1H pylori (CagA) and Epstein-Barr virus infection in gastric carcinomas:Correlation with p53 mutation and c-Myc,Bcl-2 and Bax expression显示文摘AIM: To investigate the interrelationship between H pylori and Epstein-Barr virus (EBV) infection in the gastric carcinogenesis having in focus the p53 mutation and the c-Myc, Bcl-2 and Bax expression. METHODS: seventy-one gastric carcinoma tissues were assessed by polymerase chain reaction (PCR) for H pylori and in situ hybridization for EBV. c-Myc, Bcl-2 and Bax expression were detected by immunohistochemistry and single-stranded conformational polymorphism (SSCP) for p53 mutation. RESULTS: The positivity rates for H pylori and EBV were 94.4% and 8.45%, respectively. The majority of the cases displayed only the H pylori presence. All EBV positive cases were also H pylori positive. None infectious agent was observed in 5.55% of the cases. The intestinal type tumor was more frequent in the co-infected and non-infected groups. The female predominated in the non-infected group showing statistical significance (70.4% vs 29.6%, P=0.039). The Bcl-2 was only detected in the group exclusively infected by H pylori. However, c-Myc and Bax were detected in the three groups but with a low frequency in the co-infected group. Mutation of p53 was present in all groups, with the highest frequencies in the H pylori positive groups. CONCLUSION: The frequency of H pylori infection in gastric carcinomas was high. The presented data indicated that gastric carcinogenesis has different pathways depending of the presence of the two investigated infectious agents, suggesting a possible involvement of H pylori with apoptotic process. The low expression of c-Myc and Bax in the EBV-positive groups suggests that EBV may inhibit the expression of these proteins. Nevertheless, p53 mutation shows to be a relevant alteration, independent of both infectious agents.Valeska Portela Lima Marcos Antonio Pereira de Lima Angela Rosa André Márcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Sílvia Helena Barem Rabenhorst 2008World Journal of Gastroenterology2008,14,6:17
2一种面向边缘计算的高效异步联邦学习机制显示文摘随着物联网和移动设备性能的不断提高,一种新型计算架构——边缘计算——应运而生.边缘计算的出现改变了数据需要集中上传到云端进行处理的局面,最大化利用边缘物联网设备的计算和存储能力.边缘计算节点对本地数据进行处理,不再需要把大量的本地数据上传到云端进行处理,减少了数据传输的延时.在边缘网络设备上进行人工智能运算的需求也在逐日增大,因为联邦学习机制不需要把数据集中后进行模型训练,所以更适合于节点平均数据量有限的边缘网络机器学习的场景.针对以上挑战,提出了一种面向边缘网络计算的高效异步联邦学习机制(efficient asynchronous federated learning mechanism for edge network computing,EAFLM),根据自适应的阈值对训练过程中节点与参数服务器之间的冗余通信进行压缩.其中,双重权重修正的梯度更新算法,允许节点在学习的任何过程中加入或退出联邦学习.实验显示提出的方法将梯度通信压缩至原通信次数的8.77%时,准确率仅降低0.03%.芦效峰 廖钰盈 Pietro Lio Pan Hui 2020计算机研究与发展2020,57,12:16

4Research advances on the multiple uses of Moringa oleifera: a sustainable alternative for socially neglected population显示文摘Moringa oleifera Lam(Moringaceae) is a plant with high nutritional and medicinal value. Native to India, it is now widely distributed throughout tropical and subtropical regions of the world. Its different parts are sources of proteins, vitamins and minerals and present different pharmacological and biotechnological potential. Moreover, M. oleifera seeds are widely used in water and effluent treatment, for their coagulation, flocculation and sedimentation properties, their ability of improving water quality, by reducing organic matter and microbial load, with special applicability in intensive animal production systems, such as aquaculture. In addition, due to its high nutritional value and several medicinal properties, this tree may act as a nutritional and medical alternative for socially neglected populations. In this context, this review gathers information on M. oleifera, emphasizing its chemical constituents, nutritional, pharmacological and antimicrobial properties, applications in the treatment of water effluents, and ecological and social aspects.Raimunda Samia Nogueira Brilhante Jamille Alencar Sales Vandbergue Santos Pereira Débora de Souza Collares Maia Castelo-Branco Rossana de Aguiar Cordeiro Célia Maria de Souza Sampaio Manoel de Araújo Neto Paiva Joao Bosco Feitosa dos Santos JoséJúlio CostaSidrim Marcos Fábio Gadelha Rocha 2017Asian Pacific Journal of Tropical Medicine2017,10,7:10
