1Assessment of the uncertainties in temperature change in China during the last century显示文摘We have used the China Homogenized Historic Temperature dataset and some long-term station series of the neighbor countries from CRUTEM3,a 5°×5° gridded dataset of monthly mean temperature since 1900,to provide a 107-year record of surface temperature trends and variability.We derived a comprehensive set of uncertainty estimates to accompany the data:measurement and sampling errors,uncertainties in temperature bias estimates,and uncertainties arising from limited observational coverage on large-scale averages have all been estimated.We reanalysed the temperature changes during the period of record.The best estimates of trends for 1900-2006 with uncertainties at 95% confidence range are about 0.09±0.017°C/decade for the year as a whole,and 0.14±0.021°C/decade,0.11±0.021°C/decade,0.04±0.017°C/decade,and 0.07±0.017°C/decade for winter,spring,summer and autumn respectively.For 1954-2006,the trends for annual,winter,spring,summer and autumn are:0.26±0.032°C/decade,0.35±0.046°C/decade,0.25±0.051°C/decade,0.16±0.037°C/decade and 0.22±0.055°C/decade.Winter saw the most significant warming trend in both 1900-2006 and 1954-2006,while during the most recent period(the satellite era,1979-2006),all the seasons show similar warming trends:0.45±0.13°C/decade,0.51±0.11°C/decade,0.52±0.16°C/decade,0.37±0.10°C/decade and 0.50±0.16°C/decade for annual,winter,spring,summer and autumn.Trends arising from urbanization have been evaluated as less than 5% of the total warming trend for 1951-2001,so this bias was not removed.LI QingXiang DONG WenJie LI Wei GAO XiaoRong JONES P KENNEDY J PARKER D 2010Chinese Science Bulletin2010,55,19:26
2儿童多形性低级别神经上皮性肿瘤(PLNTY):一种具有少突胶质细胞瘤样形态的致癫痫性肿瘤,伴异常CD34表达及MAP激酶途径的基因改变显示文摘影响儿童和青年人的致癫痫性肿瘤是一组形态多样的神经上皮性肿瘤,表现出不同程度的胶质和(或)神经元分化。近期分子分析技术的进步,包括全DNA测序及甲基化分析,能够应用于这些肿瘤更加精确的与生物学相关的分类。本文描述了一种独特的形态和分子特征的致癫痫性肿瘤——儿童多形性低级别神经上皮性肿瘤(PLNTY),该肿瘤可能占儿童少突胶质细胞瘤样肿瘤中的多数。Huse J T Snuderl M Jones D T 蔡珊珊 王行富 2017临床与实验病理学杂志2017,33,1:12
3Intentional ingestions of foreign objects among prisoners: A review显示文摘The intentional ingestion of foreign objects(IIFO) is described more commonly in prison populations than in the general population, with an estimated annual incidence of 1 in 1900 inmates in our state correctional facilities. Incidents often involve ingestion of small metal objects(e.g., paperclips, razor blades) or other commonly available items like pens or eating utensils. Despite ingestion of relatively sharp objects, most episodes can be clinically managed with either observation or endoscopy. Surgery should be reserved for those with signs or symptoms of gastrointestinal perforation or obstruction. For those with a history of IIFO, efforts should focus on prevention of recurrenceas subsequent episodes are associated with higher morbidity, significant healthcare and security costs. The pattern of IIFO is often repetitive, with escalation both in frequency of ingestions and in number of items ingested. Little is known about successful prevention strategies, but efforts to monitor patients and provide psychiatric care are potential best-practice strategies. This article aims to provide state-of-the art review on the topic, followed by a set of basic recommendations.David C Evans Thomas R Wojda Christian D Jones Andrew J Otey Stanislaw P Stawicki 2015World Journal of Gastrointestinal Endoscopy2015,7,3:10
