  • Publication number: 20240108655
    Abstract: The present invention provides methods used to condition recipients of organ transplants to achieve tolerance using a novel non-myeloablative conditioning regime featuring total lymphoid irradiation (TLI) and total body irradiation (TBI), each provided as a fractionated series of doses. Advantageously, this regime not only provides better conditioning than existing non-myeloablative regimes, but also does not require extending the typical duration of the conditioning course.

  • Patent number: 11923391
    Abstract: A moiré pattern imaging device includes a light-transmissive film and a light-shielding film. The light-transmissive film includes a plurality of imaging units and a light-incident surface and a light-emergent surface opposite to each other. The plurality of imaging units are disposed on the light-incident surface, the light-emergent surface, or a combination thereof and are arranged in two dimensions to form an imaging unit array. The light-shielding film includes a plurality of light-transmissive regions. The light-transmissive regions are arranged in two dimensions to form a light-transmissive array, and the light-shielding film is overlaid on the light-incident surface or the light-emergent surface. The light-transmissive array corresponds to the imaging unit array. The imaging unit array and the light-transmissive array together form a moiré pattern effect to generate an image magnification effect.

    Abstract: Interferon-alpha (IFN?) analog proteins modified by chemical attachment of at least one hydrophilic polymer moiety, such as polyethylene glycol chain, are described for use in combination therapies with antiviral and/or antitumor agents. In one embodiment, the IFN? analog protein has an amino acid sequence that differs from a native human IFN? interferon-alpha by one or more amino acid residues in the N-terminal region, comprised of between about residues 1-27, inclusive, by one or more substitutions selected based on the amino acid residue at the corresponding position of a mature interferon-tau (IFN?) protein. Methods of combination therapy are also described.
