This survey suggests that NPS are likely to be added to drug repertoires, particularly amongst experienced users with consequent health risks for individuals and resource implications for services. This study points to a complex relationship between NPS and illegal drug availability, purity and regulatory control, one which is increasingly important to understand given the global emergence of NPS and the challenges they present to existing supply, demand and harm reduction strategies.
These data suggest that human endothelium, a key component of all vital organs, is receptive to protection by sevoflurane in vivo. Peri-ischemic administration of sevoflurane mimics a combination of pharmacologic preconditioning and postconditioning and protects at even low sedative concentrations (< 1 vol%). Inhibition of leukocyte adhesion is likely to be involved in the protection.
