1Autoimmune hepatitis and anti-tumor necrosis factor alpha therapy:A single center report of 8 cases显示文摘This article describes cases of anti-tumor necrosis factor(TNF)-α-induced autoimmune hepatitis and evaluates the outcome of these patients in relation to their immunosuppressive strategy. A retrospective analysis of medical records was performed in our center, in order to detect cases of autoimmune hepatitis(AIH) associated with anti-TNF biologic agents. We describe and analyze eight cases of AIH following anti-TNF therapy, 7 with infliximab and 1 with adalimumab. A distinction should be made between induction of autoimmunity and clinically evident autoimmune disease. Liver biopsy is useful in detecting the role of the TNF-α antagonist in the development of AIH. The lack of relapse after discontinuing immunosuppressive therapy favors, as in this case series, an immune-mediated drug reaction as most patients with AIH have a relapse after treatment is suspended. Although AIH related to anti-TNF therapy is rare, a baseline immunological panel along with liver function tests should be performed in all patients with autoimmune disease before starting biologics.Susana Rodrigues Susana Lopes Fernando Magro Hélder Cardoso Ana Maria Horta e Vale Margarida Marques Eva Mariz Miguel Bernardes Joanne Lopes Fátima Carneiro Guilherme Macedo 2015World Journal of Gastroenterology2015,21,24:9
2Multidimensional Projections for Visual Analysis of Social Networks显示文摘Visual analysis of social networks is usually based on graph drawing algorithms and tools.However,social networks are a special kind of graph in the sense that interpretation of displayed relationships is heavily dependent on context.Context,in its turn,is given by attributes associated with graph elements,such as individual nodes,edges,and groups of edges,as well as by the nature of the connections between individuals.In most systems,attributes of individuals and communities are not taken into consideration during graph layout,except to derive weights for force-based placement strategies.This paper proposes a set of novel tools for displaying and exploring social networks based on attribute and connectivity mappings.These properties are employed to layout nodes on the plane via multidimensional projection techniques.For the attribute mapping,we show that node proximity in the layout corresponds to similarity in attribute,leading to easiness in locating similar groups of nodes.The projection based on connectivity yields an initial placement that forgoes force-based or graph analysis algorithm,reaching a meaningful layout in one pass.When a force algorithm is then applied to this initial mapping,the final layout presents better properties than conventional force-based approaches.Numerical evaluations show a number of advantages of pre-mapping points via projections.User evaluation demonstrates that these tools promote ease of manipulation as well as fast identification of concepts and associations which cannot be easily expressed by conventional graph visualization alone.In order to allow better space usage for complex networks,a graph mapping on the surface of a sphere is also implemented.Rafael Messias Martins Gabriel Faria Andery Henry Heberle Fernando Vieira Paulovich Alneu de Andrade Lopes Helio Pedrini Rosane Minghim 2012Journal of Computer Science & Technology2012,27,4:6
3Extramedullary plasmocytoma associated with a massive deposit of amyloid in the duodenum显示文摘We report a rare case of extramedullary plasmocytoma associated with a massive deposit of amyloid in the duodenum.A 72-year-old Japanese man was admitted to our hospital presenting with a 3-mo history of epigastric pain, vomiting and weight loss.On computed tomography(CT) a wall thickening of the fourth part of the duodenum was observed.Multiple biopsies obtained from the lesion showed inflltration of plasma cells and lymphocytes, but they were not conclusive.The patient underwent resection of the lesion and, on histopathological examination, the lesion consisted of a dense and diffuse inflltrate of plasma cells and a few admixed lymphocytes with reactive follicles extending to the muscular propria.An extensive deposition of amyloid