Diese Studie umfasste fünf Antigene, die jeweils mit drei Immunglobulinen (Gesamt-IgG, IgG1 und IgG4) unter Verwendung von Schachbrett-Titration-ELISA untersucht wurden, um die optimale Antigenkonzentration und Serumverdünnung für die Herstellung von Diagnosekits zu bestimmen. Mit der indirekten ELISA-Methode wurden dann die diagnostischen Leistungswerte (DPV) (Sensitivität, Spezifität, diagnostische Effizienz, positiver prädiktiver Wert und negativer prädiktiver Wert) auf der Grundlage des Cutoff-Werts jedes Antigens mit Gesamt-IgG und seinen Unterklassen (IgG1 und IgG4) bewertet. Antigen B (AgB) wurde aus Hydatidenflüssigkeit gereinigt und elektrophoretisch behandelt, um seine Banden (8 kDa, 16 kDa und 24 kDa AgB) zu isolieren, die als Antigene verwendet wurden, zusätzlich zu einem aus Protoskolekten gereinigten Antigen. Von den 15 vorbereiteten Kits zeigten diejenigen, die die 8 kDa-Untereinheit von AgB und IgG4 enthielten, die beste Leistung. Die Ergebnisse der ROC-Kurve zeigten, dass die 8 kDa-Untereinheit die höchste diagnostische Genauigkeit aufwies, wenn sie mit IgG4 und IgG1 getestet wurde. Darüber hinaus umfasste diese Studie die Immunisierung von Kaninchen mit AgB, und die Ergebnisse deuteten darauf hin, dass AgB die Immunantwort in Richtung einer Th2-Neigung modulieren kann.

  • 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...

    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 ...
