Abstract:
The present invention relates to sulfonamide derivatives as a serotonin receptor antagonist and serotonin reuptake inhibitor and a pharmaceutically acceptable salt thereof. The sulfonamide derivatives have serotonin 5-HT 2A and 5-HT 2C receptor antagonizing and serotonin reuptake inhibiting functions, and thus may be efficiently applied to a CNS-related disease such as depression, obesity, psychosis, schizophrenia, suicidal tendency, anxiety, obsessional neurosis, migraine, appetite disorders, sleep disorders, stroke, and withdrawal symptoms caused by drug abuse.
Abstract:
A GABA (gamma-aminobutyric acid) release-inhibiting agent in the cerebellum and a composition for treating pathological symptoms caused by over-release of GABA in the cerebellum, each comprising a Bestrophin 1(Best1) channel inhibitor as an active ingredient; a GABA release-promoting agent in the cerebellum and a composition for treating pathological symptoms caused by the deficit of GABA in the cerebellum, each comprising a Best1 channel activator as an active ingredient; and a method for screening a GABA release-regulating agent in the cerebellum, which uses Best1 channel as target, are provided.
Abstract:
Embodiments of a method for forming a light emitting device are disclosed. This method includes forming a stacked structure including a substrate, a lower semiconductor layer of a first conductivity type, an active layer, and an upper semiconductor layer of a second conductivity type, wherein the stacked structure includes a separation layer formed below the active layer by ion implantation, and performing a thermal process upon the stacked structure to divide the separation layer laterally such that the stacked structure is separated into an upper part and a lower part. The light emitting device may be fabricated with substrate separation by ion implantation to prevent cracking and enable fabrication of a large size light emitting device having high efficiency at low costs.
Abstract:
Disclosed are a novel, elastic, biocompatible, micro-sized, polyimide- based multi-channel microelectrode for recording of electroencephalography (EEG) from a laboratory animal including mouse, and a method for recording of laboratory animal EEG using the microelectrode. The microelectrode may include 2 grounding electrodes and 32 recording electrodes. A connector for signal transmission easily connects the microelectrode to a signal acquiring apparatus. The total weight of the microelectrode, including the connector, does not exceed 150 mg. Laboratory animal EEG, including that of mouse, provides the advantage of monitoring the brain state of a freely moving animal following a genetic or pharmaceutical manipulation. The microelectrode can be implanted without surgery and may be detached from wires while EEG is not recorded from the laboratory animal. The microelectrode can successfully acquire broadband EEG signals from the skull of the laboratory animal and is effective in monitoring spatial and temporal pattern of brain activities of the laboratory animal.
Abstract:
The disclosure relates to a system for controlling devices and information on a network by hand gestures, and more particularly, to a system for controlling devices and information on a network by hand gestures in which a device or a file to be controlled is selected by a user and a display device is pointed so that information and data can be shared and that various devices can be coupled to each other easily and can be controlled easily. The system for controlling devices and information on a network by hand gestures can remarkably improve the interaction between various input and display devices and a user under a ubiquitous computing environment.
Abstract:
A novel use of anion channels, preferably Ca 2+ -activated anion channels (CAACs), in regulating release of neurotransmitters from neurons and/or astrocytes is provided. More specifically, CAAC activity regulators, agents for regulating neurotransmitter release comprising such CAAC activity regulators, and methods of screening agents for regulating neurotransmitter release using CAAC as a target.
Abstract:
The present invention relates to a composition containing Ortilia secunda extract as an active ingredient. Ortilia secunda extract of the present invention extracted by using water, alcohol or a mixture thereof as a solvent inhibits the activity of AP-I (activator protein-1), a MMP-I transcription factor, inhibits type I collagenase, a skin matrix decomposing enzyme, but increases collagen, a major component of skin, so that it can be effectively used as a preparation for skin external application including cosmetics owing to its wrinkle and elasticity improving effects. In addition, Ortilia secunda extract of the present invention has radial scavenging effect, so that it can also be effectively used as an antioxidative agent.
Abstract:
A bearing seal for a gas turbine for reducing axial leakage of a working gas of a turbine and for supporting the vertical loads and shear forces efficiently. The seal is disposed on an inner surface of a bearing housing where a rotating shaft is positioned at the center of the bearing housing. The bearing seal includes an elastic porous foil for adjusting leakage of a working gas through the space between the rotating shaft and the bearing housing, wherein a density ratio of the porous foil increases along gas inflow direction. The porous foil is deformed elastically by a dynamic pressure of the working gas leaked around the rotating shaft during rotation of the rotating shaft for making a gap between the porous foil and the rotating shaft.
Abstract:
An anode active material for a lithium secondary cell comprising a carbon material which is surface-treated with He, N 2 , CO 2 , O 2 , F 2 , NF 3 or a mixture thereof has a good wetting property for both a water-based binder and a non-aqueous electrolyte, and makes a thin and stable SEI to be formed on its surface, thereby improves the energy density, the reversible capacity and the durability of a lithium secondary cell.
Abstract:
There is provided a metal oxide having a continuous nano-fiber network structure as a negative active material for a secondary battery. A method for fabricating such negative active material for a secondary battery comprises spinning a mixed solution of a metal oxide precursor and a polymer onto a collector to form composite fibers mixed with the metal oxide precursor and the polymer, thermally compressing or thermally pressurizing the composite fibers, and thermally treating the thermally compressed or thermally pressurized composite fibers to remove the polymer from the composite fiber.
