Proton-irradiated breast cells: molecular points of view
2019
Abstract Breast cancer (BC) is the most common cancer in women, highly heterogeneous at both the clinical and molecular level. Radiation therapy (RT) represents an efficient modality to treat localized tumor in BC care, although the choice of a unique treatment plan for all BC patients, including RT, may not be the best option. Technological advances in RT are evolving with the use of charged particle beams (i.e. protons) which, due to a more localized delivery of the radiation dose, reduce the dose administered to the heart compared with conventional RT. However, few data regarding proton-induced molecular changes are currently available. The aim of this study was to investigate and descri…
Body mass index categories and anxiety symptoms among adults aged =?50 years from low and middle income countries.
2021
Background: Body weight may be a risk factor for anxiety; however, there is a scarcity of studies on this association in older adults especially from low and middle income countries (LMICs). Therefore, we investigated the association between body mass index (BMI) and anxiety symptoms among adults aged ≥ 50 years from 6 LMICs. Methods: Cross-sectional, community-based, nationally representative data from the World Health Organization (WHO) Study on global AGEing and adult health (SAGE) were analyzed. The BMI was based on measured weight and height and was categorized as: < 18.5 kg/m2 (underweight), 18.5–24.9 kg/m2 (normal weight), 25.0–29.9 kg/m2 (overweight), 30.0–34.9 kg/m2 (obesity cla…
Modèle des voies réflexes et cérébelleuses, permettant le calcul de fonctions inverses et la commande d'un segment mécanique mobile
2004
14/07/2004; La commande et le contrôle des mouvements des membres par les voies cérébelleuses et réflexes sont modélisées au moyen d'un circuit dont la structure est déduite de contraintes fonctionnelles. 1/ La première contrainte est que les mouvements rapides des membres doivent être précis, quoiqu'ils ne puissent pas être commandés en boucle fermée au moyen de signaux sensoriels. Les voies qui préparent les ordres moteurs doivent donc contenir des fonctions inverses approximées des fonctions biomécaniques du membre et des muscles. Or une telle fonction peut être calculée au moyen de boucles de rétroaction parallèles, dont la structure est comparable à l'anatomie des voies cérébelleuses. …
The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…
2019
The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…
Incorporation of Pt(II) complex with [amino-2(methylthio)(1,2,4)triazole-(1,5-a)pyrimidine-6-carboxylic-acid] ligand in MCM41 for controlled release
2015
Drug carriers play a critical role for the loading and the release of the drug. A promising frontier is represented by a new class of innovative medicines that represents directional transport vehicles "drug delivery" and consist of assembled structures carrier (nano)-drug. Silica-based materials, nontoxic, biocompatible, have been used as adjuvant and excipient in pharmaceutical technology. In this class of compounds, the mesoporous materials, such as MCM41, SBA-15 and hexagonal mesoporous silica, have been investigated for medication and drug delivery due to their properties. In fact, these materials show a large specific pore volume made up of regular pores having a diameter in the nanom…
Computational Techniques for the Analysis of Small Signals in High-Statistics Neutrino Oscillation Experiments
2020
The current and upcoming generation of Very Large Volume Neutrino Telescopes – collecting unprecedented quantities of neutrino events – can be used to explore subtle effects in oscillation physics, such as (but not restricted to) the neutrino mass ordering. The sensitivity of an experiment to these effects can be estimated from Monte Carlo simulations. With the high number of events that will be collected, there is a trade-off between the computational expense of running such simulations and the inherent statistical uncertainty in the determined values. In such a scenario, it becomes impractical to produce and use adequately-sized sets of simulated events with traditional methods, such as M…

TAGS measurements for neutrino physics and applications
2017
En la actualidad un gran número de temas de interés en Física Nuclear continúan planteando interrogantes fundamentales. Una de las fuentes de información más esclarecedoras es el proceso de la desintegración beta. Gracias al estudio experimental de este fenómeno en núcleos alejados de la estabilidad, es posible extraer valiosa información sobre estructura nuclear. En esa línea, esta tesis se centra en la determinación de las intensidades beta que pueblan los estados excitados del núcleo hijo en la desintegración beta de núcleos exóticos de gran interés. Para ello se ha utilizado la técnica de Espectroscopía gamma de Absorción Total (TAGS, por sus siglas en inglés), basada en el uso de grand…
Strategie spaziali e guerre di segni: brand della ristorazione non convenzionale
2021
Nell’ambito della ristorazione non convenzionale – da metà Novecento a oggi, e chissà per quanto ancora – è in atto una guerra di segni che mette in campo differenti concezioni dello spazio. A scorrere, e ricostruire testualmente, i principali marchi del food (fast, slow e derivati) si percepisce come questo tenace conflitto tenga in costante connessione – al modo del principio hjelmsleviano d’espansione/condensazione del discorso – i logo aziendali con l’architettura dei locali, dove i primi alludono ai secondi e, viceversa, i secondi danno fisicamente riscontro alla topologia che i primi incessantemente mettono in opera. Se, come sappiamo, l’uomo è ciò che mangia, lo è perché pasteggia se…
