1LAMOST Experiment for Galactic Understanding and Exploration (LEGUE)——The survey's science plan显示文摘We describe the current plans for a spectroscopic survey of millions of stars in the Milky Way galaxy using the Guo Shou Jing Telescope (GSJT, formerly called the Large sky Area Multi-Object fiber Spectroscopic Telescope - LAMOST). The survey will obtain spectra for 2.5 million stars brighter than r < 19 during dark/grey time, and 5 million stars brighter than r < 17 or J < 16 on nights that are moonlit or have low transparency. The survey will begin in the fall of 2012, and will run for at least four years. The telescope's design constrains the optimal declination range for observations to 10 < δ < 50 , and site conditions lead to an emphasis on stars in the direction of the Galactic anticenter. The survey is divided into three parts with different target selection strategies: disk, anticenter, and spheroid. The resulting dataset will be used to study the merger history of the Milky Way, the substructure and evolution of the disks, the nature of the first generation of stars through identification of the lowest metallicity stars, and star formation through study of open clusters and OB associations. Detailed design of the LAMOST Experiment for Galactic Understanding and Exploration (LEGUE) survey will be completed in summer 2012, after a review of the results of the pilot survey.Li-Cai Deng Heidi Jo Newberg Chao Liu Jeffrey L.

2Drought Stress and Preharvest Aflatoxin Contamination in Agricultural Commodity: Genetics, Genomics and Proteomics显示文摘Throughout the world, aflatoxin contamination is considered one of the most serious food safety issues concerning health. Chronic problems with preharvest aflatoxin contamination occur in the southern US, and are particularly troublesome in corn, peanut, cottonseed, and tree nuts. Drought stress is a major factor to contribute to preharvest aflatoxin contamination. Recent studies have demonstrated higher concentration of defense or stress-related proteins in corn kernels of resistant genotypes compared with susceptible genotypes, suggesting that preharvest field condition (drought or not drought) influences gene expression differently in different genotypes resulting in different levels of 'end products': PR(pathogenesis-related) proteins in the mature kernels. Because of the complexity of Aspergillus-plant interactions, better understanding of the mechanisms of genetic resistance will be needed using genomics and proteomics for crop improvement. Genetic improvement of crop resistance to drought stress is one component and will provide a good perspective on the efficacy of control strategy. Proteomic comparisons of corn kernel proteins between resistant or susceptible genotypes to Aspergillus flavus infection have identified stress-related proteins along with antifungal proteins as associated with kernel resistance. Gene expression studies in developing corn kernels are in agreement with the proteomic studies that defense-related genes could be upregulated or downregulated by abiotic stresses.Baozhu Guo Zhi-Yuan Chen R.

4Neuroimaging the brain-gut axis in patients with irritable bowel syndrome显示文摘AIM:To summarize and synthesize current literature on neuroimaging the brain-gut axis in patients with irritable bowel syndrome(IBS).METHODS:A database search for relevant literature was conducted using Pub Med,Scopus and Embase in February 2015.Date filters were applied from the year2009 and onward,and studies were limited to those written in the English language and those performed upon human subjects.The initial search yielded 797articles,out of which 38 were pulled for full text review and 27 were included for study analysis.Investigations were reviewed to determine study design,methodology and results,and data points were placed in tabular format to facilitate analysis of study findings across disparate investigations.RESULTS:Analysis of study data resulted in the abstraction of four key themes:Neurohormonal differences,anatomic measurements of brain structure and connectivity,differences in functional responsiveness of the brain during rectal distention,and confounding/correlating patient factors.Studies in this review noted alterations of glutamate in the left hippocampus(HIPP),commonalities across IBS subjects in terms of brain oscillation patterns,cortical thickness/gray matter volume differences,and neuroanatomical regions withincreased activation in patients with IBS:Anterio cingulate cortex,mid cingulate cortex,amygdala anterior insula,posterior insula and prefrontal cortex.A striking finding among interventions was the substantia influence that patient variables(e.g.,sex,psychologica and disease related factors)had upon the identification of neuroanatomical differences in structure and con nectivity.CONCLUSION:The field of neuroimaging can provide insight into underlying physiological differences that distinguish patients with IBS from a healthy population.Kristen R Weaver Lee Anne B Sherwin Brian Walitt Gail D'Eramo Melkus Wendy A Henderson 2016World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,2:8
521世纪的卒中新定义:美国心脏协会/美国卒中协会对医疗专业人员的声明显示文摘尽管脑血管病的影响广泛且对其病理生理学的理解已取得一些进展,但“卒中”一词在临床实践、临床研究和公共卫生评价中的定义并不统一。经典的卒中定义主要是临床定义,不能反映科学技术的进步。因此,美国心脏协会卒中委员会/美国卒中协会召集了一个写作组,旨在对21世纪的卒中新定义制定一份专家共识文件。中枢神经系统(centralnervoussystem,CNS)梗死被定义为缺血导致的脑、脊髓或视网膜细胞死亡,并且具有永久性损伤的神经病理学、神经影像学和(或)临床证据。CNS梗死具有一系列临床表现:缺血性卒中特指伴有明显症状的CNS梗死,而无症状梗死则顾名思义不引起明显症状。广义的卒中还包括脑出血和蛛网膜下腔出血。卒中的新定义结合了临床和组织学标准,因此能被融入临床实践、研究和公共卫生评价。Ralph L.

