1中国北方棉区转基因抗虫棉对棉苗蚜及其两种天敌的影响(英文)显示文摘2 0 0 1年田间小区试验研究了转 Bt基因棉和转双价基因 ( Bt+ Cp TI)棉对棉苗蚜及其天敌种群动态的影响 ;室内研究了转基因抗虫棉对两种棉蚜天敌的生物学影响。结果表明 ,转基因抗虫棉对棉蚜种群数量的影响不明显 ,未达显著水平。单作转基因棉田棉蚜发生期比麦套棉田提前 5天左右 ,发生数量是麦套棉田的 1 .6倍 ,表明麦棉套作可有效的控制苗蚜的为害。室内研究表明 ,异色瓢虫对用 Bt棉处理的的棉蚜的捕食量比对照增加 2 2 .0 % ,棉蚜茧蜂对用 Bt棉处理的棉蚜的寄生率降低 2 3.5 %。Velders R M 崔金杰 夏敬源 vander WerfW 2002棉花学报2002,14,3:23
2Serum leptin levels and insulin resistance are associated with gallstone disease in overweight subjects显示文摘AIM: To establish an association between the serum leptin levels and the development of gallstone disease (GD).METHODS: We carried out a non-matched case-controlled study in a university hospital in Mexico City. Two hundred and eighty-seven subjects were included: 97 cases with gallstones and 190 controls. Body mass index (BMI), fasting plasma leptin, insulin, serum lipid, and lipoprotein levels were measured. Insulin resistance was calculated by homeostasis model assessment (HOMA-IR). Unconditional logistic regression analysis (univariate and multivariate)stratified by BMI was used to calculate the risk of GD.RESULTS: The multivariate conditional regression analysis revealed a model for those patients with BMI <30. The selected variables in the model were HOMA-IR index with OR = 1.31, P= 0.02 and leptin higher than median with OR = 2.11, P= 0.05. In the stratum of BMI ≥30, we did not find a useful model.CONCLUSION: We concluded that insulin resistance and the development of GD appears to be associated with serum leptin levels in subjects with overweight, but not in obese subjects with similar metabolic profiles.Nahum Méndez-Sánchez Luisa B Bermejo-Martínez Yolanda Vi(n|~)als Norberto C Chavez-Tapia Irina Vander Graff Guadalupe Ponciano-Rodríguez Martha H Ramos Misael Uribe 2005World Journal of Gastroenterology2005,11,39:11
3Exercise training in hypertension:Role of microRNAs显示文摘Hypertension is a complex disease that constitutes an important public health problem and demands many studies in order to understand the molecular mechanisms involving his pathophysiology. Therefore, an increasing number of studies have been conducted and new therapies are continually being discovered. In this context, exercise training has emerged as an important non-pharmacological therapy to treat hypertensive patients, minimizing the side effects of pharmacological therapies and frequently contributing to allow pharmacotherapy to be suspended. Several mechanisms have been associated with the pathogenesis of hypertension, such as hyperactivity of the sympathetic nervous system and renin-angiotensin aldosterone system,impaired endothelial nitric oxide production, increased oxygen-reactive species, vascular thickening and stiffening, cardiac hypertrophy, impaired angiogenesis, and sometimes genetic predisposition. With the advent of microRNAs(miRNAs), new insights have been added to the perspectives for the treatment of this disease, and exercise training has been shown to be able to modulate the miRNAs associated with it. Elucidation of the relationship between exercise training and miRNAs in the pathogenesis of hypertension is fundamental in order to understand how exercise modulates the cardiovascular system at genetic level. This can be promising even for the development of new drugs. This article is a review of how exercise training acts on hypertension by means of specific miRNAs in the heart, vascular system, and skeletal muscle.Vander Josédas Neves Tiago Fernandes Fernanda Roberta Roque Ursula Paula RenóSoci Stéphano Freitas Soares Melo Edilamar Menezes de Oliveira 2014World Journal of Cardiology2014,6,8:9
4荷兰高达公司的马铃薯蒸汽去皮系统显示文摘在马铃薯加工过程中,蒸汽去皮是关系到降低成本和提高产品质量的关键环节。荷兰高达公司30年来致力于去皮技术的研究。他们把目标定位于降低生产成本,特别是降低水污染的研究,所研制的马铃薯蒸汽去皮系统生产设备及生产线,经过不断的改进和发展,取得了成功。早在20世纪60年代,荷兰最大的马铃薯加工企业(其中多数是法式薯条生产企业),开始了生产线的运营。随着生产线能力的迅速扩大,废水问题成了荷兰社会的焦点。马铃薯加工过程中的水污染主要产生于去皮工序。于是,马铃薯加工设备制造商开始寻找降低水污染的途径。在荷兰和美国,生产商不断地推出具有世界先进水平的去皮机。高达公司最新研制的分离—定子式去皮机、刷加带式清皮机及其去皮生产线已经投放市场。目前,在许多欧洲国家,以及美国、加拿大、澳大利亚、日本、中国等国家的大型马铃薯和蔬菜加工企业都在使用高达公司的机器。Peter vander Schoot 沈翔翻 2003农产品加工2003,,5:5
