| 2 | Role of the Wnt/β-catenin pathway in gastric cancer: An indepth literature review显示文摘Gastric cancer remains one of the most common cancers worldwide and one of the leading cause for cancerrelated deaths. Gastric adenocarcinoma is a multifactorial disease that is genetically, cytologically and architecturally more heterogeneous than other gastrointestinal carcinomas.The aberrant activation of the Wnt/β-catenin signaling pathway is involved in the development and progression of a significant proportion of gastric cancer cases. This review focuses on the participation of the Wnt/b-catenin pathway in gastric cancer by offering an analysis of the relevant literature published in this field. Indeed, it is discussed the role of key factors in Wnt/β-catenin signaling and their downstream effectors regulating processes involved in tumor initiation, tumor growth, metastasis and resistance to therapy. Available data indicate that constitutive Wnt signalling resulting from Helicobacter pylori infection and inactivation of Wnt inhibitors(mainly by inactivating mutations and promoter hypermethylation) play an important role in gastric cancer. Moreover, a number of recent studies confirmed CTNNB1 and APC as driver genes in gastric cancer. The identification of specific membrane, intracellular, and extracellular components of the Wnt pathway has revealed potential targets for gastric cancer therapy. High-throughput 'omics' approaches will help in the search for Wnt pathway antagonist in the near future. | Miguel Angel Chiurillo | 2015 | World Journal of Experimental Medicine2015，5，2： | 58 |
| 3 | 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 |

| 5 | Laparoscopic colorectal surgery:current status andimplementation of the latest technological innovations显示文摘The introduction of laparoscopy is an example of surgical innovation with a rapid implementation in many areas of surgery. A large number of controlled studiesand meta-analyses have shown that laparoscopic colorectal surgery is associated with the same benefits than other minimally invasive procedures, including lesser pain, earlier recovery of bowel transit and shorter hospital stay. On the other hand, despite initial concerns about oncological safety, well-designed prospective randomized multicentre trials have demonstrated that oncological outcomes of laparoscopy and open surgery are similar. Although the use of laparoscopy in colorectal surgery has increased in recent years, the percentages of patients treated with surgery using minimally invasive techniques are still reduced and there are also substantial differences among centres. It has been argued that the limiting factor for the use of laparoscopic procedures is the number of surgeons with adequate skills to perform a laparoscopic colectomy rather than the tumour of patients' characteristics. In this regard, future efforts to increase the use of laparoscopic techniques in colorectal surgery will necessarily require more efforts in teaching surgeons. We here present a review of recent controversies of the use of laparoscopy in colorectal surgery, such as in rectal cancer operations, the possibility of reproducing complete mesocolon excision, and the benefits of intracorporeal anastomosis after right hemicolectomy. We also describe the results of latest innovations such as single incision laparoscopic surgery, robotic surgery and natural orifice transluminal endoscopic surgery for colon and rectal diseases. | Marta Pascual Silvia Salvans Miguel Pera | 2016 | World Journal of Gastroenterology2016，22，2： | 32 |
| 6 | Intestinal microbiota in health and disease: Role of bifidobacteria in gut homeostasis显示文摘The pool of microbes inhabiting our body is known as 'microbiota' and their collective genomes as 'microbiome'. The colon is the most densely populated organ in the human body, although other parts, such as the skin, vaginal mucosa, or respiratory tract, also harbour specific microbiota. This microbial community regulates some important metabolic and physiological functions of the host, and drives the maturation of the immune system in early life, contributing to its homeostasis during life. Alterations of the intestinal microbiota can occur by changes in composition(dysbiosis), function, or microbiota-host interactions and they can be directly