Cocaine Addiction Stems from Desire, Not the Drug
Jeudi 02 Octobre 2008 - 22:00 - 1 mois, 4 semaines depuis - 22 lectures - Presse spécialisée - Scientific American
Scientists know that addictive drugs can mess with the brain’s circuitry and hijack its reward systems, but a July 31 rat study in the journal Neuron shows that psychological factors may be more instrumental in causing these changes than a drug’s chemical effects are. Cocaine use triggers long-lasting cellular memories in the brain, the study found--but only if the user consumes the drug voluntarily.A team led by Billy Chen and Antonello Bonci, both at the University of California, San Francisco, trained three groups of rats to press levers that delivered cocaine, food or sugar. The researchers injected cocaine into a fourth group. When they examined the rats’ brain tissue, they found an increase in synaptic strength within the reward center in those rats that had self-administered sugar, food or cocaine. These cellular memories were short-lived in the sugar and food groups, but in rats that had self-administered cocaine they persisted for up to three months after consumption had stopped. Most interestingly, the brains of rats that had consumed cocaine involuntarily did not show such imprints. [More]

Mercredi 21 Mai 2008 - 06:55 - 6 mois, 2 semaines depuis - 22 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.
