1role of microRNAs in the main molecular pathways of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the most common primary liver malignant neoplasia. HCC is characterized by a poor prognosis. The need to find new molecular markers for its diagnosis and prognosis has led to a progressive increase in the number of scientific studies on this topic. MicroRNAs(miRNAs) are small noncoding RNA that play a role in almost all main cellular pathways. miRNAs are involved in the regulation of expression of the major tumor-related genes in carcinogenesis, acting as oncogenes or tumor suppressor genes. The aim of this review was to identify papers published in 2017 investigating the role of miRNAs in HCC tumorigenesis. miRNAs were classified according to their role in the main molecular pathways involved in HCC tumorigenesis:(1) m TOR;(2) Wnt;(3) JAK/STAT;(4) apoptosis; and(5) MAPK. The role of miRNAs in prognosis/response prediction was taken into consideration. Bearing in mind that the analysis of miRNAs in serum and other body fluids would be crucial for clinical management, the role of circulating miRNAs in HCC patients was also investigated. The most represented mi RNA-regulated pathway in HCC is m TOR, but apoptosis, Wnt, JAK/STAT or MAPK pathways are also influenced by mi RNA expression levels. These miRNAs could thus be used in clinical practice as diagnostic, prognostic or therapeutic targets for HCC treatment.Francesco Vasuri Michela Visani Giorgia Acquaviva Thomas Brand Michelangelo Fiorentino Annalisa Pession Giovanni Tallini Antonia D’Errico Dario de Biase 2018World Journal of Gastroenterology2018,24,25:16
2Dietary and metabolomic determinants of relapse in ulcerative colitis patients: A pilot prospective cohort study显示文摘AIM To identify demographic, clinical, metabolomic, and lifestyle related predictors of relapse in adult ulcerative colitis(UC) patients.METHODS In this prospective pilot study, UC patients in clinical remission were recruited and followed-up at 12 mo to assess a clinical relapse, or not. At baseline information on demographic and clinical parameters was collected. Serum and urine samples were collected for analysis of metabolomic assays using a combined direct infusion/liquid chromatography tandem mass spectrometry and nuclear magnetic resolution spectroscopy. Stool samples were also collected to measure fecal calprotectin(FCP). Dietary assessment was performed using a validated self-administered food frequency questionnaire. RESULTS Twenty patients were included(mean age: 42.7 ± 14.8 years, females: 55%). Seven patients(35%) experienced a clinical relapse during the follow-up period. While 6 patients(66.7%) with normal body weight developed a clinical relapse, 1 UC patient(9.1%) who was overweight/obese relapsed during the follow-up(P = 0.02). At baseline, poultry intake was significantly higher in patients who were still in remission during follow-up(0.9 oz vs 0.2 oz, P = 0.002). Five patients(71.4%) with FCP > 150 μg/g and 2 patients(15.4%) with normal FCP(≤ 150 μg/g) at baseline relapsed during the follow-up(P = 0.02). Interestingly, baseline urinary and serum metabolomic profiling of UC patients with or without clinical relapse within 12 mo showed a significant difference. The most important metabolites that were responsible for this discrimination were trans-aconitate, cystine and acetamide in urine, and 3-hydroxybutyrate, acetoacetate and acetone in serum. CONCLUSION A combination of baseline dietary intake, fecal calprotectin, and metabolomic factors are associated with risk of UC clinical relapse within 12 mo.Ammar Hassanzadeh Keshtel iFloris F van den Brand Karen L Madsen Rupasri Mandal Rosica ValchevaKaren I Kroeker Beomsoo Han Rhonda C Bell Janis Cole Thomas Hoevers David S Wishart Richard N Fedorak Levinus A Dieleman 2017World Journal of Gastroenterology2017,23,21:9
3对敏感型电子的信号输入实施过压保护之可靠新方法显示文摘由于对电子系统可靠性的高要求,特别是在工业环境中,不断给开发人员带来巨大的挑战。其中,过压保护是一个关键的设计考量因素和挑战,鉴于要保护系统不受过压影响通常需要用到更多部件,而这些附加部件经常会对系统产生影响,在最坏的情况下,甚至会产生错误信号。除此之外,这些部件会额外增加成本,还会进一步加重空间限制问题。因此,在设计保护电路时,传统的解决方案往往需要在系统精度和保护等级之间做出妥协。Thomas Brand 2019中国集成电路2019,28,11:3

