Colon-specific drug delivery systems have attracted increasing attention from the pharmaceutical industry due to their ability of treating intestinal bowel diseases (IBD), which represent a public health problem in several ...

The aim of this work was to perform the extraction and characterization of xylan from corn cobs and prepare xylan-based microcapsules. For that purpose, an alkaline extraction of xylan was carried out followed by the ...

Currently, studies in the area of polymeric microcapsules and nanocapsules and controlled release are considerably advanced. This work aims the study and development of microcapsules and nanocapsules from Chitosan/MDI, ...

Micro and nanoparticulate systems as drug delivery carriers have achieved successful therapeutic use by enhancing efficacy and reducing toxicity of potent drugs. The improvement of pharmaceutical grade polymers has allowed ...

This thesis was devoted to the development of innovative oral delivery systems for two different molecules. In the first part, microparticles (MPs) based on xylan and Eudragit® S- 100 were produced and used to encapsulate ...

Xylan is a biopolymer extracted from cell wall of vegetables, especially cereals, such as corn cobs. Because it is not degraded on the upper gastrointestinal tract, xylan has been explored by food industries in order to ...

Due to advantages such as low cost, lightweight, possibility of environmental protection and good mechanical properties when compared with fiberglass reinforcement materials, composites reinforced with natural fibers have ...

Enhanced oil recovery (EOR) processes were developed as a strategy to extend the productivity of mature reservoirs. Polymer flooding-based HPAM is the EOR process more implemented due to its relatively low cost and operational ...
