Controlled drug release from a spheroidal matrix
(ELSEVIER SCIENCE BV, 2019-01-01)
Drug transport through a spheroidal matrix was studied using Fick's second law of diffusion in spherical coordinates. The prolate spheroid-shaped geometry was described by a small angular deformation applied at the surface ...
Multilayered electrospun nanofibrous scaffolds for tailored controlled release of embelin
(Taylor & Francis, 2018-01)
Polymeric electrospun meshes are highly attractive as versatile platforms for numerous biomedical applications, tissue engineering, biosensors, and controlled release of bioactive agents. Herein, we describe the preparation ...
Chitin nanowhiskers as alternative antimicrobial controlled release carriers
(Royal Society of Chemistry, 2015-01)
Antimicrobial finishings protect users from pathogenic and odor-generating microorganisms, which are of medical and hygiene concerns. Controlled release is a useful approach to obtain antimicrobial finishings in several ...
Films based on the biopolymer poly(3-hydroxybutyrate) as platforms for the controlled release of dexamethasone
(Elsevier, 2019-07)
Controlled drug delivery aims to achieve an effective drug concentration in the action site for a desired period of time, while minimizing side effects. In this contribution, biodegradable poly(3-hydroxybutyrate) films ...
Controlled release and antioxidant activity of chitosan or its glucosamine water-soluble derivative microcapsules loaded with quercetin
(Elsevier Science, 2018-06-13)
The controlled release and antioxidant properties of the flavonoid quercetin (Qr) incorporated into crosslinked microcapsules using chitosan (Ch) or its derivative modified with glucosamine by Maillard reaction (GACh) as ...
Controlled release systems of natural phenolic antioxidants encapsulated inside biocompatible hydrogels
(Elsevier Science, 2020-11)
Encapsulated systems of antioxidants control the bioavailability in foods, enhancing and conserving their quality. Biocompatible hydrogels based on poly-(N-isopropylacrylamide) (PNIPAM) and copolymers, crosslinked with ...
Interaction between substance P and TRH in the control of prolactin release
(BioScientifica, 2000-02)
Substance P (SP) may participate as a paracrine and/or autocrine factor in the regulation of anterior pituitary function. This project studied the effect of TRH on SP content and release from anterior pituitary and the ...
One-dimensional drug release from finite Menger sponges: In silico simulation
(Pergamon-Elsevier Science Ltd, 2009-12)
The purpose of this work was to evaluate the consequences of the spatial distribution of components in pharmaceutical matrices type Menger sponge on the drug release kinetic from this kind of platforms by means of Monte ...
Chitosan/Starch Matrices Prepared by Ionotropic Gelation: Rheological Characterization, Swelling Behavior and Potassium Nitrate Release Kinetics
(Springer/Plenum Publishers, 2020-06)
A controlled-release fertilizer made of biodegradable beads prepared with neat chitosan or chitosan/starch blends loaded with potassium nitrate was obtained using an ionic cross-linking process. This study looks at the ...
