1Prevalence 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

3Deep-learning-based inverse design model for intelligent discovery of organic molecules显示文摘The discovery of high-performance functional materials is crucial for overcoming technical issues in modern industries.Extensive efforts have been devoted toward accelerating and facilitating this process,not only experimentally but also from the viewpoint of materials design.Recently,machine learning has attracted considerable attention,as it can provide rational guidelines for efficient material exploration without time-consuming iterations or prior human knowledge.In this regard,here we develop an inverse design model based on a deep encoder-decoder architecture for targeted molecular design.Inspired by neural machine language translation,the deep neural network encoder extracts hidden features between molecular structures and their material properties,while the recurrent neural network decoder reconstructs the extracted features into new molecular structures having the target properties.In material design tasks,the proposed fully data-driven methodology successfully learned design rules from the given databases and generated promising light-absorbing molecules and host materials for a phosphorescent organic light-emitting diode by creating new ligands and combinatorial rules.Kyungdoc Kim Seokho Kang Jiho Yoo Youngchun Kwon Youngmin Nam Dongseon Lee Inkoo Kim Youn-Suk Choi Yongsik Jung Sangmo Kim Won-Joon Son Jhunmo Son Hyo Sug Lee Sunghan Kim Jaikwang Shin Sungwoo Hwang 2018npj Computational Materials2018,,1:4
4Milan criteria are useful predictors for favorable outcomes in hepatocellular carcinoma patients undergoing liver transplantation after transarterial chemoembolization显示文摘AIM: To evaluate whether the Milan criteria are useful in patients with hepatocellular carcinoma (HCC) who received transarterial chemoembolization (TACE) before liver transplantation (LT). METHODS: Thirty-six HCC patients who fulfilled the Milan criteria after having received TACE and subsequently underwent LT were included (TACE + LT group) in the study. As controls, 21 patients who also met the Milan criteria and underwent LT without prior treatment were selected (LT group). Post-LT clinical outcomes, such as HCC recurrence, survival rate, and histologic features of explanted livers, were compared between the two groups. RESULTS: Baseline characteristics were not different between the two groups. Pre-LT maximal tumor diameter in TACE + LT group was similar to that of LT group (2.0 ± 0.6 cm vs 2.3 ± 0.9 cm; P = 0.10). Post-LT histologic findings also revealed similar maximal tumor diameter in the two groups (2.4 ± 1.4 cm vs 2.3 ± 0.9 cm; P = 0.70). Explanted livers showed similar incidence of unfavorable pathologic features. The morality within 60 d after transplantation was not different between the two groups (8.3% vs 9.5%; P = 0.99). Post-LT 5-year survival rate (57% vs 74%; P = 0.70) and cumulative recurrence rate (8.3% vs 4.8%; P = 0.90) were not significantly different between the two groups. CONCLUSION: The Milan criteria are still a useful selec- tion criteria showing favorable outcomes in HCC patientsreceiving TACE before LT.Do Young Kim Moon Seok Choi Joon Hyoek Lee Kwang Cheol Koh Seung Woon Paik Byung Chul Yoo Sung Wook Shin Sung Wook Choo Young Soo Do Jong Chul Rhee 2006World Journal of Gastroenterology2006,12,43:4
5Intrauterine midgut volvulus without malrotation:Diagnosis from the 'coffee bean sign'显示文摘Fetal midgut volvulus is quite rare, and most cases are associated with abnormalities of intestinal rotation or fixation. We report a case of midgut volvulus without malrotation, associated with a meconium pellet, during the gestation period. This 2.79 kg, 33-wk infant was born via a spontaneous vaginal delivery caused by preterm labor. Prenatal ultrasound showed dilated bowel loops with the appearance of a 'coffee bean sign'. This patient had an unusual presentation with a distended abdomen showing skin discoloration. An emergency laparotomy revealed a midgut volvulus and a twisted small bowel, caused by complicated meconium ileus. Such nonspecific prenatal radiological signs and a low index of suspicion of a volvulus during gestation might delay appropriate surgical management and result in ischemic necrosis of the bowel. Preterm labor, specific prenatal sonographic findings (for example, the coffee bean sign) and bluish discoloration of the abdominal wall could suggest intrauterine midgut volvulus requiring prompt surgical intervention.Jun Seok Park Seong Jae Cha Beom Gyu Kim Yong Seok Kim Yoo Shin Choi In Taik Chang Gwang Jun Kim Woo Seok Lee Gi Hyeon Kim 2008World Journal of Gastroenterology2008,14,9:4
6Retroperitoneal desmoplastic small round cell tumor:Pediatric patient treated with multimodal therapy显示文摘A desmoplastic small round cell tumor (DSRCT) is a rare, aggressive mesenchymal neoplasm. Although a DSRCT can develop at various sites, the intraabdominal site is the most common location. These tumors are found most commonly among young adolescents and the prognosis is extremely poor. Multimodal treatment with surgery, chemotherapy and radiotherapy is very important for these rare cases, and this treatment can improve patient survival. In this report, we describe the case of an 8-year-old boy diagnosed with DSRCT located in the retroperitoneal space. The patient has undergone surgical resection and adjuvant chemoradiation therapy, and is currently alive without disease recurrence.Yong Seok Kim Seong Jae Cha Yoo Shin Choi Beom Gyu Kim Sung Jun Park In Taik Chang 2009World Journal of Gastroenterology2009,15,33:4

