1Angiogenic markers endoglin and vascular endothelial growth factor in gastroenteropancreatic neuroendocrine tumors显示文摘AIM:To investigate the expression and potential prognostic role of vascular endothelial growth factor(VEGF) and endoglin in gastroenteropancreatic neuroendocrine tumors(GEP-NETs) . METHODS:Microvessel density(MVD) in GEP-NETs was evaluated using endoglin and CD31 immunohistochemistry.In addition,tissue levels of endoglin and VEGF were determined in homogenates by ELISA. RESULTS:Endoglin was highly expressed on tumor endothelial cells.CD31 MVD in GEP-NETs was significantly higher compared to endoglin MVD(P<0.01) .Two-tofour-fold higher tissue levels of endoglin and VEGF were seen in tumors compared to associated normal tissue. This increased endoglin tissue expression in tumors was significantly related to tumor size(P<0.01) ,presence of metastases(P=0.04) ,and a more advanced tumor stage(P=0.02) ,whereas expression of VEGF was not. CONCLUSION:We suggest that endoglin is a potential marker to indicate and predict metastases,which might be useful in the post-resection therapeutic approach of patients with GEP-NETs.Patricia Kuiper Lukas JAC Hawinkels Eveline SM de Jonge-Muller Izk Biemond Cornelis BHW Lamers Hein W Verspaget 2011World Journal of Gastroenterology2011,17,2:4
2The human olfactory system in two proteinopathies: Alzheimer’s and Parkinson’s diseases显示文摘Alzheimer’s and Parkinson’s diseases are the most prevalent neurodegenerative disorders.Their etiologies are idiopathic,and treatments are symptomatic and orientated towards cognitive or motor deficits.Neuropathologically,both are proteinopathies with pathological aggregates(plaques of amyloid-β peptide and neurofibrillary tangles of tau protein in Alzheimer’s disease,and Lewy bodies mostly composed of α-synuclein in Parkinson’s disease).These deposits appear in the nervous system in a predictable and accumulative sequence with six neuropathological stages.Both disorders present a long prodromal period,characterized by preclinical signs including hyposmia.Interestingly,the olfactory system,particularly the anterior olfactory nucleus,is initially and preferentially affected by the pathology.Cerebral atrophy revealed by magnetic resonance imaging must be complemented by histological analyses to ascertain whether neuronal and/or glial loss or neuropil remodeling are responsible for volumetric changes.It has been proposed that these proteinopathies could act in a prion-like manner in which a misfolded protein would be able to force native proteins into pathogenic folding(seeding),which then propagates through neurons and glia(spreading).Existing data have been examined to establish why some neuronal populations are vulnerable while others are resistant to pathology and to what extent glia prevent and/or facilitate proteinopathy spreading.Connectomic approaches reveal a number of hubs in the olfactory system(anterior olfactory nucleus,olfactory entorhinal cortex and cortical amygdala)that are key interconnectors with the main hubs(the entorhinal–hippocampal–cortical and