The membrane binding and model lipid raft interaction of synthetic peptides derived from the caveolin scaffolding domain (CSD) of the protein caveolin-1 have been investigated. CSD peptides bind preferentially to liquid-disordered domains in model lipid bilayers composed of cholesterol and an equimolar ratio of dioleoylphosphatidylcholine (DOPC) and brain sphingomyelin. Three caveolin-1 peptide...
The specific and selective detection of Salmonella typhymurium based on the use of a polyclonal antibody immobilized by the Langmuir-Blodgett method on the surface of a quartz crystal acoustic wave device was demonstrated in liquid samples. These biosensors were selective to S. typhymurium in the presence of large concentrations of Escherichia coli O157:H7. They were also specific to S. typhymu...
A revised water model intended for use in condensed phase simulations in the framework of the self consistent polarizable ion tight binding theory is constructed. The model is applied to water monomer, dimer, hexamers, ice, and liquid, where it demonstrates good agreement with theoretical results obtained by more accurate methods, such as DFT and CCSD(T), and with experiment. In particular, the...
Innate immunity relies upon the ability of a variety of recognition molecules to sense pathogens through conserved molecular signatures that are often carbohydrates. Ficolins are oligomeric proteins assembled from collagen-like stalks and fibrinogen-like domains that have the ability to sense these molecular patterns on both pathogens and apoptotic cell surfaces. Three ficolins, termed L, H and...
The current wound-healing collagen mimetic peptides (CMPs) have limitations such as poor membrane permeability and protease susceptibility. Herein, the solid-phase peptide synthesis of CMPs containing integrin binding motif GFOGER is reported. sequences also consist lipophilic moieties (adamantane palmitic acid) for improved different collagen-inducing tripeptides, namely, Thr-Thr-Lys (TTK), Gl...
water contamination due to the wide variety of pesticides used in agriculture is a global environmental pollution problem. in order to reach at sub-î¼gl-1 levels of detection, an efficient extraction technique is required. a simple, fast and economical method, dispersive liquid-liquid micro extraction (dllme), followed by gas chromatography-mass spectrometry was assessed for determining endosul...
a very simple, rapid and sensitive dispersive liquid-liquid microextraction (dllme) followed by gas chromatography and flame ionization detection (gc-fid) was developed for the determination of phenol and carvacrol in honey samples. a mixture of 100 µl dichloromethane (extraction solvent) and 0.5 ml acetonitrile (disperser solvent) was rapidly injected into sample solution. thereby a cloudy sol...
an efficient dispersive liquid-liquid microextraction using tetraalkylammonium bromide coated silver nanoparticles (dllme-agnps) prepared in chloroform has been successfully applied as electrostatic affinity probes to the microextraction and preconcentration of terazosin prior to spectrofluorimetry analysis. this technique is based on a ternary system of solvents, where appropriate amount of mi...
