2Coarctation of the aorta:Management from infancy to adulthood显示文摘Coarctation of the aorta is a relatively common form of congenital heart disease, with an estimated incidence of approximately 3 cases per 10000 births. Coarctation is a heterogeneous lesion which may present across all age ranges, with varying clinical symptoms, in isolation, or in association with other cardiac defects. The first surgical repair of aortic coarctation was described in 1944, and since that time, several other surgical techniques have been developed and modified. Additionally, transcatheter balloon angioplasty and endovascular stent placement offer less invasive approaches for the treatment of coarctation of the aorta for some patients. While overall morbidity and mortality rates are low for patients undergoing intervention for coarctation, both surgical and transcatheter interventions are not free from adverse outcomes. Therefore, patients must be followed closely over their lifetime for complications such as recoarctation, aortic aneurysm, persistent hypertension, and changes in any associated cardiac defects. Considerable effort has been expended investigating the utility and outcomes of various treatment approaches for aortic coarctation, which are heavily influenced by a patient's anatomy, size, age, and clinical course. Here we review indications for intervention, describe and compare surgical and transcatheter techniques for management of coarctation, and explore the associated outcomes in both children and adults.Rachel D Torok Michael J Campbell Gregory A Fleming Kevin D Hill 2015World Journal of Cardiology2015,7,11:27

4利用RNA干扰技术抑制水稻淀粉极限糊精酶基因表达显示文摘构建了含极限糊精酶基因片段反向重复结构的RNAi载体,抑制水稻籽粒中极限糊精酶基因表达获得了极限糊精酶基因功能缺失突变体。经酶切及序列测定证实,成功地构建了胚乳特异表达启动子启动的水稻极限糊精酶基因反向重复结构RNAi载体;通过根癌农杆菌(Agrobacterium tumefaciens)介导水稻(Oryza sativa sp.japonica)转化,经PCR及Southern杂交检测,获得28个水稻转基因再生株系;以极限糊精酶抗体对转基因株系胚乳发育期籽粒蛋白质进行Western杂交,并经SDS-PAGE极限糊精酶活性检测,结果显示,该反向重复结构在胚乳发育期表达,减少了极限糊精酶的积累,获得了不同沉默效果的转基因株系。转化株系012的极限糊精酶活性只有野生型的10%,表明该载体可有效地抑制水稻胚乳中极限糊精酶的活性。黄冰艳 李忠谊 吉万全 海燕 Fleming J Morell M Rahman S 2007农业生物技术学报2007,15,1:13
5自动化显微镜检测和数字化胸片诊断系统在肺结核筛查中的应用显示文摘中国有世界上第二大的结核病疫情(仅次于印度),具有较高的结核病感染、发病、耐药以及病死率。因此,快速、准确的诊断,以及时采取治疗,是控制这种疾病的关键问题。涂片荧光显微镜与金胺-O染色是在病理实验室检测肺结核抗酸杆菌(acid fast bacilli,AFB)最常用的诊断方法。但是以眼睛观察显微镜来筛查检测抗酸杆菌是一项烦琐、劳动密集型任务。低质量、不一致的痰涂片染色技术,标本碎屑,人眼视觉的变异和疲劳等因素会导致灵敏度低至40%。使用基于人工智能(artificial intelligence,AI)计算机辅助诊断(computer aided diagnostic,CAD)技术的自动显微镜系统对结核病进行自动诊断,提供了一个有效解决当前痰涂片诊断结核病所存在的缺陷。胸部X射线片也是世界卫生组织认定的非常有效的快速分流和转诊检测方法。但是,在不发达地区,因放射医生缺乏,它无法为大量的感染人群提供服务。为解决这一需要,将先进的数字化医学影像精准诊断应用于肺结核(pulmonary tuberculosis,PTB)检测,基于人工智能的CAD自动化智能系统,为肺结核的数字化医学影像精准诊断开辟了一条新路。Fleming Y.M.Lure Stefan Jaeger Sameer Antani Shenwen Quan 2017新发传染病电子杂志2017,2,1:11

