1长白山原始阔叶红松林土壤有机质组分小尺度空间异质性显示文摘土壤有机质(SOM)对于维持生态系统生产力具有非常重要的意义,有机质的组成、空间分布和空间关联性是影响和控制诸多生态系统过程的重要因素。应用地统计学方法,对长白山原始阔叶红松林局部尺度内0—20 cm土壤有机质与活性有机质的空间异质性进行了研究,并通过交叉半方差分析探讨了二者之间的相关性。研究结果表明:(1)总体上来说,土壤有机碳(SOC)、全氮(TN)、颗粒态有机碳(POC)和颗粒态有机氮(PON)空间异质性较小;而土壤微生物量碳(MBC)、微生物量氮(MBN)和表层(0—10 cm)溶解性有机碳(DOC)的空间异质性较大;(2)SOC、TN、MBC、DOC、POC和PON随着深度的增加空间自相关性增加;而溶解性有机氮(DON)的空间自相关性随深度的增加变化不大;(3)SOC与TN在表层和下层(10—20 cm)均存在空间上的正相关关系;(4)SOC、TN在表层和下层分别与MBC、MBN、DOC、DON和POC呈空间上的正相关性,但是与PON之间的空间相关关系较差;(5)不同土层深度的土壤活性有机质之间的相关关系存在差异。在表层,除POC,PON外,其余土壤活性有机质组分在空间上两两相关;但是随着土壤深度的增加,活性有机质变量之间在空间上两两相关。研究结果表明土壤有机质组分在长白山原始阔叶红松林小尺度内存在不同空间异质性和空间关联性,这为人们更好的理解森林生态系统功能(如土壤养分循环)提供了重要的理论依据。景莎 田静 M.

33GSps超高速ADC系统设计解决方案显示文摘包含千兆采样率ADC的系统设计会遇到许多复杂情况。面临的主要挑战包括时钟驱动、模拟输入级和高速数字接口。本文探讨了如何才能克服这些挑战,并给出了在千兆赫兹的速度下进行系统优化的方法。在讨论中.时钟设计、差分输入驱动器的设计、数字接口和布局考虑都是十分复杂的问题。本文中的参考设计将采用ADC083000/B3000。Paul McCormack 2007电子设计技术 EDN CHINA2007,14,6:6
4西罗奠司治疗淋巴管平滑肌瘤病的有效性和安全性显示文摘背景和目的:在女性中,淋巴管平滑肌瘤病(LAM)是一种持续进展的肺部囊性病变,该病和哺乳动物的雷帕霉素靶蛋白(mTOR)信号通路不恰当的激活相关,该通路可调节细胞的生长和淋巴管的生成。西罗莫司(也称雷帕霉素)可抑制mTOR,并且在包括LAM患者的Ⅰ~Ⅱ期试验中已显示出治疗前景。McCormack FX Inoue Y MOSSJ 牟向东 章巍 2011中华结核和呼吸杂志2011,34,12:4
5Fatty liver disease,an emerging etiology of hepatocellular carcinoma in Argentina显示文摘AIM To investigate any changing trends in the etiologies of hepatocellular carcinoma(HCC) in Argentina during the last years. METHODS A longitudinal cohort study was conducted by 14 regional hospitals starting in 2009 through 2016. All adult patients with newly diagnosed HCC either with pathology or imaging criteria were included. Patients were classified as presenting non-alcoholic fatty liver disease(NAFLD) either by histology or clinically, provided that all other etiologies of liver disease were ruled out, fatty liver was present on abdominal ultrasound and alcohol consumption was excluded. Complete follow-up was assessed in all included subjects since the date of HCC diagnosis until death or last medical visit.RESULTS A total of 708 consecutive adults with HCC were included. Six out of 14 hospitals were liver transplant centers(n = 484). The prevalence of diabetes mellitus was 27.7%. Overall, HCV was the main cause of liver disease related with HCC(37%) including cirrhotic and non-cirrhotic patients, followed by alcoholic liver disease 20.8%, NAFLD 11.4%, cryptogenic 9.6%, HBV 5.4% infection, cholestatic disease and autoimmune hepatitis 2.2%, and other causes 9.9%. A 6-fold increase in the percentage corresponding to NAFLDHCC was detected when the starting year, i.e., 2009 was compared to the last one, i.e., 2015(4.3% vs 25.6%; P < 0.0001). Accordingly, a higher prevalence of diabetes mellitus was present in NAFLD-HCC group 61.7% when compared to other than NAFLD-HCC 23.3%(P < 0.0001). Lower median AFP values at HCC diagnosis were observed between NAFLD-HCC and non-NAFLD groups(6.6 ng/m L vs 26 ng/m L; P = 0.02). Neither NAFLD nor other HCC etiologies were associated with higher mortality.CONCLUSION The growing incidence of NAFLD-HCC documented in the United States and Europe is also observed in Argentina, a confirmation with important Public Health implications.Federico Pinero Josefina Pages Sebastián Marciano Nora Fernández Jorge Silva Margarita Anders Alina Zerega Ezequiel Ridruejo Beatriz Ameigeiras Claudia D’Amico Luis Gaite Carla Bermúdez Manuel Cobos Carlos Rosales Gustavo Romero Lucas McCormack Virginia Reggiardo Luis Colombato Adrián Gadano Marcelo Silva 2018World Journal of Hepatology2018,10,1:4

