Related Articles Molecular imaging and Ultrasound-assisted drug delivery. J Endourol. 2008 Apr;22(4):795-802 Authors: Schneider M Ultrasound imaging is undergoing a major revolution, about to bring this modality well beyond its established role as a low-cost noninvasive real-time imaging modality. Particularly important has been the commercial availability of microbubble-based contrast agents. Several new indications for contrast Ultrasound have been developed and have entered clinical practice. The characterization of focal liver lesions and the follow-up of antiangiogenic therapy are two applications that will have a major impact in medical practice. Others, such as prostate cancer diagnosis, are still under investigation and need to be clinically validated. Thanks to its outstanding sensitivity, contrast-enhanced Ultrasound is also geared to become the preferred modality for molecular imaging of diseases occurring at the vascular level. Angiogenesis, inflammation, and other endothelial dysfunctions are important targets that can be imaged and investigated with targeted microbubbles. In the field of prostate cancer, targeted agents will facilitate detection and provide additional information on tumor size, and hopefully on aggressiveness as well. Ultrasound can also play a role to deliver drugs or genes locally. This is an exciting area that has become an important field of research. Imaging and drug delivery can be performed simulta ...

Related Articles Ultrasound-mediated microbubble destruction facilitates gene transfection in rat C6 glioma cells. Mol Biol Rep. 2008 Jul 12; Authors: Wang JF, Wu CJ, Zhang CM, Qiu QY, Zheng M The goal of this study was to determine whether Ultrasound (US) exposure combined with microbubble destruction could be used to enhance non-viral gene delivery in rat C6 glioma cells. Microbubbles were prepared and gently mixed with plasmid DNA. The mixture of the DNA and microbubbles was administered to cultured C6 cells under different US/microbubble conditions. Transfection efficiency and cell viability were assessed by FACS analysis, confocal laser scanning microscopy, and Trypan blue staining. The results demonstrate that microbubble with US exposure could significantly enhance the reporter gene expression as compared with other groups. No statistical significant difference was observed in the glioma cell viability between different groups. Our in vitro findings suggest that US-mediated microbubble destruction has the potential to promote safe and efficient gene transfer into C6 cells. This non-invasive gene transfer method may be useful for safe clinical gene therapy of brain cancer without a viral vector system. PMID: 18618290 [PubMed - as supplied by publisher] ...

Related Articles Adhesion and Ultrasound-induced delivery from monodisperse microbubbles in a parallel plate flow cell. J Control Release. 2008 Jun 29; Authors: Schmidt BJ, Sousa I, van Beek AA, Böhmer MR Microbubbles, Ultrasound contrast agents currently in development as ultrasonically activated drug delivery vehicles, were studied using a novel flow cell design. The flow cell combined Ultrasound compatibility, a planar optical configuration, and a Cartesian orientation of buoyant, shear, and acoustic forces. The set-up enabled measurements of buoyant rise and adhesive sensitivity to shear forces for individual biotinylated, monodisperse, polymer-shelled microbubbles near a NeutrAvidin-coated polystyrene substrate. Analysis of the velocity history demonstrated that adhesion depended on the buoyant rise to the surface before attachment to the substrate: only when the distance parallel to the substrate in the flow direction was between 10 and 20 mum from the stopping position could specific molecular recognition events occur. Low intensity Ultrasound caused strong two-dimensional mobility leading to reversible clustering of microbubbles, even though they interacted strongly with the substrate through biotin- NeutrAvidin bonds. At higher acoustic pressure, local gas release took place. With sufficient acoustic intensity, the agents demonstrate potential as large payload carriers for biomolecularly targeted therapeutic delivery. However ...

Abstract Purpose To engineer lactose crystals of desired size, shape, surface and particle size distribution (PSD) as a carrier for dry powder inhalers (DPI) by Ultrasound assisted in-situ seeding. Methods Lactose crystals were obtained from solution by Ultrasound assisted in-situ seeding, followed by growth in viscous glycerin solution. The crystals were characterized for physical properties and 63–90 μm size fractions of different batches were mixed with salbutamol sulphate (SS) and compared for in-vitro deposition. Results Cooling crystallization with stirring for 10–20 h resulted in crystals with wide PSD and varied shape. Application of Ultrasound resulted in rapid and complete crystallization in 5 min with rod-shaped fine crystals (15–30 μm) and narrow PSD. In-situ seeded batches yielded micro-fine rod-shaped seed crystals. Seeding followed by growth in glycerin showed desirable size, high elongation ratio, smooth surface and narrow PSD, while growth under stirring showed high elongation ratio with rough surface. Crystals grown in glycerin showed highest dispersibility and fine particle fraction (FPF) of SS. Conclusions Ultrasound assisted in-situ seeding, followed by ordered growth in glycerin offers rapid technique for separation of nuclei induction from crystal growth yielding desirable characteristics for better dispersion and in-vitro deposition when employed as DPI carrier.
