Abstract: Systems and methods for detecting metal clips inserted within a portion of a body of a patient are disclosed herein. In one embodiment, a clip detector assembly includes a detector having a ferrous member, a transmitting coil around the ferrous member and configured to induce a current in the metal clip, and a receiving coil around the ferrous member and configured to receive a magnetic field generated by the current induced in the metal clip. The assembly can further include a control circuit having a band-pass filter configured to pass electrical signals induced by the magnetic field from the receiving coil that are within at most 35 kHz of a resonance frequency of the metal clip. The assembly still further includes a user notification component configured to alert a user to a location of the metal clip.

Abstract: Provided herein is a pharmaceutical combination comprising SFRP2 antagonist and an PD-1 antibody antagonist. The invention also provides a method for the treatment of cancer, comprising the administration of a therapeutically effective amounts of a SFRP2 antagonist and a PD-1 antagonist to a patient in need thereof.

Abstract: Provided are compositions and methods for imaging one or more of tumor vasculature and tumor angiogenesis, wherein an imaging composition comprises anti-SFRP2 antibody operable linked to an imaging agent. Provided is a method of imaging tumor vasculature in an individual comprising administering to the individual a diagnostically effect of an imaging composition, and detecting the image resulting from the binding or complexing of the imaging composition with tumor vasculature. The imaging agent may also be used as a delivery vehicle to target one or more therapeutic agents to tumor vasculature and surrounding tumor tissue.
