1Targeted therapy for advanced gastric cancer: A review of current status and future prospects显示文摘In the West in particular, the vast majority of gastric cancer(GC) patients present with advanced-stage disease. Although combination chemotherapy is stillthe most important component of treatment for these patients, it confers a modest survival advantage. Recently, increased knowledge of the key molecular signaling pathways involved in gastric carcinogenesis has led to the discovery of specific molecular-targeted therapeutic agents. Some of these agents such as trastuzumab and ramucirumab have changed the treatment paradigm for this disease. In this paper, we will summarize the current clinical status of targeted drug therapy in the management of GC.Ozkan Kanat Bert O'Neil Safi Shahda 2015World Journal of Gastrointestinal Oncology2015,7,12:13
2强化MBR处理含酚毒性废水及膜过滤特性的研究显示文摘考察添加白腐菌的生物强化膜生物反应器(EMBR)对含酚毒性废水的强化处理效果及其对膜过滤特性的影响.在优化工艺条件下,T=25℃,pH=6.5,水力停留时间(HRT)=10 h,菌种采用粒状活性炭(GAC)负载形式,进水TOC(总有机碳)容积负荷从0.96 kg/(m3.d)增至2.4 kg/(m3.d).实验结果表明:EMBR比传统膜生物反应器(CMBR)处理废水效果更佳(TOC平均去除超过90%),且在研究范围内负荷越高强化处理效果越显著,表明EMBR工艺具有更强的耐负荷冲击及抗毒性.此外,EMBR具有更高的临界通量[20.6 L/(m2.h)],膜持续运行时间更长,且膜污染速率及不可逆内部膜污染阻力均比CMBR有明显降低,表明其在改善膜污染方面亦具有优势.周颖 许振良 陈桂娥 卢琼 Munib Shahda 2009膜科学与技术2009,29,3:2
3Studies on Catalyst Deactivation Rate and Byproducts Yield during Conversion of Methanol to Olefins显示文摘The conversion of methanol to olefins (MTO) over the SAPO-34 catalyst in fixed-bed microreactor was studied. The effect of reaction temperatures for methanol conversion to olefins and byproducts was investigated. A temperature of 425 ℃ appeared to be the optimum one suitable for conversion of methanol to olefins. Since the presence of water could increase the olefins selectivity, the methanol conversion reactions with mixed water/methanol feed were also studied. The effect of weight hourly space velocity on conversion of methanol was also studied. The results indicated that the olefins selectivity was significantly increased as WHSV increased till approximately 7.69 h-1 then it began to level off. Different factors affecting the catalyst deactivation rate was studied, showing that the catalyst deactivation time was dependent on reaction conditions, and temperatures higher and lower than the optimal one made the catalyst deactivation faster. Adding water to methanol could slow down the catalyst deactivation rate.Munib Shahda 2006China Petroleum Processing & Petrochemical Technology2006,8,3:1

5Study on Olefins Yield from Methanol Conversion over Different Catalysts显示文摘Conversion of Methanol to Olefins (MTO) under different reaction conditions was ex- perimentally investigated over different catalysts, and comparison was made between the SAPO-34 and GOR-MLC catalysts. Optimization of reaction conditions has been explored. Conversion of methanol to olefins over these catalysts under different reaction temperatures was experimentally studied. In a fixed bed micro-reactor, the influence of temperature was found to be one of the major factors. For both catalysts the olefins yield was increased significantly when water was added to the methanol feed. A temperature range of 460—480 ℃ appeared to be the optimum range suitable for methanol conversion with appropriate catalyst activity and C2—C3 olefins yield. Some other hydrocarbons appeared during the MTO reaction in the presence of the SAPO-34 catalyst, while a lot of dimethylether was formed when the GOR-MLC catalyst was used. In the course of the MTO reaction, the GOR-MLC catalyst was found to have a faster catalyst deactivation rate compared to the SAPO-34 catalyst.Munib Shahda 2006China Petroleum Processing & Petrochemical Technology2006,8,1:1

9满足不同工况的控制阀解决方案梅索尼兰Lincolnlong控制阀在高压锅炉给水中的应用显示文摘高压锅炉给水控制系统,即主锅炉给水系统,是电厂控制阀应用中最关键也是最富挑战性的部分之一。锅炉给水系统调节汽包水位,从而决定锅炉产生的蒸汽量,再经发电机输出,电能由此而来。控制阀的解决方案需要根据系统的应用来适当选择,性能上细微的差别都可能会对发电机的发电过程产生重大影响。本文对比了两种不同的锅炉给水系统设计以及各自的相关问题,并对梅索尼兰的控制阀解决方案加以介绍。Joseph Shahda 2006流程工业2006,,10:0