5Relationship between vascular endothelium and periodontal disease in atherosclerotic lesions: Review article显示文摘Inflammation and endothelial dysfunction are linked to the pathogenesis of atherosclerotic disease. Recent studies suggest that periodontal infection and the ensuing increase in the levels of inflammatory markers may be associated with myocardial infarction, peripheral vascular disease and cerebrovascular disease. The present article aimed at reviewing contemporary data on the pathophysiology of vascular endothelium and its association with periodontitis in the scenario of cardiovascular disease.Marco Aurélio Lumertz Saffi Mariana Vargas Furtado Carisi Anne Polanczyk Márlon Munhoz Montenegro Ingrid Webb Josephson Ribeiro Cassio Kampits Alex Nogueira Haas Cassiano Kuchenbecker Rosing Eneida Rejane Rabelo-Silva 2015World Journal of Cardiology2015,7,1:9
6Growth mechanism of octahedron-like BaMoO_4 microcrystals processed in microwave-hydrothermal:Experimental observations and computational modeling显示文摘Octahedron-like BaMoO4 microcrystals were synthesized by the co-precipitation method at room temperature and processed in microwave-hydrothermal at 413 K for different times (from 30 min to 5 h). These microcrystals were analyzed by X-ray diffraction (XRD),field-emission gun scanning electron microscopy (FEG-SEM) and transmission electron microscopy (TEM). XRD patterns showed that this material presents a tetragonal structure without the presence of deleterious phases. FEG-SEM and TEM micrographs revealed that the BaMoO4 microcrystals present an octahedron-like morphology with agglomerate nature and poly-disperse particle size distribution. These micrographs also indicated that the microcrystals grow along the [0 0 1] direction. The observed crystallographic planes in these structures were modeled computationally and a crystal growth model was proposed in order to explain the morphological changes as a function of processing time.Laécio Santos Cavalcante Júlio César Sczancoski Rircado Luis Tranquilin José Arana Varela Elson Longo Marcelo Ornaghi Orlandi 2009Particuology2009,7,5:9
7Acute effects of physical exercise in type 2 diabetes: A review显示文摘The literature has shown the efficiency of exercise in the control of type 2 diabetes(T2D), being suggested as one of the best kinds of non-pharmacological treatments for its population. Thus, the scientific production related to this phenomenon has growing exponentially. However, despite its advances, still there is a lack of studies that have carried out a review on the acute effects of physical exercise on metabolic and hemodynamic markers and possible control mechanisms of these indicators in individuals with T2 D, not to mention that in a related way, these themes have been very little studied today. Therefore, the aim of this study was to organize and analyze the current scientific production about the acute effects of physical exercise on metabolic and hemodynamic markers and possible control mechanisms of these indicators in T2 D individuals. For such, a research with the following keywords was performed:-exercise; diabetes and post-exercise hypotension; diabetes and excess post-exercise oxygen consumption; diabetes and acute effects in PUBMED, SCIELO and HIGHWIRE databases. From the analyzed studies, it is possible to conclude that, a single exercise session can promote an increase in the bioavailability of nitric oxide and elicit decreases in postexercise blood pressure. Furthermore, the metabolic stress from physical exercise can increase the oxidation of carbohydrate during the exercise and keep it, in high levels, the post exercise consumption of O2, this phenomenon increases the rate of fat oxidation during recovery periods after exercise, improves glucose tolerance and insulin sensitivity and reduces glycemia between 2-72 h, which seems to be dependent on the exercise intensity and duration of the effort.Ricardo Yukio Asano Marcelo Magalhes Sales Rodrigo Alberto Vieira Browne José Fernando Vila Nova Moraes Hélio José Coelho Júnior Milton Rocha Moraes Hebert Gustavo Simoes 2014World Journal of Diabetes2014,5,5:8
