| 1 | WJD 5^(th) Anniversary Special Issues(2): Type 2 diabetes Inflammation in diabetic kidney disease显示文摘Diabetes mellitus entails significant health problems worldwide.The pathogenesis of diabetes is multifactorial,resulting from interactions of both genetic and environmental factors that trigger a complex network of pathophysiological events,with metabolic and hemodynamic alterations.In this context,inflammation has emerged as a key pathophysiology mechanism.New pathogenic pathways will provide targets for prevention or future treatments.This review will focus on the implications of inflammation in diabetes mellitus,with special attention to inflammatory cytokines. | Patricia M García-García María A Getino-Melian Virginia Domínguez-Pimentel Juan F Navarro-Gonzalez | 2014 | World Journal of Diabetes2014，5，4： | 26 |
| 2 | Plasma betatrophin levels in patients with liver cirrhosis显示文摘AIM: To investigate the plasma levels of betatrophin in patients with cirrhosis.METHODS: Forty patients diagnosed at the clinic with liver cirrhosis according to biological, ultrasonographic,or histological criteria were included.The severity of cirrhosis was classified according to Pugh's modification of Child's classification and MELD score. Insulin resistance(IR) was assessed by the Homeostasis Model Assessment. A total of 20 patients showed a MELD score higher than 14. The control group consisted in 15 sex-and aged-matched subjects.Fasting blood samples were obtained for subsequent analysis. Serum insulin was determined by Liaison automated immune chemiluminiscence assay(DiaSorin S.p.A.) using a sandwich assay. The sensitivity of the assay was 0.2 μU/mL. The intra and interassay variation coefficients were < 4% and < 10%,respectively. The normal values were between 2 and17 μU/mL. Human active betatrophin was analyzed by specific quantitative sandwich ELISA(Aviscera Bioscience). The sensitivity of the assay was 0.4 ng/mL, and the intra and interassay reproducibility were< 6% and < 10%, respectively.RESULTS: Plasma betatrophin levels were significantly increased in patients with cirrhosis compared with those in healthy subjects(P = 0.0001). Betatrophin levels were also associated with disease severity, being higher in Child-Pugh C patients compared to Child-Pugh B(P< 0.0005) and in patients who displayed a MELD score higher than 14 points compared to patients with lower punctuation(P = 0.01). In addition, we found a positive correlation between plasma betatrophin levels and the severity of cirrhosis according to Child-Pugh classification(r = 0.53; P < 0.01) or MELD score(r = 0.45; P <0.01). In the overall cohort, a moderate correlation between serum betatrophin and plasmatic bilirrubin(r= 0.39; P < 0.01) has been observed, as well as an inverse correlation between betatrophin and albumin(r =-0.41; P < 0.01) or prothrombin time(r =-0.44;P <0.01). Moreover, insulin resistance was observed in82.5% of the cirrhotic patients. In this group of patients,betatrophin levels were significantly higher than those in the group of patients without IR(P < 0.05).CONCLUSION: Plasma betatrophin is increased in patients with cirrhosis. This increase is related to the severity of cirrhosis, as well as with the emergence of insulin resistance. | Maria Teresa Arias-Loste Maria Teresa García-Unzueta Susana Llerena Paula Iruzubieta Angela Puente Joaquín Cabezas Carmen Alonso Antonio Cuadrado José Antonio Amado Javier Crespo Emilio Fábrega | 2015 | World Journal of Gastroenterology2015，21，37： | 9 |
| 3 | Ultrafine Grained HSLA Steels for Cold Forming显示文摘The industrial level production of ultrafine grained(or ultrafine ferrite)ferrous alloys was investigated through three examples of steels that complied with the EN 10149-2 Euronorm and were produced by advanced controlled hot rolling techniques.The steel samples were tension tested and chemically analyzed,and the microstructure was evaluated through quantitative metallographic techniques to determine parameters such as yield stress,amount of microalloying elements,strain hardening coefficient,grain size,and grain size distribution.These steels were microalloyed with Ti,Nb,and Mn with ASTM grain sizes of approximately 13-15.The careful control of chemical composition and deformation during production,giving a specific attention to the deformation sequences,austenite non-recrystallization temperatures and allotropic transformations during cooling,are indispensable to obtain steels with an adequate strain hardening coefficient that allows cold working operations such as bending,stretching or drawing. | R González J O García M A Barbés M J Quintana L F Verdeja J I Verdeja | 2010 | Journal of Iron and Steel Research(International)2010，17，10： | 7 |
