Abstract: The present invention relates to a composition comprising centipede grass extract as an active ingredient for the prevention or treatment of alopecia. Particularly, the centipede grass extract of the present invention increases the expression of hair growth related factors and accelerates hair growth, so that it can be effectively used for the prevention or treatment of alopecia.

Abstract: The present invention relates to a composition for controlling plant diseases containing a limonene derivative as an active ingredient. In the present invention, the limonene derivatives have an effect of inhibiting the growth of Xanthomonas oryzae pv. Oryzae (Xoo), which is a pathogen mediating bacterial leaf blight, and Magnaporthe oryzae, which is a pathogen mediating rice blast, and it was confirmed in an experiment with respect to inhibition using volatility (i.e., in a state not being in direct contact with Xoo or M. oryzae) that the limonene derivatives have a growth inhibitory effect. Accordingly, the limonene derivatives have an inhibitory effect against the growth of Xoo and thus they can be effectively used as a composition for controlling plant diseases.

Abstract: An AhpF protein has thioredoxin reductase, peroxidase, and chaperone activities and is derived from Pseudomonas aeruginosa, and a use therefor. By using a novel activity of the AhpF of Pseudomonas aeruginosa according to the present invention, it is possible to produce a plant having strong resistance to various environmental stresses such as oxidative stress or heat stress, thereby making it possible to contribute to increasing crop productivity and mass production of useful constituents. In addition, it is possible to prevent desertification and environmental pollution through the development of transformed plants having resistance to high temperatures and drying.

Abstract: The present invention relates to a pharmaceutical composition for preventing or treating diabetes or dementia, comprising centipede grass (Eremochloa ophiuroides) extracts as an active ingredient. It has been identified from animal tests that the centipede grass extracts, fractions thereof, and active fractions separated from the said fractions effectively regulate blood glucose levels, and inhibit the activity of amyloid-?(A?) which is involved in the formation of amyloid plaques that might cause dementia. Thus, the extracts, the fractions thereof, and the active fractions separated from the said fractions can be effectively used in a composition for preventing and treating diabetes or dementia, in a functional food for preventing or improving diabetes or dementia, and in a pharmaceutical composition or health food for blood glucose regulation.

Abstract: The present invention relates to rotenone derivatives and a use of the same. Particularly, the present inventors identified rotenoisin A and B which are compounds with no toxicity and which are prepared by irradiation with gamma rays onto rotenone as represented by the following formula 1. It was further confirmed that the rotenone derivatives significantly inhibited pancreatic lipase activity and preadipocyte differentiation. The rotenone derivatives of the present invention can be effectively used as a composition for the prevention and treatment of obesity and as a composition for health functional food for the prevention and improvement of obesity: (In formula 1, R1 and R2 are as defined in this description).

Abstract: The present invention relates to a method for increasing chaperone activity by irradiating peroxiredoxin (Prx) proteins. More particularly, the present invention may be useful for preparing recombinant proteins imparting resistance against various environmental stresses by increasing the chaperone activity of peroxiredoxin, since it has been observed that irradiated peroxiredoxin has enhanced chaperone activity characteristics, wherein an ?-helix structure decreases while a ?-sheet structure increases, from analysis results of a protein structure change and chaperone activity after irradiating two types of peroxiredoxins (2-Cys, 3-Cys) which are two active cysteine motifs of peroxiredoxin.
