Accuracy of movements requires that the central nervous system computes approximate inverse functions of the mechanical functions of limb articulations. In vertebrates, this is known to be achieved within the cerebellar pathways, and also in the cerebral cortex of primates. A cybernetic circuit achieving this computation allows accurate simulation of fast… (More)
We investigated whether Merkel cell carcinoma (MCC) patients in France carry Merkel cell polyomavirus (MCPyV) and then identified strain variations. All frozen MCC specimens and 45% of formalin-fixed and paraffin-embedded specimens, but none of the non-MCC neuroendocrine carcinomas specimens, had MCPyV. Strains from France and the United States were similar.

Facial port-wine stains are capillary malformations, which can reveal, very rarely, Sturge-Weber syndrome (SWS). SWS is a severe neurocutaneous syndrome, which involves a facial port-wine stain reaching the first branch of trigeminal nerve (V1), ophthalmologic abnormalities (especially congenital glaucoma) and neurologic signs (seizure, mental retardation,… (More)
INTRODUCTION In 2008 the national ranking examination (NRE) will include a test on critical reading of scientific articles. This decision has provoked controversy about whether reproducible correction is possible. The aim of our study was to assess the consistency of grading between this two-part test (critical analysis and summarizing, analyzed… (More)