| 4 | SIRT3-mediated inhibition of FOS through histone H3 deacetylation prevents cardiac fibrosis and inflammation显示文摘Sirtuin 3(SIRT3)is a deacetylase that modulates proteins that control metabolism and protects against oxidative stress.Modulation of SIRT3 activity has been proposed as a promising therapeutic target for ameliorating metabolic diseases and associated cardiac disturbances.In this study,we investigated the role of SIRT3 in inflammation and fibrosis in the heart using male mice with constitutive and systemic deletion of SIRT3 and human cardiac AC16 cells.SIRT3 knockout mice showed cardiac fibrosis and inflammation that was characterized by augmented transcriptional activity of AP-1.Consistent with this,SIRT3 overexpression in human and neonatal rat cardiomyocytes partially prevented the inflammatory and profibrotic response induced by TNF-α.Notably,these effects were associated with a decrease in the mRNA and protein levels of FOS and the DNA-binding activity of AP-1.Finally,we demonstrated that SIRT3 inhibits FOS transcription through specific histone H3 lysine K27 deacetylation at its promoter.These findings highlight an important function of SIRT3 in mediating the often intricate profibrotic and proinflammatory responses of cardiac cells through the modulation of the FOS/AP-1 pathway.Since fibrosis and inflammation are crucial in the progression of cardiac hypertrophy,heart failure,and diabetic cardiomyopathy,our results point to SIRT3 as a potential target for treating these diseases. | Xavier Palomer MSilvia Román-Azcona Javier Pizarro-Delgado Ana Planavila Francesc Villarroya Brenda Valenzuela-Alcaraz Fátima Crispi Álvaro Sepúlveda-Martínez Irene Miguel-Escalada Jorge Ferrer JFrancisco Nistal Raquel García Mercy MDavidson Emma Barroso Manuel Vázquez-Carrera | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 7 |
| 5 | Xeroderma pigmentosum group D 751 polymorphism as a predictive factor in resected gastric cancer treated with chemo-radiotherapy显示文摘AIM: To evaluate the potential association of xeroderma pigmentosum group D (XPD) codon 751 variant with outcome after chemo-radiotherapy in patients with resected gastric cancer. METHODS: We used PCR-RFLP to evaluate the genetic XPD Lys751Gln polymorphisms in 44 patients with stage Ⅲ (48%) and Ⅳ (20%) gastric cancer treated with surgery following radiation therapy plus 5-fluorouracil/ leucovorin based chemotherapy. RESULTS: Statistical analysis showed that 75% (12 of 16) of relapse patients showed Lys/Lys genotype more frequently (P = 0.042). The Lys polymorphism was an independent predictor of high-risk relapse-free survival from Cox analysis (HR: 3.07, 95% CI: 1.07-8.78, P = 0.036) and Kaplan-Meir test (P = 0.027, log-rank test). CONCLUSION: XPD Lys751Gln polymorphism may be an important marker in the prediction of clinical outcome to chemo-radiotherapy in resected gastric cancer patients. | RN Zárate R F Arias E Bandres E Cubedo R Malumbres J García-Foncillas | 2006 | World Journal of Gastroenterology2006，12，37： | 7 |
| 6 | Incidence, risk factors and outcome of de novo tumors in liver transplant recipients focusing on alcoholic cirrhosis显示文摘Orthotopic liver transplantation(OLT) is an established life-saving procedure for alcoholic cirrhotic(AC) patients, but the incidence of de novo tumors ranges between 2.6% and 15.7% and is significantly increased in comparison with patients who undergo OLT for other etiologies. Tobacco, a known carcinogen, has been reported to be between 52% and 83.3% in AC patients before OLT. Other risk factors that contribute to the development of malignancies are dose-dependent immunosuppression, advanced age, viral infections, sun exposure, and premalignant lesions(inflammatory bowel disease, Barrett's esophagus). A significantly more frequent incidence of upper aerodigestive(UAD) tract, lung, skin, and kidney-bladder tumors has been found in OLT recipients for AC in comparison with other etiologies. Liver