4Modeling sustainability:population,inequality,consumption,and bidirectional coupling of the Earth and Human Systems显示文摘Over the last two centuries,the impact of the Human System has grown dramatically,becoming strongly dominant within the Earth System in many diferent ways.Consumption,inequality,and population have increased extremely fast,especially since about 1950,threatening to overwhelm the many critical functions and ecosystems of the Earth System.Changes in the Earth System,in turn,have important feedback efects on the Human System,with costly and potentially serious consequences.However,current models do not incorporate these critical feedbacks.We argue that in order to understand the dynamics of either system,Earth System Models must be coupled with Human System Models through bidirectional couplings representing the positive,negative,and delayed feedbacks that exist in the real systems.In particular,key Human System variables,such as demographics,inequality,economic growth,and migration,are not coupled with the Earth System but are instead driven by exogenous estimates,such as United Nations population projections.his makes current models likely to miss important feedbacks in the real Earth–Human system,especially those that may result in unexpected or counterintuitive outcomes,and thus requiring diferent policy interventions from current models.he importance and imminence of sustainability challenges,the dominant role of the Human System in the Earth System,and the essential roles the Earth System plays for the Human System,all call for collaboration of natural scientists,social scientists,and engineers in multidisciplinary research and modeling to develop coupled Earth–Human system models for devising efective science-based policies and measures to beneit current and future generations.Safa Motesharrei Jorge Rivas Eugenia Kalnay Ghassem R.Asrar Antonio J.Busalacchi Robert F.Cahalan Mark A.Cane Rita R.Colwell Kuishuang Feng Rachel S.Franklin Klaus Hubacek Fernando Miralles-Wilhelm Takemasa Miyoshi Matthias Ruth Roald Sagdeev Adel Shirmohammadi Jagadish Shukla Jelena Srebric Victor M.Yakovenko Ning Zeng 2016National Science Review2016,3,4:34
5Bactericidal and anti-adhesive properties of culinary and medicinal plants against Helicobacter pylori显示文摘AIM: To investigate the bactericidal and anti-adhesive properties of 25 plants against Helicobacter pylori (H pylori).METHODS: Twenty-five plants were boiled in water to produce aqueous extracts that simulate the effect of cooking. The bactericidal activity of the extracts was assessed by a standard kill-curve with seven strains of H pylori. The anti-adhesive property was assessed by the inhibition of binding of four strains of FITC-labeled H pylori to stomach sections. RESULTS: Of all the plants tested, eight plants, including Bengal quince, nightshade, garlic, dill, black pepper, coriander, fenugreek and black tea, were found to have no bactericidal effect on any of the isolates. Columbo weed, long pepper, parsley, tarragon, nutmeg, yellow-berried nightshade, threadstem carpetweed, sage and cinnamon had bactericidal activities against H pylori, but total inhibition of growth was not achieved in this study. Among the plants that killed H pylori, turmeric was the most efficient, followed by cumin, ginger, chilli, borage, black caraway, oregano and liquorice. Moreover, extracts of turmeric; borage and parsley were able to inhibit the adhesion of H pylori strains to the stomach sections.CONCLUSION: Several plants that were tested in our study had bactericidal and/or anti-adhesive effects on H pylori. Ingestion of the plants with anti-adhesive properties could therefore provide a potent alternative therapy for H pylori infection, which overcomes the problem of resistance associated with current antibiotic treatment.Rachel O'Mahony Huda Al-Khtheeri Deepaka Weerasekera Neluka Fernando Dino Vaira John Holton Christelle Basset 2005World Journal of Gastroenterology2005,11,47:29

