    摘要: In a method for characterizing the angiogenesis status of a tumor in a living subject, timed magnetic resonance images of the subject into whom a reptating polymer contrast agent containing chelating diethylentriaminepentacetic acid dosed with gadolinum has been introduced are obtained. At least two images taken at different times are compared in order to determine the percentage image enhancement in a tumor region of interest. A contrast agent including a reptating polymer containing technetium-99 is used with a nuclear medicine version of this technique.

    摘要: A generic structure for the peptides of the present invention includes A-X-B-C, where C is a cargo moiety, the B portion includes basic amino acids, X is a cleavable linker sequence, and the A portion includes acidic amino acids. The intact structure is not significantly taken up by cells; however, upon extracellular cleavage of X, the B-C portion is taken up, delivering the cargo to targeted cells. Cargo may be, for example, a contrast agent for diagnostic imaging, a chemotherapeutic drug, or a radiation-sensitizer for therapy. X may be cleaved extracellularly or intracellularly. The molecules of the present invention may be linear, cyclic, branched, or have a mixed structure.
