Implantable device cuts obstructive sleep apnea symptoms

Posted: 10 Jun 2016 02:36 PM PDT

Since the 1980s, continuous positive airway pressure (CPAP) -- in which positive pressure is pushed through the nasal airways to help users breathe while sleeping - has been by far the most widely used treatment for obstructive sleep apnea (OSA). With more than 18 million people experiencing OSA, a number expected to rise, new results from a case study of a new device implanted in the chest called hypoglossal nerve stimulation (HGNS) offers promise for patients with moderate to severe OSA who cannot tolerate CPAP.

Alzheimer's researchers find clues to toxic forms of amyloid beta

Posted: 10 Jun 2016 02:36 PM PDT

Much of the research on Alzheimer's disease has focused on the amyloid beta protein, which clumps together into sticky fibrils that form deposits in the brains of people with the disease. In recent years, attention has turned away from the fibrils themselves to an intermediate stage in the aggregation of amyloid beta. A new study helps lift the veil on the structure and behavior of these neurotoxic 'oligomers.'

Discovery of molecular protection linked to a degenerative neuromuscular disease

Posted: 10 Jun 2016 08:27 AM PDT

Kennedy's disease leads to progressive muscle wastage. It is a condition that affects only men and it appears between 40 and 50 years of age. There is no specific treatment available. In individuals with this disease, muscle cells and motor neurons die over the years because they accumulate a protein that is mutated. Researchers discover that this protein has a self-protective mechanism through which the deleterious effects of the mutation are delayed.
