Abstract: [Problem] To provide: a lipid membrane structure which has such a particle diameter that the lipid membrane structure can be sterilized by filtration, contains a lipid that is bound to a peptide composed of multiple arginine residues as a constituent lipid, and includes a bacterial cell component having dispersibility in a non-polar solvent; and a method for producing a lipid membrane structure which has such a particle diameter that the lipid membrane structure can be sterilized by filtration and includes a substance of interest having dispersibility in a non-polar solvent. [Solution] A lipid membrane structure which has such a particle diameter that the lipid membrane structure can be sterilized by filtration, contains a lipid that is bound to a peptide composed of multiple arginine residues as a constituent lipid, and includes a bacterial cell component having dispersibility in a non-polar solvent.

Abstract: An object of the invention is to provide a medical drug, a food and drink having a role in regulating the concentration of equol in vivo and being capable of taking for a long time with high safety and provide a selective medium for a microorganism having conversion ability to equol and a method of detecting the same. Provided are an equol concentration-raising or reducing agent containing a carbohydrate as an active ingredient; use of a carbohydrate for producing the equol concentration-raising or reducing agent; a method of raising or reducing the concentration of equol by administrating a carbohydrate in an effective dose; a selective medium containing a carbohydrate for a microorganism having conversion ability to equol; and a method of detecting a microorganism having conversion ability to equol by use of the selective medium.

Abstract: The present invention developed a novel antitumor agent for renal cell carcinoma that cannot be fully treated by the existing therapies. The present invention provides an antitumor agent comprising a combination drug of tegafur/gimeracil/oteracil potassium that ensures an excellent therapeutic effect in renal cell carcinoma patients that is superior to that of the existing therapies, by way of selecting the patients based on thymidylate synthase.

Abstract: The present invention is directed to a microorganism having an ability of converting daidzein to equol in 24 hours of 50% or higher; a food/beverage or pharmaceutical composition containing the microorganism; an equol production method employing the microorganism; and a nucleic acid fragment which can specifically detect the microorganism.

Abstract: The object is to provide a liposome by which a bacterial cell component insoluble in water and an organic solvent (e.g., BCG-CW) can be pharmaceutically prepared in a form applicable to a living body (i.e., a form in which the bacterial cell component can be dispersed in an aqueous solvent and has a controlled size) without using any surfactant. Disclosed is a liposome having a lipid membrane containing a bacterial cell component insoluble in water and an organic solvent (e.g., BCG-CW).
