摘要:
Methods of expressing LIM mineralization protein in non-osseous mammalian cells, such as stem cells or intervertebral disc cells (e.g., cells of the annulus fibrosus, or cells of the nucleus pulposus) are described. The methods involve transfecting the cells with an isolated nucleic acid comprising a nucleotide sequence encoding a LIM mineralization protein operably linked to a promoter. Transfection may be accomplished ex vivo or in vivo by direct injection of virus or naked DNA, or by a nonviral vector such as a plasmid. Expression of the LIM mineralization protein can stimulate proteoglycan and/or collagen production in cells capable of producing proteoglycyan and/or collagen. Methods for treating disc disease associated with trauma or disc degeneration are also described.
摘要:
Methods of inducing the expression of a proteoglycan such as aggrecan in a cell are described. A method is described which includes transfecting a cell with an isolated nucleic acid comprising a nucleotide sequence encoding a LIM mineralization protein operably linked to a promoter. The LIM mineralization protein can be rLMP, hLMP-1, hLMP-1s, or hLMP-3. Transfection maybe accomplished ex vivo or in vivo by direct injection of virus or naked DNA, or by a nonviral vector such as a plasmid. The method can be used to induce proteoglycan synthesis in osseous cells or to stimulate proteoglycan and/or collagen production in cells capable of producing proteoglycan and/or collagen (e.g., intervertebral disc cells including cells of the nucleus pulposus and annulus fibrosus).

摘要:
The present invention relates to the methods and compositions for the treatment of subjects having compromised bone conditions. Specifically, the invention relates to combinatorial therapeutic strategies including small molecules and peptide mimics of LIM mineralization proteins, particularly LMP-1, to overcome the dose-related translational barriers for BMP-2 therapeutics.

Methods of expressing LIM mineralization protein in mammalian cells are described. Methods of expressing LIM mineralization protein and assessing glycosylation of the LIM mineralization protein in prokaryotic and non-mammalian eukaryotic cells are also described. The methods involve transfecting the cells with an isolated nucleic acid comprising a nucleotide sequence encoding a LIM mineralization protein. Transfection may be accomplished in vitro, ex vivo or in vivo by direct injection of virus or naked DNA, or by a nonviral vector such as a plasmid.

摘要:
Effective treatments of acute pain for extended periods of time are provided. Through the administration of an effective amount of dexamethasone at or near a target site, one can relieve pain cause by diverse sources, including but not limited to spinal disc herniation (i.e. sciatica), spondilothesis, stenosis, discongenic back pain and joint pain as well as pain that is incidental to surgery. When appropriate formulations are provided within biodegradable polymers, this relief can be continued for at least twenty-five days. In some embodiments, the relief can be for at least fifty days, at least one hundred days, at least one hundred and thirty-five days or at least one hundred and eighty days.
摘要:
The present invention relates to the design and composition of a depot implant for optimal delivery of growth factors to treat osteoporotic bone, in that such depot implant is constructed to be in a cylinder (rod) or sphere shape and have a natural or synthetic polymer scaffold with or without impregnated calcium phosphate particles. The density of the depot is higher than a typical BMP sponge carrier to facilitate it's implantation and slower release of the growth factor. The scaffold is such that it has adequate porosity and pore size to facilitate growth factor seeding and diffusion throughout the whole of the bone structure resulting in increased bone mineral density in the osteoporotic bone. In addition, the shape of the depot implant allows for delivery through a cannula or large bore needle.
摘要:
Described is a medically useful article comprising a three-dimensional body including one or more implantable substances, wherein the body defines one or more reservoirs for receiving amounts of a biocompatible wetting liquid. In certain embodiments the body is disruptable upon wetting with the biocompatible liquid to form a conformable implantable material such as a putty, paste or more flowable wetted implant material. Also described are methods for manufacturing such medical materials, and methods for using such medical materials to treat patients.
摘要:
A brush for hygienic purposes includes a handle with a lower and an upper portion and a head. The upper portion is sized and shaped to capture the head. Preferably the head is a removable cartridge and includes a flexible base with a plurality bristles and a pad with holes disposed over the bristles. The pad could be a foam or sponge matrix or could be a stack of sheets removable one at a time. Upper portion of the handle is curved to provide a predetermined shape to the head. Optionally, a vibrating device is incorporated in the brush so that the brush can be used as to massage the skin or scalp.
