2皮质下小血管病诊断的共识声明显示文摘血管性认知损害是用于描述一组涉及大血管和小血管的散发性和遗传性异质性疾病的诊断术语。皮质下小血管病可导致腔隙性梗死和进行性白质损害。被称为宾斯旺格病(Binswanger's disease, BD)的进行性白质损害患者构成了从单纯血管性疾病到合并神经变性病变的疾病谱。BD患者是一个相对同质性的亚组,存在缺氧缺血、腔隙性梗死和炎症,它们协同作用破坏血脑屏障和髓鞘。通过临床、脑脊液、神经心理学和影像学检查获得的多模式疾病标记物能促进该亚组患者的鉴别。本共识声明确定了一系列基于基础病理学改变的潜在生物学标记物,这将有助于诊断以及将来协作性治疗试验的患者选择。Gary A Rosenberg Anders Wallin Joanna M Wardlaw Hugh S Markus Joan Montaner Leslie Wolfson Costantino Iadecola Berislav V Zlokovic Anne Joutel Martin Dichgans Marco Duering Reinhold Schmidt Amos D Korczyn Lea T Grinberg Helena C Chui Vladimir Hachinski 王训师 张劼 陈涵丰 俞娅美 徐子奇 罗本燕 2016国际脑血管病杂志2016,24,6:18
3Visceral hypersensitivity and electromechanical dysfunction as therapeutic targets in pediatric functional dyspepsia显示文摘Functional gastrointestinal disorders(FGID) are common clinical syndromes diagnosed in the absence of biochemical,structural,or metabolic abnormalities. They account for significant morbidity and health care expenditures and are identifiable across variable age,geography,and culture. Etiology of abdominal pain associated FGIDs,including functional dyspepsia(FD),remains incompletely understood,but growing evidence implicates the importance of visceral hypersensitivity and electromechanical dysfunction. This manuscript explores data supporting the role of visceral hypersensitivity and electromechanical dysfunction in FD,with focus on pediatric data when available,and provides a summary of potential therapeutic targets.John M Rosen Jose T Cocjin Jennifer V Schurman Jennifer M Colombo Craig A Friesen 2014World Journal of Gastrointestinal Pharmacology and Therapeutics2014,5,3:16

7Alcohol dehydrogenase: A potential new marker for diagnosis of intestinal ischemia using rat as a model显示文摘AIM: Intestinal ischemia (Ii) is an abdominal emergency due to blockade of the superior mesenteric artery resulting in 60-100% mortality if diagnosed late. Changes in several biochemical parameters such as D (-)-lactate, Creatinine kinase isoenzymes and lactate dehydrogenase suggested for early diagnosis, lack specificity and sensitivity. Therefore a biochemical parameter with greater sensitivity needs to be identified.METHODS: Wistar male rats were randomly assigned into two groups; control sham operated (n = 24) and ischemic test (n = 24) group. Superior mesenteric arterial occlusion was performed in the ischemic test group for 1 h. Alcohol dehydrogenase (ADH) was estimated in blood from portal vein, right ventricle of heart, dorsal aorta (DA) and inferior vena cava (IVC). The Serum glutamic acid pyruvate transaminase (SGPT) was also estimated in blood from portal vein and right ventricle of heart.RESULTS: A significant increase (P<0.001) in the levels of ADH in both portal blood as well as heart blood of the test group (232.72±99.45 EU and 250.85±95.14 EU, respectively)as compared to the control group (46.39±21.69 EU and 65.38±30.55 EU, respectively) were observed. Similarly,increased levels of ADH were observed in blood samples withdrawn from DA and IVC in test animals (319.52±80.14EU and 363.90±120.68 EU, respectively) as compared to the control group (67.68±63.22 EU and 72.50±58.45 EU,respectively). However, in test animals there was significant increase in SGPT in portal blood (P = 0.054) without much increase in heart blood.CONCLUSION: Significant increase in the levels of ADH in portal and heart blood within 1 h of SMA occlusion without increase in SGPT in heart blood, suggests that the origin of ADH is from ischemic intestine and not from liver. Similarly, raised ADH levels were found in DA and IVC as well. IVC blood does represent peripheral blood sample. A raised level of ADH in test animals confirms it to be a potential marker in the early diagnosis of Ii.Upendra R Gumaste Mukund M Joshi Devendra T Mourya Pradip V Barde Ghanshyam K Shrivastav Vikram S Ghole 2005World Journal of Gastroenterology2005,11,6:9

