The aim of this work was to produce and characterize cetyl palmitate-based solid lipid nanoparticles (SLN) containing insulin, and to evaluate the potential of these colloidal carriers for oral administration. SLN were prepared by a modified solvent emulsification-evaporation method based on a w/o/w double emulsion. The particle size, zeta potential and association efficiency of unloaded and in...

Nanocrystalline Zinc Oxide (ZnO) powders with different morphology have been successfully synthesized by using different surfactants such as Cetyl Trimethyl Ammonium Bromide (CTAB), Sodium Dodecyl Sulphate (SDS), and Tri Ethanol Amine (TEA) via hydrothermal method. The products were characterized by means of powder X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electr...

background: alcohol is a potent teratogen and alcohol use in pregnancy and the periconception period can cause many complications in mother, fetus and neonate.  discussion: alcohol in the mother's blood passes through the placenta to the baby through the umbilical cord. drinking alcohol during pregnancy can cause miscarriage, stillbirth, and a range of lifelong disorders. alcohol-related birth ...

To study the effects of incorporating a further crosslinking agent and novel surfactant on water absorption behaviour experimental VPS impression materials. Part 1: The uptake Aquasil-Ultra-Monophase (AqM) was studied gravimetrically in three media (DW, 1%NaOCl Perform ID), at 23 °C 37 °C, over period one four-months (n = 5) to gain information long-term immersion. 2: Five materials were formul...

In recent years, several studies have shown that the use of solid lipid nanoparticles (SLN) as a colloidal drug delivery system was more advantageous than emulsions, liposomes and polymeric nanoparticles. SLNs numerous advantages different nanosystems rule out many their drawbacks. Despite SLNs, translation from preclinical formulation to industrial scale-up is limited. order provide reproducib...

In recent days Zinc oxide (ZnO) attracted much interest due to its versatibility and size dependent opto-electronic properties. ZnO flake structures have been hydrothermally synthesized in the reaction of aqueous solution of cetyl trimethyl ammonium bromide (CTAB) and NaOH at 373.15 K. It was found that, the volume of added ammonia, surfactant (CTAB), and mixed solvent play crucial roles in mor...

Some N-alkyl pia-hydroxy styryl pyridinium halides, the alkyl moieties being methyl, hexyl and decyl, have been synthesised and the acid dissociation constants of these compounds in aqueous and surfactant solutions have been determined using spectrophotometric method . The alkyl chain does not have any substantial effect on the pKa values in aqueous and cationic surfactant (cetyl trimethylammon...
