Abstract: Provided is a method of isolating a botulinum toxin type A macro complex from a botulinum toxin-containing solution, the method including performing anion exchange chromatography and cation exchange chromatography.

Abstract: Compositions for removing silicone resins and methods of thinning a substrate by using the same, as well as related methods, apparatus and systems for facilitating the removal of silicone resins are provided. The compositions for removing silicone resins, may include a heterocyclic solvent and an alkyl ammonium fluoride salt represented by a formula, (R)4N+F?, wherein R is a C1 to C4 linear alkyl group. Silicone resins may be effectively removed by using the compositions since the compositions exhibit an excellent decomposition rate with respect to the silicone resins that remain on a semiconductor substrate in a process of backside grinding of the semiconductor substrate, backside electrode formation, or the like.

Abstract: Disclosed are a method for dispersing plant sterol for beverage and a plant sterol-dispersed beverage, of which particle size is nanometer-scale in dispersed beverage. The dispersion of plant sterols starts with the admixing of plant sterol to at least one emulsifier selected from the group consisting of sucrose fatty acid ester, sorbitan fatty acid ester and polyglycerine fatty acid ester, followed by melting the admixture by heating at 60 to 200° C. Afterwards, the molten substance is mixed with an aqueous beverage alone or an emulsifier-containing aqueous beverage in state of its own molten type or power type. This resulting mixture is stirred at a high speed to give a dispersion of plant sterols in an aqueous beverage. The beverage is superior in bioavailability, having good mouth feel, transparent aspect and no influence on the characteristic taste, flavor and color of the beverages.

Abstract: Disclosed are a method for dispersing plant sterol in aqueous substrates and a plant sterol-dispersed beverage. The dispersion of plant sterols starts with the admixing of plant sterol to an emulsifier, followed by melting the admixture by heating at 60 to 200° C. Afterwards, the molten substance is mixed with an aqueous beverage alone or an emulsifier-containing aqueous beverage. This resulting mixture is stirred at a high speed to give a dispersion of plant sterols in an aqueous beverage. Optionally, the dispersion may be homogenized. In the beverage thus obtained, there are contained nano-sized micelles which are superior in bioavailability, having no influence on the characteristic taste and flavor of the beverages. Also, the improvement in the dispersion stability of the plant sterol micelles has the effect of prolonging the life span of the beverage, guaranteeing the stability of the products for a long period of time.
