METHOD FOR BONE HEALING OR TREATMENT OF BONE FRACTURE
A method for bone healing or treatment of bone fracture in a subject includes optionally pre-drilling a hole or creating a cavity in a body tissue, implanting a device onto or into the body tissue, or at least partially inserting a device into the cavity or hole, administering a composition into the device and/or near the device. The composition includes a first finely divided particulate material, and can optionally include at least a second material. The first material is not bioresorbable or is very slowly bioresorbable and the second material or materials are bioresorbable at a higher rate than the first material. The method can optionally include fully inserting the device into the hole or cavity, and can optionally include administering a pharmaceutical composition to the subject.
TISSUE-DERIVED SCAFFOLDING MATERIALS AND METHOD FOR TISSUE FORMATION
In accordance with the method of the present invention, 3D tissue-derived scaffolding materials are made in various formats, including but not limited to hydrogel, sponge, fibers, microspheres, and films, all of which function to better preserve natural extracellular matrix molecules and to mimic the natural tissue environment, thereby effectively guiding tissue regeneration. The method involves incorporating a homogenized tissue-derived suspension into a polymeric solution of synthetic, natural, or hybrid polymers to prepare tissue-derived scaffolds in the aforementioned formats. Such tissue-derived scaffolds and scaffolding materials have a variety of utilities, including: the creation of 3D tissue models such as skin, bone, liver, pancreas, lung, and so on; facilitation of studies on cell-matrix interactions; and the fabrication of implantable scaffolding materials for guided tissue formation in vivo. The tissue-derived scaffolds and scaffolding materials made in accordance with the present invention also provide the opportunity to correlate the functions of extracellular matrix with tissue regeneration and cancer metastasis, for example.
NANOFIBER REINFORCEMENT OF ATTACHED HYDROGELS
Described herein are hydrogels attached to a base with the strength and fatigue comparable to that of cartilage on bone and methods of forming them. The methods and apparatuses described herein may achieve an attachment strength between a hydrogel and a substrate equivalent to the osteochondral junction. In some examples the hydrogel may be a triple-network hydrogel (such as BC-PVA-PAMPS) that is attached to a porous substrate (e.g., a titanium base) with the shear strength and fatigue strength equivalent to that of the osteochondral junction.
Implantable mesh
An implantable mesh including demineralized bone fibers mechanically entangled into a biodegradable or permanent implantable mesh is provided. A method of preparing the implantable mesh is also provided. The method of preparing the implantable mesh includes mechanically entangling demineralized bone fibers with non-bone fibers to form the implantable mesh. The mechanical entanglement of the bone fibers into the implantable mesh is achieved by applying needle punching with barbed needles, spun lacing, entanglement with water jets or air jets or ultrasonic entanglement with ultrasonic waves. A method of implanting an implantable mesh at a target bone tissue site is also provided.
PYRROLO - DIPYRIDINE COMPOUNDS
In one aspect, the invention provides compounds of Formula I Formula Ia, Formula Ib, Formula Ic, and Formula Id and salts, hydrates and isomers thereof. In another aspect, the invention provides a method of promoting bone formation in a subject in need thereof by administering to the subject a therapeutically effective amount of a compound of Formula I, Formula Ia, Formula Ib, Formula Ic, or Formula Id. The present invention also provides orthopedic and periodontal devices, as well as methods for the treatment of renal disease, diabetes bone loss, and cancer, using a compound of Formula I, Formula Ia, Formula Ib, Formula Ic, or Formula Id.

INFUSED FIBERS
A method of making infused bone fibers employs the following steps: cutting or shaving whole bone into bone fibers, washing the bone fibers, demineralizing or decalcifying at least partially the whole bone or bone fibers and infusing the bone fibers with a supernatant of biologic material or a polyampholyte cryoprotectant or a combination of both to create infused bone fibers. The step of infusing includes exposing the bone fibers to a negative pressure or vacuum to draw the supernatant and/or the polyampholyte cryoprotectant into the bone fibers, or alternatively, exposing the demineralized whole bone to a positive pressure to drive the supernatant and/or the polyampholyte cryoprotectant into the bone. The resultant method creates an infused bone grafting composition having bone fibers taken from whole bone, demineralized or decalcified at least partially and infused with one or more of a supernatant of biologic material or a polyampholyte cryoprotectant or both.

In an exemplary embodiment, provided is a fusion strip made of an osteoconductive material and of a dimension that is especially adapted for improved repair of sternal bone defects.
Engineering mechanically functional human cartilage and method of making same
Medical devices having engineered mechanically functional cartilage from adult human mesenchymal stem cells and method for making same.
Pharmaceutical composition and biomaterial comprising fusion peptide in which bone tissue-selective peptide bound to parathyroid hormone (PTH) or fragment thereof
The present invention relates to a pharmaceutical composition for preventing or treating bone diseases comprising a fusion peptide in which a bone tissue-selective peptide bound to parathyroid hormone (PTH) or a fragment thereof. More particularly, the present invention relates to a pharmaceutical composition and biomaterial for preventing or treating bone diseases comprising a fusion peptide in which a bone tissue-selective peptide represented by an amino acid sequence of SEQ ID NO. 3 bound to parathyroid hormone (PTH) or a fragment thereof represented by an amino acid sequence of SEQ ID NO. 4 or 5. The fusion peptide can improve effects of PTH by selectively binding to bone tissue and can reduce administration frequency by increasing the half-life. The fusion peptide can be used as a subcutaneous or intravenous injection-type pharmaceutical composition for treating osteoporosis and fracture, and can be used in combination with a medical device for tissue recovery to increase formation of bone tissue. In addition, when the fusion peptide is bound to the surface of dental and orthopedic medical devices, transplantation stability of the medical device can be improved through improved osseointegration between the medical device and new bone.
Antimicrobial composition for inhibiting microbial organisms in allograft and the method thereof
The present invention is a method for producing allograft tissue by applying an antimicrobial solution to allograft tissue. The antimicrobial solution exhibits antimicrobial activity to make allograft resistant to microbial organisms, such as bacterium.
