Fast and potent bactericidal membrane lytic activity of PaDBS1R1, a novel cationic antimicrobial peptide

Luz N Irazazabal, William F Porto, Isabel C.M. Fensterseifer, Eliane S.F. Alves, Carolina Matos, Antônio C.S. Menezes, Mário R Felício, Sónia Gonçalves, Nuno Santos, Suzana M Ribeiro, Vincent Humblot, Luciano M Lião, Ali Ladram, Octavio L Franco

Antimicrobial peptides (AMPs) are promising candidates for the development of future antibiotics. In an attempt to increase the efficacy of therapeutic AMPs, computer-based design methods appear as a reliable strategy. In this study, we evaluated the antimicrobial efficiency and mechanism of action…

Surface response methodology for the study of supported membrane formation.

C. Rossi, Elisabeth Briand, P. Parot, Michaël Odorico, Joël Chopineau

We report on the investigations of the formation of the tethered lipid bilayer by vesicle deposition on amine-functionalized surfaces. The tethered bilayer was created by the deposition of egg-PC vesicles containing 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-poly-(ethyleneglycol)-N-…

TOOTHMIMIC : enzyme-assisted mineralization for the design of biomimetic enamel, TOOTHMIMIC : minéralisation assistée par enzyme pour la conception d'émail biomimétique

Brittany Foley

Biomineralization is the intricately-regulated process by which living organisms form hierarchically ordered mineralized materials. In the human body, the hard tissues are formed of calcium phosphate mineral composites with unique architectures that provide unparalleledmaterial properties. While…, La biominéralisation est le processus complexe par lequel les organismes vivants forment des matériaux minéralisés hiérarchiquement organisés. Dans le corps humain, les tissus durs sont formés de composites minéraux de phosphate de calcium avec des architectures uniques qui fournissent des…

Silk Bionanocomposites for Organic Dye Absorption and Degradation

Cristina Belda Marín, Christophe Egles, Jessem Landoulsi, Erwann Guénin

Organic dyes are extensively used in the textile, paper and paint industries, among others. However, the lack of efficient treatment of disposals leads to the release of these toxic molecules into the environment, which has an enormous impact on living organisms. Dye absorption is the most common…

ZnFe2O4 pour des applications en photocatalyse hétérogène dans le visible, ZnFe2O4 for heterogeneous photocatalysis applications in the visible

Aya Jezzini

Ce travail de thèse concerne la dépollution des eaux en utilisant des mélanges très enrichis en ferrite de zinc et activés par de la lumière visible. Nos solides ont été testés pour deux réactions : 1) l’oxydation et décomposition d’un antibiotique, l’amoxyciline ou AMX très utilisée en médecine…, Our work is devoted to the water depollution by photocatalysis with mixtures enriched in Zn ferrites and under visible light. It concerns 1) Amoxicilin (AMX), as one of the pharmaceutical polluting molecule that can be found in water and may have a toxic effect. 2) Bacterium Staphylococcus…

Design de composites verts pour la dépollution des terres agricoles : expérience et théorie, Design of green composite for the decontamination of agricultural land : experimental and theoretical

Khaled El Adraa

Des matériaux verts biodégradables à base de Montmorillonite et de cystéine ont été préparés dans le but de co-adsorber des cations de métaux lourds et des polluants émergeants en combinant l’expérience et la théorie (calculs DFT). Les analyses thermiques différentielles ont permis d’estimer le…, Layered silicates like smectites are important soil components. Many works have been devoted to functionalize these materials in order to increase their chelating properties which may help retain heavy metals. It is well known that Cd2+, Hg2+, Pb2+, Co2+ and Zn2+ forms stable complexes with sulfur-…

Electron Transfer at the Metal Oxide/Electrolyte Interface: A Simple Methodology for Quantitative Kinetics Evaluation

Iban Azcarate, Cyrille Costentin, Christophe Méthivier, Christel Laberty-Robert, Alexis Grimaud

While quantitative models exist for measuring rate constants for electron exchange at the surface of semiconductors to or from redox couples in solution, their use is very limited for studying transition metal oxide electrodes. Taking advantage of the possibility of tuning the doping level of WO 3…
