1BAYQIK~——高浓度二氧化硫烟气制酸创新工艺显示文摘介绍拜耳技术服务公司开发的准等温接触高浓度二氧化硫烟气制酸创新工艺BAYQIK。详述该工艺的理论基础、反应器结构、模型建立、中间试验以及在铅冶炼烟气制酸装置中的应用。BAYQIK艺的特点在于采用列管式固定床反应器,传统钒催化剂装在管内,冷却介质在壳程流动。氧化过程放出的热量被连续移走,从而使催化剂始终处于可承受的最高温度以下,即使反应器进气φ(SO2)超过50%。BAYQIK工艺可提供各种经济和工艺优点,包括可降低投资与操作成本,对于新建装置和扩能改造项目同样适用。T.

2Diagnostic value of whole-body MRI with diffusion-weighted sequence for detection of peritoneal metastases in colorectal malignancy显示文摘Objective:To assess the diagnostic accuracy of whole-body MRI using diffusion-weighted sequence(WB-DWI)to determine the peritoneal cancer index(PCI)in correlation with surgical and histopathological findings.Methods:Twenty-seven patients underwent preoperative WB-MRI,followed by cytoreductive surgery for primary tumors of the appendix(n=15),colorectum(n=12),and associated peritoneal disease.A total of 351 regions were retrospectively reviewed.The sensitivity,specificity,and accuracy were calculated at 13 anatomical sites.The WB-DWI PCI and PCI type were compared with surgical and histopathological findings.Results:No statistical difference was found between the WB-DWI PCI and surgical PCI(P=0.574).WB-DWI correctly predicted the PCI type in 24 of 27 patients with high accuracy(88.9%),including 10 of 10 patients with small-volume tumor,12 of 14 with moderate-volume tumor,and 2 of 3 with large-volume tumor.WB-DWI correctly depicted tumors in 163 of 203 regions,with 40false-negative and 23 false-positive regions.The overall sensitivity,specificity,and accuracy of WB-DWI for the detection of peritoneal tumors were 80.3%,84.5%,and 82.1%,respectively.For lesions<0.5 cm in diameter,WB-DWI demonstrated good sensitivity(69.4%).Conclusions:WB-DWI accurately predicted PCI before surgery in patients undergoing evaluation for cytoreductive surgery.Huan Zhang Weixing Dai Caixia Fu Xu Yan Alto Stemmer Tong Tong Guoxiang Cai 2018Cancer Biology & Medicine2018,15,2:3

5Molecular architecture of mouse and human pancreatic zymogen granules: protein components and their copy numbers显示文摘A molecular model of pancreatic zymogen granule (ZG) is critical for understanding its functions. We haveextensively characterized the composition and membrane topology of rat ZG proteins. In this study, wereport the development of targeted proteomics approaches to quantify representative mouse and humanZG proteins using LC-SRM and heavy isotope-labeled synthetic peptides. The absolute quantities of mouseRab3D and VAMP8 were determined as 1242 ± 218 and 2039±151 (mean ± SEM) copies per ZG. Thesize distribution and the averaged diameter of ZGs 750 ±23 nm (mean ± SEM) were determined byatomic force microscopy. The absolute quantification of Rab3 D was then validated using semi-quantitativeWestern blotting with purified GST-Rab3D proteins as an internal standard. To extend our proteomicsanalysis to human pancreas, ZGs were purified using human acini obtained from pancreatic islet trans-plantation center. One hundred and eighty human ZG proteins were identified for the first time includingboth the membrane and the content proteins. Furthermore, the copy number per ZG of human Rab3 D andVAMP8 were determined to be 1182 ± 45 and 485 ± 15 (mean ± SEM). The comprehensive proteomicanalyses of mouse and human pancreatic ZGs have the potential to identify species-specific ZG proteins.The determination of protein copy numbers on pancreatic ZGs represents a significant advance towardsbuilding a quantitative molecular model of a prototypical secretory vesicle using targeted proteomicsapproaches. The identification of human ZG proteins lays a foundation for subsequent studies of altered ZGcompositions and secretion in pancreatic diseases.Jin-sook Lee Joseph A.
