Melanophilin (MLPH) of the present invention is involved in differentiation into an adipocyte or fat accumulation, and accordingly, obesity can be treated or prevented by inhibiting the MLPH. Further, by measuring an expression level of the MLPH, obesity can be diagnosed and treated, and therapeutic agents for obesity and agents regulating differentiation into adipocytes can be screened.

Pharmaceutical composition for treating or preventing obesity

A mixer and a reactor including the same are provided. According to one aspect of the present invention, the mixer includes a first piping part into which a first fluid flows, an elbow piping part having an inlet connected to the first piping part and an outlet provided at a location rotated by a predetermined angle from the inlet in a flow direction of the first fluid to have a curved flow path, and a second piping part connected to the elbow piping part to have a central axis perpendicular to a central axis of the first piping part so that a second fluid flows in a tangential direction of the elbow piping part when the second fluid flows into the elbow piping part.

Mixer and reactor including the same

The present invention relates to a polymerization reactor. The polymerization reactor according to one aspect of the present invention comprises: a housing including a supply part for supplying a reactant; a tube which is provided inside the housing and extends along the height direction of the housing; a first impeller including a blade which spirally surrounds the tube along the height direction of the housing; a second impeller which is provided inside the housing in order to enable the reactant to flow into the tube; and a partition wall which is provided to surround the second impeller along the circumferential direction.

Polymerization reactor

The present invention relates to a large-sized vinyl chloride seed with an average particle size of 0.65 to 1.5 &#x3bc;m, a vinyl chloride resin with improved low-viscosity properties, and preparation methods thereof. The preparation of the large-sized vinyl chloride seed includes adding a vinyl chloride monomer, an emulsifier, and a polymerization initiator to an aqueous medium; homogenizing the mixed solution using a rotor-stator type homogenizer; and subjecting the resultant monomer droplets to a polymerization reaction.

Large-sized vinyl chloride seed, method of preparing the seed, vinyl chloride resin prepared using the seed, and method of preparing the vinyl chloride resin

Provided are a vinyl chloride-based resin formed by polymerization of vinyl chloride-based small seed particles having an average particle diameter range of 0.15 &#x3bc;m to 0.5 &#x3bc;m prepared by emulsion polymerization and vinyl chloride-based large seed particles having an average particle diameter range of 0.51 &#x3bc;m to 0.8 &#x3bc;m prepared by micro-suspension polymerization, in which a content ratio (weight ratio) of the large seed particles to the small seed particles is in a range of 1 to 2, and a method of preparing the vinyl chloride-based resin. Excellent low viscosity characteristics of the vinyl chloride resin at high and low shear rates may be obtained by controlling the particle size of the small seed prepared by emulsion polymerization.
