1Choledocholithiasis: Evolving standards for diagnosis and management显示文摘胆石病,导致外科的干预的最普通的医药条件之一,在美国影响成年人口的约 10 % 。胆总管石病与胆囊石头在大约病人的 10%-20% 发展,文学建议至少经历胆囊炎的病人的 3%-10% 将有胆总管(CBD ) 石头。CBD 石头可以外科手术前地, intraoperatively 或手术后地被发现多重形式为包括实验室测试,超声,计算断层摄影术扫描(CT ) ,和磁性的回声 cholangiopancreatography (MRCP ) 为胆总管石病估计病人是可得到的。Intraoperative 胆管造影术能习惯性地或有选择地在胆囊炎期间被使用诊断 CBD 石头。为 CBD 石头的最普通的干预是 ERCP。另外的通常使用的干预包括 intraoperative 胆汁管探索,任何一个 laparoscopic 或 open。经皮, transhepatic 石头移动胆汁的清理的另外的新奇技术被设计了。与这些技术灵巧的设备和有技能的专业人员的可获得性在机构之中变化。预定干预被临床的状况经常支配。Marilee L Freitas Robert L Bell Andrew J Duffy 2006World Journal of Gastroenterology2006,12,20:30
2Evolution of surgical skills training显示文摘外科的训练正在变化:100 年传统被法律、道德的担心为耐心的安全,工作小时限制,手术室时间的费用,和复杂并发症正在质问。训练的外科的模拟和技巧提供一个机会在在生活病人上尝试他们前在手术室环境外面教并且练习先进技巧。当使用真实仪器和录像设备操作在一个盒子训练员模仿了“织物”,模拟训练能向前是同样直的。更先进的、虚拟现实模拟器现在为普遍使用可得到、准备好了。早系统表明了他们的有效性和歧视的能力。更新的系统启用全面课程和完整的程序的模拟的开发。医药教育是的毕业生的认证委员会(ACGME ) 要求了训练和评估的新奇方法的发展。外科的组织正在打电话让方法保证技巧的维护,并且,进展 surgical 训练信任外科医生作为技术上能干。在他们的当前的形式的模拟器被表明了改进外科的居民的手术室表演。训练课程标准化的开发仍然是一个迫切、重要的议程,特别地为最小的侵略外科。一条创新、进步的途径,从航空的域借经验,能为外科的训练的下一个世纪提供基础,保证产品的质量。当技术发展,我们练习的方法将继续演变,到医生和病人的利益。Kurt E Roberts Robert L Bell Andrew J Duffy 2006World Journal of Gastroenterology2006,12,20:8
3Computer-based Creativity Enhanced Conceptual Design Model for Non-routine Design of Mechanical Systems显示文摘Computer-based conceptual design for routine design has made great strides, yet non-routine design has not been given due attention, and it is still poorly automated. Considering that the function-behavior-structure(FBS) model is widely used for modeling the conceptual design process, a computer-based creativity enhanced conceptual design model(CECD) for non-routine design of mechanical systems is presented. In the model, the leaf functions in the FBS model are decomposed into and represented with fine-grain basic operation actions(BOA), and the corresponding BOA set in the function domain is then constructed. Choosing building blocks from the database, and expressing their multiple functions with BOAs, the BOA set in the structure domain is formed. Through rule-based dynamic partition of the BOA set in the function domain, many variants of regenerated functional schemes are generated. For enhancing the capability to introduce new design variables into the conceptual design process, and dig out more innovative physical structure schemes, the indirect function-structure matching strategy based on reconstructing the combined structure schemes is adopted. By adjusting the tightness of the partition rules and the granularity of the divided BOA subsets, and making full use of the main function and secondary functions of each basic structure in the process of reconstructing of the physical structures, new design variables and variants are introduced into the physical structure scheme reconstructing process, and a great number of simpler physical structure schemes to accomplish the overall function organically are figured out. The creativity enhanced conceptual design model presented has a dominant capability in introducing new deign variables in function domain and digging out simpler physical structures to accomplish the overall function, therefore it can be utilized to solve non-routine conceptual design problem.LI Yutong WANG Yuxin DUFFY Alex H B 2014Chinese Journal of Mechanical Engineering2014,27,6:5

5磺酰脲除草剂与土壤的关系显示文摘自1975年杜邦公司George Levit博士发现磺酰脲类除草剂以来,已经成为一类主要的新颖除草剂,并促进化学除草技术的重大进步。目前世界范围内,共有8种磺酰脲除草剂已经商品化(表1),估计到九十年代中期会成倍增加,它们具有前所未有的除草活性,其使用量从千克/公顷惊人地下降到克/公顷。如今,甲黄隆每年用量为2~8克/公顷,使用200年也不过相当于过去传统除草剂一次使用量(1~4千克/公顷)。杀草谱广、用量低、对作物又有较大选择性,这些都是磺酰脲除草剂迅速成功的重要因素。同样重要的。E.

