Noninvasive Ph-telemetric Measurement of Gastrointestinal Function

The purpose of this study was to gain experience with and validate the Heidelberg pH-telemetric methodology in order to determine if the pH-telemetric methodology would be a useful noninvasive measure of gastrointestinal transit time for future ground-based and in-flight drug evaluation studies. The Heidelberg pH metering system is a noninvasive, nonradioactive telemetric system that, following oral ingestion, continuously measures intraluminal pH of the stomach, duodenum, small bowel, ileocecal junction, and large bowel. Gastrointestinal motility profiles were obtained in normal volunteers using the lactulose breath-hydrogen and Heidelberg pH metering techniques. All profiles were obtained in the morning after an overnight fast. Heidelberg pH profiles were obtained in the fasting and fed states; lactulose breath-hydrogen profiles were obtained after a standard breakfast. Mouth-to-cecum transit time was measured as the interval from administration of lactulose (30 ml; 20 g) to a sustained increase in breath-hydrogen of 10 ppm or more. Gastric emptying time was measured as the interval from the administration of the Heidelberg capsule to a sustained increase in pH of three units or more

Comparing the TiOblast and Osseospeed surfaces. Histomorphometric and histological analysis in humans

The aim of the present study was to compare two implant surfaces, the TiOblast (Astra Tech) surface, manufactured by blasting the surface and already present in literature and the Osseospeed (Astra Tech) surface, manufactured by blasting and treating the surface with fluoride ions and recently launched onto the market with the modified surfaces of the latest generation. This study is part of a more extensive research project whose protocol required the insertion of 10 couples of implants; thus in the present discussion partial data are being taken into consideration, with an eye at collecting more data in the future, regarding both microscopy and histomorphometric histological analysis on 5 couples of implants. The purpose of the study is to investigate how the modified surfaces of the latest generation can guarantee a greater osseointegration both from a qualitative and quantitative level compared to the surfaces presently used and that they may represent the first example of "bioactivity", that is, an active interaction with the processes of new bone formation and tissue healing

Analisi della "futurità" verbale in ottica comparativa italiana-francese-inglese

Questo contributo, che prende spunto da una recente Tesi di Dottorato, concerne lo studio di alcune espressioni verbali della “futurità” verbale in tre lingue indoeuropee – il francese, l'italiano e l'inglese. In particolare, ci si focalizzerà su un’analisi delle forme verbali più diffuse ed attestate per la manifestazione della nozione di “futurità”, cioè il futuro semplice ed anteriore – francese e italiano – will/shall semplice, composto e contratto – inglese – ma anche tutta una serie di perifrasi definite “futuri perifrastici”. Il lavoro è condotto attraverso la considerazione di un corpus trilingue, raccolto a partire dalla sezione dell’economia di tre quotidiani – Le Figaro, Corriere della sera, The Times – in un lasso temporale di due mesi (1° gennaio 20007 – 28 febbraio 2007). L’indagine, coadiuvata dall’inserimento dei dati all’interno del software AntConc3.2.1, consiste in uno spoglio dapprima quantitativo, poi qualitativo, dei dati, con osservazioni di carattere comparativo e contrastivo,. Ci si propone anzitutto di mettere in evidenza le relazioni esistenti tra gli indici della “futurità” rilevati e il discorso di divulgazione economica, in modo da reperire la proporzione e la funzione svolta dalle forme verbali trattate, nonché il ruolo rivestito dalla “futurità” nell’ambito del discorso di divulgazione economica della stampa non specializzata
