Scientists report that anesthesia induces phosphorylation of tau. Tau is a key neuronal protein involved in neurodegeneration in Alzheimer's disease (AD) and several other neurodegenerative disorders. Anesthesia has previously been found to be associated with cognitive impairment and the risk for AD. This study helps elucidate the molecular mechanisms underlying these associations.

Authors: Hooshmand S, Arjmandi BH Osteoporosis is a debilitating disorder that affects both female and male, albeit to a greater extent in women than men. As the demographic shift to a more aged population continues, a growing number of men and women will be afflicted with osteoporosis and a search for potential non-pharmacological alternative therapies for osteoporosis is of prime interest. Aside from existing drug therapies, certain lifestyle and nutritional factors are known to reduce the risk of osteoporosis. Among nutritional factors, recent observations suggest that dried plum, or prunes (Prunus domestica L.) is the most effective fruit in both preventing and reversing bone loss.

SYDNEY, Australia (MedPage Today) -- Diabetes and atrial fibrillation each significantly increase the risk of cardiovascular events, but combined, they increase the five-year risk of death by 61%, researchers reported.

Agriculture has fueled the eruption of human civilization. Efficiently raised, affordable crops and livestock feed our growing population, and hunger has largely been banished from the developed world as a result. Yet there are reasons to believe that we are beginning to lose control of our great agricultural machine. The security of our food supply is at risk in ways more noxious than anyone had feared.The trouble starts with crops. Orange groves in Florida and California are falling to fast-moving blights with no known cure. Cavendish-variety bananas the global standard, each genetically identical to the next will almost certainly be wiped out by emerging infectious disease, just as the Cavendish's predecessor was six decades ago. And as entomologists Diana Cox-Foster and Dennis vanEngelsdorp describe in "Saving the Honey bee," on page 40, a mysterious affliction has ravaged honeybee colonies around the U.S., jeopardizing an agricultural system that is utterly dependent o
