| 1 | Microbiota modification by probiotic supplementation reduces colitis associated colon cancer in mice显示文摘AIM To investigate the effect of probiotic supplementation during the development of an experimental model of colitis associated colon cancer(CAC). METHODS C57 BL/6 mice received an intraperitoneal injection of azoxymethane(10 mg/kg), followed by three cycles of sodium dextran sulphate diluted in water(5% w/v). Probiotic group received daily a mixture of Lactobacillus acidophilus, Lactobacil us rhamnosus and Bifidobacterium bifidum. Microbiota composition was assessed by 16 Sr RNA Illumina Hi Seq sequencing. Colon samples were collected for histological analysis. Tumor cytokines was assessed by Real Time-PCR(Polymerase Chain Reaction); and serum cytokines by Multiplex assay. All tests were two-sided. The level of significance was set at P < 0.05. Graphs were generated and statistical analysis performed using the software Graph Pad Prism 5.0. The project was approved by the institutional review board committee. RESULTS At day 60 after azoxymethane injection, the mean number of tumours in the probiotic group was 40% lower than that in the control group, and the probiotic group exhibited tumours of smaller size(< 2 mm)(P < 0.05). There was no difference in richness and diversity between groups. However, there was a significant difference in beta diversity in the multidimensional scaling analysis. The abundance of the genera Lactobacillus, Bifidobacterium, Allobaculum, Clostridium XI and Clostridium XVⅢ increased in the probiotic group(P < 0.05). The microbial change was accompanied by reduced colitis, demonstrated by a 46% reduction in the colon inflammatory index; reduced expression of the serum chemokines RANTES and Eotaxin; decreased p-IKK and TNF-α and increased IL-10 expression in the colon. CONCLUSION Our results suggest a potential chemopreventive effect of probiotic on CAC. Probiotic supplementation changes microbiota structure and regulates the inflammatory response, reducing colitis and preventing CAC. | Maria Carolina S Mendes Daiane SM Paulino Sandra R Brambilla Juliana A Camargo Gabriela F Persinoti José Barreto C Carvalheira | 2018 | World Journal of Gastroenterology2018，24，18： | 17 |
| 2 | Transhiatal versus transthoracic esophagectomy for esophageal cancer显示文摘Esophageal cancer continues to represent a formidable challenge for both patients and clinicians. Relative 5-year survival rates for patients have improved over the past three decades, probably linked to a combination of improved surgical outcomes, progress in systemic chemotherapy and radiotherapy, and the increasing acceptance of multimodality treatment. Surgical treatment remains a fundamental component of the treatment of localized esophageal adenocarcinoma. Multiple approaches have been described for esophagectomy, which can be thematically grouped under two major categories: either transthoracic or transhiatal. The main controversy rests on whether a more extended resection through thoracotomy provides superior oncological outcomes as opposed to resection with relatively limited morbidity and mortality through a transhiatal approach. After numerous trials have addressed these issues, neither approach has consistently proven to be superior to the other one, and both can provide excellent short-term results in the hands of experienced surgeons. Moreover, the available literature suggests that experience of the surgeonand hospital in the surgical management of esophageal cancer is an important factor for operative morbidity and mortality rates, which could supersede the type of approach selected. Oncological outcomes appear to be similar after both procedures. | J Camilo Barreto Mitchell C Posner | 2010 | World Journal of Gastroenterology2010，16，30： | 16 |
