Patent number: 7345022Abstract: Novel peptides are disclosed that may be used as inhibitors of amyloidogenesis, as suppressors of amyloid toxicity, and as therapeutic agents for amyloid-associated diseases such as Alzheimer's disease, Parkinson's Disease, Creutzfeldt-Jakob Disease, Huntington's Disease, and Type II Diabetes. These new ?-strand mimics (?-sheet “blockers”), containing C?,?-disubstituted amino acids, specifically interact with and block the development of the ?-sheet structure of the developing fibrils of amyloid diseases, such as Alzheimer's disease amyloid ?-peptide (A?). We have discovered that oligomerization of ?-sheet structures, including those implicated in amyloid-associated diseases, may be inhibited or even reversed by the presence of extended peptide structures that have only one edge available for hydrogen bonding. Without a second edge that is also available for hydrogen bonding, the extension of a developing ?-sheet is blocked by binding to the novel peptides.Type: GrantFiled: September 18, 2003Date of Patent: March 18, 2008Assignee: Board of Supervisors of Louisiana State University and Agricultural and Mechanical CollegeInventors: Robert P.

Patent number: 7345026Abstract: H-2 class I negative, HLA-A2.1 transgeniic HHD mice were used for a comparative evaluation of the immunogenicity of HLA-A2.1 restricted human tumor-associated CTL epitopes. A hierarchy was established among these epitopic peptides injected into mice in IFA which correlates globally with their capacity to bind and stabilize HLA-A2.1 molecules. Co-injection of a helper peptide enhanced most CTL responses. In contrast, classical HLA class I transgenic mice which still express their own class I molecules did not, in most cases, develop H.A.-A2.1-restricted CTL responses under the same experimental conditions. Different monoepitopic immunization strategies of acceptable clinical usage were compared in HHD mice. Recombinant Ty-virus-like particles, or DNA encoding epitopes fused to the hepatitis B virus middle envelope protein gave the best results. Using this latter approach and a melanoma-based polyepitope construct, CTL responses against five distinct epitopes could be elicited simultaneously in a single animal.Type: GrantFiled: March 14, 2003Date of Patent: March 18, 2008Assignee: Institut PasteurInventors: Hüseyin Firat, François Lemonnier, Pierre Langlade-Demoyen, Marie-Louise Michel, Andreas A.

Patent number: 7345029Abstract: The present invention relates to a solution for peritoneal dialysis, consisting of at least two single solutions which are combined after a heat sterilization and are administered to a patient, the first single solution containing an osmotic and the second single solution containing a buffer, and one of these single solutions or another single solution containing electrolyte salts. The avoidance of a glucose-like degradation as well as hydrolysis during sterilization and storage while maintaining a neutral mixture pH is achieved according to the invention by the osmotic comprising a glucose polymer and/or glucose polymer derivative, and the pH of the first single solution being between 3.5 and 5.0. The present invention further relates to a twin-chambered pouch consisting of a plastic pouch with at least one first chamber and a second chamber, the first single solution being included in the first chamber and the second single solution being included in the second chamber.Type: GrantFiled: April 18, 2003Date of Patent: March 18, 2008Assignee: Fresenius Medical Care Deutschland GmbHInventor: Thomas Zimmeck
