| 1 | Predicting the Rainfall-Triggered Landslides in a Forested Mountain Region Using TRIGRS Model显示文摘Landslides are natural disasters which can pose a serious threat to human and property in many areas around the world. The Transient Rainfall Infiltration and Grid-based Regional Slope-stability (TRIGRS) model was used to investigate the rainfall-induced shallow landslides in a forested mountain region, Korea. Various input data for TRIGRS model include time-varying rainfall, topographic characteristics, soil depth, material strength, and hydraulic properties. A series of calculations were conducted in determining the slope stability over the Jangheung region in Korea during the storm occurred on August 6, 1998. The results show that TRIGRS model captured about 64.1% of landslides that were extracted from the IKONOS2 imageries. The model demonstrated how the factor of safety changed with time during a storm considering both the transient and spatial responses of pore water pressure in its slope stability calculation. | Dongyeob KIM Sangjun IM Sang Ho LEE Youngjoo HONG Kyung-Sub CHA | 2010 | Journal of Mountain Science2010，7，1： | 10 |
| 2 | Functional specialization of Nicotiana attenuata phytochromes in leaf development and flowering time显示文摘Phytochromes mainly function in photoautotrophic organisms to adjust growth in response to fluctuating light signals.The different isoforms of plant phytochromes often display both conserved and divergent roles,presumably to fine-tune plant responses to environmental signals and optimize fitness.Here we describe the distinct,yet partially redundant,roles of phytochromes NaPHYA,NaPHYB1 and NaPHYBi in a wild tobacco species,Nicotiana attenuata using RNAi-silenced phytochrome lines.Consistent with results reported from other species,silencing the expression of NaPHYA or NaPHYBi in N.attenuata had mild or no influence on plant development as long as NaPHYBi was functional;whereas silencing the expression of NaPHYBi alone strongly altered flowering time and leaf morphology.The contribution of NaPHYB2 became significant only in the absence of NaPHYB1;plants silenced for both NaPHYBi and NaPHYB2 largely skipped the rosettestage of growth to rapidly produce long,slender stalks that bore flowers early:hallmarks of the shadeavoidance responses.The phenotyping of phytochrome-silenced lines,combined with sequence and transcript accumulation analysis,suggest the independent functional diversification of the phytochromes,and a dominant role of NaPHYBi and NaPHYB2 in N.attenuata's vegetative and reproductive development. | Variluska Fragoso Youngjoo Oh Sang-Gyu Kim Klaus Gase Ian Thomas Baldwin | 2017 | Journal of Integrative Plant Biology2017，59，3： | 4 |

| 4 | Ameliorating effect of Zhizi(Fructus Gardeniae) extract and its glycosides on scopolamine-induced memory impairment显示文摘OBJECTIVE:To study the chemical constituents of Zhizi(Fructus Gardeniae) and their antiamnesic effect in a mouse model of Alzheimer's disease.METHODS:Ameliorating effects of the extracts,fractions and constituents on scopolamine-induced memory impairment in vivo using a passive avoidance task system and their inhibitory activities on acetylcholinesterase(AChE) in vitro were examined.The isolation of components was performed by chromatographic techniques and their structures were identified on the basis of spectral analysis.RESULTS:Activity-guided fractionation of the total extracts resulted in the isolation of two glycosides,geniposide and crocin from the n-butanol fraction and genipin and crocetin from the ethylacetate fraction.Among the fractions tested,n-butanol fraction showed the strongest AChE inhibition(43.4% at a final dose of 0.03 mg/mL) and also exhibited outstanding efficacy(65.9% at a dose of 250 mg/kg) in an experimental model of amnesia.Geniposide showed a 22.8% AChE inhibitory activity and a potent ameliorating effect on scopolamine-induced memory impairment in amnesic mice of 93.4% as compared to the control group.CONCLUSION:Geniposide,a main constituent of gardenia should be considered a candidate for further clinical study for the purpose of developing a cognition activator and its mechanism of action may be mediated,at least in part,by the acetylcholine enhancing cholinergic nervous system. | Youngjoo Nam Dongung Lee | 2013 | Journal of Traditional Chinese Medicine2013，33，2： | 2 |

| 6 | Ameliorating effects of constituents from Cortex Acanthopanacis Radicis on memory impairment in mice induced by scopolamine显示文摘OBJECTIVE:To investigate the effects of active constituents extracted from Cortex Acanthopanacis Radicison improving the impaired memory in mice models.METHODS:The mice models of memory impairment were established using scopolamine.Ameliorating effects of the fractions and constituents on scopolamine-induced memory impairment in vivo were investigated using passive avoidance and Morris water-maze task tests,and their anti-acetylcholinesterase(AChE)and antioxidant activities in vitro examined.The isolation of constituents was performed by chromatographic methods and their structures were identified on the basis of instrumental analysis.RESULTS:Among the fractions tested,ethylacetate fraction exhibited the anti-AChE activity(25.83%±0.23%)properly and excellent 2,2-diphenyl-1-picrylhydrazyl(DPPH)radical and superoxide anion scavenging capacity(87.50%±0.83%and 60.22%±0.43%,respectively).However,the methylene chloride fraction was much more active than the ethylacetate fraction in the passive avoidance task test(167.5%increase of step-through latency time)and Morris water-maze task test(33.3%decrease of es-cape latency time).Four constituents,β-sitosterol,stigmasterol,sesamin,and hyperin were isolated from the methylene chloride fraction,among them,hyperin showed anti-acetylcholinesterase and anti-oxidant activities remarkably.Moreover,hyperin exerted a potent effect(146±38)s on memory improvement in terms of passive avoidance task test compared with the reference compound tacrine(162±43)s at a dose of 2.5 mg/kg.CONCLUSION:Hyperin,a flavonoid glucoside isolated from Cortex Acanthopanacis Radicis,inhibited AChE activity and potently ameliorated scopolamine-induced memory impairment,and its action may be partially mediated by the acetylcholine-enhancing cholinergic nervous system. | Youngjoo Nam Dongung Lee | 2014 | Journal of Traditional Chinese Medicine2014，34，1： | 2 |
