1Tight junctions in inflammatory bowel diseases and inflammatory bowel disease associated colorectal cancer显示文摘Inflammatory bowel diseases are characterised by inflammation that compromises the integrity of the epithelial barrier. The intestinal epithelium is not only a static barrier but has evolved complex mechanisms to control and regulate bacterial interactions with the mucosal surface. Apical tight junction proteins are critical in the maintenance of epithelial barrier function and control of paracellular permeability. The characterisation of alterations in tight junction proteins as key players in epithelial barrier function in inflammatory bowel diseases is rapidly enhancing our understanding of critical mechanisms in disease pathogenesis as well as novel therapeutic opportunities. Here we give an overview of recent literature focusing on the role of tight junction proteins, in particular claudins, in inflammatory bowel diseases and inflammatory bowel disease associated colorectal cancer.Jonathan Landy Emma Ronde Nick English Sue K Clark Ailsa L Hart Stella C Knight Paul J Ciclitira Hafid Omar Al-Hassi 2016World Journal of Gastroenterology2016,22,11:39
2木薯产品营养成分的分析与比较研究显示文摘本试验对3种木薯产品及玉米对照样品的主要营养成分包括粗蛋白质、粗脂肪、粗纤维、粗灰分、无氮浸出物、总淀粉、支链淀粉、直链淀粉、氨基酸、非淀粉多糖、矿物质的含量及其体外干物质和淀粉消化率、淀粉颗粒特征等指标进行了比较研究。结果表明,与玉米对照相比,木薯产品粗蛋白质和氨基酸含量较低,蛋白质品质低劣;木薯粒粗脂肪、粗纤维、粗灰分含量均显著高于玉米(P<0.05);木薯渣无氮浸出物含量显著低于木薯干(P<0.05),而粗灰分和粗纤维含量均显著高于木薯干和玉米(P<0.05);木薯干和木薯粒的总淀粉含量与玉米相当,但直链淀粉/支链淀粉比值显著低于玉米(P<0.05),木薯渣中抗性淀粉含量显著高于其他木薯产品和玉米对照(P<0.05),玉米淀粉粒形态为不规则多面体,而木薯淀粉粒形态似球形;木薯产品中钙、钾、铁和锰的含量均显著高于玉米(P<0.05),而磷和锌的含量均显著低于玉米(P<0.05);玉米中可溶性非淀粉多糖(SNSP)含量显著低于3种木薯产品,且木薯渣中SNSP含量显著高于木薯干和木薯粒(P<0.05);木薯渣中不溶性非淀粉多糖含量显著高于木薯干和木薯粒(P<0.05),且其不溶性半乳糖的含量显著高于其他木薯产品及玉米(P<0.05);木薯粒干物质和淀粉消化率均显著高于木薯干、木薯渣和玉米(P<0.05),木薯渣干物质和淀粉消化率均显著低于玉米和木薯干(P<0.05)。本研究结果对木薯产品在饲料中的应用有一定的指导意义。唐德富 Iji P Choct M 汝应俊 宋淑玉 Clarke K L 2014中国畜牧兽医2014,41,9:15

4母猪难产的应对措施显示文摘当今猪生产系统中母猪难产并不常见,所占比例不到1%。母猪临近分娩时,大约每隔30~60分钟需进行产前观察。如果清楚母猪正常分娩过程,母猪出现难产时可第一时间采取相关措施。分娩前要保证分娩环境清洁和干燥(图1);预产期前1~5天将妊娠母猪赶往分娩栏(图2)。Singleton W Amass S F Clark L K 朱勇文 2012养猪2012,,1:4
5Skin-gut axis:The relationship between intestinal bacteria and skin health显示文摘The gut microbiome is an emerging area of interest in medicine. Imbalances in the gut microbiome have been linked to a number of disease states such as obesity and type 2 diabetes. The relationship between normally residing intestinal bacteria(the gut microbiota) and their potential role in the pathogenesis of skin diseases is an area of research for which we are only beginning to understand. Small studies have demonstrated underlying changes in the gut microbiome of patients with certain dermatological diseases. Interestingly, studies suggest that probiotics may have a role in the treatment of atopic dermatitis. However, the concept of the 'skin-gut axis' is a newly emerging and important avenue of investigation, still lacking in pathobiological explanations. This review will introduce and describe the intestinal microbiome as it relates to skin health in a complex communication network between the immune system, endocrine system, metabolic system, and nervous system.Alexandra R Vaughn Manisha Notay Ashley K Clark Raja K Sivamani 2017World Journal of Dermatology2017,6,4:4
6通过取出物研究回顾采用28mm和32mm直径假体的全髋关节置换术显示文摘对翻修取出的直径为28 mm和32 mm的球头研究发现,髋臼和股骨颈部撞击可能经常发生。超高分子量聚乙烯、钴铬合金和氧化铝陶瓷界面可能都会因此受累。其中,钴铬合金界面和氧化铝陶瓷界面的坚硬内衬和金属被托设计使它们发生撞击的风险增加。造成不良影响的常见途径包括撞击、金属磨削转移和条状磨损。这些行为与采用陶瓷假体的全髋置换术后的异响有关。我们对老化的36 mm的氧化铝基复合陶瓷(AMC)球头(B IOLOX delta,CeramTec AG,Plochingen,Germany)进行模拟试验机磨损试验,在微分离模式下进行100万次的负载周期测试,发现条状磨损区的单斜相部分比主要磨损区和无磨损区的要高。这与我们之前对未老化陶瓷材料进行的模拟试验机试验结果一样,在那项研究中我们对纯氧化铝陶瓷(B IOLOX forte,同一生产商)和氧化铝基复合陶瓷都进行了对比研究,在经过500万次负载周期后我们发现,与对照组Forte球头-Forte内衬相比,Delta球头-Forte内衬和Delta球头-Delta内衬可以分别使磨损降低3倍和7倍。这表明Delta球头比Forte球头更能抵抗条状磨损的形成。因此,在髋关节假体的设计中使用大直径Delta陶瓷界面应该具有临床效益。I.

7壳牌对未来车用能源多元化发展趋势的思考显示文摘面对能源短缺和环境污染的双重挑战,交通领域的转型升级不可避免。本文结合未来车用动力系统的发展趋势,对交通运输领域中应用的多种先进动力系统、清洁能源及替代燃料进行综述和评价,包括目前主要使用的传统液态化石燃料即汽、柴油及先进内燃机技术,清洁替代燃料(如生物燃料、天然气合成油(GTL)燃料、电转液(PTL)燃料、液化天然气(LNG)等),以及电气化动力系统(包括混合动力、纯电动和燃料电池)等,并着重讨论液体燃料。壳牌认为没有一种单一的解决方案可以解决复杂的能源问题,未来交通能源结构将呈现多种能源并存的特点,并分别适用于不同的场景。该文还介绍了壳牌近期基于不同政治、经济和社会发展程度提出的3种远景(壳牌“高山”、“海洋”和“天空”远景),提出壳牌对未来车用能源领域转型脱碳发展情景的思考。贾恬 郑彬 Warnecke W Kolbeck A Aradi A Kofod M Clark R Wilbrand K 2020汽车安全与节能学报2020,11,1:2
