1Clinically detected gastroenteropancreatic neuroendocrine tumors are on the rise: Epidemiological changes in Germany显示文摘AIM:To study the epidemiologic changes of gastroenteropancreatic neuroendocrine tumors(GEP-NET)in Germany,we analyzed two time periods 1976-1988 and1998-2006.METHODS:We evaluated epidemiological data of GEP-NET from the former East German National Cancer Registry(DDR Krebsregister,1976-1988)and its successor,the Joint Cancer Registry(GKR,1998-2006),which was founded after German reunification.Due to a particularly substantial database the epidemiological data from the federal states of Mecklenburg-Western Pomerania,Saxony,Brandenburg and Thuringia,covering a population of more than 10.8 million people,were analyzed.Survival probabilities were calculated using life table analysis.In addition,GEP-NET patients were evaluated for one or more second(non-GEP-NET)primary malignancies.RESULTS:A total of 2821 GEP neuroendocrine neoplasms were identified in the two registries.The overall incidence increased significantly between 1976 and2006 from 0.31(per 100.000 inhabitants per year)to2.27 for men and from 0.57 to 2.38 for women.In the later period studied(2004-2006),the small intestine was the most common site.Neuroendocrine(NE)neoplasms of the small intestine showed the largest absolute increase in incidence,while rectal NE neoplasms exhibited the greatest relative increase.Only the incidence of appendiceal NET in women showed little change between 1976 and 2006.Overall survival of patients varied for sex,tumor site and the two periods studied but improved significantly over time.Interestingly,about 20%of the GEP-NET patients developed one or more second malignancies.Their most common location was the gastrointestinal tract.GEP-NET patients without second malignancies fared better than those with one or more of them.CONCLUSION:The number of detected GEP-NET increased about 5-fold in Germany between 1976 and2006.At the same time,their anatomic distribution changed,and the survival of GEP-NET patients improved significantly.Second malignancies are common and influence the overall survival of GEP-NET patients.Thus,GEP-NET warrant our attention as well as intensive research on their tumorigenesis.Hans Scherübl Brigitte Streller Roland Stabenow Hermann Herbst Michael Hopfner Christoph Schwertner Joachim Steinberg Jan Eick Wanda Ring Krishna Tiwari Soren M Zappe 2013World Journal of Gastroenterology2013,19,47:16
2云南省临沧市临翔区农村居民HIV检测服务利用和感染风险认知情况调查显示文摘目的了解云南临沧市临翔区农村居民对艾滋病病毒(HIV)检测的实际利用情况,以及对感染HIV风险的认知情况,为提高HIV检测服务利用提供基础信息。方法通过随机抽样方法,抽取大众人群进行面对面调查,对调查对象的一般人口统计学特征、HIV检测利用和自身感染风险等信息进行统计分析。结果 2007、2008、2009年,分别有1 153、909和899人参与。结果发现当地大众人群对HIV检测利用低于15%;超过60%的人愿意在医疗机构进行检测;超过50%的人没有意识到自身有感染HIV的风险,缺乏风险意识是影响他们不能主动进行检测的主要原因。结论当地农村居民对自身感染HIV的风险意识不足,影响了他们对HIV检测服务的利用,需对此制订干预措施来提高HIV检测率。刘霞 Michael Hermann 邓邦炎 2011中国艾滋病性病2011,17,2:5

