Genomic diversity of colorectal cancer: Changing landscape and emerging targets

World Journal of Gastroenterology 2016年第25期22卷 5668-5677页

Improvements in screening and preventive measures.h.ve led to an increased detection of early stage colorectal cancers(CRC) where patients undergo treatment with a curative intent. Despite these efforts, a high proportion of patients are diagnosed with advanced stage disease that is associated with poor outcomes, as CRC remains one of the leading causes of cancer-related deaths in the world. The development of next generation sequencing and collaborative multiinstitutional efforts to characterize the cancer genome has afforded us with a comprehensive assessment of the genomic makeup present in CRC. This knowledge has translated into understanding the prognostic role of various tumor somatic variants in this disease. Additionally, the awareness of the genomic alterations present in CRC has resulted in an improvement in patient outcomes, largely due to better selection of personalized therapies based on an individual's tumor genomic makeup. The benefit of various treatments is often limited, where recent studies assessing the genomic diversity in CRC have identified the development of secondary tumor somatic variants that likely contribute to acquired treatment resistance. These studies.h.ve begun to alter the landscape of treatment for CRC that include investigating novel targeted therapies, assessing the role of immunotherapy and prospective, dynamic assessment of changes in tumor genomic alterations that occur during the treatment of CRC.

The use of a natural white juice, taken from magrabe banana stem, as concrete admixture to improve mechanical and physicrvchemical properties of concrete has been studied. The compressive strength, bulk density the free lime liberated during hydration and the combined water content were determined. The results indicate that the admixture acts as a retarder in most cases and as accelerator in some ones. Also, the admixture effect on the corrosion resistance of the reinforcing steel against surrounding aggressive media has been investigated using galvanostatic polarization technique. The addition of 0.2% admixture leads to the more inhibition of the steel

文学语义学:意义与暗示文学语义学理论,建立在语词或语句的意义与暗示的区分上。当格罗斯特(《李尔王》)对李尔说:“陛下,我们亲生的骨肉都变得那样坏,把自己生身之人当作了仇敌。”其字面意义是“他与李尔都被他们的孩子憎恨”,而暗示或暗指的却是“我们已完全堕落,我们憎恨我们赖以出生的性过程”。该句具有后者的暗示意义,因为它在特定环境下很容易引向这种解释。尽管直接上下文只有第一义,但《李尔王》剧中的性恐怖表达网却使这第二层意义言之成理.

当一位作者写出一部他声称是文学作品的本文时,他便给自己规定了一个确定的美学目的。相反,当一位读者将一部本文作为文学作品来解释时,他也赋予了作者一定的美学意图。将某一本文作为文学作品来进行解释,实际上就是将那些美学意图赋予作者的过程。作者创作文学作品,作为一种活动,旨在造成一种美学反应,这是他所必然期待于读者的。该美学意图的本质以及作为其旨归的反应是依照惯例确定的。一篇本文在读者眼里是否文学作品,他可以选择。

Generalized passivity-based chaos synchronization

引用

Applied Mathematics and Mechanics(English Edition) 2010年第8期31卷 1009-1018页

作者： C.K.ahn Faculty of the Division of Electronics and Control Engineering Wonkwang University

In this paper, a new passivity-based synchronization method for a general class of chaotic systems is proposed. Based on the Lyapunov theory and the linear matrix inequality （LMI） approach, the passivity-based controller is presented to make the synchronization error system not only passive but also asymptotically stable. The proposed controller can be obtained by solving a convex optimization problem represented by the LMI. simulation studies for the Genesio-Tesi chaotic system and the Qi chaotic system are presented to demonstrate the effectiveness of the proposed s.h.me.
