1Species Concepts as Applied to the Whitefly Bemisia tabaci Systematics:How Many Species Are There?显示文摘The worldwide distribution and extensive genetic diversity of the whitefly,Bemisia tabaci,has long been recognized.However,the levels of separation within B.tabaci and the nomenclature of the various genetic groups have been a subject of debate.Recent phylogenetic analyses indicate that B.tabaci is a complex composed of 28 morphologically indistinguishable species.In this article,we first review the debate and difficulties associated with B.tabaci's taxonomy and systematics,and argue for the need to apply the biological species concept in order to elucidate B.tabaci's systematics.We summarize the accumulated genetic and behavioural data on reproductive incompatibilities evident amongst phylogenetic mtCOI groups of B.tabaci.Crossing studies have been conducted with 14 of the 28 putative species covering 54 reciprocal inter-species pairs,and observations on mating behaviour have been conducted for seven species pairs.Data from both crossing trials and behavioural observations indicate a consistent pattern of reproductive isolation among the putative species.We then discuss the technical and conceptual complexities associated with crossing experiments and behavioural observations designed to reveal reproductive incompatibility.Finally,we elaborate on a strategy for further clarifying the pattern of reproductive isolation between B.tabaci groups and propose future research directions on the systematics of this complex.LIU Shu-sheng John Colvin Paul J De Barro 2012Journal of Integrative Agriculture2012,11,2:76
2Economic Growth and Convergence, Applied to China显示文摘从有条件的集中的观点,自从 1990,瓷器 GDP 生长率令人惊讶地高。然而,中国不能从全球历史的经验永远背离,并且人均的生长率是可能的每年来自整个 8% 很快掉到 3-4% 的一个范围。中国能被看作一个中间收入的集中成功故事,与哥斯达黎加,印度尼西亚,秘鲁,泰国和乌拉圭组织了。高收入的集中成功(向哪个中国多半正在出发) 包括智利,香港,爱尔兰,马来西亚,波兰,新加坡,南朝鲜和台湾。Robert J.

3食道的有鳞的房间癌 - 先锋损害和早诊断显示文摘 Squamous cell carcinoma of the esophagus (SCCE) carries a poor prognosis due to late diagnosis.Early detection is highly desirable,since surgical and endoscopic resection offers the only possible cure for esophageal cancer.Population screening should be undertaken in high risk areas,and in low or moderate risk areas for people with risk factors (alcoholics,smokers,mate drinkers,history of head and neck cancer,achalasia and lye stricture of the esophagus).Esophageal balloon cytology is an easy and inexpensive sampling technique,but the current methods are insufficient for primary screening due to sampling errors.Conventional endoscopy with biopsy remains the standard procedure for the identification of pre-malignant and early malignant changes in esophageal mucosa and endoscopic detection.It may be enhanced by several techniques such as dye and optic chromoendoscopy,magnifying endoscopy,and optical-based spectroscopic and imaging modalities.Since more than 80% of SCCE deaths occur in developing countries,where expensive techniques such as narrow band imaging (NBI) and autofluorescence imaging are unavailable,the most cost-effective tool for targeting biopsies may be Lugol dye chromoendoscopy,since it is easy,accurate,inexpensive and available worldwide.In ideal conditions,or in developed countries,is it reasonable to think that optimal detection will require a combination of techniques,such as the combination of Lugol’s chromoendoscopy and NBI to identify esophageal areas that require further characterization by a high resolution technique.The efficacy and cost-effectiveness will determine whether these modalities will become part of standard endoscopy practice.Antonio Barros Lopes Renato Borges Fagundes 2012World Journal of Gastrointestinal Endoscopy2012,4,1:20
4H 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