8Coarctation of the aorta:Management from infancy to adulthood显示文摘Coarctation of the aorta is a relatively common form of congenital heart disease, with an estimated incidence of approximately 3 cases per 10000 births. Coarctation is a heterogeneous lesion which may present across all age ranges, with varying clinical symptoms, in isolation, or in association with other cardiac defects. The first surgical repair of aortic coarctation was described in 1944, and since that time, several other surgical techniques have been developed and modified. Additionally, transcatheter balloon angioplasty and endovascular stent placement offer less invasive approaches for the treatment of coarctation of the aorta for some patients. While overall morbidity and mortality rates are low for patients undergoing intervention for coarctation, both surgical and transcatheter interventions are not free from adverse outcomes. Therefore, patients must be followed closely over their lifetime for complications such as recoarctation, aortic aneurysm, persistent hypertension, and changes in any associated cardiac defects. Considerable effort has been expended investigating the utility and outcomes of various treatment approaches for aortic coarctation, which are heavily influenced by a patient's anatomy, size, age, and clinical course. Here we review indications for intervention, describe and compare surgical and transcatheter techniques for management of coarctation, and explore the associated outcomes in both children and adults.Rachel D Torok Michael J Campbell Gregory A Fleming Kevin D Hill 2015World Journal of Cardiology2015,7,11:27
9Recent advances in biodegradation controls over Mg alloys for bone fracture management: A review显示文摘Magnesium(Mg) alloys possess comparable physical and mechanical properties to bone, making them an outstanding candidate of implant materials for bone fracture treatment. In addition to the excellent biocompatibility, and bioactivity, the engagement of Mg alloys is key for a number of biological functionalities in the human body. The unique biodegradation nature of Mg alloy implants implies that it may not require a secondary removal procedure when the expected supporting tasks accomplish, as they may simply and safely 'disappear' over time. Nonetheless, the demonstrated drawback of potentially rapid degradation, is an issue that must be addressed appropriately for Mg implants and is consequently given unique attention in this review article. Herein, the critical criteria and the state-of-the-art strategies for controlling the degradation process of Mg alloys are reported. Furthermore, future developments of biodegradable Mg and its alloys systems with satisfactory specifications for clinical trials and deployment,are discussed. This review aims to provide information to materials scientists and clinical practitioners in the context of developing practical biodegradable Mg alloys.Ming-Shi Song Rong-Chang Zeng Yun-Fei Ding Rachel W.Li Mark Easton Ivan Cole Nick Birbilis Xiao-Bo Chen 2019Journal of Materials Science & Technology2019,35,4:26

