| 2 | 在最后三扫描仪代的 CT 剂量和图象质量显示文摘 AIM: To compare the computed tomography(CT) dose and image quality with the filtered back projection against the iterative reconstruction and CT with a minimal electronic noise detector. METHODS: A lung phantom(Chest Phantom N1 by Kyoto Kagaku) was scanned with 3 different CT scanners: the Somatom Sensation, the Definition Flash and the Definition Edge(all from Siemens, Erlangen, Germany). The scan parameters were identical to the Siemens presetting for THORAX ROUTINE(scan length 35 cm and FOV 33 cm). Nine different exposition levels were examined(reference mAs/peek voltage): 100/120, 100/100, 100/80, 50/120, 50/100, 50/80, 25/120, 25/100 and 25 mAs/80 kVp. Images from the SOMATOM Sensation were reconstructed using classic filtered back projection. Iterative reconstruction(SAFIRE, level 3) was performed for the two other scanners. A Stellar detector was used with the Somatom Definition Edge. The CT doses were represented by the dose length products(DLPs)(mGycm) provided by the scanners. Signal, contrast, noise and subjective image quality were recorded by two different radiologists with 10 and 3 years of experience in chest CT radiology. To determine the average dose reduction between two scanners, the integral of the dose difference was calculated from the lowest to the highest noise level. RESULTS: When using iterative reconstruction(IR) instead of filtered back projection(FBP), the average dose reduction was 30%, 52% and 80% for bone, soft tissue and air, respectively, for the same image quality(P < 0.0001). The recently introduced Stellar detector(Sd) lowered the radiation dose by an additional 27%, 54% and 70% for bone, soft tissue and air, respectively(P < 0.0001). The benefit of dose reduction was larger at lower dose levels. With the same radiation dose, an average of 34%(22%-37%) and 25%(13%-46%) more contrast to noise was achieved by changing from FBP to IR and from IR to Sd, respectively. For the same contrast to noise level, an average of 59%(46%-71%) and 51%(38%-68%) dose reduction was produced for IR and Sd, respectively. For the same subjective image quality, the dose could be reduced by 25%(2%-42%) and 44%(33%-54%) using IR and Sd, respectively. CONCLUSION: This study showed an average dose reduction between 27% and 70% for the new Stellar detector, which is equivalent to using IR instead of FBP. | Andreas Christe Johannes Heverhagen Christoph Ozdoba Christian Weisstanner Stefan Ulzheimer Lukas Ebner | 2013 | World Journal of Radiology2013,5,11: | 10 |
| 3 | 转诊类型学和驱动力辨析显示文摘分析和讨论转诊的定义、内涵和相关因素是确定转诊行为的评价指标及确定转诊管理和政策的重要前提。本文把转诊行为根据行为的客体划分为使用者转诊和提供者转诊,并讨论了各种转诊行为的驱动力。任何医疗服务行为及其管理制度均建立在对激励行为的理解上。政府如欲推动双向转诊制度向健康的方向发展,应该对各种转诊行为的驱动力和阻力予以深刻的理解,并采用适宜的政策措施培育适宜转诊的驱动力,减少适宜转诊的阻力。 | 杨辉 Christ Anderson Shane Tomas | 2006 | 中国全科医学2006,9,22: | 10 |
| 4 | 一种亚稳β钛合金中疲劳短裂纹穿晶扩展晶体学特征的EBSD研究显示文摘简单介绍一种疲劳短裂纹扩展跨越晶界的晶体学模型和利用EBSD技术判定活动滑移系的简便方法.作为实际应用的示例,利用EBSD技术应用晶体学模型研究了一种亚稳β钛合金--TIMETAL LCB中疲劳短裂纹穿晶扩展的晶体学特征.实现了穿晶裂纹活动滑移系的判定.结果表明:除在试样表面晶粒两侧的裂纹走向偏折因素外,裂纹面(活动滑移面)间角是更重要的控制短裂纹穿晶扩展的晶体学因素. | 雷家峰 刘羽寅 杨锐 李东 Hans-Jūrgen Christ | 2002 | 金属学报2002,38,z1: | 10 |
| 5 | The lncRNA APOLO interacts with the transcription factor WRKY42 to trigger root hair cell expansion in response to cold显示文摘Plant long noncoding RNAs(lncRNAs)have emerged as important regulators of chromatin dynamics,impacting on transcriptional programs leading to different developmental outputs.The lncRNA AUXIN-REGULATED PROMOTER LOOP(APOLO)directly recognizes multiple independent loci across the Arabidopsis genome and modulates their three-dimensional chromatin conformation,leading to transcriptional shifts.Here,we show that APOLO recognizes the locus encoding the root hair(RH)master regulator ROOT HAIR DEFECTIVE 6(RHD6)and controls RHD6 transcriptional activity,leading to cold-enhanced RH elongation through the consequent activation of the transcription factor gene RHD6-like RSL4.Furthermore,we demonstrate that APOLO interacts with the transcription factor WRKY42 and modulates its binding to the RHD6 promoter.WRKY42 is required for the activation of RHD6 by low temperatures and WRKY42 deregulation impairs cold-induced RH expansion.Collectively,our results indicate that a novel ribonucleoprotein complex with APOLO and WRKY42 forms a regulatory hub to activate RHD6 by shaping its epigenetic environment and integrate signals governing RH growth and development. | Michael Moison Javier Martinez Pacheco Leandro Lucero Camille Fonouni-Farde Johan Rodriguez-Melo Natanael Mansilla Aurelie Christ Jeremie Bazin Moussa Benhamed Fernando Ibanez Martin Crespi Jose M.Estevez Federico Ariel | 2021 | Molecular Plant2021,14,6: | 8 |