| 3 | Analysis of the delayed approach to the management of infected pancreatic necrosis显示文摘AIM: To analyze outcomes of delayed single-stage necrosectomy after early conservative management of patients with infected pancreatic necrosis (IPN) associated with severe acute pancreatitis (SAP). METHODS: Between January 1998 and December 2009, data from patients with SAP who developed IPN and were managed by pancreatic necrosectomy were analyzed. RESULTS: Fifty-nine of 61 pancreatic necrosectomies were performed by open surgery and 2 laparoscopically. In 55 patients, single-stage necrosectomy could be performed (90.2%). Patients underwent surgery at a median of 29 d (range 13-46 d) after diagnosis of acute pancreatitis. Sepsis and multiple organ failure accounted for the 9.8% mortality rate. Pancreatic fistulae (50.8%) predominantly accounted for the morbidity. The median hospital stay was 23 d, and the median interval for return to regular activities was 110 d.CONCLUSION: This series supports the concept of delayed single-stage open pancreatic necrosectomy for IPN. Advances in critical care, antibiotics and interventional radiology have played complementary role in improving the outcomes. | Nilesh Doctor Sujith Philip Vidhyachandra Gandhi Maharra Hussain Savio G Barreto | 2011 | World Journal of Gastroenterology2011，17，3： | 15 |
| 4 | Neuroprotective effects of minocycline on focal cerebral ischemia injury: a systematic review显示文摘To review the neuroprotective effects of minocycline in focal cerebral ischemia in animal models.By searching in the databases of PubMed,ScienceDirect,and Scopus,and considering the inclusion and exclusion criteria of the study.Studies were included if focal cerebral ischemia model was performed in mammals and including a control group that has been compared with a minocycline group.Written in languages other than English;duplicate data;in vitro studies and combination of minocycline with other neuroprotective agents were excluded.Neurological function of patients was assessed by National Institute of Health Stroke Scale,modified Rankin Scale,and modified Barthel Index.Neuroprotective effects were assessed by detecting the expression of inflammatory cytokines.We examined 35 papers concerning the protective effects of minocycline in focal cerebral ischemia in animal models and 6 clinical trials which had evaluated the neuroprotective effects of minocycline in ischemic stroke.These studies revealed that minocycline increases the viability of neurons and decreases the infarct volume following cerebral ischemia.The mechanisms that were reported in these studies included anti-inflammatory,antioxidant,as well as anti-apoptotic effects.Minocycline also increases the neuronal regeneration following cerebral ischemia.Minocycline has considerable neuroprotective effects against cerebral ischemia-induced neuronal damages.However,larger clinical trials may be required before using minocycline as a neuroprotective drug in ischemic stroke. | Yazdan Naderi Yunes Panahi George E.

| 5 | Chemical,Sensorial and Rheological Properties of a New Organic Rice Bran Beverage显示文摘Rice bran is a solid residue from rice polishing that is used in animal nutrition and rice oil production. Cultivation conditions with agro-toxics, lipids instability, and tendency for mycotoxin contamination restrict its application in human nutrition. Therefore, organic agriculture is an alternative to use the properties of rice bran. Rice bran beverage is a new cereal product from organic rice. This work presents the preliminary results of the chemical and rheological studies of a bath pasteurized rice bran beverage. Compared with integral defatted milk, soy extracts, and brown rice low-fat milk, the rice bran beverage studied in this work presents itself as an important source of minerals and unsaturated lipids. All essential amino acids were found in this product. Glutamic and aspartic acids were predominant. Bath pasteurization at boiling water temperature for 15 and 30 min was adequate for microbiological safety. Refrigeration storage for 20 days, evaluated by pH and acidity variations, was ideal for assessment of the beverage conservation time. The beverage viscosity was of the Newtonian standard behavior, and its viscosity during storage was not a good parameter to evaluate shelf life. Sensory preference tests showed positive perspectives for this new beverage. | Gerson Luis FACCIN Leila do Nascimento VIEIRA Letícia Adélia MIOTTo Pedro Luiz Manique BARRETO Edna Regina AMANTE | 2009 | Rice science2009，16，3： | 9 |
