| 3 | 针对患者利益的机器学习和人工智能研究:在透明性、可重复性、伦理和有效性等方面的20个关键问题显示文摘机器学习(ML)、人工智能(AI)和其他现代统计方法正为利用先前尚未开发且极速增长的数据资源提供新的机会,以期让患者获益。尽管目前正在进行许多有前景的研究,特别是在图像方面,但就文献整体而言还缺乏透明度、对可重复性清晰的阐述、对潜在伦理问题的探究,以及对有效性的明确验证。这些问题的存在有许多原因,其中最重要的一点(为此我们提供了初步解决方案)就是当前缺乏针对ML和AI的最佳实践指南。我们认为从事研究的跨学科团队和应用ML/AI影响健康的项目,将因解决有关透明度、可重复性、伦理和有效性(TREE)的一系列问题而受益。这里提出的20个关键问题为研究团队提供了一个研究设计、实施和报告框架;帮助编辑和同行评审专家评估文献的贡献;让患者、临床医生和政策制定者评估新发现可能会给患者带来的获益。 | Sebastian Vollmer Bilal A Mateen Gergo Bohner Franz J Kirdly Rayid Ghani Pall Jonsson Sarah Cumbers Adrian Jonas Katherine S L McAllister Puja Myles David Granger Mark Birse Richard Branson Karel G M Moons Gary S Collins John P A Chris Holmes Harry Hemingwayp 李峰(译) 徐磊(校) 赵邑(校) | 2020 | 英国医学杂志中文版2020,23,9: | 5 |
| 4 | The effects of temperature and resource availability on denitrification and relative N_(2)O production in boreal lake sediments显示文摘Anthropogenic environmental stressors(like atmospheric deposition,land use change,and climate warming) are predicted to increase inorganic nitrogen and organic carbon loading to northern boreal lakes,with potential consequences for denitrification in lakes.However,our ability to predict effects of these changes is currently limited as northern boreal lakes have been largely neglected in denitrification studies.The aim of this study was therefore to assess how maximum potential denitrification and N_2O production rates,and the relationship between the two(relative N_2O production),is controlled by availability of nitrate(NO_3^-),carbon(C),phosphorus(P),and temperature.Experiments were performed using the acetylene inhibition technique on sediments from a small,nutrient poor boreal lake in northern Sweden in 2014.Maximum potential denitrification and N_2O production rates at 4°C were reached already at NO_3^-additions of 106–120 μg NO_3^-–N/L,and remained unchanged with higher NO_3 amendments.Higher incubation temperatures increased maximum potential denitrification and N_2O production rates,and Q10 was somewhat higher for N_2O production(1.77) than for denitrification(1.69).The relative N_2O production ranged between 13% and 64%,and was not related to NO_3^-concentration,but the ratio increased when incubations were amended with C and P(from a median of 16% to 27%).Combined,our results suggests that unproductive northern boreal lakes currently have low potential for denitrification but are susceptible to small changes in NO_3 loading especially if these are accompanied by enhanced C and P availability,likely promoting higher N_2O production relative to N_2. | Maria Myrstener Anders Jonsson Ann-Kristin Bergstrom | 2016 | Journal of Environmental Sciences2016,28,9: | 5 |
| 5 | Bone remodeling effect of a chitosan and calcium phosphate-based composite显示文摘Chitosan is a biocompatible polymer that has been widely studied for tissue engineering purposes.The aim of this research was to assess bone regenerative properties of an injectable chitosan and calcium phosphate-based composite and identify optimal degree of deacetylation(%DDA)of the chitosan polymer.Drill holes were generated on the left side of a mandible in Sprague-Dawley rats,and the hole was either left empty or filled with the implant.The animals were sacrificed at several time points after surgery(7–22 days)and bone was investigated using micro-CT and histology.No significant new bone formation was observed in the implants themselves at any time points.However,substantial