6Open abdomen in gastrointestinal surgery:Which technique is the best for temporary closure during damage control?显示文摘AIM To compare the 3 main techniques of temporary closure of the abdominal cavity,vacuum assisted closure(vacuum-assisted closure therapy- VAC),Bogota bag and Barker technique,in damage control surgery.METHODS After systematic review of the literature,33 articles were selected to compare the efficiency of the three procedures.Criteria such as cost,infections,capacity of reconstruction of the abdominal wall,diseases associated with the technique,among others were analyzed.RESULTS The Bogota bag and Barker techniques present as advantage the availability of material and low cost,what is not observed in the VAC procedure.The VAC technique is the most efficient,not only because it reduces the tension on the boarders of the lesion,but also removes stagnant fluids and debris and acts at cellular level increasing cell proliferation and division.Bogota bag presents the higher rates of skin laceration and evisceration,greater need for a stent for draining fluids and wash-ups,higher rates of intestinal adhesion to the abdominal wall.The Barker technique presents lack of efficiency in closing the abdominal wall and difficulty on maintaining pressure on the dressing.The VAC dressing can generate irritation and dermatitis when the drape is applied,in addition to pain,infection and bleeding,as well as toxic shock syndrome,anaerobic sepsis and thrombosis.CONCLUSION The VAC technique,showed to be superior allowing a better control of liquid on the third space,avoiding complications such as fistula with small mortality,low infection rate,and easier capability on primary closure of the abdominal cavity.Marcelo A F Ribeiro Junior Emily Alves Barros Sabrina Marques de Carvalho Vinicius Pereira Nascimento José Cruvinel Neto Alexandre Zanchenko Fonseca 2016World Journal of Gastrointestinal Surgery2016,8,8:9
7Gastrointestinal motility and absorptive disorders in patients with inflammatory bowel diseases: Prevalence, diagnosis and treatment显示文摘Inflammatory bowel diseases(IBD),Crohns disease and ulcerative colitis,are chronic conditions associated with high morbidity and healthcare costs.The natural history of IBD is variable and marked by alternating periods of flare and remission.Even though the use of newer therapeutic targets has been associated with higher rates of mucosal healing,a great proportion of IBD patients remain symptomatic despite effective control of inflammation.These symptoms may include but not limited to abdominal pain,dyspepsia,diarrhea,urgency,fecal incontinence,constipation or bloating.In this setting,commonly there is an overlap with gastrointestinal(GI)motility and absorptive disorders.Early recognition of these conditions greatly improves patient care and may decrease the risk of mistreatment.Therefore,in this review we describe the prevalence,diagnosis and treatment of GI motility and absorptive disorders that commonly affect patients with IBD.Luísa Leite Barros Alberto Queiroz Farias Ali Rezaie 2019World Journal of Gastroenterology2019,25,31:8
8Mechanism of friction reduction of unsaturated fatty acids as additives in diesel fuels显示文摘This paper investigates the effect of unsaturated fatty acid additives on the lubricating properties of a biodiesel,composed of a blend of fatty acid methyl esters(FAMEs)and a conventional diesel fuel.The presence of fatty acids as additives for biodiesel improves their lubricating properties at elevated temperature conditions.The formation of a protective lubricating tribochemical film on the steel contact surfaces has been evidenced.Elevated temperature conditions and possibly oxygen are needed to form this film that reduces friction and limits wear.Several analytical tools have revealed the insulating nature of the formed tribofilm and its chemical properties.Friction-induced reticulation is thought to play a major role in the growth of this insulating film.Jean Michel MARTIN Christine MATTA Maria-Isabel De Barros BOUCHET Cyrielle FOREST Thierry Le MOGNE Thomas DUBOIS Michael MAZARIN 2013Friction2013,1,3:7
9Super-low friction of ta-C coating in presence of oleic acid显示文摘Friction tests have been carried out on bearing steel friction pairs coated with a-C:H and ta-C under lubricated conditions with 1-hexadecene and pure oleic acid,respectively.Main results show that ta-C leads to the super-low regime with oleic acid(friction coefficient below 0.01)and that a-C:H is quite well lubricated by 1-hexadecen.Surface analyses by coupling X-ray photoelectron spectroscopy(XPS)and secondary ion mass spectrometry(SIMS)have been carried out in the case of oleic acid with ta-C and a-C:H coatings.Results show that tribochemical reactions have occurred.OH groups terminate the ta-C surface whereas a-C:H is covered by a thin tribofilm and is terminated by oleic acid monolayers.The superlow regime in the case of ta-C is mainly attributed to the presence of the OH-termination.Makoto KANO Jean Michel MARTIN Kentaro YOSHIDA Maria Isabel DE BARROS BOUCHET 2014Friction2014,2,2:6
