Laterolateral teleradiography of the skull as a screening method for OSA/OSAS, in patients in orthodontic treatment
2019
Aim: Obstructive sleep apnea syndrome (OSAS) is the most common type of sleep apnea and it is caused by complete or partial obstruction of the upper airway. Adenotonsillar hypertrophy, obesity, cranio-facial anomalies and neuromuscular diseases are the main risk factors for the development of OSAS in the pediatric age. Specially several studies identify the relationship between respiratory disorders in sleep and obesity, and, in particular, between OSAS and obesity, designing a prevalence of OSAS among obese subjects between 14 and 78%. The diagnosis of OSAS in the child is of great importance as it can lead to neurocognitive and behavioral complications, growth retardation, systemic arteri…
Static and non-static vector screening masses
2016
Thermal screening masses of the conserved vector current are calculated both in a weak-coupling approach and in lattice QCD. The inverse of a screening mass can be understood as the length scale over which an external electric field is screened in a QCD medium. The comparison of screening masses both in the zero and non-zero Matsubara frequency sectors shows good agreement of the perturbative and the lattice results. Moreover, at $T\approx 508\mathrm{MeV}$ the lightest screening mass lies above the free result ($2\pi T$), in agreement with the $\mathcal{O}(g^2)$ weak-coupling prediction.
Molecular dynamics, dynamic site mapping, and highthroughput virtual screening on leptin and the Ob receptor as anti-obesity target.
2014
Body weight control is a mechanism finely regulated by several hormonal, metabolic, and nervous pathways. The leptin receptor (Ob-R) is crucial for energy homeostasis and regulation of food uptake. Leptin is a 16 kDa hormone that is mainly secreted by fat cells into the bloodstream, and under normal circumstances, circulating levels are proportionate to the fat body mass. Sensing of elevated leptin levels by the hypothalamic neurocircutry activates a negative feedback loop resulting in reduced food intake and increased energy expenditure. Decreased concentrations lead to opposite effects. Therefore rational design of leptin agonists constitute an appealing challenge in the battle against ob…
Cytotoxicity of Endoperoxides from the Caribbean Sponge Plakortis halichondrioides towards Sensitive and Multidrug-Resistant Leukemia Cells: Acids vs…
2016
The 6-epimer of the plakortide H acid (1), along with the endoperoxides plakortide E (2), plakortin (3), and dihydroplakortin (4) have been isolated from a sample of the Caribbean sponge Plakortis halichondrioides. To perform a comparative study on the cytotoxicity towards the drug-sensitive leukemia CCRF-CEM cell line and its multi-drug resistant subline CEM/ADR5000, the acid of plakortin, namely plakortic acid (5), as well as the esters plakortide E methyl ester (6) and 6-epi-plakortide H (7) were synthesized by hydrolysis and Steglich esterification, respectively. The data obtained showed that the acids (1, 2, 5) exhibited potent cytotoxicity towards both cell lines, whereas the esters s…
Efficacy of screen recording in the other-revision of translations: episodic memory and event models
2014
In a 2011 study, Angelone compared the self-revision results of graduate German translation students. Participants documented their original translations using Integrated Problem and Decision Reporting (IPDR) logs (Gile 2004), think-aloud protocols and screen recordings. They then used this documentation to assist self-revision of their translations. Angelone found a significant improvement in error detection overall and in each of six discrete error categories when participants used screen recordings to assist their self-revision. We sought to partially replicate Angelone’s findings concerning the efficacy of screen recording in translation revision. Instead of focusing on self-revision, w…
The video game experience as 'true' identification: A theory of enjoyable alterations of players' self-perception
2009
This article introduces an explication of video game players' identification with a game character or role that is based on social-psychological models of self-perception. Contrasting with conventional ("dyadic" ) notions of media user-character relationships (e.g., parasocial interaction or affective disposition theory), ("monadic" ) video game identification is defined as a temporal shift of players' self-perception through adoption of valued properties of the game character. Implications for media enjoyment, the measurement of identification, and media effects are discussed. © 2009 International Communication Association.

Characterisation of the essential oil of Nepeta glomerata Montbret et Aucher ex Bentham from Lebanon and its biological activities.
2011
The essential oil of Nepeta glomerata from Lebanon was studied by means of GC and GC/MS analysis; 70 compounds were identified. The oil was constituted mainly by monoterpenes and the most abundant components were α-pinene, spathulenol and carvacrol. Nepeta glomerata oil showed antibacterial activity, particularly towards Gram-positive bacteria, and also inhibited LPS-induced NO production in macrophage cell line RAW 264.7, with an IC(50) value of 78.1 µg mL(-1). Furthermore, an in vitro cytotoxic assay showed that the oil was more active on a renal adenocarcinoma cell line (48% of inhibition of proliferation at 100 µg mL(-1)) in comparison to an amelanotic melanoma.
Towards Other Worlds, Towards Other Meanings: Screenplays on the Edge of the Plot
2015
Il saggio riguarda la tematizzazione del cinema nella letteratura, in particolare l'elaborazione di sceneggiature mai realizzate: dopo un'inquadratura generale dell'argomento, considera in particolare opere di Alba de Céspedes e Saul Bellow. The essay concerns cinema's representation in literature, focusing on novels about never realized screenplays, especially on those by Alba de Cespedes and Saul Bellow
Tempo lembrado, lido e experienciado no texto virtual
2015
In this article I will scrutinize Screen (2002, by WARDRIP-FRUIN & al.), a literary work set and experienced in a CAVE Virtual Reality environment, especially from the perspective of its temporal aspects. There are obvious themes of remembering, forgetting and textually constructing the past in this work, but most notably, Screen emphasizes the temporality of the reading act itself. I will analyze this highly special work in relation to the remembered, read, and bodily experienced time, and thus, attempt to better understand both the notion of fictive time and the temporality of fiction. Neste artigo vou examinar Screen (2002, por Wardrip-Fruin & al.), uma obra literária experimenta…