new bone formation was observed in the rat mandible further away from the drill hole.Morphological changes indicating bone formation were found in specimens explanted on Day 7 in animals that received implant.Similar bone formation pattern was seen in control animals with an empty drill hole at later time points but not to the same extent.A second experiment was performed to examine if the%DDA of the chitosan polymer influenced the bone remodeling response.The results suggest that chitosan polymers with%DDA between 50 and 70%enhance the natural bone remodeling mechanism. | Lilja Kjalarsdottir Arna Dyrfjord Atli Dagbjartsson Elin H.Laxdal Gissur Orlygsson Johannes Gislason Jon M.Einarsson Chuen-How Ng Halldor Jonsson Jr | 2019 | Regenerative Biomaterials2019,6,4: | 3 |
| 6 | Macrophage secretory products induce an inflammatory phenotype in hepatocytes显示文摘AIM:To investigate the influence of macrophages on hepatocyte phenotype and function.METHODS:Macrophages were differentiated from THP-1 monocytes via phorbol myristate acetate stimulation and the effects of monocyte or macrophageconditioned medium on HepG2 mRNA and protein expression determined.The in vivo relevance of these findings was confirmed using liver biopsies from 147 patients with hepatitis C virus(HCV)infection.RESULTS:Conditioned media from macrophages,but not monocytes,induced a transient morphological change in hepatocytes associated with upregulation of vimentin(7.8±2.5-fold,P=0.045)and transforming growth factor(TGF)-β1(2.6±0.2-fold,P<0.001)and downregulation of epithelial cadherin(1.7±0.02-fold,P=0.017)mRNA expression.Microarray analysis revealed significant upregulation of lipocalin-2(17-fold,P <0.001)and pathways associated with inflammation,and substantial downregulation of pathways related to hepatocyte function.In patients with chronic HCV,realtime polymerase chain reaction and immunohistochemistry confirmed an increase in lipocalin-2 mRNA(F0 1.0 ±0.3,F1 2.2±0.2,F2 3.0±9.3,F3/4 4.0±0.8,P= 0.003)and protein expression(F1 1.0±0.5,F2 1.3± 0.4,F3/4 3.6±0.4,P=0.014)with increasing liver injury.High performance liquid chromatography-tandem mass spectrometry analysis identified elevated levels of matrix metalloproteinase(MMP)-9 in macrophageconditioned medium,and a chemical inhibitor of MMP-9 attenuated the change in morphology and mRNA expression of TGF-β1(2.9±0.2 vs 1.04±0.1,P<0.001) in macrophage-conditioned media treated HepG2 cells.In patients with chronic HCV infection,hepatic mRNA expression of CD163(F0 1.0±0.2,F1/2 2.8±0.3,F3/4 5.3±1.0,P=0.001)and MMP-9(F0 1.0±0.4,F1/2 2.8±0.3,F3/4 4.1±0.8,P=0.011)was significantly associated with increasing stage of fibrosis.CONCLUSION:Secreted macrophage products alter the phenotype and function of hepatocytes,with increased expression of inflammatory mediators,suggesting that hepatocytes actively participate in liver injury. | Michelle Melino Victoria L Gadd Gene V Walker Richard Skoien Helen D Barrie Dinesh Jothimani Leigh Horsfall Alun Jones Matthew J Sweet Gethin P Thomas Andrew D Clouston Julie R Jonsson Elizabeth E Powell | 2012 | World Journal of Gastroenterology2012,18,15: | 3 |
