The interferance of muscarinic receptors with the noradrenaline release from sympathetic nerve endings caused by nicotinic agents.
1968
Characterization of choline efflux from the perfused heart at rest and after muscarine receptor activation.
1986
The resting efflux of choline from perfused chicken hearts varied from 0.4 to 2.6 nmol/g min, but was constant for at least 80 min in the individual experiments. The rate of choline efflux was found to be equal to the rate of choline formation in the heart, which, from the following reasons, was essentially due to hydrolysis of choline phospholipids. Cardiac content of choline phospholipids (7,200 nmol/g) was much higher than that of acetylcholine (5.5 nmol/g). Resting release of acetylcholine was 0.016 nmol/g min and, after inhibition of cholinesterase, only about 0.1 nmol/g min. Resting efflux of choline was reduced by mepacrine, a phospholipase A2 inhibitor, by perfusion with a Ca2+-free…
Fluorescence-guided bone resection by using Visually Enhanced Lesion Scope in diffuse chronic sclerosingosteomyelitis of the mandible: Clinical and p…
2015
Diffuse chronic sclerosingosteomyelitis (DCSO) is a refractory disease, becausethe etiology and pathogenesis remain poorly understood and to determine the border betweenunhealthy boneandhealthybone is difficult. However, progressive inflammation, clinical symptoms and a high recurrence rate of DCSO were the reasons for surgical treatment. We report a case of a 66-year old woman with DCSO of the right side of mandible who was treated with hemimandibulectomy and simultaneous reconstruction by vascularized free fibula flap. After preoperative administration of minocycline for 1 month, the bone fluorescence was successfully monitored by using a Visually Enhanced Lesion Scope (VELscope®). Intrao…
Advances in surfaces and osseointegration in implantology. Biomimetic surfaces
2015
The present work is a revision of the processes occurring in osseointegration of titanium dental implants according to different types of surfaces -namely, polished surfaces, rough surfaces obtained from subtraction methods, as well as the new hydroxyapatite biomimetic surfaces obtained from thermochemical processes. Hydroxyapatite’s high plasma-projection temperatures have proven to prevent the formation of crystalline apatite on the titanium dental implant, but lead to the formation of amorphous calcium phosphate (i.e., with no crystal structure) instead. This layer produce some osseointegration yet the calcium phosphate layer will eventually dissolve and leave a gap between the bone and …
Uusien 5G-teknologioiden energiatehokkuus
2016
Mobiiliverkkojen datamäärän kasvaessa räjähdysmäisesti tarvitaan uutta 5G-teknologiaa lisäämään langattomien verkkojen kapasiteettia. 5G-verkkoja kehitettäessä yksi tärkeä tutkimuskysymys on, kuinka saada niistä energiatehokkaita. Tässä tutkielmassa käydään läpi tieteellistä keskustelua aiheesta. Tieteellisestä keskustelusta keskeisimmiksi teknologioiksi 5G-verkkoihin nousevat muun muassa laitteistotekniikan kehittyminen, millimetriaallot, kognitiivinen radioverkko, massiivinen MIMO ja heterogeeninen verkko. Tarvitaan kuitenkin lisää tutkimusta ja kehitystyötä, jotta uusista 5G-verkoista saadaan riittävän energiatehokkaita. The amount of mobile data will grow radically and that's why we nee…
La mente del bambino: tra lungimiranza pedagogica ed evidenze neuroscientifiche. Uno studio comparato su Maria Montessori e la Brain-based Education
2021
Il paper intende tracciare una linea di congiunzione tra le intuizioni di Maria Montessori e le recenti evidenze neuroscientifiche: “La scoperta del bambino”, auspicata dalla studiosa all’inizio del XX secolo, è tuttora in corso e punta alla conquista della comprensione del funzionamento della mente del bambino. In particolare, la riflessione si sviluppa attorno ai seguenti temi: neuroplasticità neuronale e sinaptogenesi, lo sviluppo motorio, il processo attentivo e il meccanismo della mimesi. Questi argomenti, rinvigoriti dal dialogo tra la pedagogia montessoriana e le ricerche neuroscientifiche, possono determinare un nuovo modo di intendere la questione e la prassi educativa. The paper i…
Le caratteristiche dell’insegnante Montessori e l’apprendimento per imitazione: un’indagine sulle prassi degli insegnanti
2022
Maria Montessori nel suo percorso verso la delineazione del Metodo che prende il suo nome, enfatizza il ruolo dell’insegnante, la sua opera maieutica e puerocentrica. Il meccanismo della mimesi e l’apprendimento per imitazione rappresentano un caposaldo, oltre che una tra le modalità d’apprendimento più produttive nei primi mesi di vita del bambino. La commistione tra le recenti scoperte sul funzionamento del cervello e i principi guida del Metodo Montessori sono alla base dell’indagine quali-quantitativa svolta con 459 docenti di scuola primaria e scuola dell’infanzia di venti scuole siciliane durante l’A.S. 2020/2021. L’obiettivo dell’indagine è rilevare e misurare le prassi quotidiane de…
Antiikki viihteellisti retoriikan - entä me? : nykyajan medioituneen viestinnän ja antiikin retoriikan vertailua

O analogiji i teoriji etimona u hebrejskome biblijskom leksiku
2012
Dans le débat sur l’iconicité du langage, l’une des questions qui se posent d’une manière récurrente est de savoir si les formations onomatopéiques représentent un principe primitif de formation des mots, si dans les premières formes du langage humain tous les signes ont été du type craquer, murmurer, etc., dont la plupart auraient ensuite perdu leur charge mimophonique. Saussure s’est prononcé contre toute théorie positive de la signification dans le domaine des sciences du langage, position qui a constitué pour longtemps une norme de travail en linguistique. Cet article traite des icônes auditives dans le lexique hébraïque de la Bible dont l’analogie phonation–référent est rendue manifest…
