Multi-modality imaging review of congenital abnormalities of kidney and upper urinary tract

World Journal of Radiology 2016年第2期8卷 132-141页

作者： Subramaniyan Ramanathan Devendra Kumar Maneesh Khanna Mahmoud Al Heidous Adnan Sheikh vivek Virmani yegu Palaniappan Department of Clinical Imaging Al-Wakra Hospital Hamad Medical Corporation Department of Medical Imaging the Ottawa Hospital Department of Radiology Dr.Everett Chalmers Hospital Shree Meenakshi Multi Specialty Hospital

Congenital abnormalities of the kidney and urinary tract(CAKUT) include a wide range of abnormalities ranging from asymptomatic ectopic kidneys to life threatening renal agenesis(bilateral). Many of them are detected in the antenatal or immediate postnatal with a significant proportion identified in the adult population with varying degree of severity. CAKUT can be classified on embryological basis in to abnormalities in the renal parenchymal development, aberrant embryonic migration and abnormalities of the collecting system. Renal parenchymal abnormalities include multi cystic dysplastic kidneys, renal hypoplasia, number(agenesis or supernumerary), shape and cystic renal diseases. Aberrant embryonic migration encompasses abnormal location and fusion anomalies. Collecting system abnormalities include duplex kidneys and Pelvi ureteric junction obstruction. Ultrasonography(US) is typically the first imaging performed as it is easily available, noninvasive and radiation free used both antenatally and postnatally. Computed tomography(CT) and magnetic resonance imaging(MRI) are useful to confirm the ultrasound detected abnormality, detection of complex malformations, demonstration of collecting system and vascular anatomy and more importantly for early detection of complications like renal calculi, infection and malignancies. As CAKUT are one of the leading causes of end stage renal disease, it is important for the radiologists to be familiar with the varying imaging appearances of CAKUT on US, CT and MRI, thereby helping in prompt diagnosis and optimal management.

一直都很喜欢冬天,特别是冬天那素净的白雪。记得小时候因为想要留住冬天的雪,在下雪的时候便幼稚地把积雪装进玻璃瓶里储存起来,以为这样雪就不会消失了,奶奶看见后告诉我说＂雪还是会慢慢融化的＂,而我固执地不相信。存雪的第一天,雪并没有像奶奶说的那样融化掉,我庆幸地以为奶奶的话是骗我的,而在第二天,我却失望地发现储存在玻璃瓶中的白雪变成了清水,于是伤心了好一会儿。

近年来,印刷电子技术作为一种可实现低成本、大面积电子系统的技术,已获得了可观的收益。印刷允许进行充分有效的处理,从而降低了过程的复杂性,减少了材料的使用种类。加上使用如塑料、金属箔等低成本基板,预计印刷电子技术能实现更多领域电子系统的简单开发,包括显示器,传感器和RFID标签等。回顾印刷电子技术开发及应用工作,通过合成无机纳米粒子和有机材料的结合,可以制成一系列的印刷电子"油墨",并用于印刷无源元件、多层互联结构、二极管、晶体管、存储器、电池、不同类型的气体和生物传感器。通过拓展印刷能力,进一步降低将多种功能材料集成在相同基板上的成本。因此,开发出具有该优势的印刷系统是有可能的。

We report results of a search for light weakly interacting massive particle（WIMP） dark matter from the CDEX-1 experiment at the China Jinping Underground Laboratory（CJPL）. Constraints on WIMP-nucleon spin-independent（SI） and spin-dependent（SD） couplings are derived with a physics threshold of 160 eVee, from an exposure of 737.1 kg-days. The SI and SD limits extend the lower reach of light WIMPs to 2 GeV and improve over our earlier bounds at WIMP mass less than 6 GeV.

The CDEX-10 experiment searches for light weakly interacting massive particles, a form of dark matter, at the China Jinping Underground Laboratory, where approximately 10 kg of germanium detectors are arranged in an array and immersed in liquid nitrogen. Herein, we report on the experimental apparatus, detector characterization, and spectrum analysis of one prototype detector. Owing to the higher rise-time resolution of the CDEX-10 prototype detector as compared with CDEX-1 B, we identified the origin of an observed category of extremely fast events. For data analysis of the CDEX-10 prototype detector, we introduced and applied an improved bulk/surface event discrimination method. The results of the new method were compared to those of the CDEX-1 B spectrum. Both sets of results showed good consistency in the 0-12 ke Vee energy range, except for the 8.0 keV K-shell X-ray peak from the external copper.

近日，刊登在国际杂志Nature上的一项研究报告中，来自西南医学中心等机构的研究人员通过研究鉴别出了两个关键的核心基因，这两个基因能够帮助调节机体深度睡眠和做梦的水平，相关研究或为阐明相关的基因控制睡眠的网络提供新的线索。此前研究者通过对小鼠进行研究发现了能够控制机体快速眼动睡眠的基因，同时该基因还能够诱导深度睡眠。而第二个基因能够控制机体对快速眼动睡眠的需求量，相关研究为科学家们提供了一个关键的切入点来帮助解释睡眠工作的机制，同时研究者还鉴别出了治疗睡眠障碍的潜在靶点。

We report the first results on 76Ge neutrinoless double beta decay from stage one of the China dark-matter experiment （CDEX）. A p-type point-contact high-purity germanium detector with a mass of 994g has been installed to detect neutrinoless double beta decay events, as well as to directly detect dark matter particles. An exposure of 304kgd has been analyzed over a wide spectral band from 500keV to 3MeV. The average event rate obtained was about 0.012 counts per keV per kg per day over the 2.039MeV energy range. The half-life of76Ge neutrinoless double beta decay derived based on this result is 70v2〉6.4× 1022 yr （90%C.L.）. An upper limit on the effective Majorana-neutrino mass of 5.0eV has been achieved.

全球范围内城市聚落的增长影响着人类对自然资源的管理,从而促使自然科学和社会科学的学者们提倡以基于生态系统的途径来管理人类聚落。尽管过往有不少探讨基于生态系统管理(ecosystem-based management,以下简称EBM)的文献,但在制定环境政策时,却极少有城市和区域规划师将EBM因素考虑在内。本文对西华盛顿州的城市规划师在审视关于环境政策的科研数据时,在多大程度上运用EBM原则进行评估。笔者采用了现成文献中对EBM的定义,采访了42位在西华盛顿工作的环境规划师,询问其在审视有关科研数据时会考虑哪些EBM因素,并对访谈数据进行内容分析。结果显示,规划师们在审视与制定环境政策相关的科学文献时,会考虑监测、机构间合作、生态边界、价值取向乃至适应性管理等因素,但对于尺度、生态完整性和机构改革等因素,则会遇到阻碍或者说不会明确考虑。本文还阐述了为何有些EBM因素得到重视而另一些却被忽略,最后对通过应用EBM原则来改良城市环境政策的制定提出了建议。