4柑桔黄龙病的鉴定和柯赫氏定理(英文)显示文摘黄龙(梢)病被认为是世界柑橘生产上的毁灭性病害已超过一个世纪,但该病害的病原学至今还没有清晰地建立起来。根据16S rRNA基因序列分析,一组被称为'Candidatus Liberibacter species'的难培养细菌被认为与黄龙病相关。然而,要确定'Ca.Liberibacter spp.'是黄龙病病原的柯赫氏定理并没有真正完成。令我们担忧的是,近年来有些文献频频指出'Ca.Liberibacter spp.'是黄龙病的病原,其实该细菌与柑橘寄主的直接病理反应还没有完全确定。我们建议,在黄龙病病原学清楚之前,文献报道在这方面需要有准确的阐述。Chen J Deng X Civerolo E L Lee R F Jones J B Zhou C Hartung J S Manjunath K L Brlansky R H 2011植物病理学报2011,41,2:10
5Apoptosis block as a barrier to effective therapy in non small cell lung cancer显示文摘Lung cancer, is the most common cause of cancer death in men and second only to breast cancer in women. Currently, the first line therapy of choice is platinumbased combination chemotherapy. A therapeutic plateau has been reached with the prognosis for patients with advanced non-small cell lung cancer(NSCLC) remaining poor. New biomarkers of prognosis as well as new therapies focusing on molecular targets are emerging helping to identify patients who are likely to benefit from therapy. Despite this, drug resistance remains the major cause for treatment failure. In this article we review the role of apoptosis in mediating drug resistance in NSCLC. Better understanding of this fundamental biological process may provide a rationale for overcoming the current therapeutic plateau.Ian Paul J Mark Jones 2014World Journal of Clinical Oncology2014,5,4:7
6Characterisation of Neonicotinoid and Pymetrozine Resistance in Strains of Bemisia tabaci(Hemiptera:Aleyrodidae)from China显示文摘Four strains of the Q biotype and one of the B biotype of the whitefly Bemisia tabaci collected from China were characterised for resistance to four neonicotinoid insecticides and pymetrozine.Q biotype strains showed moderate to strong resistance to imidacloprid,thiamethoxam and acetamiprid,but little or no cross-resistance to dinotefuron.Resistance to neonicotinoids was consistently associated with resistance to pymetrozine,despite the latter having a distinct(though unresolved)mode of action.The single B biotype strain proved largely susceptible to all the insecticides investigated.Resistance in the Q biotype strains was associated with over-expression of a cytochrome P450 monooxygenase gene,CYP6CM1,whose substrate specificity presumably accounts for the observed cross-resistance profiles.RAO Qiong XU Yong-hua LUO Chen ZHANG Hong-yu Christopher M Jones Greg J Devine KevinGorman Ian Denholm 2012Journal of Integrative Agriculture2012,11,2:7

8Dyslipidemia management in primary prevention of cardiovascular disease:Current guidelines and strategies显示文摘Cardiovascular disease is the leading cause of death in the United States. In 2010, the Centers for Disease Control and Prevention estimated that $444 billion was spent on cardiovascular diseases alone, about $1 of every $6 spent on health care. As life expectancy continues to increase, this annual cost will also increase, making costeffective primary prevention of cardiovascular disease highly desirable. Because of its role in development of atherosclerosis and clinical events, dyslipidemia management is a high priority in cardiovascular prevention. Multiple major dyslipidemia guidelines have been published around the world recently, four of them by independent organizations in the United States alone. They share the goal of providing clinical guidance on optimal dyslipidemia management, but guidelines differ in their emphasis on pharmacotherapy, stratification of groups, emphasis on lifestyle modification, and use of a fixed target or percentage reduction in low density lipoprotein cholesterol. This review summarizes eight major guidelines for dyslipidemia management and considers the basis for their recommendations. Our primary aim is to enhance understanding of dyslipidemia management guidelines in patient care for primary prevention of future cardiovascular risk.Aditya D Hendrani Tolulope Adesiyun Renato Quispe Steven R Jones Neil J Stone Roger S Blumenthal Seth S Martin 2016World Journal of Cardiology2016,8,2:5
