| 2 | Diagnosis of gastrointestinal bleeding: A practical guide for clinicians显示文摘Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians. | Bong Sik Matthew Kim Bob T Li Alexander Engel Jaswinder S Samra Stephen Clarke Ian D Norton Angela E Li | 2014 | World Journal of Gastrointestinal Pathophysiology2014,5,4: | 13 |

| 4 | In drug-induced, immune-mediated hepatitis, interleukin-33 reduces hepatitis and improves survival independently and as a consequence of FoxP3+ T-cell activity显示文摘Immune-mediated,drug-induced hepatitis is a rare complication of halogenated volatile anesthetic administration.IL-4-regulated Th2-polarized reactions initiate this type and other types of hepatitis,while the mechanisms that regulate the severity remain elusive.IL-33 is an innate,IL-4-inducing,Th2-polarizing cytokine that has been detected in patients with liver failure and has been associated with upregulated ST2+Foxp3+CD4+CD25+T cells;however,roles for IL-33 in drug-induced hepatitis are unclear.We investigated IL-33 in an anesthetic,immune-mediated hepatitis modeled in BALB/c,IL-33−/−and ST2−/−mice,as well as in patients with anesthetic hepatitis.The hepatic IL-33 and ST2 levels were elevated in BALB/c mice(p<0.05)with hepatitis,and anti-IL-33 diminished hepatitis(p<0.05)without reducing IL-33 levels.The complete absence of IL-33 reduced IL-10(p<0.05)and ST2+Foxp3+CD4+CD25+T cells(p<0.05),as well as reduced the overall survival(p<0.05),suggesting suppressive roles for IL-33 in anesthetic,immune-mediated hepatitis.All of the mice demonstrated similar levels of CD4+T-cell proliferation following direct Tcell receptor stimulation,but we detected splenic IL-33 and ST2-negative Foxp3+CD4+CD25+T cells in ST2−/−mice that developed less hepatitis than BALB/c mice(p<0.05),suggesting that ST2-negative Foxp3+CD4+CD25+T cells reduced hepatitis.In patients,serum IL-33 and IPEX levels were correlated in controls(r2=0.5,p<0.05),similar to the levels in mice,but not in anesthetic hepatitis patients(r2=0.01),who had elevated IL-33(p<0.001)and decreased IPEX(p<0.01).Our results suggest that,in anesthetic,immune-mediated hepatitis,IL-33 does not regulate the CD4+T-cell proliferation that initiates hepatitis,but IL-33,likely independent of ST2,reduces hepatitis via upregulation of Foxp3+CD4+CD25+T cells.Further studies are needed to translate the role of IL-33 to human liver disease. | Merylin Cottagiri Maeva Nyandjo Matthew Stephens Joel J.Mantilla Hirohisa Saito Ian R.Mackay Noel R.Rose Dolores B.Njoku | 2019 | Cellular & Molecular Immunology2019,16,8: | 4 |

| 6 | Comprehensive functional annotation of susceptibility variants identifies genetic heterogeneity between lung adenocarcinoma and squamous cell carcinoma显示文摘Although genome-wide association studies have identified more than eighty genetic variants associated with non-small cell lung cancer(NSCLC)risk,biological mechanisms of these variants remain largely unknown.By integrating a large-scale genotype data of 15581 lung adenocarcinoma(AD)cases,8350 squamous cell carcinoma(SqCC)cases,and 27355 controls,as well as multiple transcriptome and epigenomic databases,we conducted histology-specific meta-analyses and functional annotations of both reported and novel susceptibility variants.We identified 3064 credible risk variants for NSCLC,which were overrepresented in enhancer-like and promoter-like histone modification peaks as well as DNase I hypersensitive sites.Transcription factor enrichment analysis revealed that USF1 was AD-specific while CREB1 was SqCC-specific.Functional annotation and genebased analysis implicated 894 target genes,including 274 specifics for AD and 123 for SqCC,which were overrepresented in somatic driver genes(ER=1.95,P=0.005).Pathway enrichment analysis and Gene-Set Enrichment Analysis revealed that AD genes were primarily involved in immune-related pathways,while SqCC genes were homologous recombination deficiency related.Our results illustrate the molecular basis of both wellstudied and new susceptibility loci of NSCLC,providing not only novel insights into the genetic heterogeneity between AD and SqCC but also a set of plausible gene targets for post-GWAS functional experiments. | Na Qin Yuancheng Li Cheng Wang Meng Zhu Juncheng Dai Tongtong Hong Demetrius Albanes Stephen Lam Adonina Tardon Chu Chen Gary Goodman Stig EBojesen Maria Teresa Landi Mattias Johansson Angela Risch H-Erich Wichmann Heike Bickeboller Gadi Rennert Susanne Arnold Paul Brennan John KField Sanjay Shete Loic Le Marchand Olle Melander Hans Brunnstrom Geoffrey Liu Rayjean JHung Angeline Andrew Lambertus AKiemeney Shan Zienolddiny Kjell Grankvist Mikael Johansson Neil Caporaso Penella Woll Philip Lazarus Matthew BSchabath Melinda CAldrich Victoria LStevens Guangfu Jin David CChristiani Zhibin Hu Christopher IAmos Hongxia Ma Hongbing Shen | 2021 | Frontiers of Medicine2021,15,2: | 3 |
