Abstract: Provided herein are methods of treating cancer in a subject including detecting an amount of PD-L1(+) natural killer (NK) cells in a biological sample from the subject and treating the subject with an anti cancer therapy. Provided herein are methods of treating cancer in a patient including isolating natural killer (NK) cells from a subject, producing a population of PD-L1(+) NK cell from the isolated NK cells, and administering the population of PD-L1(+) NK cells into the patient.

Abstract: In a described embodiment, a UAV and method for controlling a UAV are disclosed. The UAV is controlled along a predetermined flight path and the camera of UAV is controlled such that adjacent pictures of the captured pictures have an overlap in a predetermined range. In another embodiment, a device and method for detecting defects in image data of a UAV camera are disclosed. An image data management system for managing image data of a UAV and a client software application for performing surface scans with a UAV are also disclosed.

Abstract: Provided are a recombinant adeno-associated virus (AAV) vector carrying human papillomavirus type 16 (HPV-16) mutation E7 antigen gene and a construction method therefor. The construction method comprises mutating the carcinogenic HPV-16 E7 antigen gene to noncarcinogenic E7 antigen gene, and then inserting the mutated gene into an AAV vector of which the structural gene has been removed, thereby obtaining the recombinant AAV vector. The recombinant AAV vector or related product can be used for preparing medications against HPV-16 infection and other diseases such as tumors caused by HPV-16 infection.
