Texto completo da fonteDouble cardiac and respiratory gating methods help to follow the progression of the disease of transgenic mice's vessel wall using cardiovascular MRI, which is limited by motion artefacts and anatomical small sized structures. Such experiments are affected by the hostile MR environment and require appropriate signal processing and correct QRS detection, but gating software methods are currently limited. We have developed digital real-time gating model which allowed that high-resolution MR images of mouse hearts and aortic arches could acquired using a chain consisting of ECG signal detection, digital signal processing and acquisition window generation. Three signal processing techniques were validated by simulation, then in real time during unique cardiac gating; furthermore a processing/detection method was optimized with respect to ECG signal SNR increasing and R waves detection's precision rates. Finally, the method efficiency was proved using double gating, using pressure transducer or ECG amplitude demodulation, and contrast enhancement of the carotid wall was evaluated. Ln further studiers, the graphical user interface tool that managed the three real time gating strategies will be applied to molecular imaging of atherosclerosis lesions in mice and associated to an large band ECG amplifier in order to clearly define subject's physiopathology state

Texto completo da fonteIn order to determine the authenticity of food materials, several analytical techniques (HPLC, MS, liquid-state NMR) are traditionally employed. These techniques are all the more efficient since the analyzed substances are homogeneous. However, many foods being neither liquid nor solid, it is necessary to carry out some extractions which may deteriorate them. This thesis reports the potential of High Resolution Magic Angle Spinning NMR (HRMAS) for the study of some raw food materials (cheese and meat) allowing for the assignment of the majority of 1H signals as well as the exploitation of the information contained in their 1H HRMAS spectra by multivariate statistical analyses (PCA, DA, PLS-DA) in order to extract from them quality or origin markers. The HRMAS/Chemometrics method enabled the characterization of Parmigiano Reggiano cheese according to its age of ripening, and the Emmental cheese and dried beef meat according to their geographical origin

Texto completo da fonteDeformulation of complex mixtures requires analytical methods for compound identification and quantification. It still represents a real analytical challenge in various industrial fields, such as cosmetics, health, food, materials. In this context, we studied complex mixtures such as detergents and especially, laundry detergents, that represent a constantly growing market. Regulations becoming stricter and consumers requiring more eco-friendly products, manufacturers constantly innove detergent formulations by using bio-based surfactants or enzymes. Laundry detergents containing up to 25 compounds, we focused on the analysis of their major components, i.e. surfactants and enzymes. After developing a comprehensive sample library of such raw materials, 1H NMR and Raman spectrometry were used for surfactant identification and quantification while Isotope Ratio Mass Spectrometry (IRMS) was tested to evaluate their bio-sourced origin. Raman spectrometry combined with chemometric tools such as signal extraction methods was useful for surfactant identification and quantification. Enzymes were identified and quantified using protein precipitation before analyses by LCMS/ MS. All these analytical developments contribute to the establishment of a deformulation strategy for detergent products

Texto completo da fonteThe purpose of this work is to try and set up a new tool for the experimental determination of local magnetic susceptibility tensor. We have worked on an isotructural series of lanthanide oxalate [Ln2(C2O4)3, 9,5H2O] with Ln = La, Ce, Pr, Nd, using NMR of the paramagnetic solid in order to show thefeasability of this kind of studies by solid-state NMR.To determine the local magnetic susceptibility, we propose a semi-empirical approach based on a parameterized point dipole model for local magnetism. The model is based on the knowledge of the crystal structure and the empirical approximation of the point dipole for each paramagnetic center in the structure. The hyperfine dipole interaction is calculated for each NMR observable nucleus by summing the effect of each paramagnetic center on the NMR spectrum within the radius of convergence of our model. The resulting spectrum is then compared to the experimental data and the model parameters are optimized to obtain the best fit.The fact that this semi-empirical model is very fast to calculate opens a wide panel of accessible measurements through this method. For instance, we were able to perform a statistical analysis of each parameter of the local magnetic susceptibility tensor.We have compared our results with SQUID measurements of the macroscopic susceptibility and it showed a good agreement between the isotropic component obtained by both measurements.We explored several possibilities offered by this method in order to access the diamagnetic components of the chemical shift tensor by changing the temperature of our samples. We also tried to push ourstudies towards disordered systems for which diffraction methods have more difficulties to access local magnetic informations

Texto completo da fonteThe aim of this thesis is the development of the NMR by using a chiral liquid crystal as solvent. In a first part, new 2D NMR experiments are described to simplify the proton and carbon-13 spectra. Thus we can easily measure the dipolar couplings and visualize the enantiomeric differentiation. In a second part, we have studied the effect of temperature, magnetic field, polymerisation degree and polymer concentration on the enantiomeric differentiation. We have demonstrated that these various experimental parameters affect differently the enantiomeric differentiation and are important in optimising experimental conditions. Next, we have described an empirical method to determine the absolute configuration using deuterium NMR in natural abundance. Using reference analogous compounds, we have shown that quadrupolar splittings and tridimensionnal geometry of the compounds can be correlated. Then we are able to determine the unknown absolute configuration of a chiral epoxide by studying a series of analogous compounds of known absolute configuration. Finally, the same series of compounds were studied by proton and carbon-13 NMR. By calculating the Saupe order parameters of the rigid part, we have shown that we are able too to determine the absolute configuration giving the same conclusion as previously. We have extended this calculus of order parameters to the entire molecule, and we have shown that the determination of the relative stereochemistry of methylen diastereotopic protons can be done
