De novo identification of lipid II binding lipopeptides with antibacterial activity against vancomycin-resistant bacteria

Creative strategies for identifying new antibiotics are essential to addressing the looming threat of a post-antibiotic era. We here report the use of a targeted peptide phage display screen as a means of generating novel antimicrobial lipopeptides. Specif ...

Cellular uptake and biocompatibility of bismuth ferrite harmonic advanced nanoparticles

Sandrine Gerber, Solène Marcelle Françoise Marie Passemard, Jean-Pierre Wolf, Stephanie Hwu, Luigi Bonacina, Daniel Rytz

Bismuth Ferrite (BFO) nanoparticles (BFO-NP) display interesting optical (nonlinear response) and magnetic properties which make them amenable for bio-oriented diagnostic applications as intra- and extra membrane contrast agents. Due to the relatively rece ...

Flow simulation and hemolysis modeling for a blood centrifuge device

Mark Sawley, Michel Deville, Patric Hagmann

A common blood separation technique is to accelerate the sedimentation of blood constituents by centrifugation and then collect these constituents separately. When subjected to conditions of excessive stress, hemolysis can however occur, whereby the membra ...

Association of hemolytic activity of Pseudomonas entomophila, a versatile soil bacterium, with cyclic lipopeptide production

Bruno Lemaitre, Christoph Keel

Pseudomonas entomophila is an entomopathogenic bacterium that is able to infect and kill Drosophila melanogaster upon ingestion. Its genome sequence suggests that it is a versatile soil bacterium closely related to Pseudomonas putida. The GacS/GacA two-com ...

Shear stress and cyclic circumferential stretch, but not pressure, alter connexin43 expression in endothelial cells

Nikolaos Stergiopoulos, Paolo Silacci

Hemodynamic forces play a critical role in atherogenesis, as evidenced by the focal pattern of development of atherosclerotic lesions. Whereas disturbed flow in the branches and curved regions of large arteries is proatherogenic, laminar flow in the straig ...

Conversion of a transmembrane to a water-soluble protein complex by a single point mutation

Françoise Gisou van der Goot Grunberg

Proteins exist in one of two generally incompatible states: either membrane associated or soluble. Pore-forming proteins are exceptional because they are synthesized as a water-soluble molecule but end up being located in the membrane -- that is, they are ...

Identification of residues critical for toxicity in Clostridium perfringens phospholipase C, the key toxin in gas gangrene

Stewart Cole

Clostridium perfringens phospholipase C (PLC), also called alpha-toxin, is the major virulence factor in the pathogenesis of gas gangrene. The toxic activities of genetically engineered alpha-toxin variants harboring single amino-acid substitutions in thre ...

Pulse pressure method and the area method for the estimation of total arterial compliance in dogs: sensitivity to wave reflection intensity

Nikolaos Stergiopoulos, Patrick Segers

We estimated total arterial compliance (C) in eight anesthetized mongrel dogs with (i) the area method (AM), (ii) the pulse pressure method (PPM), and (iii) the stroke volume-to-pulse pressure ratio (SV/PP). Average compliance was C(AM)=1.1+/-0.73 ml mm Hg ...

Complex regulation of transferrin receptors during erythropoietin-induced differentiation of J2E erythroid cells--elevated transcription and mRNA stabilisation produce only a modest rise in protein content

Lukas Kühn

The regulation of transferrin-receptor synthesis was studied in J2E erythroid cells induced to differentiate with erythropoietin. Nuclear run-on assays demonstrated that transcription of the transferrin-receptor gene rose markedly after erythropoietin trea ...

Use of site-directed mutagenesis to probe structure-function relationships of alpha-toxin from Clostridium perfringens.

Stewart Cole

The NH2-terminal domain of the alpha-toxin of Clostridium perfringens is highly homologous to the complete phospholipase C from Bacillus cereus (PC-PLC), for which a high-resolution crystal structure is available. This structural information was used as th ...