| 7 | Real-Time Hybrid Simulation of Seismically Isolated Structures with Full-Scale Bearings and Large Computational Models显示文摘Hybrid simulation can be a cost effective approach for dynamic testing of structural components at full scale while capturing the system level response through interactions with a numerical model.The dynamic response of a seismically isolated structure depends on the combined characteristics of the ground motion,bearings,and superstructure.Therefore,dynamic full-scale system level tests of isolated structures under realistic dynamic loading conditions are desirable towards a holistic validation of this earthquake protection strategy.Moreover,bearing properties and their ultimate behavior have been shown to be highly dependent on rate-of-loading and scale size effects,especially under extreme loading conditions.Few laboratory facilities can test full-scale seismic isolation bearings under prescribed displacement and/or loading protocols.The adaptation of a full-scale bearing test machine for the implementation of real-time hybrid simulation is presented here with a focus on the challenges encountered in attaining reliable simulation results for large scale dynamic tests.These advanced real-time hybrid simulations of large and complex hybrid models with several thousands of degrees of freedom are some of the first to use high performance parallel computing to rapidly execute the numerical analyses.Challenges in the experimental setup included measured forces contaminated by delay and other systematic control errors in applying desired displacements.Friction and inertial forces generated by the large-scale loading apparatus can affect the accuracy of measured force feedbacks.Reliable results from real-time hybrid simulation requires implementation of compensation algorithms and correction of these various sources of errors.Overall,this research program confirms that real-time hybrid simulation is a viable testing method to experimentally assess the behavior of full-scale isolators while capturing interactions with the numerical models of the superstructure to evaluate system level and in-structure response. | Alireza Sarebanha Andreas H.Schellenberg Matthew J.Schoettler Gilberto Mosqueda Stephen A.Mahin | 2019 | Computer Modeling in Engineering & Sciences2019,,9: | 3 |
| 8 | Gastric endoscopic submucosal dissection as a treatment for early neoplasia and for accurate staging of early cancers in a United Kingdom Caucasian population显示文摘AIM To investigate the efficacy of endoscopic submucosal dissection(ESD) at diagnosing and treating superficial neoplastic lesions of the stomach in a United Kingdom Caucasian population.METHODS Data of patients treated with or considered for ESD at a tertiary referral center in the United Kingdom were retrieved for a period of 2 years(May 2015 to June 2017) from the electronic patient records of the hospital. Only Caucasian patients were included. Primary outcomes were curative resection(CR) and were defined as ESD resections with clear horizontal and vertical margin and an absence of lympho-vascular invasion, poor differentiation and submucosal involvement on histological evaluation of the resected specimen. Secondary end-points were reversal of dysplasia at 12 mo endoscopic follow-up and/or at the latest follow up. Change in histological diagnosis pre and post ESD was also analysed.RESULTS Twenty-four patients were initially identified with intention to treat. 