Abstract: User interface methods and systems are provided for interfacing with a plurality of objects in three-dimensional virtual environment providing for a medical imaging workspace. A method includes identifying one of a plurality of objects arranged in a three-dimensional virtual medical imaging workspace as a user-intended contextual selection based on detected gaze tracking information and establishing a command context based on the identified object. The command context comprises voice-activated commands, gesture-activated commands, or a combination thereof. The method further includes activating an object-specific action based on a detected voice or gesture command.

Abstract: Disclosed are methods for the genetic construction and expression of antibody-based fusion proteins with enhanced circulating half-lives. The fusion proteins of the present invention lack the ability to bind to immunoglobulin Fc receptors, either as a consequence of the antibody isotype used for fusion protein construction, or through directed mutagenesis of antibody isotypes that normally bind Fc receptors. The fusion proteins of the present invention may also contain a functional domain capable of binding an immunoglobulin protection receptor.

Abstract: Disclosed herein are methods and compositions for enhancing the immunogenicity of a preselected protein or peptide antigen in a mammal. Immunogenicity is enhanced by fusing the preselected antigen to an immunoglobulin heavy chain constant region to produce an Fc-antigen fusion protein. The Fc-antigen fusion proteins bind Fc receptors on the surface of antigen presenting cells, thereby targeting the antigen to the antigen presenting cells in the mammal. In addition, disclosed is a family of adjuvants, for example, an Fc-adjuvant fusion protein, for use in combination with the Fc-antigen fusion proteins to enhance or modulate a particular immune response against the preselected antigen.

Abstract: Disclosed are chemical agents for modulating certain cellular immune reactions that can lead to autoimmune disorders. By specific modulation, harmful immune reactions can be lessened in severity or even prevented without resorting to potentially dangerous general immune suppression. The described chemical agents inhibit IL-12 induction of the secretion of key immune modulators. The described chemical agents are specific inhibitors of IL-12 induced Th1 immune response.
