Abstract:
The present invention provides a method for identifying modulators that modulate physiological functions of intracellular components within a cell. The method for identifying modulators that modulate physiological functions of intracellular components according to the invention, comprises: imaging a pattern of a magnetic substance that is magnetized in the direction of the magnetic flux as well as a pattern of a tracer that is coupled with the cellular component; and then determining whether there is a competing reaction between a reference substance and a modifier in the cell. One advantage of the present invention is that since the reaction in a cellular component for the modifier such as a drug and the reference substance occurs in a living cell, the competing reaction between the modifier and the reference substance represents actual intracellular metabolism. Also, the present invention is advantageous in that a plurality of modifiers can be screened using a small number of reference substances, and that the function of a modifier in cells, i.e., pharmaceutical efficacy, can be searched without changing the modifier with introduction of a reference substance.

The present invention provides a method for exposing particles to cytoplasm, comprising the steps of delivering particles into live cells, enabling a cytoplasm exposure additive to contact the cells for exposing the particles to cytoplasm from endocytic vesicles when the physiological, biochemical, or biological environments of the cells are kept intact, and enabling the particles to be exposed to the cytoplasm from the endocytic vesicles. The present invention is advantageous in that particles delivered into cells can be effectively exposed to cytoplasm from endocytic vesicles in intact cells when the physiological, biochemical, or biological environments of the cells are kept intact.

The present invention relates to a high strength mega-truss structure, which is adapted to be effective to the vibration by constructing steel-concrete sandwich beams with the advantage of construction efficiency of a steel structure and the advantage of high strength and high damping capacity of an RC structure by means of the synthetic action of steel member and concrete, as upper and lower floor beams, and disposing web members between the upper and lower floor portions to thereby make the upper and lower floor beams move concurrently, and a factory building accomplished as an anti-vibration building by applying such mega-truss structure to it. The high strength mega-truss structure of the present invention, comprises an upper floor beam constructed by a steel-concrete sandwich beam; a lower floor beam constructed by a steel- concrete sandwich beam; a primary web member disposed to define a wave shape between the upper floor beam and the lower floor beam; and a secondary web member disposed to define a wave shape between the upper floor beam and the lower floor beam and disposed to be spaced apart from the primary web member, wherein the filled concrete of the upper floor beam is constructed integrally with slab concrete above the upper floor beam, and the filled concrete of the lower floor beam is constructed integrally with slab concrete above the lower floor beam.
Abstract:
Disclosed is an energy-saving and environmentally-friendly filtering system which minimizes energy consumption during a filtering process so as to dramatically reduce water treatment costs. According to the present invention, an inter-membrane pressure difference higher than a threshold membrane pressure is naturally generated by a head pressure of raw water and/or by water pressure of filtered water based on the siphon principle, and thus the amount of energy consumed during the filtering process is minimized.

The present invention provides a method for patterning magnetic materials in live cells, comprising the steps of preparing a plurality of nanoencapsulated and surface-modified magnetic materials which are magnetized in a magnetic line of force by a magnetic field, providing the magnetic materials into live cells in such a manner that the plurality of magnetic materials can be provided to one live cell, applying a focused magnetic field onto the live cells to enable bundles of magnetic lines of force to pass through the live cells in a predetermined direction, enabling the plurality of magnetic materials to be arranged in the magnetic line of force of the magnetic field in the live cells, and checking the pattern of the arrangement of the magnetic materials.
Abstract:
A location information tagging method and system for location-based services in a wireless communication system are provided. In the method, if it is determined that a service request message received from a device is being sent to an application server for providing a service based on a location of the device, location information about a base station is tagged to the service request message. The service request message with the tagged location information is transmitted to the application server. Therefore, the application server can obtain location information about the device by merely depending on the message received from the device without referring to a conventional location service server. This reduces a service response time and also rapidly offers a location-based service.
Abstract:
The present invention provides a peptide for delivering cargoes into cells, wherein the peptide contains an intracellular transduction domain. Said intracellular transduction domain is a peptide containing a hydrophilic domain for improving the interaction between charged materials and/or the solubility of the intracellular transduction domain and the cargoes, and a hydrophobic domain which can be used in a hydrophobic interaction and/or an interaction with cell membranes. Said intracellular transduction domain delivers the cargoes into cells when the intracellular transduction domain is not conjugated to the cargoes. The present invention provides a method for delivering cargoes into cells that comprises the steps of preparing an intracellular transduction domain, preparing cargoes to be delivered into cells, treating cells with the cargoes and the intracellular transduction domain when the cargoes and the intracellular transduction domains are not conjugated to each other, and delivering the cargoes into cells.
Abstract:
Disclosed herein is a hemodialysis tube treated with a medicament on the surface thereof, which provides stable communication between the artery and the vein of the patient under hemodialysis and can greatly reduce stenosis at arteriovenous connections. As a base material of the hemodialysis tube, expanded polytetrafluoroethylene is used while the medicament is paclitaxel or rapamycin.

A lighting apparatus for broadcasting can comprise an ionic wind generator further comprising: a plate-shaped lighting portion, on an upper surface of which a plurality of light sources are arranged; a heat dissipation portion, which is coupled to a lower surface of the lighting portion, for dissipating heat from the lighting portion to the exterior; and first and second electrodes, which are in contact with the lighting portion and the heat dissipation portion and are arranged so as to be separated away from each other; and an ionic wind generator for generating the ionic wind from between the first and second electrodes by means of a potential difference of a voltage which is applied to the first and second electrodes, and for transferring the heat from the lighting portion and the heat dissipation portion to the exterior by using the ionic wind.
Abstract:
Disclosed herein are a tube for arteriovenous anastomosis useful in hemodialysis patients and an insert for use in medicinal operation in the body. The tube or the insert are repetitively treated with a medicament on the surface thereof, which provides stable communication between an artery and a vein of a patient under hemodialysis and can greatly reduce stenosis at arteriovenous connections by releasing the medicament at a suitable rate over a prolonged period of time.
