Auditory‐evoked potentials to changes in sound duration in urethane‐anaesthetized mice

2019

Spectrotemporally complex sounds carry important information for acoustic communication. Among the important features of these sounds is the temporal duration. An event-related potential called mismatch negativity indexes auditory change detection in humans. An analogous response (mismatch response) has been found to duration changes in speech sounds in rats but not yet in mice. We addressed whether mice show this response, and, if elicited, whether this response is functionally analogous to mismatch negativity or whether adaptation-based models suffice to explain them. Auditory-evoked potentials were epidurally recorded above the mice auditory cortex. The differential response to the chang…

Trattamento endodontico di un incisivo centrale calcificato

2011

RiassuntoObiettiviDescrivere il trattamento endodontico di un incisivo centrale con due canali e caratterizzato da estese calcificazioni, mostrando come sia possibile affrontare e come possa essere complicato reperire un’anatomia complessa e senza riferimenti.Materiali e metodiTalvolta un radiogramma non è sufficiente a indirizzarci verso la soluzione di casi complessi, perché anche un’attenta analisi, in caso di estese calcificazioni, può essere insufficiente a interpretare correttamente l’anatomia canalare. È quindi indispensabile verificare clinicamente le condizioni dell’elemento dentale, se possibile avvalendosi di un microscopio che, grazie al forte fattore di ingrandimento, permette …

A Setup for Microscopic Studies of Ultrasounds Effects on Microliters Scale Samples: Analytical, Numerical and Experimental Characterization

2021

International audience; Sonoporation is the process of cell membrane permeabilization, due to exposure to ultrasounds. There is a lack of consensus concerning the mechanisms of sonoporation: Understanding the mechanisms of sonoporation refines the choice of the ultrasonic parameters to be applied on the cells. Cells’ classical exposure systems to ultrasounds have several drawbacks, like the immersion of the cells in large volumes of liquid, the nonhomogeneous acoustic pressure in the large sample, and thus, the necessity for magnetic stirring to somehow homogenize the exposure of the cells. This article reports the development and characterization of a novel system allowing the exposure to …

Matrices of the frequency and similarity of Arabic letters and allographs

2020

Published online: 19 February 2020 Indicators of letter frequency and similarity have long been available for Indo-European languages. They have not only been pivotal in controlling the design of experimental psycholinguistic studies seeking to determine the factors that underlie reading ability and literacy acquisition, but have also been useful for studies examining the more general aspects of human cognition. Despite their importance, however, such indicators are still not available for Modern Standard Arabic (MSA), a language that, by virtue of its orthographic system, presents an invaluable environment for the experimental investigation of visual word processing. This paper presents fo…

Shaping the Urban Soundscape in Spanish Palermo

2018

My research focuses mainly on official music making, that is promoted by the politic and religious power, in Palermo in the age of the Spanish domination. What I discuss in my chapter, is: 1) how music contributed specifically to shape the urban space, 2) which was the relation between musical experience and political power during the Spanish domination. I will focus on the second half of the seventeenth-century, the final years of the Spanish rule. In this period of time, two important events marked the musical shaping of the urban space: 1) in 1682, the creation of a permanent venue for performing music “en plein air”, the so-called “teatro della musica” in the Strata Colonna; 2) in 1693,…

The Androgen Excess and PCOS Society criteria for the polycystic ovary syndrome: the complete task force report.

2009

Abstract OBJECTIVE: To review all available data and recommend a definition for polycystic ovary syndrome (PCOS) based on published peer-reviewed data, whether already in use or not, to guide clinical diagnosis and future research. DESIGN: Literature review and expert consensus. SETTING: Professional society. PATIENTS: None. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): A systematic review of the published peer-reviewed medical literature, by querying MEDLINE databases, to identify studies evaluating the epidemiology or phenotypic aspects of PCOS. RESULT(S): The Task Force drafted the initial report, following a consensus process via electronic communication, which was then reviewed and c…

Early auditory processing in musicians and dancers during a contemporary dance piece

2016

AbstractThe neural responses to simple tones and short sound sequences have been studied extensively. However, in reality the sounds surrounding us are spectrally and temporally complex, dynamic and overlapping. Thus, research using natural sounds is crucial in understanding the operation of the brain in its natural environment. Music is an excellent example of natural stimulation which, in addition to sensory responses, elicits vast cognitive and emotional processes in the brain. Here we show that the preattentive P50 response evoked by rapid increases in timbral brightness during continuous music is enhanced in dancers when compared to musicians and laymen. In dance, fast changes in brigh…

Recurrent wheezing during the first 3 years of life in a birth cohort of moderate-to-late preterm infants.

2019

Background Data addressing short- and long-term respiratory morbidity in moderate-late preterm infants are limited. We aim to determine the incidence of recurrent wheezing and associated risk and protective factors in these infants during the first 3 years of life. Methods Prospective, multicenter birth cohort study of infants born at 32+0 to 35+0 weeks' gestation and followed for 3 years to assess the incidence of physician-diagnosed recurrent wheezing. Allergen sensitization and pulmonary function were also studied. We used multivariate mixed-effects models to identify risk factors associated with recurrent wheezing. Results A total of 977 preterm infants were enrolled. Rates of recurrent…

Maternal complications in pregnancy and wheezing in early childhood: a pooled analysis of 14 birth cohorts

2015

Background: Evidence on the effect of maternal complications in pregnancy on wheezing in offspring is still insufficient. Methods: A pooled analysis was performed on individual participant data from fourteen European birth cohorts to assess the relationship between several maternal pregnancy complications and wheezing symptoms in the offspring. Exposures of interest included hypertension and preeclampsia, diabetes, as well as pre-pregnancy overweight (body mass index between 25 and 29.9) and obesity (body mass index >= 30) compared with normal weight (body mass index between 18.5 and 24.9). Outcomes included both ever and recurrent wheezing from birth up to 12-24 months of age. Cohort-speci…
