2Oxidative stress and male reproductive health显示文摘有缺点的精子功能的主要原因之一是氧化应力,它不仅破坏精子 DNA 的正直而且在精子血浆膜由于蛋白质和类脂化合物的并行的损坏限制这些房间的使肥沃的潜力。如此的氧化压力的起源看起来包含精子线粒体,它有一个趋势作为一篇序言产生 superoxide 阴离子的高水平到进入内在的 apoptotic 串联。不幸地,这些房间有很小的能力因为他们仅仅在基础切除修理(BER ) 拥有第一酶,对如此的攻击作出回应小径, 8-oxoguanine glycosylase 1 (OGG1 ) 。后者成功地创造一个 abasic 地点,而是精子因为他们缺乏下游的蛋白质,不能进一步处理氧化损害(APE1, XRCC1 ) 需要完成修理过程。在第一个有丝分裂的部门的 S 阶段的开始以前继续 BER 小径是卵母细胞的责任。如果一个错误被卵母细胞在开发的这个阶段犯,一个变化将被创造那将在身体在每个房间被代表。如此的机制可以在在作为年龄的后果在他们的细菌线承受了氧化应力的男性的后代观察的童年癌症和另外的疾病解释增加,环境或生活方式因素。在男不孕病人的精子的氧化 DNA 损坏的高流行可以为在 vitro 构思的孩子的健康有含意并且在细菌线为对免费激进的产生的起源的当前的研究担任一位司机。Robert J Aitken Tegan B Smith Matthew S Jobling Mark A Baker Geoffry N De Iuliis 2014Asian Journal of Andrology2014,16,1:48
3Role of the gut microbiota in inflammatory bowel disease pathogenesis: What have we learnt in the past 10 years?显示文摘Our understanding of the microbial involvement in inflammatory bowel disease(IBD) pathogenesis has increased exponentially over the past decade. The development of newer molecular tools for the global assessment of the gut microbiome and the identification of nucleotide-binding oligomerization domain-containing protein 2 in 2001 and other susceptibility genes for Crohn's disease in particular has led to better understanding of the aetiopathogenesis of IBD. The microbial studies have elaborated the normal composition of the gut microbiome and its perturbations in the setting of IBD. This altered microbiome or 'dysbiosis' is a key player in the protracted course of inflammation in IBD. Numerous genome-wide association studies have identified further genes involved in gastrointestinal innate immunity(including polymorphisms in genes involved in autophagy: ATG16L1 and IGRM), which have helped elucidate the relationship of the local innate immunity with the adjacent luminal bacteria. These developments have also spurred the search for specific pathogens which may have a role in the metamorphosis of the gut microbiome from a symbiotic entity to a putative pathogenic one. Here we review advances in our understanding of microbial involvement in IBD pathogenesis over the past 10 years and offer insight into how this will shape our therapeutic management of the disease in the coming years.Georgina L Hold Megan Smith Charlie Grange Euan Robert Watt Emad M El-Omar Indrani Mukhopadhya 2014World Journal of Gastroenterology2014,20,5:21

7Demand response:a strategy to address residential air-conditioning peak load in Australia显示文摘Rapid growth in electricity network peak demand is increasing pressure for new investment which may be used for only a few hours a year.Residential airconditioning is widely believed to be the prime cause of the rise in peak demand but,in the absence of detailed residential demand research,there is no bottom-up empirical evidence to support this supposition or to estimate its impact.This paper first examines the developments in network peak demand,at a national,network distribution,and local distribution feeder level to show recent trends in peak demand.Secondly,this paper applies analytics to the half-hourly consumption data of a sample of Ausgrid’s interval metered customers,combined with local weather data,to develop an algorithm which can recognize air-conditioner use and can identify consumption patterns and peak load.This estimate is then compared to system peaks to determine residential airconditioning’s impact on overall demand.Finally,this paper considers the future impacts of air-conditioning load on peak demand as penetration rates reaches saturation levels and new minimum energy performance standards take effect reducing new units peak impacts.Robert SMITH Ke MENG Zhaoyang DONG Robert SIMPSON 2013Journal of Modern Power Systems and Clean Energy2013,1,3:10