13Precision Livestock Farming: Precision feeding technologies and sustainable livestock production显示文摘In order to be able to produce safe,uniform,cheap,environmentally-and welfare-friendly food products and market these products in an increasingly complex international agricultural market,livestock producers must have access to timely production related information.Especially the information related to feeding/nutritional issues is important,as feeding related costs are always significant part of variables costs for all types of livestock production.Therefore,automating the collection,analysis and use of production related information on livestock farms will be essential for improving livestock productivity in the future.Electronically-controlled livestock production systems with an information and communication technology(ICT)focus are required to ensure that information is collected in a cost effective and timely manner and readily acted upon on farms.New electronic and ICT related technologies introduced on farms as part of Precision Livestock Farming(PLF)systems will facilitate livestock management methods that are more responsive to market signals.The PLF technologies encompass methods for electronically measuring the critical components of the production system that indicate the efficiency of resource use,interpreting the information captured and controlling processes to ensure optimum efficiency of both resource use and livestock productivity.These envisaged real-time monitoring and control systems could dramatically improve production efficiency of livestock enterprises.However,further research and development is required,as some of the components of PLF systems are in different stages of development.In addition,an overall strategy for the adoption and commercial exploitation of PLF systems needs to be developed in collaboration with private companies.This article outlines the potential role PLF can play in ensuring that the best possible management processes are implemented on farms to improve farm profitability,quality of products,welfare of livestock and sustainability of the farm environment,especially as it related to intensive livestock species.T M Banhazi L Babinszky V Halas M Tscharke 2012International Journal of Agricultural and Biological Engineering2012,5,4:5

18Development and Validation of a Laboratory Aging Method for the Accelerated Simulation of Reclaimed Asphalt显示文摘The paper presented first results elaborated during the European Research Project Re-road which aims at the development of techniques for increasing the recycling rates of reclaimed asphalt. During service life surface asphalt courses are subjected to aging due to oxidation effects which causes the hardening of the binder and thereby a change in the chemical, physical and mechanical properties of the material. Surface courses often contain highly modified binders as well as special additives for improving the performance characteristics. As these layers inhibit the shortest service lives compared to other road construction layers every year high amounts of reclaimed surface asphalt are available for recycling. The question is raised how the reclaimed asphalt consisting of high quality and costly material components can be recycled for optimal added value. To analyze the asphalt mix service life performance and its recyclability during mix design a laboratory method was developed to simulate the real in-situ aging. First the effects of site aging on the binder and asphalt characteristics were presented. Three laboratory aging methods were discussed which aimed the accelerated aging which meets similar property changes as site aging. At last the effects of two different laboratory aging methods on the same SMA mixture were compared.MOLLENHAUER K PIERARD N TUSAR M MOUILLET V GABET T 2010Journal of Wuhan University of Technology(Materials Science)2010,25,4:3
19掺碲硒化镓晶体的光学性能(英文)显示文摘采用水平区熔法生长了碲(Te)掺杂浓度(质量百分比)分别为0.05%,0.1%,0.5%,1%,2%的硒化镓(GaSe)晶体,并分别对掺杂浓度为0.01%,0.07%,0.38%,0.67%,2.07%的GaSe∶Te晶体的光学性能进行了表征。首次研究了GaSe∶Te晶体中刚性层声子模式的转换。吸收光谱测试结果表明:当Te掺杂浓度小于0.38%时,振动中心位于0.59 THz附近的E'(2)刚性模式吸收峰强度可达最大值,这一过程与GaSe∶Te晶体光学性能的提高密切相关。但Te掺杂浓度的进一步提高会导致E'(2)刚性模式吸收峰强度逐渐减弱,当Te掺杂浓度为1%时,E'(2)刚性模式吸收峰基本消失。这两个过程与GaSe∶Te晶体光学质量的下降密切相关。因此,E'(2)刚性模式吸收强度达到最高时对应的掺杂浓度即是GaSe∶Te晶体中Te的最佳掺杂浓度,光整流产生太赫兹过程证实了此结论的正确性。古新安 朱韦臻 罗志伟 ANDREEV Y M LANSKII G V SHAIDUKO A V IZAAK T I SVETLICHNYI V A VAYTULEVICH E A ZUEV V V 2011中国光学2011,4,6:3
