Prognostic factors for survival after neoadjuvant chemotherapy for advanced ovarian cancer: meta-analysis

引用

Open Journal of Obstetrics and Gynecology 2011年第3期1卷 71-83页

作者： Malcolm John Farquharson Nadeem ahmed siddiqui 不详

Background: In advanced disease current practice is staging and primary debulking laparotomy followed by platinum-based chemotherapy. The effort to achieve ‘optimal debulking’ is associated with a complication risk of 8% - 63% and a mortality rate of 1% - 6%. Neoadjuvant chemotherapy has been proposed as an alternative option. Objectives: This meta-analysis aimed to determine prognostic factors influencing survival in patients with advanced ovarian cancer following neoadjuvant chemotherapy. Search Strategy: Clinical trials citing the terms ‘advanced ovarian cancer’, ‘ovarian cancer’, ‘neoadjuvant chemotherapy’ and ‘surgery’ were identified by searching Pubmed and ScienceDirect between January 1st 2000 and September 30th 2010. Data Collection and analysis: The trials included used platinum-based chemotherapy and involved stage III/IV disease that underwent neoadjuvant chemotherapy followed by surgery. Prognostic variables were identified for analysis including number/type of chemotherapy, % stage IV disease, % maximal cytoreductive surgery and whether a lymphadenectomy was performed. The % bowel surgery and ultra-radical surgery was also analysed. Main Results: Twenty six trials were identified as suitable for analysis and included 3 non-randomised Phase II studies, 2 retrospective case-control studies, 17 from retrospective analysis and 1 RCT. A significant association between taxane use vs platinum only (p = 0.019), year of publication (p = 0.032), % maximal interval cytoreduction (p = 0.046) and median overall survival was identified. No significant survival benefit was demonstrated with number of chemotherapy cycles (p = 0.065), lymphadenectomy (p = 0.813) and % bowel surgery performed (p = 0.606). Conclusions: The addition of taxane and % maximal cytoreduction achieved is associated with improved overall survival. There is, however no evidence that lymphadenectomy, number of chemotherapy cycles or bowel surgery influences survival.

