4Diffusion-weighted magnetic resonance imaging to predict response of hepatocellular carcinoma to chemoembolization显示文摘AIM: To investigate whether intra-procedural diffusion- weighted magnetic resonance imaging can predict response of hepatocellular carcinoma (HCC) during trans- catheter arterial chemoembolization (TACE). METHODS: Sixteen patients (15 male), aged 59 ±11 years (range: 42-81 years) underwent a total of 21 separate treatments for unresectable HCC in a hybrid magnetic resonance/interventional radiology suite. Ana- tomical imaging and diffusion-weighted imaging (b = 0, 500 s/mm2) were performed on a 1.5-T unit. Tumor enhancement and apparent diffusion coefficient (ADC, mm2/s) values were assessed immediately before and at 1 and 3 mo after TACE. We calculated the percent change (PC) in ADC values at all time points. We compared follow-up ADC values to baseline values using a paired t test (α = 0.05). RESULTS: The intra-procedural sensitivity, specificity, and positive and negative predictive values (%) for detecting a complete or partial 1-mo tumor response using ADC PC thresholds of ±5%, ±10%, and ±15% were 77, 67, 91, and 40; 54, 67, 88, and 25; and 46, 100, 100, and 30, respectively. There was no clear predictive value for the 3-mo follow-up. Compared to baseline, the immediate post-procedure and 1-mo mean ADC values both increased; the latter obtaining statistical significance (1.48 ± 0.29 mm2/s vs 1.65 ± 0.35 × 10-3 mm2/s, P < 0.014). CONCLUSION: Intra-procedural ADC changes of > 15% predicted 1-mo anatomical HCC response with the greatest accuracy, and can provide valuable feedback at the time of TACE.Johnathan C Chung Neel K Naik Robert J Lewandowski Mary F Mulcahy Laura M Kulik Kent T Sato Robert K Ryu Riad Salem Andrew C Larson Reed A Omary 2010World Journal of Gastroenterology2010,16,25:13
5Effects of overburden characteristics on dynamic failure in underground coal mining显示文摘Dynamic failures, or ‘‘bumps', remain an imperative safety concern in underground coal mining, despite significant advancements in engineering controls. The presence of spatially discrete, stiff roof units are one feature that has been linked to these events. However, an empirical stratigraphic review indicates that no significant difference exists in the relative commonality of discrete units between bumping and non-bumping deposits. Instead an apparent relationship exists between reportable bumping and the overall stiffness of the host rock. However, this initial study is too simplistic to be conclusive; to weight the relative impact of changes in a single variable, such as the thickness or location of sandstone members, it must be examined in isolation—i.e., in a setting where all other variables are held constant.Numerical modelling provides this setting, and the effects of variability in a stiff discrete member in a hypothetical longwall mining scenario are investigated within the context of three stratigraphic ‘‘types',Compliant, Intermediate and Stiff. A modelling experiment examines changes in rupture potential in stiff roof units for each stratigraphic type as discrete unit thickness and location are manipulated through a range of values. Results suggest that the stiff-to-compliant ratio of the host rock has an impact on the relative stress-inducing effects of discrete stiff members. In other words, it is necessary to consider both the thickness and the distance to the seam, within the context of the host rock, to accurately anticipate areas of elevated rupture-induced hazard; acknowledging the presence of a discrete unit within the overburden in general terms is an insufficient indicator of risk. This finding helps to refine our understanding of the role of individual stiff, strong roof members in bumping phenomena, and suggests that a holistic view of overburden lithology and site-specific numerical modelling may be necessary to improve miner safety.Lawson Heather E.

