D. Dinis del Portogallo e Isabel d'Aragona in vita e in morte. Creazione e trasmissione della memoria nel contesto storico e artistico europeo.

La Tesi è incentrata sulle figure di D. Dinis e Isabel d’Aragona, reali del Portogallo (fine del XIII-prima metà del XIV secolo), e si focalizza sul processo di creazione e trasmissione della memoria, elaborato e messo in atto dai sovrani nel corso della loro esistenza. L’atto finale di questo annoso processo fu la realizzazione dei loro monumenti funebri creati per essere conservati nella chiesa del monastero cistercense di São Bernardo e São Dinis di Odivelas, la tomba del re, e nella chiesa del monastero di Santa Clara e Santa Isabel di Coimbra, quella della regina. Infatti, in modo del tutto inedito rispetto alla tradizione precedente, i re commissionarono e videro in vita realizzati i sepolcri che avrebbero dovuto preservare la loro memoria per l’Eternità. Essi furono concepiti a priori come parte integrante del progetto monumentale più vasto costituito dagli edifici monastici che li avrebbero dovuti custodire. In tale prospettiva, è stata rivolta particolare attenzione alla storia del monastero di Odivelas, assurto a pantheon della Monarchia, seppure per breve tempo, e al monastero di Coimbra, ultima dimora della regina Isabel una volta fallito il progetto del pantheon reale a causa della guerra civile che sconvolse il regno del Portogallo tra il 1319 e il 1324. Oltre ai sepolcri reali, sono state prese in esame alcune opere di architettura e di scultura legate alla committenza regia – in coppia o individualmente –, in particolare tre tombe coeve, due delle quali destinate ad altrettanti membri della famiglia reale. All’interno di questa Tesi, i monumenti funebri esaminati sono stati considerati non solo come strumento privilegiato per la commemorazione del defunto, ma anche come forieri di un preciso messaggio indirizzato a tutti coloro che avrebbero fruito della loro visione. Così, l’iconografia dei sepolcri è stata analizzata alla luce della spiritualità e della religiosità dei sovrani, oltre che dal punto di vista stilistico e formale. Come premessa allo studio prettamente storico-artistico, inizialmente sono stati approfonditi i rapporti tra il regno del Portogallo e la Sede Apostolica al momento dell’ascesa al trono di D. Dinis e, successivamente, il tema della guerra civile che vide contrapporsi il re e il principe, il futuro Alfonso IV. A questo scopo, integra la Tesi un’Appendice documentaria che presenta 64 documenti, la maggior parte dei quali inediti. Questo studio intende dimostrare come il Portogallo dionisino si collochi pienamente nell’orbita culturale mediterranea e proporre nuove affermazioni, considerazioni ed ipotesi rispetto ai re Dinis e Isabel, alle loro vicende storiche e personali e alla memoria di sé che vollero trasmettere ai posteri.

Mosaici parietali d’epoca giustinianea a Ravenna. Nuove scoperte

La fascia superiore dell’arco trionfale di S. Apollinare in Classe è stata accuratamente ispezionata durante l’ultimo intervento di restauro. Questa area musiva, col Cristo benedicente affiancato dai simboli degli Evangelisti, ritenuta omogenea e ascritta da tutti gli studiosi a un momento posteriore al VI secolo, è stata in buona parte ricondotta al periodo giustinianeo. I simboli degli Evangelisti e le nuvole limitrofe sono stati ricondotti ai mosaicisti bizantini attivi nella chiesa di San Vitale; mentre a una lavorazione successiva, determinata dalla necessità di reintegrare parti crollate, si deve attribuire il clipeo del Cristo e le nuvole circostanti. Il confronto fra le differenti morfologie delle nubi, le diverse tecniche esecutive e l’utilizzo di nuovi materiali, costituisce l’aspetto più visibile. Il restauro ha permesso di discriminare con certezza l’eterogeneità delle partiture e la convivenza di due interventi stilisticamente e cronologicamente differenti. Molteplici elementi mostrano come da un’esecuzione accurata si passi a una realizzazione sommaria; come dal rigore formale e materico iniziale, che comporta la selezione dei materiali più pregiati e delle tonalità cromatiche più funzionali, si passi ad una povertà materica e a una limitata gamma cromatica organizzate con semplificazione formale.

Form tutors in the joint teaching of music: perspectives and experiences

In the Portuguese school system, form tutors (FTs) are an intermediate education management structure. The form tutor is responsible for a position of coordination and orientation with a «threefold function»: a relationship with students, relationship with the student’s family and relationship with other class teachers. The joint teaching of music is a part of the educational system in basic education. It is optional and provides musical and instrumental training to students who are interested in taking it. In order to achieve this, there is a system, subject to protocols, between general education schools and schools specializing in teaching music. There is also the position of FT in specialized schools and it also includes a «threefold function». However, these FTs have the additional role of representing music teachers at the class council, which is held at the general education school. Thus, in these cases, both FTs have a fourth joint area, between the music school and the general education school, which makes the relationship between them even more complex. This paper is based on the analysis of empirical data obtained from the testimonies of FTs regarding their representations and experiences in leadership and the coordination of teachers among schools in which there is a joint teaching system. The aim of collecting narratives is to look into some of the main challenges and confrontations related to leadership issues, which we assume to be the focus of those who have the role of form tutor in that specific context.

