  • Patent number: 11961974
    Abstract: A battery cell capable of self-priming with molten metal produced within the battery cell includes a cathode compartment configured to contain a catholyte that releases metal ions, an anode compartment at least partially containing an anode current collector that receives electrons from an external power supply, an ion-selective membrane positioned between the cathode compartment and the anode compartment and configured to selectively transport the metal ions from the cathode compartment to the anode compartment when self-priming the battery cell, and an electron transport structure extending between the anode current collector and the ion-selective membrane within the anode compartment and configured to transport the electrons from the anode current collector to the ion-selective membrane when self-priming the battery cell.

  • Publication number: 20110300098
    Abstract: Methods for treating cancer by co-administering a therapeutic monoclonal antibody with IL-21 are described. Exemplary monoclonal antibodies that can be used are rituximab, trastuzumab and anti-CTLA-4 antibodies. The enhanced antitumor of the combination therapy is particularly useful for patient populations that are recalcitrant to monoclonal therapy, relapse after treatment with monoclonal antibodies or where the enhanced IL-21 antitumor effect reduces toxicities associated with treatment using the monoclonal antibodies.
