10Colorectal cancer:Metastases to a single organ显示文摘Colorectal cancer(CRC) is a common malignancy worldwide. In CRC patients, metastases are the main cause of cancer-related mortality. In a group of metastatic CRC patients, the metastases are limited to a single site(solitary organ); the liver and lungs are the most commonly involved sites. When metastatic disease is limited to the liver and/or lungs, the resectability of the metastatic lesions will dictate the management approach and the outcome. Less commonly, the site of solitary organ CRC metastasis is the peritoneum. In these patients, cytoreduction followed by hyperthermic intraperitoneal chemotherapy may improve the outcome. Rarely, CRC involves other organs, such as the brain, bone, adrenals and spleen, as the only site of metastatic disease. There are limited data to guide clinical practice in these cases. Here, we have reviewed the disease characteristics, management approaches and prognosis based on the metastatic disease site in patients with CRC with metastases to a single organ.Sina Vatandoust Timothy J Price Christos S Karapetis 2015World Journal of Gastroenterology2015,21,41:30
11鄂西黄陵背斜南部元古宙庙湾蛇绿岩的发现及其构造意义显示文摘对鄂西黄陵背斜南部宜昌太平溪、邓村一带崆岭岩群中的元古宙庙湾岩组强烈变形变质超镁铁—镁铁质岩的研究表明,镁铁质岩主要为似层状细粒斜长角闪岩,变辉长岩岩体、岩脉及辉绿岩岩脉,超镁铁质岩则主要为蛇纹石化纯橄榄岩、方辉橄榄岩,呈构造岩片、岩块分布于斜长角闪岩之中。细粒斜长角闪岩TiO2=1.14%~1.48%,稀土元素配分型式为略亏损—平坦型,无明显的Eu异常,(La/Yb)N=0.87~1.12,La/Nb、Ce/Zr、Zr/Nb、Zr/Y、Ti/Y平均值分别为1.04、0.15、18.78、2.53、290.51,Nb/Th平均为9.88,显示为大洋中脊构造环境形成的N-MORB型拉斑玄武岩;变辉长岩具典型的堆晶结构特征,稀土元素配分型式为平坦型,具明显的Eu正异常;蛇纹石化纯橄榄岩的稀土元素配分型式具中稀土元素略亏损的U形特征,显示为LREE略富集的地幔岩。上述特征表明,黄陵背斜南部崆岭岩群中的元古宙庙湾岩组实际上是一套混杂堆积的古大洋蛇绿岩残片。元古宙庙湾蛇绿岩的发现为华南扬子克拉通存在中元古代洋盆和哥伦比亚超大陆聚合、裂解构造事件提供了重要的证据。彭松柏 李昌年 Kusky Timothy M 王璐 张先进 蒋幸福 熊承仁 2010地质通报2010,29,1:25
12权力关系、社区空间与乡村旅游利益获取——基于福建省泰宁县五个乡村社区的实证研究显示文摘权力关系主导着社区空间的生产及其利益分配。旅游规划作为一种权力工具,引发乡村社区空间的等级秩序发生变化,使乡村社区权力和利益分配出现新的非均衡发展的空间格局。旅游开发中政府权力主导的房屋拆迁、土地征用等介入方式可能导致乡村社区丧失旅游空间生产控制权。权力关系影响下的乡村社区与旅游生产的空间关联性、乡村社区的旅游参与性决定着社区居民的旅游利益。本文对福建省泰宁县的五个乡村旅游社区的调查研究证实了以上观点。景秀艳 Timothy J.Tyrrell 2012旅游科学2012,26,5:25
13Cardiac rehabilitation and exercise therapy in the elderly: Should we invest in the aged?显示文摘冠的心疾病(CHD ) 是世界范围的死亡的领先的原因并且在病人之中变得逐渐地流行 65 岁以上。老病人在为复杂并发症的更高的风险并且在一个心血管的事件以后加速物理 deconditioning,特别与他们的更年轻的对应物相比。最后几十年是到与 CHD 在病人之中在死亡,锻练能力,心理风险因素,发炎,和肥胖上表明了心脏的康复(CR ) 和锻练治疗的有益的效果的多重研究的厕所。不幸地,这个领域里的可得到的数据的重要部分与更年轻的病人相关。可行解释是更老的病人在为以病人开始并且延长到医生的多重原因的这些节目是非常未被充分代表的。在这篇文章,我们将考察 CR 节目的好处在之中老,以及一些妨碍他们的参予的障碍。Arthur R Menezes Carl J Lavie Richard V Milani Ross A Arena Timothy S Church 2012Journal of Geriatric Cardiology2012,9,1:25
14Targeting the PI3K-AKT-mTOR signaling network in cancer显示文摘The phosphoinositide 3-kinase-AKT-mammalian target of rapamycin (PI3K-AKT-mTOR) pathway is a frequently hyperactivated pathway in cancer and is important for tumor cell growth and survival. The development of targeted therapies against mTOR, a vital substrate along this pathway, led to the approval of allosteric inhibitors, including everolimus and temsirolimus, for the treatment of breast, renal, and pancreatic cancers. However, the suboptimal duration of response in unselected patients remains an unresolved issue. Numerous novel therapies against critical nodes of this pathway are therefore being actively investigated in the clinic in multiple tumour types. In this review, we focus on the progress of these agents in clinical development along with their biological rationale, the need of predictive biomarkers and various combination strategies, which will be useful in counteracting the mechanisms of resistance to this class of drugs.Khurum H. Khan Timothy A. Yap Li Yan David Cunningham 2013Chinese Journal of Cancer2013,32,5:25

