| 1 | In-situ formation of MOF derived mesoporous Co3N/amorphous N-doped carbon nanocubes as an efficient electrocatalytic oxygen evolution reaction显示文摘The suitable materials,metal nitrides,are a promising class of electrocatalyst materials for a highly efficient oxygen evolution reaction (OER) because they exhibit superior intrinsic conductivity and have higher sustainability than oxide-based materials.To our knowledge,for the first time,we report a designable synthesis of three-dimensional (3D) and mesoporous Co3N@ amorphous N-doped carbon (AN-C) nanocubes (NCs) with well-controlled open-framework structures via monodispersed Co3[Co(CN)6]2 Prussian blue analogue (PBA) NC precursors using in situ nitridation and calcination processes.Co3N@AN-C NCs (2 h) demonstrate better OER activity with a remarkably low Tafel plot (69.6 mV-dec-1),low overpotential of 280 mV at a current density of 10 mA-crrf2.Additionally,excellent cycling stability in alkaline electrolytes was exhibited without morphological changes and voltage elevations,superior to most reported hierarchical structures of transition-metal nitride particles.The presented strategy for synergy effects of metal-organic frameworks (MOFs)-derived transition-metal nitrides-carbon hybrid nanostructures provides prospects for developing high-performance and advanced electrocatalyst materials. | Bong Kyun Kang Seo Young Im Jooyoung Lee Sung Hoon Kwag Seok Bin Kwon SintayehuNibret Tiruneh Min-Jun Kim Jung Ho Kim Woo Seok Yang Byungkwon Lim Dae Ho Yoon | 2019 | Nano Research2019,12,7: | 8 |
| 2 | Two-dimensional physical habitat modeling of effects of habitat structures on urban stream restoration显示文摘River corridors, even if highly modified or degraded, still provide important habitats for numerous biological species, and carry high aesthetic and economic values. One of the keys to urban stream restoration is recovery and maintenance of ecological flows sufficient to sustain aquatic ecosystems. In this study, the Hongje Stream in the Seoul metropolitan area of Korea was selected for evaluating a physically-based habitat with and without habitat structures. The potential value of the aquatic habitat was evaluated by a weighted usable area (WUA) using River2D, a two-dimensional hydraulic model. The habitat suitability for Zacco platypus in the Hongje Stream was simulated with and without habitat structures. The computed WUA values for the boulder, spur dike, and riffle increased by about 2%, 7%, and 131%, respectively, after their construction. Also, the three habitat structures, especially the riffle, can contribute to increasing hydraulic heterogeneity and enhancing habitat diversity. | Dongkyun IM Hyeongsik KANG | 2011 | Water Science and Engineering2011,4,4: | 8 |
| 3 | Clinical and endoscopic characteristics of drug-induced esophagitis显示文摘AIM: To investigate clinical, endoscopic and pathological characteristics of drug-induced esophagitis.METHODS: Data for patients diagnosed with drug-induced esophagitis from April 2002 to May 2013 was reviewed. Patients diagnosed with malignancy, viral or fungal esophagitis were excluded. Clinical, endoscopic and pathological characteristics of patients diagnosed with drug-induced esophagitis were analyzed.RESULTS: Seventy-eight patients were diagnosed with drug-induced esophagitis. Their mean age was 43.9 ± 18.9 years and 35.9% were male. Common symptoms were chest pain(71.8%), odynophagia(38.5%) and dysphagia(29.5%). The endoscopic location was in the middle third of esophagus in 78.2%. Endoscopic findings were ulcer(82.1%), erosion(17.9%), ulcer with bleeding(24.4%), coating with drug material(5.1%), impacted pill fragments(3.8%) and stricture(2.6%). Kissing ulcers were observed in 43.6%. The main causative agents were antibiotics and non-steroidal antiinflammatory drugs. All the patients were treated with proton pump inhibitors(PPIs) or sucralfate, and the causative drugs were discontinued. Nineteen patients with drug-induced esophagitis were followed up with endoscopy and revealed normal findings, scars or healing ulcers.CONCLUSION: Drug-induced esophagitis mainly presents as chest pain, odynophagia and dysphagia, and may be successfully treated with PPIs and discontinuation of the causative drug. Kissing ulcers were observed in 43.6%. | Su Hwan Kim Ji Bong Jeong Ji Won Kim Seong-Joon Koh Byeong Gwan Kim Kook Lae Lee Mee Soo Chang Jong Pil Im Hyoun Woo Kang Cheol Min Shin | 2014 | World Journal of Gastroenterology2014,20,31: | 7 |

