The specific involvement of the delta-opioid receptor in the control of nociception was explored by investigating the pharmacological activity in vivo of a selective, orally active, and centrally penetrant delta-opioid agonist. [8R-(4bS*,8aalpha,8abeta,12bbeta)]7,10-dimethyl-1-methoxy-11-(2-methylpropyl)oxycarbonyl(More)
Non-competitive N-methyl-d-aspartate (NMDA) blockers induce schizophrenic-like behavior in healthy volunteers and exacerbate symptomatology in schizophrenic patients. Hence, a compound able to enhance NMDA neurotransmission by increasing levels of d-serine, an endogenous full agonist at the glycine site of the NMDA receptors, could have anti-psychotic(More)
Increased glycogen synthase kinase-3 (GSK-3) activity is believed to contribute to the etiology of chronic disorders like Alzheimer's disease and diabetes, thus supporting therapeutic potential of GSK-3 inhibitors. However, sustained GSK-3 inhibition might induce tumorigenesis through beta-catenin-APC dysregulation. Besides, sustained in vivo inhibition by(More)
BACKGROUND Chronic cerebrospinal venous insufficiency (CCSVI) has been proposed as a possible cause of multiple sclerosis (MS). OBJECTIVES The CoSMo study evaluated the association between CCSVI and MS. METHODS The primary end-point of this multicentric, case-control study was to compare the prevalence of CCSVI between patients with MS, patients with(More)
(-)-cis-1-Methyl-7-[[4-(2,6-dichlorophenyl)piperidin-1-yl]methyl]-6,7,8,9-tetrahydro-5H-benzocyclohepten-5-ol (SB-612111) is a novel human opiate receptor-like orphan receptor (ORL-1) antagonist that has high affinity for the clonal human ORL-1 receptor (hORL-1 K(i) = 0.33 nM), selectivity versus mu-(174-fold), delta-(6391-fold), and kappa (486-fold)-opioid(More)
BACKGROUND Few data on services for people with severe multiple sclerosis (MS) are available. The Palliative Network for Severely Affected Adults with MS in Italy (PeNSAMI) developed a home palliative care program for MS patients and carers, preceded by a literature review and qualitative study (here reported). OBJECTIVE To identify unmet needs of people(More)
A gas chromatographic-mass spectrometric method for the qualitative and quantitative analysis of levodropropizine (S(-)-3-(4-phenyl-piperazin-1-yl)-propane-1,2-diol, DF 526) in plasma is described. The method proved to be highly selective and sensitive. Drug concentrations as low as 5 ng/ml could be measured. Levodropropizine plasma levels were measured in(More)
BACKGROUND Preliminary evidence suggests that palliative care may be useful for people with severe multiple sclerosis (MS). The aim of this study is to determine the effectiveness of a home-based palliative approach (HPA) for people with severe MS and their carers. METHODS/DESIGN This is a single-blind randomized controlled trial with a nested qualitative(More)
Protein tyrosine phosphatase receptor type Z (Ptprz) is widely expressed in the mammalian central nervous system and has been suggested to regulate oligodendrocyte survival and differentiation. We investigated the role of Ptprz in oligodendrocyte remyelination after acute, toxin-induced demyelination in Ptprz null mice. We found neither obvious impairment(More)
We hypothesized that the up-regulated expression of one or more members of the regulator of G protein signaling (RGS) family can cause an attenuation of signaling via Gi/Go-coupled opioid receptors, and thereby play a role in the development of hyperalgesia and accompanying insensitivity to morphine observed in animal models of neuropathic pain.(More)
