Release Kinetics of Encapsulated Herbal Antioxidants during Gelation Process

Biocompatible Coating of Encapsulated Cells Using Ionotropic Gelation

The technique of immunoisolated transplantation has seen in the last twenty years improvements in biocompatibility, long term stability and methods for avoidance of fibrosis in alginate capsules. However, two major problems are not yet solved: living cellular material that is not centered in the capsule is not properly protected from the hosts' immune system and the total transplant volume need...

Kinetics and thermal behaviour of the structure formation process in HMP/sucrose gelation.

The concentration and temperature dependence of the gelation kinetics of high-methoxyl pectin (HMP; 60% sucrose, pH 3) was investigated using measurements of small-amplitude oscillatory shear. The rate of gelation close to the gel point can be described as a second-order rate process using the kinetic model of Ross-Murphy (Carbohydr. Polym. 1991, 14, 281) and a critical exponent close to that p...

Herbal Antioxidants as Rejuvenators in Alternative Medicine

Preparation, Characterization and Release Kinetics of Encapsulated Lithium Carbonate into Carnauba Wax Microspheres

The objective of the present study was to minimise the unwanted side effects of lithium carbonate (LC) drug by kinetic control of drug release, LC was entrapped into gastro resistant, biodegradable carnauba wax microspheres using meltable emulsified dispersion cooling induced solidification technique utilizing a wetting agent. Solid, discrete, reproducible free flowing microspheres were prepare...
