| 2 | The metabolome of induced pluripotent stem cells reveals metabolic changes occurring in somatic cell reprogramming显示文摘新陈代谢对房间功能的每个方面重要,然而,导致的 pluripotent 干细胞(iPSCs ) 的 metabolome 仍然保持大部分未经勘探。这里,我们报导,用一条 untargeted metabolomics 途径,那人的 iPSCs 份额有从他们的父母房间是不同的胚胎的干细胞(转换字符) 的 pluripotent metabolomic 签名,并且那被变化在涉及细胞的呼吸的代谢物描绘。细胞的 bioenergetics 的检查与我们的 metabolomic 分析支持了,并且证明体的房间在 pluripotency 从一个氧化状态变换成一个 glycolytic 状态。有趣地,各种各样的体的房间的 bioenergetics 与他们的 reprogramming 效率相关。我们进一步识别了在 iPSCs 和转换字符之间不同的代谢物,它揭示了在调整体的房间 reprogramming 起一个关键作用的新奇新陈代谢的小径。我们的调查结果是第一全球性分析 iPSCs 的 metabolome,并且提供机械学的卓见进涉及导致 pluripotency,并且在评估 iPSC 和转换字符等价的规定的新层。 | Athanasia D Panopoulos Oscar Yanes Sergio Ruiz Yasuyuki S Kida Dinh Diep Ralf Tautenhahn Aida Herrerias Erika M Batchelder Nongluk Plongthongkum Margaret Lutz W Travis Berggren Kun Zhang Ronald M Evans Gary Siuzdak Juan Carlos Izpisua Belmonte] | 2012 | Cell Research2012，22，1： | 12 |
| 3 | 牧草如何生长——植物生长与放牧管理之关联(英文)显示文摘适当管理饲料饲草资源的基本原则是理解多年生牧草如何生长。长期以来 ,对根系生长有了基本的了解 ,对去叶和环境对根系生长的影响也知之甚多。然而 ,对去叶、干旱及其他环境因素对多年生牧草的影响以及这些牧草对去叶的反应缺乏应有的理解。从牧草返青到开花 ,植物处于短枝阶段 ,适度放牧并不对多年生牧草的健康和活力造成危害 ,因为植物会弥补其失去的叶片。然而 ,当牧草从短枝向长枝阶段 (节间伸长和开花期 )转移时 ,碳水化合物主要用于节间伸长和开花过程。在开花后和休眠前期 ,碳水化合物主要向茎基和植物基部转移 ,以供来年新枝条的发育。因此 ,在花后和休眠前期 ,放牧系统必须被调节到“无放牧”状态。“无放牧”状态 ,如休息、轮牧、延迟轮牧和快速轮牧制 ,其价值在于这种定期的禁牧可提高多年生牧草的活力 ,改善草地的健康状况 ,并且在不利的环境条件下 。 | Ronald E Sosebee David B Wester J Carlos Villalobos Carlton M Britton Changgui Wan Hisham Nofal | 2005 | 草业学报2005，14，1： | 8 |

