摘要:
Compositions of foods, vitamin and mineral supplements, topical or oral drugs, and cosmetic products containing a small peptide or peptides for slowing degradation, for example by transition metals. The peptides are di, tri, terra-, and/or penta-peptides containing two or more aspartic acid residues. The degradation of several of the vitamin and other constituents vitamin-mineral supplements can be considerably slowed by composition incorporating such peptides, particularly if soluble (and thus bioavailable) forms of copper and/or iron are also present. The peptides can be hydrolyzed by the normal digestive process thus releasing bound metals. Multiple aspartate peptide(s) compositions with foods, topical or oral drugs, cosmetic, and hair care products can replace synthetic chelating preservative agents. Methods are also described to effectively slow degradation and preserve the above products using multiple aspartate peptides.

摘要:
A method for determining a tissue degradation process by detection of fibromodulin neoepitopes, antibodies against fibromodulin neoepitopes and fragments and peptides containing fibromodulin neoepitopes for generation of such antibodies are described. The method for determining a tissue degradation process comprises detecting in a sample the presence of one or more neoepitopes of mammalian fibromodulin that appear after cleavage of fibromodulin at one or more sites between position 20 and 90. The invention also relates to methods for measuring enzymatic cleavage of fibromodulin and for inhibiting the cleavage of fibromodulin. Furthermore, the invention relates to medical use of compounds inhibiting cleavage of fibromodulin.
