Brown team finds crucial protein role in deadly prion spread

...bstantially 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 w...

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

...is the 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," ...

Blood transfusion-transmitted infections: A global perspective

...eldt-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 ...

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

...ow many 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 org...

History of human cannibalism eats away at researchers

... to cause fatal neurodegenerative diseases such as mad cow disease. These diseases are cumulatively known as transmissible spongiform encephalopathies (TSEs) and in humans, include CJD (Creutzfeldt-Jakob disease) and kuru. Kuru is confined to a human population in Papua-New Guinea and is transmitted ...

New test to detect rare proteins in blood

...mportant molecules, such as the prion protein (for mad cow disease with Mansun Sy at Case Western University) and TNF-alpha (for autoimmune diseases), and will be developing tests for other cancer markers including lung cancer and colon cancer. All proteins tested so far with FACTT have been detected wit...

Prions rapidly 'remodel' good protein into bad, Brown study shows

...s proteins that cause fatal brain ailments such as mad cow disease and scrapie in animals and, in rare cases, Creutzfeldt-Jacob disease and kuru in humans. Because similar protein self-replication occurs in neurodegenerative diseases, the findings, published in the latest issue of Nature, may also help ...

Variant prion protein causes infection but no symptoms

...eases such as Creutzfeldt-Jacob disease in people, mad cow disease in cattle and chronic wasting disease in deer and elk. Now, new research suggests that a variant form of abnormal prion protein--one lacking an "anchor" into the cell membrane--may be unable to signal cells to start the lethal disease pro...
