| 1 | Vitamin D deficiency in chronic liver disease显示文摘Vitamin D is an important secosteroid hormone with known effect on calcium homeostasis,but recently there is increasing recognition that vitamin D also is involved in cell proliferation and differentiation,has immunomodulatory and anti-inflammatory properties.Vitamin D deficiency has been frequently reported in many causes of chronic liver disease and has been associated with the development and evolution of non-alcoholic fatty liver disease(NAFLD)and chronic hepatitis C(CHC)virus infection.The role of vitamin D in the pathogenesis of NAFLD and CHC is not completely known,but it seems that the involvement of vitamin D in the activation and regulation of both innate and adaptive immune systems and its antiproliferative effect may explain its importance in these liver diseases.Published studies provide evidence for routine screening for hypovitaminosis D in patients with liver disease.Further prospectives studies demonstrating the impact of vitamin D replacement in NAFLD and CHC are required. | Paula Iruzubieta lvaro Terán Javier Crespo Emilio Fábrega | 2014 | World Journal of Hepatology2014，6，12： | 13 |
| 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 | Impact of an acute hemodynamic response-guided protocol for primary prophylaxis of variceal bleeding显示文摘AIM To evaluate the long-term outcome of an acute hemodynamic response-guided protocol in which acute responders to intravenous propranolol received traditional nonselective beta-blockers(NSBBs) and acute nonresponders received carvedilol.METHODS Retrospective review of a protocol for primary prophylaxis of variceal bleeding guided by the acute hemodynamic response to intravenous propranolol. Fifty-two acute responders treated with traditional NSBB(i.e. propranolol or nadolol) were compared with 24 acute nonresponders receiving carvedilol. A second hemodynamic study was performed in 27 and 13 patients, respectively. The primary endpoint was development of first or further decompensation. Secondary endpoints included death from any cause, association between acute and chronic hemodynamic response, and baseline clinical and laboratory variables related to the acute hemodynamic response.RESULTS Acute responders and acute nonresponders presented similar 1, 2, and 3-year probabilities of first decompensation(NSBB: 0%, 13.7%, 26.1% vs carvedilol: 0%, 20%, 20%, P = 0.968) or further decompensation(21.2%, 26.1%, 40.9% vs 21.2%, 50.0%, 50.0%, P = 0.525). A previous episode of hepatic encephalopathy was the only independent predictor of decompensation [hazard ratio(95% confidence interval): 8.03(2.76-23.37)]. Mortality rates were similar in acute responders and acute nonresponders with compensated(P = 0.428) or decompensated cirrhosis(P = 0.429). No clinical, laboratory, endoscopic or hemodynamic parameter predicted the acute hemodynamic response. In patients receiving traditional NSBB, the acute and chronic changes of hepatic venous pressure gradient were correlated(r = 0.59, P = 0.001). Up to 69.2% of acute nonresponders gained chronic response with carvedilol.CONCLUSION Early identification and treatment with carvedilol of acute nonresponders to intravenous propranolol improves the clinical outcome of this high-risk group of patients, probably due to its greater effects for reducing portal pressure. | José Ignacio Fortea ángela Puente Patricia Ruiz Iranzu Ezcurra Javier Vaquero Antonio Cuadrado María Teresa Arias-Loste Joaquín Cabezas Susana Llerena Paula Iruzubieta Carlos Rodríguez-Lope Patricia Huelin Fernando Casafont Emilio Fábrega Javier Crespo | 2018 | World Journal of Clinical Cases2018，6，13： | 6 |
| 4 | Clinical significance of donor-specific human leukocyte antigen antibodies in liver transplantation显示文摘Antibody-mediated rejection(AMR) caused by donorspecific anti-human leukocyte antigen antibodies(DSA) is widely accepted to be a risk factor for decreased graft survival after kidney transplantation. This entity also plays a pathogenic role in other solid organ transplants as it appears to be an increasingly common cause of heart graft dysfunction and an emerging issue in lung transplantation. In contrast, the liver appears relatively resistant to DSA-mediated injury. This 'immune-tolerance' liver property has been sustained by a low rate of liver graft loss in patients with preformed DSA and by the intrinsic liver characteristics that favor the absorption and elimination of DSA; however, alloantibody-mediated adverse consequences are increasingly being recognized, and several cases of acute AMR after ABO-compatible liver transplant(LT) have been reported. Furthermore, the availability of new solid-phase assays, allowing the detection of low titers of DSA and the refinement of objective diagnostic criteria for AMR in solid organ transplants and particularly in LT, have improved the recognition and management of this entity. A cost-effective strategy of DSA monitoring, avoidance of class Ⅱ human leukocyte antigen mismatching, judicious immunosuppression attached to a higher level of clinical suspicion of AMR, particularly in cases unresponsive to conventional antirejection therapy, can allow a rational approach to this threat. | Antonio Cuadrado David San Segundo Marcos López-Hoyos Javier Crespo Emilio Fábrega | 2015 | World Journal of Gastroenterology2015，21，39： | 5 |

| 6 | Long-term survival after liver transplantation for alcoholic liver disease显示文摘Currently,alcoholic cirrhosis is the second leading indication for liver transplantation in the United States and Europe.The quality of life and survival after a liver transplantation(LT)in patients with alcoholic liver disease(ALD)are similar to those in patients with other cirrhosis etiologies.The alcoholic relapse rate after a LT varies from 10%-50%,and these relapse patients are the ones who present a reduced long-term survival,mainly due to cardiovascular diseases and the onset of de novo neoplasms,including lung and upper aerodigestive tract.Nearly 40%of ALD recipients resume smoking and resume it early post-LT.Therefore,our pre-and post-LT follow-up efforts regarding ALD should be focused not only on alcoholic relapse but also on treating and avoiding other modifiable risk factors such as tobacco.The psychiatric and psychosocial pre-LT evaluation and the post-LT follow-up with physicians,psychiatrists and addiction specialists are important for reversing these problems because these professionals help to identify patients at risk for relapse as well as those patients who have relapsed,thus enabling responsive actions. | Paula Iruzubieta Javier Crespo Emilio Fábrega | 2013 | World Journal of Gastroenterology2013，19，48： | 4 |

