Abstract: An object of the present invention is to provide a novel composition that is, for example, effective in suppression of deterioration of mental function. The present invention provides a composition for use in suppressing deterioration of mental function, comprising a hop oxidation-reaction product. Conditions of deterioration of mental function include conditions selected from the group consisting of depression-related conditions and anxiety-related conditions. The composition of the present invention can be provided in the form of a food composition, and be ingested by subjects with deterioration of mental function or with a risk of deterioration of mental function. The S-fraction can be used as the hop oxidation-reaction product.

Abstract: The present disclosure relates to a composition containing a compound of formula 1 and a compound of formula 2. The present disclosure further relates to compositions containing a compound of formula 1 and a compound of formula 2, and which also contains one or more pharmaceutically acceptable carriers. The compositions may be formulated for oral administration, including as a pill, capsule, or tablet.

Abstract: An object of the present invention is to provide a composition for use in improving, maintaining and/or ameliorating an attention function and/or a judgement function. According to the present invention, there is provided a composition for use in improving, maintaining and/or ameliorating an attention function and/or a judgement function, comprising an enzymatic decomposition product of milk protein as an active ingredient. The enzymatic decomposition product of milk protein is preferably an enzymatic decomposition product of whey protein. The enzymatic decomposition product of milk protein preferably comprises a peptide having an amino acid sequence of GTWY (SEQ ID NO: 1) and a peptide having an amino acid sequence of WY.

Abstract: An oligopeptide having a good anti-inflammation effect on microglia has been found, and based on this finding, a composition to be used for suppressing the inflammation of microglia is provided. Inflammation suppression action of a dipeptide has been comprehensively analyzed using the proinflammatory cytokine production of microglia as an indicator. As a result, it has been revealed that an oligopeptide including the sequence LH, DV or MH has a good inflammation suppression effect. The composition containing any of these oligopeptides can provide a composition having the effect of suppressing the excessive inflammatory action of microglia.

Abstract: An object of the present invention is to provide a composition that is effective in maintenance, enhancement, improvement, etc. of a cognitive function. The present invention provides a composition comprising a hop oxidation-reaction product for maintaining, enhancing, and/or improving a cognitive function. The cognitive functions include memory function and attention or concentration function.

Abstract: Compositions, foods, and medicaments for enhancing memory and learning function and/or cognitive function are provided. Compositions, foods, and medicaments for improving brain function and particularly enhancing memory and learning function and/or cognitive function can be provided by including a peptide including an amino acid sequence set forth in any one of SEQ ID NOs 1 to 16 as an active ingredient.

Abstract: The present invention provides dendritic cells (DCs) having reduced inflammatory activity, a method for producing DCs capable of inducing regulatory T cells and regulatory T cells, and substances useful for such a method, wherein the DCs and regulatory T cells are useful for prevention and treatment of immune diseases. The present invention relates to a cereal plant-derived material fermented with a koji microorganism, which is obtained by fermentation thereof with a koji microorganism, or a processed product thereof. Preferably, the fermented product or a processed product thereof comprises 14-dehydroergosterol. According to the present invention, regulatory DCs and regulatory T cells can be induced and the proliferation of inflammatory T cells can be suppressed using plant-derived materials.