9新型低密度脂蛋白胆固醇评估对全球血脂异常指南中次级靶标非高密度脂蛋白胆固醇和载脂蛋白B应用的影响显示文摘血脂异常指南通常推荐非高密度脂蛋白胆固醇(non-high-density lipoprotein-cholesterol,non-HDL-C)和载脂蛋白B(apolipoprotein B,apoB)作为主要靶点低密度脂蛋白胆固醇(low density lipoprotein cholesterol,LDL-C)的次要靶点。Sathiyakumar V Park J Quispe R Elshazly MB Michos ED Banach M Toth PP Whelton SP Blumenthal RS Jones SR Martin SS 刘青 叶鹏 2018中华高血压杂志2018,26,4:4
10一种新型的高频半导体量子点单电子泵显示文摘除了直流负电压外,还在浅法刻蚀出的GaAs/AlGaAs量子线上的两个金属指形门上分别叠加两个相位相差π的正弦信号,从而对形成量子点的两个势垒作不等幅调制.在无源漏偏压的情况下,通过周期形成的量子点实现了单电子的搬运.由于新的半导体量子点单电子泵不是依赖库仑阻塞效应通过隧穿进行单电子输运,因此,该器件就不会受到固定隧穿时间引起的低工作频率限制.在1.7K温度下,频率达到3GHz仍然可以观测到量子化电流平台,对应的电流值达到0.5nA量级.这种新器件提供了实现高速度、高精度搬运单电子的另一种可能途径.李玲 Kaestner B Blumenthal M D Giblin S Janssen T J B M Pepper M Anderson D Jones G Ritchie D A 高洁 2008物理学报2008,57,3:4

13Nat Genet:单基因突变导致过敏性皮炎的发生显示文摘最近,研究者们鉴定出了一类导致神经性皮炎发生的关键基因突变:CARDll。来自美国NIH过敏与传染病研究所的研究者们通过对四个没有血缘关系的患病家庭进行分析,发现了这一导致疾病产生的基因、Chi A Ma, Yuan Zhang, Michael A Weinreich, Jonathan J Lyons, Celeste G Nelson, Thomas DiMaggio, Kelly D Stone, Joshua D Milner Jeffrey R Stinson, Elisa Ruffo, Batsukh Dorjbal, Swadhinya Arjunaraja, Kelsey Voss, Andrew L Snow Jordan K Abbott, Pia J Hauk, Paul R Reynolds, Erwin W Gelfand Elisa Ruffo Salomé Glauzy, Natsuko Yamakawa, Eric Meffre Jennifer Stoddard, Julie Niemela, Sergio D Rosenzweig Yu Zhang, Helen F Matthews Joshua J McElwee Nina Jones Alejandro Palma, Matías Oleastro, Emma Prieto, Andrea R Bernasconi, Geronimo Dubra, Silvia Danielian, Jonathan Zaiat, Marcelo A Marti Brian Kim Megan A Cooper Neil Romberg 2017现代生物医学进展2017,17,27:3
14A survey of FLS2 genes from multiple citrus species identifies candidates for enhancing disease resistance to Xanthomonas citri ssp. citri.显示文摘Pathogen-associated molecular patterns(PAMPs)-triggered immunity(PTI)is an important component of plant innate immunity.In a previous study,we showed that the PAMP flg22 from Xanthomonas citri ssp.citri(Xflg22),the causal agent of citrus canker,induced PTI in citrus,which correlated with the observed levels of canker resistance.Here,we identified and sequenced two bacterial flagellin/flg22 receptors(FLS2-1 and FLS2-2)from‘Duncan’grapefruit(Citrus paradisi,CpFLS2-1 and CpFLS2-2)and‘Sun Chu Sha’mandarin(C.reticulata,CrFLS2-1 and CrFLS2-2).We were able to isolate only one FLS2 from‘Nagami’kumquat(Fortunella margarita,FmFLS2-1)and gene flanking sequences suggest a rearrangement event that resulted in the deletion of FLS2-2 from the genome.Phylogenetic analysis,gene structure and presence of critical amino acid domains all indicate we identified the true FLS2 genes in citrus.FLS2-2 was more transcriptionally responsive to Xflg22 than FLS2-1,with induced expression levels higher in canker-resistant citrus than in susceptible ones.Interestingly,‘Nagami’kumquat showed the highest FLS2-1 steady-state expression levels,although it was not induced by Xflg22.We selected FmFLS2-1,CrFLS2-2 and CpFLS2-2 to further evaluate their capacity to enhance bacterial resistance using Agrobacterium-mediated transient expression assays.Both FmFLS2-1 and CrFLS2-2,the two proteins from canker-resistant species,conferred stronger Xflg22 responses and reduced canker symptoms in leaves of the susceptible grapefruit genotype.These two citrus genes will be useful resources to enhance PTI and achieve resistance against canker and possibly other bacterial pathogens in susceptible citrus types.Qingchun Shi Vicente J Febres Jeffrey B Jones Gloria A Moore 2016Horticulture Research2016,3,1:3