8Monitoring the Expression of Maize Genes in Developing Kernels under Droug ht Stress usingOligo-microarray显示文摘Preharvest aflatoxin contamination of grain grown on the US southeastern Coast Plain is provoked and aggravated by abiotic stress. The primary abiotic stress is drought along with high temperatures. The objectives of the present study were to monitor gene expression in developing kernels in response to drought stress and to identify drought-responsive genes for possible use in germplasm assessment. The maize breeding line Tex6 was used, and gene expression profiles were analyzed in developing kernels under drought stress verses well-watered conditions at the stages of 25, 30, 35, 40, 45 d after pollination (DAP) using the 70 mer maize oligo-arrays. A total of 9 573 positive array spots were detected with unique gene IDs, and 7 988 were common in both stressed and well-watered samples. Expression patterns of some genes in several stress response-associated pathways, including abscisic acid, jasmonic acid and phenylalanine ammonia-lyase, were examined, and these specific genes were responsive to drought stress positively. Real-time quantitative polymerase chain reaction validated microarray expression data. The comparison between Tex6 and B73 revealed that there were significant differences in specific gene expression, patterns and levels. Several defense-related genes had been downregulated, even though some defense-related or drought responsive genes were upregulated at the later stages.Meng Luo Jia Liu R. Dewey Lee Brian T.

9Phase stability and mechanical properties of wire+arc additively manufactured H13 tool steel at elevated temperatures显示文摘Wire+arc additive manufacturing(WAAM)is considered an innovative technology that can change the manufacturing landscape in the near future.WAAM offers the benefits of inexpensive initial system setup and a high deposition rate for fabricating medium-and large-sized parts such as die-casting tools.In this study,AISI H13 tool steel,a popular die-casting tool metal,is manufactured by cold metal transfer(CMT)-based WAAM and is then comprehensively analyzed for its microstructural and mechanical properties.Location-dependent phase combinations are observed,which could be explained by nonequilibrium thermal cycles that resulted from the layer-by-layer stacking mechanism used in WAAM.In addition,remelting and reheating of the layers reduces welding anomalies(e.g.,pores and voids).The metallurgical characteristics of the H13 strongly correlate with the mechanical properties.The combinations of phases at different locations of the additively manufactured part exhibit a periodic microhardness profile.Martensite,Retained Austenite,Ferrite,and Carbide phases are found in combination at different locations of the part based on the part’s temperature distribution during additive deposition.Moreover,the tensile properties at elevated temperatures(23℃,300℃,and 600℃)are comparable to those from other WAAM and additive manufacturing(AM)processes.The X-ray diffraction results verify that the microstructural stability of the fabricated parts at high temperatures would allow them to be used in high temperatures.A.N.M.Tanvir Md.R.U.A hsan Gijeong Seo Brian Bates Chanho Lee Peter K.Liaw Mark Noakese Andrzej Nycz Changwook Ji Duck Bong Kim 2021Journal of Materials Science & Technology2021,,8:5

