Parmi les nombreuses espèces de la flore brésilienne possédant des propriétés biologiques intéressantes, on trouve l’Ilex paraguariensis A. St.-Hil. (Aquifoliaceae), communément appelé yerba mate. Les propriétés émétiques, astringentes, médicinales et bactéricides sont des indications populaires attribuées à cette espèce. Dans cette optique, l’objectif de cet ouvrage était d’évaluer l’activité antibactérienne et antifongique des extraits de feuilles et de rameaux. Le matériel végétal utilisé pour produire les extraits a été collecté à Santo Ângelo/RS, les feuilles et les branches ont été séparées, lavées, macérées, broyées avec de l’éthanol à 70 %, puis filtrées et évaporées. L’activité antimicrobienne a été évaluée à l’aide de la technique de diffusion sur milieu solide. La concentration de 100mg/mL a montré le meilleur effet inhibiteur contre tous les micro-organismes testés. Les résultats obtenus ont prouvé l’activité antifongique marquée des extraits d’I. paraguariensis, lorsqu’ils sont comparés aux résultats d’inhibition de l’antifongique commercial Fox®, utilisé comme étalon comparatif. Les résultats positifs indiquent que cette plante est une alternative pour contrôler les micro-organismes dans le stockage des semences.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...

    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...
