1Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets.Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,10:5
2Pancreatitis after endoscopic retrograde cholangiopancreatography:A narrative review显示文摘Acute post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP)is a feared and potentially fatal complication that can be as high as up to 30%in high-risk patients.Pre-examination measures,during the examination and after the examination are the key to technical and clinical success with a decrease in adverse events.Several studies have debated on the subject,however,numerous topics remain controversial,such as the effectiveness of prophylactic medications and the amylase dosage time.This review was designed to provide an update on the current scientific evidence regarding PEP available in the literature.Igor Braga Ribeiro Epifanio Silvino do Monte Junior Antonio Afonso Miranda Neto Igor Mendonça Proença Diogo Turiani Hourneaux de Moura Mauricio Kazuyoshi Minata Edson Ide Marcos Eduardo Lera dos Santos Gustavo de Oliveira Luz Sergio Eiji Matuguma Spencer Cheng Renato Baracat Eduardo Guimarães Hourneaux de Moura 2021World Journal of Gastroenterology2021,27,20:5
3Prognostic significance of vascular endothelial growth factor polymorphisms in colorectal cancer patients显示文摘AIM To investigate the associations of the genetic polymor-phisms of vascular endothelial growth factor A(VEGF-A)-1498C>T and-634G>C, with the survival of patients with colorectal cancer(CRC). METHODS A prospective cohort consisting of 131 Brazilians patients consecutively operated on with a curative intention as a result of sporadic colorectal carcinoma was studied. DNA was extracted from peripheral blood and its amplification and allelic discrimination for each genetic polymorphism was performed using the technique of polymerase chain reaction(PCR) in real-time. The real-time PCR technique was used to identify the VEGF-A-1498C>T(rs833031) and-634G>C(rs2010963) polymorphisms. Genotyping was validated for VEGF-A-1498C>T polymorphism in 129 patients and for VEGF-A-634G>C polymorphism in 118 patients. The analysis of association between categorical variables was performed using logistic regression, survival by Kaplan-Meier method and multivariate analysis by the Cox regression method. RESULTS In the univariate analysis there was a significant association(OR = 0.32; P = 0.048) between genotype CC of the VEGF-A-1498C>T polymorphism and the presence of CRC liver metastasis. There was no association between VEGF-A-1498C>T polymorphism and VEGF-A-634G>C polymorphism with further clinical or anatomopathologic variables. The genotype CC of the VEGF-A-1498C>T polymorphism was significantly correlated with the 5-year survival(P = 0.032), but not significant difference(P = 0.27) was obtained with the VEGF-A-634G>C polymorphism with the 5-year survival in the univariate analysis. The genotype CT(HR = 2.79) and CC(HR = 4.67) of the polymorphism VEGF-A-1498C>T and the genotype CC(HR = 3.76) of the polymorphism VEGF-A-634C>G acted as an independent prognostic factor for the risk of death in CRC patients. CONCLUSION The CT and CC genotypes of the VEGF-A-1498C>T and the CC genotype of the VEGF-A-634C>G polymorphisms are prognostic factors of survival in Brazilians patients with sporadic colorectal carcinoma.Gilmar Ferreira do Espírito Santo Bianca Borsatto Galera Elisabeth Carmen Duarte Elisabeth Suchi Chen Lenuce Azis Amilcar Sabino Damazo Gabriela Tognini Saba Flávia de Sousa Gehrke Ismael Dale Cotrim Guerreiro da Silva Jaques Waisberg 2017World Journal of Gastrointestinal Oncology2017,9,2:4
4Methane production and small intestinal bacterial overgrowth in children living in a slum显示文摘AIM:To analyze small intestinal bacterial overgrowth in school-aged children and the relationship between hydrogen and methane production in breath tests.METHODS:This transversal study included 85 children residing in a slum and 43 children from a private school,all aged between 6 and 10 years,in Osasco,Brazil.For characterization of the groups,data regarding the socioeconomic status and basic housing sanitary conditions were collected.Anthropometric data was obtained in children from both groups.All children completed the hydrogen(H 2) and methane(CH 4) breath test in order to assess small intestinal bacterial overgrowth(SIBO).SIBO was