Infertility-related stress, anxiety and ovarian stimulation: can couples be reassured about the effects of psychological factors on biological respon…

2016

Abstract The aim of this prospective, longitudinal study was to examine the association between couples' pre-treatment psychological characteristics (state anxiety and infertility-related stress levels of both partners) and ovarian response during assisted reproductive technology treatment in a well-controlled sample. A total of 217 heterosexual couples (434 patients), suffering from primary infertility and undergoing their first assisted reproductive technology treatment at the Reproductive Medicine Unit of ANDROS Day Surgery Clinic in Palermo (Italy), were recruited. Psychological variables were assessed using the State Scale of State-Trait Anxiety Inventory (STAI-S) and the Fertility Pro…

Vínculos transnacionales entre México y Estados Unidos : la figura de José U. Calderón en la transición al cine sonoro /Transnational links between M…

2017

Resumen: Proponemos indagar un aspecto de la cinematografía mexicana que ha tenido poca difusión en la historiografía sobre el cine de ese país: las actividades realizadas por el empresario mexicano José U. Calderón en relación a sus conexiones con Estados Unidos, en pos de las experimentaciones que signaron al período inicial del cine sonoro, que incluyeron la expansión de los cines nacionales tanto internamente como en el mercado exterior por medio de la distribución y exhibición de films. Para ello, se desglosarán diferentes aspectos que Calderón ha logrado desarrollar dando como resultado una expansión de la cinematografía mexicana de características transnacionales, como la experimenta…

Orxata Sound System. Música glocal, libre, colectiva y cooperativa / Orxata Sound System. Glocal, free, collective and cooperative music

2017

Resumen: Orxata Sound System es un colectivo musical de la comarca de l’Horta (País Valenciano) que se fundó el año 2003 y que se disolvió indefinidamente el año 2014. Su existencia ha dejado huella en la escena musical del ámbito catalanófono, no solamente por su estilo, sino también porque fueron pioneros en el uso de las nuevas tecnologías tanto para crear, producir y difundir su música como para (auto)gestionarse y comunicarse con el público de manera eminentemente horizontal. Este artículo observará la trayectoria musical de Orxata Sound System haciendo especial hincapié, por un lado, en la explotación artística que desarrollaron a partir de la hibridación de dos elementos aparentement…

Evidence of the origin of specific spontaneous head turns during intertrial intervals.

1997

Direction and the frequency of spontaneous head movements during the ITIs following forward and backward paired trials were compared to an acquisition of a conditioned orienting (alpha) response directed to the side of the tone source. The head movements were analyzed from video recordings using classification of head turns to preferred and to nonpreferred directions. The results showed a significant increase in the alpha responses during the forward paired conditioning to the preferred direction and rapid extinction during the subsequent backward conditioning sessions. Spontaneous head movements during the ITIs increased to the same preferred direction as the conditioned alpha responses. T…

Virtual Acoustic Rendering in Old Spaces: Application to an Early-Modern Theatre in València, “L’Olivera”

2018

The application of the VR to the renderization of ancient and lost buildings is one important topic in the cultural heritage field nowadays. Moreover, the addition of other senses apart from the graphical view, increases the sensation of immersion in a virtual application. The aim of this paper is to show the work on a virtual acoustic system, based on Unity, FMOD and Csound. This system has been implemented to render binaural auralizations and has been applied to the renderization of an old and lost theatre in Valencia (Spain). This theatre was firstly build in the 16th century, and rebuilt several times until the 18th century. It has been modelled from ancient documents. The auralization …

Lovastatin causes sensitization of HeLa cells to ionizing radiation‐induced apoptosis by the abrogation of G2 blockage

2003

To investigate the effect of inhibition of Ras/Rho-regulated signalling by 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) on radiation-induced cell killing and apoptosis.Different human cell lines were pretreated or not with lovastatin before exposure to gamma-rays. Afterwards, radiation-induced cell killing, formation and repair of double-strand breaks, activation of radiation-inducible signal mechanisms (i.e. p53, p21, extracellular-signal-related kinase (ERK), NF-kappaB), changes in cell cycle progression and apoptosis were analysed.As shown by a colony formation assay, lovastatin sensitized HeLa cells to gamma-radiation-induced cell killing. The lovastati…

Exploring Frequency-Dependent Brain Networks from Ongoing EEG Using Spatial ICA During Music Listening

2020

Recently, exploring brain activity based on functional networks during naturalistic stimuli especially music and video represents an attractive challenge because of the low signal-to-noise ratio in collected brain data. Although most efforts focusing on exploring the listening brain have been made through functional magnetic resonance imaging (fMRI), sensor-level electro- or magnetoencephalography (EEG/MEG) technique, little is known about how neural rhythms are involved in the brain network activity under naturalistic stimuli. This study exploited cortical oscillations through analysis of ongoing EEG and musical feature during freely listening to music. We used a data-driven method that co…

The 15 March 2007 explosive crisis at Stromboli Volcano, Italy: assessing physical parameters through a multidisciplinary approach

2011

Basaltic volcanoes are dominated by lava emission and mild explosive activity. Nevertheless, many basaltic systems exhibit, from time to time, poorly documented and little-understood violent explosions. A short-lived, multiblast explosive crisis (paroxysmal explosion) occurred on 15 March 2007 during an effusive eruptive crisis at Stromboli (Italy). The explosive crisis, which started at 20:38:14 UT, had a total duration of ∼5 min. The combined use of multiparametric data collected by the permanent instrumental networks (seismic, acoustic, and thermal records) and a field survey carried out immediately after the event enabled us to constrain the eruptive dynamics and quantify physical param…

Contactless magnetic excitation of acoustic cavitation in liquid metals

2015

A steady axial magnetic field is applied to a liquid metal zone heated by induction currents. The resulting alternating Lorentz force causes pressure oscillations that being strong enough lead to cavitation in the molten metal. Amplitude of the pressure oscillations is proportional to the product of the induced currents and the steady axial magnetic field induction. We follow an approach where the acoustic pressure is maximized by the induction currents. The onset of cavitation is identified by the occurrence of sub-harmonics of the drive frequency in sound recorded at the surface of the experimental cell. It is demonstrated that cavitation in a liquid metal may be excited by a superimposed…
