The dorsomedial nucleus of the hypothalamus (DMH) has been proposed to participate in stress-induced hyperalgesia through facilitation of pronociceptive cells in the rostroventromedial medulla (RVM). We hypothesized that the DMH participates in hyperalgesia induced by arthritis. The DMH was pharmacologically manipulated while assessing heat-evoked(More)
Evidence from experimental pain research has revealed that metabotropic glutamate receptors (mGluRs) play a pivotal role in nociceptive processing, inflammatory pain and hyperalgesia. The aim of this study was to characterise expression of group I and II mGluRs in spinal cord in a model of naturally occurring persistent inflammation (sheep with unilateral(More)
A good deal of research on learning introductory programming have been carried out along the past years based on a generalization to mature individuals of Piaget's theory which states that learning among childrens progresses from concrete to abstract. In this research, we set up two problem domains -- a concrete and an abstract one -- along with specific(More)
This paper presents a way of constructing a multi-agent nonmonotonic logic from any propositional preference logic (the base logic). The multi-agent logic will \correctly" extend the base logic for each agent, that is, each agent will reason in the base logic, and the reasoning of each agent is independent of each other. If the base logic is propositional(More)
Tissue damage during surgery can induce 'central sensitization' and the development of pain and hyperalgesia post-operatively. Metabotropic glutamate receptors (mGluRs) contribute to nociception, inflammatory pain and hyperalgesia. This study characterized the temporal expression of group I (mGluR(1), mGluR(5)) and II (mGluR(2), mGluR(3)) mGluRs in spinal(More)
expressão do gene codificador da enzima EPSPS-2 como mecanismo de resistência ao glifosato. Abstract This dissertation reports the study of two resistance mechanisms in a glyphosate-resistant Conyza canadensis population (B15), comparatively with a susceptible population (B), from intensive olive orchards in Alentejo (south of Portugal). Initially, the(More)
