Environmental effects on the covariation among pace-of-life traits
2019
Pace‐of‐life syndromes (POLSs) are suites of life‐history, physiological and behavioural traits that arise due to trade‐offs between allocation to current and future reproduction. Traits generally show covariation that can arise from genetic and environmental influences on phenotypes and constrain the independent evolution of traits, resulting in fitness consequences and impacts on population dynamics. The notion that correlations among traits may vary among populations along environmental gradients suggests an important role for the environment in shaping and maintaining POLSs. However, no synthesis has been attempted of the myriad ways in which environmental factors should influence POLSs…

Evolutionary advantage conferred by an eukaryote-to-eukaryote gene transfer event in wine yeasts
2015
Although an increasing number of horizontal gene transfers have been reported in eukaryotes, experimental evidence for their adaptive value is lacking. Here, we report the recent transfer of a 158-kb genomic region between Torulaspora microellipsoides and Saccharomyces cerevisiae wine yeasts or closely related strains. This genomic region has undergone several rearrangements in S. cerevisiae strains, including gene loss and gene conversion between two tandemly duplicated FOT genes encoding oligopeptide transporters. We show that FOT genes confer a strong competitive advantage during grape must fermentation by increasing the number and diversity of oligopeptides that yeast can utilize as a s…
Use of translational genomics to identify genes important for legume seed filling
2013
International audience; Translational genomics, i.e., the transfer of genetic information from model species to cultivated crops, is on the brink of revolutionizing plant breeding. The recent publication of genomic sequences for several cultivated legumes is also accelerating this process. For pea, recent highthroughput RNA sequencing, and the prospect of a genome sequencing project, will further accelerate the transfer of information from the Medicago truncatula model to the cultivated crop. We have been using genomics approaches with Medicago as a tool to identify key genes determining seed yield and composition in closely related legumes. Analyses of the proteome and transcriptome of the…
Le médicament homéopathique dans l'histoire du médicament, Co construction, confrontation, coopération. Histoire, Transmission, Représentation
2007
The dynamics of this thesis resides in the search for the breach between the historical positioning (in relation to scientific fact itself) of homeopathic medication in the history of medical sciences, and the representation made of it in the past and present. By distinguishing what may be at stake, we are led to identify the positioning and impact of the mode of transmitting scientific fact as lacking a historical link to the history of medical sciences, notably medication. Our research hypothesis thus postulates that the transmission mode is at the source of discrepancies in representation. The links between context breakthroughs, such as the role of influences, are just parameters that, …
ESSAI RANDOMISÉ POUR ÉVALUER L’EFFICACITÉ ET LA SÉCURITÉ DE TRAITEMENTS CHEZ DES PATIENTS AMBULATOIRES ATTEINTS DE COVID-19 AYANT DES FACTEURS DE RIS…
2021
Context. The Covid-19 pandemic is of unprecedented magnitude and has had major social and health consequences. Primary care professionals, mainly general practitioners, ensure the care of most patients with Covid-19. An early-stage treatment administered to patients with risk factors for developing a severe disease could reduce hospitalization and death rates. No treatment is currently validated in this indication. Objectives. To evaluate the safety and efficacy of experimental candidate agents delivered in outpatient settings to reduce the risk of hospitalization or death in at-risk patients with early-stage proven Covid-19 and no indication for hospital admission. Methods. Multicentric, o…
Trends in perceived school stress among adolescentsin five Nordic countries 2002–2014
2019
Abstract Associations between school-related stress and poor health, risk behaviours and low well-being are well documented. The aim of this paper was to estimate trends of perceived school stress experienced by boys and girls of different ages in the Nordic countries, and to describe trends in school stress between the Nordic countries. Nordic data from the Health Behaviour in School-aged Children study (HBSC) between 2002 and 2014 were used. The participants were aged 11–16 years. School stress was measured by a single item; “How pressured do you feel by schoolwork?” The participants answering “some” or “a lot” were categorised as reporting school stress. Sweden, Norway and Denmark had …
Data from: Parasitic wasp-associated symbiont affects plant-mediated species interactions between herbivores
2018
Microbial mutualistic symbiosis is increasingly recognised as a hidden driving force in the ecology of plant–insect interactions. Although plant‐associated and herbivore‐associated symbionts clearly affect interactions between plants and herbivores, the effects of symbionts associated with higher trophic levels has been largely overlooked. At the third‐trophic level, parasitic wasps are a common group of insects that can inject symbiotic viruses (polydnaviruses) and venom into their herbivorous hosts to support parasitoid offspring development. Here, we show that such third‐trophic level symbionts act in combination with venom to affect plant‐mediated interactions by reducing colonisation o…
Evaluation of the animal-assisted therapy in Alzheimer's disease
2017
Animal-assisted therapy sessions have been set up in a protected unit for patients with a dementia-related syndrome. The aim is to measure the effects of animal-assisted therapy on behavioural disorders in daily life and care. The results obtained provided some interesting areas to explore and recommendations with a view to optimising the implementation of such a system.
