| 1 | Mitochondrial protection by low doses of insulin-like growth factor-Ⅰin experimental cirrhosis显示文摘AIM: To characterize the mitochondrial dysfunction in experimental cirrhosis and to study whether insulin-like growth factor-Ⅰ(IGF-Ⅰ) therapy (4 wk) is able to induce beneficial effects on damaged mitochondria leading to cellular protection. METHODS: Wistar rats were divided into three groups: Control group, untreated cirrhotic rats and cirrhotic rats treated with IGF-Ⅰtreatment (2 μg/100 g bw/d). Mitochondrial function was analyzed by flow cytometry in isolated hepatic mitochondria, caspase 3 activation was assessed by Western blot and apoptosis by TUNEL in the three experimental groups. RESULTS: Untreated cirrhotic rats showed a mitochon- drial dysfunction characterized by a significant reduction of mitochondrial membrane potential (in status 4 and 3); an increase of intramitochondrial reactive oxigen species (ROS) generation and a significant reduction of ATPase activity. IGF-Ⅰtherapy normalized mitochondrial func-tion by increasing the membrane potential and ATPase activity and reducing the intramitochondrial free radical production. Activity of the electron transport complexes Ⅰand Ⅲ was increased in both cirrhotic groups. In addition, untreated cirrhotic rats showed an increase of caspase 3 activation and apoptosis. IGF-Ⅰtherapy reduced the expression of the active peptide of caspase 3 and resulted in reduced apoptosis. | Raquel Pérez María García-Fernández Matías Díaz-Sánchez Juan E Puche Gloria Delgado Marian Conchillo Jordi Muntané Inma Castilla-Cortázar | 2008 | World Journal of Gastroenterology2008，14，17： | 11 |
| 2 | Endoscopic submucosal dissection training with pig models in a Western country显示文摘AIM:To test a strategy for endoscopic submucosal dissection(ESD) training in animal models designed to overcome the initial learning curve.METHODS:ESD was attempted in ex vivo and in vivo pig models.Thirty ESD procedures were attempted in the esophagus(n=9) or the stomach(n=21).The ex vivo model was used until initial competence was achieved.In the in vivo model,several ESD procedures were performed in up to 3 sessions.The following variables were analyzed:specimen size,complete and en bloc resection rate,time for circumferential incision,time for submucosal dissection,total ESD duration,and complications.RESULTS:Complete resection was achieved in 28 cases(en bloc 27);2 could not be completed(one perforation,one technical diff iculty).The mean ± SD time for circumferential incision was 36.2±16.8 min(range:8-87 min),and the mean±SD time for submucosal dissection was 45.1±35.7 min(range:9-196 min).The mean±SD size of the resected specimens was 45.2±17.8 mm.The mean±SD total resection time was signif icantly increased for the gastric cases performed in the f irst half of the study(n=13) than in the second half(n=8)(98.9±62.4 min vs 61.7±17.6 min,P=0.04),although the specimen size did not differ.CONCLUSION:Training in animal models could help endoscopists overcome the learning curve before starting ESD in humans. | Adolfo Parra-Blanco María Rosa Arnau David Nicolás-Pérez Antonio Z Gimeno-García Nicolás González Juan A Díaz-Acosta Alejandro Jiménez Enrique Quintero | 2010 | World Journal of Gastroenterology2010，16，23： | 9 |
| 3 | Soluble ST2:A new and promising activity marker in ulcerative colitis显示文摘AIM:To correlate circulating soluble ST2(sST2) levels with the severity of ulcerative colitis(UC) and serum levels of pro-inflammatory cytokines,and to demonstrate the predictive power of sST2 levels for differentiation between active and inactive UC.METHODS:We recruited 153 patients:82 with UC,26 with Crohn's disease(CD) and 43 disease controls [non-inflammatory bowel disease(IBD)].Subjects were excluded if they had diagnosis of asthma,autoimmune diseases or hypertension.The serum levels of sST2 and pro-inflammatory cytokines [pg/mL;median(25th-75th)] as well as clinical features,endoscopic and histological features,were subjected to analyses.The sST2 performance for discrimination between active and inactive UC,non-IBD and healthy controls(HC) was determined with regard to sensitivity and specificity,and Spearman's rank correlation coefficient(r).To validate the method,the area under the curve(AUC) of receiver-operator characteristic(ROC) was determined(AUC,95% CI) and the total ST2 content of the colonic mucosa in UC patients was correlated with circulating levels of sST2.RESULTS:The serum sST2 value was significantly higher in patients with active [235.80(90.65-367.90) pg/mL] rather than inactive UC [33.19(20.04-65.32) pg/mL],based on clinical,endoscopic and