Does dNA barcode detect high genetic structure within neotropical bird species?
The taxonomic uncertainty associated with the high incidence of non-monophyletic species and discovery of putative species obscures studies of historical patterns of species diversification in the Neotropical region. We showed that COI barcodes are a valuable tool to indicate which taxa would benefit from more extensive taxonomic revisions with multilocus approaches. Moreover, our results support hypotheses that the megadiversity of birds in the region is associated with multiple geographic processes starting well before the Quaternary and extending to more recent geological periods.
In mechanically ventilated pediatric ICU patients, PAI-1 is independently associated with the diagnosis of VAP. Real-time measurement of PAI-1 levels in bronchoalveolar lavage fluid may be of benefit in the early diagnosis and subsequent treatment of VAP in ICU patients.
