Les cellules souches sont des cellules très importantes. Elles seules possèdent à la fois les capacités de se multiplier et de se différencier (se transformer en d’autres types cellulaires). Elles génèrent ainsi toutes les cellules qui forment nos tissus et organes durant le développement. Puis, durant toute la phase adulte, elles servent au renouvellement normal […]

This project focuses on the design, synthesis and characterization of coiled coil (CC) motifs as modular scaffolds for metal-mediated assembly and function. CCs are predictable a-helical assemblies in which oligomerization behavior can be tuned through sequence design, making them attractive scaffolds for incorporating metal-binding functionalities in a controlled manner. In this project, CC motifs will […]

L’OBV Yamaska a longtemps été une référence dans la région sur la qualité de l’eau. Cependant, dans les dernières années, une diminution des effectifs a réduit la portée de ses interventions dans la sphère agricole. L’agriculture constitue pourtant un pôle économique et culturel important dans la région et est responsable d’une partie des contaminants présents […]

Les vieilles forêts jouent un rôle central dans le maintien de la biodiversité et des fonctions écologiques forestières, mais leur prise en compte dans l’aménagement forestier demeure limitée par des outils de diagnostic reposant principalement sur des seuils d’âge et des proportions de forêts résiduelles. Cette approche ne permet pas d’évaluer adéquatement la qualité écologique […]

In this project, we will investigate the strain dynamics and antimicrobial sensitivity of the bacterial pathogen of honey bees, Melissococcus plutonius, which causes European foulbrood disease of honey bees.

This project will study how different human antibodies help protect us from viruses such as influenza, SARS-CoV-2, and RSV by working with individual immune cells and producing their antibodies in the lab. The student will grow and purify these antibodies, test how well they bind to viruses, and measure how effectively they activate important immune […]

La capacité du système moteur humain à produire et à contrôler la force repose sur l’interaction dynamique entre le système nerveux et les muscles squelettiques. Lors de tâches prolongées ou exigeantes, cette interaction s’adapte afin de maintenir la performance malgré la diminution progressive des capacités neuromusculaires associées à la fatigue. Ce projet vise à comprendre […]

Mutualisms, interactions in which two species benefit one another, are universal. It is estimated that every species engages in at least one mutualism. Mutualisms play key roles in natural ecosystems–providing essential ecosystem services, like pollination and nitrogen fixation–and even influence where species live. Despite their importance, very little is known about how mutualisms influence the […]

This project will test whether growth factors produced in-house at the host institute can reliably replace commercially purchased growth factors used to grow heart and kidney cells from human stem cells. These growth factors are essential but costly, and their performance can decline when they are repeatedly warmed and cooled during routine lab work. The […]

Avoiding collisions with other pedestrians is a daily necessity for individuals across all age groups. Unfortunately, age-related declines in older adults’ motor and sensory systems can negatively impact their ability to safely navigate the environment. For instance, decrements in muscular strength, balance, and cognitive function can impair one’s ability to adapt locomotion to environmental constraints. […]

This project will expand on a previous project on heat stress on calf microbiome with the prevalence of climate change. Young calves are particularly vulnerable because their immune and temperature regulation systems are not fully developed, and their gut microbiome—the community of bacteria, archaea, and viruses that support digestion and health—is still forming. In Japan, […]

Chemsex refers to the recreational use of psychoactive substances to enhance sexual experiences and is associated with increased sexual risk-taking and mental health issues, including substance dependence. One of the most commonly used substances in this context is isopropyl nitrite, owing to its low cost, wide availability, and ease of inhalation. In recent years, growing […]
