Discovery Promises Simpler Therapy for Sickle Cell Disease

...ough the release of nitric oxide is a major factor behind the disease's primary symptoms -- including oxygen deprivation and blocked vessels that can lead to pain, clots and stroke. Thus, therapies that restore nitric oxide to blood cells might serve as a useful method for treating the disease, said HHMI re...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 A...
