| 1 | Recent advances and applications of machine learning in solidstate materials science显示文摘One of the most exciting tools that have entered the material science toolbox in recent years is machine learning.This collection of statistical methods has already proved to be capable of considerably speeding up both fundamental and applied research.At present,we are witnessing an explosion of works that develop and apply machine learning to solid-state systems.We provide a comprehensive overview and analysis of the most recent research in this topic.As a starting point,we introduce machine learning principles,algorithms,descriptors,and databases in materials science.We continue with the description of different machine learning approaches for the discovery of stable materials and the prediction of their crystal structure.Then we discuss research in numerous quantitative structure–property relationships and various approaches for the replacement of first-principle methods by machine learning.We review how active learning and surrogate-based optimization can be applied to improve the rational design process and related examples of applications.Two major questions are always the interpretability of and the physical understanding gained from machine learning models.We consider therefore the different facets of interpretability and their importance in materials science.Finally,we propose solutions and future research paths for various challenges in computational materials science. | Jonathan Schmidt Mário R.G.Marques Silvana Botti Miguel A.L.Marques | 2019 | npj Computational Materials2019，，1： | 49 |
| 2 | -765G > C COX-2 polymorphism may be a susceptibility marker for gastric adenocarcinoma in patients with atrophy or intestinal metaplasia显示文摘AIM: To investigate the relationship between the -765G > C COX-2 polymorphism and the development of different gastric lesions: atrophy or intestinal metaplasia and gastric adenocarcinoma. METHODS: A cross-sectional study was performed involving 320 Portuguese individuals (210 without evidence of neoplastic disease, 73 patients with gastric adenocarcinomas and 37 with atrophy or intestinal metaplasia) using a PCR-RFLP method. RESULTS: -765C allele was overrepresented in the patients with gastric adenocarcinoma (51%) when compared either with the control group (38%) or patients with atrophy or intestinal metaplasia (27%). Callele was found to be very common in our population (0.22), and a multivariate logistic regression analysis revealed nearly 3-fold increased risk for the progression to gastric adenocarcinoma in patients with atrophy or intestinal metaplasia carrying the -765C allele (OR = 2.67, 95% CI = 1.03-6.93; P = 0.04).considered as another susceptibility marker for gastric adenocarcinoma development in patients with atrophy or intestinal metaplasia. | Carina Pereira Hugo Sousa Paula Ferreira Maria Fragoso Luís Moreira-Dias Carlos Lopes Rui Medeiros Mário Dinis-Ribeiro | 2006 | World Journal of Gastroenterology2006，12，34： | 16 |
| 3 | Solutions for submucosal injection: What to choose and how to do it显示文摘During the past decades, endoscopic resection techniques have gradually improved and gained more importance for the management of premalignant lesions and early cancers. These endoscopic resection techniques can be divided in 3 major groups: snare polipectomy, endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD). The use of submucosal injection is essential for the majority of EMR techniques and is an integral part of ESD,whereas during polipectomy it is not crucial in most cases except to prevent bleeding in large polyps and/or those with large stalks as an alternative to mechanical methods. Injection provides a lifting up effect of the lesion separating it from the muscular layer, thereby reducing thermal injury and the risk of perforation and bleeding while also facilitating en-bloc resection by improving technical feasibility. With this work, we aim to review the most common endoscopic resection techniques and the importance of submucosal injection in each one of them. For that, we present some of the most commonly used submucosal injection solutions, taking into account their advantages and disadvantages. We also discuss, based on current recommendations and our own experience, how and when to preform submucosal injection, depending on lesions features and endoscopic resection technique that′s being used, to assure complete resection and to prevent associated adverse events. Finally, we also present and discuss some new proposed submucosal injection solutions,endoscopic resection techniques and devices that may have a major impact on the future of therapeutic endoscopy. | Rui Castro Diogo Libanio Inês Pita Mário Dinis-Ribeiro | 2019 | World Journal of Gastroenterology2019，25，7： | 13 |
