| 1 | Differential diagnosis of left-sided abdominal pain:Primary epiploic appendagitis vs colonic diverticulitis显示文摘AIM:To investigate the clinical characteristics of left primary epiploic appendagitis and to compare them with those of left colonic diverticulitis.METHODS:We retrospectively reviewed the clinical records and radiologic images of the patients who presented with left-sided acute abdominal pain and had computer tomography(CT) performed at the time of presentation showing radiological signs of left primary epiploic appendagitis(PEA) or left acute colonic diverticulitis(ACD) between January 2001 and December 2011. A total of 53 consecutive patients were enrolled and evaluated. We also compared the clinical characteristics,laboratory findings,treatments,and clinical results of left PEA with those of left ACD.RESULTS:Twenty-eight patients and twenty-five patients were diagnosed with symptomatic left PEA and ACD,respectively. The patients with left PEA had focal abdominal tenderness on the left lower quadrant(82.1%). On CT examination,most(89.3%) of the patients with left PEA were found to have an oval fatty mass with a hyperattenuated ring sign. In cases of left ACD,the patients presented with a more diffuse abdominal tenderness throughout the left side(52.0%vs 14.3%; P = 0.003). The patients with left ACD had fever and rebound tenderness more often than those with left PEA(40.0% vs 7.1%,P = 0.004; 52.0% vs14.3%,P = 0.003,respectively). Laboratory abnormalities such as leukocytosis were also more frequently observed in left ACD(52.0% vs 15.4%,P = 0.006).CONCLUSION:If patients have left-sided localized abdominal pain without associated symptoms or laboratory abnormalities,clinicians should suspect the diagnosis of PEA and consider a CT scan. | Jeong Ah Hwang Sun Moon Kim Hyun Jung Song Yu Mi Lee Kyung Min Moon Chang Gi Moon Hoon Sup Koo Kyung Ho Song Yong Seok Kim Tae Hee Lee Kyu Chan Huh Young Woo Choi Young Woo Kang Woo Suk Chung | 2013 | World Journal of Gastroenterology2013，19，40： | 6 |

| 3 | Efficient photovoltaic effect in graphene/h-BN/silicon heterostructure self-powered photodetector显示文摘Graphene(Gr)/Si-based optoelectronic devices have attracted a lot of academic attention due to the simpler fabrication processes,low costs,and higher performance of their two-dimensional(2D)/three-dimensional(3D)hybrid interfaces in Schottky junction that promotes electron-hole separation.However,due to the built-in potential of Gr/Si as a photodetector,the Iph/Idark ratio is often hindered near zero-bias at relatively low illumination intensity.This is a major drawback in self-powered photodetectors.In this study,we have demonstrated a self-powered van der Waals heterostructure photodetector in the visible range using a Gr/hexagonal boron nitride(h-BN)/Si structure and clarified that the thin h-BN insertion can engineer asymmetric carrier transport and avoid interlayer coupling at the interface.The dark current was able to be suppressed by inserting an h-BN insulator layer,while maintaining the photocurrent with minimal decrease at near zero-bias.As a result,the normalized photocurrent-to-dark ratio(NPDR)is improved more than 104 times.Also,both Iph/Idark ratio and detectivity,increase by more than 104 times at−0.03 V drain voltage.The proposed Gr/h-BN/Si heterostructure is able to contribute to the introduction of next-generation photodetectors and photovoltaic devices based on graphene or silicon. | Ui Yeon Won Boo Heung Lee Young Rae Kim Won Tae Kang Ilmin Lee Ji Eun Kim Young Hee Lee Woo Jong Yu | 2021 | Nano Research2021，14，6： | 2 |

| 12 | Rice pollen-specific OsRALF17 and OsRALF19 are essential for pollen tube growth显示文摘Pollen tube growth is essential for successful double fertilization, which is critical for grain yield in crop plants. Rapid alkalinization factors(RALFs) function as ligands for signal transduction during fertilization. However, functional studies on RALF in monocot plants are lacking.Herein, we functionally characterized two pollen-specific RALFs in rice(Oryza sativa) using multiple clustered regularly interspaced palindromic repeats(CRISPR)/CRISPR-associated protein 9-induced loss-of-function mutants,peptide treatment, expression analyses, and tag reporter lines. Among the 41 RALF members in rice, OsRALF17 was specifically expressed at the highest level in pollen and pollen tubes.Exogenously applied OsRALF17 or OsRALF19peptide inhibited pollen tube germination and