histopathological characteristics,as well as compared with non-IBD and HC(P < 0.001).The median level of sST2 in CD patients was 54.17(35.02-122.0) pg/mL,significantly higher than that of the HC group only(P < 0.01).The cutoff was set at 74.87 pg/mL to compare active with inactive UC in a multicenter cohort of patients.Values of sensitivity,specificity,and ability to correctly classify UC,according to activity,were 83.33%,83.33% and 83.33%,respectively.The AUC of the ROC curve to assess the ability of this molecule to discriminate between active vs inactive UC was 0.92(0.86-0.97,P < 0.0001).The serum levels of sST2 in patients with UC significantly correlated with endoscopic and histo-pathological scores(r = 0.76 and r = 0.67,P < 0.0001,respectively),and with the pro-inflammatory cytokine,tumor necrosis factor-α(r = 0.69 and r = 0.61,respectively,P < 0.0001).Interestingly,we found a direct correlation between total intestinal ST2 content and serum levels of sST2,adjusted to endoscopic activity score in patients with mild(r = 0.44,P = 0.004),moderate(r = 0.59,P = 0.002) and severe disease(r = 0.82,P = 0.002).Only patients with inactive UC showed no significant correlation(r = 0.45,P = 0.267).CONCLUSION:sST2 levels correlated with disease severity and inflammatory cytokines,are able to differentiate active from inactive UC and might have a role as a biomarker. | David Díaz-Jiménez Lucía E Núez Caroll J Beltrán Enzo Candia Cristóbal Suazo Manuel varez-Lobos María-Julieta González Marcela A Hermoso Rodrigo Quera | 2011 | World Journal of Gastroenterology2011，17，17： | 8 |
| 4 | Glutathione depleting drugs, antioxidants and intestinal calcium absorption显示文摘Glutathione(GSH) is a tripeptide that constitutes one of the main intracellular reducing compounds. The normal content of GSH in the intestine is essential to optimize the intestinal Ca2+ absorption. The use of GSH depleting drugs such as DL-buthionine-S,R-sulfoximine, menadione or vitamin K3, sodium deoxycholate or diets enriched in fructose, which induce several features of the metabolic syndrome, produce inhibition of the intestinal Ca2+ absorption. The GSH depleting drugs switch the redox state towards an oxidant condition provoking oxidative/nitrosative stress and inflammation, which lead to apoptosis and/or autophagy of the enterocytes. Either the transcellular Ca2+ transport or the paracellular Ca2+ route are altered by GSH depleting drugs. The gene and/or protein expression of transporters involved in the transcellular Ca2+ pathway are decreased. The flavonoids quercetin and naringin highly abrogate the inhibition of intestinal Ca2+ absorption, not only by restoration of the GSH levels in the intestine but also by their anti-apoptotic properties. Ursodeoxycholic acid, melatonin and glutamine also block the inhibition of Ca2+ transport caused by GSH depleting drugs. The use of any of these antioxidants to ameliorate the intestinal Ca2+ absorption under oxidant conditions associated with different pathologies in humans requires more investigation with regards to the safety, pharmacokinetics and pharmacodynamics of them. | Luciana Moine María Rivoira Gabriela Díaz de Barboza Adriana Pérez Nori Tolosa de Talamoni | 2018 | World Journal of Gastroenterology2018，24，44： | 5 |
| 5 | Management of oligometastatic non-small cell lung cancer patients:Current controversies and future directions显示文摘Oligometastatic non-small cell lung cancer(NSCLC)describes an intermediate stage of NSCLC between localized and widely-disseminated disease.This stage of NSCLC is characterized by a limited number of metastases and a more indolent tumor biology.Currently,the management of oligometastatic NSCLC involves radical treatment(radiotherapy or surgery)that targets the metastatic lesions and the primary tumor to achieve disease control.This approach offers the potential to achieve prolonged survival in patients who,in the past,would have only received palliative measures.The optimal therapeutic strategies for the different scenarios of oligometastatic disease(intracranial vs extracranial disease,synchronous vs metachronous)remain undefined.Given the lack of head-to-head studies comparing radiotherapy to surgery in these patients,the decision to apply surgery or radiotherapy(with or without systemic treatment)must be based on prognostic factors that allow us to classify patients.This classification will allow us to select the most appropriate therapeutic strategy on an individualized basis.In the future,the molecular or microRNA profiles will likely improve the treatment selection process.The objective of the present article is to review the most relevant scientific evidence on the management of patients with oligometastatic NSCLC,focusing on the role of radiotherapy and surgery.We also discuss areas of controversy and future directions. | Felipe Counago Javier Luna Luis Leonardo Guerrero Blanca Vaquero María Cecilia Guillén-Sacoto Teresa González-Merino Begona Taboada Verónica Díaz Belén Rubio-Viqueira Ana Aurora Díaz-Gavela Francisco JoséMarcos Elia del Cerro | 2019 | World Journal of Clinical Oncology2019，10，10： | 5 |
