Situación vacunal e inmunogenicidad a largo plazo en una cohorte de pacientes con enfermedades reumáticas en un hospital terciario de España
2023
Introducción: Los pacientes pediátricos con enfermedades reumáticas tienen un mayor riesgo de tener infecciones. Las vacunas han demostrado ser útiles en la prevención de procesos infecciosos, sin embargo los datos sobre la inmunidad generada por las vacunas a largo plazo en estos pacientes ha sido escasamente reflejada en la literatura. Objetivo: El objetivo de este estudio es evaluar si existen diferencias en los títulos de anticuerpos (media geométrica) o en la prevalencia de seroprotección, a largo plazo, entre pacientes pediátricos con enfermedades reumáticas y niños sanos en relación a las siguientes vacunas sistemáticas: sarampión, rubéola, parotiditis, tétanos, difteria, y H. influe…
Exercise-Induced Extracellular Vesicles Delay the Progression of Prostate Cancer
2022
Increasing evidence suggests that regular physical exercise not only reduces the risk of cancer but also improves functional capacity, treatment efficacy and disease outcome in cancer patients. At least partially, these effects are mediated by the secretome of the tissues responding to exercise. The secreted molecules can be released in a carrier-free form or enclosed into extracellular vesicles (EVs). Several recent studies have shown that EVs are actively released into circulation during physical exercise. Here, we for the first time investigated the effects of exercise-induced EVs on the progression of cancer in an F344 rat model of metastatic prostate cancer. Although we did not observe…
Accordo e persona nell’argomentazione: il caso dell’ad hominem.
2012
Is the ad hominem argument a fallacy or not? In this paper I will try to demonstrate that an ad hominem is not intrinsically fallacious and that the speaker’s personal convictions, commitments and actions are deeply involved in every argument. This paper starts with a comparison between dialectical and rhetorical approaches to the argumentation, and, in particular, to the agreement. Briefly: from a dialectical standpoint, the argumentation is aimed at resolving a difference of opinion or a disagreement. On the other hand, from the rhetorical perspective argumentation also often deals with dialogues of the deaf, with incommensurable points of view. The agreement is a key concept of Perelman’…
La construcción discursiva de la identidad femenina en la prensa franquista: el ejemplo de Y. Revista para la mujer (1938–1945)
2022
La presente tesi analizza la costruzione dell’identità della donna nella stampa del primo franchismo. Nello specifico, oggetto di questo studio è “Y. Revista para la mujer”, un mensile che, da febbraio del 1938 a dicembre del 1945, è stato l’organo propagandistico ufficiale della Sección Femenina. L’obiettivo principale è descrivere non solo i tratti e ruoli che compongono tale identità, ma anche gli espedienti linguistico-discorsivi utilizzati per definirli, legittimarli ed esaltarli. A tal fine, l’analisi realizzata segue le indicazioni dell’Analisi Critica del Discorso (soprattutto, van Dijk, 1999, 2001, 2003, 2012) e della Teoria dell’Argomentazione (Anscombre e Ducrot, 1994; Fuentes e …
Complexes of Glycolic Acid with Nitrogen Isolated in Argon Matrices. I. Structures and Thermal Effects.
2019
Molecular complexes between glycolic acid and nitrogen were studied in a low-temperature argon matrix with FTIR spectroscopy, and supported by MP2 and BLYPD3 calculations. The calculations indicate 11 and 10 stable complex structures at the MP2 and BLYPD3 levels of theories, respectively. However, only one hydrogen-bonded complex structure involving the most stable SSC conformer of glycolic acid was found experimentally, where the nitrogen molecule is bound with the carboxylic OH group of the SSC conformer. The complex shows a rich site structure variation upon deposition of the matrix in different temperatures and upon annealing experiments, which provide interesting prospects for site-sel…
Experimental FTIR-MI and Theoretical Studies of Isocyanic Acid Aggregates
2023
Homoaggregates of isocyanic acid (HNCO) were studied using FTIR spectroscopy combined with a low-temperature matrix isolation technique and quantum chemical calculations. Computationally, the structures of the HNCO dimers and trimers were optimized at the MP2, B3LYPD3 and B2PLYPD3 levels of theory employing the 6-311++G(3df,3pd) basis set. Topological analysis of the electron density (AIM) was used to identify the type of non-covalent interactions in the studied aggregates. Five stable minima were located on the potential energy surface for (HNCO)2, and nine were located on the potential energy surface for (HNCO)3. The most stable dimer (D1) involves a weak, almost linear N-H⋯N hydrog…
Light-induced, site-selective isomerization of glyoxylic acid in solid xenon
2014
Abstract The isomerization of glyoxylic acid (GA) and its water complex was studied in a low temperature xenon matrix. The aim of these studies was to understand how xenon environment affects the cis-trans GA interconversion upon near infrared irradiation. In solid xenon, the GA conformers are embedded in two different matrix sites. These show up as different vibrational bands of GA that exhibit different kinetic rates of isomerization. Upon complexation with water, the isomerization process slows down. Xenon matrix appears not to affect energy relaxation process via intramolecular or intermolecular hydrogen bond as compared with previous experiments in an argon.
Monitoring and data quality assessment of the ATLAS liquid argon calorimeter
2014
The liquid argon calorimeter is a key component of the ATLAS detector installed at the CERN Large Hadron Collider. The primary purpose of this calorimeter is the measurement of electron and photon kinematic properties. It also provides a crucial input for measuring jets and missing transverse momentum. An advanced data monitoring procedure was designed to quickly identify issues that would affect detector performance and ensure that only the best quality data are used for physics analysis. This article presents the validation procedure developed during the 2011 and 2012 LHC data-taking periods, in which more than 98% of the proton-proton luminosity recorded by ATLAS at a centre-of-mass ener…
Diritti e interpretazione. Il ragionamento giuridico nello Stato costituzionale
2010
Il libro illustra gli effetti che il discorso dei diritti produce sull’argomentazione giuridica. Negli ordinamenti giuridici costituzionalizzati il giurista sembra aver definitivamente dismesso l’abito del mero esegeta dei testi di legge (ereditato dalla tradizione culturale del positivismo legalista ottocentesco), per assumere un ruolo attivo di promozione e attuazione dei diritti fondamentali e dei valori costituzionali. La centralità dei diritti fondamentali contribuisce a rimodulare i rapporti fra potere legislativo e potere giudiziario, talora anche in termini di concorrenza reciproca, e nelle corti trovano posto nuove tecniche argomentative che sembrano avvicinare il ragionamento giur…
