Abstract: The present invention is directed to a delayed release pharmaceutical composition in solid dosage form comprising a core comprised of a therapeutically effective amount of drug, e.g., mesalamine, and a pH sensitive coating comprising a mixture of two different pH sensitive polymers, the first pH sensitive polymer dissolves in an aqueous solution at a pH of about 7 or greater and the second pH sensitive polymer dissolves in an aqueous solution at a pH of about 6 or greater, wherein the weight ratio of the first pH sensitive polymer to the second pH sensitive polymer ranges from about 2:1 to about 4:1 and the percent weight gain resulting from the addition of the pH sensitive coating ranges from about 8% up to and including 15% by weight of the core, including any subcoating.

Abstract: Novel human monoclonal antibodies derived from a transgenic mouse are disclosed as well as a process for the preparation of the novel monoclonals and a therapeutic method of treating an individual for hemolytic uremic syndrome or of protecting an individual against hemolytic uremic syndrome by administration of the monoclonals to the individual in need of treatment or protection.

Abstract: Human and humanized monoclonal antibodies which binds specifically to subunit A of Shiga like toxin II have been developed which are effective to prevent or ameliorate one or more symptoms of HUS in a human. Effective dosages for treatment or prevention range from approximately 0.1 to 5.0 mg of antibody/kg of patient weight. The examples demonstrate the preferred dosage ranges based on the pig model, and what is being tested in phase I clinical trials. Antibodies are preferably transfused over a period of two hours, although this will depend on the patient and the disease state at the time of treatment. Preferred dosages for treatment of humans are between 0.1 mg/kg-5.0 mg/kg of 5C120, or an equivalent dosage of another antibody to subunit A of STX2. In the most preferred embodiments, dosages of 0.1 mg/kg, 0.5 mg/kg, or 5.0 mg/kg of 5C12 (low dose, anticipated therapeutic dose based on animal data and high dose) are administered.

Abstract: Proteins having chorismate mutase-prephenate dehydratase (CMPD) activity, but lacking phenylalanine sensitivity are produced by genetic engineering. The proteins contain a sequence substantially corresponding to the N-terminal 337 amino acids of Escherichia coli CMPD. Expression vectors including genes coding for those proteins and regulatory DNA enabling their expression are used to transform host microorganisms, which are cultured to produce phenylalanine.

Abstract: An Escherichia coli chromosomal DNA segment is engineered for controllable excision and loss from the E. coli cell population. The DNA segment has a gene determining a function that is lost in the absence of that chromosomal segment. Specifically, the segment includes a pair of lambdoid phage att sites positioned at opposite ends thereof, and a gene encoding the function. The E. coli cell includes DNA encoding lambdoid phage int and xis, positioned for transcription under control of an external stimulus. By excising the chromosomal DNA segment once a desired cell population is achieved, cell growth and diversion of intermediates from a desired fermentation product are diminished or avoided.
