| 1 | 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 |

| 4 | Efficacy of neoadjuvant therapy and surgical rescue for locally advanced hepatoblastomas:10 year single-center experience and literature review显示文摘AIM:To report our experience with long-term outcomes after multimodal management therapy.METHODS:An observational retrospective study was performed containing seven patients with hepatoblastoma(Hbl)treated in our institution,a tertiary referral center,from 2003 to 2011.Demographic,preoperative,surgical,and outcome variables were collected.A survival analysis and a review of the current literature related to combination neoadjuvant chemotherapy and surgical resection on Hbl were performed.RESULTS:The median age at surgery was 14.4 mo,with a male to female ratio of 4:3.Pretext staging at diagnosis was as follows:stageⅠ,4 cases;stageⅡ,2 patients;and stageⅢ,1 case.Mean pretreatment tumor volume was 735 cm3.Five out of seven patients received neoadjuvant chemotherapy according to SIOPEL-3 or SIOPEL-6 protocols.Tumor volume and alphafetoprotein levels significantly dropped after neoadjuvant therapy.Surgical procedures performed included hemihepatectomies,segmentectomies and atypical resection.All patients received chemotherapy after surgery.Median postoperative hospital stay was 8 d.All patients were alive and disease-free after a median follow-up period of 23 mo.With regards to the literature review,seventeen articles were found that were related to our search.CONCLUSION:Our series shows how multimodal management of Hbl,exhaustive control and a meticulous surgical approach leads to almost 100%complete resection with optimal postoperative results. | Dolores Ayllon Teran Oscar Gómez Beltran Rubén Ciria Bru Elena Mateos González María José Pea Rosa Antonio Luque Molina Pedro López Cillero Javier Briceo Delgado | 2014 | World Journal of Gastroenterology2014，20，29： | 12 |
| 5 | Platelet-rich plasma,an adjuvant biological therapy to assist peripheral nerve repair显示文摘Therapies such as direct tension-free microsurgical repair or transplantation of a nerve autograft,are nowadays used to treat traumatic peripheral nerve injuries(PNI),focused on the enhancement of the intrinsic regenerative potential of injured axons.However,these therapies fail to recreate the suitable cellular and molecular microenvironment of peripheral nerve repair and in some cases,the functional recovery of nerve injuries is incomplete.Thus,new biomedical engineering strategies based on tissue engineering approaches through molecular intervention and scaffolding offer promising outcomes on the field.In this sense,evidence is accumulating in both,preclinical and clinical settings,indicating that platelet-rich plasma products,and fibrin scaffold obtained from this technology,hold an important therapeutic potential as a neuroprotective,neurogenic and neuroinflammatory therapeutic modulator system,as well as enhancing the sensory and motor functional nerve muscle unit recovery. | Mikel Sánchez Ane Garate Diego Delgado Sabino Padilla | 2017 | Neural Regeneration Research2017，12，1： | 12 |
| 6 | 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 |
| 7 | Helicobacter pylori and skin autoimmune diseases显示文摘Autoimmune skin diseases are characterized by dysregulation of the immune system resulting in a loss of tolerance to skin self-antigen(s). The prolonged interaction between the bacterium and host immune mechanisms makes Helicobacter pylori(H. pylori) a plausible infectious agent for triggering autoimmunity. Epidemiological and experimental data now point to a strong relation of H. pylori infection on the development of many extragastric diseases, including several allergic and autoimmune diseases. H. pylori antigens activate cross-reactive T cells and induce autoantibodies production. Microbial heat shock proteins(HSP) play an important role of in the pathogenesis of autoimmune diseases because of the high level of sequence homology with human HSP. Eradication of H. pylori infection has been shown to be effective in some patients with chronic autoimmune urticaria, psoriasis, alopecia areata and Schoenlein-Henoch purpura. There is conflicting and controversial data regarding the association of H. pylori infection with Beh et's disease, scleroderma and autoimmune bullous diseases. No data are available evaluating the association of H. pylori infection with other skin autoimmune diseases, such as vitiligo, cutaneous lupus erythematosus and dermatomyositis. The epidemiological and experimental evidence for a possible role of H. pylori infection in skin autoimmune diseases are the subject of this review. | Eli Magen Jorge-Shmuel Delgado | 2014 | World Journal of Gastroenterology2014，20，6： | 10 |
