Sobre IBD

Neste livro, relatámos as propriedades biológicas de cinco espécies de algas marinhas recolhidas na costa de Rameshwaram, Tamil Nadu. Os diferentes extractos (metanol, hexano e acetona) de algas marinhas Sargassum plagiophyllum, S. fusiforme, S. wightii, S. falciparum e Turbinaria ornata foram analisados quanto à sua atividade antibacteriana contra 4 estirpes bacterianas multirresistentes. Entre os diferentes extractos, o extrato de hexano de T. ornata mostrou uma atividade máxima contra Staphylococcus aureus, Klebsiella sp e Pseudomonas aeruginosa. Em seguida, o extrato aquoso de T. ornata foi utilizado para a síntese de nanopartículas de prata. As nanopartículas foram caracterizadas utilizando espetroscopia UV-Vis, FTIR, XRD, potencial Zeta, DLS, FESEM e EDX. A atividade larvicida do extrato de hexano de T. ornata e das nanopartículas de prata de T. ornata foi realizada em duas espécies de larvas de Aedes aegypti e Culex quinquefasciatus e a análise mostrou que existia um efeito larvicida. As AgNPs e o extrato de hexano de T. ornata foram testados quanto às suas propriedades anticancerígenas utilizando a linha celular de cancro do pulmão (A549).

  • 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 ...
