A preliminary analysis of insects of medico-legal importance in Curitiba, State of Paraná.

abstract：:BACKGROUND The genus Flavivirus includes a variety of medically important viruses, including dengue virus (DENV) and Zika virus (ZIKV), which are most prevalent in Brazil. Because the clinical profile of patients affected by different DENV serotypes or ZIKV may be similar, the development of new methods that facilitat...

abstract：:Cytokines are important in the cell-mediated response to Schistosoma mansoni eggs. We have found that Th2 cytokine responses (e.g. IL-4 and IL-5) are augmented after egg laying begins while Th1 responses (IL-2 and IFN-gamma) are down regulated in S. mansoni infected mice. Treatment of mice with anti-IL-5 monoclonal an...
