Rapid kinetic studies of SH oxidation-induced calcium release from sarcoplasmic reticulum vesicles
(Academic Press Inc., 1997)
We studied the kinetics of calcium release induced by SH oxidation in triads isolated from frog and rabbit skeletal muscle by measuring calcium fluxes by a fast filtration method. In both species SH oxidation induced release ...
Development and in vitro evaluation of lyotropic liquid crystals for the controlled release of dexamethasone
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 ...
Gold nanoparticles for photothermally controlled drug release
(Future Medicine Ltd., 2014)
© 2014 Future Medicine Ltd. In this article, we describe how nanoparticles work in photothermally triggered drug delivery, starting with a description of the plasmon resonance and the photothermal effect, and how this is ...
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) ...
Exploring the influence of Diels–Alder linker length on photothermal molecule release from gold nanorods
(Elsevier B.V., 2018)
© 2018 Elsevier B.V. We studied the photothermal release of carboxyfluorescein (CF) linked to the gold surface of gold nanorods (GNRs) by two Diels–Alder adducts of different lengths (n = 4 and n = 9). The functionalized ...
Development of a mechanism and an accurate and simple mathematical model for the description of drug release: Application to a relevant example of acetazolamide-controlled release from a bio-inspired elastin-based hydrogel
(Elsevier Science, 2016-04)
Transversality between mathematical modeling, pharmacology, and materials science is essential in order to achieve controlled-release systems with advanced properties. In this regard, the area of biomaterials provides a ...
Preparation and characterization of poly(e-caprolactone) nanospheres containing the local anesthetic lidocaine
Thermal and morphological characterization of highly porous nanocomposites for possible application in potassium controlled release
The use of fertilizer and water availability are essential factors limiting the agricultural production. The controlled release technology is very promising because it allows the maintenance of fertilizer concentrations ...
Development and In Vitro Evaluation of Surfactant Systems for Controlled Release of Zidovudine
(John Wiley & Sons Inc, 2010-05-01)
The development of a controlled-release dosage form of zidovudine (AZT) is of crucial importance, in view of the pharmacokinetics of its toxic activity. A suitable drug delivery system could increase AZT bioavailability, ...
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. ...
