1AFLP初析小豆栽培和野生变种(Vigna angularis var.angularis and var.nipponensis)间演化与地理分布关系显示文摘利用 12对AFLP引物 ,以饭豆标准品系M 0 0作对照 ,对来自中国、日本、韩国、尼泊尔、印度、不丹的 14 6份小豆栽培种 (Vignaangularisvar.angularis)和野生种 (Vignaangularisvar.nipponensis)种质的基因组DNA进行扩增 ,得到 313条多态性带。据AFLP多态性数据绘制的聚类图 ,可区分其中的 14 3份种质 ,表明小豆物种 (Vi gnaangularis)存在足够的遗传多样性 ,可用于资源材料的准确鉴别与分类。鉴于此 ,采用新开发的利用AFLP数据揭示核苷多样性的Innan’s进化树分析方法 ,进一步将 14 6份小豆资源分成 7个明显不同的地理演化群 ,即中国栽培种、日本栽培种、日本综合群 韩国栽培种、中国台湾野生种、中国野生种、尼泊尔 不丹栽培种和喜马拉雅野生种演化群。就上述地理演化群的遗传多样性、地理分布以及野生种与栽培种之间可能的演化关系进行了分析 ,初步认为栽培小豆至少应当有 4个不同类型的野生祖先和 3个不同的地理起源。宗绪晓 Duancan Vaughan Norihiko Tomooka Akito Kaga 王新望 关建平 王述民 2003中国农业科学2003,36,4:19
2AFLP分析小豆种(Vigna angularis)内遗传多样性显示文摘利用 12对AFLP引物 ,对来自于世界 6个国家的 14 6份小豆 (Vignaangularis)栽培变种 (var.angularis)和野生变种 (var.nipponensis)种质的基因组DNA进行扩增 ,得到 5 80条清晰的显带 ,其中 313(5 3 93% )条呈多态性 ,平均每对AFLP引物得到 2 6 0 8条多态性带 ;平均遗传距离 0 35 ,变异幅度为 0 0 0~ 0 87。利用AFLP多态性数据进行的Jaccard’s遗传距离聚类分析绘制的聚类图 ,可将其中的 14 3份种质相互区分开 ,并将其中的 14 5份小豆资源划分成 8个明显不同组群 ,显示小豆种内存在足够的遗传多样性用于资源材料的准确鉴别与分类。 8个组群的遗传多样性表现出十分明显的地域相关性 ,以及遗传类型趋同性。通过各组群内和组群间的遗传距离比较 ,发现世界小豆主要栽培资源以及日本野生、半野生资源中蓄积的遗传多样性较匮乏 ,而储藏于中国野生小豆资源、喜马拉雅地区栽培和野生资源中的遗传多样性较丰富。宗绪晓 D Vaughan A Kaga N Tomooka 王新望 关建平 王述民 2003作物学报2003,29,4:18
3One fifth of hospitalizations for peptic ulcer-related bleeding are potentially preventable显示文摘AIM:To calculate the proportion of potentially preventable hospitalizations due to peptic ulcer disease(PUD),erosive gastritis(EG)or duodenitis(ED).METHODS:Retrospective cohort study using ICD-10codes to identify all patients with upper gastrointestinal hemorrhage secondary to endoscopically proven PUD,EG or ED during the period from March 2007 to October 2010 in three major metropolitan hospitals in Melbourne,Australia.Patients were divided into'high risk'(those who would benefit from gastroprotection)and'not high risk'groups as defined by established guidelines.Mean Rockall score,transfusion requirement,length of stay,rebleeding rates,need for surgery and in-hospital mortality was compared between'high risk'and'not high risk'groups.Within the'high risk'group,those on gastroprotection and those with no gastroprotection were also compared.RESULTS:Five hundred and seven patients were included for analysis of which 174 were classified as high risk.Median values of complete Rockall Score(5vs 4,P=0.002)and length of stay(5 d vs 4 d,P=0.04)were higher in the high risk group but in-hospital mortality was lower(0.6%vs 3.9%,P=0.03).130out of the 174 patients in the high risk group were not taking recommended gastroprotective therapy prior to hospitalization.Past history of PUD(OR=3.7,P=0.006)and clopidogrel use(OR=3.2,P=0.007)significantly predicted prescription of gastroprotective therapy.Using proton pump inhibitor protection rates of 50%-85%from published studies,an estimation of13%to 22%of the total number of the hospitalizations due to PUD or EG/ED related bleeding may have been preventable.CONCLUSION:Up to one fifth of all hospitalizations for bleeding secondary to PUD or EG/ED are potentially preventable.Ray Boyapati Sim Ye Ong Bei Ye Anuk Kruavit Nora Lee Rhys Vaughan Sanjay Nurkar Peter Gibson Mayur Garg 2014World Journal of Gastroenterology2014,20,30:8
