Electrophysiological and Iontophoretic Aspects of the Habenular Influence on Hippocampal Neurones

1995

In previous experimental studies, carried out on cats, we demonstrated that electrical stimulation of lateral habenula (LH) at 0.5-3.0 Hz or 5-20 Hz had a double effect (low frequency-excitation; high frequency-inhibition) on the spontaneous firing rate of single hippocampal neurones. Our results, in agreement with similar case studies, allowed us to hypothesise that in the habenular modulation of the hippocampus the raphe nucleus is probably involved. In fact, all the effects of LH stimulation were antagonised by the iontophoretic intrahippocampal application of methysergide. In the present series of experiments, performed on rats, it was possible to demonstrate that LH stimulation at 1-10…

Two types of receptors for 5-hydroxytryptamine on the cholinergic nerves of the guinea-pig myenteric plexus

1985

Abstract The effects of 5-hydroxytryptamine (5-HT) on spontaneous and electrically-evoked release of [3H]-acetylcholine (ACh) from guinea-pig myenteric plexus preparations preincubated with [3H]-choline have been investigated in the absence of cholinesterase inhibitors. 5-HT caused a transient increase in spontaneous release and an inhibition of the electrically-evoked release of [3H]-ACh. The 5-HT-induced contractions of the longitudinal muscle were clearly related to the increase in spontaneous release. The inhibitory effect was not due to activation of alpha-adrenoceptors since it was also observed in the presence of tolazoline and on strips from reserpine-pretreated guinea-pigs. After d…

Involvement of prostaglandins and 5-hydroxytryptamine in the contractile effect of platelet-activating factor in rat isolated gastric corpus

1996

Abstract The present study characterizes the nature of the response to the platelet-activating factor (PAF) in isolated gastric corpus with and without mucosa. PAF (10-8 M) induced contraction of rat isolated gastric corpus strips followed by desensitization of this tissue. Incubation of strips with the specific PAF-receptor antagonist WEB 2086 (5 × 10-8 − 5 × 10-5 M), the prostaglandin blocker indomethacin (10-6 M) and the 5-hydroxytryptamine antagonist methysergide (10-5 M) reduced significantly the contraction induced by PAF. Neither of the histamine H1/H2 antagonists diphenhydramine (10-6 M) or cimetidine (10-5 M) affected the contraction induced by PAF. In contrast with the whole gastr…

Scelte terapeutiche e trattamento con sorafenib nell'epatocarcinoma: Analisi finale dello studio GIDEON in Italia

2015

Summary. Introduction. Sorafenib, an oral multikinase inhibitor, is the only targeted agent approved for the treatment of patients with hepatocellular carcinoma (HCC) after demonstration to increase overall survival compared to placebo in two randomized phase III study. GIDEON (Global Investigation of therapeutic DEcisions in HCC and Of its treatment with sorafeNib) is the largest, global, non-interventional, prospective study of patients with uHCC (n>3200) treated with sorafenib in real-life clinical practice conditions. Here we report the final analysis of safety and efficacy in the Italian cohort of patients. Methods. Patients with unresectable HCC who are candidates for systemic ther…

Contributo alla conoscenza del comportamento dei setti caricati orizzontalmente

2008

Si illustrano e si discutono i risultati di una prova di carico a rottura eseguita su un setto in vera grandezza realizzato in terreni sabbiosi. Il comportamento del sistema setto-terreni è fortemente non lineare a partire da valori del carico applicato dell’ordine di 1000 kN. Il carico orizzontale limite si raggiunge per valori dello spostamento in corrispondenza della testa del setto dell’ordine dei 10 cm, ed è principalmente governato dalla resistenza flessionale della sezione trasversale del setto.

Arte Tedesca e Arte Degenerata. Aspetti della politica culturale del Terzo Reich

2011

Il saggio prende le mosse dalle iniziative intraprese da Joseph Goebbels nell'ambito dell'organizzazione culturale in Germania, durante i primi mesi del "nuovo corso" nazista. Fra i vari temi, vengono affrontate le questioni relative alle rapporto con la cultura della Repubblica di Weimar, alle grandi mostre di Monaco (Entartete Kunst, 1937) e Duesselforf (Entartete Musik, 1938), nonché della produzione musicale all'interno del ghetto di Theresienstadt.

"Les années d'apprentissage" de Rudolf Kassner, essayiste à Vienne dans les années 1900

2017

International audience; Rudolf Kassner (1873-1959), ami de Hofmannsthal et de Rilke, est l'auteur d'une oeuvre imposante, composée de nombreux ouvrages rassemblés dans les dix volumes de l'édition critique élaborée par Ernst Zinn et Klaus E. Bohnenkamp. L'étude de ses "années d'apprentissage" dans la Vienne des années 1900, mais aussi à Londres et à Paris, permet d'aller à la rencontre d'un auteur qui a puisé, dans le climat intellectuel et artistique de cette époque, les fondements de sa riche et singulière réflexion sur l'art et le monde.

De l'ailleurs topographique et humaniste aux étrangetés narratives et génériques : Forster entre Meredith et le nouveau roman

2010

L'œuvre romanesque de Forster se définit avec une acuité particulière à travers les confluences sémantiques de l'étrange et de l'étranger. Un premier repérage des logiques géographiques et humanistes de ces concepts pour Forster, de Where Angels Fear to Tread à Maurice, permettra de mettre au jour leurs caractéristiques et leur rôle majeur au sein de l'intrigue forstérienne ainsi que dans la construction idéologique des personnages. Mais c'est dans A Passage to India, point d'orgue de cet œuvre autant que contrepoint à une écriture jusqu'alors moins audacieuse, que cette double dimension romanesque prend tout son sens. L'étrangeté du lieu indien conduit cette écriture vers de nouveaux topoï…

Modèle des voies réflexes et cérébelleuses, permettant le calcul de fonctions inverses et la commande d'un segment mécanique mobile

2004

14/07/2004; La commande et le contrôle des mouvements des membres par les voies cérébelleuses et réflexes sont modélisées au moyen d'un circuit dont la structure est déduite de contraintes fonctionnelles. 1/ La première contrainte est que les mouvements rapides des membres doivent être précis, quoiqu'ils ne puissent pas être commandés en boucle fermée au moyen de signaux sensoriels. Les voies qui préparent les ordres moteurs doivent donc contenir des fonctions inverses approximées des fonctions biomécaniques du membre et des muscles. Or une telle fonction peut être calculée au moyen de boucles de rétroaction parallèles, dont la structure est comparable à l'anatomie des voies cérébelleuses. …