| 8 | Differences in standing balance between patients with diplegic and hemiplegic cerebral palsy显示文摘Maintaining standing postural balance is important for walking and handling abilities in patients with cerebral palsy.This study included 23 patients with cerebral palsy(seven with spastic diplegia and16 with spastic hemiplegia),aged from 7 to 16 years of age.Standing posture balance measurements were performed using an AMTI model OR6-7 force platform with the eyes open and closed.Patients with diplegic cerebral palsy exhibited greater center of pressure displacement areas with the eyes open and greater center of pressure sway in the medial-lateral direction with the eyes open and closed compared with hemiplegic patients.Thus,diplegic patients exhibited weaker postural balance control ability and less standing stability compared with hemiplegic cerebral palsy patients. | Valeska Gatica Rojas Guillermo Méndez Rebolledo Eduardo Guzman Muoz Natalia Ibarra Cortés Caterine Berrios Gaete Carlos Manterola Delgado | 2013 | Neural Regeneration Research2013，8，26： | 6 |

| 10 | Propofol vs traditional sedatives for sedation in endoscopy:A systematic review and meta-analysis显示文摘BACKGROUND Propofol is commonly used for sedation during endoscopic procedures.Data suggests its superiority to traditional sedatives used in endoscopy including benzodiazepines and opioids with more rapid onset of action and improved postprocedure recovery times for patients.However,Propofol requires administration by trained healthcare providers,has a narrow therapeutic index,lacks an antidote and increases risks of cardio-pulmonary complications.AIM To compare,through a systematic review of the literature and meta-analysis,sedation with propofol to traditional sedatives with or without propofol during endoscopic procedures.METHODS A literature search was performed using MEDLINE,Scopus,EMBASE,the Cochrane Library,Scopus,LILACS,BVS,Cochrane Central Register of Controlled Trials,and The Cumulative Index to Nursing and Allied Health Literature databases.The last search in the literature was performed on March,2019 with no restriction regarding the idiom or the year of publication.Only randomized clinical trials with full texts published were included.We divided sedation therapies to the following groups:(1)Propofol versus benzodiazepines and/or opiate sedatives;(2)Propofol versus Propofol with benzodiazepine and/or opioids;and(3)Propofol with adjunctive benzodiazepine and opioid versus benzodiazepine and opioid.The following outcomes were addressed:Adverse events,patient satisfaction with type of sedation,endoscopists satisfaction with sedation administered,dose of propofol administered and time to recovery post procedure.Meta-analysis was performed using RevMan5 software version 5.39.RESULTS A total of 23 clinical trials were included(n=3854)from the initial search of 6410 articles.For Group I(Propofol vs benzodiazepine and/or opioids):The incidence of bradycardia was not statistically different between both sedation arms(RD:-0.01,95%CI:-0.03–+0.01,I2:22%).In 10 studies,the incidence of hypotension was not statistically difference between sedation arms(RD:0.01,95%CI:-0.02–+0.04,I2:0%).Oxygen desaturation was higher in the propofol group but not statistically different between groups(RD:-0.03,95%CI:-0.06–+0.00,I2:25%).Patients were more satisfied with their sedation in the benzodiazepine+opioid group compared to those with monotherapy propofol sedation(MD:+0.89,95%CI:+0.62–+1.17,I2:39%).The recovery time after the procedure showed high heterogeneity even after outlier withdrawal,there was no statistical difference between both arms(MD:-15.15,95%CI:-31.85–+1.56,I2:99%).For Group II(Propofol vs propofol with benzodiazepine and/or opioids):Bradycardia had a tendency to occur in the Propofol group with benzodiazepine and/or opioidassociated(RD:-0.08,95%CI:-0.13–-0.02,I2:59%).There was no statistical difference in the incidence of bradycardia(RD:-0.00,95%CI:-0.08–+0.08,I2:85%),desaturation(RD:-0.00,95%CI:-0.03–+0.02,I2:44%)or recovery time(MD:-2.04,95%CI:-6.96–+2.88,I2:97%)between sedation arms.The total dose of propofol was higher in the propofol group with benzodiazepine and/or opiates but with high heterogeneity.(MD:70.36,95%CI:+53.11–+87.60,I2:61%).For Group III(Propofol with benzodiazepine and opioid vs benzodiazepine and opioid):Bradycardia and hypotension was not statistically significant between groups(RD:-0.00,95%CI:-0.002–+0.02,I2:3%;RD:0.04,95%CI:-0.05–+0.13,I2:77%).Desaturation was evaluated in two articles and was higher in the propofol+benzodiazepine+opioid group,but with high heterogeneity(RD:0.15,95%CI:0.08–+0.22,I2:95%).CONCLUSION This meta-analysis suggests that the use of propofol alone or in combination with traditional adjunctive sedatives is safe and does not result in an increase in negative outcomes in patients undergoing endoscopic procedures. | Aureo Augusto de Almeida Delgado Diogo Turiani Hourneaux de Moura Igor Braga Ribeiro Ahmad Najdat Bazarbashi Marcos Eduardo Lera dos Santos Wanderley Marques Bernardo Eduardo Guimaraes Hourneaux de Moura | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，12： | 6 |