9Metabolism pathways of arachidonic acids:mechanisms and potential therapeutic targets显示文摘The arachidonic acid(AA)pathway plays a key role in cardiovascular biology,carcinogenesis,and many inflammatory diseases,such as asthma,arthritis,etc.Esterified AA on the inner surface of the cell membrane is hydrolyzed to its free form by phospholipase A2 (PLA2),which is in turn further metabolized by cyclooxygenases(COXs)and lipoxygenases(LOXs)and cytochrome P450(CYP)enzymes to a spectrum of bioactive mediators that includes prostanoids,leukotrienes(LTs),epoxyeicosatrienoic acids(EETs),dihydroxyeicosatetraenoic acid(diHETEs),eicosatetraenoic acids(ETEs),and lipoxins(LXs).Many of the latter mediators are considered to be novel preventive and therapeutic targets for cardiovascular diseases(CVD),cancers,and inflammatory diseases.This review sets out to summarize the physiological and pathophysiological importance of the AA metabolizing pathways and outline the molecular mechanisms underlying the actions of AA related to its three main metabolic pathways in CVD and cancer.progression will provide valuable insight for developing new therapeutic drugs for CVD and anti-cancer agents such as inhibitors of EETs or 2J2.Thus,we herein present a synopsis of AA metabolism in human health,cardiovascular and cancer biology,and the signaling pathways involved in these processes.To explore the role of the AA metabolism and potential therapies,we also introduce the current newly clinical studies targeting AA metabolisms in the different disease conditions.Bei Wang Lujin Wu Jing Chen Lingli Dong Chen Chen Zheng Wen Jiong Hu Ingrid Fleming Dao Wen Wang 2021Signal Transduction and Targeted Therapy2021,6,3:7
10胚乳特异sbeⅡa启动子在小麦中的评价及特性分析显示文摘淀粉的合成是一个复杂的生化过程。sbeⅡa基因是淀粉合成过程中的关键酶基因之一,在小麦籽粒成熟过程中对淀粉,尤其对支链淀粉的生物合成调控起重要作用。为了解sbeⅡa基因的调控机理及其胚乳特异表达特性,利用APCR方法克隆了sbeⅡa启动子3094 bp片段,并对该片段进行测序,同时利用GUS瞬间表达体系对sbeⅡa启动子序列进行不同片段的功能缺失研究。研究结果表明,3094 bp序列(存在于sbe.g融合体中)具有稳定的启动子活性,而5'或3'缺失体的启动子活性明显降低。在sbeⅡa启动子中间缺失体中,一些缺失体仅有微弱活性,但sbe.e在缺失-1579—1210 bp片段情况下,却具有比sbe.g(含启动子全长序列)还要高的启动子活性,研究初步证明,一些固定序列(motifs),如-300 bp因子、G盒以及醇溶蛋白盒(Prolamin box)等作为正调控因子在决定启动子胚乳特异表达模式中是必需的,而且在-1579—1210 bp片段中也存在一些负调控因子或固定序列。在瞬间表达检测体系中,小麦胚乳组织年龄对检测结果有着重要影响。苗红梅 Fleming Joy E 吕德彬 韩锦峰 2004科学通报2004,49,5:7

12Chemopreventive and Growth Inhibitory Effects of Selenium显示文摘There is very convincing evidence that a high dietary level of selenium substantially reduces the incidence of a wide variety of animal cancers. The human epidemiological evidence is less clear cut, but overall suggests that selenium may be protective: the evidence is strongest in men in relation to gastro-intestinal cancers. There is evidence that dietary selenium compounds reduce the formation of DNA adducts by carcinogens. Selenium compounds also inhibit growth in vitro and induce apoptosis. In general, there is a good correlation between the effectiveness of selenium compounds in chemoprevention and growth inhibition, implying that the mechanisms of growth inhibition and chemoprevention may be similar and that a major factor in the chemopreventive effects of selenium compounds in vivo is their ability to retard outgrowth of pre-malignant cells. Various hypotheses have been advanced as to how selenium compounds might prevent tumour cellgrowth. One is that they cause apoptosis by inducing oxidative stress. However, we have shown that the most potent selenium compound, selenodiglutathione (SDG), a natural metabolite of selenite, does not induce oxidative stress, at least not in the sarne way as other oxidants such as H2O2 and diamide. Firstly, a partially selenium-resistant variant cell line does not show increased resistance to H2O2. Moreover, SDG does not induce widespread tyrosine phosphorylation, including MAP and SAN kinases, like other oxidants such as H2O2 and diamide and its effects are not reversed by pretreatment with the tyrosine kinase inhibitor, herbimycin. Our experiments with the selenium-resistant variant suggest that a novel selenium-binding protein may be involved in growth inhibition byP. R. HARRISON J. LANFEAR L. WU J. FLEMING L. MCGARRY, AND L.

19Fractal analysis of retinal vasculature in normal subjects on ultra-wide field fluorescein angiography显示文摘AIM: To evaluate the fractal feature of the retinal vasculature of normal eyes on a stereographic projected and montaged ultra-wide field(UWF) fluorescein angiography(FA).METHODS: Prospective, observational, cross-sectional study. Totally 59 eyes of 31 normal subjects were imaged using the Optos 200 Tx. Images obtained at different gaze angles stereographically projected and montaged. The early-phase UWF FA frames were processed to segment the retinal vasculature and the results were exported as binary masks. The fractal dimension(FD) was calculated using the box-counting method.RESULTS: The global FD for the entire retina was 1.6±0.04, with no difference between males and females(1.59±0.04 vs 1.61±0.04, P=0.084) or between right and left eyes(1.6±0.04 vs 1.6±0.05, P=0.61). FD was nonuniformly distributed among four quadrants(P<0.001) and decreased as the distance from the fovea increased(P<0.001). A negative association was observed between FD and age(R=-0.37, P=0.006), and this relationship was observed in the posterior and mid-peripheral retina(P<0.05) but absent in far-periphery(P>0.05).CONCLUSION: Fractal geometry is non-uniformly distributed across the retina in normal eyes and decreases from the fovea to the far-periphery. Subjects with an older age tend to have a smaller FD, however, the FD in the farperiphery does not appear to be influenced by age.Wen-Ying Fan Alan Fleming Gavin Robertson Akihito Uji Jano van Hemert Michael Singer Min Sagong Michael Ip SriniVas R.Sadda 2020International Journal of Ophthalmology(English edition)2020,13,7:3
