Sobre IBD

ПЦР обнаружение токсигенных генов ’stx 1’ и ’stx 2’ в популяции Escherichia coli, устойчивой к множеству антибиотиков, и фенотипическое выявление ESBL-продуцирующих Escherichia coli, выделенных из традиционных местных сортов домашней птицы, показало, что из 30 собранных образцов 20 были положительными на E.coli. Все 20 изолятов были подвергнуты обнаружению 2 генов токсинов (гены stx1 и stx2) методом ПЦР. Только 3 изолята (L3, L4 и L5) дали продукт ПЦР против специфических праймеров stx1. Все изоляты были отрицательны на наличие гена stx2. Таким образом, 15% популяции E.coli в данном исследовании являются потенциальными изолятами и указывают на то, что здоровые домашние птицы являются носителями патогенных штаммов E.coli. Таким образом, домашняя птица может рассматриваться как основной резервуар E.coli.

  • 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...

    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...