16Magnetic nanowires fabricated by anodic aluminum oxide template—a brief review显示文摘Anodic aluminum oxide(AAO) with highly ordered nanoscale pores which are monodisperse and mutually parallel can be produced through a self-organized electrochemical process.Subsequent deposition of materials into the nanopores produces AAO embedded nanowire arrays.Whilst the templates can be further removed to obtain free individual nanowires,the embedded nanowires form an interesting nanocomposite structure.Recent research activities on the fabrication and characteriza-tion of AAO template based magnetic nanowires are reviewed in this article.Studies of specific systems are given as an example of the research in the area.LI WuXia ZHANG Jun SHEN TieHan JONES Grenville A GRUNDY Philip J 2011Science China(Physics,Mechanics & Astronomy)2011,54,7:3
17Recent advances in the diagnostic evaluation of pancreatic cystic lesions显示文摘Pancreatic cystic lesions(PCLs)are becoming more prevalent due to more frequent abdominal imaging and the increasing age of the general population.It has become crucial to identify these PCLs and subsequently risk stratify them to guide management.Given the high morbidity associated with pancreatic surgery,only those PCLs at high risk for malignancy should undergo such treatment.However,current diagnostic testing is suboptimal at accurately diagnosing and risk stratifying PCLs.Therefore,research has focused on developing new techniques for differentiating mucinous from non-mucinous PCLs and identifying high risk lesions for malignancy.Cross sectional imaging radiomics can potentially improve the predictive accuracy of primary risk stratification of PCLs at the time of detection to guide invasive testing.While cyst fluid glucose has reemerged as a potential biomarker,cyst fluid molecular markers have improved accuracy for identifying specific types of PCLs.Endoscopic ultrasound guided approaches such as confocal laser endomicroscopy and through the needle microforceps biopsy have shown a good correlation with histopathological findings and are evolving techniques for identifying and risk stratifying PCLs.While most of these recent diagnostics are only practiced at selective tertiary care centers,they hold a promise that management of PCLs will only get better in the future.Devarshi R Ardeshna Troy Cao Brandon Rodgers Chidiebere Onongaya Dan Jones Wei Chen Eugene J Koay Somashekar G Krishna 2022World Journal of Gastroenterology2022,28,6:3
18Macrophage secretory products induce an inflammatory phenotype in hepatocytes显示文摘AIM:To investigate the influence of macrophages on hepatocyte phenotype and function.METHODS:Macrophages were differentiated from THP-1 monocytes via phorbol myristate acetate stimulation and the effects of monocyte or macrophageconditioned medium on HepG2 mRNA and protein expression determined.The in vivo relevance of these findings was confirmed using liver biopsies from 147 patients with hepatitis C virus(HCV)infection.RESULTS:Conditioned media from macrophages,but not monocytes,induced a transient morphological change in hepatocytes associated with upregulation of vimentin(7.8±2.5-fold,P=0.045)and