Repository power: how repositories can support Open Access mandates

Many funding agencies have Open Access mandates in place, but how often are scientific publications as outputs linked to funding details? The benefits of linking funding information to publications as part of the deposit workflow can assist in adhering to Open Access mandates. This paper examines how OpenAIRE – Open Access Infrastructure for Research in Europe – can ease monitoring Open Access and reporting processes for funders, and presents some results and opportunities. It also outlines how it relies on cleaned and curated repository content, a vital cog in the ever turning wheel of the global scholarly landscape, and the benefits it brings.

Albuterol delivery in an in vitro pediatric ventilator lung model: comparison of jet, ultrasonic, and mesh nebulizers.

OBJECTIVE: : To determine the influence of nebulizer types and nebulization modes on bronchodilator delivery in a mechanically ventilated pediatric lung model. DESIGN: : In vitro, laboratory study. SETTING: : Research laboratory of a university hospital. INTERVENTIONS: : Using albuterol as a marker, three nebulizer types (jet nebulizer, ultrasonic nebulizer, and vibrating-mesh nebulizer) were tested in three nebulization modes in a nonhumidified bench model mimicking the ventilatory pattern of a 10-kg infant. The amounts of albuterol deposited on the inspiratory filters (inhaled drug) at the end of the endotracheal tube, on the expiratory filters, and remaining in the nebulizers or in the ventilator circuit were determined. Particle size distribution of the nebulizers was also measured. MEASUREMENTS AND MAIN RESULTS: : The inhaled drug was 2.8% ± 0.5% for the jet nebulizer, 10.5% ± 2.3% for the ultrasonic nebulizer, and 5.4% ± 2.7% for the vibrating-mesh nebulizer in intermittent nebulization during the inspiratory phase (p < 0.01). The most efficient nebulizer was the vibrating-mesh nebulizer in continuous nebulization (13.3% ± 4.6%, p < 0.01). Depending on the nebulizers, a variable but important part of albuterol was observed as remaining in the nebulizers (jet and ultrasonic nebulizers), or being expired or lost in the ventilator circuit (all nebulizers). Only small particles (range 2.39-2.70 µm) reached the end of the endotracheal tube. CONCLUSIONS: : Important differences between nebulizer types and nebulization modes were seen for albuterol deposition at the end of the endotracheal tube in an in vitro pediatric ventilator-lung model. New aerosol devices, such as ultrasonic and vibrating-mesh nebulizers, were more efficient than the jet nebulizer.

Coffee and tea intake and risk of head and neck cancer: pooled analysis in the International Head and Neck Cancer Epidemiology Consortium.

BACKGROUND: Only a few studies have explored the relation between coffee and tea intake and head and neck cancers, with inconsistent results. METHODS: We pooled individual-level data from nine case-control studies of head and neck cancers, including 5,139 cases and 9,028 controls. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (95% CI), adjusting for potential confounders. RESULTS: Caffeinated coffee intake was inversely related with the risk of cancer of the oral cavity and pharynx: the ORs were 0.96 (95% CI, 0.94-0.98) for an increment of 1 cup per day and 0.61 (95% CI, 0.47-0.80) in drinkers of >4 cups per day versus nondrinkers. This latter estimate was consistent for different anatomic sites (OR, 0.46; 95% CI, 0.30-0.71 for oral cavity; OR, 0.58; 95% CI, 0.41-0.82 for oropharynx/hypopharynx; and OR, 0.61; 95% CI, 0.37-1.01 for oral cavity/pharynx not otherwise specified) and across strata of selected covariates. No association of caffeinated coffee drinking was found with laryngeal cancer (OR, 0.96; 95% CI, 0.64-1.45 in drinkers of >4 cups per day versus nondrinkers). Data on decaffeinated coffee were too sparse for detailed analysis, but indicated no increased risk. Tea intake was not associated with head and neck cancer risk (OR, 0.99; 95% CI, 0.89-1.11 for drinkers versus nondrinkers). CONCLUSIONS: This pooled analysis of case-control studies supports the hypothesis of an inverse association between caffeinated coffee drinking and risk of cancer of the oral cavity and pharynx. IMPACT: Given widespread use of coffee and the relatively high incidence and low survival of head and neck cancers, the observed inverse association may have appreciable public health relevance.

