2Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite.Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon 2009World Journal of Gastroenterology2009,15,1:15
3Clinicopathologic factors influencing the accuracy of EUS for superficial esophageal carcinoma显示文摘AIM:To identify clinicopathologic factors influencing the accuracy of a high-frequency catheter probe endoscopic ultrasonography(EUS)for superficial esophageal carcinomas(SECs).METHODS:A total of 126 patients with endoscopically suspected SEC,who underwent EUS and curative treatment at Pusan National University Hospital during2005-2013,were enrolled.We reviewed the medical records of the 126 patients and compared EUS findings with histopathologic results according to clinicopathologic factors.RESULTS:A total of 114 lesions in 113 patients were included in the final analysis.The EUS assessment of tumor invasion depth was accurate in 78.9%(90/114)patients.Accuracy did not differ according to histologic type,tumor differentiation,tumor location,or macroscopic shape.However,accuracy significantly decreased for tumors≥3 cm in size(P=0.002).Overestimation and underestimation of the invasion depth occurred for 11(9.6%)and 13 lesions(11.4%),respectively.In multivariate analyses,tumor size≥3 cm was the only factor significantly associated with EUS accuracy(P=0.031),and was specifically associated with the underestimation of invasion depth.CONCLUSION:EUS using a high-frequency catheter probe generally provides highly accurate assessments of SEC invasion depth,but its accuracy decreases for tumors≥3 cm.Jung Im Jung Gwang Ha Kim Hoseok I Do Youn Park Tae Kyun Kim Young Hwa Cho Yong Wan Sung Mun Ki Choi Bong Eun Lee Geun Am Song 2014World Journal of Gastroenterology2014,20,20:9
4Removal of primary iron rich phase from aluminum-silicon melt by centrifugal separation显示文摘Recycling is a major consideration in continued aluminum use due to the enormous demand for high quality products. Some impurity elements gradually accumulate through the repetitive reuse of aluminum alloy scrap. Of them, the iron content should be suppressed under the allowed limit. In the present research, a novel separation method was introduced to remove primary iron-rich intermetallic compounds by centrifugation during solidification of Al-Si-Fe alloys. This method does not use the density difference between two phases as in other centrifugal methods, but uses the order of solidification in Al-Si-Fe alloys, because iron promotes the formation of intermetallic compounds with other alloying elements as a primary phase. Two Al-Si-Fe alloys which have different iron contents were chosen as the starting materials. The iron-rich phase could be efficiently removed by centrifuging under a centrifugal force of 40 g. Coarse intermetallic compounds were found in the sample inside the crucible, while rather fine intermetallic compounds were found in the sample outside the crucible. Primary intermetallic compounds were linked to each other via aluminum-rich matrix, and formed like a network. The highest iron removal fraction is 67% and the lowest one is 7% for Al-12Si-1.7Fe alloy. And they are 82% and 18% for Al-12Si-3.4Fe alloy, respectively.Seong Woo Kim Un Ho Im Hyeong Cheol Cha Se Hyeong Kim Ji Eun Jang Ki Young Kim 2013China Foundry2013,10,2:8
5In-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 2019Nano Research2019,12,7:8
6An inside-out vein graft filled with platelet-rich plasma for repair of a short sciatic nerve defect in rats显示文摘Platelet-rich plasma containing various growth factors can promote nerve regeneration. An inside-out vein graft can substitute nerve autograft to repair short nerve defects. It is hypothesized that an inside-out vein graft filled with platelet-rich plasma shows better effects in the repair of short sciatic nerve defects. In this study, an inside-out vein autograft filled with platelet-rich plasma was used to bridge a 10 mm-long sciatic nerve defect in rats. The sciatic nerve function of rats with an inside-out vein autograft filled with platelet-rich plasma was better improved than that of rats with a simple inside-out vein autograft. At 6 and 8 weeks, the sciatic nerve function of rats with an inside-out vein autograft filled with platelet-rich plasma was better than that of rats undergoing nerve autografting. Compared with the sciatic nerve repaired with a simple inside-out vein autograft, the number of myelinated axons was higher, axon diameter and myelin sheath were greater in the sciatic nerve repaired with an inside-out vein autograft filled with platelet-rich plasma and they were similar to those in the sciatic nerve repaired with nerve autograft. These findings suggest that an inside-out vein graft filled with platelet-rich plasma can substitute nerve autograft to repair short sciatic nerve defects.Ji Yeong Kim Woo Joo Jeon Dong Hwee Kim Im Joo Rhyu Young Hwan Kim Inchan Youn Jong Woong Park 2014Neural Regeneration Research2014,9,14:6
