Mad Cow disease and its human variant Creutzfeldt"”Jakob disease, which are incurable and fatal, have been on a welcome hiatus from the news for years, but because mammals remain as vulnerable as ever to infectious diseases caused by enigmatic proteins called prions, scientists have taken no respite of their own. In the Oct. 29 edition of the journal Science, researchers at Brown University report a key new insight into how prion proteins "” the infectious agents "” become...

The eyes of sheep infected with scrapie "“ a neurological disorder similar to mad cow disease "“ return an intense, almost-white glow when they're hit with blue excitation light, according to a research project led by Iowa State University's Jacob Petrich. The findings suggest technologies and techniques can be developed to quickly and noninvasively test for transmissible spongiform encephalopathies, progressive and fatal neurological diseases such as mad cow disease in cattle and...

A cow's eyes may show signs of neurological disorders such as mad cow disease, according to scientists.Noticing the signs early enough may help prevent infected meat from reaching the food supply.Researchers at the Iowa State University examined the retinas of sheep infected with scrapie -- a disease similar to mad cow disease. The researchers stated in the journal Analytical Chemistry that the sick sheep's eyes had a unique "glow."People who eat contaminated meat may contract a brain-wasting...

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...
