Meredith et al. (Reports, 28 October 2011, p. 521) question three findings of our delayed-rise hypothesis for present-day mammals made with reference to the Cretaceous-Paleogene (KPg) boundary, based on their new time tree of the group. We show that their own data do not support their objections and that the macroevolutionary patterns from the respective phylogenies are not statistically differ...

Instead, they try to avoid responsibility and deny complicity, even for decisions that they ultimately approve. This paper examines two novels and a recent case from a neonatal intensive care unit ...

Os angiofibromas são os tumores vasculares histologicamente benignos mais frequentemente encontrados, com potencial destrutivo local, geralmente originários da parede lateral posterior da nasofaringe.
