1卫星遥感结合地面观测估算非均匀地表区域能量通量显示文摘卫星遥感在研究非均匀陆面上地-气间能量和水循环过程时有其独到的作用。文中介绍了一种利用LANDSATTM资料进行非均匀陆面上区域能量平衡研究的参数化方案。并以夏季和深秋两个景的TM资料为个例,结合“黑河实验”(HEIFE)期间的地面观测资料分析了实验区非均匀陆面上地表特征参数及能量平衡各分量的区域分布及季节差异,同时将所得的结果与地面观测的“真值”作了比较,所得的这些结果是基本可信的。这种方法仍然处于发展的初始阶段,对此也进行了讨论。马耀明 王介民 Massimo Menenti Wim Bastiaanssen 1999气象学报1999,57,2:62
2Challenges in diagnosing mesenteric ischemia显示文摘Early identification of acute mesenteric ischemia (AMI) is challenging. The wide variability in clinical presentation challenges providers to make an early accurate diagnosis. Despite major diagnostic and treatment advances over the past decades, mortality remains high. Arterial embolus and superior mesenteric artery thrombosis are common causes of AMI. Non-occlusive causes are less common, but vasculitis may be important, especially in younger people. Because of the unclear clinical presentation and non-specific laboratory findings, low clinical suspicion may lead to loss of valuable time. During this diagnostic delay, progression of ischemia to transmural bowel infarction with peritonitis and septicemia may further worsen patient outcomes. Several diagnostic modalities are used to assess possible AMI. Multi-detector row computed tomographic angiography is the current gold standard. Although computed tomographic angiography leads to an accurate diagnosis in many cases, early detection is a persistent problem. Because early diagnosis is vital to commence treatment, new diagnostic strategies are needed. A non-invasive simple biochemical test would be ideal to increase clinical suspicion of AMI and would improve patient selection for radiographic evaluation. Thus, AMI could be diagnosed earlier with follow-up computed tomographic angiography or high spatial magnetic resonance imaging. Experimental in vitro and in vivo studies show promise for alpha glutathione S transferase and intestinal fatty acid binding protein as markers for AMI. Future research must confirm the clinical utility of these biochemical markers in the diagnosis of mesenteric ischemia.Teun C van den Heijkant Bart AC Aerts Joep A Teijink Wim A Buurman Misha DP Luyer 2013World Journal of Gastroenterology2013,19,9:31
3发展生物燃料乙醇对我国区域农业发展的影响分析显示文摘本文利用“中国农业可持续发展决策支持系统”分析了不同燃料乙醇发展政策可能对我国农产品价格、整体和各区域农业生产及净产值等的影响。研究结果表明:燃料乙醇发展将显著提高能源作物的农产品价格,对农业发展和农民增收将起到积极的促进作用,但对稻谷和小麦等粮食安全有一些负面影响;燃料乙醇发展对不同区域及不同农户的影响有较大差异;多数地区的农业部门都将从中受益,获益的大小主要取决于各地区在种植能源作物上的比较优势。研究也指出,未来的重点应放在非粮作物以及第二代生物燃料乙醇技术上(即用纤维素生产乙醇),并且应该提高在这些方面的科研投资水平。黄季焜 仇焕广 Michiel Keyzer Erika Meng Wim van Veen 2009经济学(季刊)2009,8,1:30

5Non-invasive assessment of barrier integrity and function of the human gut显示文摘Over the past decades evidence has been accumulating that intestinal barrier integrity loss plays a key role in the development and perpetuation of a variety of disease states including inflammatory bowel disease and celiac disease,and is a key player in the onset of sepsis and multiple organ failure in situations of intestinal hypoperfusion,including trauma and major surgery.Insight into gut barrier integrity and function loss is important to improve our knowledge on disease etiology and pathophysiology and contributes to early detection and/or secondary prevention of disease.A variety of tests have been developed to assess intestinal epithelial cell damage,intestinal tight junction status and consequences of intestinal barrier integrity loss,i.e.increased intestinal permeability.This review discusses currently available methods for evaluating loss of human intestinal barrier integrity and function.Joep Grootjans Geertje Thuijls Froukje Verdam Joep PM Derikx Kaatje Lenaerts Wim A Buurman 2010World Journal of Gastrointestinal Surgery2010,2,3:18
6五年级小学生数学问题提出能力和观念的调查研究显示文摘近几年来,数学问题提出日益受到学者们的重视,然而中国小学生数学问题提出能力与观念之间关系的研究不是很深入,特别是数学问题提出能力的测量缺乏有效的评价指标.因此,构建一个有效的数学问题提出能力的评价体系,并在此基础上探究小学生数学问题提出能力和观念之间的关系就显得尤为重要.对辽宁省117名五年级小学生数学问题提出能力和观念的情况,及其二者之间的关系进行调查.调查结果表明:首先,大部分学生都能够提出正确的数学问题,而提出创新性的,复杂程度高的数学问题存在困难.同时,学生对学好数学问题提出,缺乏一定的信心.其次,学生的数学问题提出能力和观念之间存在较高的相关性.陈丽敏 景敏 Verschaffel Lieven Van Dooren Wim 2013数学教育学报2013,22,2:17