8“四证合一”培养模式下的分年级专业学位硕士研究生临床胜任力自评分析显示文摘目的 在“四证合一”并轨培养模式下,评估不同年级专业学位硕士研究生达到相应年级住院医师临床胜任力水平的情况.方法 选择武汉大学人民医院全部“四证合一”并轨培养模式下的272名专业学位硕士研究生为本研究对象,采用问卷调查方法对其进行相关调查.问卷所涉及的临床胜任力结构包含5个维度和15个项目.按照住院医师临床胜任力标准,将每个项目分为3个年级能力层次,并与住院医师规范化培训的结业标准进行匹配.根据专业学位硕士研究生自评水平是否达到相应标准计算达标情况,包含整体达标率、维度达标率和项目达标比例3个层面.结果 临床胜任力分年级标准比结业标准更能够有效区分不同年级专业学位硕士研究生的能力水平.临床胜任力分年级标准的达标情况表现出研究生年级越高、相应能力层次的达标率越低的变化.在三年级研究生的自评中,虽然结业标准达标情况较好,但临床胜任力分年级标准达标情况却较差.结论 在并轨培养模式下,虽然“四证合一”专业学位硕士研究生能够达到住院医师规范化培训的结业标准,但尚不能达到其临床胜任力标准.因此,在住院医师规范化培训中,不仅要完成国家标准的培训时长、项目和数量,还要有效监测和提升不同年级研究生的临床胜任力水平.卢章洪 林青 Jonathan Lio 金松 2017中华医学教育杂志2017,37,6:7

11Helicobacter pylori and EBV in gastric carcinomas:Methylation status and microsatellite instability显示文摘AIM:To verify the methylation status of CDH1, DAPK, COX2, hMLH1 and CDKN2A genes and to evaluate their association with Helicobacter pylori (H. pylori)-cagA+ and Epstein Barr virus (EBV) infections in gastric adenocarcinomas.METHODS: Methylation-specific PCR (MSP) assay was performed in 89 primary gastric carcinomas (intestinal and diffuse types). Microsatellite instability (MSI) analysis was performed using the BAT26 primer set and PCR products were analyzed with the ABI PRISM 3100 Genetic Analyzer using Genescan 3.7 software (Applied Biosystems). Detection of H. pylori and genotyping were performed by PCR, using specifi c primers for ureaseC and cagA genes. The presence of EBV was assessed by in situ hybridization. Statistical analyses were performed using the χ2 or Fisher's exact test.RESULTS: The most frequent hypermethylated gene was COX-2 (63.5%) followed by DAPK (55.7%), CDH1 (51%), CDKN2A (36%) and hMLH1 (30.3%). Intestinal and diffuse adenocarcinomas showed different methylation profiles and there was an association between methylation of E-CDH1 and H. pylori-cagA+ in the intestinal adenocarcinoma type. MSI was correlated with hMLH1 methylation. There was an inverse correlation between DAPK hypermethylation and MSI.CONCLUSION: We found a strong association between CDH1 methylation and H. pylori-cagA+ in intestinal-type gastric cancer, association of MSI and better prognosis and an heterogeneous COX-2 overexpression.Adriana Camargo Ferrasi Nídia Alice Pinheiro Silvia Helena Barem Rabenhorst Otávia Luisa Caballero Maria Aparecida Marchesan Rodrigues Fabrício de Carvalho Celso Vieira de Souza Leite Marcia Valéria Pitombeira Ferreira Marcos Aurélio Pessoa Barros Maria Inês de Moura Campos Pardini 2010World Journal of Gastroenterology2010,16,3:6
12Embolization of splenorenal shunt associated to portal vein thrombosis and hepatic encephalopathy显示文摘Hepatic encephalopathy(HE)is a cognitive disturbance characterized by neuropsychiatric alterations.It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts.The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration.Therefore,the embolization of these shunts has been performed tocontrol HE manifestations,but the presence of portal vein thrombosis is considered a contraindication.In this presentation we show a cirrhotic patient with severe HE and portal vein thrombosis who was submitted to embolization of a large portosystemic shunt.Case report:a 57 years-old cirrhotic patient who had been hospitalized many times for persistent HE and hepatic coma,even without precipitant factors.She had a wide portosystemic shunt and also portal vein thrombosis.The abdominal angiography confirmed the splenorenal shunt and showed other shunts.The larger shunt was embolized through placement of microcoils,and the patient had no recurrence of overt HE.There was a little increase of esophageal and gastric varices,but no endoscopic treatment was needed.Since portosystemic shunts are frequent causes of recurrent HE in cirrhotic patients,portal vein thrombosis should be considered a relative contraindication to perform a shunt embolization.However,in particular cases with many shunts and severe HE,we found that one of these shunts can be safely embolized and this procedure can be sufficient to obtain a good HE recovery.In conclusion,we reported a case of persistent HE due to a wide portosystemic shunt associated with portal vein thrombosis.As the patient had other shunts,she was successfully treated by embolization of the larger shunt.Letícia de Campos Franzoni Fábio Cardoso de Carvalho Rafael Gomes de Almeida Garzon Fábio da Silva Yamashiro Laís Augusti Lívia Alves Amaral Santos Mariana de Souza Dorna Júlio Pinheiro Baima Talles Bazeia Lima Carlos Antonio Caramori Giovanni Faria Silva Fernando Gomes Romeiro 2014World Journal of Gastroenterology2014,20,42:6
