Mechanism1
Conclusions: Lippia alnifolia essential oil has spasmolytic activity on isolated guinea-pig trachea and its mechanism of action possibly involves the activation of multiple signal transduction pathways, which culminate in potassium channels activation and cytosolic calcium reduction. (biofron.com)

Methods3
MATERIALS AND METHODS: The roots were provided by the Brazilian Federal Police, and the freeze-dried extract was used for the chemical analysis of the AqECsR by high performance liquid chromatography coupled with mass spectrometry (HPLC-MS). The sample was subsequently used in three doses for pharmacological assays (12.5, 25, and 50 mg/kg), which included the spasmolytic activity test and the primary dysmenorrhea test. (bvsalud.org)
In this study, we characterized U.S. meningococcal isolates (N = 201) from 15 epidemiologically defined outbreaks (2009-2015) along with temporally and geographically matched sporadic isolates using multilocus sequence typing, pulsed-field gel electrophoresis (PFGE), and six whole genome sequencing (WGS) based methods.
