In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Orange emission in Pr3+-doped fluoroindate glasses [PDF]
, 2012 We synthesize and study the properties of praseodymium doped fluoroindate glasses. Glass compositions with praseodymium molar concentrations up to 5% were obtained with good optical quality. Thermal, optical, and luminescence properties are investigated.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Une poursuite d’études accompagnée
Cahiers de la Recherche sur l'Education et les Savoirs, 2009 Higher Technicians Sections (STS) allow underclass families to stay into the educational system after Baccalauréat thanks to a new distribution of roles for school, students and their parents within higher education.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Spécificité de la problématisation scientifique : le travail d’abstraction et de généralisation
Recherches en Éducation, 2007 Dans notre souci de comprendre la problématisation scientifique, et en prolongement de la présentation au symposium « Probléma » de Chicoutimi, nous explorons ici une caractéristique fondamentale des problématisations théoriques (en sciences) : le ...

Apprentissages scientifiques : ce qui se construit et ce qui se transmet
Recherches en Éducation, 2007 Nous discutons ici des relations entre construction (par les élèves) et transmission (par le professeur) dans les apprentissages scientifiques. Pour cela nous présentons trois cas où ces relations sont différentes.
