Development of a probiotic to improve poultry health and performance.

New bacterial culture and sequencing techniques have allowed better characterization of the microbiota. Microbiota profiles containing high diversity are associated with better intestinal health, immune system and protection against pathogens. In nature, each animal species is naturally selected and hosts a very specific and diverse microbiota. However, current animal production systems impose factors that reduce […]

Modélisation de la reconnaissance de visages: Une étude combinant MEG et réseaux de neurones artificiels

Ce projet est l’interaction entre les deux champs de recherches, Intelligence Artificielle (IA) et Neurosciences. Cette interaction est également permise par le développement récent de modèles, provenant de l’IA, ayant pour but d’aider la compréhension de certains processus neuronaux. Nous souhaitons contribuer à cette interaction en nous concentrant sur la modélisation des aires visuelles impliquées […]

“Peuple du ciel” de J. M. G. Le Clézio: une traduction commentée

Il s’agit d’une traduction commentée du conte “Peuple du ciel”, de Jean-Marie Gustave Le Clézio, publié en 1978 dans le livre Mondo et autres histoires. Le conte pour enfants, encore sans traduction en portugais, a une atmosphère onirique et évoque la liberté de contact avec la nature et les phénomènes mythologiques. Le texte en prose […]

Molecular decomposition of localizable Hardy spaces and applications

The theory of real Hardy spaces, denoted by Hp, and its local version hp, has been extensively developed since the 1960s. Among the countless important properties of these spaces, one can make note the atomic and molecular decomposition, which allows to describe a distribution on this space in terms of particular functions called atoms and […]

Genome-wide association study (GWAS) for biological nitrogen fixation and protein content in soybean (Glycine max)

The biologically-fixed N is more efficiently converted into protein than mineral N from fertilizers. As low protein content is currently a topic of great concern in many soybean-growing areas, improvement of BNF efficiency may reach higher protein levels with lower environmental impacts. Genome-wide association studies (GWAS) have shown excellent results in the association of single-nucleotide […]

Simulation of permafrost degradation considering heat adg

Permafrost is currently degrading due to climate changes in northern regions, resulting in several impacts on civilian infrastructure and natural environments. These changes can ultimately lead to a shift in the water cycle from a surface flow regime to a groundwater flow regime following permafrost degradation. In order to anticipate such impacts, it is important […]

The Bibliothèque de la Pléiade: The Social History of the Making of Cultural Goods and “Literary Giants”

This project aims to examine — through “la Bibliothèque de la Pléiade”, the French publishing world’s most prestigious book collection made of Bible paper, leather cover, and gold — the relation between the choices made to publish some literary works and the formation of “literary giants”, considered authors that achieve the status of being called […]

Développement d’une plateforme moléculaire pour le dosage de mucines oculaires

Certaines pathologies, comme la maladie des yeux secs, viennent perturber la composition du film lacrymal qui protège la cornée. Plus précisément, ces pathologies ont un impact sur la composition en protéines de la dernière couche du film lacrymal. Ce débalancement peut avoir un impact sur l’efficacité des vecteurs de médicaments de l’équipe de recherche de […]

Étude de la dynamique saisonnière des communautés parasitaires et du microbiote de Mesonauta festivus dans le bassin hydrologique du Rio Negro

Le fleuve Negro est caractérisé par de grandes fluctuations saisonnières du niveau de l’eau allant jusqu’à 15 m. Cette dynamique saisonnière est connue pour avoir un impact majeur sur le comportement des poissons et sur leur exploitation par les Ribeirinhos – tribus traditionnelles amazoniennes. Entre autres, certaines études ont détecté une plus grande prévalence d’infection […]

The role of Serotonin and the effect of SSRIs on the placental iron transport system

Depression affects up to 20% of pregnancy. If left untreated, antenatal depression increases the risk of complicated pregnancy and abnormal fetal development. The selective serotonin reuptake inhibitors (SSRIs) are the most commonly used treatment method for perinatal depression, while the risk of the drug on the placental function and fetal development remains controversial. Iron deficiency […]

Development of Mathematical Methods for 3D Reconstruction in Cryogenic Electron-Microscopy

For the past several years, advances in cryogenic-electron microscopy (cryo-EM)have led to a revolution in structural biology, for which the Nobel Prize in Chemistrywas awarded in 2017. To enable the 3D reconstruction of atomic structures, thedevelopment of mathematical methods has been instrumental to address thesample size, noise, and geometric complexity inherent with cryo-EM data. Tosignificantly […]
