ORIGINAL ARTICLE: Brief Report: Effect of Gene Therapy on Visual Function in Leber's Congenital Amaurosis
Mercredi 21 Mai 2008 - 06:55 - 7 mois, 3 semaines depuis - 28 lectures - Presse spécialisée - New England Journal of Medicin A form of Leber's congenital amaurosis is caused by mutant RPE65, a critical component of the visual cycle. Two early clinical trials to assess subretinal injection of a viral vector containing RPE65 in young adults with advanced retinal degeneration show that this approach is generally safe in the short term, although one group reported an adverse event: macular hole. The authors observed improvement in some measures of visual function. |

Extreme Tech: Scientists Set Sights on an Implantable Prosthetic for the Blind
Mercredi 19 Mars 2008 - 11:15 - 9 mois, 3 semaines depuis - 28 lectures - Presse spécialisée - Scientific American The ability to see requires healthy eyes, but it also requires that signals can get from the eyes to the parts of the brain involved in vision. A Boston neuroscientist hopes to deliver a ray of hope to the blind by bypassing eyes and optic nerves damaged by illness or head trauma and sending image information directly to the regions of the brain that process them. |

Scientific American Magazine: At the Edge of Life's Code
Dimanche 16 Mars 2008 - 22:00 - 9 mois, 3 semaines depuis - 28 lectures - Presse spécialisée - Scientific American On an airport shuttle bus to the Kavli Institute for Theoretical Physics in Santa Barbara, Calif., Chris Wiggins took a colleague’s advice and opened a Microsoft Excel spreadsheet. It had nothing to do with the talk on biopolymer physics he was invited to give. Rather the columns and rows of numbers that stared back at him referred to the genetic activity of budding yeast. Specifically, the numbers represented the amount of messenger RNA (mRNA) expressed by all 6,200 genes of the yeast over the course of its reproductive cycle. “It was the first time I ever saw anything like this,” Wiggins recalls of that spring day in 2002. “How do you begin to make sense of all these data?” |
