| 1 | 前瞻性和回顾性心电门控冠状动脉64层CT成像:影像质量和病人放射剂量的对照性研究显示文摘目的比较一组接受前瞻性心电门控64层CT冠状动脉成像病人及另一组接受回顾性心电门控64层CT冠状动脉病人的成像质量及病人放射剂量。方法本研究依从HIPAA法案并得到了机构审查委员会的批准。由于设计是回顾性研究故不需要知情同意。2位独立阅片者分别对100例病人心脏CT成像(每组各50例)的冠状动脉进行分段影像质量评分和综合评分。计算观察者间偏差。记录对应实际扫描Z轴长度的病人放射剂量,以Z轴长度为12cm的典型心脏计算标准化剂量。结果2组病例的临床特征及CT参数匹配良好。 | W.P.

| 2 | 以便秘和腹泻为主的肠易激综合征与5-羟色胺信号改变显示文摘Background &Aims: Evidence suggests that postprandial platelet-depleted plasma 5-hydroxytryptamine (5-HT) concentrations may be abnormal in irritable bowel syndrome (IBS). However, interpretation of the data has been hampered by the variable methodology and rather small numbers used in previous studies. Therefore, the aim of this study was to measure concentrations of platelet-depleted plasma 5-HT and its metabolite 5-HIAA under fasting and fed conditions in a large group of patients with diarrhea-predominant (d-) and constipation-predominant (c-) IBS, compared with controls. The ratio of plasma 5-HIAA:5-HT and platelet stores was also assessed. Methods: Twenty-nine c-IBS patients (aged, 19-53 years), 55 d-IBS patients (aged, 19-52 years), and 35 healthy volunteers (aged, 18-46 years) had platelet-depleted plasma 5-HT/5-HIAA concentrations measured using reverse-phase, high-performance liquid chromatography with fluorimetric detection before and after a standard meal. Results: d-IBS patients had raised platelet-depleted plasma 5-HT concentrations under fasting and fed conditions (P < .05). However, the postprandial relative to fasting concentration was similar to controls. In contrast, c-IBS patients failed to show an increase in platelet-depleted plasma 5-HT concentration with meal ingestion compared with controls (P < .01). c-IBS was associated with decreased 5-HIAA (P < .01) but normal 5-HIAA:5-HT ratio and d-IBS with normal 5-HIAA concentrations but reduced 5-HIAA:5-HT ratio (P < .005). c-IBS but not d-IBS patients had increased platelet 5-HT. Conclusions: These results support the concept that d-IBS is characterized by reduced 5-HT reuptake, whereas impaired release may be a feature of c-IBS. These results also provide a rational basis for current pharmacologic approaches involving modulation of different 5-HT receptors in c-and d-IBS. | Atkinson W. Lockhart S. Whorwell P. J. L.A.

| 3 | A Perspective on Smart Process Manufacturing Research Challenges forProcess Systems Engineers显示文摘The challenges posed by smart manufacturing for the process industries and for process systems engineering(PSE) researchers are discussed in this article. Much progress has been made in achieving plant- and site-wide optimization, hut benchmarking would give greater confidence. Technical challenges confrontingprocess systems engineers in developing enabling tools and techniques are discussed regarding flexibilityand uncertainty, responsiveness and agility, robustness and security, the prediction of mixture propertiesand function, and new modeling and mathematics paradigms. Exploiting intelligence from big data to driveagility will require tackling new challenges, such as how to ensure the consistency and confidentiality ofdata through long and complex supply chains. Modeling challenges also exist, and involve ensuring that allkey aspects are properly modeled, particularly where health, safety, and environmental concerns requireaccurate predictions of small but critical amounts at specific locations. Environmental concerns will requireus to keep a closer track on all molecular species so that they are optimally used to create sustainablesolutions. Disruptive business models may result, particularly from new personalized products, but that isdifficult to predict. | Ian David Lockhart Bogle | 2017 | Engineering2017,3,2: | 7 |