correlated with several diseases. The only disease in which a clear causal role of a dysbiotic microbiota has been demonstrated is the case of Clostridium difficile infections. Nonetheless, alterations in composition and function of the microbiota have been associated with several gastrointestinal diseases(inflammatory bowel disease, colorectal cancer, or irritable bowel syndrome), as well as extra-intestinal pathologies, such as those affecting the liver, or the respiratory tract(e.g., allergy, bronchial asthma, and cystic fibrosis), among others. Species of Bifidobacterium genus are the normal inhabitants of a healthy human gut and alterations in number and composition of their populations is one of the most frequent features present in these diseases. The use of probiotics, including bifidobacteria strains, in preventive medicine to maintain a healthy intestinal function is well documented. Probiotics are also proposed as therapeutic agents for gastrointestinal disorders and other pathologies. The World Gastroenterology Organization recently published potential clinical applications for several probiotic formulations, in which species of lactobacilli are predominant. This review is focused on probiotic preparations containing Bifidobacterium strains, alone or in combination with other bacteria, which have been tested in human clinical studies. In spite of extensive literature on and research into this topic, the degree of scientific evidence of the effectiveness of probiotics is still insufficient in most cases. More effort need to be made to design and conduct accurate human studies demonstrating the efficacy of probiotics in the prevention, alleviation, or treatment of different pathologies. | Rafael Tojo Adolfo Suárez Marta G Clemente Clara G de los Reyes-Gavilán Abelardo Margolles Miguel Gueimonde Patricia Ruas-Madiedo | 2014 | World Journal of Gastroenterology2014，20，41： | 33 |
| 7 | Comparative review of vertebroplasty and kyphoplasty显示文摘The aim of this review is to compare the effectiveness of percutaneous vertebroplasty and kyphoplasty to treat pain and improve functional outcome from ver-tebral fractures secondary to osteoporosis and tumor conditions. In 2009, two open randomized controlled trials published in the New England Journal of Medicine questioned the value of vertebroplasty in treating ver-tebral compression fractures. Nevertheless, the prac-tice of physicians treating these conditions has barely changed. The objective of this review is to try to clarify the most important issues, based on our own experi-ence and the reported evidence about both techniques, and to guide towards the most appropriate choice of treatment of vertebral fractures, although many ques-tions still remain unanswered. | Ferno Ruiz Santiago Alicia Santiago Chinchilla Luis Guzmán álvarez Antonio Luis Pérez Abela Maria del Mar Castellano García Miguel Pajares López | 2014 | World Journal of Radiology2014，6，6： | 30 |

| 10 | Qualitative and quantitative analyses of the bifidobacterial microbiota in the colonic mucosa of patients with colorectal cancer, diverticulitis and inflammatory bowel disease显示文摘AIM: To characterize the bifidobacterial microbiota of the colonic mucosa in patients with colon cancer, inflammatory bowel disease or diverticulitis. METHODS: A sample of the distal colonic mucosa was taken during surgery from a total of 34 patients, twenty-one with diagnosed colorectal cancer, nine with diverticulitis and four with inflammatory bowel disease, requiring surgery for their condition. Bacterial DNA was extracted from the resected mucosal samples and bifidobacterial mucosa-associated microbiota was qualitatively and quantitatively determined by means of qualitative and quantitative PCR. RESULTS: Bifidobacteria were found in 100% of the samples from patients with diverticulitis or IBD and a 76% of those suffering colon cancer. The species B. longum and B. bifidum were the most widely found, followed by B. animalis, B. catenulatum and B. adolescentis. B. breve, B. dentium and B. angulatum were not detected in any sample. A significantly higher occurrence of B. longum was observed in patients with diverticulitis than in those with colon cancer or IBD (100%, 62% and 75%, respectively, P < 0.05). Similar results were obtained for B. animalis (56%, 0% and 