15Mechanically induced Ca^(2+) oscillations in osteocytes release extracellular vesicles and enhance bone formation显示文摘The vast osteocytic network is believed to orchestrate bone metabolic activity in response to mechanical stimuli through production of sclerostin, RANKL, and osteoprotegerin(OPG). However, the mechanisms of osteocyte mechanotransduction remain poorly understood. We've previously shown that osteocyte mechanosensitivity is encoded through unique intracellular calcium (Ca^(2+) ) dynamics. Here, by simultaneously monitoring Ca^(2+) and actin dynamics in single cells exposed to fluid shear flow, we detected actin network contractions immediately upon onset of flow-induced Ca^(2+) transients, which were facilitated by smooth muscle myosin and further confirmed in native osteocytes ex vivo. Actomyosin contractions have been linked to the secretion of extracellular vesicles(EVs), and our studies demonstrate that mechanical stimulation upregulates EV production in osteocytes through immunostaining for the secretory vesicle marker Lysosomal-associated membrane protein 1(LAMP1) and quantifying EV release in conditioned medium, both of which are blunted when Ca^(2+) signaling was inhibited by neomycin. Axial tibia compression was used to induce anabolic bone formation responses in mice, revealing upregulated LAMP1 and expected downregulation of sclerostin in vivo. This load-related increase in LAMP1 expression was inhibited in neomycin-injected mice compared to vehicle.Micro-computed tomography revealed significant load-related increases in both trabecular bone volume fraction and cortical thickness after two weeks of loading, which were blunted by neomycin treatment. In summary, we found mechanical stimulation of osteocytes activates Ca^(2+) -dependent contractions and enhances the production and release of EVs containing bone regulatory proteins. Further, blocking Ca^(2+) signaling significantly attenuates adaptation to mechanical loading in vivo, suggesting a critical role for Ca^(2+) -mediated signaling in bone adaptation.Andrea E.Morrell Genevieve N.Brown Samuel T.Robinson Rachel L.Sattler Andrew D.Baik Gehua Zhen Xu Cao Lynda F.Bonewald Weiyang Jin Lance C.Kam X.Edward Guo 2018Bone Research2018,6,1:13

17词汇学习中“快速映射”现象的机制显示文摘词汇学习对于语言获得及有关认知能力发展有重要意义。通过考察儿童词汇的快速增长,研究者提出词汇学习涉及一个'快速映射'(fastmapping)过程。最近20多年,大量研究者考察了快速映射机制。一类研究者认为儿童依靠一些认知偏向来猜测新单词的意义;另一类研究者认为词汇频率、言语最末位置等语言环境因素影响该过程。最新研究趋向(如生成联合模型和词汇学习的贝叶斯推理模式)认为这两类因素都很重要,但对它们的作用时间和比重等仍有争议。陈永香 朱莉琪 Twila Tardif 孟祥芝 Rachel Pulverman 2009心理科学进展2009,17,1:13
18齐口裂腹鱼幼鱼疲劳后游泳特性恢复状况研究显示文摘以中国地质公园(神农架)野生动物繁育基地提供的齐口裂腹鱼(Schizothorax prenanti)幼鱼(体长为14.0—17.5 cm,体重为39.6—65.6 g)为研究对象,利用自制鱼类游泳特性(Swimming performance)研究装置,运用递增流速法(Stepped velocity test),研究了鱼类疲劳后20d和40d的游泳特性恢复状况。结果表明:(1)在20d内齐口裂腹鱼临界游泳速度(Critical swimming speed,Ucrit)相比于初次测试(20d前)有所降低,20d内的恢复状况较差;而在40d后,临界游泳速度已经基本恢复到最初状况,40d内的恢复状况较好。(2)疲劳后鱼类游泳效率显著下降,并且在40d后无法恢复正常。虽然40d后速度指数低于20d后速度指数,40d后游泳效率高于20d后游泳效率,但是相对于初次测试,40d后游泳效率恢复效果并不明显。(3)齐口裂腹鱼在疲劳后40d内,恢复能力(Recovery capability)无法恢复到正常状况,但由于3次测试中疲劳后过量耗氧(Excess post-exercise oxygen cost,EPOC)波动并不大,说明疲劳对其恢复能力影响并不大。(4)20d后和40d后无氧呼吸时间均较第一次测试时提前,说明疲劳损伤对其有氧呼吸能力产生了持续影响。(5)疲劳对鱼类生态行为(Ecological behavior)影响不明显。研究有利于为鱼道建设提供基础资料,对生物多样性保护具有深远意义。蔡露 刘国勇 Rachel Taupier 涂志英 石小涛 黄应平 2013水生生物学报2013,37,6:13
19【特刊综述】利用雄激素受体敲除(ARKO)小鼠模型认识人类雄激素缺乏显示文摘雄激素的作用机理很复杂。最近,使用转基因修饰小鼠模型进行的雄激素受体研究使我们对雄激素作用机理有了更进一步的理解。Cre-loxP系统能够完成组织和/或细胞特异性的敲除。通过使用Cre—loxP系统已经获得了大量整体性或组织特异性雄激素受体(ARK0)敲除模型。这些ARKO模型的多个雄激素作用位点,包括心血管系统、免疫和造血系统、骨骼、肌肉、脂肪组织、前列腺和脑,均已被检测。本篇综述着重阐述了通过针对这些雄激素作用位点的ARKO小鼠模型而取得的人类雄激素缺乏的研究成果,并且指出充分理解Cre-loxPdx鼠模型的优缺点才能正确认识其表型。Kesha Rana Rachel A Davey Jeffrey D Zajac 2014Asian Journal of Andrology2014,16,2:13
