Postnatal weight growth and trihalomethane exposure during pregnancy.
2014
Abstract Background Impaired postnatal growth after chloroform exposure in utero has been observed in rodents without an effect on birth weight. We aimed to study the relationship between exposure to trihalomethanes (THMs) during pregnancy and postnatal weight growth during infancy. Methods We analysed 2216 mother–child pairs recruited in Gipuzkoa, Sabadell, Valencia (Spain, INMA Project, enrolment: 2003–2008) and Crete (Greece, RHEA Study, enrolment: 2007–2008). Drinking water habits and water-related activities ascertained through personal interviews were combined with THM measurements in drinking water to estimate THM exposure through different exposure routes during pregnancy. Weight me…
The influence of active secretion processes on intestinal absorption of salbutamol in the rat.
2001
Abstract Salbutamol was perfused in the small intestine of rat using a standard rat gut ‘in situ’ preparation: (1) in inhibitor-free solution at seven different concentrations (0.15, 0.29, 1.20, 5.0, 9.0, 13.0 and 18.0 mM); (2) at a 0.29 mM concentration – thought to be close to the allometric dose in man – in the presence of a non-specific enzyme inhibitor, sodium azide (0.3, 3.0 and 6.0 mM); and (3) at 0.29 mM in the presence of a selective secretion inhibitor, verapamil (10.0 and 20.0 mM). In free solution, the mixed-order rate constants, k ′ a , of salbutamol increase as the solute concentration increases until an apparent asymptotic value is reached. This could be due to the saturation…
Nitric oxide-mediated beta 2-adrenoceptor relaxation is impaired in mesenteric veins from portal-hypertensive rats.
1996
Abstract BACKGROUND & AIMS: beta-Adrenergic relaxation seems to be mediated by nitric oxide. The aim of this study was to evaluate changes induced by portal hypertension in beta 2-adrenergic vasorelaxation. METHODS: Isolated rat mesenteric veins were relaxed by salbutamol, and nerve- mediated vasocontractions were induced by electrical field stimulation. Responses were evaluated in the presence of NG-nitro-L-arginine methyl ester (L-NAME) or tetrodotoxin. Immunocytochemical techniques were used for localization of neuronal NO synthase. RESULTS: Salbutamol-induced relaxations were decreased in rings from portal-hypertensive animals. L- NAME reduced these relaxations, but its effects were mor…
New insights in respiratory impedance in young children after repair of congenital diaphragmatic hernia: a cross-sectional study
2019
Abstract Lung function impairment is common in Congenital Diaphragmatic Hernia (CDH) survivors. The aim of this study was to evaluate, in children who underwent CDH surgical repair, mid and long-term consequences on respiratory impedance, investigating the impact of CDH on both resistance and reactance parameters, as well as bronchodilator response. Forced Oscillation Technique (FOT) parameters were collected from 12 patients (2–11 years). Resistance and reactance values at 8 Hz (Rrs8, Xrs8) and the area under the reactance curve (AX) were measured pre and post-salbutamol. Quantitative variables were compared using Mann-Whitney U test. Differences of categorical variables were evaluated usi…
La libertà tra determinismo naturale e determinismo teologico: Il De servo arbitrio di Lutero
2018
L'articolo analizza il rapporto tra determinismo naturale e storico da un lato e determinismo teologico dall'altro, così come Lutero lo affronta nel De servo arbitrio, a partire dalla sua concreta esperienza di fede. L'articolo cerca di mostrare come l'idea di determinismo di Lutero sia escludente l’opposta idea d’indeterminazione, ragion per cui egli rifiuta la concezione della libertà come libertas indifferentiae, ma non la contingenza degli eventi e quindi neppure l'autodeterminazione dell'uomo. Nell'articolo si mostra come la posizione di Lutero al riguardo sia stata accolta da Leibniz e da Hegel. The article analyzes the relationship between natural and historical determinism on the on…
Le metamorfosi del corale "Vom Himmel hoch da komm ich her" fra Lutero, Bach e Stravinsky
2020
Il corale matalizio "Vom Himmel hoch da komm ich her" (Dall'alto dei cieli io giungo) è stato realizzato da Martin Lutero sulla base della melodia popolare "Ich komm aus fremden Landen her" e fu pubblicato per la prima volta a Wittenberg nel 1535. Assai diffuso in tutta l'area culturale tedesca, questo brano è stato ripreso, tra gli altri, anche da J.S. Bach, sia nel "Weinachts-Oratorium" BWV 248 che nelle "Canonische Veraenderungen" per organo BWV 796 e 796a. Il saggio ricostruisce il contesto in cui vide la luce la versione originale del canto natalizio e si sofferma sull'interesse di Bach per la numerologia e sulle "citazioni nascoste" in molte sue opere, incluse le "Veraenderungen" sul …

Musica e architettura. Le opere di Igor Stravinsky per la basilica di San Marco a Venezia
2019
Il 13 settembre 1956, Stravinsky diresse nella basilica di San Marco a Venezia la prima esecuzione del "Canticum Sacrum" (1955), insieme con le "Variazioni-corali sulla canto natalizio Vom Himmel hoch…" (1955-56). Il "Canticum" era stato realizzato su commissione del Festival delle Biennale e costituisce un esempio dell'approccio del compositore alla tecnica dodecafonica. Le "Variazioni-corali" presentano quasi il medesimo organico del "Canticum" e sono invece da considerarsi come una sorta di ripensamento creativo delle "Variazioni canoniche" BWV 796-796a di Johann Sebastian Bach. September 13th 1956, Stravinsky conducted at the basilica of St. Mark in Venice the first performance of the "…
Influence of mechanical activation on the physical stability of salbutamol sulphate.
2003
Abstract In order to obtain the optimal particle size distribution for pharmaceutical powders in dry powder inhalers the particles have to be micronised. In most cases the process of micronisation is connected with a high input of energy which induces disorder and defects on the surface of the drug particles and as a result changes in the crystallinity. Consequently, changes in the physical stability of the powders may occur. To investigate changes on the physical stability of the powder, different analytical methods are used in the present investigation: laser diffraction, Differential Scanning Calorimetry (DSC), isothermal microcalorimetry and DVS-method. Air-jet-milling is one of the mos…