25%, P < 0.05), while B. adolescentis was only found in the mucosa from patients with colon cancer (5 out of 21, 24%). At the quantitative level, patients with colon cancer or IBD showed lower counts of total Bifidobacterium (4.94 and 5.91 vs 6.96 log Cells/sample, respectively, P < 0.05) and of the species B. longum (4.05 and 4.79 vs 6.76, P < 0.05) than those with diverticulitis. CONCLUSION: Aberrancies in mucosa associated microbiota are present in different intestinal diseases. This may indicate a role of the microbiota in the pathogenesis of these diseases. | Miguel Gueimonde Arthur Ouwehand Heikki Huhtinen Eeva Salminen Seppo Salminen | 2007 | World Journal of Gastroenterology2007，13，29： | 25 |
| 11 | Emerging role of microRNAs in liver diseases显示文摘MicroRNAs are a class of small non-coding RNAs that are found in plants, animals, and some viruses. They modulate the gene function at the post-transcriptional level and act as a fine tuner of various processes, such as development, proliferation, cell signaling, and apopto-sis. They are associated with different types and stages of cancer. Recent studies have shown the involvement of microRNAs in liver diseases caused by various factors, such as Hepatitis C, Hepatitis B, metabolic disorders, and by drug abuse. This review highlights the role of microRNAs in liver diseases and their potential use as therapeutic molecules. | Shashi Bala Miguel Marcos Gyongyi Szabo | 2009 | World Journal of Gastroenterology2009，15，45： | 25 |
| 12 | TCP14 and TCP15 Mediate the Promotion of Seed Germination by Gibberellins in Arabidopsis thaliana显示文摘Dear Editor, Seed germination is a major developmental transition in a plant's life that involves the concerted action of several genetic and physiological pathways (Holdsworth et al.,2008),and mostly consists of the resumption of embryo growth after a long quiescence imposed during seed maturation.In mature seeds,germination is repressed by abscisic acid (ABA),while favorable environmental conditions promote gibberellin (GA) biosynthesis and decrease ABA (Holdsworth et al.,2008).The increase in GA levels is essential for the rupture of testa and endosperm (Lee et al.,2002).The activation of cell division in the embryo is an integral part of germination that precedes the protrusion of the root through the seed coat.In Arabidopsis,this activation has been linked to significant early changes in the expression of cell-cycle elements (Masubelele et al.,2005). | Francesca Resentini Amelia Felipo-Benavent Lucia Colombo Miguel A.

| 13 | Different profile of cytokine synthesis according to the severity of acute pancreatitis显示文摘AIM: To evaluate the cellular synthetic ability of cytokines involved in pro- and anti-inflammatory reactions in patients with AP.METHODS: Sixty-seven patients with AP (16 severe,51 mild) and 10 controls were included in the study.Cultures of whole blood were performed in samples obtained within the first 72 h from the onset of pain.Serum levels of interleukins (IL) 6, 8, 10, and TNF-α were measured at baseline and in the supernatant of cultures with (functional reserve) or without stimulation with phytohemaglutinin.RESULTS: Basal levels of cytokines were significantly higher in patients with severe AP. A significant increase of all pro-inflammatory cytokines vs basal levels was observed in the supernatant after 24 h of whole blood cultures in patients, but not in controls. In contrast, IL-10 increased significantly in the supernatant of cultures only in patients with mild AP. Cells showed a statistically significant functional reserve for all IL in patients with mild, but only for pro-inflammatory cytokines in patients with severe AP.CONCLUSION: A marked activation of immune system may be observed in patients with AP, being balanced between pro- and anti-inflammatory cytokines in patients with mild but not severe AP. A reduced functional reserve for the synthesis of IL-10 may be observed in patients with severe AP, which might lead to a worst prognosis. | Raquel Laveda Juan Martínez Carlos Mu■oz Juan Carlos Penalva Jesus Sáez Germán Belda Salvador Navarro Faust Feu Anton Mas José Ma Palazón José Sánchez-Payá José Such Miguel Pérez-Mateo | 2005 | World Journal of Gastroenterology2005，11，34： | 24 |
