Abstract: The present invention discloses a sensor chip for screening a topoisomerase inhibitor and a screening method thereof. The sensor chip comprises topoisomerase I and a biochip. The topoisomerase I is immobilized on the biochip, and the topoisomerase I has DNA catalytic activity. This provides a rapid screening method for topoisomerase I inhibitors.

Abstract: The present invention discloses a grain germinating system comprising a temperature controlling device, an incubation device, a drying device and a monitoring device. The temperature controlling device comprises a heat pump module, an air conditioning module and a piping module. The heat pump module can output a high or low temperature heat exchanging liquid. The temperature of a culture medium of a grain is adjusted by the incubation device. The incubated grain is dried by the drying device. The air conditioning module is for a plant building. The piping module is connected with the heat pump module, and is provided for the high or low temperature heat exchanging liquid to flow. The incubation device and the drying device are heated by the high temperature heat exchanging liquid. The drying device is cooled by the low temperature heat exchanging liquid provided for the air condition of the plant building to use.

Abstract: The invention relates to the compounds isolated from Evodia rutaecarpa (Juss.), in that has been demonstrated to inhibit topoisomerase I. Evodiamine, an alkaloidal compound is reported the topoisomerase I inhibitory activity. The effect of evodiamine acts by stabilizing the covalent complex between topoisomerase I and DNA, which results in a blockade of DNA replication and transcription.

Abstract: A skin whitening composition and a method for the same are provided. The skin whitening composition comprises a far-infrared ray releasing substance having a primary component of an oxide mineral, wherein the skin whitening composition achieves a whitening effect via an irradiation of the far-infrared ray releasing substance. In another aspect, the method comprises the steps of administering a far-infrared ray releasing substance to a subject and reducing melanogenesis of the subject by inhibiting growth of a pigment cell, wherein the far-infrared releasing substance has an oxide mineral.