13FOCUS: Future of fecal calprotectin utility study in inflammatory bowel disease显示文摘AIM To evaluate the perspective of gastroenterologists regarding the impact of fecal calprotectin(FC) on the management of patients with inflammatory bowel disease(IBD).METHODS Patients with known IBD or symptoms suggestive of IBD for whom the physician identified that FC would be clinically useful were recruited. Physicians completed an online 'pre survey' outlining their rationale for the test. After receipt of the test results, the physicians completed an online 'post survey' to portray their perceived impact of the test result on patient management. Clinical outcomes for a subset of patients with follow-up data available beyond the completion of the 'post survey' were collected and analyzed.RESULTS Of 373 test kits distributed, 290 were returned, resulting in 279 fully completed surveys. One hundred and ninety patients were known to have IBD; 147(77%) with Crohn's Disease, 43(21%) Ulcerative Colitis and 5(2%) IBD unclassified. Indications for FC testing included: 90(32.2%) to differentiate a new diagnosis of IBD from Irritable Bowel Syndrome(IBS), 85(30.5%) to distinguish symptoms of IBS from IBD in those known to have IBD and 104(37.2%) as an objective measure of inflammation. FC levels resulted in a change in management 51.3%(143/279) of the time which included a significant reduction in the number of colonoscopies(118) performed(P < 0.001). Overall, 97.5%(272/279) of the time, the physicians found the test sufficiently useful that they would order it again in similar situations. Follow-up data was available for 172 patients with further support for the clinical utility of FC provided.CONCLUSION The FC test effected a change in management 51.3% of the time and receipt of the result was associated with a reduction in the number of colonoscopies performed.Greg Rosenfeld Astrid-Jane Greenup Andrew Round Oliver Takach Lawrence Halparin Abid Saadeddin Jin Kee Ho Terry Lee Robert Enns Brian Bressler 2016World Journal of Gastroenterology2016,22,36:2

15S100A4 released from highly bone-metastatic breast cancer cells plays a critical role in osteolysis显示文摘Bone destruction induced by breast cancer metastasis causes severe complications,including death,in breast cancer patients.Communication between cancer cells and skeletal cells in metastatic bone microenvironments is a principal element that drives tumor progression and osteolysis.Tumor-derived factors play fundamental roles in this form of communication.To identify soluble factors released from cancer cells in bone metastasis,we established a highly bone-metastatic subline of MDA-MB-231 breast cancer cells.This subline(mtMDA)showed a markedly elevated ability to secrete S100A4 protein,which directly stimulated osteoclast formation via surface receptor RAGE.Recombinant S100A4 stimulated osteoclastogenesis in vitro and bone loss in vivo.Conditioned medium from mtMDA cells in which S100A4 was knocked down had a reduced ability to stimulate osteoclasts.Furthermore,the S100A4 knockdown cells elicited less bone destruction in mice than the control knockdown cells.In addition,administration of an anti-S100A4 monoclonal antibody(mAb)that we developed attenuated the stimulation of osteoclastogenesis and bone loss by mtMDA in mice.Taken together,our results suggest that S100A4 released from breast cancer cells is an important player in the osteolysis caused by breast cancer bone metastasis.Haemin Kim Bongjun Kim Sang Il Kim Hyung Joon Kim Brian YRyu Junho Chung Zang Hee Lee Hong-Hee Kim 2019Bone Research2019,7,4:2

17Synthesis and electrocatalytic applications of flower-like motifs and associated composites of nitrogen-enriched tungsten nitride(W2N3)显示文摘We have sought to improve the electrocatalytic performance of tungsten nitride through synthetic control over chemical composition and morphology.In particular,we have generated a thermodynamically unstable but catalytically promising nitrogen-rich phase of tungsten via a hydrothermal generation of a tungsten oxide intermediate and subsequent annealing in ammonia.The net product consisted of three-dimensional(3D)micron-scale flower-like motifs of W2N3;this architecture not only evinced high structural stability but also incorporated the favorable properties of constituent two-dimensional nanosheets.From a performance perspective,as-prepared 3D W2N3 demonstrated promising hydrogen evolution reaction(HER)activities,especially in an acidic environment with a measured overpotential value of−101 mV at a current density of 10 mA/cm^2.To further enhance the electrocatalytic activity,small amounts of precious metal nanoparticles(such as Pt and Au),consisting of variable sizes,were uniformly deposited onto the underlying 3D W2N3 motifs using a facile direct deposition method;these composites were applied towards the CO2 reduction reaction(CO2RR).A highlight of this series of experiments was that Au/W2N3 composites were found to be a much more active HER(as opposed to either a CO2RR or a methanol oxidation reaction(MOR))catalyst.Sha Tan Brian M.Tackett Qun He Ji Hoon Lee Jingguang G.Chen Stanislaus S.Wong 2020Nano Research2020,13,5:2
