Sobre IBD

Xerophytische Arten sind derzeit wegen ihres Reichtums an Sekundärmetaboliten mit interessanten biologischen Aktivitäten begehrt. Ziel dieser Arbeit ist es, den Gehalt an phenolischen Verbindungen zu erforschen und einige biologische Aktivitäten (antioxidative und antimikrobielle) der beiden Xerophyten Asphodelus tenuifolius und Ononis natrix zu untersuchen. Die Hauptergebnisse zeigten einen signifikanten Unterschied im Gehalt an phenolischen Verbindungen und biologischen Aktivitäten in Abhängigkeit von der Polarität des verwendeten Lösungsmittels und der jeweiligen Spezies. So zeichnet sich die apolare Fraktion von Ononis natrix durch ihren Reichtum an phenolischen Verbindungen (Gesamtpolyphenole und Flavonoide) aus, der mit einer hohen antioxidativen Aktivität einhergeht. Andererseits besitzen die apolaren Fraktionen der beiden Arten die besten antimikrobiellen Fähigkeiten. Diese Ergebnisse zeigen, dass die Art und das Lösungsmittel der Extraktion bei der Bestimmung des biologischen Potenzials von Bedeutung sind. Darüber hinaus wertet diese Studie Xerophyten als Quelle für bioaktive Moleküle auf.

  • 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 ...

There has been progress in the treatment of acute m...
