1中国两栖动物保护需求总述显示文摘通过对中国两栖动物物种生物多样性现状的全面分析,与世界许多国家相比,中国是一个重要的全球优先保护地区.横断山区、南岭山区和武夷山区3个区域的两栖动物物种多样性特别丰富.有尾两栖类物种较无尾类受胁程度更高.几个物种数相对较少的铃蟾科、隐腮鲵科、小鲵科和蝾螈科显示出了高的受胁倾向.像世界其它地方一样,高海拔地区溪流繁殖的森林物种受胁程度更高.对中国两栖动物而言,生境丧失、污染和过度捕捉是最主要的致危因素.过度捕捉虽然影响不如生境丧失深远,但它更可能导致一个物种种群的快速衰落.针对5个方面的保护挑战,提出了优先研究领域和保护行动方面的建议.谢锋 刘惠宁 Simon N Stuart Janice S Chanson Neil A Cox Debra L Fischman 2006中国科学(C辑)2006,36,6:28
2Conservation needs of amphibians in China: A review显示文摘The conservation status of all the amphibians in China is analyzed,and the country is shown to be a global priority for conservation in comparison to many other countries of the world.Three Chinese regions are particularly rich in amphibian diversity:Hengduan,Nanling,and Wuyi mountains.Sala-manders are more threatened than frogs and toads.Several smaller families show a high propensity to become seriously threatened:Bombinatoridae,Cryptobranchidae,Hynobiidae and Salamandridae.Like other parts of the world,stream-breeding,high-elevation forest amphibians have a much higher likeli-hood of being seriously threatened.Habitat loss,pollution,and over-harvesting are the most serious threats to Chinese amphibians.Over-harvesting is a less pervasive threat than habitat loss,but it is more likely to drive a species into rapid decline.Five conservation challenges are mentioned with recommendations for the highest priority research and conservation actions.Michael Wai Neng LAU Simon N STUART Janice S CHANSON Neil A COX Debra L FISCHMAN 2007Science China(Life Sciences)2007,50,2:12
3Haplotype of prostaglandin synthase 2/cyclooxygenase 2 is involved in the susceptibility to inflammatory bowel disease显示文摘AIM: Prostaglandin G/H synthase 2 (PTGS2 or COX2) is one of the key factors in the cellular response to inflammation.PTGS2 is expressed in the affected intestinal segments of patients with inflammatory bowel diseases (IBD). In IBD patients, non-steroidal anti-inflammatory drugs, which have been shown to reduce both the production and activity of PTGS2, may activate IBD and aggravate the symptoms.We aimed at examining genetic variants of PTGS2 that may be risk factors for IBD.METHODS: We genotyped 291 individuals diagnosed with IBD and 367 controls from the Dutch population for the five most frequent polymorphisms of the PTGS2 gene.Clinical data were collected on all patients. DNA was extracted via normal laboratory methods. Genotyping was carried out using multiplex PCR followed by the Invader Assay and the 5' exonuclease assay (TaqMan). New polymorphism screening was performed by pre-screening with denaturing high-performance liquid chromatography,followed by fluorescent sequencing.RESULTS: Allele 5209G was weakly associated with Crohn's disease (odds ratio [OR] 1.63, 95% confidence interval [CI] 1.03-2.57), and allele 8473T with ulcerative colitis (OR 1.50, 95%CI 1.00-2.27). The haplotype including both alleles showed a strong association with IBD (OR 13.15, 95%CI 3.17-116.15). This haplotype, while rare (-0.3%) in the general population, is found more frequently in patients (3.5%).CONCLUSION: Our data suggest that this haplotype of PTGS2 contributes to the susceptibility of IBD.David G Cox J Bart A Crusius Petra HM Peeters H Bas Bueno-de-Mesquita A Salvador Pe(n|~)a Federico Canzian 2005World Journal of Gastroenterology2005,11,38:10
4具有低动脉粥样硬化风险特征的专业耐力运动员的亚临床冠状动脉疾病发病率显示文摘研究表明,具有冠状动脉疾病(coronary artery disease,CAD)危险因素的中老年(健将)运动员比久坐个体冠状动脉钙化(coronary artery calcium,CAC)评分更高。尚没有研究评估具有低动脉粥样硬化风险特征的专业运动员的CAD患病率。刘莉 叶鹏 Merghani A Maestrini V Rosmini S Cox AT Dhutia H Bastiaenen R David S Yeo TJ Narain R Malhotra A Papadakis M Wilson MG Tome M AlFakih K Moon JC Sharma S 2017中华高血压杂志2017,25,6:8
5用可调式涡轮增压技术降低排放并改善扭矩特性显示文摘目前,欧洲80%的轿车柴油机已采用涡轮增压。随着排放标准的日益严格,在不久的将来,涡轮增压机型有望接近100%。目前的一个主要热点是在高速柴油机上采用可调式涡轮增压技术(VGT)。在一台1.8L直喷式柴油机上做了大量的稳态试验研究,旨在对可调式涡轮增压发动机与配置带放气阀增压器的基准发动机进行比较,以观其潜在的益处。在欧洲试验循环中对排放产物十分重视的部分负荷工况下,分别控制可调增压器的叶片位置和废气再循环(EGR)阀的位置,以优化排放指标。在不牺牲固定式增压发动机的燃油耗、烟度的前提下,在一些间断工况点测得的NO_X减少到45%。在满足最高爆发压力、烟度和涡轮前温度限制条件下,可调增压发动机与装有固定增压基准发动机相比最大扭矩提高了10%。Hawley J G Wallace F J Cox A 栾敏 董复兴 2000国外内燃机2000,,3:3