4Review of High Voltage Direct Current Cables显示文摘Increased renewable energy integration and international power trades have led to the construction and development of new HVDC transmission systems.HVDC cables,in particular,play an important role in undersea power transmission and offshore renewable energy integration having lower losses and higher reliability.In this paper,the current commercial feasibility of HVDC cables and the development of different types of HVDC cables and accessories are reviewed.The non-uniform electric field distribution caused by the applied voltage,temperature dependent conductivity,and space charge accumulation is briefly discussed.Current research in HVDC cable for higher operation voltage level and larger power capacity is also reviewed with specific focus on the methodologies of space charge suppression for XLPE extruded cables.George Chen Miao Hao Zhiqiang Xu Alun Vaughan Junzheng Cao Haitian Wang 2015CSEE Journal of Power and Energy Systems2015,1,2:5

6Novel drug-delivery approaches to the blood-brain barrier显示文摘The blood-brain barrier(BBB) maintains homeostasis by blocking toxic molecules from the circulation, but drugs are blocked at the same time. When the dose is increased to enhance the drug concentration in the central nervous system, there are side-effects on peripheral organs. In recent years, genetic therapeutic agents and small molecules have been used in various strategies to penetrate the BBB while minimizing the damage to systemic organs. In this review, we describe several representative methods to circumvent or cross the BBB, including chemical and physical strategies.Xiaoqing Wang Xiaowen Yu William Vaughan Mingyuan Liu Yangtai Guan 2015Neuroscience Bulletin2015,31,2:2

13Idiopathic non-hypertrophic pyloric stenosis in an infant successfully treated via endoscopic approach显示文摘Non-peptic, nonhypertrophic pyloric stenosis has rarely been reported in pediatric literature. Endoscopic pyloric balloon dilation has been shown to be a safe procedure in treating gastric outlet obstruction in older children and adults. Partial gastric outlet obstruction (GOO) was diagnosed in an infant by history and confirmed by anupper gastrointestinal series (UGI). Abdominal ultrasonography and computed tomography scan excluded idiopathic hypertrophic pyloric stenosis, abdominal tumors, gastrointestinal and hepato-biliary-pancreatic anomalies. Endoscopic findings showed a pinhole-sized pylorus and did not indicate peptic ulcer disease, Helicobacter pylori infection, antral web, or eviden-ce of allergic and inflammatory bowel diseases. Three sessions of a step-wise endoscopic pyloric balloon dilation were conducted under general anesthesia and a fluoroscopy at two week intervals using catheter balloons (Boston Scientific Microvasive?, MA, USA) of increasing diameters. Repeat UGI after the first session revealed normal gastrointestinal transit and no intestinalobstruction. The patient tolerated solid food without any gastrointestinal symptoms since the first session. The endoscope was able to be passed through the pylorus after the last session. Although the etiology of GOO in this infant is unclear (proposed mechanisms are herein discussed), endoscopic pyloric balloon dilation was a safe procedure for treating this young infant with non-peptic, non-hypertrophic pyloric stenosis and should be considered as an initial approach before pyloroplasty in such presentations.Wikrom Karnsakul Mary L Cannon Stacey Gillespie Richard Vaughan 2010World Journal of Gastrointestinal Endoscopy2010,2,12:2
