Preventing a pandemic: Study suggests strategies for containing a flu outbreak

...t the many things that could go wrong, researchers say that it may be possible to contain a Southeast Asian outbreak of avian influenza in humans, buying precious time for the production of a vaccine. Using a computer model to simulate an outbreak in a rural Southeast Asian population, the scientists ha...

Software 'agents' could help unmask reality of disease clusters

... identity of individual patients. But researchers say that these measures often make it impossible for them to carry out accurate geographical analyses of public health concerns, and may even result in misleading information being used in healthcare decisions. They suggest that new technology which use...

"So I think it's fair to say the POMC neurons gained in stature during the last 10 years as being really important to feeding; meanwhile, the importance of the NPY pathway diminished. To some extent, the field began to think these cells were supporting players, but not really im...

Scientists closer to new cancer detection method

University of Florida researchers say they are a step closer to a technique to easily detect a wide variety of cancers before symptoms become apparent. The findings, currently online in the Proceedings of the National Academy of Sciences, involve introducing molecularly engineered stran...

Emerging staph strains found to be increasingly deadly and deceptive

...and are increasing nationally at an alarming rate, say experts. Scientists at NIAID's Rocky Mountain Laboratories (RML) in Hamilton, MT, and colleagues examined the ability of MRSA strains to cause disease in mice and avoid destruction by human white blood cells called neutrophils.

Gene therapy reverses genetic mutation responsible for heart failure in muscular dystrophy

...25 edition of the journal Circulation, the authors say that this is the first successful attempt to deliver a therapeutic gene throughout the body. "Previous attempts at systemic gene therapy for muscle have not been very effective because blood vessel capillaries act much like a mosquito net, blocking ...

Human cerebellum and cortex age in very different ways

...rns of aging evolve very rapidly." The scientists say their results may cast some doubt on the effectiveness of mice and other species to model various types of neurodegenerative disease: If human and chimpanzee brains age in markedly dissimilar ways, the difference between humans and more distantly rel...

Gene therapy works in mice to prevent blindness that strikes boys

...ed to be able to read or walk around." Scientists say the gene transfer method eventually could be applied to many eye diseases caused by single gene defects, including a host of retinal disorders. Retinoschisis is usually first detected in boys between 5 and 10 years of age when their vision problems ...

Customized gene chip provides rapid detection of genetic changes in children's cancer

...l of Philadelphia and Thomas Jefferson University, say their technique may be readily adapted for other types of cancer. The proof-of-principle study appears in the August issue of Genome Research. One advantage of their technique is its flexibility, said co-author John M. Maris, M.D., a pediatric oncol...

According to Ann Brooks Gould, associate extension specialist at Rutgers University, New Brunswick, NJ, bacterial leaf scorch (BLS) affects many shade tree species such as Ameri...

Anti-cancer Compound In Beer Gaining Interest
