The eyes may or may not be windows to the soul, as the old adage goes, but scientists are reporting evidence that a peek into the eyes of cattle may become the basis for a long-sought test to detect infection with the agent that causes Mad Cow Disease. That test could help prevent the disease from spreading in the food supply. A study on using the tell-tale glow given off by eyes infected with the Mad Cow agent appears in ACS' semi-monthly journal Analytical Chemistry. Jacob Petrich and...

Important changes made to Pennsylvania's parts ban HARRISBURG, Pa., Aug. 31 /PRNewswire-USNewswire/ -- With thousands of Pennsylvania hunters heading off to hunt big game in other states and Canadian provinces, Pennsylvania Game Commission Executive Director Carl G. Roe reminds hunters that, in an effort to prevent the introduction of Chronic Wasting Disease (CWD) into the Commonwealth, the agency prohibits hunters from importing specific carcass parts from members of the deer family -...

Variably protease-sensitive prionopathy shares genotype characteristics with Creutzfeldt-Jakob disease A new sporadic prion protein disease has been discovered. Variably protease-sensitive prionopathy (VPSPr), as it has been named, is the second type of complete sporadic disease to be identified since Creutzfeldt-Jakob disease (CJD) was reported in the 1920s. The landmark finding from the National Prion Disease Pathology Surveillance Center at Case Western Reserve University is published in...

Metal surfaces spur conversion of normal prion protein into disease-causing prions In a startling new study that involved research on both sides of the Atlantic, scientists from The Scripps Research Institute in Florida and the University College London (UCL) Institute of Neurology in England have shown for the first time that abnormal prions, bits of infectious protein devoid of DNA or RNA that can cause fatal neurodegenerative disease, can suddenly erupt from healthy brain tissue. The...

"Based on the monitoring records of spongiform encephalopathy in two Nordic countries, we studied the possibility of transmission of the sporadic form of CJD through general surgery", explains Jesús de Pedro, main author of the study and head of prion monitoring in patients at the National Epidemiology Centre of the Carlos III Health Institute. The finding, published recently in the Journal of Neurology, Neurosurgery & Psychiatry, reveals that, with a few exceptions,...

Prion diseases are lethal neurodegenerative disorders that include Creutzfeldt-Jakob disease (CJD) in humans and bovine spongiform encephalopathy (BSE; commonly known as mad cow disease) in cows. A team of researchers, led by Adriano Aguzzi and Christina Sigurdson, at UniversitätsSpital Zrich, Switzerland, has generated data in mice that provides greater understanding of the factors that determine how easy it is for prion diseases to be transmitted to a new host species. This information...

Study in mice may offer clues for treating Alzheimer's disease National Institutes of Health (NIH) scientists investigating how prion diseases destroy the brain have observed a new form of the disease in mice that does not cause the sponge-like brain deterioration typically seen in prion diseases. Instead, it resembles a form of human Alzheimer's disease, cerebral amyloid angiopathy, that damages brain arteries. The study results, reported by NIH scientists at the National Institute of...

Prions are a special class of proteins best known as the source for mad cow and other neurodegenerative diseases. Despite this negative reputation, according to a new report in the February 5th issue of the journal Cell, a Cell Press publication, a prion may also have important and very positive roles in brain function. The researchers suggest that a prion-like protein may participate in memory in higher eukaryotes, from sea slugs on up. "The persistence of memory is a fundamental problem,"...
