Più di quasi ogni altro campo della biologia, la filogenesi, che descrive le relazioni tra le diverse specie, è soggetta a continue revisioni e riorganizzazioni. I vecchi paradigmi filogenetici vengono ristrutturati poiché i ricercatori traggono sempre più spesso le loro conclusioni sul grado di parentela da dati molecolari come il DNA. In particolare, le sequenze di DNA che mostrano un grado costante di variazione all’interno di un taxon e tra taxa diversi si sono dimostrate utili per le ricostruzioni filogenetiche. Tali marcatori filogenetici possono essere utilizzati per distinguere specie diverse. Spesso questo approccio è ragionevole e già consolidato in molte entità filogenetiche, ad esempio nel caso dei batteri. Anche la ricostruzione degli alberi genealogici delle piante si basa sempre più sui marcatori filogenetici. Tra questi marcatori, la cosiddetta regione ITS riveste un ruolo fondamentale. In questo lavoro si indaga se sia possibile e ragionevole classificare le specie vegetali basandosi esclusivamente sulle differenze nelle loro sequenze ITS.

  • 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...
  • Advances in Flavivirus Research
    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...

  • Brain Asymmetry of Structure and/or Function
    Lesley J. Rogers / Lesley JRogers
    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 an observed decrease in the global mortality from cancer, mostly atributable to improved, particularly early, detection and prevention. 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...