| 11 | The role of the PI3K/AKT/mTOR pathway in brain tumor metastasis显示文摘The PI3K/AKT/mTOR(PAM)pathway is involved in a variety of cellular functions and often contributes to oncogenesis and cancer progression.It has been recognized that this pathway is frequently activated in the most common central nervous system cancers of adults and children,malignant gliomas and medulloblastomas(MB).In these tumors,the PAM network controls key functions necessary for cell invasion and metastasis,such as cell motility.This review summarizes the current knowledge about the role of PAM signaling in cell invasion and metastasis in gliomas and MB.Current approaches to inhibit cell invasion and metastasis by targeting the PAM pathway will also be discussed. | Silvia Crespo Marcus Kind Alexandre Arcaro | 2016 | Journal of Cancer Metastasis and Treatment2016，2，1： | 2 |

| 14 | Clinical significance of'anti-HBc alone'in human immunodeficiency virus-positive patients显示文摘AIM:To determine the prevalence and clinical relevance of isolated antibodies to hepatitis B core antigen as the only marker of infection('anti-HBc alone')among human immunodeficiency virus(HIV) type-1 infected patients.Occult hepatitis B infection frequency was also evaluated. METHODS:Three hundred and forty eight histories from 2388 HIV-positive patients were randomly reviewed.Patients with serological markers of hepatitis B virus(HBV)infection were classified into three groups:past hepatitis,'anti-HBc alone'and chronic hepatitis.Determination of DNA from HBV,and RNA and genotype from hepatitis C virus(HCV)were performed on'anti-HBc alone'patients. RESULTS:One hundred and eighty seven(53.7%) HIV-positive patients had markers of HBV infection: 118 past infection(63.1%),14 chronic hepatitis (7.5%)and 55'anti-HBc alone'(29.4%).Younger age[2.3-fold higher per every 10 years younger;95% confidence intervals(CI)1.33-4.00]and antibodies to HCV infection[odds ratio(OR)2.87;95%CI 1.10-7.48]were factors independently associated with the'anti-HBc alone'pattern.No differences in liver disease frequency were detected between both groups. Serum levels of anti-HBs were not associated with HCV infection(nor viral replication or HCV genotype),or with HIV replication or CD4 level.No'anti-HBc alone' patient tested positive for HBV DNA. CONCLUSION:'Anti-HBc alone'prevalence in HIVpositive patients was similar to previously reported data and was associated with a younger age and with antibodies to HCV infection.In clinical practice,HBV DNA determination should be performed only in those patients with clinical or analytical signs of liver injury. | M~aTeresa Pérez-Rodríguez Bernardo Sopea Manuel Crespo Alberto Rivera Teresa González del Blanco Antonio Ocampo César Martínez-Vázquez | 2009 | World Journal of Gastroenterology2009，15，10： | 2 |
| 15 | DuaISPHysics:A numerical tool to simulate real breakwaters显示文摘The open-source code DualSPHysics is used in this work to compute the wave run-up in an existing dike in the Chinese coast using realistic dimensions, bathymetry and wave conditions. The GPU computing power of the DualSPHysics allows simulating real-engineering problems that involve complex geometries with a high resolution in a reasonable computational time. The code is first validated by comparing the numerical free-surface elevation, the wave orbital velocities and the time series of the run-up with physical data in a wave flume. Those experiments include a smooth dike and an armored dike with two layers of cubic blocks. After validation,the code is applied to a real case to obtain the wave run-up under different incident wave conditions. In order to simulate the real open sea, the spurious reflections from the wavemaker are removed by using an active wave absorption technique. | 张峰 Alejandro Crespo Corrado Altomare José Domínguez Andrea Marzeddu 商少平 Moncho Gómez-Gesteira | 2018 | Journal of Hydrodynamics2018，30，1： | 2 |
| 16 | The impact of having an oxygen-rich microporous surface in carbon electrodes for high-power aqueous supercapacitors显示文摘The growth of electrical transportation is crucially important to mitigate rising climate change concerns regarding materials supply.Supercapacitors are high-power devices,particularly suitable for public transportation since they can easily store breaking energy due to their high-rate charging ability.Additionally,they can function with two carbon electrodes,which is an advantage due to the abundance of carbon in biomass and other waste materials(i.e.,plastic waste).Newly developed supercapacitive nanocarbons display extremely narrow micropores(<0.8 nm),as it increases drastically the capacitance in aqueous electrolytes.Here,we present a strategy to produce low-cost flexible microporous electrodes with extremely high power density(>100 kW kg^(-1)),using fourty times less activating agent than traditionnal chemically activated carbons.We also demonstrate that the affinity between the carbon and the electrolyte is of paramount importance to maintain rapid ionic diffusion in narrow micropores.Finally,this facile synthesis method shows that low-cost and bio-based free-standing electrode materials with reliable supercapacitive performances can be used in electrochemistry. | Servann Herou Maria Crespo Ribadeneyr Philipp Schlee Hui Luo Liviu Cristian Tanase Christine Roβberg Magdalena Titirici | 2021 | Journal of Energy Chemistry2021，30，2： | 2 |
