Abstract: The present disclosure is related to systems and methods for image registration. The method includes obtaining a first image of a first modality associated with a subject and a second image of a second modality associated with the subject. The method includes determining a first region of interest (ROI) in the first image and a second ROI in the second image, wherein the first ROI and the second ROI correspond to a same region of the subject. The method includes registering the first ROI and the second ROI.

Abstract: A processing cartridge is able to detachably mounted in an electronic imaging device, and includes a drum unit, including a photosensitive frame, on which a photosensitive drum is rotatably supported; and a developing unit, including a developing frame, on which a developing roller is rotatably supported. The developing unit is pivotally connected to the drum unit, and is able to move between a contact position and a separation position around a rotation axis relative to the drum unit. The processing cartridge further includes a control structure configured to limit the movement of the developing unit along a separation direction under the action of the self-gravity of the developing unit, so that the processing cartridge may not separate the drum and roller under the self-gravity of the developing unit.

Abstract: Disclosed are a deuterated 1,4-benzodiazepine-2,5-dione compound and the use thereof. Provided is a compound as represented by formula I or a pharmaceutically acceptable salt thereof. The disclosed 1,4-benzodiazepine-2,5-dione active compound maintains the activity of inhibiting tumor cells and tumor stem cells, and prolongs the degradation function of in-vitro human liver microsomes on the compound, such that the half-life period is significantly prolonged, which provides a safer and more reliable candidate for developing new anti-tumor drugs.
