Converging evidence from animal and human studies suggest that rapid eye movement (REM) sleep modulates emotional processing. The aim of the present study was to explore the effects of selective REM sleep deprivation (REM-D) on emotional responses to threatening visual stimuli and their brain correlates using functional magnetic resonance imaging (fMRI).(More)
Diazepam (DZ), a clinically important drug, reduces alertness and can interfere with complex cognitive processes. The effect of DZ on the behavioural and neural correlates of rule-guided response selection has not been directly investigated. We studied DZ effects, compared to placebo (PL), on performance and brain responses, using fMRI, during rule(More)
The wheat leaf apoplast contains a protein that inhibits trypsin and belongs to the family of germin-like proteins called germin-like protease inhibitor (GLPI). Since it was first described in our laboratory, the objective of this study was to find out if GLPI is a new germin-like protein and to identify the molecular site responsible for its inhibitory(More)
Daily life events confront us with new situations demanding responses to usual and unusual rules. Diazepam (DZ), a clinically important drug, facilitates the inhibitory activity of the GABAergic system. Prefrontal cortex, rich in DZ receptors, coordinates necessary resources to direct actions according to rules. The balance between excitatory and inhibitory(More)
We now know that eating fish regularly protects against heart disease and dying suddenly from a heart attack. This is because the oils in fish are unique—they have long-chain omega-3s, fatty acids found in few other foods. Fish omega-3s improve the way the heart works and make other conditions that contribute to heart disease less dangerous. For these(More)
Ubiquitin-like proteins (Ubls) and ubiquitin-like domain-containing proteins (Ulds) found in both eukaryotes and prokaryotes display an ubiquitin fold. We previously characterized a 124-amino acid polypeptide (P400) from the haloalkaliphilic archaeon Natrialba magadii having structural homology with ubiquitin family proteins. The reported N. magadii’s(More)
In this work a read out electronics prototype for reconstruction of two-dimensional images based on Field Programmable Gate Arrays (FPGAs) is presented. The front-end includes two main modules, the data acquisition electronics and a hardware architecture for data processing. The read out electronics consists mainly of a Resistive Chain, analog-to-digital(More)
BACKGROUND Word reading involves several steps, from the visual perception of each of its constitutent elements to its recognition as an entity with a specific meaning. Various brain structures participate in these processes, depending of the linguistic and cognitive characteristics of the stimulus. Our objective was to characterize brain activity through(More)