| 10 | Trends and risk factors of elderly-onset Crohn’s disease: A nationwide cohort study显示文摘BACKGROUND The incidence of inflammatory bowel disease(IBD)is increasing in Asia.Numerous risk factors associated with IBD development have been investigated.AIM To investigate trends and environmental risk factors of Crohn’s disease(CD)diagnosed in persons aged≥40 years in South Korea.METHODS Using the National Health Insurance Service database,a total of 14060821 persons aged>40 years who underwent national health screening in 2009 were followed up until December 2017.Patients with newly diagnosed CD were enrolled and compared with non-CD cohort.CD was identified according to the International Classification of Diseases 10th revision and the rare/intractable disease registration program codes from the National Health Insurance Service database.The mean follow-up periods was 7.39 years.Age,sex,diabetes,hypertension,smoking,alcohol consumption,regular exercise,body mass index,anemia,chronic kidney disease(CKD)and dyslipidemia were adjusted for in the multivariate analysis model.RESULTS During the follow-up,1337(1.33/100000)patients developed CD.Men in the middle-aged group(40-64 years)had a higher risk than women[adjusted hazard ratio(aHR)1.46,95%confidence interval(CI):1.29-1.66];however,this difference tended to disappear as the age of onset increases.In the middle-aged group,patients with a history of smoking[(aHR 1.46,95%CI:1.19-1.79)and anemia(aHR 1.85,95%CI:1.55-2.20)]had a significantly higher CD risk.In the elderly group(age,≥65 years),ex-smoking and anemia also increased the CD risk(aHR 1.68,95%CI:1.22-2.30)and 1.84(95%CI:1.47-2.30,respectively).Especially in the middle-aged group,those with CKD had a statistically elevated CD risk(aHR 1.37,95%CI:1.05-1.79).Alcohol consumption and higher body mass index showed negative association trend with CD incidence in both of the age groups.[Middle-aged:aHR 0.77(95%CI:0.66-0.89)and aHR 0.73(95% CI:0.63-0.84),respectively][Elderly-group:aHR 0.57(95% CI:0.42-0.78)and aHR 0.84(95%CI 0.67-1.04),respectively].For regular physical activity and dyslipidemia,negative correlation between CD incidences was proved only in the middle-aged group[aHR 0.88(95%CI:0.77-0.89)and aHR 0.81(95%CI:0.68-0.96),respectively].CONCLUSION History of cigarette smoking,anemia,underweight and CKD are possible risk factors for CD in Asians aged>40 years. | Jung Min Moon Eun Ae Kang Kyungdo Han Seung Wook Hong Hosim Soh Seona Park Jooyoung Lee Hyun Jung Lee Jong Pil Im Joo Sung Kim | 2020 | World Journal of Gastroenterology2020,26,4: | 2 |
| 11 | Inhibition of BET selectively eliminates undifferentiated pluripotent stem cells显示文摘Embryonic stem cells(ESCs) maintain their cellular identity through the systematic regulation of master transcription factors and chromatin remodeling complexes. Recent work has shown that the unusually large-scale enhancers—namely super-enhancers(SEs), on which BRD4, a member of the bromodomain and extraterminal domain(BET) family is highly enriched—could regulate pluripotency-related transcription factors. Moreover, inhibition of BRD4 binding on SEs has been shown to induce the differentiation of ESCs. However, the underlying mechanism of BRD4 inhibition-mediated stem cell differentiation remains elusive. Here we show that both mouse and human ESCs lose their capacity for self-renewal upon treatment with JQ1, a selective inhibitor of BET family including BRD4, with rapid suppression of pluripotency-associated genes. Notably, a high concentration of JQ1 could selectively eliminate ESCs via apoptosis, without affecting the functionality of differentiated somatic cells from ESCs, suggesting that inhibition of BET may have a beneficial effect on the development of pluripotent stem cell-based cell therapy. | Jung Hyun Im Seon In Hwang Jong-Wan Kim soon-Jung Park Kyu-ree Kang Jueng Soo You Kee Pyo Kim Sung-Hwan Moon Hyuk-Jin Cha Hyung-Min Chung Hans R.
