Methods are provided for regulating bone remodeling or tooth movement, comprising allowing a functional appliance to exert a force on oral or maxillofacial bone, muscle, or soft tissue, or one or more teeth of a patient in need thereof; and administering an effective amount of light to the oral or maxillofacial bone, muscle, or soft tissue, or one or more teeth, wherein the light is administered before, during, or after the force is exerted. Methods are also provided for regulating bone remodeling, comprising administering an effective amount of vitamin D to an oral or maxillofacial bone, muscle, or soft tissue, or to one or more teeth of a patient in need thereof; and administering an effective amount of light to the oral or maxillofacial bone, muscle, or soft tissue, or to the one or more teeth. Apparatuses useful for providing light therapy and / or vitamin D is also provided.

This invention relates, in part, to unique and newly identified genetic polynucleotides involved in the process of bone remodeling; variants and derivatives of the polynucleotides and corresponding polypeptides; uses of the polynucleotides, polypeptides, variants and derivatives; and methods and compositions for the amelioration of symptoms caused by bone remodeling disorders. Disclosed in particular are, the isolation and identification of polynucleotides, polypeptides, variants and derivatives involved in osteoclast activity, validation of the identified polynucleotides for their potential as therapeutic targets and use of the polynucleotides, polypeptides, variants and derivatives for the amelioration of disease states and research purposes.

The present invention relates to pyridines or pyrazines that inhibit kinases. In particular the compounds of the invention inhibit members of the class III PTK receptor family such as FMS (CSF-IR), c-KIT, PDGFRβ, PDGFRα or FLT3 and KDR, SRC, EphA2, EphA3, EphA8, FLT1, FLT4, HCK, LCK, PTK5 (FRK), SYK, DDR1 and DDR2 and RET. The compounds of the invention are useful in the treatment of kinase associated diseases such as immunological and inflammatory diseases; hyperproliferative diseases including cancer and diseases involving neo-angiogenesis; renal and kidney diseases; bone remodeling diseases; metabolic diseases; and vascular diseases.

A device for treating a bone includes a first clamp member sized and shaped to be mounted over a bone laterally across a fixation plate positioned along a length of the bone. In addition, the device includes a second clamp member coupleable to the first clamp member so that, when the first and second clamp members are coupled together in an operative position, the first and second clamp members extend about at least a portion of a periphery of the bone. The second clamp member includes a spring feature biased toward an initial configuration and deflectable toward a second configuration away from the bone.

An intramedullary nail for fixation and stabilization of a fractured bone that also allows for a controlled amount of longitudinal motion at the fracture site to encourage bone remodeling and healing is described. The intramedullary nail has a proximal portion and a distal portion that are coupled together in a manner by a biasing assembly that provides for a controlled movement of the proximal and distal portions relative to each other so that when a patient puts pressure on the bone, such as when walking, the fracture site compresses and the bone ends move together, and when the pressure is released from the bone, the bone ends are biased apart by a controlled amount.

The invention relates to a mineralized collagen / high molecule composite porous bone material and a preparation method thereof. The preparation method comprises the following steps that a collagen solution is prepared; a calcium-ion-containing aqueous solution is added; a phosphate-radical-ion-containing aqueous solution is added; the pH value is adjusted to be 8; a precipitate is washed, and suction filtration is conducted; freeze-drying is conducted; through grinding, dry mineralized collagen powder is prepared; a high molecule polymer solution is prepared; a polymer / calcium phosphate salt / collagen mixed solution is prepared; freeze-drying is conducted; ultrasonic suction and drying are conducted; sterilization is conducted, and accordingly the mineralized collagen-high molecule compositeporous bone material is prepared. The preparation method has the advantages of being low in cost, high in material utilization rate, easy to implement and the like, and the mineralized collagen-highmolecule composite porous bone material prepared through the method has the advantages of being high in homogeneity and mechanical strength, long in degradation time, low in organic solvent residue content, high in porosity, good in biocompatibility, capable of achieving cooperation of degradation time and bone remodeling and the like.

The present invention concerns an orthodontic appliance for accelerating the tooth aligning effect and shortening the treatment period, and has an object to provide an appliance which can bring about higher aligning effect than usual ways by giving vibration to tooth to be aligned to activate bone remodeling of the targeted tooth and the alveolar bone and enhance the shift of the tooth. This appliance includes a vibrating element and a dental mouthpiece having the vibrating element built therein. The provision of the vibrating element in the dental mouthpiece facilitates the application of vibration and handling, and continues the treatment safely even at home. The inner shape of the dental mouthpiece serves aligning treatment as well as acceleration of the effect.

A method for in vivo, ex vivo and in vitro regeneration of cartilage and collagen. In vivo, ex vivo and in vitro regeneration and de novo formation of articular cartilage and collagen by intermittently applied hydrostatic pressure. The application of external interval loading consisting of repeated periods of applied hydrostatic pressure followed and interrupted by periods of recovery. The application of the intermittent hydrostatic pressure at physiological levels 5-10 MPA for an interval of 4 hours followed by a recovery period up to about 20 hours, said pressure applied to the cartilage cells in vitro, explants of cartilage ex vivo and in vivo to cartilage that remains intact within te joint space of diarthrotic joints. The interval loading results in the selective inhibition of matrix degrading enzymes, pro-inflammatory cytokines and chemokines that attract inflammatory cells into the joint cavity and in selective decrease of gene expression of growth factors that are inhibitory to type II collagen expression.
