Etude dynamique et structurale de biomolécules par microscopie à force atomique HS-AFM : application à une petite protéine de choc thermique sHsp

2012

The atomic force microscopy (AFM) gives access to the topography of organic and inorganic samplesat the atomic scale. The latest innovations offer the possiblity to understand the sample nano-mechanicalproperties (elasticity, adhesion...). Its feature set allows overcoming the demands of nanotechnology,both in the fields of physics, chemistry and biology.However, understanding biological processes require faster acquisitions for the atomic forcemicroscopy, less than a second per frame. As conventional equipment does not offer the possibility toovercome the constraint of time for dynamical studies, a prototype of high-speed atomic forcemicroscope (HS-AFM) was developed in partnership with Pr…

Les phytoprotecteurs (« Safeners ») associés aux herbicides jouent-ils un rôle dans la sélection de résistances non liées à la cible ?

2016

Do herbicide-associated "Safeners" play a role in the selection for non-target-site resistances ? To ensure or improve crop selectivity, some herbicide molecules are applied in association with a “safener”. Safeners are compounds that, at the rate applied, enhance herbicide-degrading metabolic pathways supposedly specifically in crop plants. The metabolic pathways enhanced by safeners in crop plants are highly similar to those exacerbated in taxonomically closely related weed species that evolved non-target-site based resistance (NTSR) to herbicides. Herein, we show an enhancing effect of herbicide safeners on NTSR in a major noxious grass weed: rye-grass (Lolium sp.).

Evénements de vie chez les adolescents en désaffiliation contextuelle

2006

International audience; Dans le cadre théorique du modèle bioécologique de Bronfenbrenner, nous avons élaboré deux échelles évaluant la qualité de transaction des adolescents vis-à-vis de deux contextes de vie significatifs : la famille et l’école. Ces échelles permettent d’identifier les adolescents en situation de désaffiliation familiale et/ou scolaire (perception négative, voire rejet de la famille, de l'école). Nous avons déjà montré que la désaffiliation simple (familiale ou scolaire) avait un effet délétère sur la santé des adolescents et que la désaffiliation double (familiale et scolaire) amplifiait les risques de troubles de santé. La présente recherche porte sur les liens entre l…

PV-Alert: Fog Computing based Architecture for Safeguarding Vulnerable Road Users

2018

High volumes of pedestrians, cyclists and other vulnerable road users (VRUs) have much higher casualty rates per mile; not surprising given their lack of protection from an accident. In order to alleviate the problem, sensing capabilities of smartphones can be used to detect, warn and safeguard these road users. In this research we propose an infrastructure-less fog-based architecture named PV-Alert (Pedestrian-Vehicle Alert) where fog nodes process delay sensitive data obtained from smartphones for alerting pedestrians and drivers before sending the data to the cloud for further analysis. Fog computing is considered in developing the architecture since it is an emerging paradigm that has p…

Accessibilità e fruizione delle raccolte

2015

Il contributo fa il punto sulla formazione universitaria nel campo dei beni culturali, evidenziando il progressivo depauperamento degli ambiti inerenti, in particolare, il patrimonio archivistico e bibliotecario, attraverso un esame dei dati MIUR e la comparazione dell'offerta formativa degli atenei. Viene evidenziato il nesso indispensabile tra la formazione specialistica e la possibilità di tutelare e valorizzare, consentire l'accessibilità e rendere 'pubblico' il patrimonio - secondo l'istanza che proviene da più parti, e che riguarda l'intero patrimonio culturale nelle sue varie forme e declinazioni -, facendone oggetto di una reale condivisione, necessariamente mediata dagli specialist…

Prediction of hydraulic and acoustic properties of open-graded mixes

2014

The use of open-graded mixes increases significantly the hydraulic permeability of pavement and contributes to reduce the noise impact in comparison to traditional pavement. Such characteristics are very appealing and would greatly increase driver's safety. However, during service life, the pores tend to be clogged by many factors among them secondary traffic compaction and filling of voids by fine materials are relevant, especially on heavy routes. In this case the noise reduction and drainage capabilities will gradually disappear, causing serious problems for road safety and maintenance. In this paper we propose a simulation approach in order to predict the drainage and acoustic behavior …

Durability of Dolutegravir-Based Regimens: A 5-Year Prospective Observational Study

2021

This study evaluates the frequency and causes of dolutegravir (DTG) discontinuation along 5 years of follow-up, in both antiretroviral treatment (ART)-naive and experienced people living with HIV (PLWH). This is a prospective multi-center cohort study enrolling PLWH on DTG from July 2014 until November 2020. DTG-durability was investigated using the Kaplan-Meier survival curve. The Cox proportional-hazards model was used for estimating the hazard ratio (HR) of DTG discontinuation for any cause, and for adverse events (AEs). Nine hundred sixty-three PLWH were included, 25.3% were women and 28.0% were ART-naive. Discontinuations for any causes were 10.1 [95% confidence interval (95% CI) 8.9-1…

Sustainability Assessment of Agricultural Systems in Paraguay: A Comparative Study Using FAO’s SAFA Framework

2019

Sustainability is a topic that is at the center of current discussions in the political, economic, social, and environmental fields. For its analysis, an integral and multidisciplinary vision is needed. This work aims to assess the sustainability of agricultural systems in Paraguay through a comparison applying SAFA (Sustainability Assessment of Food and Agriculture Systems) indicators. The research focuses on 15 case studies on the territory of the Eastern Region of Paraguay divided into five classes of agricultural systems: agribusiness, conventional peasant family farming, agroecological peasant family farming, neo-rural farming, and indigenous agriculture. Data were collected through in…

Guidance on allergenicity assessment of genetically modified plants

2017

Abstract This document provides supplementary guidance on specific topics for the allergenicity risk assessment of genetically modified plants. In particular, it supplements general recommendations outlined in previous EFSA GMO Panel guidelines and Implementing Regulation (EU) No 503/2013. The topics addressed are non‐IgE‐mediated adverse immune reactions to foods, in vitro protein digestibility tests and endogenous allergenicity. New scientific and regulatory developments regarding these three topics are described in this document. Considerations on the practical implementation of those developments in the risk assessment of genetically modified plants are discussed and recommended, where …
