| 1 | Quantitative Study on Nonmetallic Inclusion Particles in Steels by Automatic Image Analysis With Extreme Values Method显示文摘The presence of nonmetallic inclusion particles which appear during steelmaking process is harmful to the properties of steels,which is mainly as a function of some aspects such as size,volume fraction,shape,and distribution of these particles.The automatic image analysis technique is one of the most important tools for the quantitative determination of these parameters.The classical Student approach and the Extreme Values Method(EVM) were used for the inclusion size and shape determination and the evaluation of distance between the inclusion particles.The results thus obtained indicated that there were significant differences in the characteristics of the inclusion particles in the analyzed products.Both methods achieved results with some differences,indicating that EVM could be used as a faster and more reliable statistical methodology. | Cássio Barbosa José Brant de Campos Jneo Lopes do Nascimento Iêda Maria Vieira Caminha | 2009 | Journal of Iron and Steel Research(International)2009,16,4: | 7 |
| 2 | Relationship 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 | 2021 | World Journal of Clinical Oncology2021,12,10: | 5 |
| 3 | Slope Processes, Mass Movement and Soil Erosion: A Review显示文摘Soil erosion and land degradation are global problems and pose major issues in many countries.Both soil erosion and mass movement are two forms of land degradation and humans play important roles in these geomorphological processes.This paper reviews slope processes associated with mass movement and soil erosion and contributory factors,including physical and human agents.Acting together,these cause diverse geomorphological features.Slope processes are illustrated by reference to case studies from Brazil and UK.The causes and impacts of erosion are discussed,along with appropriate remedial bioengineering methods and the potential of the measures to prevent these types of environmental degradation.Although there are several agents of erosion,water is the most important one.Cultivation can promote soil erosion,due to ploughing and harvesting,which moves soil down slopes.Soil erosion and mass movement data would inform the viability of soil conservation practices.Integrated management of drainage basins offers a promising way forward for effective soil conservation and soil remedial bioengineering in Brazil and UK. | Antonio Jos Teixeira GUERRA Michael Augustine FULLEN Maria do Carmo Oliveira JORGE Joss Fernando Rodrigues BEZERRA Mohamed S.

| 4 | Irreversible electroporation for the management of pancreatic cancer: Current data and future directions显示文摘Pancreatic cancer is currently the seventh leading cause of cancer death(4.5%of all cancer deaths)while 80%-90%of the patients suffer from unresectable disease at the time of diagnosis.Prognosis remains poor,with a mean survival up to 15 mo following systemic chemotherapy.Loco-regional thermal ablative techniques are rarely implemented due to the increased risk of thermal injury to the adjacent structures,which can lead to severe adverse events.Irreversible electroporation,a promising novel non-thermal ablative modality,has been recently introduced in clinical practice for the management of inoperable pancreatic cancer as a safer and more effective loco-regional treatment option.Experimental and initial clinical data are optimistic.This review will focus on the basic principles of IRE technology,currently available data,and future directions. | Stavros Spiliopoulos Lazaros Reppas Dimitrios Filippiadis Antonella Delvecchio Maria Conticchio Riccar do Memeo Riccardo Inchingolo | 2023 | World Journal of Gastroenterology2023,29,2: | 3 |