amygdala–dorsal motor vagal nucleus)of network dysfunction in Alzheimer’s and Parkinson’s diseases.Isabel Ubeda-Bañon Daniel Saiz-Sanchez Alicia Flores-Cuadrado Ernesto Rioja-Corroto Melania Gonzalez-Rodriguez Sandra Villar-Conde Veronica Astillero-Lopez Juan Pablo Cabello-de la Rosa Maria Jose Gallardo-Alcañiz Julia Vaamonde-Gamo Fernanda Relea-Calatayud Lucia Gonzalez-Lopez Alicia Mohedano-Moriano Alberto Rabano Alino Martinez-Marcos 2020Translational Neurodegeneration2020,9,2:4
3RE_(6)Co_(2)Ga(RE=Ho,Dy or Gd)低温磁制冷材料的一级相变和二级相变显示文摘具有正交Ho_(6)Co_(2)Ga型晶体结构的富稀土金属间化合物因其具备独特的磁性能而被关注,但它们的磁有序、磁相变类型以及磁热性能尚未见系统报道.本文通过对RE_(6)Co_(2)Ga化合物中的稀土元素类型的调控,实现了材料相变类型从反铁磁(AF)到顺磁(PM)的变磁调控为铁磁(FM)到顺磁(PM)的转变.此外,通过实验观察结合密度泛函理论(DFT)计算证明了Gd_(6)Co_(2)Ga的基态为铁磁态.利用磁热效应的场依赖性关系结合Banerjee准则的判断标准研究表明,Ho_(6)Co_(2)Ga和Dy_(6)Co_(2)Ga同时具备二级相变和一级相变特征,而在Gd_(6)Co_(2)Ga中只存在二级相变.在0-5 T的磁场变化下,Ho_(6)Co_(2)Ga和Gd_(6)Co_(2)Ga的磁熵变分别在26和75 K附近达到最大值10.1和9.1J kg^(-1)K^(-1),而这两个温度分别接近于H_(2)液化和N_(2)液化温度.优异的磁热性能使得RE_(6)Co_(2)Ga体系在低温磁制冷领域具有潜在的应用前景.郭丹 Luis M.Moreno-Ramírez Carlos Romero-Muñiz 张义坤 Jia-Yan Law Victorino Franco 王江 任忠鸣 2021Science China Materials2021,64,11:2
4Long-term follow-up study of gastroduodenal lesions after radioembolization of hepatic tumors显示文摘AIM:To evaluate the long-term natural history of the gastroduodenal lesions secondary to extrahepatic embolization with Ytrium 90(90 Y) spheres.METHODS:From September 2003 to January 2012,379 procedures of liver radioembolization(RE) using resin microspheres loaded with 90 Y were performed in our center.We have retrospectively compiled the data from 379 RE procedures performed in our center.We report a comprehensive clinical,analytical,endoscopic and histologic long-term follow-up of a series of patients who developed gastroduodenal lesions after the treatment.RESULTS:Six patients(1.5%) developed gastrointestinal symptoms and had gastrointestinal lesions as shown by upper endoscopy in the next 12 wk after RE.The mean time between RE and the appearance of symptoms was 5 wk.Only one patient required endoscopic and surgical treatment.The incidence of gastrointestinal ulcerations was 3.75%(3/80) when only planar images were used for the pre-treatment evaluation.It was reduced to 1%(3/299) when singlephoton emission computed tomography(SPECT) images were also performed.The symptoms that lasted for a longer time were nausea and vomiting,until 25 mo after the treatment.CONCLUSION:All patients were free from severe symptoms at the end of follow-up.The routine use of SPECT has decreased the incidence of gastrointestinal lesions due to unintended deployment of 90 Y particles.Iago Rodríguez-Lago Cristina Carretero Maite Herráiz José C Subtil Maite Betés Macarena Rodríguez-Fraile Jesús J Sola José I Bilbao Miguel Muoz-Navas Bruno Sangro 2013World Journal of Gastroenterology2013,19,19:2

