Variazione della pressione sistolica e diastolica con la respirazione
2016
L’attività di ricerca in corso riguarda la possibilità di ricavare dati clinicamente significativi dai segnali ottici PPG (PhotoPletysmoGraphy). Il segnale PPG viene utilizzato per ricavare informazioni sul volume e sulla saturazione del sangue che interessa il distretto illuminato dalla luce IR (infrarosso) usata per l’analisi. Il volume di sangue contenuto nel segmento di arteria esaminato dipende dalla pressione e dal ciclo cardiaco, attraverso la rigidità dell’arteria.

Numerical and Experimental Study of a Novel Concept for Hydraulically Controlled Negative Loads
2016
This paper presents a numerical and experimental investigation of a novel concept that eliminates oscillations in hydraulic systems containing a counterbalance valve in series with a pressure compensated flow supply. The concept utilizes a secondary circuit where a low-pass filtered value of the load pressure is generated and fed back to the compensator of the flow supply valve. The novel concept has been implemented on a single boom actuated by a cylinder. A nonlinear model of the system has been developed and an experimental verification shows good correspondence between the model and the real system. The model is used for a parameter study on the novel concept. From the study it is found…
Sigh in patients with acute hypoxemic respiratory failure and acute respiratory distress syndrome: the PROTECTION pilot randomized clinical trial
2021
Background: Sigh is a cyclic brief recruitment manoeuvre: previous physiological studies showed that its use could be an interesting addition to pressure support ventilation to improve lung elastance, decrease regional heterogeneity and increase release of surfactant. Research question: Is the clinical application of sigh during pressure support ventilation (PSV) feasible? Study design and methods: We conducted a multi-center non-inferiority randomized clinical trial on adult intubated patients with acute hypoxemic respiratory failure or acute respiratory distress syndrome undergoing PSV. Patients were randomized to the No Sigh group and treated by PSV alone, or to the Sigh group, treated b…

Rhéologie et déformation du verre dans des conditions extrêmes
2018
Hardness measurements performed at room temperature have proven that glass can flow under elevated pressure. During industrial glass production processes, the actual distribution of stress components in the glass during scribing remains, to date, poorly quantified, and thus continues to be challenging to model numerically. To better quantify the viscous contribution to the rheology of glass, the effect of pressure on the viscosity and structural relaxation of glass, needs to be quantified experimentally by in situ deformation measurements.In this thesis, I performed experiments and models to study: (i) the volumetric relaxation of glass after high-pressure treatment above the glass transiti…
Adrb3 adrenergic receptor is a key regulator of human myometrial apoptosis and inflammation during chorioamnionitis1
2008
The pathophysiology underlying preterm labor triggered by inflammatory conditions such as chorioamnionitis remains largely unclear. It has already been suggested that beta-3 adrenergic (ADRB3) agonists might be of interest in the pharmacological management of preterm labor. Although there is evidence implicating ADRB receptors in the control of inflammation, there are minimal data relating specifically to ADRB3. To explore the cellular consequences of chorioamnionitis and detect apoptosis, we first performed immunostaining and Western blot experiments on human myometrial samples obtained from women with confirmed chorioamnionitis. We then developed an in vitro model of chorioamnionitis by i…
The Occurrence of Diseases and Related Factors in a Center for Asylum Seekers in Italy
2016
Italy is the main recipient of asylum seekers in the European region, and Sicily is their first point of arrival. This geographical position creates a large job for Health Authorities to identify and deal with the health of immigrants. This study evaluates the prevalence of disease among asylum seekers, assessing which are associated factors.A cross-sectional study was conducted to analyse demographic and clinical data in an Acceptance Centres for Asylum Seekers from February 2012 to May 2013. All variables that were found to be significant on unvariable analysis for the most frequent pathologies were included in a multivariable logistic regression model.Post-traumatic stress disorders with…

The Clock'N Test as a Possible Measure of Emotions: Normative Data Collected on a Non-clinical Population.
2016
International audience; Objective: At present emotional experience and implicit emotion regulation (IER) abilities are mainly assessed though self -reports, which are subjected to several biases. The aim of the present studies was to validate the Clock'N test, a recently developed time estimation task employing emotional priming to assess implicitly emotional reactivity and IER. Methods: In Study 1, the Clock' N test was administered to 150 healthy participants with different age, laterality and gender, in order to ascertain whether these factors affected the test results. In phase 1 participant were asked to judge the duration of seven sounds. In phase 2, before judging the duration of the…
