California Mad Cow Case Poses No Threat To Humans
2012-04-25 09:14:40

Lawrence LeBlond for RedOrbit.com The first case of “mad cow” disease in six years has cropped up on a California dairy farm after health and food experts discovered the disease in a dead cow, the US Department of Agriculture (USDA) confirmed on Tuesday. Officials are calling the discovery a stroke of luck because tests are performed on only a small percentage of dead animals that are sent to the transfer facility in Hansford, California. “We randomly pick a number...

Toxic prions in the brain can be detected with self-illuminating polymers. The originators, at Linköping University in Sweden, has now shown that the same molecules can also render the prions harmless, and potentially cure fatal nerve-destroying illnesses. Linköping researchers and their colleagues at the University Hospital in Zürich tested the luminescent conjugated polymers, or LCPs, on tissue sections from the brains of mice that had been...

Prion proteins may be best known for their role in infectious diseases, but not all of them are destructive, new research shows One of the greatest mysterious in cellular biology has been given a new twist thanks to findings reported in Science. Researchers at the RIKEN Brain Science Institute show that prions, proteins that transmit heritable information without DNA or RNA, can contribute to drug resistance and cellular adaptation. Their discovery of a yeast prion with these properties...

Computer modeling supports theory that many dementias spread like prion diseases A new technique for analyzing brain images offers the possibility of using magnetic resonance imaging (MRI) to predict the rate of progression and physical path of many degenerative brain diseases, report scientists at the San Francisco VA Medical Center and the University of California, San Francisco. The technique, developed by SFVAMC scientists in collaboration with a team led by Bruce Miller, MD,...

A University of Alberta research team has discovered that technology commonly used to decontaminate food industry equipment can also rid meat processing plants of lethal microbial material responsible for the human version of the ailment Mad Cow disease. U of A microbiology professors Mike Belosevic and Norm Neumann and engineering professor Mohamed Gamal El-Din demonstrated that infectious proteins found in the brain matter of cattle can be eradicated from water treated with ozone. The...

Prions, the much-maligned proteins most commonly known for causing "mad cow" disease, are commonly used in yeast to produce beneficial traits in the wild. Moreover, such traits can be passed on to subsequent generations and eventually become "hard-wired" into the genome, contributing to evolutionary change. Prions were first found to produce heritable new traits more than a decade ago in laboratory studies of simple baker's yeast. The key discovery then was that some proteins could...

Findings Suggest New View of “Mad Cow” and Other Neurodegenerative Diseases Scientists from the Florida campus of The Scripps Research Institute have identified a single prion protein that causes neuronal death similar to that seen in “mad cow” disease, but is at least 10 times more lethal than larger prion species. This toxic single molecule or “monomer” challenges the prevailing concept that neuronal damage is linked to the toxicity of prion protein...