6Controversies in the treatment of gastroesophageal reflux and achalasia显示文摘胃的食道的倒流疾病(GERD ) 和弛缓不能的有效治疗为这二作为标准答案建立了最小的侵略外科的 laparoscopic 外科的巨大的成功与更低的病态和死亡调节,更短的医院停留,更快的康复,和不太手术后的疼痛。在 GERD 的处理的一争吵作为比较喜欢的处理在 laparoscopic 反倒流外科(LARS ) 附近演变让 Barrett 的食管和过程的潜力减少食管的腺癌的风险。GERD 也与呼吸症状,气喘和喉的损害被联系了,并且第二争吵推动全部或部分的 fundoplication 是否是为 GERD 的更适当的处理的讨论。在 GERD 的处理的一种新、有希望的选择是 endoluminal 治疗。这种新处理选择的三种类型将被讨论:送到更低的食道的括约肌的射频精力,在胃的食道的连接的一个机械障碍的创造,并且更低的食道的括约肌的直接内视镜的紧缩。Laparoscopic 外科为弛缓不能为 GERD 而且同样永久的痊愈作为很有效的治疗被讨论不仅。这评论为弛缓不能分析三种很重要的处理选择:药,灵魂膨胀,和外科的治疗。因为他们的短半衰期和可变吸收,在弛缓不能的处理的药同样唯一的真非侵略的选择由于穷人不象 LARS 一样有效食道的倒空。第二种处理选择,灵魂膨胀,包含拉长更低的食管并且是仍然为弛缓不能考虑了最有效的非外科的处理。最后,为弛缓不能的外科的治疗和有关这个 laparoscopic 处理的二主要争吵被讨论。第一包含肌切开术被扩大到到胃上的程度,并且第二使反倒流过程的必要性和类型担心在肌切开术以后阻止 GERD。LARS 和 laparoscopic Heller 肌切开术是同意了在之上作为为 GERD 和弛缓不能的外科疗法的标准答案分别地。在一位富有经验的 laparoscopic 外科医生的手里,两个是为有有至少 90% 耐心的满足的优秀主观、客观的长期的结果的病人的安全、有效的治疗。Kurt E Roberts Andrew J Duffy Robert L Bell 2006World Journal of Gastroenterology2006,12,20:4

12Modulation of tau phosphorylation by environmental copper显示文摘Background:The transition metal copper enhances amyloidβaggregation and neurotoxicity,and in models of concomitant amyloid and tau pathology,copper also promotes tau aggregation.Since it is not clear if the effects of environmental copper upon tau pathology are dependent on the presence of pathological amyloidβ,we tested the effects of copper overload and complexing in disease models which lack pathological amyloidβ.Methods:We used cell culture and transgenic murine models to test the effects of environmental copper on tau phosphorylation.We used oral zinc acetate as a copper lowering agent in mice and examined changes in blood and brain metals through inductively coupled plasma mass spectroscopy.Behavioral effects of copper lowering were assessed with Morris water maze and novel object recognition tasks.Changes in tau phosphorylation were examined by phosphorylation specific antibodies on Western blots.Results:In human neuroblastoma cells,excess copper promoted tau phosphorylation and a copper complexing agent,tetrathiomolybdate,attenuated tau phosphorylation.In a transgenic mouse model expressing wild type human tau,copper-lowering by oral zinc suppressed plasma and brain levels of copper,and resulted in a marked attenuation of tau phosphorylation.No significant changes in behavior were observed with copper lowering,but a trend to improved recognition of the novel object was observed in zinc acetate treated mice.Conclusions:We propose that reduction of brain copper by blocking uptake of copper from the diet may be a viable strategy for modulating tau pathology in Alzheimer’s disease.The potential benefits of this approach are tempered by the absence of a behavioral benefit and by the health risks of excessive lowering of copper.Kellen Voss Christopher Harris Martina Ralle Megan Duffy Charles Murchison Joseph F Quinn 2014Translational Neurodegeneration2014,3,1:3
13Spatiotemporal event detection: a review显示文摘The advancements of sensing technologies,including remote sensing,in situ sensing,social sensing,and health sensing,have tremendously improved our capability to observe and record natural and social phenomena,such as natural disasters,presidential elections,and infectious diseases.The observations have provided an unprecedented opportunity to better understand and respond to the spatiotemporal dynamics of the environment,urban settings,health and disease propagation,business decisions,and crisis and crime.Spatiotemporal event detection serves as a gateway to enable a better understanding by detecting events that represent the abnormal status of relevant phenomena.This paper reviews the literature for different sensing capabilities,spatiotemporal event extraction methods,and categories of applications for the detected events.The novelty of this review is to revisit the definition and requirements of event detection and to layout the overall workflow(from sensing and event extraction methods to the operations and decision-supporting processes based on the extracted events)as an agenda for future event detection research.Guidance is presented on the current challenges to this research agenda,and future directions are discussed for conducting spatiotemporal event detection in the era of big data,advanced sensing,and artificial intelligence.Manzhu Yu Myra Bambacus Guido Cervone Keith Clarke Daniel Duffy Qunying Huang Jing Li Wenwen Li Zhenlong Li Qian Liu Bernd Resch Jingchao Yang Chaowei Yang 2020International Journal of Digital Earth2020,13,12:2
