  • Publication number: 20230277598
    Abstract: Disclosed are means, treatments and compositions of matter useful for treatment of chemotherapy/radiotherapy associated cognitive dysfunction. In one embodiment the invention provides the administration of mesenchymal stem cell apoptotic bodies alone or in combination with “regenerative adjuvants” to prevent and/or reverse cognitive dysfunction associated with chemotherapy and/or radiation therapy. In other embodiments the invention teaches the utilization of stem cell apoptotic bodies for induction of neuroregeneration directly or indirectly.

  • Patent number: 8697032
    Abstract: The present invention relates to compositions and methods for preparing radiopharmaceutical compounds in high chemical-purity and isotopic-purity. The present invention provides polymer-bound precursors to radiopharmaceutical compounds that can be converted to radiopharmaceutical compounds in one step. In a preferred embodiment, a radiopharmaceutical precursor is bound to a polymeric support via a prosthetic group comprising an alkenyl-tin bond. The radiopharmaceutical precursor is converted to a radiopharmaceutical compound in one step involving cleavage of the alkenyl-tin bond and incorporation of a radioisotope to form the radiopharmaceutical compound. Importantly, the polymeric support containing the toxic tin by-product can be easily removed from the radiopharmaceutical compound by filtration. The present invention can be used to install a large number of different radioisotopes. In a preferred embodiment, the radioisotope is 211At, 123I, or 131I.