10Helicobacter 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
11Bone marrow-derived monocyte infusion improves hepatic fibrosis by decreasing osteopontin,TGF-β1,IL-13 and oxidative stress显示文摘AIM To evaluate the therapeutic effects of bone marrowderived CD11b+CD14+ monocytes in a murine model of chronic liver damage. METHODS Chronic liver damage was induced in C57BL/6 mice by administration of carbon tetrachloride and ethanol for 6 mo. Bone marrow-derived monocytes isolated by immunomagnetic separation were used for therapy. The cell transplantation effects were evaluated by morphometry,biochemical assessment,immunohistochemistry and enzyme-linked immunosorbent assay. RESULTS CD11b+CD14+ monocyte therapy significantly reduced liver fibrosis and increased hepatic glutathione levels. Levels of pro-inflammatory cytokines,including tumor necrosis factor-α,interleukin(IL)-6 and IL-1β,in addition to pro-fibrotic factors,such as IL-13,transforming growth factor-β1 and tissue inhibitor of metalloproteinase-1 also decreased,while IL-10 and matrix metalloproteinase-9 increased in the monocytetreated group. CD11b+CD14+ monocyte transplantation caused significant changes in the hepatic expression of α-smooth muscle actin and osteopontin. CONCLUSION Monocyte therapy is capable of bringing about improvement of liver fibrosis by reducing oxidative stress and inflammation,as well as increasing antifibrogenic factors.Veruska Cintia Alexandrino de Souza Thiago Almeida Pereira Valéria Wanderley Teixeira Helotonio Carvalho Maria Carolina Accioly Brelaz de Castro Carolline Guimaraes D’assuncao Andreia Ferreira de Barros Camila Lima Carvalho Virgínia Maria Barros de Lorena Vláudia Maria Assis Costa Alvaro Aguiar Coelho Teixeira Regina Celia Bressan Queiroz Figueiredo Sheilla Andrade de Oliveira 2017World Journal of Gastroenterology2017,23,28:6

14The Bemisia tabaci Species Complex:Questions to Guide Future Research显示文摘Since 2007 we have began to consider the relationships between the different members of the Bemisia tabaci species complex in a more structured and systematic way.Much of these relationships has been infered from considerations of a portion of the mitochondrial cytochrome oxidase one(mtCOI)gene.While this is a quite limited approach which would benefit from the consideration of a much greater diversity of genetic material,it is the only publically available data that spans the diversity of the species complex.Despite the limitations,the phylogenetic reconstruction that can be derived from this data is useful and can be used as a basis to frame questions and construct testable hypotheses that will form the basis for future research.This study uses the largest available mtCOI dataset,consisting of 383 unique mtCOI haplotypes that spans the full diversity of the B.tabaci species complex as we currently know it,to make a range of observations which are then used to develop questions as guide for future research.Paul J De Barro 2012Journal of Integrative Agriculture2012,11,2:5

16No evidence of HPV DNA in esophageal squamous cell carcinoma in a population of Southern Brazil显示文摘AIM:To investigate the association between human papillomavirus(HPV)and esophageal squamous cell carcinoma(ESCC)in southern Brazil.METHODS:We studied 189 esophageal samples from125 patients from three different groups:(1)102 biopsies from 51 patients with ESCC,with one sample from the tumor and another from normal esophageal mucosa distant from the tumor;(2)50 esophageal biopsies from 37 patients with a previous diagnosis of head and neck squamous cell carcinoma(HNSCC);and(3)37 biopsies from esophageal mucosa with normal appearance from 37 dyspeptic patients,not exposed to smoking or alcohol consumption.Nested-polymerase chain reaction(PCR)with the MY09/11 and GP5/6 L1primers was used to detect