Rayane was a valuable asset to our project for enriching and modernizing security dashboards. She quickly understood our needs and developed clear and effective dashboards on Spotfire, also using tools like Alteryx to automate their management. Her professionalism, responsiveness, and project management skills were particularly appreciated. I recommend her for similar assignments.

    Activité anti-biofilm du cranberry et de l’un de ses métabolites envers Enterococcus faecalis dans un contexte d’infection urinaire. Escherichia coli et Enterococcus faecalis sont deux principaux agents pathogènes impliqués dans les infections du tractus urinaire (ITU) en médecine de ville et à l’hôpital. Ces espèces bactériennes sont responsables d’ITU aigües avec des phénomènes de récurrence et dans des ITU chroniques. La consommation d'antibiotiques est directement corrélée à la résistance des bactéries uropathogènes ce qui montre l'importance de contrôler l'utilisation des antibiotiques et de développer des traitements préventifs et curatifs alternatifs pour les infections urinaires.La consommation alimentaire de cranberry et de leurs extraits est traditionnellement associée avec le maintien en bonne santé des voies urinaires. Par ailleurs, certaines études cliniques semblent montrer un effet préventif des ITU associé à la consommation alimentaire de cranberry. In vitro et ex vivo, la consommation de ces extraits par l’homme réduit l’adhérence de certaines souches d’E. coli aux cellules épithéliales urinaires et la formation de biofilm de différentes espèces. L’hypothèse de travail est que la consommation alimentaire d’extraits de cranberry conduise à la formation de métabolites urinaires qui diminuent l'adhérence des bactéries uropathogènes à l’épithélium urinaire. Ce mécanisme serait à la base de la prévention des ITU par consommation d’extraits de cranberry. Cependant, les métabolites bioactifs restent largement méconnus.
