The study was published online in the June 29 issue of the Journal of Neuroscience, which is the official journal of the Society for Neuroscience. The brain has specific receptors, called GABA-type receptors, that serve modulate the rapid communication between cells in the brain. GABA receptors in the brain act as an inhibitory “brake” on excitatory neurons in the brain. The OHSU researchers found that these GABA-type receptors in the retinal cells stopped functioning properly when vitamin C was removed. Because retinal cells are a kind of very accessible brain cell, it’s likely that GABA receptors elsewhere in the brain also require vitamin C to function properly, von Gersdorff said. And because vitamin C is a major natural antioxidant, it may be that it essentially...

Originally FDA-approved in 1999 beneficial to the surgical usage of soothing myopia (-1.0 to -3.0 diopters), Intacs are two dwarfish, free lunated pieces of a pliable polymer that are inserted into the cornea to reshape the impudence exterior of the estimate. The FDA in July 2004 granted Intacs a Humanitarian Emblazoned bearing Immunity in favor of appliance in the method of treating of keratoconus largely as of Intacs’ close custody memorial and for solitary a not many handling options, of that kind viewed like corneal transplants, were to be turned to account instead of keratoconus. The approval allows Intacs to have existence marketed on this account that resolution or exclusion of myopia and astigmatism in keratoconus patients at which place functional chimera is none longer...
