Therefore, we compared the efficacy and safety of the rofecoxib, which specifically inhibits COX-2, with those(More)

We evaluated the phylogenetic and morphological relationships between species and individuals (i.e., inter- and intraspecific variability) of Neotropical nonvolant small mammals(More)
