In order to determine whether behavioral responses to opiates were dependent on the same receptor subtypes, we tested GalR1 and GalR2 knockout mice for morphine conditioned place preference (CPP). Morphine CPP was significantly attenuated in both GalR1 and GalR2 knockout mice. These data suggest that mesolimbic excitatory signaling is significantly modulated by galanin in a GalR1-dependent and GalR2-dependent
manner, and that morphine CPP is dependent on the same receptor subtypes.”
“During gain adaptation, participants must learn to adapt to novel visuo-motor mappings in which the movement amplitudes they produce do not match the visual feedback they receive. selleck chemicals The aim of the present study was to investigate the neural substrates of gain adaptation by examining its possible disruption following left hemisphere learn more stroke. Thirteen chronic left hemisphere stroke patients and five healthy right-handed control subjects completed three experimental phases involving reaching with the left hand,
which was the less-affected hand in patients. First, participants reached without visual feedback to six different target locations (baseline phase). Next, in the adaptation phase, participants executed movements to one target under conditions in which the perceived movement distance was 70% of the produced movement distance. Last, in order to test the generalization of this new visuomotor mapping, participants made movements without visual feedback to untrained target locations (generalization phase). Significant between-patient differences were observed during adaptation. selleck products Lesion analyses indicated that these between-patient differences were predicted by the amount of damage to the supramarginal gyrus (Brodmann area 40). In addition, patients performed
more poorly than controls in the generalization phase, suggesting that different processes are involved in adaptation and generalization periods. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
“Clinical outcome of diffuse large B-cell lymphoma (DLBCL) patients with hepatitis C virus (HCV) infection in the rituximab era remains unclear. The aim of the present study was to compare the clinical outcome, treatment response and hepatotoxicity in DLBCL patients who received rituximab containing immunochemotherapy that had HCV infection and those that did not have HCV infection between January 2004 and October 2011. Of the 272 consecutive histopathologically diagnosed DLBCL patients in our department, a total of 248 were retrospectively analyzed in the present study. There were 28 DLBCL patients with HCV infection (the HCV group) and 220 DLBCL patients without HCV infection (the control group). We compared overall survival (OS), progression-free survival (PFS), treatment response and hepatotoxicity according to HCV infection. In terms of OS (P=0.
