Neuropathic pain is a clinical manifestation of nerve injury difficult to treat even with potent analgesic compounds. Here, we used different lines of genetically modified mice to clarify the role played by CB(2) cannabinoid receptors in the regulation of the central immune responses leading to the development of neuropathic pain. CB(2) knock-out mice and(More)
Nerve injuries often lead to neuropathic pain syndrome. The mechanisms contributing to this syndrome involve local inflammatory responses, activation of glia cells, and changes in the plasticity of neuronal nociceptive pathways. Cannabinoid CB(2) receptors contribute to the local containment of neuropathic pain by modulating glial activation in response to(More)
Epidemiological studies help to establish the health status in a country and allow a better allocation of economic resources. This survey estimated pain prevalence in Catalonia (Spain), analysed its relationship with demographic variables and evaluated pain-associated disabilities. The study was carried out in 1964 adults via phone interviews asking about(More)
The aim of this survey was twofold: to assess the willingness of medical students to volunteer for clinical trials and to evaluate the weight of the financial reward and other general details as seen by healthy volunteers who had already participated in clinical trials. A specific questionnaire was given to each group to be answered anonymously. Among the(More)
BACKGROUND AND PURPOSE Little is known about the factors that determine recanalization after intravenous thrombolysis. We assessed the value of thrombus Hounsfield unit quantification as a predictive marker of stroke subtype and MCA recanalization after intravenous rtPA treatment. MATERIALS AND METHODS NCCT scans and CTA were performed on patients with(More)
The effects of acute administration of dizocilpine (MK-801) at different perioperative times on autotomy behavior after sciatic and saphenous nerve transection were studied in the mouse. Control mice developed a severe self-mutilating behavior starting 1-3 days postoperation and reaching a maximum by 11 days. Mice injected with a single dose of dizocilpine(More)
1. The actions of the trivalent cation, gadolinium (Gd3+), were studied on frog isolated neuromuscular preparations by conventional electrophysiological techniques. 2. Gd3+ (450 microM) applied to normal or formamide-treated cutaneous pectoris nerve-muscle preparations induced, after a short delay, a complete block of neuromuscular transmission. The(More)
Guanidine has been shown to potentiate neurotransmission at the skeletal neuromuscular junction. The present study was undertaken to evaluate whether reductions in extracellular calcium affect the action of guanidine on the reversal of neuromuscular blockade induced by dibekacin and d-tubocurarine in the rat phrenic-hemidiaphragm preparation. Guanidine(More)
The research of new therapeutic strategies for neuropathic pain represents a major current priority. Important drawbacks to advance in the development of these therapies are the limited translational value of the animal models now available and the elucidation of the complex neuronal and immune pathophysiological mechanisms underlying neuropathic pain.

subunidades distintas, llamadas α 2 δ-1, α 2 δ-2 y α 2 δ-3, pero la G B P se une sólo a las dos primeras, especialmente a la α 2 δ-1 (11). Así, al fijarse a la subunidad α 2 δ, la GBPbloquea la entrada de calcio a través de los canales de calcio presinápticos, especial-mente los Py Q (12,13), pero también los L(14). De esta manera, se inhibiría la(More)
