  • Patent number: 8791068
    Abstract: A novel group of gastrokines called Gastric Antrum Mucosal Protein is characterized. A member of the group is designated AMP-18. AMP-18 genomic DNA, cDNA and the AMP-18 protein are sequenced for human, mouse and pig. The AMP-18 protein and active peptides derived from it are cellular growth factors. Surprisingly, peptides capable of inhibiting the effects of the complete protein, are also derived from the AMP-18 protein. Cytoprotection and control of mammalian gastro-intestinal tissue growth and repair (restitution) is facilitated by the use of the proteins, making the proteins candidates for therapies in inflammatory bowel disease and gastric ulcers.

  • Patent number: 8383851
    Abstract: The present invention involves a new synthesis route for the formation of lactylates. The method comprises reacting a dilactide with a compound comprising a hydroxy group. This reaction is preferably carried out in the presence of a cation or other source of alkalinity. Preferred compounds comprising a hydroxy group include any fatty acid and fatty acid alcohol (particularly C1-C26 fatty acid chains). Preferred cations include cations of Group I and II metals, with sodium, calcium, and potassium cations being particularly preferred. The inventive reactions proceed much more rapidly than prior art lactylate synthesis reactions, and can be used to form 1-, 2-, 3-, 4-, and 5-lactylates.

  • Publication number: 20070129303
    Abstract: Novel growth peptides derived from protein factors having molecular weights of about 22 and 45 kDa stimulate mitogenic activity of epithelial, but not fibroblastic cells, in particular, kidney epithelial cells. A source of the factors is scrape-wounded kidney epithelial cells in culture. Synthetic peptides having sixteen amino acids or less, in particular a hexapeptide, YPQGNH (SEQ ID NO: 2) maintain the mitogenic activity. The peptide AQPYPQGNHEASYG (14-Ser) (SEQ ID NO: 15) is effective in reversing acute renal failure in animals. The growth-promoting characteristics of the 22 and 45 kDa proteins and the peptides are useful in treating and diagnosing patients with kidney disease. Nucleotide sequences that encode the factor are useful to develop probes to locate similar factors, to identify genetic disorders involving the factor, and to produce the factor by genetic recombinant methods. The nucleotide sequences and fragments thereof, are also useful for diagnosis and treatment of kidney disorders.

  • Patent number: 5496071
    Abstract: The objective of the invention is to an identity format provided in each article for enabling search and classification. In a mass distributable print media containing at least one page and a plurality of articles on the page, each article including a title and related text, an improvement includes a range of elements including but not limited to a relative subject matter index number, complete date of publication and publisher name for the print media arranged closely adjacent each article. All or some of these elements may be supplemented by machine readable code such as a bar code. Publishers of newspapers, magazines and the like have not heretofore provided these elements on every article.

  • Patent number: 5476922
    Abstract: Autocrine growth factors and isoforms of those factors have been identified, isolated, purified and manipulated. Nucleic acid segments coding for the factors, and antibodies directed to the factors are also aspects of the present invention. The effect of these growth factors on cells is to enhance their growth by increasing mitogenesis. In particular, the growth factors stimulate kidney epithelial cell growth. The growth factors differ from others previously reported in their molecular weights and other properties, for example, resistance to denaturation by dithiothreitol. Methods of preparation and use of the factors are also described. The growth factors are released from kidney epithelial cells by short exposures to a low-sodium environment. The factors have potential for treatment of kidney disease.