| 6 | Fetal brain tumors:Prenatal diagnosis by ultrasound and magnetic resonance imaging显示文摘Congenital central nervous system tumors diagnosed during pregnancy are rare, and often have a poor prognosis. The most frequent type is the teratoma. Use of ultrasound and magnetic resonance image allows the suspicion of brain tumors during pregnancy. However, the definitive diagnosis is only confirmed after birth by histology. The purpose of this mini-review article is to describe the general clinical aspects of intracranial tumors and describe the main fetal brain tumors. | Herbene Jose Milani Edward Araujo Junior Sergio Cavalheiro Patrícia Soares Oliveira Wagner Jou Hisaba Enoch Quindere Sa Barreto Maurício Mendes Barbosa Luciano Marcondes Nardozza Antonio Fernandes Moron | 2015 | World Journal of Radiology2015，7，1： | 7 |
| 7 | Reallocation of foliicolous species of the genus Strigula into six genera(lichenized Ascomycota,Dothideomycetes,Strigulaceae)显示文摘Strigula sensu lato has been previously defined based on phenotype characters as a rather broad genus including tropical to temperate species growing on a wide array of substrata.In this study,based on a multilocus phylogenetic approach,we show that foliicolous species form six well-delimited clades that correlate with diagnostic phenotype features,including thallus morphology,carbonization of the involucrellum and excipulum,ascospore dimensions,and type of macroconidia.Given the topology,with five of the six clades emerging on long stem branches,and the strong phenotypical differentiation between the clades,we recognize these at the genus level,making mostly use of previously established genus names.Four genera,namely Phylloporis,Puiggariella,Raciborskiella,and Racoplaca,are resurrected for the S.phyllogena,S.nemathora,S.janeirensis,and S.subtilissima groups,respectively,whereas one new genus,Serusiauxiella gen.nov.,is introduced for a novel lineage with peculiar macroconidia.The only sequenced non-foliicolous species,S.jamesii,is not closely related to these six foliicolous lineages but clusters with Flavobathelium and Phyllobathelium,revealing it as an additional undescribed genus-level lineage being treated elsewhere.Within the new genus Serusiauxiella,three new species are described:Serusiauxiella filifera sp.nov.,S.flagellata sp.nov.,and S.sinensis sp.nov.In addition,ten new combinations are proposed:Phylloporis austropunctata comb.nov.,P.radiata comb.nov.,P.vulgaris comb.nov.,Puiggariella confluens comb.et stat.nov.,P.nemathora comb.nov.,P.nigrocincta comb.nov.,Racoplaca maculata comb.nov.,R.melanobapha comb.nov.,R.transversoundulata,and R.tremens comb.nov.We also report on a peculiar,previously unrecognized growth behaviour of the macroconidial appendages in Strigula s.lat. | Shu‑Hua Jiang Robert Lücking Amanda Barreto Xavier‑Leite Marcela E.S.Cáceres AndréAptroot Carlos Vinas Portilla Jiang‑Chun Wei | 2020 | Fungal Diversity2020，，3： | 5 |
| 8 | Repurposing metformin for the treatment of gastrointestinal cancer显示文摘Diabetes mellitus type 2 and cancer share many risk factors.The pleiotropic insulin-dependent and insulin-independent effects of metformin might inhibit pathways that are frequently amplified in neoplastic tissue.Particularly,modulation of inflammation,metabolism,and cell cycle arrest are potential therapeutic cancer targets utilized by metformin to boost the anti-cancer effects of chemotherapy.Studies in vitro and in vivo models have demonstrated the potential of metformin as a chemo-and radiosensitizer,besides its chemopreventive and direct therapeutic activity in digestive system(DS)tumors.Hence,these aspects have been considered in many cancer clinical trials.Case-control and cohort studies and associated meta-analyses have evaluated DS cancer risk and metformin usage,especially in colorectal cancer,pancreatic cancer,and hepatocellular carcinoma.Most clinical studies have demonstrated the protective role of metformin in the risk for DS cancers and survival rates.On the other hand,the ability of metformin to enhance the actions of chemotherapy for gastric and biliary cancers is yet to be investigated.This article reviews the current findings on the anti-cancer mechanisms of metformin and its apparatus from pre-clinical and ongoing studies in DS malignancies. | Ademar Dantas Cunha Júnior Arinilda Campos Bragagnoli Felipe Osório Costa JoséBarreto Campello Carvalheira | 2021 | World Journal of Gastroenterology2021，27，17： | 5 |
