Evaluation of the Drug Release Kinetics in Assembled Modular Systems Based on the Dome Matrix Technology
(John Wiley & Sons Inc, 2020-06-10)
Mathematical models are an important tool in pharmaceutical formulationsdevelopment, to evaluate in vitro and in vivo drug release processes and to optimize the design of new systems. Dome Matrix technology allows the ...
Release kinetics of rosemary (Rosmarinus officinalis) polyphenols from polyvinyl alcohol (PVA) electrospun nanofibers in several food simulants
(Elsevier Ltd, 2018-12)
Polyvinyl alcohol (PVA) electrospun mats with antioxidant activity (PVA/Ros) were obtained by incorporating rosemary extract (RE) into the electrospinning precursor solution. RE compounds interact with PVA, favoring the ...
Classical Antiferromagnetism in Kinetically Frustrated Electronic Models
(American Physical Society, 2014-05)
We study, by means of the density matrix renormalization group, the infinite U Hubbard model—with one hole doped away from half filling—in triangular and square lattices with frustrated hoppings, which invalidate Nagaoka’s ...
Rue and clove microspheres: antiamebic activity, hemocompatibility, and release kinetics
(Academia Nacional de Medicina venezolana., 2022)
Validation of kinetic modeling of progesterone release from polymeric membranes
(Shenyang Pharmaceutical University, 2018-01)
Mathematical modeling in drug release systems is fundamental in development and optimization of these systems, since it allows to predict drug release rates and to elucidate the physical transport mechanisms involved. In ...
Controlled release of antibiotics from photopolymerized hydrogels: Kinetics and microbiological studies
(Elsevier Science, 2019-09)
The development of convenient synthetic methods and improved materials for the production of high load-capacity and biocompatible drug delivery systems is a challenging task with important implications in health sciences. ...
N,N-Dimethylacrylamide Hydrogels for Controlled Drug Delivery. Influence of Network Structure and Drug Solubility on the Load and Release Mechanisms
(Planta Piloto de Ingeniería Química, 2019-08)
The aim of the present work was to synthesize sustained-release hydrogels based on N,N-dimethylacrylamide (DMA) to study the effect of the polymer matrix structure and the solubility of drugs on the load and release ...
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 ...
Highly Structured Polyvinyl Alcohol Porous Carriers: Tuning Inherent Stability and Release Kinetics in Water
(American Chemical Society, 2018-02)
Polyvinyl alcohol (PVA) porous carriers were prepared by means of ice templating of aqueous solutions containing of 90 kD and/or 16 kD PVA. The carriers were loaded with traces of a colored probe (methyl orange) to screen ...
Ciprofloxacin in Layered Double Hydroxides: Looking for the Best Synthesis Method
It is important to develop new methods of release to improve pharmacokinetic parameters of drugs, especially antibiotics, whose plasmatic concentration is determinant to ensure an effective treatment. Layered double ...
