  • Publication number: 20250026881
    Abstract: Oligoesters and polyesters comprising one or more (e.g., a plurality) of crosslinkable and/or crosslinked clickable groups (e.g., capable of or formed by click reactions, respectively). methods of making same. and uses of same. In various examples, a method forms objects by irradiating compositions comprising crosslinkable oligoesters and polyesters and, optionally, solvent (e.g., crosslink-able solvent), crosslinking reagent, and/or crosslinking initiator, with electromagnetic radiation and/or by heating the compositions. In various examples, a method forms films, fibers, and other 3D objects. In various examples, biodegradable and/or elastomeric materials comprising crosslinked oligoesters and polyesters are useful in devices (e.g., microfluidic devices, lab on a chip, drug delivery devices, and the like), scaffolds, tissue grafts, skin patches, and the like. In various examples, methods are additive manufacturing methods, (e.g., 3D printing methods, such as, for example, digital light processing (DLP)).

  • Patent number: 10081810
    Abstract: The present invention provides a c-Rel-specific siRNA and its use for preventing and treating autoimmune psoriasis. In particular, the c-Rel-specific siRNAs have sequences as shown in SEQ ID Nos. 1-2 or SEQ ID Nos. 3-4. In the present invention, small interfering RNA (siRel) specific to c-Rel are employed to inhibit c-Rel biosynthesis, and prevent and treat autoimmune psoriasis by inhibiting inflammatory factors relating to IL-23/IL-17A inflammatory axis.