HPV L1 in samples fixed in formalin and stored in paraffin blocks.All PCR reactions were performed with a positive control(cervicovaginal samples),with a negative control(Human Genomic DNA)and with a blank reaction containing all reagents except DNA.We took extreme care to prevent DNA contamination in sample collection,processing,and testing.RESULTS:The histological biopsies confirmed the diagnosis of ESCC in 52 samples(51 from ESCC group and 1 from the HNSCC group)and classified as well differentiated(12/52,23.1%),moderately differentiated(27/52,51.9%)or poorly differentiated(7/52,13.5%).One hundred twenty-eight esophageal biopsies were considered normal(51 from the ESCC group,42 from the HNSCC group and 35 from dyspeptic patients).Nine had esophagitis(7 from the HNSCC and 2 from dyspeptic patients).Of a total of 189 samples,only 6 samples had insufficient material for PCR analysis:1 from mucosa distant from the tumor in a patient with ESCC,3from patients with HNSCC and 2 from patients without cancer.In 183 samples(96.8%)GAPDH,G3PDH and/orβ-globin were amplified,thus indicating the adequacy of the DNA in those samples.HPV DNA was negative in all the 183 samples tested:52 with ESCC,9 with esophagitis and 122 with normal esophageal mucosa.CONCLUSION:There was no evidence of HPV infection in different ESCC from southern Brazil.Luís Carlos Moreira Antunes Joo Carlos Prolla Antonio de Barros Lopes Marta Pires da Rocha Renato Borges Fagundes 2013World Journal of Gastroenterology2013,19,39:4
17Perspectives on new biomarkers in gastric cancer: Diagnostic and prognostic applications显示文摘Gastric cancer is considered one of the most deadly tumors worldwide. Even with the decline in its incidence, the mortality rate of this disease has remained high, mainly due to its late diagnosis and to the lack of precise prognostic markers. The main purpose of this review is to present genetic, epigenetic and proteomic molecular markers that may be used in a diagnostic and prognostic manner and to discuss the pros and cons of each type of marker for improving clinical practice. In this sense, we observed that the use of genetic markers, especially mutations and polymorphisms, should be carefully considered, as they are strongly affected by ethnicity. Proteomic-based markers show promise, but the higher costs of the associated techniques con-tinue to make this approach expensive for routine use. Alternatively, epigenetic markers appear to be very promising, as they can be detected in bodily fluids as well as tissues. However, such markers must be used carefully because epigenetic changes may occur due to environmental factors and aging. Despite the advances in technology and its access, to date, there are few defined biomarkers of prognostic and diagnostic use for gastric tumors. Therefore, the use of a panel of several approaches(genetic, epigenetic and proteomic) should be considered the best alternative for clinical practice.Danilo do Rosário Pinheiro Wallax Augusto Silva Ferreira Mariceli Baia Leo Barros Mariana Diniz Araújo Symara Rodrigues-Antunes Bárbara do Nascimento Borges 2014World Journal of Gastroenterology2014,20,33:4
18Plasma phospholipid transfer protein (PLTP) modulates adaptive immune functions through alternation of T helper cell polarization显示文摘客观:血浆 phospholipid 转移蛋白质(PLTP ) 是脂蛋白新陈代谢的一个关键决定因素,并且动物和人的研究收敛显示 PLTP 支持 atherogenesis 和它的 thromboembolic 复杂并发症。而且, PLTP 调制发炎和有免疫力的回答,这最近被报导了。尽管从我们的组的更早的研究证明 PLTP 能修改巨噬细胞激活,在 T-cell-mediated 有免疫力的回答的调整的 PLTP 的含意从来没被调查过并且因此在现在的学习被探讨。途径和结果:在现在的学习,我们证明在老鼠的那 PLTP 缺乏在 CD4 + Th0 房间极化上有深刻效果,与向在正常、病理学的条件下面的反煽动性的 Th2 显型的移动。在接触超敏性的一个模型,对有 hapten-2,4-dinitrofluorobenzene (DNFB ) 的皮肤促进感受性的显著地损害的回答在 PLTP 缺乏的老鼠被观察与相比野类型(WT ) 老鼠。有趣地,在老鼠的 PLTP 缺乏没在外部血在全部的白血房间,淋巴细胞, granulocytes,或单核白血球的计数上施加效果。而且, PLTP 缺乏没修改 CD4 + 和 CD8 + T 淋巴细胞子集的数量。然而, PLTP 缺乏,与 Th2 显型的 upregulation 联系了,被重要减少在 pro-Th1 cytokine interleukin 的生产伴随 18 由附件房间。结论:第一次,这个工作向支持 inflammatory Th1 显型在 CD4 + T 房间的极化为 PLTP 报导一个生理的角色。Catherine Desrumau Stephanie Lemaire-Ewing Nicolas Ogier Akadiri Yessoufou Arlette Hammann Anabelle Sequeira-Le Grand Valerie Deckert Jean-Paul Pais de Barros Naig Le Guern Julien Guy Naim A Khan Laurent Lagrost 2016Cellular & Molecular Immunology2016,13,6:3