diagnosed when there was an increase in H 2 ≥ 20 ppm or CH 4 ≥ 10 ppm with regard to the fasting value until 60 min after lactulose ingestion.RESULTS:Children from the slum group had worse living conditions and lower nutritional indices than children from the private school.SIBO was found in 30.9%(26/84) of the children from the slum group and in 2.4%(1/41) from the private school group(P = 0.0007).Greater hydrogen production in the small intestine was observed in children from the slum group when compared to children from the private school(P = 0.007).A higher concentration of hydrogen in the small intestine(P < 0.001) and in the colon(P < 0.001) was observed among the children from the slum group with SIBO when compared to children from the slum group without SIBO.Methane production was observed in 63.1%(53/84) of the children from the slum group and in 19.5%(8/41) of the children from the private school group(P < 0.0001).Methane production was observed in 38/58(65.5%) of the children without SIBO and in 15/26(57.7%) of the children with SIBO from the slum.Colonic production of hydrogen was lower in methaneproducing children(P = 0.017).CONCLUSION:Children who live in inadequate environmental conditions are at risk of bacterial overgrowth and methane production.Hydrogen is a substrate for methane production in the colon.Carolina Santos Mello Soraia Tahan Lígia Cristina FL Melli Mirian Silva do Carmo Rodrigues Ricardo Martin Pereira de Mello Isabel Cristina Affonso Scaletsky Mauro Batista de Morais 2012World Journal of Gastroenterology2012,18,41:3
5Role of pancreatography in the endoscopic management of encapsulated pancreatic collections-review and new proposed classification显示文摘Pancreatic fluids collections are local complications related to acute or chronic pancreatitis and may require intervention when symptomatic and/or complicated.Within the last decade,endoscopic management of these collections via endoscopic ultrasound-guided transmural drainage has become the gold standard treatment for encapsulated pancreatic collections with high clinical success and lower morbidity compared to traditional surgery and percutaneous drainage.Proper understanding of anatomic landmarks,including assessment of the main pancreatic duct and any associated lesions–such as disruptions and strictures-are key to achieving clinical success,reducing the need for reintervention or recurrence,especially in cases with suspected disconnected pancreatic duct syndrome.Additionally,proper review of imaging and anatomic landmarks,including collection location,are pivotal to determine type and size of pancreatic stenting as well as approach using long-term transmural indwelling plastic stents.Pancreatography to adequately assess the main pancreatic duct may be performed by two methods:Either non-invasively using magnetic resonance cholangiopancreatography or endoscopically via retrograde cholangiopancreatography.Despite the critical need to understand anatomy via pancrea tography and assess the main pancreatic duct,a standardized approach or uniform assessment strategy has not been described in the literature.Therefore,the aim of this review was to clarify the role of pancreatography in the endoscopic management of encapsulated pancreatic collections and to propose a new classification system to aid in proper assessment and endoscopic treatment.Igor Mendonca Proença Marcos Eduardo Lera dos Santos Diogo Turiani Hourneaux de Moura Igor Braga Ribeiro Sergio Eiji Matuguma Spencer Cheng Thomas R McCarty Epifanio Silvino do Monte Junior Paulo Sakai Eduardo Guimaraes Hourneaux de Moura 2020World Journal of Gastroenterology2020,26,45:3
6Influence of Sugarcane Bagasse Fiber Size on Biodegradable Composites of Thermoplastic Starch显示文摘Although thermoplastic starch(TPS)is biodegradable,its low mechanical resistance limits its wide application.Sugarcane bagasse(SB)fibers can be used as reinforcement in TPS matrix composites,but the influence of fiber size on the properties of the composite is still unknown.In this study,TPS composites reinforced with SB short fibers of four sizes were processed and characterized in order to analyze the influence of fiber size on the mechanical properties of the TPS/SB composite.It was observed that the interaction between fiber and matrix was good and optimized when the fibers are sifted in sieves between 30 and 50 mesh,obtaining fibers with average length of 1569±640μm and average diameter of 646±166μm.For these composites,increases of more than 660%in the modulus and more than 100%in the maximum tension were verified when compared to the pure TPS.Bruno Henrique dos Santos Karen de Souza do Prado Asaph Armando Jacinto Marcia Aparecida da Silva Spinace 2018Journal of Renewable Materials2018,6,2:2