| 4 | Role of mi RNAs and their potential to be useful as diagnostic and prognostic biomarkers in gastric cancer显示文摘Alterations in epigenetic control of gene expression play an important role in many diseases, including gastric cancer. Many studies have identified a large number of upregulated oncogenic mi RNAs and downregulated tumour-suppressor mi RNAs in this type of cancer. In this review, we provide an overview of the role of mi RNAs, pointing to their potential to be useful as diagnostic and/or prognostic biomarkers in gastric cancer. Moreover, we discuss the influence of polymorphisms and epigenetic modifications on mi RNA activity. | Kelly Cristina da Silva Oliveira Taíssa Maíra Thomaz Araújo Camila Inagaki Albuquerque Gabriela Alcantara Barata Carolina Oliveira Gigek Mariana Ferreira Leal Fernanda Wisnieski Fernando Augusto Rodrigues Mello Junior André Salim Khayat Paulo Pimentel de Assumpcao Rommel Mário Rodriguez Burbano Marília Cardoso Smith Danielle Queiroz Calcagno | 2016 | World Journal of Gastroenterology2016，22，35： | 11 |
| 5 | Biliary tract schwannoma:A rare cause of obstructive jaundice in a young patient显示文摘Schwannoma is a tumor derived from Schwann cells which usually arises in the upper extremities, trunk, head and neck, retroperitoneum, mediastinum, pelvis, and peritoneum. However, it can arise in the gastro-intestinal tract, including biliary tract. We present a 24-year-old male patient with obstructive jaundice, whose investigation with computed tomography abdomen showed focal wall thickening in the common hepatic duct, difficult to differentiate with hilar adenocarcinoma. He was diagnosed intraoperatively schwannoma of common bile duct and treated with local resection. The patient recovered well without signs of recurrence of the lesion after 12 mo. We also reviewed the common bile duct schwannoma related in the literature and evaluated the difficulty in pre and intraoperative differential diagnosis with adenocarcinoma hilar. Resection is the treatment of choice for such cases and the tumordid not recur in any of the resected cases. | Gilton Marques Fonseca André Luis Montagnini Manoel de Souza Rocha Rosely Antunes Patzina Mário Vinícius Angelete Alvarez Bernardes Ivan Cecconello José Jukemura | 2012 | World Journal of Gastroenterology2012，18，37： | 10 |
| 6 | Hepatic abscess induced by foreign body:Case report and literature review显示文摘Hepatic abscess due to perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon. Pre-operative diagnosis is difficult as patients are often unaware of the foreign body ingestion and symptoms and imagiology are usually non-specific. The authors report a case of 62-year-old woman who was admitted with fever and abdominal pain. Further investigation revealed hepatic abscess, without resolution despite antibiotic therapy. A liver abscess resulting from perforation and intra-hepatic migration of a bone coming from the pilorum was diagnosed by surgery. The literature concerning foreign body-induced perforation of the gastrointestinal tract complicated by liver abscess is reviewed. | Sofia A Santos Sara CF Alberto Elsa Cruz Eduardo Pires Tomás Figueira lia Coimbra José Estevez Mário Oliveira Luís Novais Joo R Deus | 2007 | World Journal of Gastroenterology2007，13，9： | 10 |
| 7 | Thalidomide induces mucosal healing in Crohn's disease: Case report显示文摘Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract that is defi ned by relapsing and remitting episodes. Tumor necrosis factor alpha (TNF-α) appears to play a central role in the pathophysiology of the disease. Standard therapies for inflammatory bowel disease fail to induce remission in about 30% of patients. Biological therapies have been associated with an increased incidence of infections, especially infection by Mycobacterium tuberculosis (Mtb). Thalidomide is an oral immunomodulatory agent with anti-TNF-α properties. Recent studies have suggested that thalidomide is effective in refractory luminal and fistulizing Crohn's disease. Thalidomide costimulates T lymphocytes, with greater effect on CD8+ than on CD4+ T cells, which contributes to the protective immune response to Mtb infection. We present a case of Crohn's disease with gastric, ileal, colon and rectum involvement as well as steroid dependency, which progressed with loss of response to infliximabafter three years of therapy. The thorax computed tomography scan demonstrated a pulmonary nodule suspected to be Mtb infection. The patient was started on thalidomide therapy and exhibited an excellent response. | Márcio Rios Leite Sandra Sousa Santos André Castro Lyra Jaciane Mota Genoile Oliveira Santana | 2011 | World Journal of Gastroenterology2011，17，45： | 9 |