7Role of autophagy in the pathophysiology of nonalcoholic fatty liver disease:A controversial issue显示文摘Autophagy is a mechanism involved in cellular homeostasis under basal and stressed conditions delivering cytoplasmic content to the lysosomes for degradation to macronutrients.The potential role of autophagy in disease is increasingly recognised and investigated in the last decade.Nowadays it is commonly accepted that autophagy plays a role in the hepatic lipid metabolism.Hence,dysfunction of autophagy may be an underlying cause of non-alcoholic fatty liver disease.However,controversy of the exact role of autophagy in the lipid metabolism exists:some publications report a lipolytic function of autophagy,whereas others claim a lipogenic function.This review aims to give an update of the present knowledge on autophagy in the hepatic lipid metabolism,hepatic insulin resistance,steatohepatitis and hepatic fibrogenesis.Wilhelmus J Kwanten Wim Martinet Peter P Michielsen Sven M Francque 2014World Journal of Gastroenterology2014,20,23:17

9Diagnosis of deep vein thrombosis,and prevention of deep vein thrombosis recurrence and the post-thrombotic syndrome in the primary care medicine setting anno 2014显示文摘The requirement for a safe diagnostic strategy of deep vein thrombosis(DVT) should be based on an overall objective post incidence of venous thromboembolism(VTE) of less than 1% during 3 mo fol low-up. Compression ultrasonography(CUS) of the leg veins has a negative predictive value(NPV) of 97%-98% indicating the need of repeated CUS testing within one week. A negative ELISA VIDAS safely excludes DVT and VTE with a NPV between 99% and 100% at a low clinical score of zero. The combination of low clinical score and a less sensitive D-dimer test(Simplify) is not sensitive enough to exclude DVT and VTE in routine daily practice. From prospective clinical research studies it may be concluded that complete recanalization within 3-6 mo and no reflux is associated with a low or no risk of PTS obviating the need of MECS 6 mo after DVT. Partial and complete recanalization after 6 to more than 12 mo is usually complicated by reflux due to valve destruction and symptomatic PTS. Reflux seems to be a main determinant for PTS and DVT recurrence, the latter as a main contributing factor in worsening PTS. This hypothesis is supported by the relation between the persistent residual vein thrombosis(RVT = partial recanalization) and the risk of VTE recurrence in prospective studies. Absence of RVT at 3 mo postDVT and no reflux is predicted to be associated with no recurrence of DVT(1.2%) during follow-up obviating the need of wearing medical elastic stockings and anticoagulation at 6 mo post-DVT. The presence or absence of RVT but with reflux at or after 6 mo postDVT is associated with both symptomatic PTS and an increased risk of VTE recurrence in about one third in the post-DVT period after regular discontinuation of anticoagulant treatment. To test this hypothesis we designed a prospective DVT and postthrombotic syndrome(PTS) Bridging the Gap Study by addressing at least four unanswered questions in the treatment ofDVT and PTS.Which DVT patient has a clear indication for long-term compression stocking therapy to prevent PTS after the initial anticoagulant treatment in the acute phase of DVT?Is 6 mo the appropriate point in time to determine candidates at risk to develop DVT recurrence and PTS?Which high risk symptomatic PTS patients need extended anticoagulant treatment?Jan Jacques Michiels Janneke Maria Michiels Wim Moossdorff Mildred Lao Hanny Maasland Gualtiero Palareti 2015World Journal of Critical Care Medicine2015,4,1:14

11海上风电场降低成本前景分析显示文摘目前,海上风电场的经济效益比陆上风电场稍逊一筹。为加强海上风电场的竞争力,迫切需要大幅降低成本。海上风电场大约70%的成本来自于最初的投资成本,包括风机、海上地基、内部和外部电网安装和连接等等。文章分析了海上和陆上风电的技术发展和成本要素,并参考了海上油、汽开发以及高压海底输电的工程信息,肯定海上风电场的成本是可以降低的。分析了影响成本降低的主要因素;提出在不同的增长设想下,到2020年海上风电场的投资成本将降低25%~39%。Martin Junginger Andre Faaij Wim C.Turkenburg 吕斌 2007上海电力2007,20,4:11
12Life and death at the mucosal-luminal interface: New perspectives on human intestinal ischemia-reperfusion显示文摘Intestinal ischemia is a frequently observed phenomenon. Morbidity and mortality rates are extraordinarily high and did not improve over the past decades. This is in part attributable to limited knowledge on the pathophysiology of intestinal ischemia-reperfusion(IR) in man, the paucity in preventive and/or therapeutic options and the lack of early diagnostic markers for intestinal ischemia. To improve our knowledge and solve clinically important questions regarding intestinal IR, we developed a human experimental intestinal IR model. With this model, we were able to gain insight into the mechanisms that allow the human gut to withstand short periods of IR without the development of severe inflammatory responses. The purpose of this review is to overview the most relevant recent advances in our understanding of the pathophysiology of human intestinal IR, as well as the(potential) future clinical implications.Joep Grootjans Kaatje Lenaerts Wim A Buurman Cornelis HC Dejong Joep PM Derikx 2016World Journal of Gastroenterology2016,22,9:11

