Water and temperature contribution to the structuration of starch matrices in the presence of flavour
2015
The effect of hydrothermal treatments and flavours addition on starch structure and its physical properties were studied. Native wheat starch was treated at 2 different hydrations (water-starch ratios: 50/50 and 80/20 g w/w) and temperatures (65 and 85 °C) in the presence of flavours (ethyl hexanoate and 2-hexanone). The freshly prepared samples were subjected to DSC and flavour analysis. Flavour inclusion complex could not be detected by DSC, however the result of flavour analysis proved that there were flavours interactions with starch. Both ethyl hexanoate and 2-hexanone interacted with starch at similar rates. The highest flavour loss was found in the samples at high hydration and heate…

Bleomycin induced pulmonary toxicity and its subpleural onset
2016
Idiopathic Pulmonary Fibrosis (PF) is a rare and devastating disease without efficient treatment at this time. Idiopathic FP is characterized by accumulation of myofibroblasts and has a typical sub-pleural onset suggesting a role of the pleura in the disease. Transforming Growth Factor (TGF)-ß1 induces transformation of pleural mesothelial cells (PMC) into active cells exhibiting myofibroblast phenotype. Heat shock proteins can act as regulator of the TGF-ß1 signaling. A role for caspase-1/IL-1ß axis has already been described in animal models of PF.The heat shock protein AlphaB-crystallin has been studied in PF at the PMC level and the importance of caspase-1/IL-1ß axis has been investigat…
Etude de la stabilité de films industriels de PLA et de leur modification de surface pour des applications en tant qu'emballage alimentaire biodégrad…
2017
Poly(lactic acid) (PLA) is a biodegradable and renewable polyester, which is considered as the most promising eco-friendly substitute of conventional plastics. It is mainly used for food packaging applications, but some drawbacks still reduce its applications. On the one hand, its low barrier performance to gases (e.g. O2 and CO2) limits its use for applications requiring low gas transfer, such as modified atmosphere packaging (MAP) or for carbonate beverage packaging. On the other hand, its natural water sensitivity, which contributes to its biodegradation, limits its use for high moisture foods with long shelf life.Other biopolymers such as wheat gluten (WG) can be considered as interesti…
Le désherbage d’automne contre l’ergot du seigle les traitements herbicides d’automne, un levier chimique efficace de lutte contre l’ergot du seigle
2013
Context and study: Trials in field allowed to show a link between a good grass weeding (blackgrass and rye grass) and extent of ergot contaminations. Makhteshim Agan France and Arvalis tested on 15 trials in 2011-2012, 2 ureas, as isoproturon against blackgrass, alone or in pro-gram with a sulfonylurea, to evaluate their indirect effect against ergot. Field trials were set up on sensitive crops to ergot (rye, wheat and triticale) infested with artificial ergot contaminations and weed seeds sensible to ALS. Contaminations were evaluated first in field on weeds and on crop, and then on harvest, by assessing sclerotia and alkaloids content in harvested samples. results: For all evaluation mean…

Capacité de stockage de carbone dans le sol de variétés anciennes et modernes de blés
2021
National audience; Gérer convenablement les puits de carbone pourrait permettre de compenser les émissions deCO2. Étant donné la superficie des terres arables, les pratiques sur les sols agricoles peuventservir de levier d'action. Dans ce projet de thèse, nous faisons l’hypothèse que la séquestrationdu carbone est modifiée par le développement et la profondeur du système racinaire descultures. À ce titre, les variétés de blé anciennes sont réputées pour leur système racinaire plusprofond que celui des modernes. De plus, l’apport d’intrants chimiques de synthèse, dont lesengrais azotés, pourrait modifier la dynamique du carbone du sol. Dans une étude de terrain,des variétés modernes et ancie…
Trait distribution within winter wheat fields can partly be explained by disturbances and competition for resources
2013
International audience; Weed species are not homogeneously distributed into field elements (Cordeau et al. 2012)*.In a field, weed species are mainly competing with the crop and constrained by management practice (i.e.disturbances). In the crop edge, less unfavorable conditions for weed development (i.e.absence of direct crop competition,l ess frequent disturbances could explain the greater diversity of weeds.To understand this observation, a functional approach base dont raits known to respond both to disturbances and to competitive or facilitative interactions can be used.Our assumptions are that(i)the crop edge is likely to all owawi derrange of ecological strategies thus promoting speci…