巴基斯坦和沙特阿拉伯关系密切,它们在宗教,政治,战略,文化和经济方面都有联系。本研究旨在分析1990年至2019年间两国之间的双边商贸关系及其利弊。贸易在主权国家关系中目前处于非常重要的地位,因此所有国家都非常重视建立互利互惠的商贸关系。巴基斯坦和沙特阿拉伯自1960年代起就建立了商贸关系,但自1990年以来,由于两国政治关系更加牢固,以及巴基斯坦采用了自由化的贸易政策的缘故,两国的贸易得到了极大改善,并互惠互利。沙特阿拉伯和巴基斯坦历届领导人都定期访问对方,这使两国之间的关系和相互了解更加深入。现在,经济事务和贸易是两国关系的主要内容。这项研究详细探讨和分析了巴基斯坦和沙特阿拉伯的商贸关系,并提出了关于新的合作机会,合作的潜在领域,以及如何加强现有的贸易水平的建议。目前,两国每年的双边贸易额超过40亿美元。巴基斯坦向沙特阿拉伯出口各种商品,包括大米,纱织品,棉花,成衣,毛衣,毛巾,纤维制品,沙发亚麻,芒果,遮蔽物,艺术肖像,丝绸,人造物品,家具,皮革服装,地板,鞋类,地毯,医疗设备,体育用品,鱼类,不同种类的水果,不同种类的蔬菜,调味料和不同种类的果汁等等。巴基斯坦从沙特阿拉伯进口的商品主要包括石油,塑料,有机化学制品,皮革,铝,钢铁等。两国也建立了一系列机构和组织来管理并促进两国贸易。自1970年以来,巴基斯坦沙特联合部长级委员会(PSJM)成为解决所有双边贸易和贸易问题的最高机构。PSJM有望达成使巴基斯坦将来成为沙特阿拉伯良好合作伙伴的目标。同时,沙特阿拉伯也成立了伊斯兰公司组织(OIC)。沙特阿拉伯常常以经济援助的形式对巴基斯坦提供帮助。例如,沙特阿拉伯以石油形式提供的大量经济援助。在战争或自然灾害时期,沙特还往往扩大对巴基斯坦的援助。在国际议题上,石油进出口以一种经济形式来满足两国军事和政治利益,并对两国关系产生重要影响。沙特阿拉伯是石油丰富的国家。巴基斯坦可以通过进口石油来满足其需求。沙特总是在不同场合向巴基斯坦提供石油。沙特阿拉伯在海湾合作委员会国家中是巴基斯坦第二大商品进口国。从2007年到2012年,巴基斯坦对沙特阿拉伯王国的出口总额徘徊在5亿美元左右。但到2012年,它已经是沙特第二大进口伙伴,据沙特阿拉伯贸易部长介绍,两国之间的贸易额在2012年约为48亿美元。像其他中东国家一样,沙特阿拉伯致力于投资其他国家的农业部门,以解决他们的粮食不安全问题,并且通过向伊斯兰堡提供十亿美元的一揽子援助,该国最近已经获得了数千英亩的土地用于在巴基斯坦耕种。这可能会满足海湾国家的粮食需求。但是两国商贸关系依然面临着国内、国际层面的诸多问题。沙特阿拉伯王国有许多出口伙伴。巴基斯坦则主要向沙特阿拉伯出口各种商品。两国贸易关系体现出较强的不平衡性。因此,巴基斯坦应该专注于开发新的具有潜力的产品。由于当前的经济和政治气候,巴基斯坦的出口市场利润丰厚。巴基斯坦与沙特阿拉伯的经济关系必须改善和深化。沙特阿拉伯和巴基斯坦的地理环境不尽相同,但是历史悠久的贸易往来和宗教背景却很亲密,但由于许多潜在的内部和外部挑战,包括诸如宗教派别差异,两国之间有水陆间隔等。为了进一步改善巴基斯坦和沙特的双边贸易关系并消除挑战,本研究提出了一些建议:启用理事会,以优化贸易机会并建立新的伙伴关系;两国的私营部门应定期开会分享信息,并与同行的贸易商会面。定期进行辅助性商业活动,例如开办交易会和展览,组织商业会议以及互派贸易代表团,这些有助于更好地了解彼此的市场;通过交流市场前景信息等来扩大贸易联系;解决贸易障碍,解决法规,标准化,卫生等问题;制定政策,促进对方高需求的物品的出口;巴基斯坦可以寻求就关税减让建立一套结构化的贸易方案和协议;共同努力建立一种机制,以减少巴基斯坦向沙特阿拉伯出口农产品时面临的非关税壁垒;充分执行已签署的协议,尽早执行商定的计划。该研究旨在调查两国贸易和经济前景,以期最终利用巴基斯坦-沙特阿拉伯之间双边贸易的不同变量来促进贸易和经济的发展进步。这项研究的还意图评估两国贸易和经济发展的现状,以及在国家贸易部门进行的改变。本研究提出并回答了这一问题:为什么巴基斯坦和沙特阿拉伯需要建立贸易关系,这种双边贸易的重要意义是什么?这项研究主要运用了国际关系的自由主义理论。这一理论为牢固的经贸关系和相互合作,而不是竞争和强权政治,提供了理论支撑。巴基斯坦和沙特阿拉伯在双边贸易关系中都践行着自由主义关系理论。本研究从书籍、论文、期刊与机构数据中搜集关于1990-2019年巴基斯坦与沙特阿拉伯的贸易进出口数据,以图表形式直观展示了两国贸易关系的发展变化。本研究认为贸易具有重要意义,在经济发展中发挥着积极作用。贸易使商业边界更加紧密,生成了进一步改进贸易的未来计划,促进了企业和企业之间的贸易往来,鼓励与小企业的互动,最终促进了两国在当地和国际层面的商业