5Epigenetic profiles of pre-diabetes transitioning to type 2 diabetes and nephropathy显示文摘AIM: To examine DNA methylation profiles in a longitudinal comparison of pre-diabetes mellitus(Pre-DM) subjects who transitioned to type 2 diabetes mellitus(T2DM).METHODS: We performed DNA methylation study in bisulphite converted DNA from Pre-DM(n = 11) at baseline and at their transition to T2 DM using Illumina Infinium Human Methylation27 Bead Chip, that enables the query of 27578 individual cytosines at Cp G loci throughout the genome, which are focused on the promoter regions of 14495 genes.RESULTS: There were 694 Cp G sites hypomethylated and 174 Cp G sites hypermethylated in progression from Pre-DM to T2 DM, representing putative genes involved in glucose and fructose metabolism, inflammation, oxidative and mitochondrial stress, and fatty acid metabolism. These results suggest that this high throughput platform is able to identify hundreds of prospective Cp G sites associated with diverse genes that may reflect differences in Pre-DM compared with T2 DM. In addition, there were Cp G hypomethylation changes associated with a number of genes that may be associated with development of complications of diabetes, such as nephropathy. These hypomethylation changes were observed in all of the subjects.CONCLUSION: These data suggest that some epigenomic changes that may be involved in the progression of diabetes and/or the development of complications may be apparent at the Pre-DM state or during the transition to diabetes. Hypomethylation of a number of genes related to kidney function may be an early marker for developing diabetic nephropathy.Thomas A Vander Jagt Monica H Neugebauer Marilee Morgan Donald W Bowden Vallabh O Shah 2015World Journal of Diabetes2015,6,9:5

7Pharmacologic rationale for treatments of peritoneal surface malignancy from colorectal cancer显示文摘The peritoneal surfaces of the abdomen and pelvis are important sites for the dissemination of gastrointestinal and gynecologic malignancy. Transcoelomic dissemination of cancer cells gives rise to carcinomatosis, which, without special treatment, is a fatal manifestation of these diseases. To treat peritoneal carcinomatosis, cytoreductive surgery removes gross disease plus perioperative intraperitoneal and perioperative intravenous chemotherapy eradicates microscopic residual disease and chemical compatibilities. Chemotherapy agents are administered either by the intraperitoneal or intravenous route, based on their pharmacologic properties. A peritoneal-plasma barrier, which retards the clearance of high molecular weight chemotherapy from the peritoneal cavity, results in a large exposure of small cancer nodules on abdominal and pelvic surfaces. Tissue penetration of the intraperitoneal chemotherapy is facilitated by moderate hyperthermia (41-42℃). Targeting of intravenous chemotherapy to the peritoneal surface is facilitated by the intraperitoneal heat. A constant dose of chemotherapy agent and volume of carrier solution, based on body surface area, allows prediction of systemic drug exposure and systemic toxicity. Timing of the hyperthermic chemotherapy as a scheduled part of the surgical procedure to uniformly expose all peritoneal surfaces is crucial to success.PaulH Sugarbaker Kurt Vander Speeten O Anthony Stuart 2010World Journal of Gastrointestinal Oncology2010,2,1:4
8社区卫生服务守门人好不好——欧洲18个国家病人满意度与转诊制度的关系显示文摘目的探讨守门人制度与人群对全科医生服务满意度的关系。方法研究涉及了18个国家,包括欧盟成员国及挪威、冰岛和瑞士。本研究有两个数据来源:(1)请各国专家选择17种不同类型的卫生服务,然后计算各种服务的“直接可及性”,即病人可以自由选择的服务占总服务的比例;(2)采用EUROPEP工具,测量病人对全科医生服务的满意度,该测量涉及了14个欧洲国家。结果直接获得卫生服务越多的国家的病人对全科医生服务的满意度越高于需要转诊的国家(r=0.54,P=0.05)。对全科医学服务组织方面(即服务的安排,主要考虑到等待时间和预约可能)的满意度与服务“直接可及性”呈正相关(r=0.67,P=0.01)。对医患沟通的满意度以及对医学服务技术的满意度与“直接可及性”无关(r=0.46、0.41,P>0.05)。结论病人认为“直接可及性”是很重要的。如果病人可以自由地选择卫生服务提供者的类型,那么就会给全科医生服务更积极的评价。不过这种满意主要表现在全科医学服务的组织方面。是否能直接可及各种服务并不影响病人对全科医生服务质量的评价。杨辉 Madelon W.Kroneman Hans Maarse Jouke Vander Zee 2007中国全科医学2007,10,1:4
9一种环境友好的鞣制工艺显示文摘研制一种新的鞣制工艺(亮湿革),用此工艺可以生产出一种合格的汽车内饰浅色革。此工艺是无铬、无醛、无有机溶剂挥发的绿色工艺。工艺的重点是使用了凯米拉公司提供的无毒、无害、绿色、安全的鞣剂。与传统的铬鞣革和醛鞣革相比,新工艺无论对环境或在经济上考虑都有很大的优势,具体来说,与传统的铬鞣革相比,可使废水中化学需氧量(COD)降低60%,悬浮液体降低61%,氮含量降低65%,此外这种工艺生产出的亮湿革的挥发性化合物比蓝湿革降低43%,比白湿革降低8%,更为重要的是,真正地做到了无铬废水排放。Anna Bacardit Stefan vander Burgh Jordi Armengol Luis Ollé 孙海云 金博 2014皮革与化工2014,31,4:3

15抗生素对人中性白细胞移动性和粘附性的体外试验显示文摘趋化性是多形核白细胞(PMN_s)的主要功能之一,可使它们局部定位和移动到发炎部位。趋化性包含的主要标志是C5a,它是一种由C5a受体识别的补体级联(complement cascade)产物,fMLP是一种通过fMLP受体识别的许多甲酰化细菌肽类的小分子肽原型;LTB_4是被各自不同的细胞,特别是PMN_s所分泌的一种白三烯(leukotriene),和由单核和多形核吞噬细胞产生的血小板活性因子(PAF)。某些抗生素能显示出干扰PMN_s的移动作用。研究PMN_s移动的两个最通用的方法是Nelson等的琼脂糖法和Boyden Chamber法,后法主要取决于PMNs的变形性,且该法具有很高的变异性。Vander Auwera P. 孙启武 1990国外医药(抗生素分册)1990,11,5:2