8Rates and impact of hepatitis on human immunodeficiency virus infection in a large African cohort显示文摘AIM:To determine the rates and impact of hepatitis B virus(HBV) and hepatitis C virus(HCV) infections on response to long-term highly active antiretroviral therapy(HAART) in a large human immunodeficiency virus(HIV) population in Nigeria.METHODS:HBV and HCV as well as HIV infections are endemic in sub Saharan Africa.This was a retrospective cohort study of 19 408 adults who were recruited between June 2004 and December 2010 in the AIDS Prevention Initiative in Nigeria in Nigeria programme at Jos University Teaching Hospital.Serological assays,including HBV surface antigen(HBsAg) and hepatitis C antibody were used to categorise hepatitis status of the patients.HBsAg was determined using enzyme immunoassay(EIA)(Monolisa HBsAg Ultra3;Bio-Rad).HCV antibody was tested using third generation EIA(DIA.PRO Diagnostic,Bioprobes srl,Milan,Italy).HIV RNA levels were measured using Roche COBAS Amplicor HIV-1 monitor test version 1.5(Roche Diagnostics,GmbH,Mannheim,Germany) with a detection limit of 400 copies/mL.Flow cytometry was used to determine CD4+ cell count(Partec,GmbH Munster,Germany).Comparison of categorical and continuous variables were achieved using Pearson's χ 2 and Kruskal Wallis tests respectively,on MedCalc for Windows,version 9.5.0.0(MedCalc Software,Mariakerke,Belgium).RESULTS:With an overall hepatitis screening rate of over 90% for each virus;HBV,HCV and HBV/HCV were detected in 3162(17.8%),1983(11.3%) and 453(2.5%) HIV infected adults respectively.The rate of liver disease was low,but highest among HIV monoinfected patients(29,0.11%),followed by HBV coinfected patients(15,0.08%).Patients with HBV coinfection and triple infection had higher log 10 HIV RNA loads(HBV:4.6 copies/mL vs HIV only:4.5 copies/mL,P<0.0001) and more severe immune suppression(HBV:645,55.4%;HBV/HCV:97,56.7%) prior to initiation of HAART compared to HIV mono-infected patients(1852,48.6%)(P<0.0001).Of 3025 patients who were 4.4 years on HAART and whose CD4 cell counts results at baseline and end of follow up were available for analyses,CD4 increase was significantly lower in those with HBV co-infection(HBV:144 cells/mm3 ;HBV/HCV:105 cells/mm3) than in those with HCV co-infection(165 cells/mm3) and HIV mono-infection(150 cells/mm3)(P=0.0008).CONCLUSION:High rates of HBV and HCV infections were found in this HIV cohort.CD4 recovery was significantly diminished in patients with HBV co-infection.Nimzing Gwamzhi Ladep Patricia Aladi Agaba Oche Agbaji Auwal Muazu Placid Ugoagwu Godwin Imade Graham Cooke Sheena McCormack Simon David Taylor-Robinson John Idoko Phyllis Kanki 2013World Journal of Gastroenterology2013,19,10:3