| 9 | Helicobacter pylori and microRNAs:Relation with innate immunity and progression of preneoplastic conditions显示文摘The accepted paradigm for intestinal-type gastric cancer pathogenesis is a multistep progression from chronic gastritis induced by Helicobacter pylori(H. pylori) to gastric atrophy, intestinal metaplasia, dysplasia and ultimately gastric cancer. The genetic and molecular mechanisms underlying disease progression are still not completely understood as only a fraction of colonized individuals ever develop neoplasia suggesting that bacterial, host and environmental factors are involved. Micro RNAs are noncoding RNAs that may influence H. pylori-related pathology through the regulation of the transcription and expression of various genes, playing an important role in inflammation, cell proliferation, apoptosis and differentiation. Indeed, H. pylori have been shown to modify micro RNA expression in the gastric mucosa and micro RNAs are involved in the immune host response to the bacteria and in the regulation of the inflammatory response. Micro RNAs have a key role in the regulation of inflammatory pathways and H. pylori may influence inflammation-mediated gastric carcinogenesis possibly through DNA methylation and epigenetic silencing of tumor suppressor micro RNAs. Furthermore, micro RNAs influenced by H. pylori also have been found to be involved in cell cycle regulation, apoptosis and epithelial-mesenchymal transition. Altogether, micro RNAs seem to have an important role in the progression from gastritis to preneoplastic conditions and neoplastic lesions and since each micro RNA can control the expression of hundreds to thousands of genes, knowledge of micro RNAs target genes and their functions are of paramount importance. In this article we present a comprehensive review about the role of micro RNAs in H. pylori gastric carcinogenesis, identifying the micro RNAs downregulated and upregulated in the infection and clarifying their biological role in the link between immune host response, inflammation, DNA methylation and gastric carcinogenesis. | Diogo Libanio Mário Dinis-Ribeiro Pedro Pimentel-Nunes | 2015 | World Journal of Clinical Oncology2015，6，5： | 7 |
| 10 | Tooth-derived stem cells: Update and perspectives显示文摘Tissue engineering is an emerging field of science that focuses on creating suitable conditions for the regeneration of tissues. The basic components for tissue engineering involve an interactive triad of scaffolds, signaling molecules, and cells. In this context,stem cells(SCs) present the characteristics of selfrenewal and differentiation capacity, which make them promising candidates for tissue engineering. Although they present some common markers, such as cluster of differentiation(CD)105, CD146 and STRO-1, SCs derived from various tissues have different patterns in relation to proliferation, clonogenicity, and differentiation abilities in vitro and in vivo. Tooth-derived tissues have been proposed as an accessible source to obtain SCs with limited morbidity, and various tooth-derived SCs(TDSCs) have been isolated and characterized, such as dental pulp SCs, SCs from human exfoliated deciduous teeth, periodontal ligament SCs, dental follicle progenitor cells, SCs from apical papilla, and periodontal ligament of deciduous teeth SCs. However, heterogeneity among these populations has been observed, and the best method to select the most appropriate TDSCs for regeneration approaches has not yet been established. The objective of this review is to outline the current knowledge concerning the various types of TDSCs, and discuss the perspectives for their use in regenerative approaches. | Miki Taketomi Saito Karina Gonzales Silvério Márcio Zaffalon Casati Enilson Antonio Sallum Francisco Humberto Nociti Jr | 2015 | World Journal of Stem Cells2015，7，2： | 6 |

