1. Structural studies of microbubbles and molecular chaperones using transmission electron microscopy
Abstract : Ultrasound contrast agents (CAs) are typically used in clinic for perfusion studies (blood flow through a specific region) and border delineating (differentiate borders between tissue structures) during cardiac imaging. The CAs used during ultrasound imaging usually consist of gas filled microbubbles (MBs) (diameter 1-5 μm) that are injected intravenously into the circulatory system. READ MORE

2. Exploring Polymer-Shelled Microbubbles: Detection Modeling and Application
Abstract : Ultrasound imaging (US) is widely used in clinical practice. Given the low cost and easy access to the ultrasound machine, US has a great potential to improve the health care condition for the majority of the population in the world. The US could be significantly improved by injecting ultrasound contrast agents to opacify the bloodstream. READ MORE

3. Ultrasound-enhanced Fibrinolysis Pro-fibrinolytic and Non-beneficial Effects Of Ultrasound Exposure
Abstract : The aim of this study was to further clarify the pro-fibrinolytic effects, and to explore the possible non-beneficial effects in ischemic organs, during exposure to pulsed ultrasound. This was accomplished by studies of the effects of different intensities of pulsed ultrasound exposure on the fibrinolytic properties of streptokinase and reteplase. READ MORE

4. Nano-Engineered Contrast Agents : Toward Multimodal Imaging and Acoustophoresis
Abstract : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.