8Whole-genome,transcriptome,and methylome analyses provide insights into the evolution of platycoside biosynthesis in Platycodon grandiflorus,a medicinal plant显示文摘Triterpenoid saponins(TSs)are common plant defense phytochemicals with potential pharmaceutical properties.Platycodon grandiflorus(Campanulaceae)has been traditionally used to treat bronchitis and asthma in East Asia.The oleanane-type TSs,platycosides,are a major component of the P.grandiflorus root extract.Recent studies show that platycosides exhibit anti-inflammatory,antiobesity,anticancer,antiviral,and antiallergy properties.However,the evolutionary history of platycoside biosynthesis genes remains unknown.In this study,we sequenced the genome of P.grandiflorus and investigated the genes involved in platycoside biosynthesis.The draft genome of P.grandiflorus is 680.1 Mb long and contains 40,017 protein-coding genes.Genomic analysis revealed that the CYP716 family genes play a major role in platycoside oxidation.The CYP716 gene family of P.grandiflorus was much larger than that of other Asterid species.Orthologous gene annotation also revealed the expansion ofβ-amyrin synthases(bASs)in P.grandiflorus,which was confirmed by tissue-specific gene expression.In these expanded gene families,we identified key genes showing preferential expression in roots and association with platycoside biosynthesis.In addition,wholegenome bisulfite sequencing showed that CYP716 and bAS genes are hypomethylated in P.grandiflorus,suggesting that epigenetic modification of these two gene families affects platycoside biosynthesis.Thus whole-genome,transcriptome,and methylome data of P.grandiflorus provide novel insights into the regulation of platycoside biosynthesis by CYP716 and bAS gene families.Jungeun Kim Sang-Ho Kang Sin-Gi Park Tae-Jin Yang Yi Lee Ok Tae Kim Oksung Chung Jungho Lee Jae-Pil Choi Soo-Jin Kwon Keunpyo Lee Byoung-Ohg Ahn Dong Jin Lee Seung-il Yoo In-Gang Shin Yurry Um Dae Young Lee Geum-Soog Kim Chang Pyo Hong Jong Bhak Chang-Kug Kim 2020Horticulture Research2020,7,1:2

12Hypothyroidism affects astrocyte and microglial morphology in type 2 diabetes显示文摘In the present study,we investigated the effects of hypothyroidism on the morphology of astrocytes and microglia in the hippocampus of Zucker diabetic fatty rats and Zucker lean control rats.To induce hypothyroidism,Zucker lean control and Zucker diabetic fatty rats at 7 weeks of age orally received the vehicle or methimazole,an anti-thyroid drug,treatment for 5 weeks and were sacrificed at 12 weeks of age in all groups for blood chemistry and immunohistochemical staining.In the methimazole-treated Zucker lean control and Zucker diabetic fatty rats,the serum circulating triiodothyronine(T3)and thyroxine(T4)levels were significantly decreased compared to levels observed in the vehicle-treated Zucker lean control or Zucker diabetic fatty rats.This reduction was more prominent in the methimazole-treated Zucker diabetic fatty group.Glial fibrillary acidic protein immunoreactive astrocytes and ionized calcium-binding adapter molecule 1(Iba-1)-immunoreactive microglia in the Zucker lean control and Zucker diabetic fatty group were diffusely detected in the hippocampal CA1 region and dentate gyrus.There were no significant differences in the glial fibrillary acidic protein and Iba-1 immunoreactivity in the CA1 region and dentate gyrus between Zucker lean control and Zucker diabetic fatty groups.However,in the methimazole-treated Zucker lean control and Zucker diabetic fatty groups,the processes of glial fibrillary acidic protein immunoreactive astrocytes and Iba-1 immunoreactive microglia,were significantly decreased in both the CA1region and dentate gyrus compared to that in the vehicle-treated Zucker lean control and Zucker diabetic fatty groups.These results suggest that diabetes has no effect on the morphology of astrocytes and microglia and that hypothyroidism during the onset of diabetes prominently reduces the processes of astrocytes and microglia.Sung Min Nam Yo Na Kim Dae Young Yoo Sun Shin Yi Jung Hoon Choi In Koo Hwang Je Kyung Seong Yeo Sung Yoon 2013Neural Regeneration Research2013,8,26:2
13Enhanced third-harmonic generation by manipulating the twist angle of bilayer graphene显示文摘Twisted bilayer graphene(tBLG)has received substantial attention in various research fields due to its unconventional physical properties originating from Moire superlattices.The electronic band structure in tBLG modified by interlayer interactions enables the emergence of low-energy van Hove singularities in the density of states,allowing the observation of intriguing features such as increased optical conductivity and photocurrent at visible or near-infrared wavelengths.Here,we show that the third-order optical nonlinearity can be considerably modified depending on the stacking angle in tBLG.The third-harmonic generation(THG)efficiency is found to significantly increase when the energy gap at the van Hove singularity matches the three-photon resonance of incident light.Further study on electrically tuneable optical nonlinearity reveals that the gate-controlled THG enhancement varies with the twist angle in tBLG,resulting in a THG enhanced up to 60 times compared to neutral monolayer graphene.Our results prove that the twist angle opens up a new way to control and increase the optical nonlinearity.of tBLG,,suggesting rotation-induced tuneable nonlinear optics in stacked two-dimensional material systems.Seongju Ha Nam Hun Park Hyeonkyeong Kim Jiseon Shin Jungseok Choi Sungmin Park Ji-Yun Moon Kwanbyung Chae Jeil Jung Jae-Hyun Lee Youngdong Yoo Ji-Yong Park Kwang Jun Ahn Dong-Il Yeom 2021Light(Science & Applications)2021,10,2:1
