This work evaluated the potential of Pluronics (varieties F127 and P123) in combination with solubilizing agents to be used as syringeable in situ gelling depots of intratumoral β-lapachone (βLAP). Pluronic dispersions prepared at various concentrations in the absence and the presence of ethanol and randomly methylated β-cyclodextrin (RMβCD) were characterized regarding their rheological proper...
There is an unmet need to develop strategies that allow site-specific delivery of short interfering RNA (siRNA) without any associated toxicity. Here we report a modular system can be custom modified with targeting peptide and siRNAs.
<img src=” https://s3.amazonaws.com/production.scholastica/article/37505/large/prnano_812022ga_2.jpg?1661898072”> Ionically complexed nanoparticles were prepared from an anionic polysaccharide drug, heparin, entrapped by a positively charged chitosan polysaccharide. In this study, the encapsulation of heparin was studied to optimize properties needed for its oral drug delivery. Chitosan, ...
In order to get a better understanding of amoeba-substrate interactions in the processes of cellular adhesion and directional movement, we engineered glass surfaces with defined local adhesion characteristics at a micrometric scale. Amoeba (Dictyostelium dicoideum) are capable to adhere to various surfaces independently on the presence of extracellular matrix proteins. This paper describes the ...
The purpose of this research was to develop a topical microsphere delivery system in a thermosensitive 20% poloxamer 407 gel (Pluronic F127) to control release of KSL-W, a cationic antimicrobial decapeptide, for a period of 4-7 days for potential application in combat related injuries. KSL-W loaded microsphere formulations were prepared by a solvent extraction-evaporation method (water-oil-wate...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
Temperature-sensitive hyaluronic acid (HA) hydrogels were synthesized by photopolymerization of vinyl group modified HA in combination with acrylate group end-capped poly(ethylene glycol)-poly(propylene glycol)-poly(ethylene glycol) tri-block copolymer (Pluronic F127). The synthesized HA/Pluronic composite hydrogels gradually collapsed with increasing temperature over the range of 5-40 degrees ...
Pluronic based formulations are among the most successful nanomedicines and block-copolymer micelles including drugs that are undergoing phase I/II studies as anticancer agents. Using coarse-grained models, molecular dynamics simulations of large-scale systems, modeling Pluronic micelles interacting with DPPC lipid bilayers, on the μs timescale have been performed. Simulations show, in agreemen...
