Fatty acid-free albumin has been the standard carrier for intravenous infusion of fatty acids to study in vivo lipid metabolism. However, subjects can have adverse reactions to infusion of albumin. We sought an alternative to albumin as a carrier for intravenous infusion of fatty acids, using the pig as a model. Cyclodextrins are naturally occurring water-soluble molecules that can serve as car...

The inclusion complexation behavior of azadirachtin with several cyclodextrins and their methylated derivatives has been investigated in both solution and the solid state by means of XRD, TG-DTA, DSC, NMR, and UV-vis spectroscopy. The results show that the water solubility of azadirachtin was obviously increased after resulting inclusion complex with cyclodextrins. Typically, beta-cyclodextrin ...

the aim of this study was to design orally disintegrating tablets of olanzapine and to complex olanzapine with 2-hydroxypropyl-β- cyclodextrin with special emphasis on disintegration and dissolution studies. phase solubility studies demonstrated the formation of 1:1 molar inclusion complex by kneading method. tablets were prepared by using superdisintegrants namely, sodium starch glycolate, cro...

This study presents improvement in solubility and dissolution rate of valsartan (VAL) using β-cyclodextrin (βCD) and hydroxypropyl-β-cyclodextrin (HP-βCD). Formation and characterization of solid inclusion complexes were investigated by DSC, FTIR, SEM, HNMR and in-vitro dissolution studies. Preparation method influenced physical properties of binary mixtures. Inclusion complexes obtained by co-...

From the effect of β-cyclodextrin and hydroxypropyl-β-cyclodextrin on the UVvisible and fluorescence spectra of carbaryl and carbofuran, the values of association constants were determined. The ratio of the fluorescence quantum yields for the bound and free substrates indicated an enhanced fluorimetric method of detection.

BACKGROUND/AIMS F508delCFTR-, but not wtCFTR-, expressing fibroblasts resemble Niemann Pick type C cells in the massive intracellular accumulation of free cholesterol. The recruitment and activation of F508delCFTR by cholesterol depletion was studied. METHODS Filipin staining, forskolin-stimulated anion efflux and FITC-dextran uptake were studied in control cells and fibroblasts treated with ...

Water-based propolis extracts usually contain up to 10-fold lower quantities of active ingredients due poor solubility in water bioactive compounds when compared with ethanol-based extracts. Since are limited use, water-based preferred nowadays. The application alternative extraction techniques should be evaluated improve efficiency. Aqueous were prepared using purified and propylene glycol, 2-...
