Federal testing for mad cow disease a failure, law review editor says

The U.S. Agriculture Department's mad cow disease-testing program is wholly inadequate and t...cted with bovine spongiform encephalopathy, or mad cow disease, can cause Creutzfeldt-Jakob disease, a fatal human brain-wasting disorder. More than 160 de...

Prion find points way to test for human 'mad cow' disease

...any people are infected with the human form of mad cow disease, which can take as long as 40 years before manifesting itself. Such a blood test could also help prevent accidental transmission of the malformed proteins that cause variant Creutzfeldt-Jakob disease (vCJD) via blood transfusions and organ t...

Blood transfusion-transmitted infections: A global perspective

...-Jakob disease (vCJD) the human counterpart to mad cow disease. With regard to the emerging pathogens, several newly-developed pathogen-reduction technologies have been shown to be effective in destroying most bacteria, viruses and parasites in donated blood, but ineffective against the pathogens that...

Biodegradable napkin -- featuring sensitive nanofibers -- may quickly detect biohazards

...he hazard of the week, whether it is bird flu, mad cow disease or anthrax." Frey and her colleagues are still working on ways, such as a color change, for the fabric to signal that it has identified the contaminant. "We're probably still a few years away from having this ready for the real world," Frey...

U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

...ss could be used cooking oil or even products from cow manure, yard clippings, cornstalks or trees." One up-and-coming fuel is biodiesel, which is produced from soy oil. Currently, the key step in conversion of the oil to biodiesel requires the addition of methanol, a fossil fuel. The new process skip...

Prion disease treatable if caught early

...se believed to be contracted from cattle with "mad cow disease"—is caused by aberrant, infective proteins. It has been thought that the disease is untreatable. However, in previous studies with prion-infected mice, Mallucci and colleagues found that early brain degeneration can be reversed if prions a...

Brown team finds crucial protein role in deadly prion spread

...ntially slow the spread of prions, which cause mad cow disease and scrapie in animals and, in rare cases, Creutzfeldt-Jacob disease and kuru in humans. Because similar protein replication occurs in Alzheimer's and Parkinson's diseases, such a drug could also slow progression of these diseases as well....

Synthetic peptide targets latent papilloma virus infections

...an and numerous other researchers on the human and cow (bovine) papilloma virus has shown how the virus moves into new cells. It carries its genes in the form of a circular DNA plasmid that nestles in the nucleus of the cell and makes use of the cellular machinery to generate more copies of itself. Each ...

Mimicking how the brain recognizes street scenes

... is very specific, such as a horse as opposed to a cow or a unicorn. At the same time the representation must be sufficiently "invariant" so as to discard meaningless changes in pose, illumination, size, position, and many other variations in appearances. Even a child's brain handles these contradicto...

Vaccine prevents prion disease in mice

They added genetically engineered proteins tagged with red and green fluorescence markers to the bovine aortic endothelial cells, grew them in tissue culture, and filmed them while they passed fluid across the cells’ surface in a simulation of...
