La contaminazione da arsenico delle acque sotterranee è molto diffusa e ci sono diverse regioni in cui la contaminazione da arsenico dell’acqua potabile è significativa. Migliaia di persone sono già state identificate come affette da avvelenamento da arsenico, oltre ai milioni di persone potenzialmente minacciate dal consumo di acqua contaminata. È urgente fornire acqua priva di arsenico per proteggere immediatamente la salute e il benessere delle persone che vivono nelle aree colpite dall’arsenico. Nella maggior parte delle situazioni, la sostituzione dell’acqua del pozzo con una fonte alternativa sicura e affidabile non è un compito facile. I sintomi e i segni causati da un’elevata esposizione a lungo termine all’arsenico inorganico differiscono tra individui, gruppi di popolazione e aree geografiche. Pertanto, non esiste una definizione universale di malattia causata dall’arsenico. Ciò complica la valutazione dell’onere dell’arsenico sulla salute. È stato dimostrato che microrganismi come Thiobacillus ferrooxidans, Lepto spirillum ferrooxdans e funghi come Scopulariopsis previcaulus, Penicillum sp., Gliocladium roseum e il lievito Candida humicola ossidano l’As (III) nella forma meno tossica As (V).

  • 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...

    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 ...
