Topical capsaicin application and axon reflex vasodilatation of the tongue: Neurogenic involvement in burning mouth syndrome.
2006
The aim of this study was to evaluate the effects of topical capsaicin application on human lingual mucosa and to assess if neurogenic inflammation might have a role in the pathogenesis of lingual diseases. Thirty patients (16 males and 14 females; mean age: 41.46 +/- 11.8 years; range: 23-60) were examined in our laboratory. The neurogenic inflammation was experimentally induced in the lingual mucosa close to 1) the left margin of the tongue and 2) the right margin of the tongue after ipsilateral nerve trunk anesthesia. The characteristics of lingual microcirculation were observed using computerized videocapillaroscopic techniques. The vasodilatation was observed close to the left margin o…
Multidisciplinary learning at the University scientific museums: the Bunsen burner
2017
We report on a laboratory activity carried out together with secondary school (high-school) students, with the aim of increasing their interest toward historical scientific instruments and stimulate their approach to scientific knowledge. To this purpose, we propose a hands-on activity that can be fruitfully performed at the University scientific museums. We organized a one-week summer stage at the Historical Collection of Physics Instruments and at the Museum of Chemistry of the University of Palermo. A group of selected students attended it, under the tutoring of university researchers. They were showed some Bunsen burners belonging to the collections, how they are restored, how they work…
Homework Stress and Learning Disability: The Role of Parental Shame, Guilt, and Need Frustration
2022
Using a cross-sectional design, this study examined the relationships between parental guilt, shame, need frustration, and homework stress in students with learning disabilities (LD) and typically developing students (TD) and their parents. One hundred and eight parent-child dyads (54 LD, 54 TD) completed questionnaires to assess homework stress, parental need frustration, guilt, and shame. Parents of students with LD reported more stress, need frustration, shame, and guilt than parents of TD students. For the LD group, shame mediated the association between parental need frustration and parental and child stress whereas guilt mediated the association between parental need frustration and p…
Hopelessness and burnout in Italian healthcare workers during COVID-19 pandemic: the mediating role of trait emotional intelligence
2023
Objective: The study aims to assess the impact of COVID-19 on healthcare workers’ work-related stress during the first wave of the pandemic in Italy. The main objective is to investigate the existence of a positive correlation between hopelessness and burnout, assuming that burnout may be a riskfactor for the development of hopelessness, and to analyze the role thattrait Emotional Intelligence (TEI) and changes in workload could have in this relationship. Furthermore, evaluate any significant differences in burnoutand hopelessness levels in the function of some demographic variables, such as gender, professional profiles, and different working zones of Italy, tobetter understand how the di…
Latent burnout profiles in a sample of frontline healthcare professionals after the peak of the Italian COVID-19 pandemic
2022
Background: In Italy since February 2020, the unexpected massive afflux of COVID-19 patients exposed healthcare professionals to high work-related stress, high time pressure and increased the risk of being infected. This is the first study that aimed to investigate the psychological impact of COVID-pandemic at the end of the peak, by identifying latent burnout profiles in a sample of front-line healthcare professionals that worked in Italy during the peak of the pandemic. Methods: A total of 589 subjects filled in an online ad-hoc questionnaire and the Italian version of Maslach Burnout Inventory - Human Services Survey. Results: A higher presence of burnout profile in healthcare profession…
Excitonic energy level structure and pigment-protein interactions in the recombinant water-soluble chlorophyll protein. II. Spectral hole-burning exp…
2011
Persistent spectral hole burning at 4.5 K has been used to investigate the excitonic energy level structure and the excited state dynamics of the recombinant class-IIa water-soluble chlorophyll-binding protein (WSCP) from cauliflower. The hole-burned spectra are composed of four main features: (i) a narrow zero-phonon hole (ZPH) at the burn wavelength, (ii) a number of vibrational ZPHs, (iii) a broad low-energy hole at ~665 and ~683 nm for chlorophyll b- and chlorophyll a-WSCP, respectively, and (iv) a second satellite hole at ~658 and ~673 nm for chlorophyll b- and chlorophyll a-WSCP, respectively. The doublet of broad satellite holes is assigned to an excitonically coupled chlorophyll dim…
Introduzione a: FUOCO E CARBONE : le tradizioni dei carbonai
2022
L'introduzione al volume: Fuoco e carbone. Le tradizioni dei carbonai sottolinea un’accorta indagine sul lavoro dei carbonai sardi, sulle fasi di produzione del carbone, sull’influenza che hanno avuto le maestranze toscane nel trasferimento di competenze e abilità sui carbonai locali, sul rapporto uomo-mondo vegetale che trovava massima espressione nel “processo di personificazione” della carbonaia con l’attribuzione di nomi e appellativi. Lo studio indaga, inoltre, le prime attestazioni di utilizzo del fuoco da parte degli uomini e gli impieghi ergologici e sociali che proprio il fuoco ha assunto nel tempo, la sua dimensione simbolica, quella linguistica, l’universo eterogeneo di pratiche …
Acoustic spectral hole-burning in a two-level system ensemble
2020
AbstractMicroscopic two-level system (TLS) defects at dielectric surfaces and interfaces are among the dominant sources of loss in superconducting quantum circuits, and their properties have been extensively probed using superconducting resonators and qubits. We report on spectroscopy of TLSs coupling to the strain field in a surface acoustic wave (SAW) resonator. The narrow free spectral range of the resonator allows for two-tone spectroscopy where a strong pump is applied at one resonance, while a weak signal is used to probe a different mode. We map the spectral hole burnt by the pump tone as a function of frequency and extract parameters of the TLS ensemble. Our results suggest that det…
Nature of the non-exponential primary relaxation in structural glass-formers probed by dynamically selective experiments
1998
Several experimental methods feature the potential to distinguish between slow and fast contributions to the non-exponential, ensemble averaged primary response in glass-forming materials. Some of these techniques are based on the selection of subensembles using multi-dimensional nuclear magnetic resonance, optical bleaching, and non-resonant spectral hole burning. Others, such as the time-dependent solvation spectroscopy, measure microscopic responses induced by local perturbations. Using several of these methods it could be demonstrated for various glass-forming materials that the non-exponential relaxation results from a superposition of dynamically distinguishable entities. The experime…
Neurotic generation of Covid-19 in Eastern Europe
2021
This article presents the results of a research survey, which shows the relationship between neuroticism and the coronavirus pandemic, which was performed among students in Poland and Ukraine. The survey was conducted online, on a sample of 1,978 respondents in Poland and 411 in Ukraine. The results indicated that average and high levels of neuroticism were observed among 61% of respondents in Poland and 47% in Ukraine. Regression analysis revealed that the main factors correlated with the level of neuroticism were educational burnout, gender, financial situation, interest in the pandemic, and satisfaction with life. As indicated by the respondents, neuroticism increases with educational bu…
