  • Publication number: 20030143234
    Abstract: The present invention is based on the discovery of a composition that provides targeted anti-microbial effect. Specifically the composition contains a targeting moiety which recognizes a target microbial organism and an anti-microbial peptide moiety which has anti-microbial activity. In addition, the present invention provides methods of treating a microbial infection, e.g., on mucosal surfaces by using the compositions provided by the present invention.

  • Publication number: 20020068066
    Abstract: Dental caries in man may be prevented or treated by oral ingestion of human or humanized murine monoclonal IgG and IgM antibodies that bind to surface antigens of cariogenic organisms, such as S. mutans. The genetically engineered monoclonal antibodies engage the effector apparatus of the human immune system when they bind to cariogenic organisms, resulting in their destruction. In a preferred embodiment, monoclonal antibodies to cariogenic organisms are produced by edible plants, including fruits and vegetables, transformed by DNA sequences that code on expression for the desired antibodies. The antibodies are applied by eating the plants.

  • Patent number: 6231857
    Abstract: The invention describes three monoclonal IgG antibodies, referred to as SWLA1, SWLA2, and SWLA3, which appear to recognize a species-specific lipooligosaccharide or lipopolysaccharide on the cell surface of S. mutans. The invention also describes a rapid method of detection of S. mutans without the need for prior growth of the bacteria in culture. The invention further describes a methods of utilizing these antibodies for rapidly quantitatively detecting S. mutans. These methods are sensitive enough to detect the presence of a single S. mutans bacterial cell. These methods can be widely used in the clinical diagnosis and treatment of dental caries in humans.

  • Patent number: 6210562
    Abstract: A catalytic pyrolysis process for production of ethylene and propylene from heavy hydrocarbons, comprises that heavy hydrocarbons are contacted with a pillared interlayered clay molecular sieve and/or phosphorus and aluminum or magnesium or calcium modified high silica zeolite having a structure of pentasil contained catalysts in a riser or downflow transfer line reactor in the presence of steam and catalytically pyrolysed at a temperature of 650° C. to 750° C. and a pressure of 0.15 to 0.4 MPa for a contact time of 0.2 to 5 seconds, a weight ratio of catalyst to feedstock of 15:1 to 40:1 and a weight ratio of steam to feedstock of 0.3:1 to 1:1. The yields of ethylene and propylene by the present invention are over 18 wt %.
