Polyesters are extensively used in drug delivery because of their controllable biodegradation properties and perceived favorable cytocompatibility. However, new ester-based materials are continually being sought which can be produced from readily accessible monomers, which can be tuned for drug encapsulation and which retain good cellular compatibilities. In this study, 5 polyesters of similar ...

Xerosis is a common skin condition as well key aspect of number diseases associated to hereditary and acquired conditions. The objective this study was formulate evaluate the pluronic lecithin organogel containing natural moisturizing agents for topical application. Different formulations organogels were prepared by using Pluronic F127, Lecithin, Vitamin E, Aloe vera, water, sorbic acid, potass...

Polyethylenimine (PEI) is considered to be a promising non-viral gene delivery vector. To solve the toxicity versus efficacy and tumor-targeting challenges of PEI used as gene delivery vector, we constructed a novel non-viral vector DR5-TAT-modified Pluronic-PEI (Pluronic-PEI-DR5-TAT), which was based on the attachment of low-molecular-weight polyethylenimine (LMW-PEI) to the amphiphilic polyme...

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...

Gamma irradiation was tested as a method for sterilization of pluronic F-127 gel to be used for ocular delivery of ciprofloxacin (CFX). The effect of gamma irradiation on the properties of pluronic gels was studied at different irradiation doses and pluronic copolymer concentrations. The flow of pluronic gels of different concentrations was non-Newtonian with thixotropic pseudoplastic propertie...

Elevated red blood cell (RBC) aggregation increases low-shear blood viscosity and is closely related to several pathophysiological diseases such as atherosclerosis, thrombosis, diabetes, hypertension, cancer, and hereditary chronic hemolytic conditions. Non-ionic linear polymers such as poly(ethylene glycol) (PEG) and Pluronic F68 have shown inhibitory effects against RBC aggregation. However, ...

This article provides a brief and basic discussion of Pluronic lecithin organogel to include its history, its components, its mechanism of action, the range of active pharmacological agents that can and cannot be incorporated into a Pluronic lecithin organogel, as well as important information for those pharmacists who compound Pluronic lecithin organogel.

This study was carried out to assess the feasibility of human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) in articular cartilage repair and to further determine a suitable delivering hydrogel in a rat model. Critical sized full thickness cartilage defects were created. The hUCB-MSCs and three different hydrogel composites (hydrogel A; 4% hyaluronic acid/30% pluronic (1:1, v/...

Chemotherapy is one of the most conventionally used therapeutic interventions for treating various diseases. Chances of acquiring multidrug resistance in response to chemotherapeutic agents are exceedingly common among patients. Drug resistance arises mainly due to overexpression of efflux transporters such as P-glycoprotein and multidrug resistance-associated protein of the ATP-binding cassett...

Recent data suggest that dietary fat promotes intestinal absorption of lipopolysaccharides (LPS) from the gut microflora, which might contribute to various inflammatory disorders. The mechanism of fat-induced LPS absorption is unclear, however. Intestinal-epithelial cells can internalize LPS from the apical surface and transport LPS to the Golgi. The Golgi complex also contains newly formed chy...
