1西藏羊八井热田地热流体成因及演化的惰性气体制约显示文摘地热流体中惰性气体的相对丰度和同位素组成 ,不仅可以揭露热田的热源性质 ,而且还能够揭示深、浅层地热流体的内在联系和演化过程等。在西藏羊八井热田的地热气体中 ,已检测出大量的 4 He组分 ,3He/ 4 He值是大气的 0 .0 87~ 0 .2 5 9倍 ,表明深部地壳物质的局部熔融为热田提供能量。浅层地热流体的 3He/ 4 He值自西北向东南呈降低趋势 ,与热储温度的变化相一致 ,反映出侧向运移时补充了更多的壳源氦。热田北区深层地热流体具有稍高的 3He/ 4 He值 ,是浅层地热流体的母源。气体中氪和氙的相对丰度具有大气降水成因的特征。结合现有的实际资料 。赵平 Mack KENNEDY 多吉 谢鄂军 杜少平 David SHUSTER 金建 2001岩石学报2001,17,3:24
2Predisposing factors for positive D-Xylose breath test for evaluation of small intestinal bacterial overgrowth:A retrospective study of 932 patients显示文摘AIM: To investigate, in the largest cohort to date, patient characteristics and associated risk factors for developing small intestinal bacterial overgrowth(SIBO) using the D-Xylose breath test(XBT).METHODS: We performed a retrospective crosssectional study to analyze patient characteristics who underwent the XBT for evaluation of SIBO. Diagnostic testing with the XBT was performed based on a clinical suspicion for SIBO in patients with symptoms of bloating, abdominal pain, abdominal distension, weight loss, diarrhea, and/or constipation. Consecutive electronicmedical records of 932 patients who completed the XBT at the University of Florida between 2005 and 2009 were reviewed. A two-way Analysis of Variance(ANOVA) was used to test for several associations including age, gender, and body mass index(BMI) with a +XBT. A two-way ANOVA was also performed to control for the differences and interaction with age and between genders. A similar analysis was repeated for BMI. Associations between medical conditions and prior surgical histories were conducted using the Mantel-Haenszel method for 2 by 2 contingency tables, stratified for gender. Reported odds ratio estimates reflect the odds of the prevalence of a condition within the +XBT group to that of the-XBT group. P values of less than 0.05(two-sided) were considered statistically significant.RESULTS: In the 932 consecutive eligible subjects studied, 513 had a positive XBT. A positive association was found between female gender and a positive XBT(P = 0.0025), and females with a positive test were, on average, greater than 5 years older than those with a negative test(P = 0.024). The mean BMI of positive XBT subjects was normal(24.5) and significantly lower than the subjects with a negative XBT(29.5)(P = 0.0050). A positive XBT was associated with gastroesophageal reflux disease(GERD)(OR = 1.35; 95%CI: 1.02-1.80, P = 0.04), peptic ulcer disease(PUD)(OR = 2.61; 95%CI: 1.48-4.59, P < 0.01), gastroparesis(GP)(OR = 2.04; 95%CI: 1.21-3.41, P < 0.01) and steroid use(OR = 1.35; 95%CI: 1.02-1.80, P = 0.01). Irritable bowel syndrome, independent protonpump inhibitor(PPI) usage, or previous abdominal surgery was not significantly associated with a positive XBT. No single subdivision by gender or PPI use was associated with a significant difference in the odds ratios between any of the subsets. CONCLUSION: Female gender, lower BMI, steroid use, PUD, GERD(independent of PPI use), and GP were more prevalent in patients with SIBO, determined by a positive XBT. Increasing age was associated with SIBO in females, but not in males.Richard A Schatz Qing Zhang Nilesh Lodhia Jonathan Shuster Phillip P Toskes Baharak Moshiree 2015World Journal of Gastroenterology2015,21,15:4
3活塞环、气缸套拉缸现象的调研、模拟和预防显示文摘活塞环外圆面和气缸套之间的拉缸是一个极难预测、难于重现但会导致发动机性能下降的现象。讨论在现场使用、发动机试验和台架试验后,硬质和软质气缸套与不同活塞环复层之间发生拉缸的冶金学和计量学(事后分析)检查的结果。详细的冶金学分析描述了不同温度和有、无润滑油条件下,各种活塞环复层和铸铁气缸套之间的润滑机理。叙述在上止点处,由于润滑剂缺乏或不足造成拉缸的原因,特别是强载柴油机硬化的铸铁气缸套。用Falex和LS9试验机进行试验室试验时,拉缸原因和随后的严重粘着磨损机理是通过摩擦系数和辐射噪声的测量来评定的。为了模拟现场使用和试验室快速试验后,活塞环和气缸套间相同的拉缸机理,开发了专用的试验研究法和测量技术。提供来自传统的和新型活塞环复层对硬质和软质气缸套,在不同温度、有或无润滑油情况下的摩擦学试验数据。最后介绍一种减少拉缸现象出现的活塞环新型复层。Shuster MM Stong T Deis MC 薛景渊 2000国外内燃机2000,32,3:4
4“双盲、安慰剂对照交叉设计研究植物药对于进食量、饱腹感、体重减轻及氧化应激的影响”的研究方案(英文)显示文摘背景:植物性治疗药物作为一种重要且尚未被完全开发的药用资源,可能有助于热量控制从而产生长期的减重功效。从藤黄果(Garcinia combogia Desr.)中提取的羟基柠檬酸可能通过影响与饱腹有关的神经通路而减少摄食量和减轻体重。方法与设计:本研究为双盲、安慰剂对照、交叉设计试验,共计划纳入48名超重或肥胖的健康受试者(体重指数25.0~39.9 kg/m^2,年龄50~70岁),研究两种剂量藤黄果来源的羟基柠檬酸对摄食量、饱腹感、体重减轻及氧化应激水平的影响。摄食量作为主要结局指标,根据受试者在测量日的早餐、午餐和晚餐的摄食量计算。与平行设计的研究相比,本研究所使用的受试者数量将大大减少。讨论:本研究选择藤黄果来源的羟基柠檬酸为研究对象是因为该药物能够安全地减少摄食量、减轻体重和降低氧化应激水平。我们将会在研究过程中探讨其可能的作用机制和安全指标。Stephen D.Anton Jonathan Shuster Christiaan Leeuwenburgh 2011中西医结合学报2011,9,11:2