| 14 | Risk factors and classifications of hilar cholangiocarcinoma显示文摘Cholangiocarcinoma is the second most common primary malignant tumor of the liver.Perihilar cholangiocarcinoma or Klatskin tumor represents more than 50% of all biliary tract cholangiocarcinomas.A wide range of risk factors have been identified among patients with Perihilar cholangiocarcinoma including advanced age,male gender,primary sclerosing cholangitis,choledochal cysts,cholelithiasis,cholecystitis,parasitic infection(Opisthorchis viverrini and Clonorchis sinensis),inflammatory bowel disease,alcoholic cirrhosis,nonalcoholic cirrhosis,chronic pancreatitis and metabolic syndrome.Various classifications have been used to describe the pathologic and radiologic appearance of cholangiocarcinoma.The three systems most commonly used to evaluate Perihilar cholangiocarcinoma are the Bismuth-Corlette(BC) system,the Memorial Sloan-Kettering Cancer Center and the TNM classification.The BC classification provides preoperative assessment of local spread.The Memorial Sloan-Kettering cancer center proposes a staging system according to three factors related to local tumor extent:the location and extent of bile duct involvement,the presence or absence of portal venous invasion,and the presence or absence of hepatic lobar atrophy.The TNM classification,besides the usual descriptors,tumor,node and metastases,provides additional information concerning the possibility for the residual tumor(R) and the histological grade(G).Recently,in 2011,a new consensus classification for the Perihilar cholangiocarcinoma had been published.The consensus was organised by the European Hepato-PancreatoBiliary Association which identified the need for a new staging system for this type of tumors.The classification includes information concerning biliary or vascular(portal or arterial) involvement,lymph node status or metastases,but also other essential aspects related to the surgical risk,such as remnant hepatic volume or the possibility of underlying disease. | Miguel Angel Suarez-Munoz Jose Luis Fernandez-Aguilar Belinda Sanchez-Perez Jose Antonio Perez-Daga Beatriz Garcia-Albiach Ysabel Pulido-Roa Naiara Marin-Camero Julio Santoyo-Santoyo | 2013 | World Journal of Gastrointestinal Oncology2013，5，7： | 23 |
| 15 | 高含硫天然气脱硫操作条件对能耗影响的模拟研究显示文摘采用流程模拟技术分析了高含硫天然气脱硫工艺操作条件,如原料气处理量、吸收塔温度、吸收塔压力、吸收塔板数、再生塔温度对脱硫能耗的影响,并通过灵敏度分析比较了各操作条件对脱硫能耗的影响力大小。结果表明,高含硫天然气中酸性组分浓度高,为满足净化要求需增大溶液循环量,因此带动公用工程消耗增加,脱硫能耗比常规含硫天然气脱硫情况显著增加。在操作中,提高吸收塔温度、再生塔温度和原料气处理量均会引起脱硫能耗升高,而降低吸收塔压力、减少吸收塔板数可降低脱硫能耗。由于醇胺溶液再生耗能占脱硫总能耗绝大部分,故制定节能措施应重点考虑再生塔温度控制,蒸汽、凝结水以及净化系统余压、余热资源的合理利用。 | 邱奎 安鹏飞 杨馥宁 诸林 KIM Sungyoung BAGAJEWICZ Miguel | 2012 | 石油学报(石油加工)2012，28，6： | 23 |
| 16 | The role of aluminum sensing and signaling in plant aluminum resistance显示文摘As researchers have gained a better understanding in recent years into the physiological, molecular, and genetic basis of how plants deal with aluminum(Al) toxicity in acid soils prevalent in the tropics and sub‐tropics, it has become clear that an important component of these responses is the triggering and regulation of cellular pathways and processes by Al. In this review of plant Al signaling, we begin by summarizing the understanding of physiological mechanisms of Al resistance, which first led researchers to realize that Al stress induces gene expression and modifies protein function during the activation of Al resistance responses. Subsequently, an overview of Al resistance genes and their function provides verification that Al induction of gene expression plays a major role in Al resistance in many plant species. More recent research into the mechanistic basis for Al‐induced transcriptional activation of resistance genes has led to the identification of several transcription factors as well as cis‐elements in the promoters of Al resistance genes that play a role in greater Al‐induced gene expression as well as higher constitutive expression of resistance genes in some plant species. Finally,the post‐transcriptional and translational regulation of Al resistance proteins is addressed, where recent research has shown that Al can both directly bind to and alter activity of certain organic acid transporters, and also influence Al resistance proteins indirectly, via protein phosphorylation. | Jiping Liu Miguel A.Piros Leon V.Kochian | 2014 | Journal of Integrative Plant Biology2014，56，3： | 23 |