| 11 | Single-lung transplantation in emphysema:Retrospective study analyzing survival and waiting list mortality显示文摘AIM: To performed remains a subject of debate and is the principal aim of the study. METHODS: This retrospective analysis included 73 patients with emphysema(2000-2012). The outcomes of patients undergoing single-lung transplantation(SL)(n = 40) or double-lung transplant(DL)(n = 33) were compared in a Cox multivariate analysis to study the impact of the technique, postoperative complications and acute and chronic rejection on survival rates. Patients were selected for inclusion in the waiting list according to the International Society of Heart Lung Transplantation criteria. Pre and postoperative rehabilitation and prophylaxis, surgical technique and immunosuppressive treatment were similar in every patients. Lung transplantation waiting list information on a national level and retrospective data on emphysema patient survival transplanted in Spain during the study period, was obtained from the lung transplantation registry managed by the National Transplant Organization(ONT). RESULTS: Both groups were comparable in terms of gender and clinical characteristics. We found significant differences in the mean age between the groups, the DL patients being younger as expected from the inclusion criteria. Perioperative complications occurred in 27.6% SL vs 54% DL(P = 0.032). Excluding perioperative mortality, median survival was 65.3 mo for SL and 59.4 mo for DL(P = 0.96). Bronchiolitis obliterans and overall 5-year survival were similar in both groups. Bacterialrespiratory infection, cytomegalovirus and fungal infection rates were higher but not significant in SL. No differences were found between type of transplant and survival(P = 0.48). To support our results, national data on all patients with emphysema in waiting list were obtained(n = 1001). Mortality on the waiting list was 2.4% for SL vs 6.2% for DL. There was no difference in 5 year survival between 235 SL and 430 DL patients transplanted(P = 0.875).CONCLUSION: Our results suggest that SL transplantation in emphysema produce similar survival than DL with less postoperative complication and significant lower mortality in waiting list. | José M Borro María Delgado Elisabeth Coll Salvador Pita | 2016 | World Journal of Transplantation2016，6，2： | 6 |
| 12 | Helicobacter pylori CagA protein polymorphisms and their lack of association with pathogenesis显示文摘AIM: To investigate Helicobacter pylori (H. pylori) CagA diversity and to evaluate the association between protein polymorphisms and the occurrence of gastric pathologies. METHODS: One hundred and twenty-two clinical isolates of H. pylori cultured from gastric biopsies obtained from Colombian patients with dyspepsia were included as study material. DNA extracted from isolates was used to determine cagA status, amplifying the C-terminal cagA gene region by polymerase chain reaction. One hundred and six strains with a single amplicon were sequenced and results were used to characterize the 3' variable region of the cagA gene. To establish the number and type of tyrosine phosphorylation motifs Glutamine acid-Proline-Isoleucine-Tyrosine-Alanine (EPI-YA) bioinformatic analysis using Amino Acid Sequence Analyzer-Amino Acid Sequence Analyzer software was conducted. Analysis of the association between the number of EPIYA motifs and the gastric pathology was performed using χ2 test and analysis of the presence of EPIYA-C motifs in relation to the pathology was made by logistic regression odds ratios. Comparisons among EPIYA types found and those reported in GenBank were performed using a proportion test in Statistix Analytical Software version 8.0. RESULTS: After amplification of the 3' of the cagA gene, 106 from 122 isolates presented a single amplicon and 16 showed multiple amplicons. As expected, diversity in the size of the cagA unique fragments among isolates was observed. The 106 strains that presented a single amplicon after 3' cagA amplification came from patients with gastritis (19 patients), atrophic gastritis (21), intestinal metaplasia (26), duodenal ulcer (22) and gastric cancer. DNA sequence analysis showed that the differences