Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

... interventions. The paper is intended to be an example of best practice for reporting such studies. Guidelines laying out minimum requirements for data recording, statistical analysis, and reporting are contained in the consensus statement for infection control studies---labelled the ORION (Outbreak Repo...

Genes and genius: Researchers confirm association between gene and intelligence

...rrectly to tell a story," Dick explains. "A simple example might be pictures of a child holding a vase, the vase broken to bits on the floor and the child crying. The person taking the test would have to put those pictures into an order that tells the story of how the child dropped the vase and broke it and ...

New approach could lower antibiotic requirements by 50 times

...ntibiotic effectiveness. 'Pseudomonas bacteria for example are particularly multi-resistant to antibiotics be... (Methicillin-resistant Staphylococcus aureus) for example is rapidly spreading through hospitals, affecting more than 8,000 people in the UK every year. MRSA ...

Ape gestures offer clues to the evolution of human communication

...n the last common ancestor," said Pollick. "A good example of a shared gesture is the open-hand begging gesture, used by both apes and humans. This gesture can be used for food, if there is food around, but it also can be used to beg for help, for support, for money and so on. It's meaning is context-depende...

Virginia Tech's System X supercomputer provides super tool for simulation of cell division

...tion of what is going on inside the cell. A simple example is the conversion between Fahrenheit and Celsius temperatures, said mathematician Layne Watson. "You could use several pairs of Fahrenheit and Celsius readings for the same temperature, and try to deduce the formula for converting between the tempera...

Endangered shortnose sturgeon saved in Hudson River

... evidence for a large and secure population are an example of successful protected species management," said Bain. "Scientists and legislators have called for changes in the U.S. Endangered Species Act; the act is being debated in Congress and has been characterized as failing to recover species." However,...

St. Jude announces breakthrough in eye cancer treatment

...ocking out MDMX with nutlin-3 represents the first example of local delivery of a targeted chemotherapy drug for any childhood cancer, Dyer said. Targeted therapy uses a customized drug to disable a specific molecule inside a growing cancer cell; local delivery is the placement of a drug at the site of di...

Plant studies reveal how, where seeds store iron

...n called ferritin. "This project is a wonderful example of the power of using new combinations of tools--in this case, genetics and high-resolution 3-dimensional X-ray fluorescence imaging--to understand gene function," said Jane Silverthorne, a program director in NSF's Division of Biological Infrastruct...

Living view in animals shows how cells decide to make proteins

...in different tissues," he said. "It’s an excellent example of how experiments in living organisms provide a much more complete picture of how genes and proteins behave than do experiments using cells in culture." Until 20 years ago, scientists believed that a single gene made a single protein. With the d...

New gene linked to bipolar disorder

...der, including possible preventive strategies, for example with drugs or even through nutritional intervention." Around one in every 200 people in the UK develops bipolar and other related mood disorders. Signs of depression include losing weight, feeling totally negative about oneself, feel hopeless abou...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

... period of rapid discovery. "This provides a clear example of how basic fundamental research can contribute to treatment of blinding diseases," he says. "We now have proof of principle that our approach to repairing damaged retina by transplantation of appropriate cells can be successful." Swaroop sees s...

Study uncovers mutation responsible for Noonan Syndrome

... PTPN11 mutations. "These results are the first example of activating mutations in an exchange factor in human disease," notes Neel, explaining that for families at risk for Noonan syndrome, the findings will aid in prenatal diagnosis and genetic counseling for the disorder. "Furthermore," Neel adds, "...

Scientists show drug can counteract muscular dystrophy in mice

... inhibitor and healthy mice. "This is the first example of using a drug to counteract muscular dystrophy in mouse models," says Dr. Sartorelli. Yet he points out that the drug is only promoting muscle regeneration ?it is not curing the defect that causes muscle deterioration. Further studies are needed t...

Edible coatings will be the packaging of the future

...dible coating of fruit is currently the best-known example of the application. However, it is a packaging system particularly efficacious for conserving foodstuffs that are high in polysaturated fatty acids, susceptible to oxidation, such as nuts, meat and certain fish such as salmon. In his PhD, Javier Os...

Common ancestry of bacterium and plants could be key to an effective new treatment for chlamydia

...ok College). "But we have now described a specific example demonstrating the common heritage. That specific example, an enzyme that supports protein production, could lead to antibiotics specific for this form of STD." The discovery is an unexpected turn in solving the mystery of how plants produce lysine...

Proteins necessary for brain development found to be critical for long-term memory

...nt of Neurobiology and Behavior. "It is a striking example of how molecular rules employed in building a brain are often reused for different purposes throughout a lifetime." The researchers have shown that proteins known as growth factors are as essential for the induction of long-term memory as they are ...

BC catalyst discovery promises faster, cheaper drug production

...ve processes for manufacturing drugs. It's a great example of how NIH support for fundamental chemical research can benefit the American health care consumer," said John M. Schwab, a chemist at the National Institute of General Medical Science,which supported the work. ...

Hopkins researchers discover how brain protein might control memory

...by an act as simple as exploring new environs, for example - causes the cells to make more Arc protein almost immediately. "Arc is an instant and reliable readout for active cells in the brain," says Worley. But although scientists knew that active cells were making copious amounts of Arc, no one knew exactl...