transplant recipients who develop de novo non-skin tumors have a decreased long-term survival rate compared with controls. This significantly lower survival rate is more evident in AC recipients who develop UAD tract or lung tumors after OLT mainly because the diagnosis is usually performed at an advanced stage. All transplant candidates, especially AC patients, should be encouraged to cease smoking and alcohol consumption in the pre- and postOLT periods, use skin protection, avoid sun exposure and over-immunosuppression, and have a yearly otopharyngolaryngeal exploration and chest computed tomography scan in order to prevent or reduce the incidence of de novo malignancies. Although still under investigation, substitution of calcineurin inhibitors for sirolimus or everolimus may reduce the incidence of de novo tumors after OLT. | Carlos Jiménez-Romero Iago Justo-Alonso Félix Cambra-Molero Jorge Calvo-Pulido álvaro García-Sesma Manuel Abradelo-Usera Oscar Caso-Maestro Alejandro Manrique-Municio | 2015 | World Journal of Hepatology2015，7，7： | 6 |

| 8 | Structural studies of BaTiO_3:Er^(3+) and BaTiO_3:Yb^(3+) powders synthesized by hydrothermal method显示文摘Erbium and ytterbium doped barium titanate nanopowders were prepared using the hydrothermal method. A barium titanate structure doped with rare earth ions manifested new characteristics and improved the field of application of optical devices such as trichromatic tubes, LCD displays, lamps, and infrared lasers. In this work, BaTiO3:Er3+ and BaTiO3:Yb3+ were prepared using barium chloride [BaCl2], titanium butoxide [C16H36O4Ti], erbium chloride [ErCl3] and ytterbium chloride [YbCl3] as precursors. Anhydrous methanol was employed as a solvent. Metallic potassium was used to promote solubility in the system and increase the pH to 13. This method yielded the formation of a predominantly cubic structure in both Er3+ and Yb3+ doped BaTiO3 powders. Characteristic bondings of BaTiO3 were observed with FT-IR spectroscopy. The predominantly cubic structure was confirmed by X-ray diffraction and micro-Raman analyses. The particle size(~30 nm) was estimated using the Scherrer equation and X-ray diffraction data. The results were presented and discussed. | Garrido-Hernández A García-Murillo A Carrillo-Romo F de J Cruz-Santiago L A Chadeyron G Morales-Ramírez A de J Velumani S | 2014 | Journal of Rare Earths2014，32，11： | 3 |
| 9 | Double-layer graphene for enhanced tunable infrared plasmonics显示文摘Graphene is emerging as a promising material for photonic applications owing to its unique optoelectronic properties.Graphene supports tunable,long-lived and extremely confined plasmons that have great potential for applications such as biosensing and optical communications.However,in order to excite plasmonic resonances in graphene,this material requires a high doping level,which is challenging to achieve without degrading carrier mobility and stability.Here,we demonstrate that the infrared plasmonic response of a graphene multilayer stack is analogous to that of a highly doped single layer of graphene,preserving mobility and supporting plasmonic resonances with higher oscillator strength than previously explored single-layer devices.Particularly,we find that the optically equivalent carrier density in multilayer graphene is larger than the sum of those in the individual layers.Furthermore,electrostatic biasing in multilayer graphene is enhanced with respect to single layer due to the redistribution of carriers over different layers,thus extending the spectral tuning range of the plasmonic structure.The superior effective doping and improved tunability of multilayer graphene stacks should enable a plethora of future infrared plasmonic devices with high optical performance and wide tunability. | Daniel Rodrigo Andreas Tittl Odeta Limaj F Javier García de Abajo Valerio Pruneri Hatice Altug | 2017 | Light(Science & Applications)2017，6，1： | 3 |
