1Search for the QCD critical point with fluctuations of conserved quantities in relativistic heavy-ion collisions at RHIC: an overview显示文摘Fluctuations of conserved quantities, such as baryon, electric charge, and strangeness number, are sensitive observables in relativistic heavy-ion collisions to probe the QCD phase transition and search for the QCD critical point. In this paper, we review the experimental measurements of the cumulants(up to fourth order) of event-byevent net-proton(proxy for net-baryon), net-charge and netkaon(proxy for net-strangeness) multiplicity distributions Au+Au collisions at sNN^(1/2) 7:7; 11:5; 14:5; 19:6; 27;39; 62:4; 200 Ge V from the first phase of beam energy scan program at the relativistic heavy-ion collider(RHIC). We also summarize the data analysis methods of suppressing the volume fluctuations, auto-correlations, and the unified description of efficiency correction and error estimation.Based on theoretical and model calculations, we will discuss the characteristic signatures of critical point as well as backgrounds for the fluctuation observables in heavy-ion collisions. The physics implications and the future secondphase of the beam energy scan(2019–2020) at RHIC will also be discussed.Xiaofeng Luo Nu XU 2017Nuclear Science and Techniques2017,28,8:19
2Circular RNAs and human glioma显示文摘As a newly discovered type of RNA, circular RNAs(circRNAs) are widespread throughout the eukaryotic genome. The expression of circRNAs is regulated by both cis-elements and trans-factors, and the expression pattern of circRNAs is cell type-and diseasespecific. Similar to other types of non-coding RNAs, functions of circRNAs are also versatile. CircRNAs have been reported previously to function as microRNA(miRNA) sponges, protein sponges, coding RNAs or scaffolds for protein complexes.Recently, several circRNAs have been reported to play important roles in human malignancies, including glioma. Here, we reviewed several reports related to circRNAs and glioma, as well as the potential diagnostic and therapeutic applications of circRNAs in brain cancer. In general, some circRNAs, such as circSMARCA5 and circCFH, are found to be expressed in a gliomaspecific pattern, these circRNAs may be used as tumor biomarkers. In addition, some circRNAs have been found to play oncogenic roles in glioma(e.g., circNFIX and circNT5E), whereas others have been reported to function as tumor suppressors(e.g.,circFBXW7 and circSHPRH). Furthermore, circRNA is a good tool for protein expression because of its higher stability compared to linear RNAs. Thus, circRNAs may also be an ideal choice for gene/protein delivery in future brain cancer therapies. There are some challenges in circRNA research in glioma and other diseases. Research related to circRNAs in glioma is comparatively new and many mysteries remain to be solved.Jinglei Liu Kun Zhao Nunu Huang Nu Zhang 2019Cancer Biology & Medicine2019,16,1:16

4Portal hypertensive colopathy is associated with portal hypertension severity in cirrhotic patients显示文摘AIM:To assess the prevalence of portal hypertension (PH) related colorectal lesions in liver transplant candidates, and to evaluate its association with the severity of PH.METHODS: Between October 2004 and December 2005, colonoscopy was performed in 92 cirrhotic liver transplant candidates. We described the lesions resulting from colorectal PH and their association with the grade of PH in 77 patients who underwent measurement of hepatic venous pressure gradient (HVPG).RESULTS: Mean age was 55 years and 80.7% of patients were men. The main etiology of cirrhosis was alcoholism (45.5%). Portal hypertensive colopathy (PHC) was found in 23.9%, colonic varices in 7.6% and polyps in 38% of patients (adenomatous type 65.2%). One asymptomatic patient had a well-differentiated adenocarcinoma. The manifestations of colorectal PH were not associated with the etiology of liver disease or with the Child-Pugh grade. Ninety percent of patients with colopathy presented with gastroesopha-geal varices (GEV), and 27.5% of patients with GEV presented with colopathy (P=0.12). A relationship between higher values of HVPG and presence of col-opathy was observed (19.9±6.2 mmHg vs 16.8±5.4 mmHg, P=0.045), but not with the grade of col-opathy (P=0.13). Preneoplastic polyps and neoplasm (P=0.02) and spontaneous bacterial peritonitis (P=0.006) were more prevalent in patients with colopathy. We did not observe any association between previous β-blocker therapy and the presence of colorectal portal hypertensive vasculopathy.CONCLUSION: PHC is common in cirrhotic liver trans-plant candidates and is associated with higher portal pressure.Antonio Diaz-Sanchez Oscar Nuez-Martinez Cecilia Gonzalez-Asanza Ana Matilla Beatriz Merino Diego Rincon Inmaculada Beceiro Maria Vega Catalina Magdalena Salcedo Rafael Baares Gerardo Clemente 2009World Journal of Gastroenterology2009,15,38:6