8Chemical and microbiological characterization of tinctures and microcapsules loaded with Brazilian red propolis extract显示文摘The aim of this study was to characterize tinctures and microcapsules loaded with an ethanol extract of red propolis through chemical, physicochemical and microbiological assays in order to establish quality control tools for nutraceutical preparations of red propolis. The markers(isoflavonoids, chalcones, pterocarpans,flavones, phenolic acids, terpenes and guttiferones) present in the tinctures A and B were identified and confirmed using LC/ESI/FTMS/Orbitrap. Four compositions(A, B, C and D) were prepared to contain B tincture of the red propolis with some pharmaceutical excipients and submitted to two drying processes, i. e.spray-drying and freeze-drying to obtain microcapsules loaded with the red propolis extract. The tinctures and microcapsules of the red propolis were submitted to the total flavonoid content and antioxidant activity tests.The antibacterial activity and minimum inhibitory concentration(MIC) were tested using Staphylococcus aureus ATCC 25293 and Pseudomonas aeruginosa ATCC 27853 strains. The tinctures and microcapsules presented high flavonoid quantities from 20.50 to 40.79 mg/100 mg of the microcapsules. The antioxidant activity and IC50 were determined for the tinctures A and B(IC50: 6.95 μg/m L and 7.48 μg/m L), the spray-dried microcapsules(IC50: 8.89–15.63 μg/m L) and the freeze-dried microcapsules(IC50: 11.83–23.36 μg/m L). The tinctures and microcapsules were proved to be bioactive against gram-positive and gram-negative bacteria with inhibition halos superior to 10 mm at concentration of 200 μg/m L and MIC values of 135.87–271.74 μg/m L using gram-positive strain and 271.74–543.48 μg/m L using gram-negative strain. The tinctures and microcapsules of the red propolis have a potential application for nutraceutical products.Erika Tayse da Cruz Almeida Maria Cristina Delgado da Silva José Marcos dos Santos Oliveira Regianne Umeko Kamiya Rodolfo Elleson dos Santos Arruda Danilo Abreu Vieira Valdemir da Costa Silva Pierre Barnabé Escodro Irinaldo Diniz Basílio-Júnior Ticiano Gomes do Nascimento 2017Journal of Pharmaceutical Analysis2017,7,5:2

12Effects of blood flow restriction without additional exercise on strength reductions and muscular atrophy following immobilization:A systematic review显示文摘Purpose:To investigate whether blood flow restriction(BFR) without concomitant exercise mitigated strength reduction and atrophy of thigh muscles in subjects under immobilization for lower limbs.Methods:The following databases were searched:PubMed,CINAHL,PEDro,Web of Science,Central,and Scopus.Results:The search identified 3 eligible studies,and the total sample in the identified studies consisted of 38 participants.Isokinetic and isometric torque of the knee flexors and extensors was examined in 2 studies.Cross-sectional area of thigh muscles was evaluated in 1 study,and thigh girth was measured in 2 studies.The BFR protocol was 5 sets of 5 min of occlusion and 3 min of free flow,twice daily for approximately 2 weeks.As a whole,the included studies indicate that BFR without exercise is able to minimize strength reduction and muscular atrophy after immobilization.It is crucial to emphasize,however,that the included studies showed a high risk of bias,especially regarding allocation concealment,blinding of outcome assessment,intention-to-treat analyses,and group similarity at baseline.Conclusion:Although potentially useful,the high risk of bias presented by original stodies limits the indication of BFR without concomitant exercise as an effective countermeasure against strength reduction and atrophy mediated by immobilization.Mikhail Santos Cerqueira Jose Diego Sales Do Nascimento Daniel Germano Maciel Jean Artur Mendonca Barboza Wouber Herickson De Brito Vieira 2020Journal of Sport and Health Science2020,9,2:1
