Sobre IBD

Este estudo avaliou as propriedades físico-químicas das polpas de 28 variedades de tâmaras colhidas no estádio Tmar em três oásis do Adrar mauritano (épocas 2010-2011), utilizando 13 parâmetros. As análises estatísticas revelaram uma variabilidade significativa entre as cultivares, independentemente da sua origem geográfica, reflectindo uma grande diversidade físico-química. Os parâmetros mais discriminantes foram o teor de água, os açúcares, as cinzas, o cálcio e o magnésio. Além disso, foram comparados os compostos fenólicos, os flavonóides e a atividade antioxidante de seis variedades nos estádios Blah e Tmar. O teor em polifenóis e flavonóides e a atividade antioxidante foram mais elevados no estádio Blah, com uma forte correlação positiva entre os polifenóis totais e a atividade antioxidante. Finalmente, o controlo da maturação mostrou uma diminuição progressiva dos compostos fenólicos e dos taninos solúveis, com valores máximos observados nas variedades Amsakhsi, Tiguidert e Bezoul.

  • 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...

    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 ...
