Abstract: The present invention relates to ent-19-Norprogesterone, compositions and methods of use thereof to treat, minimize and/or prevent traumatic brain injury (TBI), including severe TBI, moderate TBI and mild TBI, including concussions.

Abstract: The invention provides methods and compositions for regulating weight and size in animals.

Abstract: The invention provides improvements of lantibiotics useful for reducing the numbers of microbes or the reproduction of microbes in or on subjects or objects. One embodiment of the invention provides variants of antibiotics wherein the amino acid at position (1) is changed to Ile or Gly, the amino acid at position (4) is changed to an Ala, the amino acid at position (4) is removed, the amino acid at position (5) is changed to an Ala, or wherein, as in the case of MU1140, the amino acid at position (13) is Arg, the Arg at position (13) is substituted with Asp, or combinations of two or more these changes or a pharmaceutically acceptable salt thereof.

Abstract: The invention provides recombinant Streptococcus mutans strains that can be used to improve oral health. An embodiment of the invention provides a method of reducing the incidence or severity of dental caries in a dental caries-susceptible host comprising administering orally to the host an isolated recombinant S. mutans strain of the invention in an amount effective for replacement of dental caries-causing S. mutans host strains in the oral cavity of the host. The isolated recombinant S. mutans strain 10 can be contained in a mouthwash, toothpaste, chewing gum, floss, chewable tablet, food, or beverage.

Abstract: The invention provides compositions comprising one or more isolated LDH-deficient mutans streptococcus strains and one or more isolated S. oralis strains and/or one or more isolated S. uberis strains. Compositions of the invention are useful to maintain oral health, by for example treating and/or preventing one or more symptoms of dental caries, periodontitis and/or other oral cavity diseases or wounds.

Abstract: Disclosed are methods for obtaining antigens that are expressed by pathogenic microorganism during an infection process, as well as the antigens so obtained. Also disclosed are isolated polynucleotides encoding said antigens, recombinant polypeptides expressed from the isolated polypeptides, antibodies capable of forming immune complexes with the obtained antigens, and various other compositions useful in the detection, diagnosis, prevention and/or treatment of a microbial infection. The methods of the invention utilize pooled sera from patients who have partly or completely undergone infection by a microbial organism in order to obtain genes that are expressed during in vivo but not during in vitro growth of the microbial organism.

Abstract: The invention provides methods of identifying proteins and polypeptides and their cognate polynucleotides that are expressed by cells under one environmental condition and not under a second environmental condition. The invention also provides compositions for the treatment and detection of cancer, including colorectal cancer.

Abstract: The invention provides compositions comprising one or more isolated LDH-deficient mutans streptococcus strains and one or more isolated S. oralis strains and/or one or more isolated S. uberis strains. Compositions of the invention are useful to maintain oral health, by for example treating and/or preventing one or more symptoms of dental caries, periodontitis and/or other oral cavity diseases or wounds.

Abstract: The present invention provides a method of synthesizing an intramolecularly bridged polypeptide comprising at least one intramolecular bridge. The present invention further provides a method of synthesizing an intramolecularly bridged polypeptide comprising two intramolecular bridges, wherein the two intramolecular bridges form two overlapping ring, two rings in series, or two embedded rings. The present invention also provides methods for synthesizing lantibiotics, including Nisin A. Additionally, the invention provides intramolecularly bridged polypeptides synthesized by the methods disclosed herein and differentially protected orthogonal lanthionines.
