Full textAlpha-radioimmunotherapy can vectorize an alpha particle emitter to target cancer cells. We developed this technique for the treatment of multiple myeloma, with the goal of determining the best suited modalities for later clinical studies. A first step determined the antibody and the radionuclide best suited for radioimmunotherapy and to better understand the mechanisms of alpha-radioimmunotherapy induced cell death. We observed some difference in the radiosensitivity of cell lines and decided in a second step to increase the efficacy of alpha-radioimmunotherapy by combining chemotherapeutic drugs. We found a synergistic effect between alpha-RIT and paclitaxel or doxorubicin. In a third and last step, we analysed the K-ras pathway in order to understand signal transduction following alpha-radioimmunotherapy

Full textCoronary artery disease is the leading cause of mortality throughout the world. Percutaneous coronary interventions are increasingly used as diagnostic and therapeutic tools applied to patient care. The use of X-rays is mandatory to perform these procedures. The side effects of radiation exposure are amongst the risks to which patients undergoing a percutaneous coronary intervention are exposed. In order to minimize these risks, one must identify and optimize factors influencing radiation exposure. Amongst them, the radial vascular access site has been inconsistently associated with an increased exposure, even if it is increasingly adopted worldwide as the primary access site. Other factors have also been identified, yet a clinical classification based on their optimization potential by the physician at patient’s bedside remains to be described. The aims of this thesis were identification of technical factors that could be modified at patient’s bedside and formulation of clinical recommendations influencing patient’s radiation exposure. Four independent and complementary projects have been proposed targeting revascularization strategy, catheters number and type, fluoroscopy acquisition rate and vascular access site as potential factors influencing radiation exposure. All studies were lead at Institut universitaire de cardiologie et de pneumologie de Québec. Fluoroscopy time and dose-area product were used as surrogate indicators of radiation exposure. Our results imply that the revascularization strategy did not influence radiation exposure, but that the use of a multiple catheters approach and a 7.5 images per second low-rate fluoroscopy were associated with a reduction of patient’s radiation exposure. Transradial access was associated with a modest increase in radiation exposure when compared with transfemoral access, but the clinical significance of this small increase is uncertain and unlikely to outweigh the clinical benefits of transradial access. In conclusion, identification of technical factors associated with a reduction in radiation exposure enables the formulation of clinical recommendations aiming at risk minimization for the patient and encourages good radiation protection practices.

Full textThe development of a simple method to obtain perfluoroalkylated building blocks for their subsequent utilization in the synthesis of Rf-containing compounds is therefore essential to organofluorine chemistry. Perfluoroalkylated vinyl metals constitute an important class of these building blocks.In order to prepare a new perfluoroalkylated bulding blocks, we investigated transition metal-catalyzed-free hydrostannylation of ethyl 4,4,4-trifluorobut-2-ynoate 1. The hydrostannylation took place smoothly in the absence of additive, providing regioselectively high yields of the corresponding α or β stannylated alkenoates depending on the nature of the solvent used. Indeed, we have demonstrated that the hydrostannylation of 1 in hexane provided the β-stannylated product with high regioselectivity (>95%) and excellent yield (>97%). Using methanol as solvent, total α-regioselectivity of the hydrostannylation of 1 was observed, providing α -tributylstannylacrylate as the sole regioisomer in a nearly quantitative yield.Theses new vinyltins reagents readily undergo copper (I) catalyst coupling reactions with various electrophiles as allyl, propargyl, benzyl and alkynyl bromides to provide good yields of the new corresponding acrylates esters bearing a β-trifluoromethyl group.This method provided a new efficient entry to this important class of compounds
