L’objectif de cette communication est l’étude de deux micro-écoulements différents au moyen d’un système de micro-PIV non inversé. Ces écoulements diffèrent entre eux par les aspects suivants: Le premier, un écoulement pulmonaire, est représentatif d’un flux stationnaire confiné. Le second, la formation de gouttelettes par un capillaire contrôlé par un cristal piézoélectrique, est représentatif d’un écoulement périodique à surface libre. La faisabilité de ce type de mesure est évaluée en mettant l’accent sur le fait que ces expérimentations ont été menées sur des micro-écoulements courbes tridimensionnels. [less ▲]

This research work is dedicated to develop and bring to light the contribution of nuclear magnetic resonance (NMR) in the study of the actinide ions and their complexes in aqueous or in organic solvents. We use several advanced NMR techniques. The dispersion of the longitudinal relaxation time T1 of solvent nuclei with the magnetic field (NMRD) yields information on the magnetic properties of paramagnetic actinide ions. The sensitivity of NMR to the exact nature of the ground state of actinide ions is also illustrated by detailed studies on the complexes of U, Np, Pu, Am and Cm in different oxidation states. It will be shown that the paramagnetic shifts induced by the actinide ions originate from both a through space dipolar contribution and a through bonds contact contribution. The latter gives access to delocalized unpaired electron densities that are directly related to the covalency of the actinide-ligand bonds. However, electronic densities can only be obtained after separation of the two contributions. This separation made thanks three different methods based on studies with variable temperature and by synthesizing highly symmetric and anisotropic complexes. The use of dipolar contribution can be, as for her, related to the geometry of complexes formed in solution. This method of determination of solution structure is illustrated in the case of four specially designed N-polyaromatic ligands actinide/lanthanide partitioning by liquid-liquid extraction, an essential step for the ultimate nuclear fuel reprocessing. Besides their structure determination, the use of NMR techniques allowed of determined the stoechiometry and speciation in solution of these complexes. [less ▲]

In the last decade, a new electrophysiological tool has become available since the development of painless magnetic stimulators able to activate the primary motor cortex and the motor roots in conscious man. Therefore, it became possible to measure the conduction time within fast-conducting central motor pathways by substracting from the total latency of muscle responses elicited by cortical stimuli the conduction time in peripheral nerves. This technique proved sensitive enough to illustrate early abnormalities of central motor conduction in various neurological diseases such as multiple sclerosis, amyotrophic lateral sclerosis, cervical spondylotic myelopathy, degenerative ataxias or hereditary spastic paraplegias. When recorded early after stroke, motor evoked potentials are also a valuable tool to predict functional outcome. They can also illustrate subtle pathophysiological disturbances in diseases where there is no direct involvement of central motor pathways such as Parkinson's disease, dystonia or epilepsy. Magnetic cortical stimulation also offers unique opportunities to explore intracerebral inhibitory and excitatory circuits and mechanisms of brain plasticity. The recent development of rapid rate stimulators also enables functional studies of non-motor cerebral regions such as visual or frontal cortices. Moreover, rapid rate stimulation seems useful in the treatment of drug-resistant depression but the safety of this procedure, particularly with regard to the production of seizures or kindling, remains to be fully documented.

PositIon emission tomography using 18-fluorodeoxyglucose (FDG-PET) is an imaging technique based on metabolic criteria rather than morphological criteria. We discuss the contribution of this technique in the field of pulmonary oncology and we summarize our work which has demonstrated the performance capacity of PET: to discriminate the malignant nature of a solitary pulmonary nodule; to improve sensitivity over CT for mediastinal assessment in non-small cell lung cancer; to seRach for distant metastasis in patients with non-small cell lung cancer; to complement CT imaging to better dissociate tumor residue or recurrence from post-therapeutic sequelae in non-small cell lung cancer. Finally, we present different expected progress for the future. [less ▲]
