摘要:
Disclosed herein is an apparatus and method for detecting the motion characteristics of particles in a flow channel. The apparatus of the present invention includes first and second electrode groups, each comprising a pair of electrodes, which are arranged to be spaced apart from each other in a flow channel, the pair of electrodes functioning as both a drive electrode and a sensing electrode for directly applying voltage and measuring impedance between the electrodes. An operation control unit measures variation in electrical pulses generated in the first and second electrode groups, thus detecting motion characteristics of the particles. The present invention is advantageous in that it does not require complicated optical measuring instruments or analyzing instruments, and in that it can be used to easily detect the motion characteristics of particles in a flow channel merely by analyzing variation in electrical pulses without requiring preliminary information.

According to a device and system for measuring the properties of cells, there is an advantage in that, since a cell accommodation unit having a volume is provided, the properties of three-dimensional cells can be measured. Further, the present invention is advantageous in that it enables passive measurement of multiple properties which passively measures the electrical, mechanical and/or optical properties of cells, and active measurement of multiple properties which actively applies electrical, mechanical and optical types of stimulation to cells and measures their electrical, mechanical and/or optical reactions, thus measuring the multiple properties of cells with high reliability.

Disclosed herein is a droplet receiver. The droplet receiver includes an internal space formed such that its sectional area is reduced towards an input part, thus preventing the rebounding of droplets which enter a droplet receiving part, and includes an intercepting fluid layer so as to isolate the received droplets from the outside, thus preventing droplets received in the droplet receiving part from being contaminated and volatilizing.

Infrared sensor that can make a temperature compensation by itself, and method for compensating a temperature thereof, are disclosed. The infrared sensor preferably includes a substrate, a diaphragm formed on the substrate, and a first thermopile sensor formed on a region of the diaphragm for sensing an infrared radiation emitted from a measured object and infrared radiations emitted from regions other than the measured object. A second thermopile sensor is formed on a region of the diaphragm and connected to the first thermopile sensor for sensing the infrared radiations emitted from the regions other than the measured object. A housing protects a front face of the substrate including the first, and second thermopile sensors includes an infrared filter in the housing over the first and second thermopile sensors for transmission of infrared radiations, and a reflector reflects the infrared radiation emitted from the measured object toward the first thermopile sensor. The method for temperature compensation can include the steps of letting an infrared radiation from a measured object be directed to the first thermopile sensor and letting infrared radiations from regions other than the measured object be directed to the first and second thermopile sensors, respectively, sensing the infrared radiations in the first and second thermopile sensors directed thereto, and making a temperature compensation for the infrared radiations from regions other than the measured object using the first and second thermopile sensors to provide a temperature component of the measured object only.

Disclosed is a novel use of phytosphingosine. More particularly, disclosed are a composition for preventing or treating hyper-proliferative skin diseases comprising pachastrissamine as an active ingredient, a use of pachastrissamine or a pharmaceutically acceptable salt thereof for preparing a preventing/therapeutic agent of hyper-proliferative skin diseases, and a method for treating hyper-proliferative skin diseases administering an effective amount of pachastrissamine or a pharmaceutically acceptable salt thereof to a subject in need thereof. The pachastrissamine inhibits the degradation of FoxO3a protein and increases the expression of FoxO3a protein. Thus, the inventive pharmaceutical composition has a preventing of treating effect on hyper-proliferative diseases by inducing apoptosis of hyper-proliferative cells and inhibiting the cell cycle. Accordingly, the disclosed composition, a use, and the method can be used for preventing or treating various hyper-proliferative skin diseases such as skin cancer or psoriasis.

摘要:
The present invention relates to compositions for preventing or treating angiogenesis-mediated diseases or allergic diseases which contain, as an active ingredient, an EC-SOD protein or a vector having a polynucleotide encoding thereof. The EC-SOD protein or the vector having a polynucleotide encoding the EC-SOD protein has the effect on inhibiting angiogenesis by inhibiting the expression of VEGF and MMP-9 which induce angiogenesis. Therefore, the EC-SOD protein or the vector may be useful for preventing or treating angiogenesis-mediated diseases. And the EC-SOD protein or the vector having a polynucleotide encoding said EC-SOD protein also has the effect on inhibiting over-differentiation of Th2 cells which cause allergic diseases, inhibiting transcription factor (NF-κ B), and reducing degranulation of human mast cells. Accordingly, the EC-SOD protein or the vector may be useful for preventing or treating allergy diseases. In addition, the inventive method for preparing an EC-SOD protein may be used in preparing an EC-SOD protein having the activity on a large scale. Therefore, the inventive method may be useful industrially.
