| 1 | Species 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 | 2012 | Journal of Integrative Agriculture2012,11,2: | 76 |
| 2 | H 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 | 2008 | World Journal of Gastroenterology2008,14,6: | 17 |
| 3 | Open 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 | 2016 | World Journal of Gastrointestinal Surgery2016,8,8: | 9 |
| 4 | Mechanism 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 | 2013 | Friction2013,1,3: | 7 |
| 5 | Super-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 | 2014 | Friction2014,2,2: | 6 |
| 6 | Helicobacter 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 | 2010 | World Journal of Gastroenterology2010,16,3: | 6 |
| 7 | Bone 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 | 2017 | World Journal of Gastroenterology2017,23,28: | 6 |

| 9 | The 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 | 2012 | Journal of Integrative Agriculture2012,11,2: | 5 |
| 10 | No 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 Joo Carlos Prolla Antonio de Barros Lopes Marta Pires da Rocha Renato Borges Fagundes | 2013 | World Journal of Gastroenterology2013,19,39: | 4 |

| 12 | Proton nuclear magnetic resonance-based metabonomic models for non-invasive diagnosis of liver fibrosis in chronic hepatitis C:Optimizing the classification of intermediate fibrosis显示文摘AIM To develop metabonomic models(MMs), using 1 H nuclear magnetic resonance(NMR) spectra of serum, to predict significant liver fibrosis(SF: Metavir ≥ F2), advanced liver fibrosis(AF: METAVIR ≥ F3) and cirrhosis(C: METAVIR = F4 or clinical cirrhosis) in chronic hepatitis C(CHC) patients. Additionally, to compare the accuracy of the MMs with the aspartate aminotransferase to platelet ratio index(APRI) and fibrosis index based on four factors(FIB-4). METHODS Sixty-nine patients who had undergone biopsy in the previous 12 mo or had clinical cirrhosis were included. The presence of any other liver disease was a criterion for exclusion. The MMs, constructed using partial least squares discriminant analysis and linear discriminant analysis formalisms, were tested by cross-validation, considering SF, AF and C. RESULTS Results showed that forty-two patients(61%) presented SF, 28(40%) AF and 18(26%) C. The MMs showed sensitivity and specificity of 97.6% and 92.6% to predict SF; 96.4% and 95.1% to predict AF; and 100% and 98.0% to predict C. Besides that, the MMs correctly classified all 27(39.7%) and 25(38.8%) patients with intermediate values of APRI and FIB-4, respectively. CONCLUSION The metabonomic strategy performed excellently in predicting significant and advanced liver fibrosis in CHC patients, including those in the gray zone of APRI and FIB-4, which may contribute to reducing the need for these patients to undergo liver biopsy. | Andrea Dória Batista Carlos Jonnatan Pimentel Barros Tássia Brena Barroso Carneiro Costa Michele Maria Goncalves de Godoy Ronaldo Dionísio Silva Joelma Carvalho Santos Mariana Montenegro de Melo Lira Norma ThoméJucá Edmundo Pessoa de Almeida Lopes Ricardo Oliveira Silva | 2018 | World Journal of Hepatology2018,10,1: | 2 |
| 13 | Gut-microbiome-brain axis:the crosstalk between the vagus nerve,alpha-synuclein and the brain in Parkinson's disease显示文摘This critical review of the literature shows that there is a close link between the microbiome,the gut,and the brain in Parkinson's disease.The vagus nerve,the main component of the parasympathetic nervous system,is involved in the regulation of immune response,digestion,heart rate,and control of mood.It can detect microbiota metabolites through its afferents,transferring this gut information to the central nervous system.Preclinical and clinical studies have shown the important role played by the gut microbiome and gut-related factors in disease development and progression,as well as treatment responses.These findings suggest that the gut microbiome may be a valuable target for new therapeutic strategies for Parkinson's disease.More studies are needed to better understand the underlying biology and how this axis can be modulated for the patient's benefit. | Júlio César Claudino dos Santos Leandro Freitas Oliveira Felipe Micelli Noleto Camilla Teixeira Pinheiro Gusmão Gerly Anne de Castro Brito Glauce Socorro de Barros Viana | 2023 | Neural Regeneration Research2023,18,12: | 2 |