13Relationship 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
14Benefit of stem cells and skeletal myoblast cells in dilated cardiomyopathies显示文摘Although some authors suggest that there is mitotic division in the heart,most cardiomyocytes do not have the capacity to regenerate after myocardial infarction and when this occurs there is a deterioration of contractile function,and if the area of infarction is extensive ventricular remodeling may occur,leading to the development of heart failure.Cell transplantation into the myocardium with the goal of recovery of cardiac function has been extensively studied in recent years. The effects of cell therapy are based directly on the cell type used and the type of cardiac pathology.For myocardial ischemia in the hibernating myocardium, bone marrow cells have functional benefits,however these results in transmural fibrosis are not evident. In these cases there is a benefit of implantation with skeletal myoblasts,for treating the underlying cause of disease,the loss of cell contractility.Luiz César Guarita-Souza Júlio César Francisco Rossana Simeoni Jose Rocha Faria-Neto Katherine Athayde Teixeira de Carvalho 2011World Journal of Cardiology2011,3,3:4
15In vitro morphogenic response of leaf sheath of Phyllostachys bambusoides显示文摘Nodal segments from secondary branches of saplings of Phyllostachys bambusoides were inoculated in MS medium to assess the in vitro morphogenic response of leaf sheath through the induction to callogenesis by Picloram(4-amino-3,5,6-trichloropicolinic acid) at different concentrations of carbohydrate under the same conditions with presence or absence of luminosity.In our experiment,secondary explants were kept in MS medium containing 8.0 mg·L-1 of Picloram for the callus formation.Calluses were transferred in MS medium supplemented with sucrose,fructose and glucose(control,2%,4% and 6%).Results show that Picloram induced the callogenesis in leaf sheath.The secondary embryogenesis was formed in yellow-globular callus.The sucrose as carbohydrate source in the absence of light was more efficient to induce rhizogenesis.Glucose was more efficiency in the presence of light.Callogenic induction and further embryogenesis evidenced the competence and determination of leaf sheath cells.Yurika H.Komatsu Katherine Derlene Batagin-Piotto Gilvano Ebling Brondani Antnio Natal Gonalves Marcílio de Almeida 2011Journal of Forestry Research2011,22,2:3

17Menopause and cognitive impairment:A narrative review of current knowledge显示文摘A severe impairment of cognitive function characterizes dementia.Mild cognitive impairment represents a transition between normal cognition and dementia.The frequency of cognitive changes is higher in women than in men.Based on this fact,hormonal factors likely contribute to cognitive decline.In this sense,cognitive complaints are more common near menopause,a phase marked by a decrease in hormone levels,especially estrogen.Additionally,a tendency toward worsened cognitive performance has been reported in women during menopause.Vasomotor symptoms(hot flashes,sweating,and dizziness),vaginal dryness,irritability and forgetfulness are common and associated with a progressive decrease in ovarian function and a subsequent reduction in the serum estrogen concentration.Hormone therapy(HT),based on estrogen with or without progestogen,is the treatment of choice to relieve menopausal symptoms.The studies conducted to date have reported conflicting results regarding the effects of HT on cognition.This article reviews the main aspects of menopause and cognition,including the neuroprotective role of estrogen and the relationship between menopausal symptoms and cognitive function.We present and discuss the findings of the central observational and interventional studies on HT and cognition.Délio Marques Conde Roberto Carmignani Verdade Ana L R Valadares Lucas F B Mella Adriana OrcesiPedro Lucia Costa-Paiva 2021World Journal of Psychiatry2021,11,8:3
