Link between autism and abnormal blood-vessel function and oxidative stress
... which causes vessels to contract. The endothelium responds to elevated levels of thromboxane by releasing prostacyclin. This event counterbalances the effect on vessels, inducing dilation of the vessel and, in turn, more blood flow. Autism is a complex neurological disorder and oxidative imbalance is one ...More than just pretty faces for this brain region, says Stanford researcher

...lcium channels. Calcium ions flow in and the cell responds by secreting insulin. Mutations, such as Lilly's, that affect the potassium channel, make it less sensitive to the build-up of ATP. The channel remains open, allowing potassium ions to flow in and out rather than accumulate. As a result, insulin s...New drug target might sidestep gleevec resistance, Jefferson scientists show

By looking at how the human brain responds to "fullness" messages sent to the brain by an implanted device that stimulates the stomach, the scientists have identified brain circuits that motivate the desire to overeat in the obese -- the same circuits that cause addicted individuals to crave ...DNA computing targets West Nile Virus, other deadly diseases
