Boosting high-intensity focused ultrasound-induced anti-tumor immunity using a sparse-scan strategy that can more effectively promote dendritic cell maturation

Zhong, Pei (BIOMED CENTRAL LTD, 2010)

Background: The conventional treatment protocol in high-intensity focused ultrasound (HIFU) therapy utilizes a dense-scan strategy to produce closely packed thermal lesions aiming at eradicating as much tumor mass as ...
Displacement of particles in microfluidics by laser-generated tandem bubbles

Lautz, Jaclyn; Sankin, Georgii; Yuan, Fang; Zhong, Pei (AMER INST PHYSICS, 2010)

The dynamic interaction between laser-generated tandem bubble and individual polystyrene particles of 2 and 10 mu m in diameter is studied in a microfluidic channel (25 mu m height) by high-speed imaging and particle image ...
Effect of lithotripter focal width on stone comminution in shock wave lithotripsy

Qin, Jun; Simmons, Walter; Sankin, Georgii; Zhong, Pei (ACOUSTICAL SOC AMER AMER INST PHYSICS, 2010)

Using a reflector insert, the original HM-3 lithotripter field at 20 kV was altered significantly with the peak positive pressure (p(+)) in the focal plane increased from 49 to 87 MPa while the -6 dB focal width decreased ...
Optimization of Treatment Strategy Used During Shockwave Lithotripsy to Maximize Stone Fragmentation Efficiency

Yong, Daniel Z.; Simmons, Walter Neal; Lipkin, Michael Eric; Sankin, Georgii; Albala, David Mois; Zhong, Pei; Preminger, Glenn Michael (Journal of Endourology, 2011-09)

Background and Purpose: Previous studies have demonstrated that treatment strategy plays a critical role in ensuring maximum stone fragmentation during shockwave lithotripsy (SWL). We aimed to develop an optimal treatment ...
Pulsating Tandem Microbubble for Localized and Directional Single-Cell Membrane Poration

Sankin, Georgii; Yuan, Fan; Zhong, Pei (AMER PHYSICAL SOC, 2010)

The interaction of laser-generated tandem microbubble (maximum diameter of about 50 mu m) with single (rat mammary carcinoma) cells is investigated in a 25-mu m liquid layer. Antiphase and coupled oscillation of the tandem ...
