| 1 | Programmed death ligand-1 expression and its prognostic role in esophageal squamous cell carcinoma显示文摘AIM To investigate the expression and prognostic role of programmed death ligand-1(PD-L1) in locally advanced esophageal squamous cell carcinoma(ESCC).METHODS A total of 200 patients with ESCC who underwent radical esophagectomy with standard lymphadenectomy as the initial definitive treatment in Seoul National University Hospital from December 2000 to April 2013 were eligible for this analysis. Tissue microarrays were constructed by collecting tissue cores from surgical specimens, and immunostained with antibodies directed against PD-L1, p16, and c-Met. Medical records were reviewed retrospectively to assess clinical outcomes. Patients were divided into two groups by PD-L1 status, and significant differences in clinicopathologic characteristics between the two groups were assessed. RESULTS Tumor tissues from 67 ESCC patients(33.5%) were PDL1-positive. Positive p16 expression was observed in 21 specimens(10.5%). The H-score for c-Met expression was ≥ 50 in 42 specimens(21.0%). Although PDL1-positivity was not significantly correlated with any clinical characteristics including age, sex, smoking/alcoholic history, stage, or differentiation, H-scores for c-Met expression were significantly associated with PDL1-positivity(OR = 2.34, 95%CI: 1.16-4.72, P = 0.017). PD-L1 expression was not significantly associated with a change in overall survival(P = 0.656). In contrast, the locoregional relapse rate tended to increase(P = 0.134), and the distant metastasis rate was significantly increased(HR = 1.72, 95%CI: 1.01-2.79, P = 0.028) in patients with PD-L1-positive ESCC compared to those with PD-L1-negative ESCC.CONCLUSION PD-L1 expression is positively correlated with c-Met expression in ESCC. PD-L1 may play a critical role in distant failure and progression of ESCC. | Ryul Kim Bhumsuk Keam Dohee Kwon Chan-Young Ock Miso Kim Tae Min Kim Hak Jae Kim Yoon Kyung Jeon In Kyu Park Chang Hyun Kang Dong-Wan Kim Young Tae Kim Dae Seog Heo | 2016 | World Journal of Gastroenterology2016，22，37： | 14 |
| 2 | Computational discovery of p-type transparent oxide semiconductors using hydrogen descriptor显示文摘The ultimate transparent electronic devices require complementary and symmetrical pairs of n-type and p-type transparent semiconductors.While several n-type transparent oxide semiconductors like InGaZnO and ZnO are available and being used in consumer electronics,there are practically no p-type oxides that are comparable to the n-type counterpart in spite of tremendous efforts to discover them.Recently,high-throughput screening with the density functional theory calculations attempted to identify candidate p-type transparent oxides,but none of suggested materials was verified experimentally,implying need for a better theoretical predictor.Here,we propose a highly reliable and computationally efficient descriptor for p-type dopability—the hydrogen impurity energy.We show that the hydrogen descriptor can distinguish well-known p-type and n-type oxides.Using the hydrogen descriptor,we screen most binary oxides and a selected pool of ternary compounds that covers Sn^(2+)-bearing and Cu^(1+)-bearing oxides as well as oxychalcogenides.As a result,we suggest La_(2)O_(2)Te and CuLiO as promising p-type oxides. | Kanghoon Yim Yong Youn Miso Lee Dongsun Yoo Joohee Lee Sung Haeng Cho Seungwu Han | 2018 | npj Computational Materials2018，，1： | 2 |

| 7 | Determination of nitrogen reduction levels necessary to reach groundwater quality targets in Slovenia显示文摘Within a collaborative project between Slovenian Environment Agency(ARSO)and Research Center Jülich(FZJ),nitrogen reduction levels necessary to reach groundwater quality targets in Slovenia were assessed.For this purpose the hydrological model GROWA–DENUZ was coupled with agricultural N balances and applied consistently to the whole territory of Slovenia in a spatial resolution of 100×100 m.GROWA was used to determine the water balance in Slovenia for the hydrologic period 1971–2000.Simultaneously,the displaceable N load in soil was assessed from agricultural Slovenian N surpluses for 2011and the atmospheric N deposition.Subsequently,the DENUZ model was used to assess the nitrate degradation in soil and,in combination with the percolation water rates from the GROWA model,to determine nitrate concentration in the leachate.The areas showing predicted nitrate concentrations in the leachate above the EU groundwater quality standard of 50 mg NO3-/L have been identified as priority areas for implementing nitrogen reduction measures.For these'hot spot'areas DENUZ was used in a backward mode to quantify the maximal permissible nitrogen surplus levels in agriculture to guarantee a nitrate concentration in percolation water below 50 mg NO3-/L.Model results indicate that additional N reduction measures should be implemented in priority areas rather than area-covering.Research work will directly support the implementation of the European Union Water Framework Directive in Slovenia,e.g.,by using the maximal permissible nitrogen surplus levels as a framework for the derivation of regionally adapted and hence effective nitrogen reduction measures. | Miso Andelov Ralf Kunkel Jo?e Uhan Frank Wendland | 2014 | Journal of Environmental Sciences2014，26，9： | 0 |
