2High-resolution multimodal flexible coherent Raman endoscope显示文摘Coherent Raman scattering microscopy is a fast,label-free,and chemically specific imaging technique that shows high potential for future in vivo optical histology.However,the imaging depth in tissues is limited to the sub-millimeter range because of absorption and scattering.Realization of coherent Raman imaging using a fiber endoscope system is a crucial step towards imaging deep inside living tissues and providing information that is inaccessible with current microscopy tools.Until now,the development of coherent Raman endoscopy has been hampered by several issues,mainly related to the fiber delivery of the excitation pulses and signal collection.Here,we present a flexible,compact,coherent Raman,and multimodal nonlinear endoscope(4.2mm outer diameter,71mm rigid length)based on a resonantly scanned hollow-core Kagomé-lattice double-clad fiber.The fiber design enables distortion-less,background-free delivery of femtosecond excitation pulses and back-collection of nonlinear signals through the same fiber.Sub-micrometer spatial resolution over a large field of view is obtained by combination of a miniature objective lens with a silica microsphere lens inserted into the fiber core.We demonstrate high-resolution,high-contrast coherent anti-Stokes Raman scattering,and second harmonic generation endoscopic imaging of biological tissues over a field of view of 320μm at a rate of 0.8 frames per second.These results pave the way for intraoperative label-free imaging applied to real-time histopathology diagnosis and surgery guidance.Alberto Lombardini Vasyl Mytskaniuk Siddharth Sivankutty Esben Ravn Andresen Xueqin Chen Jérôme Wenger Marc Fabert Nicolas Joly Frédéric Louradour Alexandre Kudlinski Hervé Rigneault 2018Light(Science & Applications)2018,7,1:6
3Inflammation and reactive oxygen species in cardiovascular disease显示文摘Reactive oxygen species(ROS)have long been proposed to be mediators of experimental cardiovascular pathology.There is also a wealth of data indicating that ROS are involved in clinical cardiovascular pathology.However,multiple clinical studies have shown little benefit from anti-oxidant treatments,whereas nearly all experimental studies have shown a marked effect of anti-oxidant therapy.One reason for this discrepancy is that ROS are produced through multiple different mechanisms of which some are clinically beneficial;thus,in a defined experimental system where predominately pathological ROS are generated does not mimic a clinical setting where there are likely to be multiple ROS generating systems producing beneficial and pathological ROS.Simple inhibition of ROS would not be expected to have the same result in these two situations;ergo,it is important to understand the molecular mechanism underlying the production of ROS so that clinical treatments can be tailored to target the pathological production of ROS.One such example of this in cardiovascular biology is tissue specific inflammation-mediated ROS generation.This and the following series of articles discuss the current understanding of the role of ROS in cardiovascular disease,specifically focusing on the molecular mechanisms of ROS generation and the actions of ROS within the cardiovascular system.Although there are still many areas with regard to the effects of ROS in the cardiovascular system that are not completely understood,there is a wealth of data suggesting that blocking pathological ROS production is likely to have beneficial clinical effects compared to traditional anti-oxidants.Bradley T Andresen 2010World Journal of Cardiology2010,2,12:5
4Active Thermal Control for Delaying Maintenance of Power Electronics Converters显示文摘Several studies have reported about power semiconductors and capacitors being the most sensitive components in power converters.The lifetime of these devices is associated with the mission profile and the resulting temperature profile.For preventing failures,it is of interest to estimate the Remaining Useful Lifetime(RUL)and several condition monitoring methods have been proposed for this purpose.Moreover,modular power converters consist of a high number of components and methods have been proposed to reduce the thermal stress and therefore extend the lifetime of a system with software,referred to as active thermal control.For power converters with limited accessibility,the RUL detected by the condition monitoring system may not fit to the scheduled maintenance of the system and devices may still have a significant RUL when their replacement is scheduled.Therefore,this work proposes to control the stress of the most deteriorated components in the system such that the failure probability of multiple building blocks is equalized when the next maintenance is scheduled.Moreover,this concept is proposed to extend the time to the next maintenance and reduce the number of maintenance instances without affecting the mean lifetime of the system.Markus Andresen Johannes Kuprat Vivek Raveendran Johannes Falck Marco Liserre 2018Chinese Journal of Electrical Engineering2018,4,3:4