| 6 | Adenocarcinoma of the third and fourth portions of the duodenum: The capsule endoscopy value显示文摘Primary adenocarcinoma of the small intestine occurs in over 50% of cases in the duodenum. However,its location in the third and fourth duodenal portions occurs rarely and is a diagnostic challenge. The aim of this work is to report an adenocarcinoma of the third and fourth duodenal portions,emphasizing its diagnostic difficulty and the value of video capsule endoscopy. A man,40 years old,with no medical history,with abdominal discomfort and progressive fatigue,presented four months ago with one episode o f m o d e ra t e m e l e n a. T h e p hy s i c a l e x a m i n a t i o n was normal,except for mucosal pallor. Blood tests were consistent with microcytic,hypochromic iron deficiency anemia with 7.8 g/d L hemoglobin. The upper and lower endoscopy were normal. Additional work-up with video capsule endoscopy showed a polypoid lesion involving the third and fourth portions o f t h e d u o d e n u m. B i o p s y s h o w e d a m o d e ra t e l y differentiated adenocarcinoma. Abdominal computed tomography showed a wall thickening from the third duodenal portion to the proximal jejunum,without distant metastasis. The patient underwent segmental resection(distal duodenum and proximal jejunum) with duodenojejunostomy. The surgical specimen histology confirmed the biopsy diagnosis,with transmural infiltration,without nodal involvement. Conclusion: Adenocarcinoma of the third and fourth portions of the duodenum is difficult to diagnose and capsule endoscopy is of great value. | Feliciano Chanana Paquissi Ana Henriqueta Filipe Bunga Pimentel Lima Maria de Fátima do Nascimento Vieira Lopes Francisco Viamontes Diaz | 2015 | World Journal of Gastroenterology2015,21,31: | 2 |
| 7 | Epidemiology of upper gastrointestinal symptoms in Brazil(Epi Gastro):A population-based study according to sex and age group显示文摘AIM:To determine the prevalences of symptoms consistent with gastroesophageal reflux disease(GERD)and dyspepsia in South America.METHODS:A telephone survey was conducted among adult owners of land-based telephones in S?o Paulo,Brazil,using previously validated computer-assisted sampling and survey protocols.The Portugueselanguage survey included(1)sociodemographic characteristics(e.g.,weight,height,smoking)and comorbidities;(2)dietary habits;(3)presence of symptoms consistent with GERD or dyspepsia within the prior 3mo;and(4)use of medications and other therapies to manage symptoms.Data were stratified post-hoc into three homogeneous geographical regions of S?o Paulo according to the Social Exclusion Indices of the districts and postal codes.Survey response data from each respondent were weighted by the numbers of adults and landline telephones in each household.The analyses were weighted to account for sampling design and to be representative of the S?o Paulo population according to city census data.RESULTS:Among 4570 households contacted,an adult from 3050(66.7%)agreed to participate.The nonresponse rate was 33.3%.The mean(SE)respondent age was 42.6(16.0)years.More than half of all respondents were women(53.1%),aged 18 through 49 years(66.7%),married or cohabitating(52.5%),and/or above normal-weight standards(i.e.,35.3%overweight and 16.3%obese).A total of 26.5%of women were perimenopausal.More than 20%of respondents reported highly frequent symptoms consistent with GERD(e.g.,gastric burning sensation=20.8%)or dyspepsia(e.g.,abdominal swelling/distension=20.9%)at least once per month.Prevalences of these symptoms were significantly(approximately 1.5-to 2.0-fold)higher among women than men but did not vary significantly as a function of advancing age.For instance,14.1%of women reported that they experienced stomach burning(symptom of GERD)at least twice per week,compared to 8.4%of men(P=0.012 byχ2 test).A total of 15.7%of women reported that they experienced abdominal swelling(symptom of dyspepsia)at least twice per week,compared to 6.4%of men(P<0.001byχ2 test).Despite frequent manifestations of GERD or dyspepsia,most(≥90%)respondents reported that they neither received prescription medications fromphysicians,nor took behavioral measures(e.g.,dietary modifications),to manage symptoms.CONCLUSION:Symptoms consistent with dyspepsia and GERD are prevalent in Brazil and represent major public-health and clinical challenges. | Maria do Rosário Dias de Oliveira Latorre Aline Medeiros da Silva Décio Chinzon Jaime N Eisig Telma RP Dias-Bastos | 2014 | World Journal of Gastroenterology2014,20,46: | 2 |

| 10 | Chemical 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 | 2017 | Journal of Pharmaceutical Analysis2017,7,5: | 2 |