in size of 3' cagA unique fragments was attributable to the number of EPIYA motifs: 1.9% had two EPIYA motifs, 62.3% had three, 33.0% had four and 2.8% had five motifs. The majority of tested clinical strains (62.3%) were found to harbor the ABC combination of EPIYA motifs and a significant statistical difference was observed between the frequencies of ABCC tyrosine phosphorylation motifs and Western strains sequences deposited in GenBank. CONCLUSION: The present report describes a lack of association between H. pylori CagA-protein polymorphisms and pathogenesis. ABCC high frequency variations compared with Western-strains sequences deposited in GenBank require more investigation. | Nicole Acosta Andrés Quiroga Pilar Delgado María Mercedes Bravo Carlos Jaramillo | 2010 | World Journal of Gastroenterology2010，16，31： | 5 |

| 14 | Adjuvant therapy sparing in rectal cancer achieving complete response after chemoradiation显示文摘AIM:To evaluate the long-term results of conventional chemoradiotherapy and laparoscopic mesorectal excision in rectal adenocarcinoma patients without adjuvant therapy.METHODS:Patients with biopsy-proven adenocarcinoma of the rectum staged cT3-T4 by endoscopic ultrasound or magnetic resonance imaging received neoadjuvant continuous infusion of 5-fluorouracil for five weeks and concomitant radiotherapy.Laparoscopic surgery was planned after 5-8 wk.Patients diagnosed with ypT0N0 stage cancer were not treated with adjuvant therapy according to the protocol.Patients with ypT1-2N0 or ypT3-4 or N+were offered 5-fluorouracil-based adjuvant treatment on an individual basis.An external cohort was used as a reference for the findings.RESULTS:One hundred and seventy six patients were treated with induction chemoradiotherapy and 170underwent total mesorectal excision.Cancer staging of ypT0N0 was achieved in 26/170(15.3%)patients.After a median follow-up of 58.3 mo,patients withypT0N0 had five-year disease-free and overall survival rates of 96%(95%CI:77-99)and 100%,respectively.We provide evidence about the natural history of patients with localized rectal cancer achieving a complete response after preoperative chemoradiation.The inherent good prognosis of these patients will have implications for clinical trial design and care of patients.CONCLUSION:Withholding adjuvant chemotherapy after complete response following standard neoadjuvant chemoradiotherapy and laparoscopic mesorectal excision might be safe within an experienced multidisciplinary team. | Xabier García-Albéniz Rosa Gallego Ralf Dieter Hofheinz Gloria Fernández-Esparrach Juan Ramón Ayuso-Colella Josep Antoni Bombí Carles Conill Miriam Cuatrecasas Salvadora Delgado Angels Ginés Rosa Miquel Mario Pagés Estela Pineda Verónica Pereira Aarón Sosa Oscar Reig Iván Victoria Luis Feliz Antonio María de Lacy Antoni Castells Iris Burkholder Andreas Hochhaus Joan Maurel | 2014 | World Journal of Gastroenterology2014，20，42： | 5 |
| 15 | Land cover changes and fragmentation in mountain neotropical ecosystems of Oaxaca, Mexico under community forest management显示文摘Changes in land cover have a direct impact on forest ecosystem goods and services. In this study, changes in land cover in Sierra de Juarez–Oaxaca ecosystems were estimated using a consistent processing of Landsat images and OBIA methodology. Additionally, landscape analyses using FRAGSTAT were conducted. In 2014, Sierra de Juarez–Oaxaca was covered by approximately 84% of forests, mainly pine-oak and cloud forests. After extensive deforestation until 2001, this trend was reversed and the forest cover surface area in 2014 was slightly higher than in 1979. The comparison of the landscape structure of the forested and agricultural lands suggests an increase in habitat heterogeneity. However, interspersion and juxtaposition indices, showing the patch shape by patch area and perimeter, were similar throughout the study period(1979–2014). Social and economic drivers can explain this situation: namely, community organization, forest enterprises, payment for ecosystem services programs, and changes of agricultural activity. Communities in the Sierra of Oaxaca have reforested degraded lands, created community forest enterprises, and preserved the forest under conservation schemes like those proposed by the Mexican payment for ecosystem services programs. However, their sustainable management faces internal challenges and has become highly dependent on political and institutional decisions beyond their control. | Rafael M~a Navarro Cerrillo Dennis J.Esteves Vieira Susana Ochoa-Gaona Bernardus H.J.de Jong M~a del Mar Delgado Serrano | 2019 | Journal of Forestry Research2019，30，1： | 4 |