| 8 | Characterization of lattice parameters gradient of Cu(In1-xGax)Se2 absorbing layer in thin-film solar cell by glancing incidence X-ray diffraction technique显示文摘In or Ga gradients in the Cu(In1-xGax)Se2(CIGS)absorbing layer lead to change the lattice parameters of the absorbing layer,giving rise to the bandgap grading in the absorbing layer which is directly associated with the degree of absorbing ability of the CIGS solar cell.We tried to characterize the depth profile of the lattice parameters of the CIGS absorbing layer using a glancing incidence X-ray diffraction(GIXRD)technique,and then investigate the bandgap grading of the CIGS absorbing layer.When the glancing incident angle increased from 0.50 to 5.00°,the a and c lattice parameters of the CIGS absorbing layer gradually decreased from 5.7776(3)to 5.6905(2)?,and 11.3917(3)to 11.2114(2)?,respectively.The depth profile of the lattice parameters as a function of the incident angle was consistent with vertical variation in the compositionof In or Ga with depth in the absorbing layer.The variation of the lattice parameters was due to the difference between the ionic radius of In and Ga co-occupying at the same crystallographic site.According to the results of the depth profile of the refined parameters using GIXRD data,the bandgap of the CIGS absorber layer was graded over a range of 1.222-1.532 eV.This approach allows to determine the In or Ga gradients in the CIGS absorbing layer,and to nondestructively guess the bandgap depth profile through the refinement of the lattice parameters using GIXRD data on the assumption that the changes of the lattice parameters or unit-cell volume follow a good approximation to Vegard’s law. | Yong-Il Kim Ki-Bok Kim Miso Kim | 2020 | Journal of Materials Science & Technology2020，47，16： | 0 |
| 9 | Circulating small extracellular vesicles promote proliferation and migration of vascular smooth muscle cells via AXL and MerTK activation显示文摘The proliferation and migration of vascular smooth muscle cells(VSMCs)after vascular injury lead to neointimal hyperplasia,thus aggravating vascular diseases.However,the molecular mechanisms underlying neointima formation are not fully elucidated.Extracellular vesicles(EVs)are mediators of various intercellular communications.The potential of EVs as regulators in cardiovascular diseases has raised significant interest.In the current study we investigated the role of circulating small extracellular vesicles(csEVs),the most abundant EVs(10^(10)EVs/mL serum)in VSMC functions.csEVs were prepared from bovine,porcine or rat serum.We showed that incubation with csEVs(0.5×10^(10)−2×10^(10))dose-dependently enhanced the proliferation and migration of VSMCs via the membrane phosphatidylserine(PS).In rats with ligation of right carotid artery,we demonstrated that application of csEVs in the ligated vessels aggravated neointima formation via interaction of membrane PS with injury.Furthermore,incubation with csEVs markedly enhanced the phosphorylation of AXL and MerTK in VSMCs.Pretreatment with BSM777607(pan-TAM inhibitor),bemcentinib(AXL inhibitor)or UNC2250(MerTK inhibitor)blocked csEV-induced proliferation and migration of VSMCs.We revealed that csEV-activated AXL and MerTK shared the downstream signaling pathways of Akt,extracellular signal-regulated kinase(ERK)and focal adhesion kinase(FAK)that mediated the effects of csEVs.We also found that csEVs increased the expression of AXL through activation of transcription factor YAP,which might constitute an AXL-positive feedback loop to amplify the signals.Finally,we demonstrated that dual inhibition of AXL/MerTK by ONO-7475(0.1μM)effectively hindered csEV-mediated proliferation and migration of VSMCs in ex vivo mouse aorta injury model.Based on these results,we propose an essential role for csEVs in proliferation and migration of VSMCs and highlight the feasibility of dual AXL/MerTK inhibitors in the treatment of vascular diseases. | Young Joo Lee Miso Park Hyun Young Kim Jin-Ki Kim Won-Ki Kim Sung Chul Lim Keon Wook Kang | 2023 | Acta Pharmacologica Sinica2023，44，5： | 0 |
