Aiming at providing high-class evidence regarding the use of intraoperative MRI (ioMRI), we are conducting a prospective randomized controlled trial. Adult patients with contrast enhancing lesions suspicious of malignant gliomas scheduled to undergo radiologically complete tumor resection are eligible to enter this trial. After giving their informed(More)
Protein palmitoylation in vitro was studied using bovine rhodopsin as the substrate and a partially purified acylating enzymatic activity (PAT) from placental membranes. PAT incorporates fatty acid into rhodopsin with higher efficiency (10 times higher initial rate), as compared to autoacylation. The activity is sensitive to heat and trypsin, indicating a(More)
BACKGROUND The use of smart phones within medicine continues to grow at the same rate as mobile phone technology continues to evolve. One use of smart phones within medicine is in the transmission of radiological images to consultant neurosurgeons who are off-site in an emergency setting. In our unit, this has allowed quick, efficient, and safe(More)
BACKGROUND Accurate positioning of a ventricle catheter is of utmost importance. Various techniques to ensure optimal positioning have been described. Commonly, after catheter placement, additional manipulation is necessary to connect a burr hole reservoir or shunt components. This manipulation can lead to accidental catheter dislocation and should be(More)
Dabigatran etexaliate is a novel oral anticoagulant that directly inhibits thrombin. It offers a number of substantial medical benefits over other oral and parenteral anticoagulants but its advent raises important neurosurgical considerations. Dabigatran has important potential benefits. Unlike warfarin, it does not require routine blood tests to monitor(More)
BACKGROUND Devices enabling long-term intracranial pressure monitoring have been demanded for some time. The first solutions using telemetry were proposed in 1967. Since then, many other wireless systems have followed but some technical restrictions have led to unacceptable measurement uncertainties. In 2009, a completely revised telemetric pressure device(More)