| 7 | 水生生态系统的富营养化和污染物显示文摘富营养化和长效污染物是欧洲海洋和淡水生态系统存在的主要环境问题。由于它们趋于共同产生,所以富营养化和污染物之间就有了相互作用,因而无法根据它们各自独立的作用过程来预测它们共同导致的环境影响。为了预测防治措施(改变有机质、营养物和污染物的输入)的效果,认识改变生物可利用性和污染物的迁移转化的机制是非常重要的。环境风险取决于污染物的种类形成和它们与媒介及其物质间的联系,并以此影响暴露程度。而且,风险也将取决于物质的流动性和它们在食物链中的路径。1995年,瑞典环境保护局发起了一项为期5年的研究项目'富营养化和污染物之间的相互作用(EUCON)'。前期准备的有关背景资料罗列了大量相关的问题和假设。在这些资料的基础上,项目开始启动,主要致力于海洋环境研究,重点集中在波罗的海及湖泊的富营养化和污染物(持续性有机化合物和微量金属)的相互作用上。本文总结了该项目研究的现状、前提和重点部分,强调了研究结果的应用及其意义。 | Jens Skei Per Larsson Rutger Rosenberg Per Jonsson Mats Olsson Dag Broman 鲁春霞 | 2000 | AMBIO-人类环境杂志2000,29,4: | 2 |

| 13 | Tissue-specific transcriptional imprinting and heterogeneity in human innate lymphoid cells revealed by full-length single-cell RNA-sequencing显示文摘The impact of the microenvironment on innate lymphoid cell(ILC)-mediated immunity in humans remains largely unknown.Here we used full-length Smart-seq2 single-cell RNA-sequencing to unravel tissue-specific transcriptional profiles and heterogeneity of CD127+ILCs across four human tissues.Correlation analysis identified gene modules characterizing the migratory properties of tonsil and blood ILCs,and signatures of tissue-residency,activation and modified metabolism in colon and lung ILCs.Trajectory analysis revealed potential differentiation pathways from circulating and tissue-resident naïve ILCs to a spectrum of mature ILC subsets.In the lung we identified both CRTH2+and CRTH2−ILC2 with lung-specific signatures,which could be recapitulated by alarmin-exposure of circulating ILC2.Finally,we describe unique TCR-V(D)J-rearrangement patterns of blood ILC1-like cells,revealing a subset of potentially immature ILCs with TCR-δ rearrangement.Our study provides a useful resource for in-depth understanding of ILC-mediated immunity in humans,with implications for disease. | Luca Mazzurana Paulo Czarnewski Viktor Jonsson Leif Wigge Markus Ringnér Teresa CWilliams Avinash Ravindran Åsa KBjörklund Jesper Säfholm Gunnar Nilsson Sven-Erik Dahlén Ann-Charlotte Orre Mamdoh Al-Ameri Charlotte Höög Charlotte Hedin Sylwester Szczegielniak Sven Almer Jenny Mjösberg | 2021 | Cell Research2021,31,5: | 2 |
| 14 | Irritable bowel syndrome: Physicians' awareness and patients' experience显示文摘AIM: To study if and how physicians use the irritable bowel syndrome (IBS) diagnostic criteria and to assess treatment strategies in IBS patients. METHODS: A questionnaire was sent to 191 physicians regarding IBS criteria, diagnostic methods and treatment. Furthermore, 94 patients who were diagnosed with IBS underwent telephone interview. RESULTS: A total of 80/191 (41.9%) physicians responded to the survey. Overall, 13 patients were diag-nosed monthly with IBS by specialists in gastroenterology (SGs) and 2.5 patients by general practitioners (GPs). All the SGs knew of the criteria to diagnose IBS, as did 46/70 (65.7%) GPs. Seventy-nine percent used the patient's history, 38% used a physical examination, and 38% exclusion of other diseases to diagnose IBS. Only 18/80 (22.5%) physicians used specific IBS criteria. Of the patients interviewed, 59/94 (62.8%) knew they had experienced IBS. Two out of five patients knew IBS and had seen a physician because of IBS symptoms. Half of those received a diagnosis of IBS. A total of 13% were satisfied with treatment. IBS affected daily activities in 43% of cases. CONCLUSION: Half of the patients with IBS who consulted a physician received a diagnosis. Awareness and knowledge of diagnostic criteria for IBS differ between SGs and GPs. | Linda Bjork Olafsdottir Hallgrímur Gudjonsson Heidur Hrund Jonsdottir Jon Steinar Jonsson Einar Bjornsson Bjarni Thjodleifsson | 2012 | World Journal of Gastroenterology2012,18,28: | 2 |
