I first addressed the issue of the role of intracellular calcium signal in various models.With the patch-clamp technique, we characterized the electrophysiological and pharmacological properties of three voltage activated calcium channels in rat aortic myocytes in culture and studied their beta adrenergic regulation. We showed a differential expression as a function of cellular phenotype. Then we addressed the issue of the role of the intracellular Ca2+ signal in long-term potentiation (LTP) and long-term depression (LTD) and showed that similar intracellular Ca2+ elevation in CA1 pyramidal neuron induced long-lasting potentiation and long-lasting depression that share common mechanisms with LTP and LTD.
I turned then to the methodology and biostatistics used in clinical research and epidemiology. I contributed to study designs, protocol writing, and data analyses in various clinical areas. This involvement motivated statistical developments. A study which aimed at measuring intra and inter-observer agreement motivated the development of a new statistics, dzeta, that measures agreement for ordered ratings with 3 categories. I also computed the corrections to the asymptotic distribution of such statistics based on multinomial distribution. I also used a Markov model in a medico-economic study that aimed at evaluating the cost-efficacy of the surgery of epilepsy.
Now I contribute to studies related to HIV: an international clinical trial aiming at comparing two antiretroviral drugs in the prevention of mother to child transmission of HIV through breastfeeding; an observational study aiming at determining whether co-infection HIV - tuberculosis favours emergence of Mycobacterium Tuberculosis strains. I also address the issue of stress in students. I have coordinated a cross-sectional study in order to determine whether the academic program predicts a high level of perceived stress, irrespective of personal and environmental factors, and coping strategies.