Influència de la música italiana en la composició en llengua romanç a la catedral de Tortosa (Tarragona), en la primera m. del segle XVIII

Estudi realitzat a partir d’una estada a la Società Italiana di Musicologia entre abril i maig del 2006. S’ha estudiat la influència de la música italiana durant les primeres dècades del segle XVIII, en les composicions en llengua romanç d’aquesta època conservades a l’arxiu musical de la catedral de Tortosa -Tarragona -. Sha a consultat de bibliografia específica així com la consulta directa de fonts italianes de l’època i l’estudi de les seves característiques (tipus d’escriptura, compasos més freqüents, estructura formal, veus/instruments utilitzats, ...). La consulta s’ha fet a diferents arxius i biblioteques romanes (arxiu històric i biblioteca de la Accademia Nazionale di S. Cecilia, biblioteca del Pontificio Istituto di Musica Sacra, arxiu de la Chiesa del Gesú, arxiu de la Chiesa Nazionale Spagnola, biblioteca del Conservatorio di musica Santa Cecilia i Biblioteca Nazionale Centrale Vittorio Emanuele II), així com de la Biblioteca Apostolica i el Archivio Segreto del Vaticano. La recerca ha confirmat que, durant les primeres dècades del segle XVIII, hi ha una influència considerable de la música italiana “de moda” en les composicions de la catedral de Tortosa escrites en llengua vernacla i, després d’un estudi comparatiu i de l’anàlisi d’una mostra de les obres italianes i de la Seu, s’ha arribat a la conclusió de que, si bé hi ha elements italians en les composicions tortosines, no es perd en elles el llenguatge hispànic de la tradició, si no que més bé hi ha una convivència de tots dos, fins i tot en una mateixa obra.

Methylation profile of TP53 regulatory pathway and mtDNA alterations in breast cancer patients lacking TP53 mutations.

The present study investigated promoter hypermethylation of TP53 regulatory pathways providing a potential link between epigenetic changes and mitochondrial DNA (mtDNA) alterations in breast cancer patients lacking a TP53 mutation. The possibility of using the cancer-specific alterations in serum samples as a blood-based test was also explored. Triple-matched samples (cancerous tissues, matched adjacent normal tissues and serum samples) from breast cancer patients were screened for TP53 mutations, and the promoter methylation profile of P14(ARF), MDM2, TP53 and PTEN genes was analyzed as well as mtDNA alterations, including D-loop mutations and mtDNA content. In the studied cohort, no mutation was found in TP53 (DNA-binding domain). Comparison of P14(ARF) and PTEN methylation patterns showed significant hypermethylation levels in tumor tissues (P < 0.05 and <0.01, respectively) whereas the TP53 tumor suppressor gene was not hypermethylated (P < 0.511). The proportion of PTEN methylation was significantly higher in serum than in the normal tissues and it has a significant correlation to tumor tissues (P < 0.05). mtDNA analysis revealed 36.36% somatic and 90.91% germline mutations in the D-loop region and also significant mtDNA depletion in tumor tissues (P < 0.01). In addition, the mtDNA content in matched serum was significantly lower than in the normal tissues (P < 0.05). These data can provide an insight into the management of a therapeutic approach based on the reversal of epigenetic silencing of the crucial genes involved in regulatory pathways of the tumor suppressor TP53. Additionally, release of significant aberrant methylated PTEN in matched serum samples might represent a promising biomarker for breast cancer.

Body mass index, cigarette smoking, and alcohol consumption and cancers of the oral cavity, pharynx, and larynx: modeling odds ratios in pooled case-control data.

Odds ratios for head and neck cancer increase with greater cigarette and alcohol use and lower body mass index (BMI; weight (kg)/height(2) (m(2))). Using data from the International Head and Neck Cancer Epidemiology Consortium, the authors conducted a formal analysis of BMI as a modifier of smoking- and alcohol-related effects. Analysis of never and current smokers included 6,333 cases, while analysis of never drinkers and consumers of < or =10 drinks/day included 8,452 cases. There were 8,000 or more controls, depending on the analysis. Odds ratios for all sites increased with lower BMI, greater smoking, and greater drinking. In polytomous regression, odds ratios for BMI (P = 0.65), smoking (P = 0.52), and drinking (P = 0.73) were homogeneous for oral cavity and pharyngeal cancers. Odds ratios for BMI and drinking were greater for oral cavity/pharyngeal cancer (P < 0.01), while smoking odds ratios were greater for laryngeal cancer (P < 0.01). Lower BMI enhanced smoking- and drinking-related odds ratios for oral cavity/pharyngeal cancer (P < 0.01), while BMI did not modify smoking and drinking odds ratios for laryngeal cancer. The increased odds ratios for all sites with low BMI may suggest related carcinogenic mechanisms; however, BMI modification of smoking and drinking odds ratios for cancer of the oral cavity/pharynx but not larynx cancer suggests additional factors specific to oral cavity/pharynx cancer.
