There is increasing demand for reconstruction of glottal insufficiency. Several injection materials have been examined for this purpose, but all had limitations, such as poor long-term durability, migration from the injection site, inflammation, granuloma formation, and interference with vocal fold vibration due to viscoelastic mismatch. Here, we developed a novel injection material, consisting...
Pluronics with different structural compositions and properties are used for several applications, including drug delivery systems. We developed a binary mixing system with two Pluronics, L121/P123, as a nano-sized drug delivery carrier. The lamellar-forming Pluronic L121 (0.1 wt%) was incorporated with Pluronic P123 to produce nano-sized dispersions (in case of 0.1 and 0.5 wt% P123) with high ...
a major function of the enterocytes is absorption, processing, and export of dietary lipids into the lymphatic system. pluronic l-81 is a non-ionic hydrophobic surfactant, which specifically inhibits lipid absorption in the intestine when administered in vivo. this compound is therefore an attractive probe to perturb and investigate the molecular and intracellular events in chylomicron assembly...
Objective(s):Despite of wide range applications of polymeric nanoparticles in protein delivery, there are some problems for the field of protein entrapment, initial burst and controlled release profile. Materials and Methods: In this study, we investigated the influence of some changes in PLGA nanoparticles formulation to improve the initial and controlled release profile. Selected parameters ...
In order to apply curcumin as a photosensitizer in photodynamic therapy (PDT) one needs a formulation that can solubilize and stabilize the compound. Pluronics® (Pluronic) are reported to both solubilize and stabilize curcumin against hydrolytic degradation. The aim of the present work was therefore to investigate the influence of Pluronic formulation on the photocytotoxicity of curcumin. Inter...
Novel cationic pentablock copolymers based on poly(2-diethylaminoethylmethacrylate) (PDEAEM) and Pluronic F127 were evaluated as non-viral gene delivery vectors from a physiochemical point of view for stability and transfection efficiency in complete growth media. A novel strategy was introduced to sterically stabilize the polyplexes of such Pluronic-based cationic polymers against aggregation ...
The choline-hexanoate IL increases the biphasic region of Pluronic solutions.
Statement of Purpose: Various nanoparticle systems with a long blood circulation time and a high tumor accumulation have been reported for cancer diagnosis and treatment based on their EPR (enhanced permeability and retention) effect [1,2]. Here, we prepared several Pluronic-based nano-carriers attached with an NIR dye, and characterized their cellular uptake and in-vivo tumor targeting efficie...
Background and Objectives: Rapamycin has been shown to inhibit the vascular smooth muscle cell migration and proliferation that contributes to neointimal formation. We investigated whether the perivascular delivery of rapamycin in Pluronic gel could inhibit neointimal hyperplasia in a rat carotid artery model, and we tested the usefulness of carotid arteriography. Materials and Methods: To asse...
Poloxamer micelles promise safety and efficacy for many water insoluble drugs. Chrysin has been reported to have anticancer, anti-inflammatory, antioxidant, and anti-aromatase activities but its water insoluble properties limit its pharmaceutical application. In the present study, chrysin loaded poloxamer micelles were developed. Two types of poloxamers, Pluronic F-68 and Pluronic F-127 were co...
