The application of matrix metalloproteinase (MMP) inhibitors to the skin inhibits the degradation of proteins found in the skin including collagen, elastin, and other basement membrane and extracellular matrix protein. MMP inhibitors may be used in both cosmetic compositions and pharmaceutical compositions for application to skin. MMP inhibitors are formulated with a cosmetically suitable vehicle or pharmaceutically acceptable excipient for application to the skin as creams, lotions, ointments, solutions, face masks, etc. As cosmetics, the inventive MMP inhibitor compositions are applied to the skin to prevent or reduce the appearance of wrinkles, pigmentation changes, loss of elasticity, or other effects associated with aging or sun damage. As pharmaceuticals, the inventive MMP inhibitor compositions may also be applied to the skin to treat or prevent a skin disease (e.g., proliferative disease, inflammatory disease).

A method for preparing a scaffold material for use in the prosthesis therapy is disclosed. The method comprises (a) lyophilizing a segment of native soft tissue of mammalian origin, heating the lyophilized tissue at a temperature of 100-200° C., and incubating the tissue with elastase to selectively remove elastin leaving the extracellular components mainly comprised of collagen.

Dermal fibroblasts permanently loose their ability to synthesize elastin, the major component of elastic fibers, shortly after puberty. This progressive loss of elastic fibers cannot be replaced, resulting in the physical signs of aging. The present invention provides methods and compositions containing the polyphenols ellagic acid and/or tannic acid for protection against degradation of cutaneous elastic fibers by the elastolytic enzymes. The use of ellagic acid and/or tannic acid increased the overall deposition of elastic fibers in healthy and damaged skin cells. The protection of both intra-tropoelastin and extra-cellular mature elastic fibers from proteolytic enzymes by ellagic acid and tannic acid caused an increase in the net deposition of elastic fibers. Therefore, embodiments of the present invention provide methods and composition for the treatment of skin and prevention and treatment of degradation of dermal elastic fibers.

Topical skin compositions include a complex containing components to provide a defense against the various pathway mechanisms of free radicals, reactive oxygen species, reactive nitrogen species, and other oxidizing species on the human body including the skin. The compositions may be administered by topically applying them in an amount to inhibit those mechanisms. The compositions and methods are directed to the prevention of the adverse or detrimental effects of free radicals, reactive oxygen species, reactive nitrogen species, and other oxidizing species on the human body including the skin. Thus, the compositions according to the invention improve barrier function, inhibit elastase and collagenase, and/or promote synthesis of collagen and elastin.

Biocompatible materials for use in vascular applications or for implantation have been engineered, combining human recombinant tropoelastin with other synthetic or natural biomaterials to form protoelastin. The materials can be in the form of elastin films on metal or polymer substrates, laminates of alternating polymer and elastin, blends of polymer and elastin, or elastin crosslinked with or tethered to polymer or metal. These are mechanically stable, elastic, strong and biocompatible (i.e., not thrombogenic and promoting adhesion of cells, especially human endothelial cells), not eliciting a foreign body response. Plasma polymerization of substrate is shown to enhance biocompatibility, especially when used to bind elastin or other protein to the substrate.

The method for discriminating between benign and malignant prostate tumors relates to analyzing samples of blood, urine and tissue by fluorescence spectroscopy in order to detect the presence of naturally occurring molecules in the fluids and tissue that serve as biomarkers indicative of cancer in the human body. The analysis can be carried out based on fluorescence emission spectra, fluorescence excitation spectra and synchronous (emission and excitation) spectra of bio-samples. The detection, diagnosis, and follow-up and also discrimination between malignant and benign prostate tumors may be made by comparison of ratios of fluorescence emissions and/or excitation intensities of tryptophan, tyrosine, elastin, collagen, bile pigments, NADH, flavins and various species of porphyrins.

A topical composition and method for its use for reducing sagging or wrinkles in the neck area of human skin. The composition includes safe and effective amounts of a mild topical astringent (such as Camphor) for skin tightening, a topical antispasmodic (such as benzaldehyde or benzyl cinnamate) for skin smoothing, and a topical skin irritant to increase localized skin circulation. The composition can also optionally include palmitoyl oligiopeptides to stimulate production of collagen and elastin in skin, a mushroom or plant leaf ferment extract to increase the cell turnover rate skin, and to increase hydration, skin firmness and elimination of fine facial lines, a cocao ferment extract to inhibit lipid peroxidation, inhibit excess ornithine decarboxylase activity, and stimulate cutaneous blood flow to reduce lines and wrinkles, and a Lactobacillus lysate extract to stimulate collagen production. These ingredients are mixed in a dermatologically acceptable carrier for topical application.

The present invention provides compositions for the therapeutic and/or cosmetic treatment of Elastin comprising tissues. Therapeutic and cosmetic compositions comprising an elastin digest stimulate the endogenous production of Elastin and appear to enhance the elasticity of the skin and provide an external supply of peptide precursors of Elastin that penetrate into the tissue to which it is applied. The present invention describes compositions containing an elastin digest derived from proteolytic digestion of insoluble elastin derived from mammalian ligaments with a protein digesting composition, such as proteinase K. The elastin digest is a mixture of elastin peptides wherein the elastin peptide mixture comprises peptides of the sequence GXXPG, wherein X represents one of the natural amino acids. The elastin digest of the present invention may also comprise epitopes of cytokines, growth factors and di-peptides. Methods of using these elastin digest comprising compositions for treating tissues in need of increased elasticity and or Elastin are described.

The present invention provides cosmetic formulations for improving the appearance of the skin, including the facial area. The compositions of the invention provide multiple enhanced technologies that work synergistically to enhance hydration and appearance of the skin. Anti-aging peptides and tissue respiratory factor work together in an HA rich environment to enhance collagen and elastin while beneficial antioxidants protect HA in the skin from damaging exposure.