16Observation of ocean current response to 1998 Hurricane Georges in the Gulf of Mexico显示文摘The ocean current response to a hurricane on the shelf-break is examined. The study area is the DeSoto Canyon in the northeast Gulf of Mexico, and the event is the passage of 1998 Hurricane Georges with a maximum wind speed of 49 m/s. The data sets used for analy- sis consist of the mooring data taken by the Field Program of the DeSoto Canyon Eddy Intrusion Study, and simultaneous winds ob- served by NOAA (National Oceanic and Atmospheric Administration) Moored Buoy 42040. Time-depth ocean current energy density images derived from the observed data show that the ocean currents respond almost immediately to the hurricane with important differ- ences on and off the shelf. On the shelf, in the shallow water of 100 m, the disturbance penetrates rapidly downward to the bottom and forms two energy peaks, the major peak is located in the mixed layer and the secondary one in the lower layer. The response dissipates quickly after external forcing disappears. Off the shelf, in the deep water, the major disturbance energy seems to be trapped in the mixed layer with a trailing oscillation; although the disturbance signals may still be observed at the depths of 500 and 1 290 m. Verti- cal dispersion analysis reveals that the near-initial wave packet generated off the shelf consists of two modes. One is a barotropic wave mode characterized by a fast decay rate of velocity amplitude of 0.020 s-1, and the other is baroclinic wave mode characterized by a slow decay rate of 0.006 9 s-1. The band-pass-filtering and empirical function techniques are employed to the frequency analysis. The results indicate that all frequencies shift above the local inertial frequency. On the shelf, the average frequency is 1.04f in the mixed layer, close to the diagnosed frequency of the first baroclinic mode, and the average frequency increases to 1.07f in the thermocline. Off the shelf, all frequencies are a little smaller than the diagnosed frequency of the first mode. The average frequency decreases from 1.035f in the mixed layer to 1.02f in the thermocline, implying a trend for the shift in frequency of the oscillations towards f with the depth.ZHENG Quanan LAI Ronald J HUANG Nortlen E PAN Jiayi LIU W Timothy 2006Acta Oceanologica Sinica2006,25,1:20
17Autoantibody to MOG suggests two distinct clinical subtypes of NMOSD显示文摘We characterized a unique group of patients with neuromyelitis optica spectrum disorder(NMOSD) who carried autoantibodies of aquaporin-4(AQP4) and myelin-oligodendrocyte glycoprotein(MOG). Among the 125 NMOSD patients, 10(8.0%) were AQP4- and MOG-ab double positive, and 14(11.2%) were MOG-ab single positive. The double-positive patients had a multiphase disease course with a high annual relapse rate(P=0.0431), and severe residual disability(P<0.0001). Of the double-positive patients, 70% had MS-like brain lesions, more severe edematous, multifocal regions on spinal magnetic resonance imaging(MRI), pronounced decreases of retinal nerve fiber layer thickness and atrophy of optic nerves. In contrast, patients with only MOG-ab had a higher ratio of monophasic disease course and mild residual disability. Spinal cord MRI illustrated multifocal cord lesions with mild edema, and brain MRIs showed more lesions around lateral ventricles. NMOSD patients carrying both autoantibodies to AQP4 and MOG existed and exhibited combined features of prototypic NMO and relapsing-remitting form of MS, whereas NMOSD with antibodies to MOG only exhibited an 'intermediate' phenotype between NMOSD and MS. Our study suggests that antibodies against MOG might be pathogenic in NMOSD patients and that determination of anti-MOG antibodies maybe instructive for management of NMOSD patients.Yaping Yan Yujing Li Ying Fu Li Yang Lei Su Kaibin Shi Minshu Li Qiang Liu Aimee Borazanci Yaou Liu Yong He Jeffrey L Bennett Timothy L Vollmer Fu-Dong Shi 2016Science China(Life Sciences)2016,59,12:20
