  • Patent number: 9243078
    Abstract: A method to increase the molecular weight of wood mannans and xylans comprising aromatic moieties comprises the steps: a) obtaining mannan and/or xylan from wood, b) subjecting the mannan/xylan to oxidizing conditions to convert at least a fraction of the aromatic groups into radicals and reacting said radicals with each other to obtain complexes of mannan/xylan with increased molecular weight. The method is easy and cost efficient and enables to upgrade small wood mannans and xylans that are important in the pulp and paper industry into larger mannans and xylans and more defined structures which makes their isolation easier and application areas broader. Another advantage is that separation of mannans and xylans from mannans and xylans with bound aromatic groups is provided. The wood mannans and xylans with increased molecular weight can be used for the manufacture of barrier films in packages, for instance for oxygen, liquids and gas.

    Abstract: The invention provides a process for preparing a conjugate of a S. aureus type 5 or type 8 capsular polysaccharide and a carrier molecule, comprising the steps of: (a) depolymerizing the capsular polysaccharide, to give a polysaccharide fragment; (b) oxidizing the fragment in order to introduce an aldehyde group into at least one saccharide residue in the fragment, to give an oxidized saccharide residue; and (c) coupling the oxidized saccharide residue to a carrier molecule via the aldehyde group, thereby giving the conjugate. The coupling in step (c) may be direct, or may be via a linker molecule. The invention also provides a conjugate obtained or obtainable by this process.

  • Patent number: 8975387
    Abstract: Compositions of matter are provided that include chitosan and a modified carbohydrate. The modified carbohydrate includes a carbohydrate component and a cross linking agent. The modified carbohydrate has increased carboxyl content as compared to an unmodified counterpart carbohydrate. A carboxyl group of the modified carbohydrate is covalently bonded with an amino group of chitosan. The compositions of matter provided herein may include cross linked starch citrate-chitosan and cross linked hemicellulose citrate-chitosan, including foams thereof. These compositions yield excellent absorbency and metal chelation properties. Methods of making cross linked modified carbohydrate-chitosan compounds are also provided.

  • Publication number: 20150064331
    Abstract: A method and a system for preparing xylan and calcium carbonate, xylan, a cellulose fibre, and precipitated calcium carbonate. The method includes extracting xylan from cellulose fibres with sodium hydroxide to form a mixture containing cellulose fibres and an extract solution containing xylan; removing the cellulose fibres from the mixture to isolate the extract solution; adding carbon dioxide to the isolated extract solution to form a mixture containing a liquid brightener and precipitated xylan; separating the brightener from the mixture to isolate the precipitated xylan; adding calcium hydroxide to the separated brightener to form a mixture of precipitated calcium carbonate and liquid sodium hydroxide; and removing the sodium hydroxide from the mixture to isolate the calcium carbonate.

  • Patent number: 8962824
    Abstract: Aspects of the invention provide compositions for use in the treatment galectin-dependent diseases. In particular, compositions comprising a selectively depolymerized, branched galactoarabino-rhamnogalacturonate whose backbone is predominantly comprised of 1,4-linked galacturonic acid (GalA) moieties, with a lesser backbone composition of alternating 1,4-linked GalA and 1,2-linked rhamnose (Rha), which in-turn is linked to any number of side chains, including predominantly 1,4-b-D-galactose (Gal) and 1,5-a-L-arabinose (Ara) residues.

  • Publication number: 20150044301
    Abstract: A system is disclosed for preparing a hypodermic injection site comprising a visibility enhancer for an injection site and a post injection hypodermic puncture wound site. The present invention offers a number of significant improvements which advance the efficacy of the art, by: preventing unintentional hypodermic injection of medicines through un-sanitized or under-sanitized skin surfaces, thereby protecting patients from becoming inoculated with pathogenic microorganisms while receiving such injections; significantly improving the visibility of, and, the accurate visual location and bandaging of post-injection needle puncture entry wounds, thereby further reducing the risk of infection of such wounds; and, by reducing bleeding from such wounds, which, in turn, reduces healthcare worker exposure to blood-borne pathogens and reduces the generation of potentially infectious, biohazardous medical waste.

  • Publication number: 20150038685
    Abstract: An immunogenic composition having 13 distinct polysaccharide-protein conjugates and optionally, an aluminum-based adjuvant, is described. Each conjugate contains a capsular polysaccharide prepared from a different serotype of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) conjugated to a carrier protein. The immunogenic composition, formulated as a vaccine, increases coverage against pneumococcal disease in infants and young children globally, and provides coverage for serotypes 6A and 19A that is not dependent on the limitations of serogroup cross-protection. Also described is a method for making an immunogenic conjugate comprising Streptococcus pneumoniae serotype 1 polysaccharide covalently linked to a carrier protein, the method including partial de-O-acetylation of the polysaccharide by mild hydrolysis in an alkaline pH buffer.