6贵州草海越冬黑颈鹤飞出飞回夜栖地行为节律初步观察显示文摘野生动物行为节律常常是其对环境变化的一种行为适应。黑颈鹤(Grus nigricollis)越冬期会利用固定夜栖地,形成每天早晨飞出觅食,傍晚飞回夜栖的固定行为模式。为探索这一固定行为模式在越冬不同时期的变化及其影响因素,利用瞬时扫描法对草海湿地全部7个固定夜栖地的黑颈鹤飞出和飞回夜栖地准确时间及飞出之前和飞回之后在夜栖地的行为节律进行了观察。并且保证越冬前期(11月9日至12月31日)、中期(1月1日至2月21)和后期(2月22日至3月31日)3个阶段的调查时间分别不低于15 d。结果表明,越冬不同时期黑颈鹤飞出夜栖地时间差异极显著(F=23.38,P<0.01),飞回夜栖地时间存在显著性差异(F=3.51,P<0.05)。整个越冬期,黑颈鹤飞出夜栖地时间在中期延后,而到后期则更为提前,越冬前期、中期和后期飞出夜栖地的平均时间分别为7:34时、7:40时和7:13时;而飞回夜栖地时间逐渐延后,平均时间由前期的17:12时,至中期的17:40时和后期的18:15时。黑颈鹤飞出夜栖地之前的行为在越冬前期、中期和后期差异极显著(F=1 768.25,df=12,P<0.01),飞回夜栖地之后的行为在前期、中期和后期差异亦极显著(F=793.98,df=12,P<0.01)。越冬前期、中期和后期,黑颈鹤飞出夜栖地之前的行为与飞回夜栖地之后的行为均差异极显著(前期F=2 723.16,df=6,P<0.01;中期F=1 979.48,df=6,P<0.01;后期F=5 098.18,df=6,P<0.01)。黑颈鹤在飞出夜栖地前的80 min内,其行为以保养(34.32%)和休息(32.38%)为主;而飞回夜栖地后的90 min内,以觅食(43.04%)和休息(23.68%)为主。飞出时刻与日出时刻呈显著强相关(r=0.832,n=48,P<0.01),飞回时刻与日落时刻呈弱相关(r=0.353,n=47,P<0.01)。日出时间与黑颈鹤飞出夜栖地的时间的差值(Y1)受飞离时的空气湿度(W)影响,二者成反比,Y1=0.469﹣0.625W,P<0.05。黑颈鹤飞回夜栖地时刻与日落时刻的差值(Y2)受当天平均温度(T)的影响较为显著,Y2=1.231﹣0.107T,P<0.05,当天平均温度越高黑颈鹤飞回夜栖地时间越早,温度越低,黑颈鹤飞回夜栖地的时间越晚。研究结果对于进一步探讨黑颈鹤完整夜栖行为及其对干扰的适应性具有重要意义。孙喜娇 张明明 Hannah Larson 胡灿实 粟海军 2018动物学杂志2018,53,2:7
7863 genomes reveal the origin and domestication of chicken显示文摘Despite the substantial role that chickens have played in human societies across the world,both the geographic and temporal origins of their domestication remain controversial.To address this issue,we analyzed 863 genomes from a worldwide sampling of chickens and representatives of all four species of wild jungle fowl and each of the five subspecies of red jungle fowl(RJF).Our study suggests that domestic chickens were initially derived from the RJF subspecies Gallus gallus spadiceus whose present-day distribution is predominantly in southwestern China,northern Thailand and Myanmar.Following their domestication,chickens were translocated across Southeast and South Asia where they interbred locally with both RJF subspecies and other jungle fowl species.In addition,our results show that the White Leghorn chicken breed possesses a mosaic of divergent ancestries inherited from other subspecies of RJF.Despite the strong episodic gene flow from geographically divergent lineages of jungle fowls,our analyses show that domestic chickens undergo genetic adaptations that underlie their unique behavioral,morphological and reproductive traits.Our study provides novel insights into the evolutionary history of domestic chickens and a valuable resource to facilitate ongoing genetic and functional investigations of the world's most numerous domestic animal.Ming-Shan Wang Mukesh Thakur Min-Sheng Peng Yu Jiang Laurent Alain Francois Frantz Ming Li Jin-Jin Zhang Sheng Wang Joris Peters Newton Otieno Otecko Chatmongkon Suwannapoom Xing Guo Zhu-Qing Zheng Ali Esmailizadeh Nalini Yasoda Hirimuthugoda Hidayat Ashari Sri Suladari Moch Syamsul Arifin Zein Szilvia Kusza Saeed Sohrabi Hamed Kharrati-Koopaee Quan-Kuan Shen Lin Zeng Min-Min Yang Ya-Jiang Wu Xing-Yan Yang Xue-Mei Lu Xin-Zheng Jia Qing-Hua Nie Susan Joy Lamont Emiliano Lasagna Simone Ceccobelli Humpita Gamaralalage Thilini Nisanka Gunwardana Thilina Madusanka Senasige Shao-Hong Feng Jing-Fang Si Hao Zhang Jie-Qiong Jin Ming-Li Li Yan-Hu Liu Hong-Man Chen Cheng Ma Shan-Shan Dai Abul Kashem Fazlul Haque Bhuiyan Muhammad Sajjad Khan Gamamada Liyanage Lalanie Pradeepa Silva Thi-Thuy Le Okeyo Ally Mwai Mohamed Nawaz Mohamed Ibrahim Megan Supple Beth Shapiro Olivier Hanotte Guojie Zhang Greger Larson Jian-Lin Han Dong-Dong Wu Ya-Ping Zhang 2020Cell Research2020,30,8:7
8Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5

10对乙酰氨基酚引起的急性肝衰竭:一项美国多中心前瞻性研究结果显示文摘Severe acetaminophen hepatotoxicity frequently leads to acute liver failure (ALF). We determined the incidence, risk factors, and outcomes of acetaminophen- induced ALF at 22 tertiary care centers in the United States. Detailed prospective data were gathered on 662 consecutive patients over a 6- year period fulfilling standard criteria for ALF (coagulopathy and encephalopathy), from which 275 (42% )were determined to result from acetaminophen liver injury. The annual percentage of acetaminophen-related ALF rose during the study from 28% in 1998 to 51% in 2003. Median dose ingested was 24 g (equivalent to 48 extra-strength tablets). Unintentional overdoses accounted for 131 (48% ) cases, intentional (suicide attempts) 122 (44% ), and 22 (8% ) were of unknown intent. In the unintentional group, 38% took two or more acetaminophen preparations simultaneously, and 63% used narcotic-containing compounds. Eighty-one percent of unintentional patients reported taking acetaminophen and/or other analgesics for acute or chronic pain syndromes. Overall, 178 subjects (65% ) survived, 74 (27% ) died without transplantation, and 23 subjects (8% ) underwent liver transplantation; 71% were alive at 3 weeks. Transplant free survival rate and rate of liver transplantation were similar between intentional and unintentional groups. In conclusion, acetaminophen hepatotoxicity far exceeds other causes of acute liver failure in the United States. Susceptible patients have concomitant depression, chronic pain, alcohol or narcotic use, and/or take several preparations simultaneously. Education of patients, physicians, and pharmacies to limit high-risk use settings is recommended.Larson A.M. Polson J. Fontana R.J. 宋平 2006世界核心医学期刊文摘(胃肠病学分册)2006,2,8:5
11中年成人平均动脉压的体位改变与动脉硬度的关系:Framingham心脏研究显示文摘Torjesen A, Cooper LL, Rong J, Larson MG, Hamburg NM, Levy D, Benjamin EJ, Vasan RS, Mitchell GF.

12Behavior modeling and verification of movement authority scenario of Chinese Train Control System using AADL显示文摘Train control systems like most digital controllers are, by definition, hybrid systems as they interact with or try to control some aspects of the physical world. Detailed behavior modeling with constraints specification and formal verification, required for reliability prediction, is a great challenge for hybrid system designers.Train control systems further intensify this challenge with extensive interaction between computing units and their physical environment and their mutual dependence on each other. In this paper, we investigate behavior modeling and formal verification of Chinese Train Control System Level 3(CTCS-3) using Architectural Analysis & Design Language(AADL) to cope with this challenge. AADL is an architecture description language for embedded systems and is based on model-based engineering paradigm. Along with structural modeling of embedded systems using the core language constructs, AADL also provides support for language extension through annex sublanguages. In system requirements specification document, the behavior of the CTCS-3 is specified as a set of basic operation scenarios that cooperate with each other to achieve safe and secure functionality of trains.Movement Authority(MA) scenario, explored in this paper, is considered as a basic and most crucial scenario to prevent trains from colliding with each other. The detailed discrete behavior of control system is modeled and verified