in approximately a third of the current diagnosis time. The resulting...
Lymphedema, a chronic swelling condition common in breast cancer survivors, affects three million people in the U.S. In the past, most people believed that exercise might induce or worsen lymphedema. After reviewing the literature, University of...
Over the past year, researchers at the California Institute of Technology (Caltech), and around the world, have been studying a group of potent antibodies that have the ability to neutralize HIV in the lab; their hope is that they may learn how to...
Scientists at Joslin Diabetes Center in Boston have uncovered important molecular and genetic keys to the development of soft-tissue sarcomas in skeletal muscle, giving researchers and clinicians additional targets to stop the growth of these often...
It looks like bone. It feels like bone. For the most part, it acts like bone. And it came off an inkjet printer.
Washington State University researchers have used a 3-D printer to create a bone-like material and structure that can be used in...
A drug commonly used to treat seizures appears to make eye tumors less likely to grow if they spread to other parts of the body, according to researchers at Washington University School of Medicine in St. Louis. Their findings are available online...
An international team of researchers has reviewed the evidence linking exposure to atrazine -- an herbicide widely used in the U.S. and more than 60 other nations -- to reproductive problems in animals. The team found consistent patterns of...
