In the rat visual system, the uncrossed retinotectal projection undergoes a topographical refinement within the first two postnatal weeks. We have studied the role of nitric oxide (NO), a retrograde messenger which couples pre- and postsynaptic activation, in the development of the uncrossed retinotectal projection and in the plasticity of this pathway as a(More)
Myofiber degeneration, inflammation, and fibrosis are remarkable features of Duchenne muscular dystrophy. We hypothesized that the administration of imatinib mesylate, an inhibitor of tyrosine kinase and TGF-beta pro-fibrogenic activity, could improve the muscular conditions in mdx mice. Four-week old mdx mice were treated and exercised for 6 weeks.(More)
The genotoxic effect of the Austroplenckia populnea chloroform fraction from barkwood extract was tested in vivo on peripheral blood cells of Swiss mice with the comet assay (SCGE), and the clastogenic effect was investigated on peripheral blood cells of Swiss mice and bone marrow cells of Wistar rats, with the micronucleus and chromosome aberrations tests.(More)
