Estudio microfacial, mineralógico, geoquímico e isotópico de la formación San Felipe (Cretácico Superior), Noreste de México.
Published 2018“…Based on the immobile elements geochemistry and Sm-Nd isotopic ratios, the San Felipe shale corresponds mainly to grauwaca that comes from an igneous felsic and/or quartzose sedimentary source linked to with continental arc setting and with a strong affinity to the continental crust (TNd = 41.8 a 698.3 Ma; ƐNd(0) = -6.2 a -0.1). Considering the petrographic and geochemical features the volcano-sedimentary material corresponds to rhyolite-riodacite, produced from a volcanic activity that occurred between 84.6 and 73.7 Ma, as result of the continental crust partial melting in a continental arc. …”

Efficacy of DA-7218, a new oxazolidinone prodrug, in the treatment of experimental actinomycetoma produced by nocardia brasiliensis
Published 2008“…We first determined the plasma concentration of the prodrug in BALB/c mice using several doses and then tested its activity in an in vivo experimental actinomycetoma murine model. At the end of treatment, there was a statistically significant difference between the three drug receiving groups (25, 12.5 and 5 mg/kg) and the control group (saline solution) (p=0.001), proving that DA-7218 is effective for the treatment of experimental murine actinomycetoma. …”