was also observed.Immunohistochemical stains revealed that a few plasmacytoid cells showed λ light chain staining, though most were κ light chain positive.These cells also were positive for CD138 and CD56 but negative for CD20 and CD79.The flndings were consistent with extramedullary plasmocytomaassociated with a massive deposit of amyloid in duodenum.A subsequent workup for multiple myeloma was completely negative.The patient showed no signs of local recurrence or dissemination of the disease after 12 mo follow-up.Because of the association of plasmocytoma and amyloidosis, the patient must be followed up because of the possible systemic involvement of the neoplasm and amyloidosis in future.Fabiana Pirani Carneiro Maria de Nazareth Machado Sobreira Lívia Bravo Maia Alesso Cervantes Sartorelli Luiz Eduardo de Almeida Prado Franceschi Mauro Brito Brando Bárbara Wosnjuk Calaca Fernando Silva Lustosa Joo Vieira Lopes 2009World Journal of Gastroenterology2009,15,28:2
4Characterization of goat whey proteins and their bioactivity and toxicity assay显示文摘Goat whey is an industry-discarded dairy by-product that has interesting nutritional value and a nutrient composition with important functional potential,where proteins have a high biological value and play an important role in the organism’s physiology.Therefore,the aim of this study was to identify,quantify,concentrate and investigate the capacity of goat whey proteins to perform different biological activities and to evaluate their acute toxicity.Concentrated proteins were quantified and identified by Bradford,Kjehdal and SDS-PAGE methods.Antibacterial activity was performed against Listeria monocytogenes,Salmonella spp.,Staphylococcus aureus,Pseudomonas aeruginosa and Escherichia coli microorganisms and showed MIC ranging from 15 to 120μg mL-1,with the highest inhibition for L.monocytogenes growth.Antiproliferative activity was performed against human malignant melanoma cells and their proliferation inhibition was up to 66.8%within 72 h of exposure.The highest antioxidant capacity was obtained at concentration 2 mg that showed 29.69%of inhibition of DPPH radical oxidation.The acute toxicity test was performed using Artemia franciscana larvae in which whey proteins were able to preserve larval survival throughout exposure.Thus,we can conclude that goat’s whey has proteins that can play a positive effect on health,with antimicrobial activity and without toxicity.The present study highlights the great potential of goat’s whey to be developed as a safe biopreservative or as a functional ingredient in the food industry.Maria Isabel Ferreira Campos Paula Perazzo de Souza Barbosa Laura Junqueira Camargo Luciano Da Silva Pinto Bianca Mataribu Catarina Serr˜ao Luis Fernando Marques-Santos Jos´e Hon´orio Lopes Julia Mariano Caju de Oliveira Carlos Alberto de Almeida Gadelha Tatiane Santi-Gadelha 2022Food Bioscience2022,46,2:2

11Gastroesophageal reflux disease and non-esophageal cancer显示文摘The association of gastroesophageal reflux disease(GERD) and esophageal cancer is well known.The carcinogenic properties of the gastroduodenal contents may also lead to cancer in target organs for GERD especially considering that they do not have intrinsic protective mechanisms as found in the esophagus.This review focuses on the putative relation between GERD and non-esophageal cancer.Most of the papers reviewed are far from ideal to prove the relationship of extraesophageal cancer and GERD since a small number ofpatients is presented,most do not control cases based on tobacco usage and obesity,and the diagnosis of GERD is variable,not always from an objective measurement such as p H monitoring but relying on symptoms in most reports.Nevertheless,head and neck and lung cancer have a growing incidence parallel to GERD and a shift towards non-smoking,female gender and adenocarcinoma(compared to squamous cell carcinoma) is arising,similar to the example of esophageal cancer with the exception of the female gender.Fernando AM Herbella Sebastiao Pannocchia Neto Ilka Lopes Santoro Licia Caldas Figueiredo 2015World Journal of Gastroenterology2015,21,3:1

