Collapse dynamics of ultrasound contrast agent microbubbles
Ultrasound contrast agents (UCAs) are micron-sized gas bubbles encapsulated with thin shells on the order of nanometers thick. The damping effects of these viscoelastic coatings are widely known to significantly alter the bubble dynamics for linear and low-amplitude behavior; however, their effects …

Attachment mechanisms of a novel, targeted, lipid-based, ultrasound contrast agent
… of a novel, targeted, lipid-based, microbubble ultrasound contrast agent (UCA) for assessment of coronary heart disease (CHD) with high frequency intravascular ultrasound (IVUS). The targeting mechanisms assessed for microbubble attachment include a streptavidin-biotin mechanism, electrostatic …

Examining the biophysics of ultrasound and contrast agent induced angiogenesis
… treatments. Current research suggests that ultrasound-ultrasound contrast agent treatment can be therapeutically beneficial, providing a noninvasive way to spatially and temporally target ischemic tissues. This type of angiogenic therapy can be used as an alternative to high risk …

Fibrin targeting microbubbles for the detection of nascent surgical adhesions
… the use of fibrin-targeting microbubbles as an ultrasound contrast agent to diagnose peritoneal adhesions. Fibrin targeting is achieved by integrating a CREKA (Cys-Arg-Glu-Lys-Ala) peptide into the microbubble shell. The properties of targeted and non-targeted microbubbles made from three lipid …

Ultrasound mediated Targeted Drug Delivery In Vitro: design, evaluation and application
… various methods of drug release, one of which is ultrasound, as in ultrasound-mediated TDD (USmTDD). The combination of focused ultrasound (FUS) and magnetic resonance imaging (MRI) provides a controllable system of drug release and impact assessment. <br/>In the work reported here, a novel drug …

Diagnostische Wertigkeit der nativen und der kontrastmittelverstärkten Dobutamin-Stressechokardiographie und der Gewebedoppleruntersuchung bei Patienten mit angiographisch mittelgradigen Koronarstenosen
Herz-Kreislauferkrankungen sind weltweit die häufigste Ursache für Tod oder Hospitalisation. Um die Mortalitätsrate an KHK, Myokardinfarkt und Herzinsuffizienz günstig zu beeinflussen, ist es wichtig, eine chronisch ischämische Herzkrankheit möglichst frühzeitig zu diagnostizieren, ihren …

Echogenic Liposomes For Nitric Oxide Delivery and Breast Cancer Treatment
… proposed as a carrier for drugs and antitumor agents in cancer chemotherapy. Echogenic liposomes (ELIP) have the potential to entrap air or bioactive gas to enhance acoustic reflectivity in ultrasound and are used as a contrast agent. The innovative part of this study is based on a novel …