| 5 | Nationwide trends and predictors of inpatient mortality in 83884 transjugular intrahepatic portosystemic shunt显示文摘AIM: To evaluate and validate the national trends and predictors of in-patient mortality of transjugular intrahepatic portosystemic shunt(TIPS) in 15 years.METHODS: Using the National Inpatient Sample which is a part of Health Cost and Utilization Project, we identified a discharge-weighted national estimate of 83884 TIPS procedures performed in the United States from 1998 to 2012 using international classification of diseases-9 procedural code 39.1. The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality.RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospitalmortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients(OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients(OR = 1.347 vs non-transferred, P < 0.001), emergency admissions(OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region(OR = 1.449 vs West, P < 0.001) had significantly higher odds of inhospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death(OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure(OR = 8.246), acute kidney failure(OR = 4.359), hepatic encephalopathy(OR = 2.217) and esophageal variceal bleeding(OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites(OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders(OR = 2.823), coagulopathy(OR = 2.016), and lymphoma(OR = 1.842).CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay has remained relatively constant. Specific patient ethnicity, location, transfer status, primary diagnosis and comorbidities correlate with increased odds of TIPS in-hospital death. | Edward Wolfgang Lee Andrew Kuei Sammy Saab Ronald W Busuttil Francisco Durazo Steven-Huy Han Mohamed M El-Kabany Justin P Mc Williams Stephen T Kee | 2016 | World Journal of Gastroenterology2016，22，25： | 7 |
| 6 | Utilization of longitudinal ultrasound to quantify joint soft-tissue changes in a mouse model of posttraumatic osteoarthritis显示文摘To assess the utility of longitudinal ultrasound(US) to quantify volumetric changes in joint soft tissues during the progression of posttraumatic osteoarthritis(PTOA) in mice, and validate the US results with histological findings. A longitudinal cohort of 3-month-old wild-type C57 BL/6 male mice received the Hulth-Telhag surgical procedure on right knee to induce PTOA, and sham surgery on their left knee as control. US scans were performed on both knees before, 2, 4, 6, and 8 weeks post-surgery. Joint space volume and Power-Doppler(PD) volume were obtained from US images via Amira software. A parallel cross-sectional cohort of mice was killed at each US time point, and knee joints were subjected to histological analysis to obtain synovial soft-tissue area and OARSI scores. The correlation between US joint space volume and histological synovial soft-tissue area or OARSI score was assessed via linear regression analysis. US images indicated increased joint space volume in PTOA joints over time, which was associated with synovial inflammation and cartilage damage by histology. These changes started from 2 weeks post-surgery and gradually became more severe. No change was detected in sham joints. Increased joint space volume was significantly correlated with increased synovial soft-tissue area and the OARSI score(P o 0.001). PD signal was detected in the joint space of PTOA joints at 6 weeks post-surgery, which was consistent with the location of blood vessels that stained positively for CD31 and alpha-smooth muscle actin in the synovium.This study indicates that US is a cost-effective longitudinal outcome measure of volumetric and vascular changes in joint soft tissues during PTOA progression in mice, which positively correlates with synovial inflammation and cartilage damage. | Hao Xu Echoe M Bouta Ronald W Wood Edward M Schwarz Yongjun Wang Lianping Xing | 2017 | Bone Research2017，5，3： | 7 |
| 7 | Sonohysterography: Principles, technique and role in diagnosis of endometrial pathology显示文摘Sonohysterography (SHG), which provides enhanced endometrial visualization during standard transvaginal ultrasonography, is a relatively safe procedure for the evaluation of endometrial pathology. It can be used to evaluate patients with abnormal vaginal bleeding or infertility. This modality offers real time imaging of the endometrium without exposure to ionizing radiation. SHG is typically used in patients for whom standard transvaginal ultrasonography does not show the endometrium well, show a potential abnormality for which further imaging is required, or in patients without endometrial pathology defined on routine transvaginal imaging but in whom there is a strong clinical suspicion of an abnormality. This article will discuss the utility of the sonohysterogram in evaluation of various endometrial pathologies. Imaging examples of these pathological entities will be illustrated as well. | Thomas Yang Amit Pandya Leonardo Marcal Ronald O Bude Joel F Platt Deepak G Bedi Khaled M Elsayes | 2013 | World Journal of Radiology2013，5，3： | 5 |
| 8 | The Changing Cold Regions Network:Observation,diagnosis and prediction of environmental change in the Saskatchewan and Mackenzie River Basins,Canada显示文摘Climate change is causing rapid and severe changes to many Earth systems and processes,with widespread cryospheric,ecological,and hydrological impacts globally,and especially in high northern latitudes.This is of major societal concern and there is an urgent need for improved understanding and predictive tools for environmental management.The Changing Cold Regions Network(CCRN)is a Canadian research consortium with a focus to integrate existing and new experimental data with modelling and remote sensing products to understand,diagnose,and predict changing land,water,and climate,and their interactions and feedbacks over the geographic domain of the Mackenzie and Saskatchewan River Basins in Canada.The network operates a set of 14 unique and focused Water,Ecosystem,Cryosphere and Climate(WECC)observatories within this region,which provide opportunities to observe and understand processes and their interaction,as well as develop and test numerical simulation models,and provide validation data for remote sensing products.This paper describes this network and its observational,experimental,and modelling programme.An overview of many of the recent Earth system changes observed across the study region is provided,and some local insights from WECC observatories that may partly explain regional patterns and trends are described.Several of the model products being developed are discussed,and linkages with the local to international user community are reviewed—In particular,the use of WECC data towards model and remote sensing product calibration and validation is highlighted.Some future activities and prospects for the network are also presented at the end of the paper. | Chris M DEBEER Howard S WHEATER William L QUINTON Sean K CAREY Ronald E STEWART Murray D MACKAY Philip MARSH | 2015 | Science China Earth Sciences2015，58，1： | 5 |

| 10 | Tensile and fracture properties of an Mg-RE-Zn alloy at elevated temperatures显示文摘Magnesium alloy EZ10(Mg-RE-Zn) was deformed in tension at temperatures from 20 up to 520 °C. A rapid decrease of the yield and tensile strength with temperature was observed at temperatures higher than 300 °C. On the other hand, ductility of samples rapidly increased in the same temperature range. Light microscopy and scanning electron microscopy was used to reveal the reason for these behaviours. Intermetallic particles in grain boundaries are responsible for excellent mechanical properties at lower temperatures. Diffusional processes occurring at temperatures higher than 300 °C significantly influenced the deformation mechanism as well as the fracture character. | TROJANOVZuzanka DONI Tibor LUK Pavel PALEK Peter CHALUPOV Mária TILLOV Eva BASTOVANSKY Ronald | 2014 | Journal of Rare Earths2014，32，6： | 3 |

| 14 | A novel ZnO/reduced graphene oxide and Prussian blue modified carbon paste electrode for the sensitive determination of Rutin显示文摘A carbon paste modified sensor based on a novel composite of zinc oxide nanoparticles deposited on reduced graphene oxide(ZnO-rGrO) and Prussian blue(PB) was drop-cast(ZnO-rGrO-PB/MCPE) for the sensitive estimation of Rutin(Rtn) at pH 7.0.The high surface area of ZnO-rGrO and electrocatalytic property of PB promotes the oxidation of Rtn. Field emission scanning electron microscope(FE-SEM) and energy-dispersive X-ray spectroscopy(EDX) techniques were employed to confirm the deposition of ZnO-rGrO and PB on carbon paste electrode(CPE). The ability of ZnO-rGrO-PB/MCPE in charge transfer at the interface was investigated using electrochemical impedance spectroscopy(EIS). The heterogeneous rate constant(ks) and the charge transfer coefficient(α) have been calculated as 6.08 s^(-1) and 0.74 respectively. This sensor showed a wide linear response for Rtn from 7.0×10^(-8)to 7.0×10^(-6) M and 7.0×10^(-6) to 1.0×10^(-4) M with a limit of detection(2.05±0.04)×10^(-8) M(S/N=3). The application of ZnO-rGrO-PB/MCPE was found in the analysis of Rtn in fruit juice samples using standard addition method. This sensor showed good reproducibility, stability, selectivity and sensitivity. | Ozma J D'Souza Ronald J Mascarenhas Ashis K Satpati Basavanakote M Basavaraja | 2019 | Science China Chemistry2019，62，2： | 2 |
