New grafted PLA-g-PEG polymeric nanoparticles used to improve bioavailability of oral drugs
(2015-10-21)
Les nanoparticules (NPs) de polymère ont montré des résultats prometteurs pour leur utilisation comme système de transport de médicaments pour une libération contrôlée du médicament, ainsi que pour du ciblage. La ...
Hydration forces at solid and fluid biointerfaces
(American Vacuum Society, 2016-01)
We review the different molecular mechanisms giving rise to the repulsive hydration force between biologically relevant surfaces such as lipid bilayers and bio-ceramics. As we will show, the hydration force manifests ...
Data-adaptive longitudinal model selection in causal inference with collaborative targeted minimum loss-based estimation
(Wiley, 2019)
Causal inference methods have been developed for longitudinal observationalstudy designs where confounding is thought to occur over time. In particular,one may estimate and contrast the population mean counterfactual ...
Wear protection without surface modification using a synergistic mixture of molecular brushes and linear polymers
(American Chemical Society, 2017-01-10)
We describe the design of lubricating and wear protecting fluids based on mixtures of bottlebrushes (BB) and linear polymers solutions. To illustrate this concept we used hyaluronic acid (HA) - a naturally occurring linear ...
Bioinspired microstructures of chitosan hydrogel provide enhanced wear protection
(Royal Society of Chemistry, 2018-02-16)
We describe the fabrication of physical chitosan hydrogels exhibiting a layered structure. This
bilayered structure, as shown by SEM and confocal microscopy, is composed of a thin dense
superficial zone (SZ), covering a ...
Estimating treatment importance in multidrug-resistant tuberculosis using Targeted Learning : an observational individual patient data network meta-analysis
Estimating MDR-TB treatment importance using TMLE
(Wiley, 2019)
Persons with multidrug‐resistant tuberculosis (MDR‐TB) have a disease resulting from a strain of tuberculosis (TB) that does not respond to at least isoniazid and rifampicin, the two most effective anti‐TB drugs. MDR‐TB ...
Nanoparticle heterogeneity : an emerging structural parameter 2 influencing particle fate in biological media?
(Royal Society of Chemistry, 2018-11-27)
Drug nanocarriers’ surface chemistry is often presumed to be uniform. For instance, the polymer surface coverage and distribution of ligands on nanoparticles are described with averaged values obtained from quantification ...
Intermolecular interactions between Bottlebrush Polymers boost the protection of surfaces against frictional wear
(ACS Publications, 2018-05-30)
Polymers exhibiting the bottlebrush (BB) architecture have excellent lubricating properties. However, to motivate their use in real life systems, they must also protect surfaces against frictional damage. In this article, ...
Insiders, smart drugs et pharmaceuticalisation : éléments pour une typologie de la nouvelle déviance conformiste
(Département de sociologie de l’Université du Québec à Montréal & Athéna éditions, 2016)
La multiplication des usagers et usagères des smart drugs sur les campus universitaires, des go-pills dans l’armée ou encore des coast-to-coast chez les camionneurs de longue distance invite à revisiter la légitimité ...
