Nanoparticulate, ion-paired complexes of melittin (MLN) and one or more non-steroidal anti-inflammatory drugs, and particularly MLN ion-paired with diclofenac, provide for enhanced wound healing in humans and other animals. Compositions having the nanonparticulates distributed therein or thereon are applied topically to the wound, and the ion-paired complexes have been shown to demonstrate superior wound healing and closure.

Tissue prostheses having a base structure and a physiological sensor system. The tissue prostheses are adapted and configured to induce remodeling of damaged tissue and regeneration of new tissue and concurrently detect and monitor physiological characteristics when implanted in the subject.

Provided is a method for suppressing the generation of diclofenac lactam from a compound represented by a formula (1) in the description, including allowing the compound of the formula (1) and a component (A) that is at least one type of compound selected from the group consisting of a nonionic surfactant, a hydroxyalkylated cyclodextrin, a C1 to C3 mono-alcohol, a C2 to C3 di-alcohol, a C3 to C6 tri-alcohol, a polyalkylene glycol, a γ-lactone, polyvinylpyrrolidone, a chlorogenic acid, and an alkyl sulfate ester, and salts thereof to coexist. A method for producing a pharmaceutical composition containing a compound represented by the formula (1) and a component (A), and a pharmaceutical composition which is a product produced thereby are also provided.

Methods and devices for tissue remodeling and repair of collagenous tissues, including tendons, ligaments, and bone, as well as scalable connective tissue manufacturing, are provided. Collagen fibers are assembled by extensional strain-induced flow crystallization of collagen monomers. Extensional strain also drives the fusion of already formed short collagen fibrils to produce long-range, continuous fibers. Wearable devices for controlled tissue remodeling and wound healing deliver a tissue remodeling solution to a tissue repair site. The remodeling solution, together with appropriate application of strain to the tissue remodeling site, accelerate healing, prevent injury, and reduce scar formation.

The present disclosure relates to injectable compositions capable of forming a scaffold in situ at an intervertebral disc site, the composition comprising: (a) a biocompatible polymer; and (b) a biocompatible solvent system in sufficient amount to solubilize the biocompatible polymer in sufficient degree to allow injectable delivery to a disc site.

Provided is an implant material, an implant suitable for implantation in bone defect repair and in spinal fusion, and a preparation method thereof. The implant material is used for filling in an internal cavity of a titanium cage/titanium stent (10) or a bone defect site, and is consisted of an upper layer (21), a lower layer (22) and an intermediate layer between the upper layer (21) and lower layer (22), wherein the intermediate layer is composed of an annular coating region (23) located at the periphery and a central region (24) located inside the annular coating region. The central region (24) is filled with a first filling material, which is a gel material having a pro-osteogenic effect. The annular coating region (23) is filled with a second filling material, which is a gel material regulating epigenetics. The upper layer (21) and lower layer (22) are filled with a third filling material, which is a gel material regulating immuno-inflammatory response and stress response. The implant of the present disclosure can adapt to the microenvironment of different regions of the injury sites and orderly regulate the repair process, and is suitable for implantation in bone defect repair and spinal fusion.

Disclosed is a drug delivery system that specifically carries and releases an active substance to a target organ or tissue. The coating of the shape memory component constituting the drug delivery system enhances the biocompatibility and controlled delivery of the active substance previously loaded into the coating material to the target organ or tissue

Methods and compositions for reducing a ratio of collagen III to collagen I in wounded skin, treating wounds and accelerating healing is provided with a surfactant polymer dressing comprising FL2 siRNA, collagen and a poloxamer.

A medical device including a substrate and a hydrophilic polymer layer and satisfying the following conditions: (1) that the hydrophilic polymer layer is on at least a part of the substrate; (2) that the hydrophilic polymer layer contains: a hydrophilic polymer having an acidic group; and a compound having an acidic group and a ring structure; and (3) that a time during which a liquid film is retained on the surface of the medical device (a liquid film retention time) is 10 seconds or more after the medical device is stationarily immersed in a phosphate buffer solution, pulled up from the phosphate buffer solution, and retained in the air. The present invention provides a medical device in which a surface of a substrate is hydrophilized, and a method for manufacturing same by a simple method.

The present invention provides new classes of phenol compounds, including those derived from tyrosol and analogues, useful as monomers for preparation of biocompatible polymers, and biocompatible polymers prepared from these monomeric phenol compounds, including novel biodegradable and/or bioresorbable polymers. These biocompatible polymers or polymer compositions with enhanced bioresorbabilty and processability are useful in a variety of medical applications, such as in medical devices and controlled-release therapeutic formulations. The invention also provides methods for preparing these monomeric phenol compounds and biocompatible polymers.