Long Range Wide Area Network (LoRaWAN) in the Internet ofThings (IoT) domain has been the subject of interest for researchers. Thereis an increasing demand to localize these IoT devices using LoRaWAN dueto the quickly growing number of IoT devices. LoRaWAN is well suited tosupport localization applications in IoTs due to its low power consumptionand long range. Multiple approaches have been proposed to solve the localizationproblem using LoRaWAN. The Expected Signal Power (ESP) basedtrilateration algorithm has the significant potential for localization becauseESP can identify the signal’s energy below the noise floor with no additionalhardware requirements and ease of implementation. This research articleoffers the technical evaluation of the trilateration technique, its efficiency,and its limitations for the localization using LoRa ESP in a large outdoorpopulated campus environment. Additionally, experimental evaluations areconducted to determine the effects of frequency hopping, outlier removal, andincreasing the number of gateways on localization accuracy. Results obtainedfrom the experiment show the importance of calculating the path loss exponentfor every frequency to circumvent the high localization error because ofthe frequency hopping, thus improving the localization performance withoutthe need of using only a single frequency.

A Novel Device for Real-Time Monitoring of High Frequency Phenomena in CENELEC PLC Band

引用

Smart Grid and Renewable Energy 2012年第2期3卷 152-157页

作者： Bashir ahmed siddiqui Pertti Pakonen Pekka Verho Department of Electrical Energy Engineering Tampere University of Technology Tampere Finland.

This paper proposes the design and development of a novel, portable and low-cost intelligent electronic device (IED) for real-time monitoring of high frequency phenomena in CENELEC PLC band. A high speed floating-point digital signal processor (DSP) along with 4 MSPS analog-to-digital converter (ADC) is used to develop the intelligent electronic device. An optimized algorithm to process the analog signal in real-time and to extract the meaningful result using signal processing techniques has been implemented on the device. A laboratory environment has setup with all the necessary equipment including the development of the load model to evaluate the performance of the IED. Smart meter and concentrator is also connected to the low voltage (LV) network to monitor the PLC communication using the IED. The device has been tested in the laboratory and it has produced very promising results for time domain as well as frequency domain analysis. Those results imply that the IED is fully capable of monitoring high frequency disturbances in CENELEC PLC band.

Mode of Occurrence and Mineralogy of Northern Khetri Copper Deposits, Jhunjhunu District, Rajasthan

引用

Natural Resources 2018年第12期9卷 389-403页

作者： masood ahmed Mohd Shaif Farhat Naseem siddiquie Rajiullah Khan Department of Geology Aligarh Muslim University Aligarh India

Copper deposits in Khetri copper belt are hosted in the proterozoic sequence of rocks belonging to Ajabgarh group of Delhi supergroup situated in foot hill zone of Aravalli mountain range North-West, India. Khetri copper belt is about 100?km long NE-SW trending metallogenic province, starting from Singhana in the north to Sangarava in the south. The study area is the northern Khetri copper belt 190 km SW of Delhi,?the capital city of India. In the present work an attempt has been made to determine the mode of occurrence and nature of mineralization with special emphasis on mineragraphic study of copper ores. The ore bodies are found in the form of multiple lodes regionally but locally in the forms of veins, stringers, dissemination, sporadic, cavity filling and replacement. Enriched mineralized zones are localized along the contact of Alwar and Ajabgarh group. Copper, the main entity in the belt occurs?dominantly as sulphides, oxides, carbonates and sulphosalts mineral hosted in pelitic and psammitic rocks. Pyrrhotite, pyrite, magnetite and sphalerite are the other ore mineral associated with the copper ore in a considerable amount. From the textural, structural and multigenerational minerals, mineral assemblage studies,?it is assumed that deposit has undergone metamorphism and multi-stage mineralization. Replacement has a profound influence on mineralization in the northern Khetri copper deposits.