7Scalp electroacupuncture at the Baihui acupoint (DU 20) improves functional recovery in rats with cerebral ischemia Association with increased expression of vascular endothelial growth factors显示文摘In this study, we induced cerebral infarction in rats by occluding the right middle cerebral artery, and tested the effects of electroacupuncture at the Baihui acupoint (DU 20). Motor and sensory function was tested using Garcia’s scale and motor weakness grading, and the expression of vascular endothelial growth factor in the brain was quantified using immunoblotting and immunohistochemistry. We found that scalp electroacupuncture at DU 20 significantly improved motor performance and sensory function in rats with stroke, and this was accompanied by an increased expression of vascular endothelial growth factor in the ischemic brain tissue and peri-ischemic area. In addition, Pearson correlation analysis showed that the improvements in functional recovery were correlated with the increased expression of vascular endothelial growth factor.Min-Wook Kim You Chul Chung Hee Chan Jung Moon-Seo Park Young-Min Han Yong-An Chung Lee-So Maeng Sang-In Park Jiyeon Lim Seung Chan Kim Woo-Seok Im Jin Young Chung Minky Kim Manho Kim 2011Neural Regeneration Research2011,6,36:4

12来自一项艾日布林联合吉西他滨对比紫杉醇联合吉西他滨作为HER2阴性转移性乳腺癌的一线化疗的Ⅱ期、多中心、随机试验的包含神经病变相关量表的生活质量结果:韩国癌症研究组试验(KCSG BR13-11)显示文摘背景与目的一项比较艾日布林联合吉西他滨(eribulin plus gemcitabine,EG)或紫杉醇联合吉西他滨(paclitaxel plus gemcitabine,PG)作为转移性乳腺癌(metastatic breast cancer,MBC)患者一线化疗方案的II期临床试验发现,EG方案的神经毒性较低,但疗效与PG方案相似。在本研究中,我们分析了该临床实验中的癌症患者生命质量测评量表–紫杉烷(functional assessment of cancer therapy-taxane,FACT-Taxane)问卷评分以确定他们的生活质量(quality of life,QoL)。方法使用韩国版的FACT-Taxane问卷评估QoL。在评估基线之后,前12个疗程中每2个疗程评估1次QoL,之后每3个疗程评估1次QoL。使用线性混合模型评估EG组和PG组QoL的差异。结果在118例入组患者中,117例在基线时回复了FACT-Taxane问卷,PG组中有1例患者没有回复。EG组和PG组之间的基线QoL评分没有差异。在治疗期间,除了第11个疗程外,在第2–13个化疗疗程后,PG组紫杉烷亚量表评分显著高于EG组(均P<0.05)。神经病变特异性分析显示PG组患者的神经病症状比EG组患者更早出现且更严重(P<0.001)。结论在我们的QoL分析中,与PG方案相比,EG方案延迟并减少神经病变的发生。因此,艾日布林是MBC一线化疗药物紫杉醇的合理替代品。Ji‑Yeon Kim Seri Park Seock‑Ah Im Sung‑Bae Kim Joohyuk Sohn Keun Seok Lee Yee Soo Chae Ki Hyeong Lee Jee Hyun Kim Young‑Hyuck Im Tae‑Yong Kim Kyung‑Hun Lee Jin‑Hee Ahn Gun Min Kim In Hae Park Soo Jung Lee Hye Sook Han Se Hyun Kim Kyung Hae Jung Yeon Hee Park Korean Cancer Study Group 2019癌症2019,38,8:2
13Downregulated miR-18b-5p triggers apoptosis by inhibition of calcium signaling and neuronal cell differentiation in transgenic SOD1(G93A)mice and SOD1(G17S and G86S)ALS patients显示文摘Background:MicroRNAs(miRNAs)are endogenous non-coding RNAS that regulate gene expression at the post-transcriptional level and are key modulators in neurodegenerative diseases.Overexpressed miRNAs play an important role in amyotrophic lateral sclerosis(ALS);however,the pathogenic mechanisms of deregulated miRNAS are still unclear.Methods:We aimed to assess the dysfunction of RNAS or miRNAs in fALS(SOD1 mutations).We compared the RNA-seq of subcellular fractions in NSC-34 WT(hSOD1)and MT(hSOD1(G93A))cells to find altered RNAs or miRNAs.We identified that Hif1a and Mef2c were upregulated,and Mctp1 and Rarb were downregulated in the cytoplasm of NSC-34 MT cells.Results:SOD1 mutations decreased the level of miR-18b-5p.Induced Hif1a which is the target for miR-18b increased Mef2c expression as a transcription factor.Mef2c upregulated miR-206 as a transcription factor.Inhibition of Mctp1 and Rarb,which are targets of miR-206,induced intracellular Ca^2+ levels and reduced cell differentiation,respectively.The miR-18b-5p pathway was also observed in G93A Tg mice,fALS(G86S)patient,and iPSC-derived motor neurons from fALS(G17S)patient.Conclusions:Our data indicate that SOD1 mutation decreases miR-18b-5p,which sequentially regulates Hif1a,Mef2c,miR-206,Mctp1 and Rarb in fALS-linked SOD1 mutation.These results provide new insights into the downregulation of miR-18b-5p-dependent pathogenic mechanisms of ALS.Ki Yoon Kim Yu Ri Kim Kyung Won Choi Mijung Lee Somyung Lee Wooseok Im Je-Young Shin Jin Young Kim Yoon Ho Hong Manho Kim Jong-ll Kim Jung-Joon Sung 2020Translational Neurodegeneration2020,9,3:2