| 10 | Liver fat deposition and mitochondrial dysfunction in morbid obesity:An approach combining metabolomics with liver imaging and histology显示文摘AIM: To explore the usefulness of magnetic resonance imaging(MRI) and spectroscopy(MRS) for assessment of non-alcoholic fat liver disease(NAFLD) as compared with liver histological and metabolomics findings. METHODS: Patients undergoing bariatric surgery following procedures involved in laparoscopic sleeve gastrectomy were recruited as a model of obesityinduced NAFLD in an observational, prospective, singlesite, cross-sectional study with a pre-set duration of 1 year. Relevant data were obtained prospectively and surrogates for inflammation, oxidative stress and lipid and glucose metabolism were obtained through standard laboratory measurements. To provide reliable data from MRI and MRS, novel procedures were designed to limit sampling variability and other sources of error using a 1.5T Signa HDx scanner and protocols acquired from the 3D or 2D Fat SAT FIESTA prescription manager. We used our previously described 1H NMRbased metabolomics assays. Data were obtained immediately before surgery and after a 12-mo period including histology of the liver and measurement of metabolites. Values from 1H NMR spectra obtained after surgery were omitted due to technical limitations.RESULTS: MRI data showed excellent correlation with the concentration of liver triglycerides, other hepatic lipid components and the histological assessment, w h i c h e xc l u d e d t h e p r e s e n c e o f n o n-a l c o h o l i c steatohepatitis(NASH). MRI was sufficient to follow up NAFLD in obese patients undergoing bariatric surgery and data suggest usefulness in other clinical situations. The information provided by MRS replicated that obtained by MRI using the-CH3 peak(0.9 ppm), the-CH2- peak(1.3 ppm, mostly triglyceride) and the-CH=CH- peak(2.2 ppm). No patient depicted NASH. After surgery all patients significantly decreased their body weight and steatosis was virtually absent even in patients with previous severe disease. Improvement was also observed in the serum concentrations of selected variables. The most relevant findings using metabolomics indicate increased levels of triglyceride and monounsaturated fatty acids in severe steatosis but those results were accompanied by a significant depletion of diglycerides, polyunsaturated fatty acids, glucose-6-phosphate and the ATP/AMP ratio. Combined data indicated the coordinated action on mitochondrial fat oxidation and glucose transport activity and may support the consideration of NAFLD as a likely mitochondrial disease. This concept may helpto explain the dissociation between excess lipid storage in adipose tissue and NAFLD and may direct the search for plasma biomarkers and novel therapeutic strategies. A limitation of our study is that data were obtained in a relatively low number of patients.CONCLUSION: MRI is sufficient to stage NAFLD in obese patients and to assess the improvement after bariatric surgery. Other data were superfluous for this purpose. | Nahum Calvo Raúl Beltrán-Debón Esther Rodríguez-Gallego Anna Hernández-Aguilera Maria Guirro Roger Mariné-Casadó Lidón Millá Josep M Alegret Fàtima Sabench Daniel del Castillo María Vinaixa Miguelàngel Rodríguez Xavier Correig Roberto García-álvarez Javier A Menendez Jordi Camps Jorge Joven | 2015 | World Journal of Gastroenterology2015，21，24： | 2 |

| 12 | Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19. | Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral | 2021 | Cellular & Molecular Immunology2021，18，9： | 2 |
| 13 | Disordered eating behaviors in type 1 diabetic patients显示文摘Patients with type 1 diabetes mellitus are at high risk for disordered eating behaviors (DEB). Due to the fact that type 1 diabetes mellitus is one of the most common chronic illnesses of childhood and adolescence, the coexistence of eating disorders (ED) and diabetes often affects adolescents and young adults. Since weight management during this state of development can be especially diff icult for those with type 1 diabetes, some diabetics may restrict or omit insulin, a condition known as diabulimia, as a form of weight control. It has been clearly shown that ED in type 1 diabetics are associated with impaired metabolic control, more frequent episodes of ketoacidosis and an earlier than expected onset of diabetes-related microvascular complications, particularly retinopathy. The management of these conditions requires a multidisciplinary team formed by an endocrinologist/diabetologist, a nurse educator, a nutritionist, a psychologist and, frequently, a psychiatrist. The treatment of type 1 diabetes patients with DEB and ED should have the following compo- nents: diabetes