The paper is focused on the formation of calcium phosphate nanoparticles (CP) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, anionic surfactantant and cosurfactant, in the presence of anionic and cationic polyelectrolyte. It is shown that polyelectrolyte, can be incorporated into the individual inverse microemulsion droplets. The ...

this trial was conducted to investigate the effect of phospholipid on blood and serum factors in rainbow trout (oncorhynchus mykiss) fed fat powder. phospholipid in two levels was added to 20 percent fat based on diet including 50% fat powder. control diet contained fish oil instead of fat powder and was lack of phospholipid. 150 juvenile rainbow trout with initial mean weight of 27.45±1.88g st...

Thermodynamic features related to preparation and use of self-assemblies formed between multilamellar and unilamellar zwitterionic liposomes and polynucleotides with various conformation and sizes are presented. The divalent metal cation or surfactant-induced adsorption, aggregation and adhesion between single- and double-stranded polyribonucleotides and phosphatidylcholine vesicles was followe...

The paper is focused on the formation of hydroxyapatite nanoparticles (HAp) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of Na-polyacrylate (PAA) as an anionic polyelectrolyte. It is shown that PAA, can be incorporated into the individual inverse microemulsion droplets. The m...

Nanosized hydroxyapatite (HA) powders have been synthesized by an inverse microemulsion system using cyclohexane, an anionic surfactant and aqueous solutions of calcium nitrate tetrahydrate and biammonium hydrogen phosphate in the presence of anionic and caionic polyelectrolyte with the inducement of ultrasound irradiation. Prepared HA in presence of anionic polyelectrolyte has a different morp...

The surface charge of isolated apolipoprotein A-I, apo-A-II, apo-C-II, and apo-C-III2 as well as of liposomes from synthetic highly purified phospholipids and isolated very low density lipoprotein (VLDL) particles from different donors (n = 35) was determined by polyelectrolyte titration. The particle size of apolipoproteins was evaluated from their molecular weight and specific volume, while t...

Chitosan (CS) and alginate (Alg) are complementary in their membrane performance, but the combination of them is normally difcult to use due to their different solubilities. Layer-by-Layer deposition appears to be an effective method for improving the separation efciency of a composite membrane. In this work, the polyelectrolyte multilayer composite membranes (PEMCMs) wer...

Immunostimulating reconstituted influenza virosomes (IRIVs) are liposomes with functional viral envelope glycoproteins: influenza virus hemagglutinin (HA) and neuraminidase intercalated in the phospholipid bilayer. Here we address the fusion of IRIVs to artificial supported lipid membranes assembled on polyelectrolyte multilayers on both colloidal particles and planar substrates. The R18 assay ...
