1Evaluation of quantitative contrast harmonic imaging to assess malignancy of liver tumors:A prospective controlled two-center study显示文摘AIM: To establish the extent to which contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics facilitates the detection of hepatic tumors. METHODS: One hundred patients with histologically confirmed malignant or benign hepatic tumor (maximum size 5 cm) were analyzed. Contrast-enhanced ultrasound (bolus injection 2.5 mL SonoVue) was carried out with intermittent breath-holding technique using a multifrequency transducer (2.5-4 MHz). Native vascularization was analyzed with power Doppler. The contrast-enhanced dynamic ultrasound investigation was carried out with contrast harmonic imaging in true detection mode during the arterial,portal venous and late phases. Mechanical index was set at 0.15. Perfusion analysis was performed by post-processing of the raw data time intensity curve (TIC) analysis. The cut-off of the gray value differences between tumor and normal liver tissue was established using Receiver Operating Characteristic (ROC) analysis 64-line multi-slice computed tomography served as reference method in all cases. Magnetic resonance tomography was used additionally in 19 cases. RESULTS: One hundred patients with 59 malignant (43 colon,5 breast,2 endocrine metastases,7 hepatocellular carcinomas and 2 kidney cancers) and 41 benign (15 hemangiomas,7 focal nodular hyperplasias,5 complicated cysts,2 abscesses and 12 circumscribed fatty changes) tumors were included. The late venous phase proved to be the most sensitive for classification of the tumor type. Fifty-eight of the 59 malignant tumors were classified as true positive,and one as false negative. This resulted in a sensitivity of 98.3%. Of the 41 benign tumors,37 were classified as true negative and 4 as false negative,which corresponds to a specificity of 90.2%. Altogether,95.0% of the diagnoses were classified as correct on the basis of the histological classification. No investigator-dependency (P = 0.23) was noted. CONCLUSION: The results show the possibility of accurate prediction of malignancy of hepatic tumors with a positive prognostic value of 93.5% using advanced contrast-enhanced ultrasound. Contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics is a valuable tool to discriminate hepatic tumors.EM Jung DA Clevert AG Schreyer S Schmitt J Rennert R Kubale S Feuerbach F Jung 2007World Journal of Gastroenterology2007,13,47:15
2疝修补术:寻找理想的网片显示文摘要做到有效的网片修补是困难的。在过去的50年中,疝修补技术有了长足的进步,但仍然需要一些新的观念和方法来巩固疝修补术已经取得的成绩。在欧洲疝学会第30次国际大会上,疝修补术及网片试验评估领域的9名专家共同参加了一次圆桌会议,讨论当今疝修补术中亟待解决的问题;内容包括'理想'网片的定义及'理想'的网片材料。讨论的其他内容还包括轻量型网片的特点,网片替代物,外科医生在疝修补术中的作用,当今疝修补术中亟待解决的问题,以及最佳的动物试验模型。尽管人们对于理想网片的构成还没有定论,但对其重要的特点却有了更深的理解。希望这些建议可以促进疝治疗的发展,并催生出最为有效的疝修补网片材料。Bringman S Conze J Cuccumllo D Deprest j Junge K Klosterhalfen B Parra-Davila E Ramshaw B Schumpelick V 2010中国实用外科杂志2010,30,12:10
3Prunus genetics and applications after de novo genome sequencing:achievements and prospects显示文摘Prior to the availability of whole-genome sequences,our understanding of the structural and functional aspects of Prunus tree genomes was limited mostly to molecular genetic mapping of important traits and development of EST resources.With public release of the peach genome and others that followed,significant advances in our knowledge of Prunus genomes and the genetic underpinnings of important traits ensued.In this review,we highlight key achievements in Prunus genetics and breeding driven by the availability of these whole-genome sequences.Within the structural and evolutionary contexts,we summarize:(1)the current status of Prunus whole-genome sequences;(2)preliminary and ongoing work on the sequence structure and diversity of the genomes;(3)the analyses of Prunus genome evolution driven by natural and man-made selection;and(4)provide insight into haploblocking genomes as a means to define genome-scale patterns of evolution that can be leveraged for trait selection in pedigree-based Prunus tree breeding programs worldwide.Functionally,we summarize recent and ongoing work that leverages whole-genome sequences to identify and characterize genes controlling 22 agronomically important Prunus traits.These include phenology,fruit quality,allergens,disease resistance,tree architecture,and self-incompatibility.Translationally,we explore the application of sequence-based marker-assisted breeding technologies and other sequence-guided biotechnological approaches for Prunus crop improvement.Finally,we present the current status of publically available Prunus genomics and genetics data housed mainly in the Genome Database for Rosaceae(GDR)and its updated functionalities for future bioinformatics-based Prunus genetics and genomics inquiry.Maria JoséAranzana Véronique Decroocq Elisabeth Dirlewanger Iban Eduardo Zhong Shan Gao Ksenija Gasic Amy Iezzoni Sook Jung Cameron Peace Humberto Prieto Ryutaro Tao Ignazio Verde Albert G.Abbott Pere Arús 2019Horticulture Research2019,6,1:8

5Fault detection method with PCA and LDA and its application to induction motor显示文摘A feature extraction and fusion algorithm was constructed by combining principal component analysis(PCA) and linear discriminant analysis(LDA) to detect a fault state of the induction motor.After yielding a feature vector with PCA and LDA from current signal that was measured by an experiment,the reference data were used to produce matching values.In a diagnostic step,two matching values that were obtained by PCA and LDA,respectively,were combined by probability model,and a faulted signal was finally diagnosed.As the proposed diagnosis algorithm brings only merits of PCA and LDA into relief,it shows excellent performance under the noisy environment.The simulation was executed under various noisy conditions in order to demonstrate the suitability of the proposed algorithm and showed more excellent performance than the case just using conventional PCA or LDA.JUNG D Y LEE S M 王洪梅 KIM J H LEE S H 2010Journal of Central South University2010,17,6:3

9生理性线粒体破碎是心脏适应能量需求增加的正常现象显示文摘线粒体在心脏中起着双重作用:负责满足能量需求和调节细胞凋亡。通常认为,线粒体的分裂和碎裂是病理性应激(如缺血)的结果,是线粒体质量差的指标,并导致线粒体自噬和细胞死亡。然而,最近的研究表明,抑制裂变也导致线粒体功能减弱和心脏损害,说明裂变对维持心脏和线粒体生物能量平衡十分重要。刘莉 叶鹏 Coronado M Fajardo G Nguyen K Zhao M Kooiker KB Jung G Hu DQ Reddy S Sandoval E Stotland A Gottlieb RA Bernstein D 2018中华高血压杂志2018,26,1:2
