We investigated the pressure driven flow of concentrated colloidal dispersions in a converging channel geometry. Optical microscopy and image analysis were used to track tracer particles mixed into dispersions of sterically stabilized poly(methyl methacrylate) (PMMA) spheres. The dispersions were drawn into a round 0.5 mm capillary at one of two pump speeds (^ applied pressure): v1 1⁄4 0.245 ml...

in the present study solid dispersions of the antifungal drug ketoconazole were prepared with pluronic f-127 and pvp k-30 with an intention to improve its dissolution properties. investigations of the properties of the dispersions were performed using release studies, differential scanning calorimetery (dsc), x-ray powder diffraction (xrd) and fourier transform infrared (ftir). the results obta...

the importance of the use of activated charcoal tubes for sampling gases and vapors is very well-known. for producing these tubes in the country, their production started in the laboratory of the department of occupation al health using activated charcoal, polyurethane foam and glass wool and consequently two types of foamed and foamless tubes were produced. to investigate the quality of the ra...

In the present work an attempt has been made to increase the solubility and dissolution rate of lansprozole by formulating it as solid dispersions by lipid carriers such as compritol 888 ATO Phospholipon 90 H and Lipoid S100 by using Fusion method, Kneading method and solvent evaporation method. Further the solid dispersions were compressed as orodispersible tablets by using croscarmelloe sodiu...

We develop a strategy for preparing water-based dispersions of polymer/TiO₂ nanospheres that can be used to form composite materials applicable in various fields. The formed hybrid nanospheres are monodisperse and possess a hierarchical structure. It starts with the primary TiO₂ nanoparticles of about 5 nm, which first assemble to nanoclusters of about 30 nm and then are integrated into monomer...

Solid dispersions have been widely used to enhance the solubility of poorly water soluble drugs. In this study, solid dispersions of valsartan (VAL) with natural polymers such as hupu gum (HG), guar gum (GG) and xanthan gum (XG) were prepared by kneading technique in the weight ratios of 1:1,1:2,1:3 and1:4.The prepared solid dispersions were investigated by X-ray diffraction, infrared spectrosc...

Aim: To enhance the aqueous solubility of olanzapine by using the Solid dispersion technique. Solid dispersions of Olanzapine were prepared by the dispersion method using using PGS and SSG as carriers. Drug:carrier ratios such as 1:1, 1:2, 1:4, 1:6, 1:8 and 1:10 were tried for optimization. Characterization was done by phase solubility, in vitro release, saturation solubility, permeation, wetta...

BACKGROUND Successful wound healing depends on various factors, including exudate control, prevention of microbial contaminants, and moisture balance. We report two cases of managing burn wounds with SMARTPORE Technology polyurethane foam dressing. CASE PRESENTATION In Case 1, a 2-year-old Asian girl presented with a delayed (11 days) wound on her right leg. She sustained a thermal injury fro...

BACKGROUND Peripheral arterial catheters are widely used in the care of intensive care patients for continuous blood pressure monitoring and blood sampling, yet failure - from dislodgement, accidental removal, and complications of phlebitis, pain, occlusion and infection - is common. While appropriate methods of dressing and securement are required to reduce these complications that cause failu...