18Geological Evidence for the Operation of Plate Tectonics throughout the Archean:Records from Archean Paleo-Plate Boundaries显示文摘Plate tectonics describes the horizontal motion of rigid lithospheric plates away from midoceanic ridges and parallel to transforms, towards deep-sea trenches, where the oceanic lithosphere is subducted into the mantle. This process is the surface expression of modern-day heat loss from Earth. One of the biggest questions in Geosciences today is 'when did plate tectonics begin on Earth' with a wide range of theories based on an equally diverse set of constraints from geology, geochemistry, numerical modeling, or pure speculation. In this contribution, we turn the coin over and ask 'when was the last appearance in the geological record for which there is proof that plate tectonics did not operate on the planet as it does today'. We apply the laws of uniformitarianism to the rock record to ask how far back in time is the geologic record consistent with presently-operating kinematics of plate motion, before which some other mechanisms of planetary heat loss may have been in operation. Some have suggested that evidence shows that there was no plate tectonics before 800 Ma ago, others sometime before 1.8–2.7 Ga, or before 2.7 Ga. Still others recognize evidence for plate tectonics as early as 3.0 Ga, 3.3–3.5 Ga, the age of the oldest rocks, or in the Hadean before 4.3 Ga. A key undiscussed question is: why is there such a diversity of opinion about the age at which plate tectonics can be shown to not have operated, and what criteria are the different research groups using to define plate tectonics, and to recognize evidence of plate tectonics in very old rocks? Here, we present and evaluate data from the rock record, constrained by relevant geochemical-isotopic data, and conclude that the evidence shows indubitably that plate tectonics has been operating at least since the formation of the oldest rocks, albeit with some differences in processes, compositions, and products in earlier times of higher heat generation and mantle temperature, weaker oceanic lithosphere, hotter subduction zones caused by more slab-melt generation, and under different biological and atmospheric conditions.Timothy M.Kusky Brian F.Windley Ali Polat 2018Journal of Earth Science2018,29,6:20
19氨基酸铁络合物对新生和哺乳仔猪铁营养状况的影响显示文摘用24头已与杜洛克父本配种的妊娠70天的(长×大)杂交母猪及其所生的24窝仔猪进行试验,研究不同铁源与注射铁剂补铁对新生和哺乳仔猪铁营养状况的影响。试验分为妊娠和泌乳两个阶段,均采用完全随机设计。在妊娠阶段,将妊娠70天的杂交母猪24头随机分为3个处理组,分别饲喂添加80mg/kg铁源于硫酸亚铁的玉米 豆粕 小麦麸型饲粮(正对照组)和在正对照组饲粮基础上添加120mg/kg铁源于氨基酸铁络合物的饲粮(有机铁组),以及在正对照组饲粮基础上添加120mg/kg铁源于硫酸亚铁的饲粮(无机铁组)。在泌乳阶段,泌乳母猪继续饲喂以上妊娠母猪的相应处理饲粮,而对来源于以上24头母猪的24窝新生仔猪,则设置成另外3个饲粮铁处理组,即来源于以上正对照组母猪的哺乳仔猪饲喂未添加铁的玉米 豆粕 干乳清粉 鱼粉型基础饲粮开食料(负对照组),来源于以上有机铁组母猪的哺乳仔猪饲喂在负对照组基础上添加120mg/kg铁源于氨基酸铁络合物的饲粮开食料(有机铁组),和来源于以上无机铁组母猪的哺乳仔猪饲喂在负对照组基础上添加120mg/kg铁源于硫酸亚铁的饲粮开食料(无机铁组)。每窝仔猪中有一半于出生后的第1天内以葡萄糖酸铁形式一次性注射100mg铁,另一半则不注射铁。哺乳仔猪于出生后的第5天开始喂给开食料,直到27日龄断奶结束。结果表?曾丽莉 陈婉如 罗绪刚 魏克强 Timothy M.Fakler 林燕 潘瑞珍 吕林 刘彬 2003畜牧兽医学报2003,34,1:20
20Irritable bowel syndrome: A microbiome-gut-brain axis disorder?显示文摘Irritable bowel syndrome(IBS) is an extremely prevalent but poorly understood gastrointestinal disorder. Consequently, there are no clear diagnostic markers to help diagnose the disorder and treatment options are limited to management of the symptoms. The concept of a dysregulated gut-brain axis has been adopted as a suitable model for the disorder. The gut microbiome may play an important role in the onset and exacerbation of symptoms in the disorder and has been extensively studied in this context. Although a causal role cannot yet be inferred from the clinical studies which have attempted to characterise the gut microbiota in IBS, they do confirm alterations in both community stability and diversity. Moreover, it has been reliably demonstrated that manipulation of the microbiota can influence the key symptoms, including abdominal pain and bowel habit, and other prominent features of IBS. A variety of strategies have been taken to study these interactions, including probiotics, antibiotics, faecal transplantations and the use of germ-free animals. There are clear mechanisms through which the microbiota can produce these effects, both humoral and neural. Taken together, these findings firmly establish the microbiota as a critical node in the gut-brain axis and one which is amenable to therapeutic interventions.Paul J Kennedy John F Cryan Timothy G Dinan Gerard Clarke 2014World Journal of Gastroenterology2014,20,39:20