8Advances of drag-reducing surface technologies in turbulence based on boundary layer control显示文摘Our living environment is surrounded by turbulence, which is also a concern of the global energy consumption and the greenhouse gas emission, and the viscous force on the solid-liquid/solid-gas interface is an important part of the turbulence. Reducing friction force in turbulence to the greatest extent is becoming an urgent issue to be resolved at present. In this paper, the various state-of-the-art approaches of drag-reducing and energy-saving technologies based on the boundary layer control are reviewed, focusing on the polymer drag reduction additives, the micro-morphology, the super-hydrophobic surface, the micro air bubbles, the heating wall, the vibrant flexible wall and the composite drag reduction methods. In addition, the mechanisms of different drag reductions based on the boundary layer control and the potential applications in fluid engineering are discussed. This paper aims not only to contribute to a better understanding of drag reduction mechanisms, but also to offer new perspectives to improve the current drag-reducing and energy saving technologies.LUO Yuehao WANG Liguo GREEN Lork SONG Kenan WANG Liang SMITH Robert 2015Journal of Hydrodynamics2015,27,4:8

11Radiofrequency ablation for early oesophageal squamous neoplasia:Outcomes form United Kingdom registry显示文摘AIM:To report outcomes on patients undergoing radiofrequency ablation(RFA)for early oesophageal squamous neoplasia from a National Registry.METHODS:A Prospective cohort study from 8 tertiary referral centres in the United Kingdom.Patients with squamous high grade dysplasia(HGD)and early squamous cell carcinoma(ESCC)confined to the mucosa were treated.Visible lesions were removed by endoscopic mucosal resection(EMR)before RFA.Following initial RFA treatment,patients were followed up 3monthly.Residual flat dysplasia was treated with RFA until complete reversal dysplasia(CR-D)was achieved or progression to invasive Squamous cell cancer defined as infiltration into the submucosa layer or beyond.The main outcome measures were CR-D at 12 mo from start of treatment,long term durability,progression to cancer and adverse events.RESULTS:Twenty patients with squamous HGD/ESCC completed treatment protocol.Five patients(25%)had EMR before starting RFA treatment.CR-D was 50%at12 mo with a median of 1 RFA treatment,mean 1.5(range 1-3).Two further patients achieved CR-D with repeat RFA after this time.Eighty per cent with CR-D remain dysplasia free at latest biopsy,with median follow up 24 mo(IQR 17-54).Six of 20 patients(30%)progressed to invasive cancer at 1 year.Four patients(20%)required endoscopic dilatations for symptomatic structuring after treatment.Two of these patients have required serial dilatations thereafter for symptomatic dysphagia with a median of 4 dilatations per patient.The other 2 patients required only a single dilatation to achieve an adequate symptomatic response.One patient developed cancer during follow up after end of treatment protocol.CONCLUSION:The role of RFA in these patients re-mains unclear.In our series 50%patients responded at12 mo.These figures are lower than limited published data.Rehan J Haidry Mohammed A Butt Jason Dunn Matthew Banks Abhinav Gupta Howard Smart Pradeep Bhandari Lesley Ann Smith Robert Willert Grant Fullarton Morris John Massimo Di Pietro Ian Penman Marco Novelli Laurence B Lovat 2013World Journal of Gastroenterology2013,19,36:7
12经颅直流电刺激对精神分裂症认知功能的影响:一项双盲随机对照试验的4周随访显示文摘目的探索经颅直流电刺激(tDCS)干预对精神分裂症患者认知功能的作用。方法纳入具有认知功能损害的精神分裂症住院患者39例,随机分为刺激组和伪刺激组。两组疗程均为连续10个工作日,每日进行一次tDCS干预。电极阳极置于患者左侧背外侧前额叶区,阴极置于右侧眶上缘区,电流强度2mA,干预时间20min。研究期间患者均接受常规治疗。采用中文版MATRICS认知成套测验(MCCB)、节奏听觉串行加法任务(PASAT)、CogState成套测验(Cog State Battery)、“看眼读心”测验(RMET)进行治疗基线和干预结束后4周的认知功能评定。结果除社会认知外,刺激组在各领域分值及MCCB总分上均高于对照组,但是仅在信息处理速度上组间差异有统计学意义(F=4.087,P=0.051)。刺激组中MCCB总分改善的患者的基线认知功能显著优于未改善患者(Z=0.085,P=0.011)。结论tDCS对信息处理速度的调控上具有一定维持作用,但仍需要大样本研究进一步证实。王怡然 李伟 蒋江灵 曹歆轶 王继军 金华 John M.
