Abstract: The present invention relates to the novel use (anti-inflammatory activity) of Ramalin isolated from the Antarctic lichen Ramalina terebrata, and more specifically to a pharmaceutical composition containing Ramalin as an active ingredient. Ramalin of the invention is a compound derived from natural material, has no toxicity or side effects, and inhibits the expression of inducible nitric oxide synthase (iNOS) in the transcription stage to significantly inhibit the production of nitric oxide (NO) that is a key mediator of inflammatory responses. In addition, it inhibits the activation of the inflammatory mediator NF-?B, inhibits p38 MAPK, ERK1/2 and JNK signaling pathways, and inhibits the expression of the LPS receptor TLR4, suggesting that Ramalin has an excellent anti-inflammatory effect. Thus, the composition containing Ramalin can be effectively used to fundamentally treat or prevent inflammatory diseases or immune diseases and to relieve or alleviate the symptoms of the diseases.

Abstract: The present invention relates to a novel compound having excellent antioxidant activity, isolated from Ramalina terebrata, and more particularly to a novel compound, RAMALIN™, having excellent antioxidant activity, isolated from the Antarctic lichen Ramalina terebrata, a method for preparing the RAMALIN™, and a pharmaceutical composition, a functional food and a functional cosmetic composition, which contain the RAMALIN™ as an active ingredient. The RAMALIN™ according to the invention has significantly excellent antioxidant effects compared to commercially available antioxidants, and thus can be widely used in agents for treating oxidation-related diseases, anti-aging functional foods, functional cosmetic products for skin whitening and wrinkle reduction, etc.

The rotor includes a plurality of rotor cores radially disposed and a plurality of magnets respectively disposed between rotor cores. The area of a lateral surface of each of the magnets adjoining a lateral surface of a corresponding one of the rotor cores is greater than the area of an imaginary plane connecting one end of an upper end portion of each of the magnets to one end of a lower end portion of each of the magnets.

Abstract: The present invention relates to a method for synthesizing ramalin, and more particularly to a method for synthesizing ramalin, which comprises allowing 2-hydrazinylphenol to react with L-glutamic acid having a protected carboxyl group at C-1 and a protected amino group at C-2, and a method for preventing decomposition of the ramalin. According to the present invention, ramalin having excellent antioxidant and anti-inflammatory activities can be synthesized in high yield, and thus can be produced in large amounts. In addition, ramalin can be stably maintained for a long period of time, and thus can be easily used for industrial purposes.

Abstract: The driving apparatus of a display device calculates a slope using a minimum gray, a maximum gray, a gray average of frame data in a current frame, and a gray average of frame data in a previous frame, and corrects and outputs the input frame data according to the slope, using frame data of one frame. As a result, a gray range of the input image signal can be extended, thereby improving visibility. Further, in a case of a motion picture, even when a difference of a gray range of images of adjacent frames is large, an original image is not distorted due to extension of a gray range. Also, even when noise is included in the input image signal, a gray range can be extended after removing the noise.