5西方的“1968”:学生运动的起源、过程和后果显示文摘1968这一年在西方工业国的集体记忆里留下了各种的深刻烙印。对保守者来说,这是一个社会与政治价值观坍塌的开始;而对全球左派而言,它带来了社会与政治自由化。学生要求全面的民主,要求结束越南战争和更多的社会自由。'1968'年这一概念下集中了众多因素。美国和联邦德国学生运动的新左派尽管都经历了政治激进化和理论新建的过程,但是其影响力却体现在长期的、首先是新的生活方式之中。'1968'年发生的那些事件,造成了以社会地位的不同为背景的生活方式的个体化和集体化,但也并非其唯一的起因。价值观转变的冲动是青年整体的诉求,要求生活质量和自我决定权而不接受作为规范的工作纪律、道德纯洁和责任义务。尽管新的挑衅及交往战略在学生运动中做了尝试,普遍的个体化和民主化以此得以加速,但并非由此引发。它是1960年代以来西方工业国家的复杂的现代化过程的一部分。Knud Andresen 2012史林2012,,5:3
6Megacolon in adulthood after surgical treatment of Hirschsprung's disease in early childhood显示文摘Hirschsprung's disease (HD) is a disorder associated with congenital malformation of the enteric nervous system with segmental aganglionosis. Prevailing therapy includes a resection of the affected part of the bowel. However, patients often do not obtain complete functional improvement after surgical treatment. We present the case of a 25-year-old woman who had surgical treatment of HD in early childhood. After that procedure she had clinical features of constipation for years in the end,passing of stool once a week, requiring laxatives and enemas. We diagnosed an incomplete resection of the aganglionic bowel via rectal biopsy and resected the remaining aganglionic segment. Two months after surgery the patient's bowel function improved to a frequency of 1-4 stools per day. We conclude that regular follow-up is required to identify HD patients with persistent alterations of bowel function after surgery. In patients presenting with constipation, recognition of a remaining aganglionic segment or other alterations of the enteric nervous system should be aimed at in an early stage.Christoph R.Werner Gisela Stoltenburg-Didinger Henning Weidemann Christoph Benckert Marco Schmidtmann Ivo R.van der Voort Viola Andresen Burghard F.Klapp Peter Neuhaus Bertram Wiedenmann Hubert Mnnikes 2005World Journal of Gastroenterology2005,11,36:3
7Smart Transformer/Large Flexible Transformer显示文摘Solid-state transformer-based smart transformer(ST)can provide the dc connectivity and advanced services to improve the grid performance and to increase the penetration of the power electronics interfaced resources(e.g.,distributed generators and electric vehicle charging stations)in modern electricity distribution grids.Since the ST is a new and effective paradigm of the electricity grid evolution to well understand the ST,this paper systematically presents the basic architecture and the typical control schemes of the ST and then the advanced services that ST can provide to improve the electricity grids performances in terms of the power flow control,power quality improvement,active damping and active contribution to improve distribution grid resilience by means of enabling autonomous microgrids operation as well as launching a restoration procedure following a general blackout.Rongwu Zhu Markus Andresen Marius Langwasser Marco Liserre Joao Pecas Lopes Carlos Moreira Justino Rodrigues Mario Couto 2020CES Transactions on Electrical Machines and Systems2020,4,4:3
8Translational pain research: Evaluating analgesic effect in experimental visceral pain models显示文摘Deep visceral pain is frequent and presents major challenges in pain management, since its pathophysiology is still poorly understood. One way to optimize treatment of visceral pain is to improve knowledge of the mechanisms behind the pain and the mode of action of analgesic substances. This can be achieved through stand-ardized experimental human pain models. Experimental pain models in healthy volunteers are advantageous for evaluation of analgesic action, as this is often diff icult to assess in the clinic because of confounding factors such as sedation, nausea and general malaise. These pain models facilitate minimizing the gap between knowledge gained in animal and human clinical studies. Combining experimental pain studies and pharmacokinetic stud- ies can improve understanding of the pharmacokinetic-pharmacodynamic relationship of analgesics and, thus, provide valuable insight into optimal clinical treatment of visceral pain. To improve treatment of visceral pain, it is important