14Extent of surgery in cancer of the colon:Is more better?显示文摘Since the introduction of total mesorectal excision as the standard approach in mid and low rectal cancer,the incidence of local recurrence has sharply declined.Similar attention to surgical technique in colon cancer(CC) has resulted in the concept of complete mesocolic excision(CME),which consists of complete removal of the intact mesentery and high ligation of the vascular supply at its origin.Although renewed attention to meticulous surgical technique certainly has its merits,routine implementation of CME is currently unfounded.Firstly,in contrast to rectal cancer,local recurrence originating from an incompletely removed mesenteryis rare in CC and usually a manifestation of systemic disease.Secondly,although CME may increase nodal counts and therefore staging accuracy,this is unlikely to affect survival since the observed relationship between nodal counts and outcome in CC is most probably not causal but confounded by a range of clinical variables.Thirdly,several lines of evidence suggest that metastasis to locoregional nodes occurs early and is a stochastic rather than a stepwise phenomenon in CC,in essence reflecting the tumor-host-metastasis relationship.Unsurprisingly,therefore,comparative studies in CC as well as in other digestive cancers have failed to demonstrate any survival benefit associated with extensive,additional or extra-mesenteric lymphadenectomy.Finally,routine implementation of CME may cause patient harm by longer operating times,major vascular damage and autonomic nerve injury.Therefore,data from randomized trials reporting relevant endpoints are required before CME can be recommended as a standard approach in CC surgery.Wouter Willaert Wim Ceelen 2015World Journal of Gastroenterology2015,21,1:11
15Controlling postoperative ileus by vagal activation显示文摘Postoperative ileus is a frequently occurring surgical complication, leading to increased morbidity and hospital stay. Abdominal surgical interventions are known to result in a protracted cessation of bowel movement. Activation of inhibitory neural pathways by nociceptive stimuli leads to an inhibition of propulsive activity, which resolves shortly after closure of the abdomen. The subsequent formation of an inflammatory infiltrate in the muscular layers of the intestine results in a more prolonged phase of ileus. Over the last decade, clinical strategies focusing on reduction of surgical stress and promoting postoperative recovery have improved the course of postoperative ileus. Additionally, recent experimental evidence implicated antiinflammatory interventions, such as vagal stimulation, as potential targets to treat postoperative ileus and reduce the period of intestinal hypomotility. Activation of nicotinic receptors on inflammatory cells by vagal input attenuates inflammation and promotes gastrointestinal motility in experimental models of ileus. A novel physiologicalintervention to activate this neuroimmune pathway is enteral administration of lipid-rich nutrition. Perioperative administration of lipid-rich nutrition reduced manipulation-induced local inflammation of the intestine and accelerated recovery of bowel movement. The application of safe and easy to use antiinflammatory interventions, together with the current multimodal approach, could reduce postoperative ileus to an absolute minimum and shorten hospital stay.Tim Lubbers Wim Buurman Misha Luyer 2010World Journal of Gastroenterology2010,16,14:10