| 12 | Renal sympathetic denervation in resistant hypertension显示文摘Resistant hypertension remains a major clinical problem despite the available multidrug therapy.Over the next decades,its incidence will likely increase given that it is strongly associated with older age and obesity.Resistant hypertension patients have an increased cardiovascular risk,thus effective antihypertensive treatment will provide substantial health benefits.The crosstalk between sympathetic nervous system and kidneys plays a crucial role in hypertension.It influences several pathophysiological mechanisms such as the central sympathetic tone,the sodium balance and the systemic neurohumoral activation.In fact,studies using several animal models demonstrated that the renal denervation prevented and attenuated hypertension in multiple species.Large reductions in blood pressure were also observed in malignant hypertension patients submitted to sympathectomy surgeries.However,these approaches had an unacceptably high rates of periprocedural complications and disabling adverse events.Recently,an innovative non-pharmacological therapy that modulates sympathetic activation has been successfully developed.Renal sympathetic percutaneous denervation is an endovascular procedure that uses radiofrequency energy to destroy the autonomic renal nerves running inside the adventitia of renal arteries.This method represents a promising new approach to the strategy of inhibiting the sympathetic nervous system.The aim of this review is to examine the background knowledge that resulted in the development of this hypertension treatment and to critically appraise the available clinical evidence. | Mário Santos Henrique Carvalho | 2013 | World Journal of Cardiology2013，5，4： | 5 |

| 15 | Assessing the relationship between the rumen microbiota and feed efficiency in Nellore steers显示文摘Background:Ruminants rely upon a complex community of microbes in their rumen to convert host-indigestible feed into nutrients.However,little is known about the association between the rumen microbiota and feed efficiency traits in Nellore(Bos indicus)cattle,a breed of major economic importance to the global beef market.Here,we compare the composition of the bacterial,archaeal and fungal communities in the rumen of Nellore steers with high and low feed efficiency(FE)phenotypes,as measured by residual feed intake(RFI).Results:The Firmicutes to Bacteroidetes ratio was significantly higher(P<0.05)in positive-RFI steers(p-RFI,low feed efficiency)than in negative-RFI(n-RFI,high feed efficiency)steers.The differences in bacterial composition from steers with high and low FE were mainly associated with members of the families Lachnospiraceae,Ruminococcaceae and Christensenellaceae,as well as the genus Prevotella.Archaeal community richness was lower(P<0.05)in p-RFI than in n-RFI steers and the genus Methanobrevibacter was either increased or exclusive of p-RFI steers.The fungal genus Buwchfawromyces was more abundant in the rumen solid fraction of n-RFI steers(P<0.05)and a highly abundant OTU belonging to the genus Piromyces was also increased in the rumen microbiota of highefficiency steers.However,analysis of rumen fermentation variables and functional predictions indicated similar metabolic outputs for the microbiota of distinct FE groups.Conclusions:Our results demonstrate that differences in the ruminal microbiota of high and low FE Nellore steers comprise specific taxa from the bacterial,archaeal and fungal communities.Biomarker OTUs belonging to the genus Piromyces were identified in animals showing high feed efficiency,whereas among archaea,Methanobrevibacter was associated with steers classified as p-RFI.The identification of specific RFI-associated microorganisms in Nellore steers could guide further studies targeting the isolation and functional characterization of rumen microbes potentially important for the energy-harvesting efficiency of ruminants. | Déborah Romaskevis Gomes Lopes Márcio de Souza Duarte Alex J.La Reau Ibrahim Zuniga Chaves Tiago Antônio de Oliveira Mendes Edenio Detmann Cláudia Braga Pereira Bento Maria Eugênia Zerlotti Mercadante Sarah Figueiredo Martins Bonilha Garret Suen Hilário Cuquetto Mantovani | 2021 | Journal of Animal Science and Biotechnology2021，12，4： | 3 |
| 16 | Association between EGF +61A/G polymorphism and gastric cancer in Caucasians显示文摘AIM: To investigate the association between epidermal growth factor (EGF) +61A/G polymorphism and susceptibility to gastric cancer, through a cross-sectional study. METHODS: Polymerase chain reaction resctriction fragment lenght polymorphism analyses were used to genotype EGF +61 in 207 patients with gastric lesions (162 patients with gastric adenocarcinomas, 45 with atrophy or intestinal metaplasia) and 984 controls. All subjects were Caucasian. RESULTS: Genotype distribution was 23.5% for GG and 76.5% for GA/AA in the control group, 18.4% for GG and 68.6% for GA/AA in the entire group with gastric lesions and 17.9% for GG and 82.1% for GA/AA in the group with gastric adenocarcinoma. No statistically significant associations were found between EGF +61 variants and risk for developing