A recently proposed model which explains the CPE response exhibited by metal/coating/electrolyte systems as the result of power-law dependences of the coating resistivity and permittivity along their thickness is revisited and applied to three different coating/electrolyte combinations. It is shown that resistivity profiles may be determined, and t...

Trypanosomatids sequester large parts of glucose metabolism inside specialised peroxisomes, called glycosomes. Many studies have shown that correct glycosomal compartmentalization of glycolytic enzymes is essential for bloodstream-form Trypanosoma brucei. The recent finding of pore-forming activities in glycosomal membrane preparations and extensio...
Dans le cadre du stockage des déchets nucléaires en couche géologique profonde (projet Cigéo), il est nécessaire de pouvoir prédire l'écoulement des radionucléides sous forme ionique dans des milieux poreux chargés tels que l'argile. Les matériaux argileux sont complexes et il est difficile de connaître leur structure, surtout à l'échelle nanoscopi...

Electrotransfer is a method by which molecules can be introduced into living cells via plasma membrane electropermeabilization. Here, we show that electropermeabilization affects the lateral mobility of Rae-1, a GPi anchored protein. Our results suggest that 10–20 % of the membrane surface is occupied by defects or pores and that these structures p...

•Short electric field pulse may induce single pores in a lipid membranes.•Pores may reseal or growing leading to irreversible rupture.•The kinetic of rupture is determined by viscosity leading an exponential pore growth.•Fast rupture is limited by inertia and is linear in time.

This work investigates novel hybrid sorbent materials based on ionic liquid (IL) modified porous silica for CO2 capture, aiming to tackle the limitations of the high viscosity of ionic liquids and to improve the selectivity of porous materials. Phosphonium based ionic liquids were covalently attached onto the surface of bare silica. CO2 adsorption ...

Diatoms are unicellular algae that synthesize cell wall with silica that has highly ornate features on the nano to microscale. The porous silica nanoparticulate structure of three marine centric and one pennate diatoms namely, Coscinodiscus concinnus, Coscinodiscus sp., Odontella mobiliensis and Navicula directa were investigated by Field Emission ...

A number of plasma membrane progestin receptors linked to non-genomic events have been identified. These include: (1) α1-subunit of the Na(+)/K(+)-ATPase (ATP1A1), (2) progestin binding PAQR proteins, (3) membrane progestin receptor alpha (mPRα), (4) progesterone receptor MAPR proteins and (5) the association of nuclear receptor (PRB) with the plas...

The numerous pores in the basement membrane (BM) of the intestinal villi are essential for the communication of enterocytes with cells in the lamina propria, an important mechanism for the induction of intestinal immune responses. The intestinal epithelial barrier is affected by the mycotoxin deoxynivalenol (DON) from both the apical (luminal) and ...
