| 1 | Navigated liver surgery:State of the art and future perspectives显示文摘Background:In recent years,the development of digital imaging technology has had a significant influence in liver surgery.The ability to obtain a 3-dimensional(3D)visualization of the liver anatomy has provided surgery with virtual reality of simulation 3D computer models,3D printing models and more recently holograms and augmented reality(when virtual reality knowledge is superimposed onto reality).In addition,the utilization of real-time fluorescent imaging techniques based on indocyanine green(ICG)uptake allows clinicians to precisely delineate the liver anatomy and/or tumors within the parenchyma,applying the knowledge obtained preoperatively through digital imaging.The combination of both has transformed the abstract thinking until now based on 2D imaging into a 3D preoperative conception(virtual reality),enhanced with real-time visualization of the fluorescent liver structures,effectively facilitating intraoperative navigated liver surgery(augmented reality).Data sources:A literature search was performed from inception until January 2021 in MEDLINE(Pub Med),Embase,Cochrane library and database for systematic reviews(CDSR),Google Scholar,and National Institute for Health and Clinical Excellence(NICE)databases.Results:Fifty-one pertinent articles were retrieved and included.The different types of digital imaging technologies and the real-time navigated liver surgery were estimated and compared.Conclusions:ICG fluorescent imaging techniques can contribute essentially to the real-time definition of liver segments;as a result,precise hepatic resection can be guided by the presence of fluorescence.Furthermore,3D models can help essentially to further advancing of precision in hepatic surgery by permitting estimation of liver volume and functional liver remnant,delineation of resection lines along the liver segments and evaluation of tumor margins.In liver transplantation and especially in living donor liver transplantation(LDLT),3D printed models of the donor’s liver and models of the recipient’s hilar anatomy can contribute further to improving the results.In particular,pediatric LDLT abdominal cavity models can help to manage the largest challenge of this procedure,namely large-for-size syndrome. | Paschalis Gavriilidis Bjørn Edwin Egidijus Pelanis Ernest Hidalgo Nicola de’Angelis Riccardo Memeo Luca Aldrighetti Robert P Sutcliffe | 2022 | Hepatobiliary & Pancreatic Diseases International2022，21，3： | 6 |
| 2 | Survey on Simulation for Mobile Ad-Hoc Communication for Disaster Scenarios显示文摘活动特定的通讯是一个表明的答案在大规模灾难期间减轻基础结构失败的影响。在这域的一个很复杂的问题是在自然灾难期间支持决策和通讯的软件应用程序的设计确认。如此的灾难是 irreproducible,对规模在下面高度无法预言、不可能、这样广泛评价不能在 situ 被带。在这上下文,模拟向测试自然灾难回答的软件解决方案组成最好的途径。现在的调查考察活动性模型,特定的网络体系结构,路由协议和网络模拟器。我们的目的是借助于模拟关于他们的应用程序的表演评估为软件开发者提供指南。 | Erika Rosas Nicolas Hidalgo Veronica Gil-Costa Carolina Bonacic Mauricio Marin Hermes Senger Luciana Arantes CesarMarcondes Olivier Marin | 2016 | Journal of Computer Science & Technology2016，31，2： | 0 |
| 3 | Polyploidy in Cupressaceae:Discovery of a new naturally occurring tetraploid,Xanthocyparis vietnamensis显示文摘While polyploidy(whole-genome multiplication)is generally considered rare in extant gymnosperms(with the exception of Ephedra,Ephedraceae),the occurrence of sporadic polyploid individuals belonging to various genera in the conifer family Cupressaceae has been reported in the literature.In addition,recent studies have revealed that polyploidy is not uncommon in the genus Juniperus(Cupressaceae),with tetraploid and hexaploid individuals reported in individuals collected from wild populations.Given these findings,we undertook a comprehensive screening of ploidy levels in 32 species belonging to the four genera that are phylogenetically closest to Juniperus(i.e.,Callitropsis,Hesperocyparis,Xanthocyparis,and Cupressus),referred to as the CaHXCu complex.In addition,we also determined the ploidy level of two accessions in the poorly studied tetraploid,Fitzroya cupressoides.Using flow cytometry together with published chromosome counts to assign ploidy levels,we show that all species of the CaHXCu complex are diploid except Xanthocyparis vietnamensis,which is tetraploid,with a genome size of 44.60 pg/2 C.This study opens up new opportunities for studying the impact and consequences of polyploidy on the evolution and adaptation of species in Cupressaceae. | Perla Farhat Sonja Siljak-Yakovlev Oriane Hidalgo Keith Rushforth Jim ABartel Nicolas Valentin Ilia J.Leitch Robert P.Adams | 2022 | Journal of Systematics and Evolution2022，60，4： | 0 |