gastric cancer [odds ratios (OR) = 1.41, 95% confidence intervals (CI): 0.90-2.21, P = 0.116]. However, the stratification of individuals by gender revealed that males carrying A alleles (EGF +61A/G or AA) had an increased risk for developing gastric cancer as compared to GG homozygous males (OR = 1.55, 95% CI: 1.05-2.28, P = 0.021). CONCLUSION: In summary, we found that males who were A carriers for EGF +61 had an increased risk for developing gastric cancer. This result may be explained by the suggestion that women secrete less gastric acid than men. | Ana Paula Araújo Bruno M Costa Ana L Pinto-Correia Maria Fragoso Paula Ferreira Mário Dinis-Ribeiro Sandra Costa Rui M Reis Rui Medeiros | 2011 | World Journal of Gastroenterology2011，17，4： | 3 |

| 18 | Hepatocellular carcinoma staging systems: Hong Kong liver cancer vs Barcelona clinic liver cancer in a Western population显示文摘BACKGROUND Despite being the world’s most widely used system for staging and therapeutic guidance in hepatocellular carcinoma(HCC)treatment,the Barcelona clinic liver cancer(BCLC)system has limitations,especially regarding intermediate-grade(BCLC-B)tumors.The recently proposed Hong Kong liver cancer(HKLC)staging system appears useful but requires validation in Western populations.AIM To evaluate the agreement between BCLC and HKLC staging on the management of HCC in a Western population,estimating the overall patient survival.METHODS This was a retrospective study of HCC patients treated at a university hospital in southern Brazil between 2011 and 2016.Demographic,clinical,and laboratory data were collected.HCC staging was carried out according to the HKLC and BCLC systems to assess treatment agreement.Overall survival was estimated based on the treatment proposed in each system.RESULTS A total of 519 HCC patients were assessed.Of these,178(34.3%)were HKLC-I;95(18.3%)HKLC-IIA;47(9.1%)HKLC-IIB;29(5.6%)HKLC-IIIA;30(5.8%)HKLCIIIB;75(14.4%)HKLC-IV;and 65(12.5%)HKLC-V.According to the BCLC,25(4.9%)were BCLC-0;246(47.4%)BCLC-A;107(20.6%)BCLC-B;76(14.6%)BCLCC;and 65(12.5%)BCLC-D.The general agreement between the two systems was 80.0%-BCLC-0 and HKLC-I(100%);BCLC-A and HKLC-I/HKLC-II(96.7%);BCLC-B and HKLC-III(46.7%);BCLC-C and HKLC-IV(98.7%);BCLC-D and HKLC-V(41.5%).When sub-classifying BCLC-A,HKLC-IIB,HKLC-IIIA and HKLC-IIIB stages according to the up-to-7 in/out criterion,13.4,66.0,100 and 36.7%,respectively,of the cases were classified as up-to-7 out.CONCLUSION In a Western population,the general agreement between the two systems was 80.0%,although in BCLC-B cases the agreement was low,suggesting that some individuals could be candidates for the curative treatment recommended by the HKLC.The authors suggest that the BCLC system should be routinely employed,although for BCLC-B cases it should be associated with the HKLC system. | Laura Bainy Rodrigues de Freitas Larisse Longo Deivid Santos Ivana Grivicich Mário Reis Alvares-da-Silva | 2019 | World Journal of Hepatology2019，11，9： | 3 |

| 20 | How to manage inflammatory bowel disease during the COVID-19 pandemic:A guide for the practicing clinician显示文摘Managing inflammatory bowel disease(IBD)during the coronavirus disease 2019(COVID-19)pandemic has been a challenge faced by clinicians and their patients,especially concerning whether to proceed with biologics and immunosuppressive agents in the background of a global outbreak of a highly contagious new coronavirus(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2).The knowledge about the impact of this virus on patients with IBD,although it is still scarce,is rapidly evolving.In particular,concerns surrounding medications’impact for IBD on the risk of acquiring SARS-CoV-2 infection or developing COVID-19,and potentially exacerbate viral replication and the COVID-19 course,are a current thinking of both practicing clinicians and providers caring for patients with IBD.Managing patients with IBD infected with SARS-CoV-2 depends on both the clinical activity of the IBD and the occasional development and severity of COVID-19.In this review,we summarize the current data regarding gastrointestinal involvement by SARS-CoV-2 and pharmacologic and surgical management for IBD concerning this infection,and the COVID-19 impact on both the patient's psychological functioning and endoscopy services,and we concisely summarize the telemedicine roles during the COVID-19 pandemic. | Júlio Maria Fonseca Chebli Natália Sousa Freitas Queiroz Adérson Omar Mourão Cintra Damião Liliana Andrade Chebli Márcia Henriques de Magalhães Costa Rogério Serafim Parra | 2021 | World Journal of Gastroenterology2021，27，11： | 2 |
