Development and in vitro evaluation of lyotropic liquid crystals for the controlled release of dexamethasone
(2017-08-02)
In this study, amphiphilic polymers were investigated as biomaterials that can control dexamethasone (DXM) release. Such materials present interfacial properties in the presence of water and an oily phase that can result ...
Alginate-Based Delivery Systems for Bevacizumab Local Therapy: In Vitro Structural Features and Release Properties
(2019-04-01)
Alginate-based polyelectrolyte complexes (PECs) and hydrogel were engineered as platforms for local bevacizumab (BVZ) therapy. This study provides deep comprehension on the microstructures of such systems, and their ...
Controlled release system for ametryn using polymer microspheres: Preparation, characterization and release kinetics in water
(Elsevier B.V., 2011-02-28)
The purpose of this work was to develop a modified release system for the herbicide ametryn by encapsulating the active substance in biodegradable polymer microparticles produced using the polymers poly(hydroxybutyrate) ...

Modeling a system of phosphated cross-linked high amylose for controlled drug release. Part 2: Physical parameters, cross-linking degrees and drug delivery relationships
(Elsevier B.V., 2009-04-17)
High amylose cross-linked to different degrees with sodium trimetaphosphate by varying base strength (2% or 4%) and contact time (0.5-4 h) was evaluated as non-compacted systems for sodium diclophenac controlled release. ...

Polysaccharides as safer release systems for agrochemicals
(Springer, 2015-01-01)
Agrochemicals are used to improve the production of crops. Conventional formulations of agrochemicals can contaminate the environment, in particular in the case of intensive cropping. Hence, there is a need for controlled-release ...
Poly(epsilon-caprolactone)nanocapsules as carrier systems for herbicides: Physico-chemical characterization and genotoxicity evaluation
(Elsevier B.V., 2012-09-15)
The toxicity of herbicides used in agriculture is influenced by their chemical stability, solubility, bioavailability, photodecomposition, and soil sorption. Possible solutions designed to minimize toxicity include the ...
Insulin-Loaded Poly(epsilon-Caprolactone) Nanoparticles: Efficient, Sustained and Safe Insulin Delivery System
(Amer Scientific PublishersValenciaEUA, 2013)
The controlled release of antibiotic by hydroxyapatite: Anionic collagen composites
(Blackwell Science, 1998-03-01)
Major problems with the treatment of osteomyelitis are associated with poor antibiotic distribution at the site of infection due to limited blood circulation to the skeletal tissue. Improved treatment procedures have been ...
