Abstract: The present invention relates to processes to make neosaxitoxin, and analogues and variants thereof, and intermediates in the production of neosaxitoxin in recombinant host cells. Neosaxitoxin and the analogues and variants thereof may be used in the production of pharmaceutical compositions.

Abstract: A method of screening multiply transformed/transfected cells to identify those cells expressing at least two peptides or proteins of interest. The method comprising: 1. Simultaneously or sequentially transforming a cell with at least two different expression cassettes in which the gene of interest is linked via an IRES to a fluorescent marker gene. Each marker gene is different. 2. Providing conditions in which expression of the genes will occur. 3. Identifying cells expressing proteins by detecting the different fluorescent signals.

Abstract: An isolated polypeptide and immunogenic fragments thereof are described together with their variants and derivatives as novel immunogenic agents for treating or preventing Helicobacter infection in a mammalian host. The polypeptide comprises a C-terminal portion of a Helicobacter catalase, which portion lacks significant amino acid sequence identity with human catalase, wherein the polypeptide is other than full-length Helicobacter catalase.

Abstract: Method of enhancing a resident population of microorganism in a selected site of the gastrointestinal tract of an animal, the method comprising providing to the animal a selected modified or unmodified resistant startch or mixtures thereof in combination with one or more probiotic microogranisms such that upon ingestion the starch passes through the gastrointestinal tract substantially unutilized until it reaches the selected site where it is utilised by the resident and/or the probiotic microogranisms thereof causing an increase in number and/or activity of the microogranisms.

Abstract: A method of and apparatus for controlling the speed of a rotary blood pump, which comprises the measuring the speed and/or power of said pump, calculating an array of system parameters derived from the measured speed, analysing these parameters, and if the analysis indicates ventricular collapse or imminent ventricular collapse, then the speed of said pump is altered, to minimise the risk of the collapse occurring. Preferably the analysis is done using a Classification and Regression Tree (CART) analysis.

Abstract: Protective Helicobacter antigens, especially H. pylori antigens, and the use of these antigens for the treatment of or prevention of, gastroduodenal disease associated with H. pylori infection.

Abstract: An antigenic preparation for use in the treatment or prevention of Helicobacter infection in a mammalian host, comprises the catalase enzyme of Helicobacter bacteria, particularly the catalase enzyme of H. pylori or H. felis, or an immunogenic fragment thereof.

Abstract: Improved method of enhancing a population of one or more target micoorganisms in the gastrointestinal tract of an animal, the improvement comprising providing to the animal a selected modified or unmodified resistant starch or mixtures thereof, such that the one or more microorganisms will selectively utilize the starch and/or increase in number and/or activity in the gastrointestinal tract, either uniformly throughout the gastrointestinal tract or at specific site or regions.

Abstract: The application discloses a method for the treatment of Heliobacter infection in a mammalian host, which comprises administration to said infected host of an immunologically effective amount of one or more Heliobacter antigen(s), optionally in association with a mucosal adjuvant.

Abstract: Probiotic composition comprising one or more probiotic microorganisms, a carrier which will function to transport the one or more probiotic microorganisms to the large bowel or other regions of the gastrointestinal tract of an animal, the carrier comprising a modified or unmodified resistant starch or mixtures thereof, which carrier acts as a growth or maintenance medium for microorganisms in the large bowel or other regions of the gastrointestinal tract, and an oligosaccharide. Method of increasing the number of probiotic or resident microorganisms in the gastrointestinal tract of an animal comprising providing to the animal the probiotic composition.

Abstract: The application discloses a method for the treatment of Heliobacter infection in a mammalian host, which comprises administration to said infected host of an immunologically effective amount of one or more Heliobacter antigen(s), optionally in association with a mucosal adjuvant.

Abstract: A probiotic composition is disclosed which is particularly useful for inclusion in food products to enhance their nutritional value. The composition comprises one or more probiotic microorganisms such as Bifidobacterium and a carrier to transport the microorganisms to the large bowel or other regions of the gastrointestinal tract. The carrier is a modified or unmodified resistant starch, particularly a high amylose starch, which acts as a growth or maintenance medium for microorganisms in the large bowel or other regions of the gastrointestinal tact.
