Повний текст джерелаParkinson's disease is a neurodegenerative disorder characterized by motor troubles such as akinesia, rigidity and tremor. The loss of dopaminergic neurons from the nigro-striatal pathway will lead to biochemical changes in the putamen. Especially, works on electrophysiology, micro dialysis and magnetic resonance spectroscopy (MRS) suggests hyperactivity of the glutamatergic cortico-striatal pathway associated with glial microenvironment changes. These observations suggest a modification of the glutamate-glutamine cycle occurring between neurons and astrocytes in response to neuronal loss.In this thesis, two approaches have been developed in order to follow by MRS the metabolic changes occuring in Parkinson's disease. In particular, we want to follow the changes in glutamate-glutamine cycle inside the putamen.in a first study, a a 1H MRS approach was used to assess the metabolic changes inside the putamen of Parkinson's disease without or under dopaminergic treatment. In this study, changes in N-acetylaspartate, creatine and myo-inositol were observed in Parkinsonian patients, but no change in glutamatergic metabolism was observed. This could be due to the lack of sensitivity of the technique to differentiate glutamate and glutamine pools.Thus, we chose to use a new 13C carbon MRS approach in order to follow dynamically in vivo the glutamate-glutamine cycle inside the brain: dynamic nuclear polarization (DNP). Thanks to the high sensitivity of this technique, it is now possible to follow metabolic pathways in vivo in real time. The implementation of DNP was assessed under a control group of animals. This technique offers a new promising tool for the analysis of this flow under pathologic conditions.To conclude, the MRS strategies for clinical diagnostic strategies remain, at present, poorly sensitive for the study of glutamate-glutamine cycle in vivo in humans. The development of DNP opens the door to a new approach for real-time monitoring of this cerebral metabolism Even if DNP is mainly used in preclinical studies at present, the development of new clinical systems could lead to its emergence as a new diagnostic strategy in clinical imaging

The need to come up with new and novel antibiotics that utilize unique mechanisms, to which bacteria cannot generate resistance, was the main motivation of this study. Tyrocidine peptides are non-selective antibiotics that have such properties. However, very limited information is available about their mechanism of action. The aim of this study was to determine the mechanism of action of tyrocidine peptides, tyrocidine A, tyrocidine B and tyrocidine C.

Повний текст джерелаThe present doctoral thesis is focused on the study of resolution-enhanced techniques for Nuclear Magnetic Resonance (NMR) spectroscopy in order to achieve a simpler and more precise structural elucidation of small molecules. The work has been presented as a compendium of seven publications written in several prestigious scientific journals. The publications develop in depth the application of resolution improvements for i) a precise and efficient measurement of homo- and heteronuclear coupling constants and ii) an optimization of anisotropic parameter measurements through weakly aligned means. These two topics are developed by: 1. The practical implementation of modern NMR techniques to improve the digital and signal resolution of 2D experiments without compromising the experimental time. 2. The design of improved pulse sequences to achieve the measurement of longer- range heteronuclear connectivities. 3. Implementation of novel NMR approaches to study samples in anisotropic environments, as well as the design of new pulse sequences adapted to the experimental measurement of NMR parameters in these media. 4. Evaluation of new NMR strategies for efficient structure discrimination using anisotropic NMR parameters. 5. Application of protocols for the easy automatization and measurement of coupling constants in isotropic and anisotropic media.

Повний текст джерелаFood packaging plays a great role in the food industry to maintain food products quality as long as possible. Polymer films are widely used in food packaging and also attract attention because of their outstanding advantages. Since petroleum-based polymers are known to cause environmental concerns, biodegradable polymers like PLA were studied more intensively in recent years due to their environmentally friendly properties. The application of reinforced films exceeds simple ones in achieving specific functions and enhancing their properties such as barrier properties. Since the films structures are more complex, quality control is more challenging. In industry, off-line methods are vastly used for quality control of the produced films while variability in raw materials and processing conditions substantially change the film specifications. Consequently, real-time inspection and monitoring of polymer films is needed on the production line to achieve a real-time quality control of the films. A fast and non-invasive near-infrared (NIR) imaging system is proposed to characterize biodegradable polylactic acid (PLA) films containing talc, and produced by extrusion film-blowing for packaging applications. The ultimate goal is to use the system for quality control on the extrusion line, and after a post-processing via thermal treatment (annealing). A set of PLA-talc films with varying talc contents were produced and submitted to annealing under different conditions. NIR images of the films were collected after which the samples were characterized for their physical, mechanical, and gas barrier properties. Multivariate imaging techniques were then applied to the hyperspectral images. It is shown that various talc loadings can be distinguished, and the information contained in the NIR spectra allows predicting the film properties. In all cases, the proposed approach was able to track the variation in film properties with good accuracy

Повний текст джерелаThis work deals with the synthesis, shaping and characterization of RE1-xMxF3-x (RE = La, Sm, Ce et M = Ba, Ca, Sr) tysonite-type solid solutions. In a first part, onemeticulous approach has been set up for La1-xBaxF3-x solid solution, chosen as a reference.The solid-state synthesis of these materials led to a better knowledge of their chemicalcomposition (Vegard’s laws) and of the structure-ionic mobility correlations. The impact ofthe sintering process on the ionic conductivity is also highlighted. In a second part, the effectsof the nanostructuration conducted by ball-milling of the microcrystalline samples areevaluated. The use of the Design of Experiments methodology led to identify the optimummilling conditions. It appears that the synthesis of electrolytes can be sped- and scaled-up,while keeping high ionic conductivity properties. At last, this approach is applied on othertysonite-type solid solutions, to look for the best electrolyte. The Ce/Sr and Sm/Casubstitutions generate very promising ionic conductors but not really (electro)chemicallystable compounds. A compromise has been found with the choice of the La1-xSrxF3-x solidsolution as the FIB electrolyte for the electrochemical performances tests, regarding its higherchemical stability

We have measured the values of nitrogen-14 quadrupole coupling constants (QCC), employing NMR relaxation techniques, for a designed series of para-substituted benzonitrile derivatives. It is found that for substituents bearing lone-paired electrons result in lower magnitudes of QCCs(14N) than the parent compound, benzonitrile. This observation provides solid evidence in support of the existence of “negative hyperconjugation” (NHC). For the methyl-substituted benzonitrile, the same observation is also present and can be rationalized by the well-known hyperconjugation effect. Although both effects may be viewed as the no-bond double-bond resonance based on valence bond theory, only NHC can be well demonstrated by “orbital interaction,” reported by Schleyer, within the molecular orbital theory. In cyanohalogens, the trend of QCCs(14N) cannot be accounted for in terms of the inductive effect reported for BrCN. On the other hand, it can be well understood on the NHC basis. Moreover, this trend of QCCs indicates that the -effect is shielded by the carbon atom and thus only pi-effect is the dominant factor affecting variations of QCC(14N) values. This is in accord with the “shielding effect” proposed much earlier in literature. More significantly, the NHC argument can be applied to account for the chain-conjugated structure proposed for sydnone compounds in the manner that the lone-paired electrons on the exocyclic oxygen, based on the Kartritzky hybrid structure, proceeds NHC into the pi-system of the N(2)-N(3)-C(4)-C(5) framework. Combined with the “ionic covalent bond” utilized for interpretation of the substantial stabilization of fluoro-substituted methanes, we conclude that the Kartritzky structure may also explain the IR and X-ray data observed for the highly polar C(5)-O(6) bond. It is then reasonable to exclude the aromaticity of the sydnone ring, whereas the semi-aromatic resonance structure is still favored from the viewpoint of NHC.
