| 1 | The timing of bowel preparation before colonoscopy determines the quality of cleansing,and is a significant factor contributing to the detection of flat lesions:A randomized study显示文摘AIM: To compare the cleansing quality of polyethylene glycol electrolyte solution and sodium phosphate with different schedules of administration, and to evaluate whether the timing of the administration of bowel preparation affects the detection of polyps. METHODS: One hundred and seventy-seven consecutive outpatients scheduled for colonoscopy were randomized in one of four groups to receive polyethylene glycol electrolyte solution or oral sodium phosphate with two different timing schedules. Quality of cleansing, polyp detection, and tolerance were evaluated. RESULTS: Patients receiving polyethylene glycol or sodium phosphate on the same day as the colonoscopy, obtained good to excellent global cleansing scores more frequently than patients who received polyethylene glycol or sodium phosphate on the day prior to the procedure (P < 0.001). Flat lesions, but not flat adenomas, were more frequent in patients prepared on the same day (P = 0.02). CONCLUSION: The quality of colonic cleansing and the detection of flat lesions are significantly improved when the preparation is taken on the day of the colonoscopy. | Adolfo Parra-Blanco David Nicolás-Pérez Antonio Gimeno-García Begoa Grosso Alejandro Jiménez Juan Ortega Enrique Quintero | 2006 | World Journal of Gastroenterology2006，12，38： | 19 |
| 2 | Validation of Fujinon intelligent chromoendoscopy with high definition endoscopes in colonoscopy显示文摘AIM:To validate high definition endoscopes with Fujinon intelligent chromoendoscopy(FICE) in colonoscopy.METHODS:The image quality of normal white light endoscopy(WLE),that of the 10 available FICE filters and that of a gold standard(0.2% indigo carmine dye) were compared.RESULTS:FICE-filter 4 [red,green,and blue(RGB) wavelengths of 520,500,and 405 nm,respectively] provided the best images for evaluating the vascular pattern compared to white light.The mucosal surface was best assessed using filter 4.However,the views obtained were not rated significantly better than those observed with white light.The 'gold standard',indigo carmine(IC) dye,was found to be superior to both white light and filter 4.Filter 6(RGB wavelengths of 580,520,and 460 nm,respectively) allowed for exploration of the IC-stained mucosa.When assessing mucosal polyps,both FICE with magnification,and magnification following dye spraying were superior to the same techniques without magnification and to white light imaging.In the presence of suboptimal bowel preparation,observation with the FICE mode was possible,and endoscopists considered it to be superior to observation with white light.CONCLUSION:FICE-filter 4 with magnification improves the image quality of the colonic vascular patterns obtained with WLE. | Adolfo Parra-Blanco Alejandro Jiménez Bjrn Rembacken Nicolás González David Nicolás-Pérez Antonio Z Gimeno-García Marta Carrillo-Palau Takahisa Matsuda Enrique Quintero | 2009 | World Journal of Gastroenterology2009，15，42： | 12 |
| 3 | Attenuation of dextran sodium sulphate induced colitis in matrix metalloproteinase-9 deficient mice显示文摘AIM: To study whether matrix metalloproteinase-9 (MMP-9) is a key factor in epithelial damage in the dextran sodium sulphate (DSS) model of colitis in mice.METHODS: MMP-9-deficient and wild-type (wt) mice were given 5% DSS in drinking water for 5 d followed by recovery up to 7 d. On d 5 and 12 after induction of colitis, gelatinases, MMP-2 and MMP-9, were measured in homogenates of colonic tissue by zymography and Western blot, whereas tissue inhibitor of metalloproteinases (TIMPs) were measured by reverse zymography. The gelatinolytic activity was also determined in supernatants of polymorphonuclear leukocytes (PMN) isolated from mice blood. Moreover, intestinal epithelial cells were stimulated with TNF-α to study whether these cells were able to produce MMPs. Finally, colonic mucosal lesions were measured by microscopic examination. RESULTS: On d 5 of colitis, the activity of MMP-9 was increased in homogenates of colonic tissues (0.24 ± 0.1 vs 21.3 ± 6.4, P < 0.05) and PMN from peripheral blood in wt (0.5 ± 0.1 vs 10.4 ± 0.7, P < 0.05), but not in MMP-9-deficient animals. The MMP-9 activity was also up-regulated by TNF-α in epithelial intestinal cells (2.5 ± 0.5 vs 14.7 ± 3.0, P < 0.05). Although colitis also led to increase of TIMP-1 activity, the MMP-9/TIMP-1 balance remained elevated. Finally, in the MMP-9-deficient colitic mice both the extent and severity of intestinal epithelialinjury were significantly attenuated when compared with wt mice. CONCLUSION: We conclude that DSS induced colitis is markedly attenuated in animals lacking MMP-9. This suggests that intestinal injury induced by DSS is modu-lated by MMP-9 and that inhibition of this gelatinase may reduce inflammation. | Alfredo Santana Carlos Medina Maria Cristina Paz-Cabrera Federico Díaz-Gonzalez Esther Farré Antonio Salas Marek W Radomski Enrique Quintero | 2006 | World Journal of Gastroenterology2006，12，40： | 9 |
