Cow protein aids in treatment of gastrointestinal disorder

...n Journal of Gastroenterology, finds that adding a bovine protein called lactoferrin to the existing treatment may yield more effective results, with fewer of the side effects associated with common antibiotic treatment. Lactoferrin has previously been found to be effective at inhibiting the growth of micr...

Synthetic peptide targets latent papilloma virus infections

... layers of tissue. Previous work showed that the bovine papilloma virus hitchhikes by throwing out a thumb - in actuality, a protein called E2 - that latches onto a cellular protein that, in turn, attaches to histone proteins that envelop the chromosome, tethering the plasmid to the chromosomes. The new...

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

...responsible for such brain-destroying disorders as bovine spongiform encephalopathy (BSE) in cattle and vCJD in humans--in the blood of the hamsters in as few as 20 days after the animals had been infected. That discovery occurred about three months before the hamsters began showing clinical symptoms of the...

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

...lar writes. Eating meat from cattle infected with bovine spongiform encephalopathy, or mad cow disease, can cause Creutzfeldt-Jakob disease, a fatal human brain-wasting disorder. More than 160 deaths in Britain were attributed to eating BSE-infected beef, and the disease spread to Europe and Asia before th...

Wisconsin scientists find a way to make human collagen in the lab

...l settings, human collagen would be preferred over bovine collagen because the material now gleaned from cows can prompt an unwanted immune response in patients and it can harbor animal pathogens that might infect humans. The Wisconsin team discovered a way to make the long, slender collagen molecules, in ...

Protein translation in sperm
