We have investigated and modeled the effect of interaction among magnetic particles and the magnitude and duration of external applied magnetic field on Brownian relaxation in a colloidal suspension. In the case of interacting magnetic particles, Brownian relaxation depends on the interparticle dipole-dipole interaction, which slows down the overall Brownian relaxation process of magnetic parti...

This paper outlines a complete and self-consistent cell model theory of the electrokinetics of dense spherical colloidal suspensions for general electrolyte composition, frequency of applied field, zeta potential, and particle size. The standard electrokinetic equations, first introduced for any given particle configuration, are made tractable to computation by averaging over particle configura...

Nanospheres of poly(methacrylic acid-grafted-poly(ethylene glycol)) were prepared by solution/precipitation polymerization. As colloidal drug delivery carriers, they present unique properties that render them promising candidates for oral protein delivery. The polymerization was carried out in water and the resulting suspension was freeze-dried. As with many colloidal systems, the freeze-dried ...

to evaluate the physical and chemical stability of a suspension of mycophenolate mofetil (mmf) prepared in the hospital from commercially available mmf capsules and tablets. extemporaneous pharmacy was used as a feasible method in this experimental study to prepare suspension form of mmf. suspension formulations were prepared from both tablets and capsules forms of mmf. thereafter the stability...

BACKGROUND Epidural injection of corticosteroids is a commonly used treatment for radicular pain. However, the benefits are often short lived, and repeated injections are often limited secondary to concerns of side effects from cumulative steroid doses. In addition, rare, catastrophic complications, including brain and spinal cord embolic infarcts have been attributed to particulate steroid inj...