| 19 | Device-associated infection rates, mortality, length of stay and bacterial resistance in intensive care units in Ecuador: International Nosocomial Infection Control Consortium's findings显示文摘AIM To report the results of the International Nosocomial Infection Control Consortium(INICC) study conducted in Quito, Ecuador.METHODS A device-associated healthcare-acquired infection(DAHAI) prospective surveillance study conducted from October 2013 to January 2015 in 2 adult intensive care units(ICUs) from 2 hospitals using the United States Centers for Disease Control/National Healthcare Safety Network(CDC/NHSN) definitions and INICC methods. RESULTS We followed 776 ICU patients for 4818 bed-days. The central line-associated bloodstream infection(CLABSI) rate was 6.5 per 1000 central line(CL)-days, the ventilator-associated pneumonia(VAP) rate was 44.3 per 1000 mechanical ventilator(MV)-days, and the catheterassociated urinary tract infection(CAUTI) rate was 5.7 per 1000 urinary catheter(UC)-days. CLABSI and CAUTI rates in our ICUs were similar to INICC rates [4.9(CLABSI) and 5.3(CAUTI)] and higher than NHSN rates [0.8(CLABSI) and 1.3(CAUTI)]- although device use ratios for CL and UC were higher than INICC and CDC/NSHN's ratios. By contrast, despite the VAP rate was higher than INICC(16.5) and NHSN's rates(1.1), MV DUR was lower in our ICUs. Resistance of A. baumannii to imipenem and meropenem was 75.0%, and of Pseudomonas aeruginosa to ciprofloxacin and piperacillin-tazobactam was higher than 72.7%, all them higher than CDC/NHSN rates. Excess length of stay was 7.4 d for patients with CLABSI, 4.8 for patients with VAP and 9.2 for patients CAUTI. Excess crude mortality in ICUs was 30.9% for CLABSI, 14.5% for VAP and 17.6% for CAUTI. CONCLUSION DA-HAI rates in our ICUs from Ecuador are higher than United States CDC/NSHN rates and similar to INICC international rates. | Estuardo Salgado Yepez Maria M Bovera Victor D Rosenthal Hugo A González Flores Leonardo Pazmino Francisco Valencia Nelly Alquinga Vanessa Ramirez Edgar Jara Miguel Lascano Veronica Delgado Cristian Cevallos Gasdali Santacruz Cristian Pelaéz Celso Zaruma Diego Barahona Pinto | 2017 | World Journal of Biological Chemistry2017，8，1： | 23 |
| 20 | Clinical value of rapid urine trypsinogen-2 test strip, urinary trypsinogen activation peptide, and serum and urinary activation peptide of carboxypeptidase B in acute pancreatitis显示文摘AIM: To assess the usefulness of urinary trypsinogen-2 test strip, urinary trypsinogen activation peptide (TAP),and serum and urine concentrations of the activation peptide of carboxypeptidase B (CAPAP) in the diagnosisof acute pancreatitis.METHODS: Patients with acute abdominal pain and hospitalized within 24 h after the onset of symptoms were prospectively studied. Urinary trypsinogen-2 was considered positive when a clear blue line was observed (detection limit 50 μg/L). Urinary TAP was measured using a quantitative solid-phase ELISA, and serum and urinary CAPAP by a radioimmunoassay method.RESULTS: Acute abdominal pain was due to acute pancreatitis in 50 patients and turned out to be extrapancreatic in origin in 22 patients. Patients with acute pancreatitis showed significantly higher median levels of serum and urinary CAPAP levels, as well as amylase and lipase than extrapancreatic controls. Median TAP levels were similar in both groups. The urinary trypsinogen-2 test strip was positive in 68% of patients with acute pancreatitis and 13.6% in extrapancreatic controls (P<0.01). Urinary CAPAP was the most reliable test for the diagnosis of acute pancreatitis (sensitivity 66.7%, specificity 95.5%, positive and negative predictive values 96.6% and 56.7%, respectively), with a 14.6 positive likelihood ratio for a cut-off value of 2.32 nmol/L.CONCLUSION: In patients with acute abdominal pain,hospitalized within 24 h of symptom onset, CAPAP in serum and urine was a reliable diagnostic marker of acute pancreatitis. Urinary trypsinogen-2 test strip showed a clinical value similar to amylase and lipase.Urinary TAP was not a useful screening test for the diagnosis of acute pancreatitis. | Jesús Sáez Juan Martínez Celia Trigo José Sánchez-Payá Luis Compay Raquel Laveda Pilar Grió Cristina García Miguel Pérez-Mateo | 2005 | World Journal of Gastroenterology2005，11，46： | 21 |
