Improvement of balance in a 7-year-old child through a six-week learning programme
2018
Given that human beings are constantly subjected to equilibration processes, developing basic perceptual motor skills, especially balance, is important. The main purpose of this study is the validation of the tasks and the progression of activities that form the learning programme for balance development in a six-week didactic unit of 12 sessions (2 sessions per week), for 6 to 9 year old children (1st, 2nd, and 3rd grade of elementary school in Brazil). The changes in balance after applying the programme are also analysed through a new measuring protocol using baropodometry. Although the session was put into practice in a class of 28 children, data were extracted from a 7-year-old child. T…
La banlieue du "20 heures". Ethnographie de la production d'un lieu commun journalistique
2013
International audience; Plongés dans un collectif de travail régi par des logiques économiques (audience, productivité), le poids des sources légitimes et des modèles professionnels importés de l’audiovisuel commercial, les journalistes de France 2 fabriquent et perpétuent les lieux communs sur les habitants des quartiers populaires pour satisfaire dans l’urgence la commande de reportages prédéfinis par leur hiérarchie. À partir d’une enquête menée au plus près des pratiques quotidiennes des journalistes, ce livre propose une explication sociologique à la permanence des représentations réductrices véhiculées par certains contenus médiatiques.
Fabric control on strain and rupture of heterogeneous shale samples by using a non-conventional mechanical test
2004
Abstract This work was a part of the preliminary stage of the ANDRA project on a deep-seated research laboratory for the feasibility study of long-term radioactive waste storage in the Callovo–Oxfordian argillites of the Eastern part of the Paris Basin. These rocks are bedded, their density is about 2.4, and they contain an average of 30% carbonates and 25% quartz. Thick (5 mm) sections from cores were put through a non-conventional device called CGI testcell (CGI: Centre de Geologie de l'Ingenieur, i.e. Engineering Geology Centre). The aim of this versatile device is to achieve plane deformation tests under compressive uniaxial loading together with controlled temperature and humidity cond…
Low-fouling, mixed-charge poly-L-lysine polymers with anionic oligopeptide side-chains
2018
Biosensors and biomedical devices require antifouling surfaces to prevent the non-specific adhesion of proteins or cells, for example, when aiming to detect circulating cancer biomarkers in complex natural media (e.g., in blood plasma or serum). A mixed-charge polymer was prepared by the coupling of a cationic polyelectrolyte and an anionic oligopeptide through a modified "grafting-to" method. The poly-l-lysine (PLL) backbone was modified with different percentages (y%) of maleimide-NHS ester chains (PLL-mal(y%), from 13% to 26%), to produce cationic polymers with specific grafting densities, obtaining a mixed-charge polymer. The anionic oligopeptide structure (CEEEEE) included one cysteine…
Label-free piezoelectric biosensor for prognosis and diagnosis of Systemic Lupus Erythematosus
2017
[EN] An autoantigen piezoelectric sensor to quantify specific circulating autoantibodies in human serum is developed. The sensor consisted on a quartz crystal microbalance with dissipation monitoring (QCM-D) where TRIM21 and TROVE2 autoantigens were covalently immobilized, allowing the selective determination of autoantibodies for diagnosis and prognosis of Systemic Lupus Erythematosus (SLE). The sensitivity of the biosensor, measured as IC50 value, was 1.51 U/mL and 0.32 U/mL, for anti-TRIM21 and anti-TROVE2 circulating autoantibodies, respectively. The sensor is also able to establish a structural interaction fingerprint pattern or profile of circulating autoantibodies, what allows scorin…

A novel device for intracolonoscopy cleansing of inadequately prepared colonoscopy patients: a feasibility study.
2019
Abstract Background The importance of high quality preprocedural bowel preparation is widely acknowledged, but suboptimal bowel cleansing still occurs in up to 20 % of all colonoscopy patients. The aim of this study was to evaluate the performance of a novel intraprocedural cleaning device for cleaning poorly prepared colons. Methods This multicenter feasibility study included patients aged 18 – 75 years who were referred for colonoscopy. Intraprocedural cleaning was performed in patients after a limited preprocedural bowel preparation regimen (2 days of dietary restrictions and 2 × 10 mg bisacodyl). The primary outcome was the proportion of adequately prepared patients (Boston Bowel Prepar…
Study of Glycemic Variability Through Time Series Analyses (Detrended Fluctuation Analysis and Poincaré Plot) in Children and Adolescents with Type 1…
2016
Time series analysis provides information on blood glucose dynamics that is unattainable with conventional glycemic variability (GV) indices. To date, no studies have been published on these parameters in pediatric patients with type 1 diabetes. Our aim is to evaluate the relationship between time series analysis and conventional GV indices, and glycosylated hemoglobin (HbA1c) levels.This is a transversal study of 41 children and adolescents with type 1 diabetes. Glucose monitoring was carried out continuously for 72 h to study the following GV indices: standard deviation (SD) of glucose levels (mg/dL), coefficient of variation (%), interquartile range (IQR; mg/dL), mean amplitude of the la…
Influence of Demographic and Lifestyle Variables on Plasma Magnesium Concentrations and Their Associations with Cardiovascular Risk Factors in a Medi…
2020
Several studies have shown that a low magnesium (Mg) intake in the diet is associated with greater cardiovascular risk and greater risk of diabetes. However, the results are not consistent in all populations. To minimize the biases derived from diet measurement, more objective biomarkers of magnesium status have been proposed. Although there is still no ideal biomarker for Mg, several studies have shown that plasma Mg concentrations could be a relatively acceptable biomarker for cardiovascular risk assessment. However, further studies are required to better characterize this marker in different populations. Our aim was to analyze the association between plasma Mg concentrations (measured th…

[Background] Although the association between glutamate and glutamine in relation to cardiometabolic disorders has been evaluated, the role of these metabolites in the development of atrial fibrillation (AF) and heart failure (HF) remains unknown.