| 9 | Pioneering function of Isl1 in the epigenetic control of cardiomyocyte cell fate显示文摘Generation of widely differing and specialized cell types from a single totipotent zygote involves large-scale transcriptional changes and chromatin reorganization. Pioneer transcription factors play key roles in programming the epigenome and facilitating recruitment of additional regulatory factors during successive cell lineage specification and differentiation steps. Here we show that Isl1 acts as a pioneer factor driving cardiomyocyte lineage commitment by shaping the chromatin landscape of cardiac progenitor cells. Using an Isl1 hypomorphic mouse line which shows congenital heart defects, genome-wide profiling of Isl1 binding together with RNA- and ATAC-sequencing of cardiac progenitor cells and their derivatives, we uncover a regulatory network downstream of Isl1 that orchestrates cardiogenesis. Mechanistically, we show that Isl1 binds to compacted chromatin and works in concert with the Brg1-Baf60c-based SWI/SNF complex to promote permissive cardiac lineage-specific alterations in the chromatin landscape not only of genes with critical functions in cardiac progenitor cells, but also of cardiomyocyte structural genes that are highly expressed when Isl1 itself is no longer present. Thus, the Isl1/Brg1-Baf60c complex plays a crucial role in orchestrating proper cardiogenesis and in establishing epigenetic memory of cardiomyocyte fate commitment. | Rui Gao Xingqun Liang Sirisha Cheedipudi Julio Cordero Xue Jiang Qingquan Zhang Luca Caputo Stefan Günther Carsten Kuenne Yonggang Ren Shoumo Bhattacharya Xuejun Yuan Guillermo Barreto Yihan Chen Thomas Braun Sylvia M.

| 16 | Extended pancreatic resections and lymphadenectomy:An appraisal of the current evidence显示文摘Surgery remains the mainstay of treatment for pancreatic ductal adenocarcinoma and complete removal of the cancer confers a definite survival advantage,especially in early disease.However,the majority of patients do not present with early disease,thus precluding the chance of a cure by standard pancreatoduodenectomy(PD),distal pancreatectomy or total pancreatectomy.For this reason,pancreatic surgeons have attempted to push the limits of resection over the last three decades.The aim of these resections has been to determine whether obtaining a complete resection by extending the limits of conventional resection in patients with advanced disease will yield the results seen with PD alone in early disease.This article revisits the data from such studies in an attempt to determine if the available literature supports the performance of extended resections for pancreatic cancer in terms of improvement of survival. | Shailesh V Shrikhande Savio G Barreto | 2010 | World Journal of Gastrointestinal Surgery2010，2，2： | 2 |

| 18 | Cell-type specificity of β-actin expression and its clinicopathological correlation in gastric adenocarcinoma显示文摘AIM:To investigate cell type specific distribution ofβ-actin expression in gastric adenocarcinoma and its correlation with clinicopathological parameters.METHODS:β-actin is a housekeeping gene,frequently used as loading control,but,differentially expresses in cancer.In gastric cancer,an overall increased expression ofβ-actin has been reported using tissue disruptive techniques.At present,no histological data is available to indicate its cell type-specific expression and distribution pattern.In the present study,we analyzedβ-actin expression and distribution in paired normal and tumor tissue samples of gastric adenocarcinoma patients using immunohistochemistry(IHC),a tissue non-disruptive technique as well as tissue disruptive techniques like reverse transcriptase-polymerase chain reaction(RT-PCR)and western blotting.Correlation ofβ-actin level with clinicopathological parameters was done using univariate analysis.RESULTS:The results of this study showed significant overexpression,at both mRNA and protein level in tumor tissues as confirmed by RT-PCR(1.47±0.13 vs2.36±0.16;P<0.001)and western blotting(1.92±0.26 vs 2.88±0.32;P<0.01).IHC revealed thatβ-actin expression is majorly distributed between epithelial and inflammatory cells of the tissues.Inflammatory cells showed a significantly higher expression compared to epithelial cells in normal(2.46±0.13 vs 5.92±0.23,P<0.001),as well as,in tumor tissues(2.79±0.24 vs6.71±0.14,P<0.001).Further,comparison of immunostaining between normal and tumor tissues revealed that both epithelial and inflammatory cells overexpressβ-actin in tumor tissues,however,significant difference was observed only in inflammatory cells(5.92±0.23vs 6.71±0.14,P<0.01).Moreover,combined expression in epithelial and inflammatory cells also showed significant increase(4.19±0.15 vs 4.75±0.14,P<0.05)in tumor tissues.In addition,univariate analysis showed a positive correlation ofβ-actin level of inflammatory cells with tumor grade(P<0.05)while epithelial cells exhibited negative correlation(P>0.05).CONCLUSION:In gastric cancer,β-actin showed an overall higher expression predominantly contributed by inflammatory or tumor infiltrating immune cells of the tissue microenvironment and correlates with tumor grade. | Shafqat A Khan Monica Tyagi Ajit K Sharma Savio G Barreto Bhawna Sirohi Mukta Ramadwar Shailesh V Shrikhande Sanjay Gupta | 2014 | World Journal of Gastroenterology2014，20，34： | 2 |
