Primary CNS lymphoma patient-derived orthotopic xenograft model capture the biological and molecular characteristics of the disease.

Blood Cells Mol Dis 2018 Nov 16;75:1-10. Epub 2018 Nov 16.

Institut Curie, Site Saint-Cloud Hematology, Saint-Cloud, France. Electronic address:

Primary CNS lymphomas (PCNSL) are rare and poor prognosis diffuse large B-cell lymphomas. Because of the brain tumor environment and the restricted distribution of drugs in the CNS, specific PCNSL patient-derived orthotopic xenograft (PDOX) models are needed for preclinical research to improve the prognosis of PCNSL patients. PCNSL patient specimens (n = 6) were grafted in the caudate nucleus of immunodeficient nude mice with a 83% rate of success, while subcutaneous implantation in nude mice of human PCNSL sample did not generate lymphoma, supporting the role of the brain microenvironment in the PCNSL physiopathology.

Impaired Tactile Temporal Discrimination in Patients With Hepatic Encephalopathy.

Front Psychol 2018 30;9:2059. Epub 2018 Oct 30.

Institute of Clinical Neuroscience and Medical Psychology, Medical Faculty, Heinrich Heine University Düsseldorf, Düsseldorf, Germany.

The sensory system constantly receives stimuli from the external world. To discriminate two stimuli correctly as two temporally distinct events, the temporal distance or stimulus onset asynchrony (SOA) between the two stimuli has to exceed a specific threshold. If the SOA between two stimuli is shorter than this specific threshold, the two stimuli will be perceptually fused and perceived as one single stimulus. Read More

Connecting occipital alpha band peak frequency, visual temporal resolution, and occipital GABA levels in healthy participants and hepatic encephalopathy patients.

Neuroimage Clin 2018 9;20:347-356. Epub 2018 Aug 9.

Institute of Clinical Neuroscience and Medical Psychology, Medical Faculty, Heinrich Heine University Düsseldorf, 40225 Düsseldorf, Germany.

Recent studies have proposed a connection between the individual alpha band peak frequency and the temporal resolution of visual perception in healthy human participants. This connection rests on animal studies describing oscillations in the alpha band as a mode of phasic thalamocortical information transfer for low-level visual stimuli, which critically relies on GABAergic interneurons. Here, we investigated the interplay of these parameters by measuring occipital alpha band peak frequency by means of magnetoencephalography, visual temporal resolution by means of behavioral testing, and occipital GABA levels by means of magnetic resonance spectroscopy.

Neuropsychologia 2018 Aug 11;117:46-54. Epub 2018 May 11.

Institute of Experimental Psychology, Heinrich-Heine University Düsseldorf, Germany.

Phasic dopamine (DA) signals conveyed from the substantia nigra to the striatum and the prefrontal cortex crucially affect learning from feedback, with DA bursts facilitating learning from positive feedback and DA dips facilitating learning from negative feedback. Consequently, diminished nigro-striatal dopamine levels as in unmedicated patients suffering from Parkinson's Disease (PD) have been shown to lead to a negative learning bias. Recent studies suggested a diminished striatal contribution to feedback processing when the outcome of an action is temporally delayed. Read More

J-difference-edited MRS measures of γ-aminobutyric acid before and after acute caffeine administration.

Magn Reson Med 2018 May 12. Epub 2018 May 12.

Department of Diagnostic and Interventional Radiology, Medical Faculty, Heinrich Heine University Düsseldorf, Düsseldorf, Germany.

Purpose: The aim of this study was to investigate potential effects of acute caffeine intake on J-difference-edited MRS measures of the primary inhibitory neurotransmitter γ-aminobutyric acid (GABA).

Methods: J-difference-edited Mescher-Garwood PRESS (MEGA-PRESS) and conventional PRESS data were acquired at 3T from voxels in the anterior cingulate and occipital area of the brain in 15 healthy subjects, before and after oral intake of a 200-mg caffeine dose. MEGA-PRESS data were analyzed with the MATLAB-based Gannet tool to estimate GABA+ macromolecule (GABA+) levels, while PRESS data were analyzed with LCModel to estimate levels of glutamate, glutamate+glutamine, N-acetylaspartate, and myo-inositol.

Three-years outcomes of diabetic patients treated with coronary bioresorbable scaffolds.

BMC Cardiovasc Disord 2018 May 10;18(1):92. Epub 2018 May 10.

Kardiologie I, Zentrum für Kardiologie, German Center for Cardiac and Vascular Research (DZHK), Standort Rhein-Main, University Hospital Mainz, Langenbeckstraße 1, 55131, Mainz, Germany.

Background: Diabetes is among the strongest predictors of outcome after coronary artery stenting and the incidence of negative outcomes is still high in this specific group. Data of long-term outcomes comparing diabetic patients with non-diabetic patients treated with bioresorbable scaffolds are still incomplete. This work evaluates the long-term outcomes after implantation of a coronary bioresorbable scaffold (BRS) in diabetic patients compared to non-diabetics. Read More

Less is more - Pulse width dependent therapeutic window in deep brain stimulation for essential tremor.

Brain Stimul 2018 Sep - Oct;11(5):1132-1139. Epub 2018 Apr 26.

Department of Neurology, Center for Movement Disorders and Neuromodulation, Medical Faculty, Heinrich-Heine University, Düsseldorf, Germany; Institute of Clinical Neuroscience and Medical Psychology, Medical Faculty, Heinrich-Heine University, Düsseldorf, Germany. Electronic address:

Background: Shorter pulse widths than conventional pulse width settings may lead to reduction of side effects and therefore be a valuable therapeutic option for deep brain stimulation (DBS) in patients with essential tremor (ET).

Objective: To compare the DBS effect of shorter pulse width at 40 μs (DBS-40 μs) to conventional pulse width at 60 μs (DBS-60 μs) on the therapeutic window in ET patients.

Methods: For this prospective, randomized, double-blind, crossover study 9 ET patients with chronic DBS of the ventral intermediate nucleus (VIM)/posterior subthalamic area (PSA) were recruited. Read More

Pallidal deep brain stimulation in juvenile Huntington's disease: local field potential oscillations and clinical data.

J Neurol 2018 Jul 3;265(7):1573-1579. Epub 2018 May 3.

Department of Neurology, Centre for Movement Disorders and Neuromodulation, Medical Faculty, Heinrich-Heine-University Düsseldorf, Moorenstrasse 5, 40225, Düsseldorf, Germany.

Background: Recently, therapeutic attempts to control motor choreatic hyperkinesia of Huntington's disease (HD) by means of pallidal deep brain stimulation (Gp-DBS) were successful. With respect to the clinical effects of Gp-DBS in juvenile hypokinetic-rigid HD (jHD; Westphal variant), only one single-case has been reported up to date. Oscillatory patterns of the Gp in jHD are not known. Read More