transforming growth factor(TGF)-β1(2.6±0.2-fold,P<0.001)and downregulation of epithelial cadherin(1.7±0.02-fold,P=0.017)mRNA expression.Microarray analysis revealed significant upregulation of lipocalin-2(17-fold,P <0.001)and pathways associated with inflammation,and substantial downregulation of pathways related to hepatocyte function.In patients with chronic HCV,realtime polymerase chain reaction and immunohistochemistry confirmed an increase in lipocalin-2 mRNA(F0 1.0 ±0.3,F1 2.2±0.2,F2 3.0±9.3,F3/4 4.0±0.8,P= 0.003)and protein expression(F1 1.0±0.5,F2 1.3± 0.4,F3/4 3.6±0.4,P=0.014)with increasing liver injury.High performance liquid chromatography-tandem mass spectrometry analysis identified elevated levels of matrix metalloproteinase(MMP)-9 in macrophageconditioned medium,and a chemical inhibitor of MMP-9 attenuated the change in morphology and mRNA expression of TGF-β1(2.9±0.2 vs 1.04±0.1,P<0.001) in macrophage-conditioned media treated HepG2 cells.In patients with chronic HCV infection,hepatic mRNA expression of CD163(F0 1.0±0.2,F1/2 2.8±0.3,F3/4 5.3±1.0,P=0.001)and MMP-9(F0 1.0±0.4,F1/2 2.8±0.3,F3/4 4.1±0.8,P=0.011)was significantly associated with increasing stage of fibrosis.CONCLUSION:Secreted macrophage products alter the phenotype and function of hepatocytes,with increased expression of inflammatory mediators,suggesting that hepatocytes actively participate in liver injury.Michelle Melino Victoria L Gadd Gene V Walker Richard Skoien Helen D Barrie Dinesh Jothimani Leigh Horsfall Alun Jones Matthew J Sweet Gethin P Thomas Andrew D Clouston Julie R Jonsson Elizabeth E Powell 2012World Journal of Gastroenterology2012,18,15:3
19Factor analysis identifies subgroups of constipation显示文摘AIM:To determine whether distinct symptom groupings exist in a constipated population and whether such grouping might correlate with quantifiable pathophysiological measures of colonic dysfunction.METHODS:One hundred and ninety-one patients presenting to a Gastroenterology clinic with constipation and 32 constipated patients responding to a newspaper advertisement completed a 53-item,wide-ranging selfreport questionnaire.One hundred of these patients had colonic transit measured scintigraphically.Factor analysis determined whether constipation-related symptoms grouped into distinct aspects of symptomatology.Cluster analysis was used to determine whether indi-vidual patients naturally group into distinct subtypes.RESULTS:Cluster analysis yielded a 4 cluster solution with the presence or absence of pain and laxative unresponsiveness providing the main descriptors.Amongst all clusters there was a considerable proportion of patients with demonstrable delayed colon transit,irritable bowel syndrome positive criteria and regular stool frequency.The majority of patients with these characteristics also reported regular laxative use.CONCLUSION:Factor analysis identified four constipation subgroups,based on severity and laxative unresponsiveness,in a constipated population.However,clear stratification into clinically identifiable groups remains imprecise.Philip G Dinning Mike Jones Linda Hunt Sergio E Fuentealba Jamshid Kalanter Denis W King David Z Lubowski Nicholas J Talley Ian J Cook 2011World Journal of Gastroenterology2011,17,11:3
20使用二甲双胍的禁忌证 证据显示应该修改二甲双胍的禁忌证显示文摘在英国前瞻性糖尿病研究(UNPOS)中,2型糖尿病患者被随机分入二甲双胍、磺酰脲类或胰岛素强化治疗组,3组患者取得了相似的血糖控制效果,微血管并发症终点事件显著降低。该项研究显示,肥胖患者使用二甲双胍治疗可以降低心血管事件的发生,二甲双胍治疗组的患者没有低血糖事件。G C Jones J P Macklin W D Alexander 李玉秀 2003英国医学杂志中文版2003,6,3:2