| 19 | Systematic review and meta-analysis of the impact of deviations from a clinical pathway on outcomes following pancreatoduodenectomy显示文摘BACKGROUND Enhanced recovery after surgery is steadily gaining importance in patients undergoing pancreatic surgery,including pancreatoduodenectomy(PD).While clinical pathways targeting enhanced-recovery can achieve their intended outcome in reducing length of stay,compliance to these pathways,and their relevance is poorly understood.The aim of this systematic review was to assess the impact of deviations from/non-compliance to a clinical pathway on post-PD outcomes.AIM To assess the impact of deviations from/non-compliance to a clinical pathway on post-PD outcomes.METHODS A systematic review of major reference databases was undertaken,according to preferred reporting items for systematic reviews and meta-analysis guidelines,between January 2000 and November 2020 relating to compliance with clinical pathways and its impact on outcomes in patients undergoing PD.A meta-analysis was performed using fixed-effects or random-effects models.RESULTS Eleven studies including 1852 patients were identified.Median overall compliance to all components of the clinical pathway was 65.7%[interquartile range(IQR):62.7%-72.3%]with median compliance to post-operative parameters of the clinical pathway being 44%(IQR:34.5%-52.25%).Meta-analysis using a fixed-effects model showed that≥50%compliance to a clinical pathway predicted significantly fewer post-operative complications[pooled odds ratio(OR):9.46,95%confidence interval(CI):5.00-17.90;P<0.00001]and a significantly shorter length of hospital stay[pooled mean difference(MD):4.32,95%CI:-3.88 to-4.75;P<0.0001].At 100%compliance which was associated with significantly fewer post-operative complications(pooled OR:11.25,95%CI:4.71-26.84;P<0.00001)and shorter hospital stay(pooled MD of 4.66,95%CI:2.81-6.51;P<0.00001).CONCLUSION Compliance to post-PD clinical pathways remains low.Deviations are associated with an increased risk of complications and length of hospital stay.Understanding the relevance of deviations to clinical pathways post-PD presents pancreatic surgeons with opportunities to actively pursue an enhanced-recovery of their patients. | Monish Karunakaran Pavan Kumar Jonnada Savio George Barreto | 2021 | World Journal of Clinical Cases2021，9，13： | 2 |
| 20 | Developmental hemostasis in the neonatal period显示文摘Background The hemostatic system is complex and evolves continuously since gestation and well into the adult years,in a process known as“developmental hemostasis.”Data sources A comprehensive review was performed after an extensive literature search on PubMed/MEDLINE concerning developmental hemostasis during the neonatal period.Relevant cross references were also included.Results Although part of a system,each component of the hemostatic system evolves differently,with many displaying both quantitative and qualitative age-related differences.This leads to drastic disparities between the coagulation system of neonates and both other children’s and adults’,while still maintaining a generally balanced and physiological hemostasis.The motives behind this process remain to be fully elucidated but may be,at least in part,related to non-hemostatic factors.Conclusions Knowledge regarding“developmental hemostasis”is essential for everyone caring for newborns or even children in general and in this review,we describe each hemostatic system component’s neonatal characteristics and age-related progression as well as explore some of the possible physiological motives behind the process. | Vicente Rey y Formoso Ricardo Barreto Mota Henrique Soares | 2022 | World Journal of Pediatrics2022，18，1： | 2 |
