Interindividual variability and drug interaction studies suggest that blood-brain barrier drug transporters mediate human methadone brain biodistribution. In vitro and animal studies suggest that methadone is a substrate for the efflux transporter P-glycoprotein, and that P-glycoprotein-mediated transport influences brain access and pharmacologic effect. This investigation tested whether methadone is a transporter substrate in humans [corrected]. ⋯ Cyclosporine did not affect methadone pharmacodynamics. This result does not support a role for cyclosporine-inhibitable transporters mediating methadone brain access and biodistribution.

Myeloid differentiation factor 88 (MyD88) is an adaptor molecule critical for host innate immunity. Studies have shown that signaling via MyD88 contributes to cytokine storm, cardiac dysfunction, and high mortality during endotoxin shock.However, the specific contribution of MyD88 signaling of immune and cardiac origins to endotoxin shock remains unknown. ⋯ Both cardiomyocyte- and myeloid-MyD88 signaling play a role in cardiac dysfunction and mortality during endotoxin shock. Myeloid-MyD88 signaling plays a predominant role in systemic and cardiac inflammation after endotoxin challenge.

49 Mathoura Road: Geoffrey Kaye's Letters to Paul M. Wood, 1939-1955.
From 1930 to 1955, Geoffrey Kaye, M. B. B. ⋯ He believed that the diffusion center which "49" was to become was not only realistic and achievable but also necessary if Australian anesthesia was to gain international prominence comparable to anesthesia in Europe and North America. In the end, the failure of "49" left Kaye estranged from Australian anesthesia for many years. How this estrangement affected Australian anesthesia is unknown.
