  • Patent number: 8198058
    Abstract: The invention provides methods for producing methanol, higher alcohols (containing 2 or more carbons), in particular ethanol, or diesel fuel from biological wastes such as manure, sewage, and crop wastes, as well as from other organic materials. In the methods, organic material is first fermented by anaerobic microorganisms to a biogas consisting primarily of methane and carbon dioxide. The biogas is then converted to synthesis gas consisting primarily of CO and H2. The synthesis gas is then contacted with a liquid fuel production catalyst to synthesize higher alcohols or other liquid fuels. The invention involves converting CO2 in the biogas to synthesis gas by combining a CO2 reforming reaction with steam reforming or partial oxidation to convert the biogas to synthesis gas. The invention also provides methods involving recirculating CO2 from the output of the liquid fuel production reaction to one or more of the fermentation reaction, the CO2 reforming reaction, or the liquid fuel production reaction.

  • Patent number: 8124728
    Abstract: The CA125 gene has been cloned. The CA125 molecule comprises three major domains: an extracellular amino terminal domain; a large multiple repeat domain; and a carboxy terminal domain which includes a transmembrane anchor with a short cytoplasmic domain. Additionally, an amino terminal extension is present. The molecular structure is dominated by a repeat domain comprising more than sixty 156-amino-acid repeat units The repeat units encompass an interactive disulfide bridged C-enclosure and the site of OC125 and M11 binding. The CA125 molecule is anchored at its carboxy terminal through a transmembrane domain and a short cytoplasmic tail. The structure has potential for use as a new gold standard for detecting the CA125 antigen, and can provide a basis for the development of a vaccine useful for the treatment of ovarian cancer and other carcinomas where CA125 is elevated.

  • Patent number: 8097242
    Abstract: TADG-12 and CA125 are two proteins expressed with high specificity in ovarian cancer tumors. They thus would be potential antigens for immunotherapy in ovarian cancer. The invention is based on the discovery of peptides in TADG-12 and CA125 that can be used to induce an autologous T cell response that lyses ovarian cancer cells expressing TADG-12 or CA125. The peptides are contacted with dendritic cells in vitro to generate peptide-loaded dendritic cells. The peptide-loaded dendritic cells are contacted with T cells in vitro to amplify CD8+ T cells that recognize the peptide. At least one CA125 peptide and at least one TADG-12 peptide were found that amplified CD8+ T cells, even from cancer patients, that lysed autologous CA125-expressing or TADG-12-expressing tumor cells. The peptide-loaded dendritic cells can be administered to a cancer patient to amplify CD8+ T cells in vivo that attack the cancer cells.

  • Patent number: 8021672
    Abstract: The invention involves the discovery that Chlamydia sp. strains can be cured of their plasmids by treatment with novobiocin, and that plasmid-deficient strains are defective in infecting cells under standard conditions, but can infect cells if centrifuged onto the host cells. But it is found that plasmid-deficient strains with wild-type infection efficiency under standard conditions can be isolated as mutants from parent plasmid-deficient strains with low infectivity by selecting for infection under standard conditions. Both the less infective and the highly infective plasmid-deficient strains were able to infect mice with little or no pathological symptoms, and both reduced the pathology in mice later challenged with the parental wild-type disease-causing Chlamydia strain. Thus, plasmid-deficient Chlamydia are effective vaccine strains. The invention provides a process for isolating a plasmid-deficient strain of Chlamydia sp., a process for developing a plasmid-deficient strain of Chlamydia sp.

  • Patent number: 8016700
    Abstract: The invention provides a new tennis backboard design. The backboard includes a firm backing layer underlying a soft deadening layer. The rebound of a tennis ball from the backboard is reduced as compared to rebound from a rigid hard-surface backboard. This allows a player to stand fairly close to the backboard, which reduces misses. The player can stand fairly close and hit balls hard against the backboard. Because the rebound is reduced, the ball simply bounces back softly and easily to the player, allowing the player to hit hard again from a fairly short distance. Thus, long rallies without missing are easily achieved. Since the bounce is reduced, the player can stand closer to the backboard, and therefore the backboard can be smaller than conventional backboards without the player missing the backboard. This allows the backboard to be light, portable, and easily stored.

  • Patent number: 7919290
    Abstract: The invention provides a method to decrease emission of carbon dioxide from combustion of fossil fuels or other hydrocarbons and to enhance the efficiency of methane production from anaerobic biodigesters. The invention involves feeding carbon dioxide from the exhaust gas of hydrocarbon fuel combustion to an anaerobic biodigester where biomass is anaerobically fermented to produce methane. Carbon dioxide is an electron acceptor for anaerobic fermentation, and thus some of the carbon dioxide is reduced to methane, which can again be used for fuel. In this way, at least a portion of the exhaust gas CO2 is recycled to form fuel methane instead of being released into the atmosphere. Thus, the net CO2 emission from burning a given amount of fossil fuel is decreased. Adding carbon dioxide to an anaerobic fermentation also increases the efficiency and amount of methane production in the fermentation.

  • Patent number: 7851175
    Abstract: The invention provides methods and kits for characterizing the activity of an acetyl transferase or deacetylase. The method involves enzymatically acetylating or deacetylating in vitro a substrate that is a peptide fragment of a full-length polypeptide, and then non-enzymatically acylating the peptide substrate with acyl groups that differ in molecular weight from the enzymatically added or removed acetyl groups. Typically, deuterated acetic anhydride is used to non-enzymatically acylate the substrate. The fully acylated substrate is then characterized by mass spectrometry to determine the amino acid positions of the substrate that are enzymatically acetylated or deacetylated.

  • Patent number: 7846446
    Abstract: The invention involves peptides of from about 7 to about 50 amino acid residues in length that have epitopes that bind to more than one HLA class II protein and stimulate CD4+ T cells for treatment of cancer from one of three serine proteases overexpressed in ovarian cancer and other cancers—stratum corneum chymotryptic enzyme, matriptase, and hepsin. Since the peptides bind to more than one HLA class II protein variant, they can be used to treat cancer in most patients of a population having a variety of HLA class II alleles. The peptides can be loaded onto autologous dendritic cells of a cancer patient and infused into the patient to activate a CD4+ and CD8+ T cell response that recognizes tumor cells expressing the peptide antigen.