16Challenges and prospects for consumer acceptance of cultured meat显示文摘Consumer acceptance of cultured meat is expected to depend on a wide diversity of determinants ranging from technologyrelated perceptions to product-specific expectations, and including wider contextual factors like media coverage, public involvement, and trust in science, policy and society. This paper discusses the case of cultured meat against this multitude of possible determinants shaping future consumer acceptance or rejection. The paper also presents insights from a primary exploratory study performed in April 2013 with consumers from Flanders(Belgium)(n=180). The concept of cultured meat was only known(unaided) by 13% of the study participants. After receiving basic information about what cultured meat is, participants expressed favorable expectations about the concept. Only 9% rejected the idea of trying cultured meat, while two thirds hesitated and about quarter indicated to be willing to try it. The provision of additional information about the environmental benefits of cultured meat compared to traditional meat resulted in 43% of the participants indicating to be willing to try this novel food, while another 51% indicated to be ‘maybe' willing to do so. Price and sensory expectations emerged as major obstacles. Consumers eating mostly vegetarian meals were less convinced that cultured meat might be healthy, suggesting that vegetarians may not be the ideal primary target group for this novel meat substitute. Although exploratory rather than conclusive, the findings generally underscore doubts among consumers about trying this product when it would become available, and therefore also the challenge for cultured meat to mimic traditional meat in terms of sensory quality at an affordable price in order to become acceptable for future consumers.Wim Verbeke Pierre Sans Ellen J Van Loo 2015Journal of Integrative Agriculture2015,14,2:10
17Diagnostic yield of small bowel capsule endoscopy depends on the small bowel transit time显示文摘AIM:To investigate whether the small bowel transit time(SBTT)influences the diagnostic yield of capsule endoscopy(CE).METHODS:Six hundred and ninety-one consecutive CE procedures collected in a database were analyzed.SBTT and CE findings were recorded.A running mean for the SBTT was calculated and correlated to the diagnostic yield with a Spearman's correlation test.Subgroup analyses were performed for the various indications for the procedure.RESULTS:There was a positive correlation between the diagnostic yield and SBTT(Spearman's rho 0.58,P <0.01).Positive correlations between diagnostic yield and SBTT were found for the indication obscure gastrointestinal bleeding(r=0.54,P<0.01),for polyposis and carcinoid combined(r=0.56,P<0.01)and for the other indications(r=0.90,P<0.01),but not for suspected Crohn's disease(r=-0.40).CONCLUSION:The diagnostic yield in small bowel capsule endoscopy is positively correlated with the small bowel transit time.This is true for all indications except for suspected Crohn's disease.Jessie Westerhof Jan J Koornstra Reinier A Hoedemaker Wim J Sluiter Jan H Kleibeuker Rinse K Weersma 2012World Journal of Gastroenterology2012,18,13:10
18TraitMill:禾谷类作物高产基因发掘的引擎(英文)显示文摘转基因技术是研究植物发育的有效的途径。比利时的作物设计公司(CropDesign)成功研制出称为TraitMill的技术平台,TraitMill平台不仅是一个能够大规模开展转基因和植株评价的高通量的技术平台,而且还是一个在植物表型上鉴定基因和基因组合的非常有用的工具。无论是在理想的植株生长条件下,还是在不同非生物逆境或营养胁迫条件下,利用TraitMill平台每年可成功地鉴定成百个不同的“启动子—基因”组合。基于对水稻生长发育的特别设计和高精度的测量方法改造,TraitMill平台已经全面应用于水稻转基因及其性状的评价。迄今为止,TraitMill平台是唯一一个将转基因技术和植株性状自动化评价系统相结合的技术平台。显然,应用于改良禾谷类作物产量基因的鉴定,TraitMill平台具有独特的优势。Christophe Reuzeau Jan Pen Valérie Frankard Joris de Wolf Rindert Peerbolte Willem Broekaert Wim van Camp 方宣钧(推荐人) 2005分子植物育种2005,3,5:10
19Non-invasive markers of gut wall integrity in health and disease显示文摘The intestinal mucosa is responsible for the absorption of nutrients from the lumen and for the separation of the potentially toxic luminal content(external environment) from the host(internal environment).Disruption of this delicate balance at the mucosal interface is the basis for numerous(intestinal) diseases.Experimental animal studies have shown that gut wall integrity loss is involved in the development of various inflammatory syndromes,including post-operative or post-traumatic systemic inflammatory response syndrome,sepsis,and multiple organ failure.Assessment of gut wall integrity in clinical practice is still a challenge,as it is difficult to evaluate the condition of the gut non-invasively with currently available diagnostic tools.Moreover,non-invasive,rapid diagnostic means to assess intestinal condition are needed to evaluate the effects of treatment of intestinal disorders.This review provides a survey of non-invasive tests and newly identified markers that can be used to assess gut wall integrity.Joep PM Derikx Misha DP Luyer Erik Heineman Wim A Buurman 2010World Journal of Gastroenterology2010,16,42:9