7Adaptive contourlet-wavelet iterative shrinkage/thresholding for remote sensing image restoration显示文摘In this paper, we present an adaptive two-step contourlet-wavelet iterative shrinkage/thresholding(TcwIST) algorithm for remote sensing image restoration. This algorithm can be used to deal with various linear inverse problems(LIPs), including image deconvolution and reconstruction. This algorithm is a new version of the famous two-step iterative shrinkage/thresholding(TwIST) algorithm. First, we use the split Bregman Rudin-Osher-Fatemi(ROF) model, based on a sparse dictionary, to decompose the image into cartoon and texture parts, which are represented by wavelet and contourlet, respectively. Second, we use an adaptive method to estimate the regularization parameter and the shrinkage threshold. Finally, we use a linear search method to find a step length and a fast method to accelerate convergence. Results show that our method can achieve a signal-to-noise ratio improvement(ISNR) for image restoration and high convergence speed.Nu WEN Shi-zhi YANG Cheng-jie ZHU Sheng-cheng CUI 2014Journal of Zhejiang University-Science C(Computers and Electronics)2014,15,8:5
8Gallstone ileus:One-stage surgery in a patient with intermittent obstruction显示文摘Gallstone ileus, an uncommon complication of cholelithiasis, is described as a mechanical intestinal obstruction due to impaction of one or more large gallstones within the gastrointestinal tract. The clinical presentation is variable, depending on the site of obstruction, manifested as acute, intermittent or chronic episodes. A 51-year-old female patient was referred to our hospital with 3 events of intestinal obstruction during the previous 7 d. At admission, there were clinical signs of intestinal obstruction; abdominal film demonstrated dilated bowel loops, air-fluid levels and a vague image of a stone in the inferior left quadrant. Once stabilized, a laparotomy was performed. Surgical findings were distention of the jejunum and ileum proximal to a palpable stone in the ileum as well as gallstones and a cholecystoduodenal fistula in the gallbladder. An enterolithotomy, repair of the cholecystoduodenal fistula and cholecystectomy were performed. The postoperative course was uneventful. There is no uniform surgical procedure for this disease. When the patient is too ill or when biliary surgery is not advisable, an enterolithotomy is the best option. The one-stage procedure should be the offered to adequately stabilized patients when local and general conditions, such as good cardiorespiratory and metabolic reserve permit a more prolonged surgical procedure.Carlos M Nuo-Guzmán José Arróniz-Jáuregui Pável A Moreno-Pérez édgar A Chávez-Solís Nereida Esparza-Arias Cuauhtémoc I Hernández-González 2010World Journal of Gastrointestinal Surgery2010,2,5:5
9Conceptual design of the HIRFL-CSR external-target experiment显示文摘One of the main purposes of heavy-ion collisions over a wide range of beam energy is to study the bulk properties of strong interaction matter and understand the Quantum Chromo Dynamics(QCD)phase diagram,which carries wealth of information of the phase transition and the possibly existing critical point of the strongly interacting system[1].Such system exists as hadron gases at lower temperature and low baryon density.By increasing the temperature or density,the boundary of the hadrons disappears and the confined quarksLiMing Lu Hart Yi ZhiGang Xiao Ming Shao Song Zhang GuoQing Xiao Nu Xu 2017Science China(Physics,Mechanics & Astronomy)2017,60,1:3
10在培养基和食料中添加铅和镉对轮虫种群动态的影响(英文)显示文摘由于工业活动的影响 ,墨西哥水体环境中的重金属浓度在上升。浮游动物 ,尤其是轮虫类 ,由于对环境变化十分敏感而且是淡水中的常见组成部分 ,因此被广泛用于生态毒理试验以确定水质标准。在不同的胁迫途径下 (如通过培养基或食料 ) ,重金属的毒性是不同的。在本研究中 ,通过在轮虫Brachionusrubens的培养基和食料中添加重金属这两种途径 ,我们评估了镉和铅的效应。对于这两种重金属 ,均采用将轮虫置于含 0 5×10 6个 /ml绿藻的培养基中或每天喂食经 5倍于LC50 值的金属处理 (1,2和 4h)的绿藻。对于在培养基中添加镉 ,使用了三个毒性水平 (0 1,0 2和 0 4mg/L) ,铅的浓度分别为 0 0 0 5 ,0 0 10和 0 0 15mg/L。基于LC50的数据 ,B .rubens对铅的敏感性要比镉高 2 4倍。镉浓度为 0 4mg/L时 ,培养基中加入镉造成B .rubens的生长趋缓。而喂食经不同时间处理的绿藻后 ,轮虫的密度随着食料在重金属中处理时间的延长而减小。培养基中或食料中添加铅时 ,轮虫种群生长的的趋势与在镉处理下的情况类似。随着培养基中重金属浓度的增加 ,每天种群增长率 (r值 )会减小。在培养基和食料处理两种不同途径下 ,r值会在 0 33(对照 )到 0 0 2d-1(经重金属处理 )S.S.S.SARMA Hilda Fabiola NU'EZ-CRUZ S.

13The black pottery coating of longshan times from Taosi Site显示文摘Taosi is an archaeological site in Xiangfen county, Shanxi province. It is considered as a capital city site with the rudiment of an early country in Longshan Times. In this work, the black pottery coating was found on the surface of black and grey pottery of Longshan times and confirmed by scientific studies for the first time. It filled in the blank of pottery coating study in this time period at the Yellow River Valley, as well as supplied a new study method of 'black skin pottery' besides the carburization craft. In addition, according to the archaeological materials, we inferred that the wares with this pottery coating might be only used by the nobility at that time.LU XiaoKe LI WeiDong LUO HongJie HE Nu LI XinWei 2011Science China(Technological Sciences)2011,54,7:2
