Abstract: A loading apparatus for rock fracturing simulation includes an upper cover plate, a lower cover plate, lateral pressure pieces, and an acoustic measurement module top pillar. There are at least two lateral pressure pieces which are provided with a force applying face respectively for transmitting a radial force to a core sample. The upper cover plate, the lower cover plate and the lateral pressure pieces enclose a loading space for placing the core sample, and the lateral pressure pieces can slide along a radial direction of the core sample and relative to the upper cover plate or the lower cover plate. The lateral pressure pieces are provided with a sensor inserting hole for allowing a sensor to pass through respectively, and the sensor is attached to an outer peripheral wall of the core sample.

Abstract: Provided are exosomes derived from V?2-T cell (V?2-T-Exos) for killing or inhibiting EBV-infected cells. Further provided is a method for killing or inhibiting the growth of an EBV-infected cell, comprising contacting the EBV-infected cell with exosomes from V?2+ T cells in an amount effective to kill or inhibit the growth of the cell. Preferably, the EBV-infected cell is an EBV-infected cell that has become neoplastic, such as an EBV-infected neoplastic B-cell or an EBV-infected neoplastic epithelial cell. Further provided is a method for treating an EBV-induced cancer in a subject by administering to the subject a therapeutically effective amount of V?2-T-Exos. V?2-T-Exos can be derived from V?2-T cells obtained from the subject or from an allogeneic healthy individual. Methods for isolating V?2-T-Exos from V?2-T cells are also provided.
