Mitochondrial monoamine oxidase (MAO) was found in human semen, showing its Km and Vmax values of 91.7 microM and 290 pmoles/mg of protein/60 min, respectively, with kynuramine as substrate. A major part of the activity was due to type A MAO. 相似文献

Synephrine (SP) was found to be a substrate for monoamine oxidase (MAO) in rat brain mitochondria, showing the Km and Vmax values of 250 microM and 32.6 nmoles/mg of protein/30 min respectively. The inhibition studies showed that the SP oxidation was carried out by both type A and type B MAO and a major part of the activity was due to type A MAO. 相似文献

Frequent somatic mutations in PTEN and TP53 are mutually exclusive in the stroma of breast carcinomas 总被引:19,自引:0,他引:19
We have recently shown that loss of heterozygosity of specific markers, including those at 10q23, 17p13-p15 and 16q24, can occur in the stromal and epithelial compartments of primary invasive breast carcinomas. Here, we demonstrate high frequencies of somatic mutations in TP53 (encoding tumor protein p53) and PTEN (encoding phosphate and tensin homolog) in breast neoplastic epithelium and stroma. Mutations in TP53 and PTEN are mutually exclusive in either compartment. In contrast, mutations in WFDC1 (16q24, encoding WAP four-disulfide core domain 1) occur with low frequency in the stroma. 相似文献

线虫表被层在寄主寄生者互作中起着多种关键作用。几种凝集素在不同虫龄的表被层中的结合能力测定证明,麦胚凝集素(WGA)仅结合到3龄繁殖幼虫及卵壳表面,但这种结合经常发生在毒性松材线虫分离物中,而不是低毒松材线虫分离物的表被层。卵壳表面WGA的结合最强。WGA经常结合到线虫表被层上。表被层蛋白提取物的分析显示其碳氢化合物及蛋白质谱随线虫发育和对松树寄主的入侵而变化。研究结果表明,松材线虫的表被层蛋白在松树寄主和线虫间的互作中起着重要作用。 相似文献

Summary Monoacetylcadaverine and monopropionylcadaverine were found to be substrates for both rat liver monoamine oxidase and hog kidney diamine oxidase, but all the Km-values for the oxidases were very high. The amines were common substrates for type A and type B monoamine oxidase. 相似文献

This paper represents a design and development of a mobile sensing unit as well as its prototype implementation for railway track monitoring. The unit consists of an ultra-small personal computer (PC), a global positioning system (GPS) receiver, an accelerometer and an ADC (Analog/Digital Converter) so that the unit can trace the route while capturing an acceleration response of a passenger vehicle. The unit enables more frequent and qualitative data acquisition compared with traditional and the state of the practice railway track inspection equipments. Locating disorder is the key of our unit, which has a reasonable accuracy of positioning with GPS data, existing facilities landmarks, and car acceleration responses. The proposed unit is a promising device for efficient properties management of railway agencies. The prototype implementation shows a result that car acceleration responses are related with the track displacements in low frequencies. The results also imply that sensor settlement on a vehicle floor, not axes or bogies, is effective for capturing track vertical displacements. 相似文献

探讨了北九州市新规划热供给区域的热电并给系统导入效果.根据东京的能源消费功能单位,推测了北九州市的能源消费功能单位.利用不同建筑用途的建筑面积和能源消费功能单位,计算了北九州市新规划热供给区域的能源需要量、设定了单体空调系统、锅炉系统、电主热从及热主电从的热电并给系统等4种能源供给系统,并计算了各系统的能源消费量、二氧化碳排放量、初期投资、运行费用和单纯回收年数、计算结果表明,综合考虑能源消费量、二氧化碳排放量和运行费用,新规划热供给区域导入能源供给系统时,热电并给系统是最好的选择. 相似文献
