Selective Ablation of Cancer Cells with Low Intensity Pulsed Ultrasound [PDF]
, 2020 Ultrasound can be focused into deep tissues with millimeter precision to perform noninvasive ablative therapy for diseases such as cancer. In most cases, this ablation uses high intensity ultrasound to deposit nonselective thermal or mechanical energy at

Distinct immune signatures in directly treated and distant tumors result from TLR adjuvants and focal ablation. [PDF]
, 2018 Both adjuvants and focal ablation can alter the local innate immune system and trigger a highly effective systemic response. Our goal is to determine the impact of these treatments on directly treated and distant disease and the mechanisms for the ...