13Proposed nomenclature for Pseudallescheria,Scedosporium and related genera显示文摘As a result of fundamental changes in the International Code of Nomenclature on the use of separate names for sexual and asexual stages of fungi,generic names of many groups should be reconsidered.Members of the ECMM/ISHAM working group on Pseudallescheria/Scedosporium infections herein advocate a novel nomenclature for genera and species in Pseudallescheria,Scedosporium and allied taxa.The generic names Parascedosporium,Lomentospora,Petriella,Petriellopsis,and Scedosporium are proposed for a lineage within Microascaceae with mostly Scedosporium anamorphs producing slimy,annellidic conidia.Considering that Scedosporium has priority over Pseudallescheria and that Scedosporium prolificans is phylogenetically distinct from the other Scedosporium species,some name changes are proposed.Pseudallescheria minutispora and Petriellidium desertorum are renamed as Scedosporium minutisporum and S.desertorum,respectively.Scedosporium prolificans is renamed as Lomentospora prolificans.Michaela Lackner G.Sybren de Hoog Liyue Yang Leandro Ferreira Moreno Sarah A.Ahmed Fritz Andreas Josef Kaltseis Markus Nagl Cornelia Lass-Florl Brigitte Risslegger Gunter Rambach Cornelia Speth Vincent Robert Walter Buzina Sharon Chen Jean-Philippe Bouchara Jose F.Cano-Lira Josep Guarro Josepa Gené Fabiola Fernández Silva Rosa Haido Gerhard Haase Vladimir Havlicek Dea Garcia-Hermoso Jacques F.Meis Ferry Hagen Martin Kirchmair Johannes Rainer Katharina Schwabenbauer Mirjam Zoderer Wieland Meyer Felix Gilgado Vania A.Vicente Elena Piecková Monika Regenermel Peter-Michael Rath Joerg Steinmann Xisto Wellington de Alencar Francoise Symoens Kathrin Tintelnot Krzysztof Ulfig Aristea Velegraki Anna Maria Tortorano Sandrine Giraud Sara Mina Kinga Rigler-Hohenwarter Fernando L.Hernando Andoni Ramirez-Garcia Aize Pellon Jashanpreet Kaur Eliana Barreto Bergter Jardel Vieira de Meirelles Ingrid Dutra da Silva Laurence Delhaes Ana Alastruey-Izquerdo Ruo-yu Li Qiaoyun Lu Tarek Moussa Omar Almaghrabi Hassan Al-Zahrani Gen Okada Shuwen Deng Wangqing Liao Jingsi Zeng Jouni Issakainen Livia Cristina Liporagi Lopes 2014Fungal Diversity2014,,4:1
14Fecal marker levels as predictors of need for endoscopic balloon dilation in Crohn's disease patients with anastomotic strictures显示文摘AIM To evaluate the accuracy and best cut-off value of fecal calprotectin(FC) and fecal lactoferrin(FL) to predict disease recurrence in asymptomatic patients presenting with anastomotic strictures. METHODS This was a longitudinal single tertiary center study based on prospectively collected data(recorded in a clinical database created for this purpose) performed between March 2010 and November 2014. Crohn's disease(CD) patients with anastomotic stricture who submitted to postoperative endoscopic evaluation were included. Stools were collected on the day before bowel cleaning for FC and FL. Endoscopic balloon dilation(EBD) was performed if the patient presented an anastomotic stricture not traversed by the colonoscope, regardless of patients' symptoms. Successful dilation was defined as passage of the colonoscope through the dilated stricture into the neotermimal ileum.Postoperative recurrence was defined as a modified Rutgeerts score of ≥ i2 b. RESULTS In a total of 178 patients who underwent colonoscopy, 58 presented an anastomotic stricture, 86% were asymptomatic, and 48(54% male; median age of 46.5 years) were successfully dilated. Immediate success rate was 92% and no complications were recorded. FC and FL levels correlated significantly with endoscopic recurrence(P < 0.001) with an optimal cut-off value of 90.85 μg/g(sensitivity of 95.5%, specificity of 69.2%, positive predictive value(PPV) of 72.4%, negative predictive value(NPV) of 94.7% and accuracy of 81%] for FC and of 5.6 μg/g(sensitivity of 77.3%, specificity of 69.2%, PPV of 68%, NPV of 78.4% and accuracy of 72.9%) for FL.CONCLUSION Fecal markers are good predictors of CD endoscopic recurrence in patients with asymptomatic anastomotic stricture. FC and FL may guide the need for EBD in this context.Susana Lopes Patrícia Andrade Eduardo Rodrigues-Pinto Joana Afonso Guilherme Macedo Fernando Magro 2017World Journal of Gastroenterology2017,23,35:1