treatment, nutritional management and psychological therapy. A high index of suspicion of the presence of an eating disturbance, particularly among those patients with persistent poor metabolic control, repeated episodes of ketoacidosis and/or weight andshape concerns are recommended in the initial stage of diabetes treatment, especially in young women. Given the extent of the problem and the severe medical risk associated with it, more clinical and technological research aimed to improve its treatment is critical to the future health of this at-risk population. | Alejandra Larraaga Ricardo V García-Mayor María F Docet | 2011 | World Journal of Diabetes2011，2，11： | 2 |
| 14 | Analyzing predictors of graft survival in patients undergoing liver transplantation with donors aged 70 years and over显示文摘AIM To increase the number of available grafts.METHODS This is a single-center comparative analysis performed between April 1986 and May 2016. Two hundred and twelve liver transplantation(LT) were performed with donors ≥ 70 years old(study group). Then, we selected the first cases that were performed with donors < 70 years old immediately after the ones that were performed with donors ≥ 70 years old(control group).RESULTS Graft and patient survivals were similar between both groups without increasing the risk of complications, especially primary non-function, vascular complications and biliary complications. We identified 5 risk factors as independent predictors of graft survival: recipient hepatitis C virus(HCV)-positivity [hazard ratio(HR) = 2.35; 95% confidence interval(CI): 1.55-3.56; P = 0.00]; recipient age(HR = 1.04; 95%CI: 1.02-1.06; P = 0.00); donor age X model for end-stage liver disease(D-MELD)(HR = 1.00; 95%CI: 1.00-1.00; P = 0.00); donor value of serum glutamic-pyruvic transaminase(HR = 1.00; 95%CI: 1.00-1.00; P = 0.00); and donor value of serum sodium(HR = 0.96; 95%CI: 0.94-0.99; P = 0.00). After combining D-MELD and recipient age we obtained a new scoring system that we called DR-MELD(donor age X recipient age X MELD). Graft survival significantly decreased in patients with a DR-MELD score ≥ 75000, especially in HCV patients(77% vs 63% at 5 years in HCV-negative patients, P = 0.00; and 61% vs 25% at 5 years in HCV-positive patients; P = 0.00). CONCLUSION A DR-MELD ≥ 75000 must be avoided in order to obtain the best results in LT with donors ≥ 70 years old. | Oscar Caso-Maestro Carlos Jiménez-Romero Iago Justo-Alonso Jorge Calvo-Pulido David Lora-Pablos Alberto Marcacuzco-Quinto Félix Cambra-Molero Alvaro García-Sesma Marina Pérez-Flecha Carlos Munoz- Arce Carmelo Loinaz-Segurola Alejandro Manrique-Municio | 2018 | World Journal of Gastroenterology2018，24，47： | 2 |
| 15 | Software Project Management Approaches for Global Software Development: A Systematic Mapping Study显示文摘Global Software Development(GSD) is a well established field of software engineering with the benefits of a global environment. Software Project Management(SPM) plays a key role in the success of GSD. As a result, the need has arisen to study and evaluate the downsides of SPM for GSD, to thereby pave the way for the development of new methods, techniques, and tools with which to tackle them. This paper aims to identify and classify research on SPM approaches for GSD that are available in the literature, to identify their current weaknesses and strengths, and to analyze their applications in industry. We performed a Systematic Mapping Study(SMS) based on six classification criteria. Eighty-four papers were selected and analyzed. The results indicate that interest in SPM for GSD has been increasing since 2006. As a class of approaches, the most frequently reported methods(40%) are those used for coordination, planning, and monitoring, along with estimation techniques that can be used to better match a distributed project. SPM for GSD requires further investigation by researchers and practitioners, particularly with respect to cost and time estimations. These findings will help overcome the challenges that must to be considered in future SPM research for GSD, especially regarding collaboration and time-zone differences. | Manal El Bajta Ali Idri Joaquín Nicolás Ros José Luis Fernández-Alemán Juan Manuel Carrillo de Gea Félix García Ambrosio Toval | 2018 | Tsinghua Science and Technology2018，23，6： | 2 |