7适合高精度测量应用的完全集成式4线RTD温度测量系统的简单实现显示文摘对于各种各样的产品,制造过程需要高度精确和可靠的温度测量技术。通常通过与传感器直接接触来测量温度,例如通过将传感器浸入到液体中或通过与机器的表面接触来测量温度。除热敏电阻和热电偶之外,由于其快速响应时间和高达几百μV/℃的出色灵敏度,电阻温度检测器(RTD)尤其适用。它们也可用于-200℃至+800℃超宽范围内的测量,且具有近线性行为。RTD提供多种版本,例如2线、3线或4线版本,且具有高度应用灵活性。Thomas Brand 2019中国集成电路2019,28,12:1

11Intraprosthetic fixation techniques in the treatment of periprosthetic fractures: A biomechanical study显示文摘AIM: To develop new fixation techniques for the treatment of periprosthetic fractures using intraprosthetic screw fixation with inserted threaded liners. METHODS: A Vancouver B1 periprosthetic fracture was simulated in femur prosthesis constructs using sawbones and cemented regular straight hip stems. Fixation was then performed with either unicortical locked-screw plating using the less invasive stabilization system-plate or with intraprosthetic screw fixation using inserted liners. Two experimental groups were formed using either prostheses made of titanium alloy or prostheses made of cobalt chrome alloy. Fixation stability was compared in an axial load-to-failure model. Drilling was performed using a specially invented prosthesis drill with constantly applied internal cooling.RESULTS: The intraprosthetic fixation model with titanium prostheses was superior to the unicortical lockedscrew fixation in all tested devices. The intraprosthetic fixation model required 10 456 N ± 1892 N for failure and the unicortical locked-screw plating required 7649 N ± 653 N(P < 0.05). There was no significant difference between the second experimental group and the control group.CONCLUSION: Intraprosthetic screw anchorage with special threaded liners enhances the primary stability in treating periprosthetic fractures by internal fixation.Stephan Brand Johannes Klotz Thomas Hassel Maximilian Petri Carl Haasper Friedrich-Wilhelm Bach Christian Krettek Thomas Goesling 2012World Journal of Orthopedics2012,3,10:1

14运算放大器的串联:如何同时实现高精度和高输出功率显示文摘工程师常常面对各种挑战,需要不断开发新应用,以满足广泛的需求。一般来说,这些需求很难同时满足。例如一款高速、高压运算放大器(运放),同时还具有高输出功率,以及同样出色的直流精度、噪声和失真性能。市面上很少能见到兼具所有这些特性的运算放大器。但是,您可以使用2个单独的放大器来构建这种放大器,形成复合放大器。将2个运算放大器组合在一起,就能将各自的优势特性集成于一体。这样,与具有相同增益的单个放大器相比,2个运算放大器组合可以实现更高的带宽。Thomas Brand 2020电子产品世界2020,27,10:1

16OPC UA和TSN-未来的公共语言显示文摘目前的两个关键术语主导了涉及工业通信主题的讨论:时间敏感网络(即:TSN)以及OPC UA。TSN是IEEE 802.1行业标准的一组扩展,使得以太网通信能够满足实时要求,而无需将来进行特殊扩展。通过将这些新的以太网功能与行业范围的OPC UA标准结合起来,似乎有可能形成不同制造商的设备之间交换数据的一种公共语言。Thomas Brand 王锡俊(译) 2018国内外机电一体化技术2018,0,4:1