18Bile duct hamartomas-the von Meyenburg complex显示文摘ABSTRACT: Hamartomas of the bile duct (von Meyenburg complex) are benign neoplasms of the liver, constituted histologically cystic dilatations of the bile duct, encompassed by fibrous stroma. We report a 42-year-old female patient with symptomatic cholecystitis, whose gross and ultrasonic appearance suggestive of multiple liver metastases. Magnetic resonance imaging and liver biopsy are the gold standards for diagnosis of this rare hepatobiliary condition.Valdemir José Alegre Salles Alexandre Marotta Jorge Miguel Kather Netto Manlio Basílio Speranzini Marcos Roberto Martins 2007Hepatobiliary & Pancreatic Diseases International2007,6,1:3
19Low-level laser therapy enhances the number of osteocytes in calvaria bone defects of ovariectomized rats显示文摘Background : Osteoporosis can make bone repair difficult. Low-level laser therapy( LLLT) has been shown to be a promising tool for bone neoformation. This study aimed to analyze the effect of LLLT on calvaria bone defects of ovariectomized rats using stereology. Methods : Fifty-four Wistar rats were subjected to bilateral ovariectomy, and bone defects were created in calvaria after 150 days. The animals were divided into nine groups(n = ?6 per group), and 24 hours after the bone defects were created they received three, six or 12 sessions of LLLT at 0, 20 or 30 J/cm 2, using a 780-nm low-intensity GaAlAs laser. One-way ANOVA followed by Tukey ' s post hoc test was used for data processing. A difference of P < 0.05 was considered statistically significant. The parameters evaluated were osteocyte density( Nv_(ost)), total osteocyte number( Nto ost), trabecular surface density( Sv_t), and trabecular surface area( Sa_t). Results : Data obtained showed that Nto ost, Sv t, and Sa t in group G2 rats were significantly different from G1(0 J/cm^2)( P < 0.05). Compared to group G4, G5 presented higher values for the parameters Sv t and Sa t, and G6 presented significantly higher values for almost all the analyzed parameters( Nv _(ost), Nto_(ost), Sv_t, and Sa t)( P < 0.05). Compared to group G7, G8 showed a higher value only for the parameter Sa t, and G9 showed significantly higher values for parameters Nv ost, Nto ost, Sv_t, and Sa_t. Conclusion : We conclude that LLLT stimulated bone neoformation and contributed to an increase in the total number of osteocytes, especially with a laser energy density of 30 J/cm^2 given for six and 12 sessions.Priscilla Hakime Scalize Luiz Gustavo de Sousa Lígia Maria Napolitano Goncalves Dimitrius Leonardo Pitol Marcelo Palinkas Antonio Augusto Coppi Mariah Acioli Righeti Vitória Ricardo Karina Fittipaldi Bombonato-Prado Simone Cecílio Hallak Regalo Selma Siessere 2019Animal Models and Experimental Medicine2019,2,1:2
20Oral refeeding in mild acute pancreatitis:An old challenge显示文摘Although the idea that pancreas rest has long been considered as a very relevant topic in acute pancreatitis (AP)therapy,the right time and type of diet to be offered to patients recovering from an acute attack are a great challenge to clinicians who treat this condition.Fortunately,the last decade was noted for several trials looking for the best answer to the question:'when and how to start oral refeeding in AP?'It is well known that 80%of patients present with mild disease characterized by usually uncomplicated clinical course are managed with pancreatic rest through nil per oral;while the use of specific nutritional intervention is an exception.Therefore,mild AP has been the most investigated form of AP and researchers have tried different kind of meals to offer calories and reduce costs by shortening hospitalization time.Usually in mild AP,the oral refeeding is introduced between the first 3 d and 7 d after hospitalization but,the type of diet and patients’tolerance have been scrutinized in detail with mixed results.Although 20%to 25%have pain recurrence requiring nutritional support and greater time of hospitalization,most patients seem to tolerate oral refeeding well.We propose analyzing the most recent investigations of this matter and their conclusions to develop a better understanding of the management of AP.Júlio Maria F Chebli Pedro D Gaburri Liliana A Chebli 2011World Journal of Gastrointestinal Pathophysiology2011,2,6:2
