538 ms) and for conflict ratio (0.158 vs. 0.191). The latter difference mainly resulted from gender-specific variances of the conflict network

in opposite directions. The executive function as represented by the conflict network of visual attention of the ANT is affected in schizophrenia. We have detected hitherto unreported gender-specific differences between healthy controls and schizophrenic patients. Especially as regards the conflict network, the ANT offers a promising methodology to detect a neuropsychological endophenotype of schizophrenia. (C) 2008 Elsevier Ireland Ltd. All rights reserved.”
“Humoral immune responses are thought to play a major role in dengue virus-induced immunopathology; however, little is known about the plasmablasts producing NCT-501 supplier these antibodies during an ongoing infection. FRAX597 Herein we present an analysis of plasmablast responses in patients with acute dengue virus infection. We found very potent plasmablast responses that often increased more than 1,000-fold over the baseline levels in healthy volunteers.

In many patients, these responses made up as much 30% of the peripheral lymphocyte population. These responses were largely dengue virus specific and almost entirely made up of IgG-secreting cells, and plasmablasts reached very high numbers at a time after fever onset that generally coincided with the window where the most serious dengue virus-induced pathology is observed. The presence

of these large, rapid, and virus-specific plasmablast responses raises the question as to whether these cells might have a role in dengue immunopathology during the ongoing infection. These findings clearly illustrate the need for a detailed understanding of the repertoire and specificity of the antibodies that these plasmablasts produce.”
“Recent literature suggests that lying may be revealed by elevated cognitive effort. A functional magnetic resonance imaging experiment using a match-mismatch detection task was conducted that found tuclazepam support for this hypothesis in two ways. First, compared to truthful reporting, lying (i.e., responding that matches were mismatches or vice versa) triggered greater activation of the working memory network in the brain. This was especially true for lying about a match, where activation in the WM network was found to be greater than when lying about a mismatch. Lying also activated the right rostrolateral prefrontal cortex (BA 10) a key cognitive control region that regulates the interplay between stimulus-oriented and internally-generated schemas. Second, activation in the right inferior frontal gyrus (BA 44) – a brain region underpinning inhibition – predicted lying skill. The findings show that the neural correlates of cognitive effort and control can be used to detect lying, and that a specific neural marker of inhibition can predict how well one lies.
