Comparison of drug release from liquid crystalline monoolein dispersions and solid lipid nanoparticles using a flow cytometric technique.

Acta pharmaceutica Sinica. B

Dawoud MZ, Nasr M.
PMID: 27006901
Acta Pharm Sin B. 2016 Mar;6(2):163-9. doi: 10.1016/j.apsb.2016.01.004. Epub 2016 Jan 25.

Colloidal lipid particles such as solid lipid nanoparticles and liquid crystalline nanoparticles have great opportunities as drug carriers especially for lipophilic drugs intended for intravenous administration. In order to evaluate drug release from these nanoparticles and determine their behavior...

Novel agrochemical conjugates with self-assembling behaviour.

HYPOTHESIS: That conjugation of agrichemicals to pro-assembly hydrophobic moieties will enable enhanced compatibility and loading with host lyotropic liquid crystalline carrier matrix, and potentially self-assemble in their own right in aqueous environments.EXPERIMENTS: A series of lipid-like agrochemical-conjugates were synthesized...

J Phys Chem Lett. 2013 Jun 06;4(11):1959-64. doi: 10.1021/jz400857z. Epub 2013 May 28.

Structural changes occurring on a millisecond time scale during uptake of DNA by cationic lipid nanocarriers are monitored by time-resolved small-angle X-ray scattering (SAXS) coupled to a rapid-mixing stopped-flow technique. Nanoparticles (NPs) of nanochannel organization are formed by PEGylation,...

Heat-induced interfacial aggregation of a whey protein isolate (WPI) with a high content of beta-lactoglobulin (>92%), previously adsorbed at the oil-water interface, was studied by means of interfacial dynamic characteristics performed in an automatic drop tensiometer. Protein concentration in...

Effect of wheat bran and wheat germ on the intestinal uptake of oleic acid, monoolein, and cholesterol in the rat.

The effects of fiber-rich wheat bran and wheat germ on the intestinal absorption of dietary cholesterol, free fatty acids, and monoglycerides were studied. Rats were given a test meal containing [(14)C]oleic acid, [(14)C]monoolein, and [(3)H]cholesterol. After a 1-hour digestion...

Effect of sodium diclofenac loads on mesophase components and structure.

We studied the effect of a model electrolytic drug on intermolecular interactions, conformational changes, and phase transitions in structured discontinuous cubic QL lyotropic liquid crystals. These changes were due to competition with hydration of the lipid headgroups. Structural changes...

The default lipid for the bulk of the crystallogenesis studies performed to date using the cubic mesophase method is monoolein. There is no good reason however, why this 18-carbon, cis-monounsaturated monoacylglycerol should be the preferred lipid for all target...

Large PAMAM Dendron Induces Formation of Unusual P4.

Compact macromolecular dendrons have previously been shown to induce the formation of discontinuous inverse micellar assemblies with Fd3 m symmetry in monoolein/water systems. Here, we demonstrate that a large PAMAM dendron (G5: fifth generation) induces the formation of a...
