The “resistance movement” founded by bacteria to combat antibiotics may be losing ground. By combining key properties of two different types of weapons used by the innate defense systems of organisms, a team of scientists at the Weizmann Institute of Science has managed to design a more powerful weapon, hoping that this will provide a basis for novel and more effective antibiotics.
In hemophilia, a mutated gene prevents the production of a blood-clotting protein. Treatments for hemophilia and other genetic diseases may consist of risky blood transfusions or expensive enzyme replacement therapy. But what if the body could be induced to begin producing these proteins by transplanting healthy tissue with the abilities that are lacking? The Weizmann Institute’s Immunology Department showed how such a transplant might be made feasible.
Medical teams — not individuals — are critical to the prevention of catheter-related bloodstream infections, as well as for the overall health, safety, and welfare of patients, according to an editorial by two Virginia Commonwealth University physicians published in today’s issue of the New England Journal of Medicine.
High blood pressure may seem like something that only adults get, but children can develop it too — and it can pose serious risks to their hearts, brains and lives. While medications may help some children, a new study shows that for kids with a rare but especially dangerous form of hypertension, surgery is the best option.
Solving a 100-year-old genetic puzzle, researchers at the UCSD School of Medicine have determined that the same genetic mechanism that drives tumor growth can also act as a tumor suppressor. Their findings could lead to new drug targets for cancer therapies.
Researchers at the National Institutes of Health have discovered that a previously unexplained fatal form of Osteogenesis Imperfecta — a disorder that weakens bones and which may cause frequent fractures — results from a genetic defect in a protein involved in the production of collagen.
Hospitals will quickly slash the rate of common, costly and potentially lethal catheter-related bloodstream infections in their intensive care units (ICUs) by using cheap, low-tech, common-sense measures like hand washing, timely removal of unneeded catheters and use of sites other than the groin to place lines when possible, according to a report from safety experts at Johns Hopkins in the Dec. 28 issue of the New England Journal of Medicine.
Despite the explosive growth in size and complexity of the human brain, the pace of evolutionary change among the thousands of genes expressed in brain tissue has actually slowed since the split, millions of years ago, between human and chimpanzee, an international research team reports in the December 26, 2006, issue of the journal, PLOS Biology.
Scientists have pinpointed a possible reason why pancreatic cancer is such an aggressive disease. Pancreatic cancer cells overexpress gelsolin family-capping proteins, which contribute to their cell motility.
Kids and adults will stay glued to video games this holiday season because the fun of playing actually is rooted in fulfilling their basic psychological needs. Psychologists at the University of Rochester, in collaboration with Immersyve Inc., a virtual environment think tank, asked 1,000 gamers what motivates them to keep playing. The results published in the journal Motivation and Emotion this month suggest that people enjoy video games because they find them intrinsically satisfying.
