Full textNMR spectroscopy is a unique modality to evaluate intracellular environment in vivo. Indeed observed molecules are specifically intracellular and generally have a biochemistry role and a specific cellular compartmentation. That could be a useful tool to understand cell functioning in their environment. My thesis work consisted in development of new sequence in both diffusion and phosphorus NMR spectroscopy.My first study was to develop a diffusion-weighted spectroscopy at ultra-short diffusion time to look at the anomalous diffusion in the rat brain. ADC evolution as a function of time shows that brain metabolites motion is mainly due to random diffusion and that active transport (if exist) are negligible. Data modeling evidences that diffusion at short diffusion time is sensitive to cytoplasm viscosity and short scale crowding. In collaboration with the pharmaceutical company, this technique was chosen to follow up transgenic mice (rTg4510), model of tau pathology. Preliminary results show significant differences of ADC at an early stage of neurodegenerescence (3 and 6 months).Phosphorus spectroscopy allows observation of metabolites directly implicated in energetic processes. During this thesis, localization sequences were developed to measure intracellular pH in the primate striatum. These sequences are supposed to be used to evaluate the potential of pH as a biomarker of neurodegenerescence in a phenotypic model of the Huntington disease in the non-human primate

Full textThe first part of this work concerns the study of the metabolic compartmentation of glutamate and glutamine in the isolated and perfused rat liver. The results are obtained by using 13C enriched substrates, coupled with nuclear magnetic resonance detection. Thus, we have shown the existence of two glutamate pools, one in the periportal zone and the second in the perivenous zone. The quantification of these pools can be peformed by 13C specific enrichments determination. In the same way, biochemical assays on cellular extracts and excreted perfusate have specified the role of glutamate, glutamine and urea in the ammonium ions detoxification phenomenon in the liver. The second part of this work contributes to technological and methodological developments in the clinical use of magnetic resonance spectroscopy (MRS). Large radiofrequency coils have been elaborated to observe different nuclei : a 31P/IH coil (2T). In the same way, 2 dimension spectroscopic imaging sequences have been developed. Perfectly, localized 31P MRS spectra were performed. The comparison of investigation results on healthy volunteers and patients with various pathologies have shown significant differences. 13C MRS spectra with proton decoupling, were performed on volunteers (aftter power deposition and tissu heating calculation). 13C human liver spectra were performed at 2T for the first time by using spectroscopic imaging sequence

Full textNemaline myopathy (NM) is the most common of the non-dystrophic congenital myopathies and is characterized by muscle weakness and accumulation of an electron dense material (rods) within the sarcomeric units. Over the past decade, the generation of mouse models of NM allowed to identify in vitro several physiopathological mechanisms involved, at least in part, in muscle weakness in NM. This project has been devoted to the in vivo phenotypic characterization of the skeletal muscle function of mouse models mimicking mild and severe human forms of NM. Skeletal muscle function was assessed on four mouse models of NM with an original and strictly noninvasive experimental setup designed and built in our laboratory allowing 31P-magnetic resonance spectroscopy (31P-MRS) and multimodal magnetic resonance imaging (MRI) investigations, including Dixon, T2 mapping and Diffusion Tensor Imaging (DTI). Our results suggest that in vitro alterations did not necessarily translate into similar changes in vivo. 31P-MRS illustrated an altered energy metabolism only for the mouse models mimicking severe form of NM. Our Dixon MRI investigations showed that fatty infiltration was negligible. Finally, T2 maps and DTI experiments provided relevant noninvasive and quantitative biomarkers for monitoring the severity and/or the progression of NM in patients