7Observation of the Crab Nebula with LHAASO-KM2A−a performance study显示文摘A sub-array of the Large High Altitude Air Shower Observatory(LHAASO),KM2A is mainly designed to observe a large fraction of the northern sky to hunt for γ-ray sources at energies above 10 TeV.Even though the detector construction is still underway,half of the KM2A array has been operating stably since the end of 2019.In this paper,we present the KM2A data analysis pipeline and the first observation of the Crab Nebula,a standard candle in very high energy γ-ray astronomy.We detect γ-ray signals from the Crab Nebula in both energy ranges of 10-100 TeV and>100 TeV with high significance,by analyzing the KM2A data of 136 live days between December 2019 and May 2020.With the observations,we test the detector performance,including angular resolution,pointing accuracy and cosmic-ray background rejection power.The energy spectrum of the Crab Nebula in the energy range 10-250 TeV fits well with a single power-law function dN/dE=(1.13±0.05stat±0.08sys)×10^(-14).(E/20 TeV)-309±0.06stat±0.02syscm^(-2) s^(-1) TeV^(-1).It is consistent with previous measurements by other experiments.This opens a new window of γ-ray astronomy above 0.1 PeV through which new ultrahigh-energy γ-ray phenomena,such as cosmic PeVatrons,might be discovered.F.Aharonian Q.An Axikegu L.X.Bai Y.X.Bai Y.W.Bao D.Bastieri X.J.Bi Y.J.Bi H.Cai J.T.Cai Z.Cao J.Chang J.F.Chang X.C.Chang B.M.Chen J.Chen L.Chen M.J.Chen M.L.Chen Q.H.Chen S.H.Chen S.Z.Chen T.L.Chen X.L.Chen Y.Chen N.Cheng Y.D.Cheng S.W.Cui X.H.Cui Y.D.Cui B.Z.Dai H.L.Dai Z.G.Dai D.della Volpe B.D'Ettorre Piazzoli X.J.Dong J.H.Fan Y.Z.Fan Z.X.Fan J.Fang K.Fang C.F.Feng L.Feng S.H.Feng Y.L.Feng B.Gao C.D.Gao Q.Gao W.Gao M.M.Ge L.S.Geng G.H.Gong Q.B.Gou M.H.Gu J.G.Guo X.L.Guo Y.Q.Guo Y.Y.Guo Y.A.Han H.H.He H.N.He J.C.He S.L.He X.B.He Y.He M.Heller Y.K.Hor C.Hou X.Hou H.B.Hu S.Hu S.C.Hu X.J.Hu D.H.Huang Q.L.Huang W.H.Huang X.T.Huang Z.C.Huang F.Ji X.L.Ji H.Y.Jia K.Jiang Z.J.Jiang C.Jin D.Kuleshov K.Levochkin B.B.Li C.Li F.Li H.B.Li H.C.Li H.Y.Li J.Li K.Li W.L.Li X.Li X.R.Li Y.Li Y.Z.Li Z.Li E.W.Liang Y.F.Liang S.J.Lin B.Liu C.Liu D.Liu H.Liu H.D.Liu J.Liu J.L.Liu J.S.Liu J.Y.Liu M.Y.Liu R.Y.Liu S.M.Liu W.Liu Y.N.Liu Z.X.Liu W.J.Long R.Lu H.K.Lv B.Q.Ma L.L.Ma X.H.Ma J.R.Mao A.Masood W.Mitthumsiri T.Montaruli Y.C.Nan B.Y.Pang P.Pattarakijwanich Z.Y.Pei M.Y.Qi D.Ruffolo V.Rulev A.Sáiz L.Shao O.Shchegolev X.D.Sheng J.R.Shi H.C.Song Yu.V.Stenkin V.Stepanov Q.N.Sun X.N.Sun Z.B.Sun P.H.T.Tam Z.B.Tang W.W.Tian B.D.Wang C.Wang H.Wang H.G.Wang J.C.Wang J.S.Wang L.P.Wang L.Y.Wang R.N.Wang W.Wang X.G.Wang X.J.Wang X.Y.Wang Y.D.Wang Y.J.Wang Y.P.Wang Z.Wang Z.H.Wang Z.X.Wang D.M.Wei J.J.Wei Y.J.Wei T.Wen C.Y.Wu H.R.Wu S.Wu W.X.Wu X.F.Wu S.Q.Xi J.Xia J.J.Xia G.M.Xiang G.Xiao H.B.Xiao G.G.Xin Y.L.Xin Y.Xing D.L.Xu R.X.Xu L.Xue D.H.Yan C.W.Yang F.F.Yang J.Y.Yang L.L.Yang M.J.Yang R.Z.Yang S.B.Yang Y.H.Yao Z.G.Yao Y.M.Ye L.Q.Yin N.Yin X.H.You Z.Y.You Y.H.Yu Q.Yuan H.D.Zeng T.X.Zeng W.Zeng Z.K.Zeng M.Zha X.X.Zhai B.B.Zhang H.M.Zhang H.Y.Zhang J.L.Zhang J.W.Zhang L.Zhang L.X.Zhang P.F.Zhang P.P.Zhang R.Zhang S.R.Zhang S.S.Zhang X.Zhang X.P.Zhang Y.Zhang Y.F.Zhang Y.L.Zhang B.Zhao J.Zhao L.Zhao L.Z.Zhao S.P.Zhao F.Zheng Y.Zheng B.Zhou H.Zhou J.N.Zhou P.Zhou R.Zhou X.X.Zhou C.G.Zhu F.R.Zhu H.Zhu K.J.Zhu X.Zuo 2021Chinese Physics C2021,45,2:2
