A preparation method of a hemostatic material is provided, wherein the method mainly includes mixing a keratin and an alginate; obtaining a keratin-alginate composite scaffold by a freeze-gelation method; and drying the keratin-alginate composite scaffold to obtain a hemostatic material. Further, a methylene blue can be loaded into the hemostatic material so that the hemostatic material has antimicrobial photodynamic abilities.

Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

Disclosed are adjustable intraocular lenses and methods of adjusting intraocular lenses post-operatively. In one embodiment, an adjustable intraocular lens can comprise an optic portion and a peripheral portion. The peripheral portion can comprise a composite material comprising an energy absorbing constituent and a plurality of expandable components. A base power of the optic portion can be configured to change in response to an external energy directed at the composite material.

Disclosed are adjustable accommodating intraocular lenses and methods of adjusting accommodating intraocular lenses post-operatively. In one embodiment, an adjustable accommodating intraocular lens comprises an optic portion and a peripheral portion. At least one of the optic portion and the peripheral portion can be made in part of a composite material comprising an energy absorbing constituent and a plurality of expandable components. At least one of a base power and a cylindricity of the optic portion can be configured to change in response to an external energy directed at the composite material.

Methods for treating tissue are provided. In one embodiment, an adjunct material, when secured to tissue, can receive at least one physiological element released from the tissue during healing progression of the tissue, and can exhibit first and second stiffnesses in compression that are approximately constant during first and second time periods from contact with the tissue, with the second stiffness decreasing with time as a function of at least one of oxidation, enzyme-catalyzed hydrolysis, and change of pH resulting from interaction with the at least one physiological element. In another embodiment, the adjunct can receive a unit volume of fluid that causes first and second portions of the adjunct to expand according to first and second expansion behaviors that differ from one another to apply different pressures to the tissue.

Ink formulations comprising bioactive particles, methods of printing the inks into three-dimensional (3D) structures, and methods of making the inks are provided. Also provided are objects, such as tissue growth scaffolds and artificial bone, made from the inks, methods of forming the objects using 3D printing techniques, and method for growing tissue on the tissue growth scaffolds. The inks comprise a plurality of bioactive ceramic particles, a biocompatible polymer binder, optionally at least one bioactive factor, and a solvent.

An injectable medical composition includes an acrylate and a solvent. The composition has a first viscosity at temperatures below body temperature and a second viscosity at body temperature. The first viscosity is lower than the second viscosity.

Blockchain environments may mix-and-match different encryption, difficulty, and/or proof-of-work schemes when mining blockchain transactions. Each encryption, difficulty, and/or proof-of-work scheme may be separate, stand-alone programs, files, or third-party services. Blockchain miners may be agnostic to a particular coin's or network's encryption, difficulty, and/or proof-of-work schemes, thus allowing any blockchain miner to process or mine data in multiple blockchains. GPUs, ASICs, and other specialized processing hardware components may be deterred by forcing cache misses, cache latencies, and processor stalls. Hashing, difficulty, and/or proof-of-work schemes require less programming code, consume less storage space/usage in bytes, and execute faster. Blockchain mining schemes may further randomize byte or memory block access, further improve cryptographic security.