| 4 | 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 |
| 5 | Gallbladder cancer:Historical treatment and new management options显示文摘Gallbladder cancer is a rare,aggressive malignancy that has a poor overall prognosis.Effective treatment consists of early detection and surgical treatment.With the wide spread treatment of gallbladder disease with minimally invasive techniques,the rate of incidental gallbladder cancer has seen an equitable rise along with stage migration towards earlier disease.Although the treatment remains mostly surgical,newer modalities such as regional therapy as well as directed therapy based on molecular medicine has led to improved outcomes in patients with advanced disease.We aim to summarize the management of gallbladder cancer along with the newer developments in this formidable disease process. | Kenji Okumura Shekhar Gogna Mahir Gachabayov Daniel Moritz Felsenreich Matthew McGuirk AramRojas Luis Quintero Ramanathan Seshadri Katie Gu Xiang Da Dong | 2021 | World Journal of Gastrointestinal Oncology2021，13，10： | 5 |
| 6 | Identification of ta-siRNAs and Cis-nat-siRNAs in Cassava and Their Roles in Response to Cassava Bacterial Blight显示文摘Trans-acting small interfering RNAs (ta-siRNAs) and natural cis-antisense siRNAs (cis-nat-siRNAs) are recently discovered small RNAs (sRNAs) involved in post-transcriptional gene silencing. ta-siRNAs are transcribed from genomic loci and require processing by microRNAs (miRNAs). cis-nat-siRNAs are derived from antisense RNAs produced by the simultaneous transcription of overlapping antisense genes. Their roles in many plant processes, including pathogen response, are mostly unknown. In this work, we employed a bioinformatic approach to identify ta-siRNAs and cis-nat-siRNAs in cassava from two sRNA libraries, one constructed from healthy cassava plants and one from plants inoculated with the bacterium Xanthomonas axonopodis pv.manihotis (Xam). A total of 54 possible ta-siRNA loci were identified in cassava, including a homolog of TAS3, the best studied plant ta-siRNA. Fifteen of these loci were induced, while 39 were repressed in response to Xam infection. In addition, 15 possible cis-natural antisense transcript (cis-NAT) loci producing siRNAs were identified from overlapping antisense regions in the genome,and were found to be differentially expressed upon Xam infection. Roles of sRNAs were predicted by sequence complementarity and our results showed that many sRNAs identified in this work might be directed against various transcription factors. This work represents a significant step toward understanding the roles of sRNAs in the immune response of cassava. | Andrés Quintero Alvaro L.

| 7 | Harnessing digital workflows for the understanding,promotion and participation in the conservation of heritage sites by meeting both ethical and technical challenges显示文摘The current application of digital workflows for the understanding,promotion and participation in the conservation of heritage sites involves several technical challenges and should be governed by serious ethical engagement.Recording consists of capturing(or mapping)the physical characteristics of character-defining elements that provide the significance of cultural heritage sites.Usually,the outcome of this work represents the cornerstone information serving for their conservation,whatever it uses actively for maintaining them or for ensuring a posterity record in case of destruction.The records produced could guide the decision-making process at different levels by property owners,site managers,public officials,and conservators around the world,as well as to present historical knowledge and values of these resources.Rigorous documentation may also serve a broader purpose:over time,it becomes the primary means by which scholars and the public apprehends a site that has since changed radically or disappeared.This contribution is aimed at providing an overview of the potential application and threats of technology utilised by a heritage recording professional by addressing the need to develop ethical principles that can improve the heritage recording practice at large. | Mario Santana Quintero Reem Awad Luigi Barazzetti | 2020 | Built Heritage2020，4，1： | 3 |