to study the underlying mechanisms of pain and the action of analgesics used for its treatment. An experimental pain model activates different modalities and can be used to investigate the mechanism of action of different analgesics in detail. In combination with pharmacokinetic studies and objective assessment such as electroencephalography, new information re-garding a given drug substance and its effects can be obtained. Results from experimental human visceral pain research can bridge the gap in knowledge between animal studies and clinical condition in patients suffering from visceral pain, and thus constitute the missing link in translational pain research.Anne Estrup Olesen Trine Andresen Lona Louring Christrup Richard N Upton 2009World Journal of Gastroenterology2009,15,2:3

11Serotonin type 3 receptor subunit gene polymorphisms associated with psychosomatic symptoms in irritable bowel syndrome:A multicenter retrospective study显示文摘BACKGROUND Single-nucleotide polymorphisms(SNPs)of the serotonin type 3 receptor subunit(HTR3)genes have been associated with psychosomatic symptoms,but it is not clear whether these associations exist in irritable bowel syndrome(IBS).AIM To assess the association of HTR3 polymorphisms with depressive,anxiety,and somatization symptoms in individuals with IBS.METHODS In this retrospective study,623 participants with IBS were recruited from five specialty centers in Germany,Sweden,the United States,the United Kingdom,and Ireland.Depressive,anxiety,and somatization symptoms and sociodemographic characteristics were collected.Four functional SNPs—HTR3A c.-42C>T,HTR3B c.386A>C,HTR3C c.489C>A,and HTR3E c.*76G>A—were genotyped and analyzed using the dominant and recessive models.We also performed separate analyses for sex and IBS subtypes.SNP scores were calculated as the number of minor alleles of the SNPs above.The impact of HTR3C c.489C>A was tested by radioligand-binding and calcium influx assays.RESULTS Depressive and anxiety symptoms significantly worsened with increasing numbers of minor HTR3C c.489C>A alleles in the dominant model(F_(depressive)=7.475,P_(depressive)=0.006;F_(anxiety)=6.535,P_(anxiety)=0.011).A higher SNP score(range 0-6)was linked to a worsened depressive symptoms score(F=7.710,P-linear trend=0.006)in IBS.The potential relevance of the HTR3C SNP was corroborated,showing changes in the expression level of 5-HT3AC variant receptors.CONCLUSION We have provided the first evidence that HTR3C c.489C>A is involved in depressive and anxiety symptoms in individuals with IBS.The SNP score indicated that an increasing number of minor alleles is linked to the worsening of depressive symptoms in IBS.Sabrina Berens Yuanjun Dong Nikola Fritz Jutta Walstab Mauro D'Amato Tenghao Zheng Verena Wahl Felix Boekstegers Justo Lorenzo Bermejo Cristina Martinez Stefanie Schmitteckert Egbert Clevers Felicitas Engel Annika Gauss Wolfgang Herzog Robin Spiller Miriam Goebel-Stengel Hubert Mönnikes Viola Andresen Frieling Thomas Jutta Keller Christian Pehl Christoph Stein-Thöringer Gerard Clarke Timothy G Dinan Eamonn M Quigley Gregory Sayuk Magnus Simrén Jonas Tesarz Gudrun Rappold Lukas van Oudenhove Rainer Schaefert Beate Niesler 2022World Journal of Gastroenterology2022,28,21:2

13Sorption and phase distribution of ethanol and butanol blended gasoline vapours in the vadose zone after release显示文摘The sorption and phase distribution of 20% ethanol and butanol blended gasoline(E20 and B20) vapours have been examined in soils with varying soil organic matter(SOM) and water contents via laboratory microcosm experiments. The presence of 20% alcohol reduced the sorption of gasoline compounds by soil as well as the mass distribution of the compounds to soil solids. This effect was greater for ethanol than butanol. Compared with the sorption coefficient(Kd) of unblended gasoline compounds, the Kd of E20 gasoline compounds decreased by 54% for pentane, 54% for methylcyclopentane(MCP) and 63% for benzene, while the Kd of B20 gasoline compounds decreased by 39% for pentane, 38% for MCP and 49% for benzene. The retardation factor(R) of E20 gasoline compounds decreased by 53% for pentane, 53% for MCP and 48% for benzene, while the R of B20 gasoline compounds decreased by 39% for pentane, 37% for MCP and 38% for benzene. For all SOM and water contents tested, the Kd and R of all gasoline compounds were in the order of unblended gasoline > B20 > E20, indicating that the use of high ethanol volume in gasoline to combat climate change could put the groundwater at greater risk of contamination.Ejikeme Ugwoha John M.