19 patients were eligible after mapping gastroscopy and ESD was attempted on a total of 25 ESD lesions, 4 of which failed and had to be aborted mid-procedure. Out of 21 ESD performed, en-bloc resection was achieved in 71.4% of cases. Resection was considered complete on endoscopy in 90.5% of cases compared to only 38.1% on histology. A total of 6 resections were considered curative(28%), 5 noncurative(24%) and 10 indefinite for CR or non-CR(24%). ESD changed the histological diagnosis in 66.6% of cases post ESD. Endoscopic follow-up in the 'indefinite' group and CR group showed that 50% and 80% of patients were clear of dysplasia at the latest follow-up respectively; 2 cases of recurrence were observed in the 'indefinite'group. Survival rate for the entire cohort was 91.7%.CONCLUSION This study provides early evidence for the efficacy of ESD as a therapeutic and diagnostic intervention in Caucasian populations and supports its application in the United Kingdom. | Aisha Sooltangos Matthew Davenport Stephen McGrath Jonathan Vickers Siba Senapati Kurshid Akhtar Regi George Yeng Ang | 2017 | World Journal of Gastrointestinal Endoscopy2017,9,12: | 3 |
| 9 | Trait associations in common bean genotypes grown under drought stress and field infestation by BSM bean fly显示文摘Understanding functional relations among plant traits and their modulation by growing conditions is imperative in designing selection strategies for breeding programs. This study assessed trait relationships among 196 common bean genotypes exposed to stresses for drought and field infestation of bean fly or bean stem maggot(BSM). The study was carried out at two locations and data was analyzed with linear correlation, path coefficient and genotype × trait biplot analyses. Multiple trait data related to mechanisms of drought and bean fly tolerance were collected on 196 genotypes grown under i) water deficit at mid-pod fill, or ii) unprotected against bean fly; iii) irrigated, well watered conditions, or iv) bean fly protection with chemicals. Seed yield exhibited positive and significant correlations with leaf chlorophyll content, vertical root pulling resistance, pod harvest index, pods per plant and seeds per pod at both phenotypic and genotypic levels under stress and non-stress conditions. Genotypic correlations of traits with seed yield were greater than their respective phenotypic correlations across environments indicating the greater contribution of genotypic factors to the trait correlation. Pods per plant and seeds per pod had high positive direct effects on seed yield both under stress and non-stress whereas pods per plant had the highest indirect effect on seed yield through pod harvest index under stress.In general, our results suggest that vertical root pulling resistance and pod harvest index are important selection objectives for improving seed yield in common beans under non-stress and stress conditions, and particularly useful for drought and BSM tolerance evaluation. | Daniel Ambachew Firew Mekbib Asrat Asfaw Stephen E.Beebe Matthew W.Blair | 2015 | The Crop Journal2015,3,4: | 3 |
| 10 | Identification of arylamine N-acetyltransferase inhibitors as an approach towards novel anti-tuberculars显示文摘New anti-tubercular drugs and drug targets are urgently needed to reduce the time for treatment and also to identify agents that will be effective against Mycobacterium tuberculosis persisting intracellularly.Mycobacteria have a unique cell wall.Deletion of the gene for arylamine N-acetyltransferase(NAT)decreases mycobacterial cell wall lipids,particularly the distinctive mycolates,and also increases antibiotic susceptibility and killing within macrophage of Mycobacterium bovis BCG.The nat gene and its associated gene cluster are almost identical in sequence in M.bovis BCG and M.tuberculosis.The gene cluster is essential for intracellular survival of mycobacteria.We have therefore used pure NAT protein for high-throughput screening to identify several classes of small molecules that inhibit NAT activity.Here,we characterize one class of such molecules—triazoles—in relation to its effects on the target enzyme and on both M.bovis BCG and M.tuberculosis.The most potent triazole mimics the effects of deletion of the nat gene on growth,lipid disruption and intracellular survival.We also present the structure-activity relationship between NAT inhibition and effects on mycobacterial growth,and use ligand-protein analysis to give further insight into the structure-activity relationships.We conclude that screening a chemical library with NAT protein yields compounds that have high potential as anti-tubercular agents and that the inhibitors will allow further exploration of the biochemical pathway in which NAT is involved. | Isaac M.Westwood Sanjib Bhakta Angela J.Russell Elizabeth Fullam Matthew C.Anderton Akane Kawamura Andrew W.Mulvaney Richard J.Vickers Veemal Bhowruth Gurdyal S.Besra Ajit Lalvani Stephen G.Davies Edith Sim | 2010 | Protein & Cell2010,1,1: | 3 |