| 6 | Tumor microenvironment involvement in colorectal cancer progression via Wnt/β-catenin pathway:Providing understanding of the complex mechanisms of chemoresistance显示文摘Colorectal cancer(CRC)continues to be one of the main causes of death from cancer because patients progress unfavorably due to resistance to current therapies.Dysregulation of the Wnt/β-catenin pathway plays a fundamental role in the genesis and progression of several types of cancer,including CRC.In many subtypes of CRC,hyperactivation of theβ-catenin pathway is associated with mutations of the adenomatous polyposis coli gene.However,it can also be associated with other causes.In recent years,studies of the tumor microenvironment(TME)have demonstrated its importance in the development and progression of CRC.In this tumor nest,several cell types,structures,and biomolecules interact with neoplastic cells to pave the way for the spread of the disease.Cross-communications between tumor cells and the TME are then established primarily through paracrine factors,which trigger the activation of numerous signaling pathways.Crucial advances in the field of oncology have been made in the last decade.This Minireview aims to actualize what is known about the central role of the Wnt/β-catenin pathway in CRC chemoresistance and aggressiveness,focusing on crosscommunication between CRC cells and the TME.Through this analysis,our main objective was to increase the understanding of this complex disease considering a more global context.Since many treatments for advanced CRC fail due to mechanisms involving chemoresistance,the data here exposed and analyzed are of great interest for the development of novel and effective therapies. | María Belén Novoa Díaz María Julia Martín Claudia Gentili | 2022 | World Journal of Gastroenterology2022，28，26： | 3 |
| 7 | Effect of femtosecond laser-assisted lens surgery on the optic nerve head and the macula显示文摘AIM: To evaluate the effect of femtosecond laser-assisted lens surgery(FLALS;cataract surgery or refractive lens exchange) on the structure of the optic nerve head and the macula.METHODS: This prospective longitudinal study included healthy eyes undergoing FLALS. Eyes with glaucoma or any other ocular disease that could alter optical coherence tomography results were excluded. Retinal nerve fiber layer(RNFL), Bruch’s membrane opening-minimum rim width(BMO-MRW) and macular thickness(MT) were measured preoperatively, 1 and 6 mo after surgery using spectral-domain optical coherence tomography(SD-OCT). Changes between preoperative and postoperative values were evaluated.RESULTS: A total of 87 eyes of 46 patients were included in this study. Preoperative RNFL, BMO-MRW and MT in microns(μm) were 100.77±10.39, 330.31±49.99 and 276.30±33.39, respectively. Postoperative RNFL, BMO-MRW and MT were 104.74±11.55, 348.32±54.05 and 279.83±22.65 1 mo after surgery and 102.93±11.17, 343.11±53.4 and 278.90±22.19 6 mo after surgery, respectively;which equals an increase of 3.93%, 5.45% and 1.27%,respectively, 1 mo after surgery, and 2.14%, 3.87% and 0.94% 6 mo after surgery. The differences between the preoperative and the postoperative RNFL and BMO-MRW values were statistically significant(P<0.001). Regarding MT values, there were not statistically significant differences(P=0.26).CONCLUSION: Our study suggests that FLALS does not have a negative impact on the structural status of the optic nerve head in healthy eyes, assessed by SD-OCT. There is a slight increase in the values of RNFL, BMO-MRW and MT 1 mo and 6 mo after surgery. | Josefina Renones de Abajo Beatriz Estévez Jorge Jesús María González Martín Humberto Carreras Díaz Juan Francisco Loro Ferrer Alfonso Antón López | 2019 | International Journal of Ophthalmology(English edition)2019，12，6： | 2 |
