[Usefulness and Problems of Intraoperative Monitoring for Unruptured Aneurysm Surgery with the Motor Evoked Potential].

It has been pointed out that the motor evoked potential(MEP)with a subdural electrode is useful in the intraoperative monitoring for unruptured aneurysm surgery. However, in some cases, we experienced postoperative ischemic complications despite evaluating the motor function via MEP monitoring. Herein, we have reported the usefulness and problems of intraoperative monitoring with MEP to evaluate brain dysfunction caused by insufficiency of cerebral blood flow.

Magnesium uptake of Arabidopsis transporters, AtMRS2-10 and AtMRS2-11, expressed in Escherichia coli mutants: Complementation and growth inhibition by aluminum.

Magnesium (Mg2+) plays a critical role in many physiological processes. Mg2+ transport systems in Salmonella have been well documented, but those in Escherichia coli have not been fully elucidated. We examined the effects of corA, mgtA, yhiD and corC gene deletion on Mg2+ transport in E.
