Il salto sillabico. Dalle ottave del Meli al cunto di Mimmo Cuticchio
2019
Nei versi vernacolari del Meli ritroviamo la combinazione sillabica che possiamo definire salto sillabico o cambio di voce, perché impone nella declamazione un mutamento del grado e del tono della voce. Il cambio di voce o salto nel Meli si forma dalla mescolanza di sillabe di differente modalità, articolazione e grado, caratterizza il suono del verso e costruisce la variante tonale; nella quale si enuclea l’interpretazione del tema; inoltre il salto viene sottolineato con decisione grazie all’accostamento dei differenti gradi dell’articolazione delle sillabe. In alcune canzuni del Meli il salto cosiddetto sillabico affiora in presenza della mescolanza delle sillabe continue con quelle occl…
'Ignosce, non possum'. Modelli declamatori e topoi tragici a confronto: padri e figli tra declamazione e tragedia
2013
This paper deals with the links between Latin declamation and tragedy through the investigation of some controversiae, focusing on the relationship father-son. The comparison between some declamatories passages (Sen. contr. 1, 4 and Calp. exc. 18) and some Senecan tragic verses (from Thyestes and Phaedra) allows to detect the proximity between the rhetoric practiced in the schools of declamation and Senecan tragic theatre.

Bis(terpyridyl)-ruthenium(II) units attached to polyazacycloalkanes as sensing fluorescent receptors for transition metal ions
2000
A synthetic strategy has been devised for the preparation of new compounds in which terpyridyl fragments are linked to 1,4,8,11-tetraazacyclotetradecane (cyclam). Reaction of excess cyclam with 4′-[(4-bromomethyl)phenyl]-2,2′:2″,6′-terpyridine afforded the ligand 1-[4′-p-tolyl-(2,2′:6′,2″-terpyridyl)]-1,4,8,11-tetraazacyclotetradecane (L1) in which the tetraaza macrocycle was covalently attached to one benzyl-terpyridyl fragment. Under similar conditions reaction of cyclam with excess 4′-[(4-bromomethyl)phenyl]-2,2′:2″,6′-terpyridine gave the tetra substituted cyclam derivative 1,4,8,11-[4′-p-tolyl-(2,2′:6′,2″-terpyridyl)]-1,4,8,11-tetraazacyclotetradecane (L2). The multidentate ligand L2 w…
[Ni(cyclam)(μ1,3-dca)2Cu(μ1,5-dca)2]: A Genuine 3D Bimetallic Coordination Polymer Containing Both μ1,3- and μ1,5-Bidentate Dicyanamide Bridges and …
2005
The structure of [Ni(cyclam)(μ 1 , 3 -dca) 2 Cu(μ 1 , 5 -dca) 2 ], a genuine 3D dicyanamide-bridged bimetallic coordination polymer, is made up of 2D [Cu(μ- 1 , 5 dca) 2 ] n layers connected by [Ni(cyclam)(μ 1 , 3 -dca) 2 ] bridging moieties; it exhibits a ferromagnetic exchange interaction between copper(ll) and nickel(ll) ions through the μ 1 , 3 -bidentate dicyanamide bridges.
Mechanical and electrophysiological effects of cromakalim on the human urinary bladder.
1994
The effects of cromakalim on spontaneous and induced mechanical activity of human detrusor muscle were investigated in vitro. Cromakalim produces a concentration-related decrease of spontaneous as well as carbachol- and K(+)-evoked contractions. This is the first study to utilize the patch clamp technique to elucidate the mechanism of action of cromakalim on human detrusor cells. Cromakalim hyperpolarizes the detrusor cells by increasing the net outward current which is most likely carried by potassium ions. In the human urinary bladder, this effect is mediated by a glibenclamide-sensitive potassium channel, as glibenclamide is able to diminish the relaxant effect of cromakalim and to preve…
Extracellular site of action of phenylalkylamines on L-type calcium current in rat ventricular myocytes.
1995
The effects of the phenylalkylamines verapamil, gallopamil, and devapamil on L-type calcium currents (ICa) were studied in ventricular myocytes from rat hearts using the whole-cell patch-clamp technique. In particular, the question was addressed, whether the pharmacological binding sites for these drugs were located at the inner and/or at the outer surface of the cell membrane. Therefore, tertiary verapamil, gallopamil, and devapamil and their corresponding quaternary derivatives were applied either from the outside or the inside of the cell membrane. Extracellular application of verapamil, gallopamil and devapamil (each at 3 microM) reduced ICa to 16.1 +/- 8.6%, 11 +/- 8.9%, and 9.3 +/- 6%…
Functional Integration of Neuronal Precursors in the Adult Murine Piriform Cortex
2018
Abstract The extent of functional maturation and integration of nonproliferative neuronal precursors, becoming neurons in the adult murine piriform cortex, is largely unexplored. We thus questioned whether precursors eventually become equivalent to neighboring principal neurons or whether they represent a novel functional network element. Adult brain neuronal precursors and immature neurons (complex cells) were labeled in transgenic mice (DCX-DsRed and DCX-CreERT2 /flox-EGFP), and their cell fate was characterized with patch clamp experiments and morphometric analysis of axon initial segments. Young (DCX+) complex cells in the piriform cortex of 2- to 4-month-old mice received sparse synapt…
Crónica de la jurisprudencia del Comité Europeo de Derechos Sociales - 2020
2021
La presente crónica aborda un año crucial (2020) en el que la actividad del Comité Europeo de Derechos Sociales se ha enfrentado a la grave crisis provocada por la pandemia de la Covid-19. En este sentido, la jurisprudencia del Comité sobre el sistema de informes se ha centrado en un grupo temático particularmente afectado por dicha crisis (¿Empleo, formación e igualdad de oportunidades¿). Por otro lado, la jurisprudencia del Comité sobre el procedimiento de reclamaciones colectivas se ha visto especialmente reforzada, con ocasión de la resolución de quince importantes reclamaciones, por los nuevos perfiles en materia de lucha contra la brecha salarial de género y la representación de las m…