| 8 | Coronary physiology assessment in the catheterization laboratory显示文摘Physicians cannot rely solely on the angiographic appearance of epicardial coronary artery stenosis when evaluating patients with myocardial ischemia. Instead, sound knowledge of coronary vascular physiology and of the methods currently available for its characterization can improve the diagnostic and prognostic accuracy of invasive assessment of the coronary circulation, and help improve clinical decision-making. In this article we summarize the current methods available for a thorough assessment of coronary physiology. | Felipe Díez-delhoyo Enrique Gutiérrez-Ibanes Gerard Loughlin Ricardo Sanz-Ruiz María Eugenia Vázquez-álvarez Fernando Sarnago-Cebada Rocío Angulo-Llanos Ana Casado-Plasencia Jaime Elízaga Francisco Fernández Avilés Diáz | 2015 | World Journal of Cardiology2015，7，9： | 2 |

| 10 | ddRAD sequencing-based genotyping for population structure analysis in cultivated tomato provides new insights into the genomic diversity of Mediterranean‘da serbo’type long shelf-life germplasm显示文摘Double digest restriction-site associated sequencing(ddRAD-seq)is a flexible and cost-effective strategy for providing in-depth insights into the genetic architecture of germplasm collections.Using this methodology,we investigated the genomic diversity of a panel of 288 diverse tomato(Solanum lycopersicum L.)accessions enriched in‘da serbo’(called‘de penjar’in Spain)long shelf life(LSL)materials(152 accessions)mostly originating from Italy and Spain.The rest of the materials originate from different countries and include landraces for fresh consumption,elite cultivars,heirlooms,and breeding lines.Apart from their LSL trait,‘da serbo’landraces are of remarkable interest for their resilience.We identified 32,799 high-quality SNPs,which were used for model ancestry population structure and non-parametric hierarchical clustering.Six genetic subgroups were revealed,clearly separating most‘da serbo’landraces,but also the Spanish germplasm,suggesting a subdivision of the population based on type and geographical provenance.Linkage disequilibrium(LD)in the collection decayed very rapidly within<5 kb.We then investigated SNPs showing contrasted minor frequency allele(MAF)in‘da serbo’materials,resulting in the identification of high frequencies in this germplasm of several mutations in genes related to stress tolerance and fruit maturation such as CTR1 and JAR1.Finally,a mini-core collection of 58 accessions encompassing most of the diversity was selected for further exploitation of key traits.Our findings suggest the presence of a genetic footprint of the‘da serbo’germplasm selected in the Mediterranean basin.Moreover,we provide novel insights on LSL‘da serbo’germplasm as a promising source of alleles for tolerance to stresses. | Salvatore Esposito Teodoro Cardi Gabriele Campanelli Sara Sestili María JoséDíez Salvador Soler Jaime Prohens Pasquale Tripodi | 2020 | Horticulture Research2020，7，1： | 2 |

| 15 | Exploiting the diversity of tomato:the development of a phenotypically and genetically detailed germplasm collection显示文摘A collection of 163 accessions,including Solanum pimpinellifolium,Solanum lycopersicum var.cerasiforme and Solanum lycopersicum var.lycopersicum,was selected to represent the genetic and morphological variability of tomato at its centers of origin and domestication:Andean regions of Peru and Ecuador and Mesoamerica.The collection is enriched with S.lycopersicum var.cerasiforme from the Amazonian region that has not been analyzed previously nor used extensively.The collection has been morphologically characterized showing diversity for fruit,flower and vegetative traits.Their genomes were sequenced in the Varitome project and are publicly available(solgenomics.net/projects/varitome).The identified SNPs have been annotated with respect to their impact and a total number of 37,974 out of 19,364,146 SNPs have been described as high impact by the SnpEeff analysis.GWAS has shown associations for different traits,demonstrating the potential of this collection for this kind of analysis.We have not only identified known QTLs and genes,but also new regions associated with traits such as fruit color,number of flowers per inflorescence or inflorescence architecture.To speed up and facilitate the use of this information,F2 populations were constructed by crossing the whole collection with three different parents.This F2 collection is useful for testing SNPs identified by GWAs,selection sweeps or any other candidate gene.All data is available on Solanaceae Genomics Network and the accession and F2 seeds are freely available at COMAV and at TGRC genebanks.All these resources together make this collection a good candidate for genetic studies. | Estefanía Mata-Nicolás Javier Montero-Pau Esther Gimeno-Paez Víctor Garcia-Carpintero Peio Ziarsolo Naama Menda Lukas A.Mueller JoséBlanca Joaquín Cañizares Esther van der Knaap María JoséDíez | 2020 | Horticulture Research2020，7，1： | 2 |