| 16 | Simulation of Fluid Flow in a Channel Induced by Three Types of Fin-Like Motion显示文摘One of many interesting research activities in biofluidmechanics is dedicated to investigations of locomotion in water. Some of propulsion mechanisms observed in the underwater world are used in the development process of underwater auto-nomic vehicles(AUV). In order to characterise several solutions according to their manoeuvrability,influence on the sur-rounding fluid and energetic efficiency,a detailed analysis of fin-like movement is indispensable. In the current paper an analysis of undulatory,oscillatory and combined fin-like movements by means of numerical simulation is carried out. The conservation equation of mass and the conservation equation of momentum are solved with the Finite Volume Method(FVM) by use of the software CFX-10.0. The undulatory and oscillatory fin movements are modelled with an equation that is implemented within an additional subroutine and joined with the main solver. Numericalsimulations are carried out in the computational domain,in which one fin is fixed in a flow-through water duct. Simulations are carried out in the range of the Re number up to 105. The results show significant influence of applied fin motion on the velocity distribution in the surrounding fluid. | Wojciech Kowalczyk Antonio Delgado | 2007 | Journal of Bionic Engineering2007，4，3： | 4 |

| 20 | CagA EPIYA polymorphisms in Colombian Helicobacter pylori strains and their influence on disease-associated cellular responses显示文摘AIM: To investigate the influence of the CagA diversity in Helicobacter pylori (H. pylori ) strains from Colombia on the host cell biology. METHODS: Eighty-four H. pylori-cagA positive strains with different Glu-Pro-Ile-Tyr-Ala (EPIYA) motifs patterns, isolated from patients with gastritis (n=17), atrophic gastritis (n=17), duodenal ulcer (n=16), intestinal metaplasia (n=16) and gastric cancer (n=18), were included. To determine the integrity of the cag pathogenicity island (cag PAI) we evaluated the presence of cagA, cagT, cagE, and cag10 genes by polymerase chain reaction. AGS gastric epithelial cellswere infected with each strain and assayed for translo-cation and tyrosine phosphorylation of CagA by western blot, secretion of interleukin-8 (IL-8) by enzyme-linked immuno sorbent assay after taking supernatants from cocultures and cell elongation induction. For cell elongation quantification, coculture photographs were taken and the proportion of 'hummingbird' cells (>15 μm) was determined. RESULTS: Overall 72% (60/84) of the strains were found to harbor a functional cag PAI. Levels of phos-phorylated CagA were significantly higher for isolates from duodenal ulcer than the ones in strains from gas-tritis, atrophic gastritis, intestinal metaplasia and gastric cancer (49.1% ± 23.1% vs 21.1% ± 19.5%, P < 0.02; 49.1% ± 23.1% vs 26.2%±14.8%, P<0.045; 49.1% ± 23.1% vs 21.5% ± 19.5%, P<0.043 and 49.1% ± 23.1% vs 29.5% ± 27.1%, P < 0.047 respectively). We observed variable IL-8 expression levels ranging from 0 to 810 pg/mL and from 8.8 to 1442 pg/mL at 6 h and 30 h post-infection, respectively. cagPAI-defective strains did not induce detectable levels of IL-8 at 6 h post-infection. At 30 h post-infection all strains induced IL-8 expression in AGS cells, although cagPAI-defective strains induced significantly lower levels of IL-8 than strains with a functional cagPAI (57.1 ± 56.6 pg/mL vs 513.6 ± 338.6 pg/mL,P < 0.0001). We did not observe differences in the extent of cell elongation induction between strains with a functional or a defective cagPAI in 6 h cocultures. At 24 h post infection strains with functionalcagPAI showed high diversity in the extent of hummingbird phenotype induction ranging from 7% to 34%. cag PAI defective strains induced significantly lower levels of elongation than strains with functional cag-PAI with one or more than one EPIYA-C motif (15.1% ± 5.2%vs 18.9% ± 4.7%,P < 0.03; and 15.1% ± 5.2% vs 20.0% ± 5.1%, P < 0.003 respectively). No differences were observed in cellular elongation inductionor IL-8 expression among H. pylori strains bearing one and more than one EPIYA-C motifs, neither at 6 h nor at 24 h of coculture. There were no associations between the levels of induction of cell elongation or IL-8 expression and number of EPIYA motifs or pathology. CONCLUSION: The present work describes a lack of association between H. pylori CagA protein EPIYA motifs variations from Colombian isolates and disease-associated cellular responses. | Carlos Alberto Fajardo Andrés Javier Quiroga Andrea Coronado Karen Labrador Nicole Acosta Pilar Delgado Carlos Jaramillo María Mercedes Bravo | 2013 | World Journal of Gastrointestinal Oncology2013，5，3： | 3 |
