摘要:
The invention relates to novel enzymes, which transfer sialic acid from a donor molecule onto an acceptor molecule (trans-sialidases). The enzymes are isolated from the protozoan Trypanosoma congolense. The invention also relates to functional equivalents of said enzymes, to the nucleic acid sequences and amino acid sequences that code for the enzymes and their functional equivalents, to expression constructs and vectors that contain said sequences, to recombinant microorganisms that carry the inventive coding nucleic-acid sequences, to a method for the recombinant production of the inventive enzymes, to a method for isolating said enzyme from Trypanosoma congolense, to a method for the enzymatic sialization of acceptor molecules using the inventive enzymes, to effectors of the inventive trans-sialidases, to the use of the nucleic acid sequences, amino acid sequences, enzymes, effectors or sialization products for producing vaccines, medicaments, foodstuffs or food additives, in addition to the latter products obtained by the inventive method.

The present invention provides the use of a composition comprising non-digestible oligosaccharide for the manufacture of a composition for enteral administration to an infant delivered via caesarean section.
摘要:
The present invention relates to compositions to be administered to infants delivered via caesarean section and in particular to a product comprising inactivated cells and/or bacterial cell fragments of Gram-negative bacteria and of optionally inactivated Gram-positive bacteria. Thereby it is possible to stimulate a fast colonisation of the intestinal microbiota of said infants.
摘要:
The invention relates to the use of a peptide mixture comprising peptides with a molecular weight from 1000 to 5000 Daltons for the prevention and/or treatment of tumour diseases, of diseases which are associated with a development disorder of the immune system, of diseases of the immune system, of autoimmune reactions, of allergies and of inflammation in man, a protein component which contains such a peptide mixture and a formula food containing this peptide mixture. The peptides are preferably obtained from non-human proteins suitable for nutritional purposes, in particular by the enzymatic or hydrolytic cleavage of these proteins.
摘要:
Neutral straight-chain or branched oligosaccharides for preventing the invasion and infection of mammal cells by pathogens and for fighting diseases caused by such pathogens are disclosed. Food, dietetic products and pharmaceutical agents containing oligosaccharides consist of a base unit of formula (I), and between 0 and 19 other units of formula (II), which are linked directly or indirectly to the base unit. Gal represents a galactose monosaccharide unit; Glc represents a glucose monosaccharide unit; HexNAc rpresents an N-acetylated galactosamine or glucosamine monosaccharide unit (GalNAc or GlcNAc); R independently represent a β 1-3 or β 1-6 glycosidic link to HexNAc monosaccharide of the next [Gal-HexNAc] unit (II), and on a terminal [Gal-HexNAc] unit, or R are not present; and a terminal [Gal-HexNAc] unit, wherein R represent a deoxyhexose radical, can have another deoxyhexose radical on the HexNAc monosaccharide unit.

The present invention provides the use of a composition comprising uronic acid oligosaccharide for the manufacture of a composition for enteral administration to an infant delivered via caesarean section.
摘要:
The invention relates to the use of sialic carbohydrates of general formula (I), containing at least one carbohydrate unit of general formula (II) for the immune modulation, immune suppression and in the prevention and treatment of infections in humans and animals. In said formula (II), Sia represents a sialic acid or a sialic acid derivative in an α2-3 bond, Gal represents a galactose-monosaccharide-unit, HexNac represents an N-acetylated galactosamine or glucosamine-monosaccharide-unit (GalNAc or GlcNAc), Hex represents a galactose- or glucose-monosaccharide-unit (Gal or Glc), C represents HexNac or Hex or is absent, n represents 1-50, V represents OH, a carbohydrate radical or a connecting point on a support T, with the proviso that if V represents OH, n represents 1, and if V represents a carbohydrate radical or a support T, n represents the number of carbohydrate unites of general formula (II) directly connected to said carbohydrate radical or support, X represents a sialic acid or a sialic acid derivative, wherein a second sialic acid or a sialic acid derivative or more sialic acid or sialic acid derivatives can be connected to an α2-8 bond, a phosphate, a sulphate, or carboxyl-group or a monosaccharide having a phosphate, sulphate, or carboxyl group and only one of the radicals X is present.

The present invention relates to methods for feeding of infants delivered via caesarean section and to compositions to be administered to infants delivered via caesarean section and in particular to the use of a product obtained by fermentation of milk, whey, whey protein, whey protein hydrolysate, casein, casein hydrolysate and/or lactose by lactic acid producing bacteria. Thereby it is possible to stimulate a fast colonisation of the intestinal microbiota of said infants.
