Apomorphine, a dopamine receptor agonist (given in a dose of 0.75 mg s.c.), was administered to 8 healthy volunteers; electroencephalograph (EEG) and event-related potential (ERP) mapping were performed before dosing and 0.5, 1.5 and 2.5 h after dosing. Apomorphine caused an overall increase in beta activity at time 0.5 h in both absolute and relative(More)
Pregnant rats were treated orally with aluminum lactate (400 mg Al/kg/day) during three periods of gestation to determine the treatment's influence on mortality, weight gain, neuromotor maturation, and learning abilities of their pups. No effect of treatment on litter size, mortality rate, and weight gain of pups was detected. In the negative geotaxis test,(More)
INTRODUCTION The central nervous system involvement has been reported in 20% of cases of primary Sjogrën's syndrome (SS), a chronic autoimmune disease characterized by a disorder of the exocrine glands secondary to progressive lymphocyte infiltration. Classically described neurological manifestations include sensorimotor deficits, aseptic meningitis or(More)
Previous studies have demonstrated that the nocturnal oscillations of plasma renin activity (PRA) exactly reflect rapid eye movement (REM) non-REM (NREM) sleep alternation with levels of PRA that increase during NREM sleep and decrease during REM sleep. These studies were based exclusively on conventional scoring of sleep stages. In the present study, we(More)
Plantar fracture-dislocation of the tarso-metatarsal joint (Lisfranc plantar fracture-dislocation) is rather unusual. The authors described a case sustained in a 39 years old man injured in a motorcycle road traffic accident. Mechanism was recognized as plantar hyperflexion combined with an axial foot compression. Open reduction, and K-wires fixation were(More)
Palladium and ruthenium nanoparticles have been prepared following the organometallic precursor decomposition methodology, under dihydrogen pressure and in the presence of borane protected P-stereogenic phosphines. NMR (Nuclear Magnetic Resonance) monitoring of the corresponding syntheses has permitted to determine the optimal metal/ligand ratio for leading(More)
