PURPOSE To investigate histological features and biocompatibility of a latex biomembrane for bladder augmentation using a rabbit model. MATERIAL AND METHODS After a partial cystectomy, a patch of a non-vulcanized latex biomembrane (2x4 cm) was sewn to the bladder with 5/0 monofilament polydioxanone sulfate in a watertight manner. Groups of 5 animals were sacrificed at 15, 45 and 90 days after...

Acyclovir has been conjugated to the acyclic isoprenoid chain of squalene to form the squalenoyl-acyclovir prodrug. Its interaction with biomembrane models constituted by dimyristoylphosphatidylcholine (DMPC) monolayers has been studied by employing the Langmuir-Blodgett technique. The aim of the work was to gain information on the interaction of these compounds with phospholipid membranes. DMP...

We derive a biomembrane model consisting of a fluid enclosed by a lipid membrane. The membrane is characterized by its Canham-Helfrich energy (Willmore energy with area constraint) and acts as a boundary force on the Navier-Stokes system modeling an incompressible fluid. We give a concise description of the model and of the associated numerical scheme. We provide numerical simulations with emph...

Evidence is discussed for roles of cardiolipins in oxidative phosphorylation mechanisms that regulate State 4 respiration by returning ejected protons across and over bacterial and mitochondrial membrane phospholipids, and that regulate State 3 respiration through the relative contributions of proteins that transport protons, electrons and/or metabolites. The barrier properties of phospholipid ...

Lin et al. examined the effects of lipid chains attached to N-terminal antimicrobial peptides, a type membrane-active on their membrane activity and bioactivity. The impact lipidation varied depending original peptides' hydrophobicity. By altering peptide conformations affecting self-aggregation behaviours, changed peptide-biomembrane interaction, ultimately bioactivity (e329).

The dynamic behaviors of molecular assemblies at two immiscible liquid interfaces are intriguing topics in many fields of science and technology. However, it is generally difficult to investigate the dynamic behaviors of such molecular assemblies because of the buried nature of liquid/liquid interfaces. In the present paper, our recent investigations on dynamic behaviors of various molecular se...
