Abstract: Provided are porogen compositions and methods of using such porogen compositions in the manufacture of porous materials, for example, porous silicone elastomers. The porogens generally include comprising a core material and shell material different from the core material. The porogens can be used to form a scaffold for making a resulting porous elastomer when the scaffold is removed.

Abstract: Dermal fillers are provided, particularly hyaluronic acid-based dermal fillers containing additives, for example, unstable additives, the dermal fillers being provided in an anhydrous state for extended shelf life.

Abstract: Hydrogels comprising a macromolecular matrix and water may be used to augment soft tissue of a human being, promote or support cell or tissue viability or proliferation, create space in tissue, and for other purposes. A macromolecular matrix may comprise a hyaluronic acid component crosslinked to a collagen component.

Abstract: Provided are injectable, hyaluronic acid-based hydrogel compositions including conjugated vitamins.

Abstract: A method and a device for transmitting signals among compartments of a train are provided. The method comprises: S1, receiving a first signal transmitted via a jumper cable, and extracting first data carried in the first signal; S2, receiving a second signal transmitted wirelessly corresponding to the first signal, and extracting second data carried in the second signal; and S3, determining whether the first data is identical with the second data, and outputting the first signal in a case that it is determined that the first data is identical with the second data, or outputting the second signal in a case that it is determined that the first data is not identical with the second data. The method and the device improve the reliability of transmission of signals among compartments of a train.

Abstract: Compositions useful as dermal fillers and methods using such compositions to treat various skin and soft tissue conditions. The dermal fillers can comprise silk attached to hyaluronic acid using for example two cross linkers and can be used to treat of facial imperfections, facial defects, facial augmentations, breast imperfections, breast augmentations or breast reconstructions.

Abstract: The present invention provides highly injectable, long-lasting hyaluronic acid-based hydrogel dermal filler compositions which are particularly advantageous for correction of fine lines in the face.

Abstract: Provided are injectable, hyaluronic acid-based dermal filler compositions including conjugated vitamin C derivatives. The compositions provide for extended release of active vitamin C into tissue, promoting collagenesis and other benefits to skin.
