The effects of 2,2,2-trichloroethanol, the active compound of the sedative-hypnotic chloral hydrate, were investigated on N-methyl-D-aspartate (NMDA)-induced increases in intracellular Ca2+ concentration ([Ca2+]i) in cultured mesencephalic and cortical neurones by means of the fura-2 method. Trichloroethanol inhibited the NMDA response in a(More)
OBJECTIVE Partial volume effects caused by limited spatial resolution of conventional positron emission tomography (PET) scanners result in an underestimation of the activity concentration in small tumours. The aim of the study was to evaluate the feasibility of small animal tumour imaging with the clinical PET scanner ECAT EXACT after partial volume(More)
OBJECTIVES While clinically the safety and efficacy of waterjet resection of brain tumors have been shown, evidence that waterjet dissection improves tumor resection radicality in comparison with conventional techniques is still missing. In the present study, resection radicality and tumor-free long-term survival of both techniques were evaluated in a(More)
PURPOSE Image registration is one prerequisite for the analysis of brain regions in magnetic-resonance-imaging (MRI) or positron-emission-tomography (PET) studies. Diffeomorphic anatomical registration through exponentiated Lie algebra (DARTEL) is a nonlinear, diffeomorphic algorithm for image registration and construction of image templates. The goal of(More)
INTRODUCTION Evaluation of new surgical techniques in animal models is frequently challenging. This article describes the pitfalls, peculiarities and the final best applicable model for evaluating surgical techniques for glioma resection. METHODS The C6 glioma cell line and the Sprague-Dawley rat strain were selected. Fifty-thousand glioma cells were(More)
