Abstract: A multi-focus histotripsy method based on a pulsed ultrasound phased array with hundred elements is provided. Excitation amplitude and phase of individual elements are regulated to control a phased array to produce multiple focus modes. A two-stage histotripsy is performed based on these focus modes. In a first stage, a first pulsed ultrasound is applied to an experimental sample in a target area to induce generation of cavitation microbubbles and boiling bubbles to preliminarily homogenize the experimental sample to form a loose product; and in a second stage, the experimental sample is mechanically disrupted and homogenized using a second pulsed ultrasound. The first pulsed ultrasound and the second pulsed ultrasound each are a hundred micro-second pulse or a milli-second pulse. Duty cycles of the first pulsed ultrasound and the second pulsed ultrasound are 3-10% and less than 2%, respectively. A multi-focus histotripsy system is further provided.

Abstract: The present invention provides a novel anti-CD73 monoclonal antibody. The antibody has high affinity for human CD73 protein. Both biochemical-level and cell-level experiments show that the antibody is highly effective in inhibiting the enzyme activity of CD73. The in-vivo experiment indicates that the antibody has a significant inhibition effect on tumor cell growth. In particular, the antibody does not have the “hook effect” most prior art antibodies have in connection with inhibition of the enzyme activity of CD73, and is therefore more suitable for clinical use than the prior art antibodies.
