The Use of Ultrasound and Micelles in Cancer Treatment
(American Scientific Publishers, 2008)
The high toxicity of potent chemotherapeutic drugs like Doxorubicin (Dox) limits the therapeutic window in which they can be applied. This window can be expanded by controlling the drug delivery in both space and time such ...
Non-Viral Gene Transfection with Ultrasound: Is 100% Transfection Possible?
(American Scientific Publishers, 2012)
Ultrasound has been used as a modality to enhance the transfection of cells, purportedly via entry of genetic material through defects in the cell membrane produced by bubble cavitation events. A mathematical model was ...
Release of Doxorubicin from Unstabilized and Stabilized Micelles Under the Action of Ultrasound
(American Scientific Publishers, 2007)
Polymeric micelles are being investigated as chemotherapy drug delivery carriers using ultrasound as a trigger mechanism. The aim of this paper is to measure the release of Doxorubicin (Dox) from the core of unstabilized ...
Preliminary Results of Combining Low Frequency Low Intensity Ultrasound and Liposomal Drug Delivery to Treat Tumors in Rats
(American Scientific Publishers, 2011)
Ultrasound is a convenient trigger for site-specific drug delivery in cancer therapy. Nanosized liposomes formulated from soy phosphatidyl choline, cholesterol, 1,2-distearoyl-sn-glycero- 3-phosphoethanolamine-N-[carboxy ...
DNA damage induced by micellar-delivered doxorubicin and ultrasound: comet assay study
(Elsevier, 2000)
To minimize adverse side effects of chemotherapy, we have developed a micellar drug carrier that retains hydrophobic drugs, and then releases the drug by ultrasonic stimulation. This study investigated the DNA damage induced ...
Factors affecting acoustically triggered release of drugs from polymeric micelles
(Elsevier, 2000)
A custom ultrasonic exposure chamber with real-time fluorescence detection was used to measure acoustically-triggered drug release from Pluronic P-105 micelles under continuous wave (CW) or pulsed ultrasound in the frequency ...
Intracellular uptake of Pluronic copolymer: effects of the aggregation state
(Elsevier, 2002)
The effect of the Pluronic P-105 aggregation state on its uptake by HL-60 cells was studied by flow cytometry, fluorescence spectroscopy, and confocal and fluorescence microscopy using a fluorescently labeled Pluronic P105. ...
Ultrasonic release of doxorubicin from Pluronic P105 micelles stabilized with an interpenetrating network of N,N diethylacrylamide
(Elsevier, 2002)
Pluronic P105 micelles sequester hydrophobic drugs and release them upon insonation with low frequency ultrasound; however these micelles dissolve relatively quickly upon dilution. The objective of this research was to ...
Investigating the mechanism of acoustically activated uptake of drugs from Pluronic micelles
(BioMed Central (BMC), 2002)
Background: This paper examines the mechanism of ultrasonic enhanced drug delivery from Pluronic micelles. In previous publications by our group, fluorescently labeled Pluronic was shown to penetrate HL-60 cells with and ...
Ultrasonic-Activated Micellar Drug Delivery for Cancer Treatment
(Wiley InterSciences, 2008)
The use of nanoparticles and ultrasound in medicine continues to evolve. Great strides have been made in the areas of producing micelles, nanoemulsions, and solid nanoparticles that can be used in drug delivery. An effective ...