elongation at high concentrations but enhanced tube elongation at low concentrations, indicating growth regulation. Double mutants of OsRALF17 and OsRALF19(ralf17/19) exhibited almost full male sterility with defects in pollen hydration, germination, and tube elongation,which was partially recovered by exogenous treatment with OsRALF17 peptide. This study revealed that two partially functionally redundant OsRALF17 and OsRALF19 bind to Oryza sativa male-gene transfer defective 2(OsMTD2) and transmit reactive oxygen species signals for pollen tube germination and integrity maintenance in rice. Transcriptomic analysis confirmed their common downstream genes, in osmtd2 and ralf17/19. This study provides new insights into the role of RALF, expanding our knowledge of the biological role of RALF in regulating rice fertilization. | Eui‐Jung Kim Ji‐Hyun Kim Woo‐Jong Hong Eun Young Kim Myung‐Hee Kim Su Kyoung Lee Cheol Woo Min Sun Tae Kim Soon Ki Park Ki‐Hong Jung Yu‐Jin Kim | 2023 | Journal of Integrative Plant Biology2023，65，9： | 0 |
| 13 | Delayed pseudoaneurysm formation of the carotid artery following the oral cavity injury in a child:A case report显示文摘BACKGROUND An impalement injury of the oral cavity is a common traumatic injury in children.In most cases,it is not accompanied by sequelae,but if foreign body residues are not found due to a minor injury,they may result in inflammatory responses and delayed vascular injuries in the surrounding tissues.Without early diagnosis and appropriate initial management,residual foreign bodies can cause serious complications and even mortality in some cases.CASE SUMMARY A 9-year-old boy suffered an intra-oral injury by a wooden chopstick,and the patient was discharged from the hospital after receiving conservative treatment for the injury.However,the patient was readmitted to the hospital due to intraoral bleeding,and since neck hematoma and right internal carotid artery pseudoaneurysm formation were detected on computed tomography,emergency surgery was performed.A remnant fragment of a wooden chopstick was found during the operation,and a delayed rupture of the internal carotid artery caused by the foreign body was also found.CONCLUSION The failure of early detection and diagnosis of a residual foreign body may result in delayed vascular rupture. | Byeoung Hoon Chung Mi Rin Lee Jae Do Yang Hee Chul Yu Yong Tae Hong Hong Pil Hwang | 2021 | World Journal of Clinical Cases2021，9，16： | 0 |
| 14 | Tuning the inhomogeneous charge transport in ZnO interfaces for ultrahigh on/off ratio top-gated field-effect-transistor arrays显示文摘The interface between oxide/oxide layers shows an inhomogeneous charge transport behavior,which reveals a high conductivity owing to interface-doped.One typical example is the hetero-interface between ZnO film and other wide band gap oxides(e.g.,Al_(2)O_(3),TiO_(2),and HfO_(2)).It is thus quite evident that the ZnO/other oxides hetero-interface contains high density electron carriers effectively screening the gate-induced electric field.Thus,an extremely weak gate modulation in ZnO film was showed,resulting in very low on/off ratio of 1.69 in top-gate field-effect-transistor(TG-FET)configuration.So,to extend the usage of ZnO TG-FET is not quite possible toward further practical application.Herein,we clarified the correlation of inhomogeneous region in oxide/oxide hetero-junction by systematically study.Our work suggests that a self-assembly of molecules(SAM)buffer layer is suitable for tuning the inhomogeneous charge transport in ZnO film,which not only reduces the interface trap density,but also effectively enhances the gate electric field modulation at the hetero-interface.We further report the robust fabrication of TG-FET arrays based on ZnO thin film,using an ultra-thin alkylphosphonic acid molecule monolayer as buffer layer.Our device demonstrates a pronounced ultrahigh on/off ratio of≥10^(8),which is 8-order of magnitude higher than that of a device without buffer layer.For the highly reliable arrays,our device exhibits a high yield of over 93%with an average on/off ratio of^10^(7) across the entire wafer scale,mobility(18.5 cm^(2)/(V·s)),an extended bias-stressing(~2,000 s)and long-stability(~150 days)under ambient conditions. | Thanh Luan Phan Dinh Loc Duong Tuan Khanh Chau Sidi Fan Won Tae Kang Thi Suong Le Hyun Yong Song Linfeng Sun Van Tu Vu Min Ji Lee Quoc An Vu Young Hee Lee Woo Jong Yu | 2020 | Nano Research2020，13，11： | 0 |