4Comparative transcriptome analyses shed light on carotenoid production and plastid development in melon fruit显示文摘Carotenoids,such asβ-carotene,accumulate in chromoplasts of various fleshy fruits,awarding them with colors,aromas,and nutrients.The Orange(CmOr)gene controlsβ-carotene accumulation in melon fruit by posttranslationally enhancing carotenogenesis and repressingβ-carotene turnover in chromoplasts.Carotenoid isomerase(CRTISO)isomerizes yellow prolycopene into red lycopene,a prerequisite for further metabolism intoβ-carotene.We comparatively analyzed the developing fruit transcriptomes of orange-colored melon and its two isogenic EMS-induced mutants,low-β(Cmor)and yofi(Cmcrtiso).The Cmor mutation in low-βcaused a major transcriptomic change in the mature fruit.In contrast,the Cmcrtiso mutation in yofi significantly changed the transcriptome only in early fruit developmental stages.These findings indicate that melon fruit transcriptome is primarily altered by changes in carotenoid metabolic flux and plastid conversion,but minimally by carotenoid composition in the ripe fruit.Clustering of the differentially expressed genes into functional groups revealed an association between fruit carotenoid metabolic flux with the maintenance of the photosynthetic apparatus in fruit chloroplasts.Moreover,large numbers of thylakoid localized photosynthetic genes were differentially expressed in low-β.CmOR family proteins were found to physically interact with light-harvesting chlorophyll a–b binding proteins,suggesting a new role of CmOR for chloroplast maintenance in melon fruit.This study brings more insights into the cellular and metabolic processes associated with fruit carotenoid accumulation in melon fruit and reveals a new maintenance mechanism of the photosynthetic apparatus for plastid development.Noam Chayut Hui Yuan Yuval Saar Yi Zheng Tianhu Sun Xuesong Zhou Anna Hermanns Elad Oren Adi Faigenboim Maixia Hui Zhangjun Fei Michael Mazourek Joseph Burger Yaakov Tadmor Li Li 2021Horticulture Research2021,8,1:3

8Concept and proof for an all-silicon MEMS micro speaker utilizing air chambers显示文摘MEMS-based micro speakers are attractive candidates as sound transducers for smart devices,particularly wearables and hearables.For such devices,high sound pressure levels,low harmonic distortion and low power consumption are required for industrial,consumer and medical applications.The ability to integrate with microelectronic circuitry,as well as scalable batch production to enable low unit costs,are the key factors benchmarking a technology.The Nanoscopic Electrostatic Drive based,novel micro speaker concept presented in this work essentially comprises inplane,electrostatic bending actuators,and uses the chip volume rather than the its surface for sound generation.We describe the principle,design,fabrication,and first characterization results.Various design options and governing equations are given and discussed.In a standard acoustical test setup(ear simulator),a MEMS micro speaker generated a sound pressure level of 69 dB at 500 Hz with a total harmonic distortion of 4.4%,thus proving the concept.Further potential on sound pressure as well as linearity improvement is outlined.We expect that the described methods can be used to enhance and design other MEMS devices and foster modeling and simulation approaches.Bert Kaiser Sergiu Langa Lutz Ehrig Michael Stolz Hermann Schenk Holger Conrad Harald Schenk Klaus Schimmanz David Schuffenhauer 2019Microsystems & Nanoengineering2019,5,1:2

15Challenges in the Detection and Attribution of Northern Hemisphere Surface Temperature Trends Since 1850显示文摘Since 2007,the Intergovernmental Panel on Climate Change(IPCC)has heavily relied on the comparison between global climate model hindcasts and global surface temperature(ST)estimates for concluding that post-1950s global warming is mostly human-caused.In Connolly et al.,we cautioned that this approach to the detection and attribution of climate change was highly dependent on the choice of Total Solar Irradiance(TSI)and ST data sets.We compiled 16 TSI and five ST data sets and found by altering the choice of TSI or ST,one could(prematurely)conclude anything from the warming being“mostly human-caused”to“mostly natural.”Richardson and Benestad suggested our analysis was“erroneous”and“flawed”because we did not use a multilinear regression.They argued that applying a multilinear regression to one of the five ST series re-affirmed the IPCC's attribution statement.They also objected that many of the published TSI data sets were out-of-date.However,here we show that when applying multilinear regression analysis to an expanded and updated data set of 27 TSI series,the original conclusions of Connolly et al.are confirmed for all five ST data sets.Therefore,it is still unclear whether the observed warming is mostly human-caused,mostly natural or some combination of both.Ronan Connolly Willie Soon Michael Connolly Sallie Baliunas Johan Berglund C.J.Butler Rodolfo Gustavo Cionco Ana G.Elias Valery M.Fedorov Hermann Harde Gregory W.Henry Douglas V.Hoyt Ole Humlum David R.Legates Nicola Scafetta Jan-Erik Solheim LászlóSzarka Víctor M.Velasco Herrera Hong Yan Weijia Zhang 2023Research in Astronomy and Astrophysics2023,23,10:1
