A perfluorochemical blood substitute emulsified with Pluronic F-68 has been shown to improve the filterability of deoxygenated sickle red cells. We questioned whether some of the effect was independent of oxygen loading and studied the influence of Fluosol DA (Green Cross, Osaka, Japan) and Pluronic on the rheology and adhesion of sickle red cells saturated with oxygen and carbon monoxide. A 5-...

Poloxamer block copolymers have been studied in multiple applications as drug delivery systems (DDS). These A-B-A amphiphilic block copolymers up-regulate the expression of selected genes in cells and alter genetic responses to antineoplastic agents in cancer. One example is poloxamer 188, also known as pluronic F68, which may be promising as a carrier in DDS. To clarify the possible mechanisti...

BACKGROUND Electrospinning is an easy and effective technique to produce submicron fibers possessing a range of attractive characteristics such as interconnected porous structures similar to natural ECM and good resilience to movement. Rapid and efficient cell attachment to nanofibrous matrices is a necessary prerequisite in tissue engineering. Thus, the aim of this study is to evaluate poly(ε-...

pluronic/bile salt/phospholipid mixed micelles (pluronic/bs/ps-mm) drug carrier system for solubilization hydrophobic drugs was developed. a typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. five pluronics, f68, f88, f98, f108, and f127 with different ppo chain length were studied. cmc data and solubilization capacities w...

Abstract Mixed micellar systems have been tried with the aim of achieving higher solubility drugs compared to single systems. Hydrophobic-hydrophilic mixed used for above purpose drug ciprofloxacin in past. In present study, a hydrophilic-hydrophilic binary system comprising pluronic copolymers F127 and L64 has studied its effect on solubilization Ciprofloxacin. The solutions two individual the...

Multidrug resistance (MDR) in tumor cells is a significant obstacle to the success of chemotherapy in many cancers. The purpose of this research is to test the possibility of docetaxel-loaded poly (e-caprolactone)/Pluronic F68 (PCL/Pluronic F68) nanoparticles to overcome MDR in docetaxel-resistance human breast cancer cell line. Docetaxel-loaded nanoparticles were prepared by modified solvent d...

A Pluronic polymeric mixed micelle delivery system was developed in this study by using Pluronic P105 and F127 block copolymers to encapsulate the antitumor compound, methotrexate (MTX). The MTX-loaded Pluronic P105/F127 mixed micelle exhibited the spherical shape with about 22 nm in diameter, high encapsulation efficiency (about 85%) and pH-dependent in vitro drug release. In this study, A-549...

Pluronic-PAA, a thermogelling copolymer composed of side chains of poly(acrylic acid) (PAA) grafted onto a backbone of Pluronic copolymer, is of interest as a vehicle for the controlled release of compounds. An important feature of such a vehicle is its bioadhesive/mucoadhesive properties, which in the case of Pluronic-PAA are significant due to the presence of the PAA side chains. An atomic fo...

The aim of the present study was to formulate and evaluate nystatin containing thermosensitive mucoadhesive gel for vaginal drug delivery to achieve prolonging the residence time, sustained drug release, enhancing efficacy, decreasing recurrence, and increasing patient compliance in the treatment for vaginal candidiasis. Here nystatin (1%) as a model drug. A 3 full factorial design was employed...