using the Behavior Language for Embedded Systems with Software(BLESS) annex sublanguage of AADL, and the continuous behavior of train with the cyber–physical interaction(communication between train and control system) is modeled using the Hybrid annex sublanguage. The behavior of the MA scenario at system level is verified using the Hybrid Hoare Logic theorem prover. Behavior constraints are specified as assertions using first-order logic formulas augmented with a simple temporal operator.AHMAD Ehsan DONG YunWei LARSON Brian Lü JiDong TANG Tao ZHAN NaiJun 2015Science China(Information Sciences)2015,58,11:4
13小儿哮喘的现代概念显示文摘尽管对哮喘的进展有些了解,但本病在小儿中的发病率及病死率仍高。虽然涉及很多因素,但主要的因素是过量应用β兴奋药加之抗炎药使用不足引起病死率增高。对轻度哮喘亦存在气道炎症的论证及炎性刺激增加气道反应性的观察致使在疾病较早期应用抗炎药。但目前可得到的具有抗炎活性的药物不是对全部病人均有效。由小儿慢性严重哮喘(尽管适当应用皮质类固醇)提出的问题,提示我们现在的概念过于简单化。因此,卫生保健人员在对该病治疗时必须保持清醒的头脑。Larson G L 张雪青 1993国外医学(儿科学分册)1993,20,1:4
14汉语中的轻语类和双系式移位显示文摘语言通过两种不同的形式可以表达一系列广泛的含义,也就是双系式和旁格式。双系式包含动词(v/V)的投射,常常有句法形态标记(-appl)。旁格式通常以介词短语的形式出现。双系式旁格形式:α动词-applβγα动词γ[介词β]含义:造成领属关系,受益/受害/替代关系,工具;造成移动/移位,刺激,方式,理由有的语言倾向于使用旁格形式(例如英语),有的语言倾向于使用双系式形式(例如伊博语),有的语言可以在两者之间比较自由地转换(例如卢旺达语)。这两种形式之间的句法关系——派生还是不同的中心语投射——存在争议。本文认为汉语的动词短语(vP/VP)属于双系式结构。具体来说,一系列汉语结构(包括双宾语、非典型宾语)都是双系式。我们在Larson(2014)的投射理论框架之下提出分析。此理论将题元角色分析成形式化的句法题元特征,题元角色的分配由题元特征之间核查一致关系来实现。我们也讨论了这个分析方法的语义解释,以及它和选择之间的联系。后者与其他轻动词的分析有重要区别。张冲 Larson,Richard 2017韵律语法研究2017,,1:3
15用分子标记研究禾本科赖草属植物可溶性碳水化合物、色素积累和生长特性之间的遗传相关性(英文)显示文摘在低温条件下 ,冷季草的可溶性碳水化合物通常与紫色素的积累、生长的缓慢性及对寒冷的适应性具有相关性。Vrn_1基因对一年生冬性禾本科物种的春化、生长和可溶性碳水化合物的积累有重要作用。本研究以Ley muscinereus×L .triticoides的杂种F1开放授粉获得的F2 群体为材料 ,用 2 0 4个未定位的AFLP分子标记和几个基因组特定的与vrn_1相连锁的DNA标记检测了控制可溶性碳水化合物的积累、紫色素的积累和生长特性等几个数量性状的QTL。根据生长特性和适应性可将Leymuscinereus和L .triticoides区分开来。研究表明可溶性碳水化合物与紫色素的积累呈正相关 ,而且有关基因对这两种性状具有多效性。与之相类似 ,分蘖、叶发育、叶生长、草被剪后的再生长和地下茎的蔓延性这些性状之间也呈正相关 ,控制这些性状的基因具有多效性。但是可溶性碳水化合物的积累与生长的缓慢性无相关性。有几个分子标记包括与vrn_Xm1邻近的一个分子标记对叶可溶性碳水化合物的浓度和低温生长具有正效应。而与vrn_Ns1邻近的一个DNA标记对分蘖具有更加特别的效应。我们推测vrn_1对多年生赖草低温下叶可溶性碳水化合物的积累及生长习性具有数量效应。发现几个DNA标记对可溶性碳水化合物的积累及多个生长特性有较强的作用。胡赞民 Steven R.

19Dog10K: an international sequencing effort to advance studies of canine domestication, phenotypes and health显示文摘Dogs are the most phenotypically diverse mammalian species, and they possess more known heritable disorders than any other non-human mammal. Efforts to catalog and characterize genetic variation across well-chosen populations of canines are necessary to advance our understanding of their evolutionary history and genetic architecture. To date, no organized effort has been undertaken to sequence the world’s canid populations. The Dog10 K Consortium(http://gffzz8e6b994fb05d4249hkk0cf0fxkvv96bop.ffgz.tsg.suse.edu.cn kgenomes.org) is an international collaboration of researchers from across the globe who will generate 20× whole genomes from 10 000 canids in 5 years.This effort will capture the genetic diversity that underlies the phenotypic and geographical variability of modern canids worldwide. Breeds, village dogs, niche populations and extended pedigrees are currently being sequenced, and de novo assemblies of multiple canids are being constructed. This unprecedented dataset will address the genetic underpinnings of domestication, breed formation, aging, behavior and morphological variation. More generally, this effort will advance our understanding of human and canine health.Elaine A.Ostrander Guo-Dong Wang Greger Larson Bridgett M.vonHoldt Brian W.Davis Vidhya Jagannathan Christophe Hitte Robert K.Wayne Ya-Ping Zhang the Dog10K Consortium 2019National Science Review2019,6,4:3