| 14 | Do medical students studying in the United Kingdom have an adequate factual knowledge of basic life support?显示文摘BACKGROUND: Healthcare professionals have a duty to maintain basic life support(BLS) skills. This study aims to evaluate medical students' factual knowledge of BLS and the training they receive.METHODS: A cross-sectional, closed-response questionnaire was distributed to the fi rst-and fourth-year students studying at institutions in the United Kingdom. The paper questionnaire sought to quantify respondent's previous BLS training, factual knowledge of the BLS algorithm using five multiple choice questions(MCQs), and valuate their desire for further BLS training. Students received 1 point for each correctly identifi ed answer to the 5 MCQ's.RESULTS: A total of 3,732 complete responses were received from 21 medical schools. Eighty percent(n=2,999) of students completed a BLS course as part of their undergraduate medical studies. There was a signifi cant difference(P<0.001) in the percentage of the fourth-year students selecting the correct answer in all the MCQ's compared to the fi rst-year students except in identifyingthe correct depth of compressions required during CPR(P=0.095). Overall 10.3%(95% CI 9.9% to 10.7%) of respondents correctly identified the answer to 5 MCQ's on BLS: 9% of the first-year students(n=194) and 12% of the fourth-year students(n=190). On an institutional level the proportion of students answering all MCQ's correctly ranged from 2% to 54% at different universities. Eighty-one percent of students(n=3,031) wished for more BLS training in their curriculum.CONCLUSION: Factual knowledge of BLS is poor among medical students in the UK. There is a disparity in standards of knowledge across institutions and respondents indicating that they would like more training. | Robert D.Willmore Damjan Veljanoski Feray Ozdes Bethan Stephens James Mooney Seamus G.Crumley Arpan Doshi Philippa Davies Shreya Badhrinarayanan Emily Day Kristian Tattam April Wilson Nathan Crang Lorna Green Craig A.Mounsey Howell Fu Joseph Williams Michelle S.D'souza Dhanya Sebastian Liam A.Mcgiveron Matthew G.Percy James Cohen Imogen J.John Alice Lethbridge Imogen Watkins Omar Amin Mubasher A.Qamar John Gerrard Hanrahan Emily Cramond-Wong | 2019 | World Journal of Emergency Medicine2019,10,2: | 2 |
| 15 | Landscape features and weather influence nest survival of a ground-nesting bird of conservation concern,the greater sage-grouse,in humanaltered environments显示文摘Introduction:Ground-nesting birds experience high levels of nest predation.However,birds can make selection decisions related to nest site location and characteristics that may result in physical,visual,and olfactory impediments to predators.Methods:We studied daily survival rate[DSR]of greater sage-grouse(Centrocercus urophasianus)from 2008 to 2010 in an area in Wyoming experiencing large-scale alterations to the landscape.We used generalized linear mixed models to model fixed and random effects,and a correlation within nesting attempts,individual birds,and years.Results:Predation of the nest was the most common source of nest failure(84.7%)followed by direct predation of the female(13.6%).Generally,landscape variables at the nest site(≤30 m)were more influential on DSR of nests than features at larger spatial scales.Percentage of shrub canopy cover at the nest site(15-m scale)and distances to natural gas wells and mesic areas had a positive relationship with DSR of nests,whereas distance to roads had a negative relationship with DSR of nests.When added to the vegetation model,maximum wind speed on the day of nest failure and a 1-day lag in precipitation(i.e.,precipitation the day before failure)improved model fit whereby both variables negatively influenced DSR of nests.Conclusions:Nest site characteristics that reduce visibility(i.e.,shrub canopy cover)have the potential to reduce depredation,whereas anthropogenic(i.e.,distance to wells)and mesic landscape features appear to facilitate depredation.Last,predators may be more efficient at locating nests under certain weather conditions(i.e.,high winds and moisture). | Stephen L Webb Chad V Olson Matthew R Dzialak Seth M Harju Jeffrey B Winstead Dusty Lockman | 2012 | Ecological Processes2012,1,1: | 2 |
