Discovery and characterization of two novel CB1 receptor splice variants with modified N-termini in mouse
2017
Numerous studies have been carried out in the mouse model, investigating the role of the CB1 cannabinoid receptor. However, mouse CB1 (mCB1) receptor differs from human CB1 (hCB1) receptor in 13 amino acid residues. Two splice variants, hCB1a and hCB1b, diverging in their amino-termini, have been reported to be unique for hCB1 and, via different signaling properties, contribute to CB1 receptor physiology and pathophysiology. We hypothesized that splice variants also exist for the mCB1 receptor and have different signaling properties. On murine hippocampal cDNA, we identified two novel mCB1 receptor splice variants generated by splicing of introns with 117 bp and 186 bp in the N-terminal dom…
Cellular mechanisms of IL-17-induced blood-brain barrier disruption.
2009
Recently T-helper 17 (Th17) cells were demonstrated to disrupt the blood-brain barrier (BBB) by the action of IL-17A. The aim of the present study was to examine the mechanisms that underlie IL-17A-induced BBB breakdown. Barrier integrity was analyzed in the murine brain endothelial cell line bEnd.3 by measuring the electrical resistance values using electrical call impedance sensing technology. Furthermore, in-cell Western blots, fluorescence imaging, and monocyte adhesion and transendothelial migration assays were performed. Experimental autoimmune encephalomyelitis (EAE) was induced in C57BL/6 mice. IL-17A induced NADPH oxidase- or xanthine oxidase-dependent reactive oxygen species (ROS)…

Results from a prospective observational study of men with premature ejaculation treated with dapoxetine or alternative care: The PAUSE study
2014
Abstract Background Dapoxetine hydrochloride is a selective serotonin reuptake inhibitor and the first drug approved for the on-demand treatment of premature ejaculation (PE). Its safety was established in a thorough clinical development program. Objective To characterize the safety profile of dapoxetine in PE treatment and to report the incidence, severity, and type of adverse events. Design, setting, and participants We conducted a 12-wk, open-label, observational study with a 4-wk, postobservational contact. A total of 10 028 patients were enrolled, with 6712 patients (67.6%) treated with dapoxetine 30–60mg (group A)and 3316 (32.4%) treated with alternative care/nondapoxetine (group B). …
Premature ejaculation: Pharmacotherapy vs group psychotherapy alone or in combination
2017
Objectives: Premature Ejaculation (PE), the commonest sexual dysfunction in males, is generally treated with local anesthetic and SSRI (Dapoxetine). The aim of our study was investigate Group Psychotherapy as an alternative treatment for PE and compare the efficacy of pharmacological treatment and psychotherapy, either alone or in combination, in terms of response and improved Quality of Life (QoL). From a male outpatient population screened for PE, those who received a diagnosis of PE were proposed for the study, enrolled and divided into 3 groups (A, B and C). Each group was treated with Dapoxetine, Group Psychotherapy alone and Dapoxetine and Group Psychotherapy, respectively. Materials …
German randomized double-blind multicentre comparison of terbinafine and itraconazole for the treatment of toenail tinea infection
1996
Summary One–hundred and ninety–five patients with toenail tinea unguium were recruited to a multicentre double–blind clinical trial. Patients were given 250mg terbinafine or 200 mg itraconazole daily for 12 weeks, with follow–up for a further 40 weeks. At the end of the study, mycological cure rates were 81% (70/86 assessed) for terbinafine and 63% (53/84 assessed) for itraconazole (two–tailed, P < 0·05). The length of unaffected nail was 9·44 mm in the terbinafine group and 7·85 mm in the itraconazole group (two–tailed, P < 0·05). Patient self–assessment also favoured terbinafine, with 65% evaluating it as good to very good, compared with 58% for itraconazole. Before treatment the terbinaf…
Compliance to therapy with Dapoxetine in patients affected by Premature Ejaculation
2012
Introduction Premature ejaculation (PE) is a sexual dysfunction with high prevalence. According to some reports, it is present in about 20-30% of the male population. Since 2009 PE has been treated with a novel inhibitor of serotonin re-uptake, Dapoxetine, which has been reported to be specifically active for PE. Materials and Methods 59 patients have been selected among the patients affected by PE observed at the outpatient department of Urology and Andrology of the “Paolo Giaccone” University Policlinic Hospital of Palermo. Diagnosis was confirmed unequivocally in all patients, who were suitable for drug treatment and accepted to participate in the study. They were divided in 2 groups: on…
Cannabinoid and nitric oxide signaling interplay in the modulation of hippocampal hyperexcitability: study on electrophysiological and behavioral mod…
2015
A growing bulk of evidence suggests that cannabinoid system plays a pivotal role in the control of hyperexcitability phenomena. Notwithstanding, the anticonvulsant action of cannabinoids has not been fully addressed, in particular the involvement of potential cellular neuromodulators, for instance nitric oxide. In the current study, we focused on two distinct rat models of temporal lobe epilepsy, the Maximal Dentate Activation and the pilocarpine-induced acute seizures, providing both electrophysiological and behavioral data on cannabinoid and nitrergic system interplay. We evaluated the antiepileptic effects of WIN 55,212-2, (R)-(+)-[2,3-dihydro-5-methyl-3-(4- morpholinylmethyl) pyrrolo[1,…
Evidences of cannabinoids-induced modulation of paroxysmal events in an experimental model of partial epilepsy in the rat.
2009
The anticonvulsant effect of cannabinoids (CB) has been shown to be mediated by the activation of the CB(1) receptor. This study evaluates the anticonvulsant activity of (R)-(+)-[2,3-dihydro-5-methyl-3-(4-morpholinylmethyl) pyrrolo[1,2,3-de]-1,4-benzoxazin-6-Yl]-1-naphthalenylmethanone (WIN55,212-2, CB agonist) alone or preceded by the administration of N-(piperidin-1-yl)-5-(4-iodophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole-3-carboxamide (AM251, selective CB(1) antagonist) in an experimental in vivo model of complex partial seizures (maximal dentate gyrus activation - MDA) in the rat. WIN55,212-2 (21mgkg(-1)) exerted an anticonvulsant effect, significantly reduced by the pre-treatme…
Effects of Cannabinoid Exposure during Adolescence on the Conditioned Rewarding Effects of WIN 55212-2 and Cocaine in Mice: Influence of the Novelty-…
2016
Adolescent exposure to cannabinoids enhances the behavioural effects of cocaine, and high novelty-seeking trait predicts greater sensitivity to the conditioned place preference (CPP) induced by this drug. Our aim was to evaluate the influence of novelty-seeking on the effects of adolescent cannabinoid exposure. Adolescent male mice were classified as high or low novelty seekers (HNS and LNS) in the hole-board test. First, we evaluated the CPP induced by the cannabinoid agonist WIN 55212-2 (0.05 and 0.075 mg/kg, i.p.) in HNS and LNS mice. Then, HNS and LNS mice were pretreated i.p. with vehicle, WIN 55212-2 (0.1 mg/kg), or cannabinoid antagonist rimonabant (1 mg/kg) and were subsequently con…
