20090099302 | Aqueous Dispersion of Hybrid Particles Consisting of Organic or Inorganic Pigment Particles and Organic Nano-Particles and Process for Preparing the Same - An aqueous dispersion of hybrid particles consisting of inorganic or organic pigment particles and organic nano-particles attached to the surface of the pigment particles, the nano-particles having a particle size between 2 and 200 nanometers. Preferably the nano-particles have a glass transition temperature of at least 120° C. and comprise co-polymers of vinyl monomers and a mixture comprising maleic anhydride and derivates of maleic anhydride. In a process for preparing such an aqueous dispersion a copolymer of vinyl monomers and maleic anhydride is treated in water with a compound having the general formula R—NH | 04-16-2009 |
20090253828 | PARTICLE IN THE SHAPE OF AN ENCAPSULATED DROPLET AND PROCESS FOR MAKING SUCH A PARTICLE - Particle in the shape of an encapsulated droplet comprising a core material and a shell material surrounding the core material, the shell material containing maleimide groups, preferably a copolymer of maleimide groups. The shell material contains a copolymer of styrene and maleic anhydride derivatives, of which more than 75 mole %, preferably more than 90 mole % is maleimide, and the average particle size is smaller than 300 nm. The particles are obtained by a process comprising by heating between 80° C. and 195° C., more preferably between 120° C. and 190° C. an ammonium salt of a maleic anhydride containing polymer in the presence of the core material. | 10-08-2009 |

20120058551 | TECHNOLOGY AND METHOD TO STUDY MICROBIAL GROWTH AND ADHESION TO HOST-RELATED SURFACES AND THE HOST-MICROBIOTA INTERACTIONS - The present invention relates to in vitro adhesion modules that allow growth, stabilization and study of microbial communities that adhere to and colonize host-related surfaces, that mimic transport of chemical compounds across epithelial surfaces and simulate host-microorganism interactions and adaptation. It includes the provision of micromolar amounts of oxygen via the basal side of a mucus layer towards the adhered microorganisms thus establishing the microaerophilic conditions prevailing at the base of a biofilm. It can also include cells, simulating the host, in a chamber on the basal side of a functional layer comprising said mucus layer. The adhesion module of the present invention can be placed between the different compartments of the SHIME—the Simulator of the Human Intestinal Microbial Ecosystem. An extension of the SHIME is made where the duodenum, jejunum and ileum are separately mimicked. | 03-08-2012 |
20130203161 | TECHNOLOGY AND METHOD TO STUDY MICROBIAL GROWTH AND ADHESION TO HOST-RELATED SURFACES AND THE HOST-MICROBIOTA INTERACTION - A method is provided for co-culturing viable cells and microorganisms for at least 48 hours in which an adhesion module is provided including a basal compartment and a luminal compartment separated by a semi-permeable membrane, and a continuous or semi-continuous flow of fresh medium is applied to the basal compartment. | 08-08-2013 |

20120230955 | ARABINOXYLANS FOR MODULATING THE BARRIER FUNCTION OF THE INTESTINAL SURFACE - The present invention is directed to a particular arabinoxylan (“AX”) preparation and the finding that this preparation has a beneficial effect on the organization of the intestinal microbial community in the lumen and in particular at the site of the gut mucosa, where it modulates the barrier function of the intestinal surface, primarily by modulating the mucosa-associated microbial community towards a relative increase of health beneficial bacteria, such as bifidobacteria and lactobacilli. It is accordingly a first aspect of the present invention to provide said arabinoxylan preparation characterized in comprising isolated water-soluble arabinoxylans and the use thereof to improve functioning (e.g. barrier function) of the intestinal epithelium. Thus, in a further aspect the present invention provides compositions, both pharmaceutical and nutritional compositions, comprising said arabinoxylan preparations; in particular pharmaceuticals, medical foods, food supplements or food compositions, such as infant formula products, dairy products, bakery products or pastry products. The compositions optionally comprise probiotics such as | 09-13-2012 |
