Les céréales et particulièrement le blé dur occupe une place prépondérante dans l’agriculture et par conséquent l’économie Algérienne. Cette importance se justifie à plusieurs niveaux. Cette espèce constitue un élément de base du modèle alimentaire de la population locale. Néanmoins sa production demeure faible pour satisfaire les besoins sans cesse croissants et son importation constitue une lourde facture à l’économie Algérienne. Le travail présenté consiste en l’étude des relations établies entre les aspects physiologiques de la germination et les particularités structurales de la graine du blé dur, sous différents régimes hydriques imposés par des variations des potentiels osmotiques du milieu de germination. Les divergences structurales des graines sont conditionnées par la nature des graines, émanant de huit génotypes, d’origines et comportements différents.

  • 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 flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    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 ...

For many carcinomas and leukaemias in adults, once the disease has reached a certain stage there are no therapies that are able to erradicate the cancer cells and cure patients. There has been progress in the treatment of acute m...
