| 1 | Promoter hypermethylation of CDH1, FHIT, MTAP and PLAGL1 in gastric adenocarcinoma in individuals from Northern Brazil显示文摘AIM: To evaluate the methylation status of CDH1, FHIT, MTAP and PLAGL1 promoters and the association of these findings with clinico-pathological characteristics. METHODS: Methylation-specific PCR (MSP) assay was performed in 13 nonneoplastic gastric adenocarcinoma, 30 intestinal-type gastric adenocarcinoma and 35 diffuse- type gastric adenocarcinoma samples from individuals in Northern Brazil. Statistical analyses were performed using the chi-square or Fisher’s exact test to assess associations between methylation status and clinico- pathological characteristics. RESULTS: Hypermethylation frequencies of CDH1, FHIT, MTAP and PLAGL1 promoter were 98.7%, 53.9%, 23.1% and 29.5%, respectively. Hypermethylation of three or four genes revealed a significant association with diffuse-type gastric cancer compared with nonneoplastic cancer. A higher hypermethylation frequency wassignificantly associated with H pylori infection in gastric cancers, especially with diffuse-type. Cancer samples without lymph node metastasis showed a higher FHIT hypermethylation frequency. MTAP hypermethylation was associated with H pylori in gastric cancer samples, as well as with diffuse-type compared with intestinal-type. In diffuse-type, MTAP hypermethylation was associated with female gender. CONCLUSION: Our findings show differential gene methylation in tumoral tissue, which allows us to conclude that hypermethylation is associated with gastric carcinogenesis. MTAP promoter hypermethylation can be characterized as a marker of diffuse-type gastric cancer, especially in women and may help in diagnosis, prognosis and therapies. The H pylori infectious agent was present in 44.9% of the samples. This infection may be correlated with the carcinogenic process through the gene promoter hypermethylation, especially the MTAP promoter in diffuse-type. A higher H pylori infection in diffuse-type may be due to greater genetic predisposition. | Mariana Ferreira Leal Eleonidas Moura Lima Patrícia Natália Oliveira Silva Paulo Pimentel Assumpo Danielle Queiroz Calcagno Spencer Luiz Marques Payo Rommel Rodríguez Burbano Marília de Arruda Cardoso Smith | 2007 | World Journal of Gastroenterology2007，13，18： | 24 |
| 2 | Playing Well on the Data FAIRground:Initiatives and Infrastructure in Research Data Management显示文摘Over the past five years,Elsevier has focused on implementing FAIR and best practices in data management,from data preservation through reuse.In this paper we describe a series of efforts undertaken in this time to support proper data management practices.In particular,we discuss our journal data policies and their implementation,the current status and future goals for the research data management platform Mendeley Data,and clear and persistent linkages to individual data sets stored on external data repositories from corresponding published papers through partnership with Scholix.Early analysis of our data policies implementation confirms significant disparities at the subject level regarding data sharing practices,with most uptake within disciplines of Physical Sciences.Future directions at Elsevier include implementing better discoverability of linked data within an article and incorporating research data usage metrics. | Danielle Descoteaux Chiara Farinelli Marina Soares e Silva Anita de Waard | 2019 | Data Intelligence2019，1，4： | 3 |
| 3 | Structural phase relations in perovskite-structured BiFeO_(3)-based multiferroic compounds显示文摘In this review,the state of the art in understanding the structural phase relations in perovskite-structured BiFeO_(3)-based polycrystalline solid solutions is presented and discussed.Issues about the close relation between the structural phase and overall physical properties of the reviewed systems are pointed out and discussed.It is shown that,by adjusting the structural symmetric arrangement,the ferroelectric and magnetic properties of BiFeO_(3)-based polycrystalline solid solutions can be tuned to find specific multifunctional applications.However,an intrinsic mechanism linking structural arrangement and physical properties cannot be identified,revealing that this subject still deserves further discussion and investigation. | Valdirlei Fernandes FREITAS Gustavo Sanguino DIAS Otávio Algusto PROTZEK Diogo Zampieri MONTANHER Igor Barbosa CATELLANI Daniel Matos SILVA Luiz Fernando CÓTICA Ivair Aparecido dos SANTOS | 2013 | Journal of Advanced Ceramics2013，2，2： | 2 |
| 4 | Emergency medical services use and its association with acute ischaemic stroke evaluation and treatment in Singapore显示文摘Background Emergency medical services(EMS)is a critical link in the chain of stroke survival.We aimed to assess EMS use for stroke in Singapore,identify characteristics associated with EMS use and the association of EMS use with stroke evaluation and treatment.Methods The Singapore Stroke Registry combines nationwide EMS and public hospital data for stroke cases in Singapore.Multivariate regressions with the generalised estimating equations were performed to examine the association between EMS use and timely stroke evaluation and treatment.results Of 3555 acute ischaemic patients with symptom onset within 24 hours admitted to all five public hospitals between 2015 and 2016,68%arrived via EMS.Patients who used EMS were older,were less likely to be female,had higher stroke severity by National Institute of Health Stroke Scale and had a higher prevalence of atrial fibrillation or peripheral arterial disease.Patients transported by EMS were more likely to receive rapid evaluation(door-to imaging time≤25 min 34.3%vs 11.1%,OR=2.74(95%CI 1.40 to 5.38))and were more likely to receive intravenous tissue plasminogen activator(tPA,22.8%vs 4.6%,OR=4.61(95%CI 3.52 to 6.03)).Among patients treated with tPA,patients who arrived via EMS were more likely to receive timely treatment than self-transported patients(door-to needle time≤60 min 52.6%vs 29.4%,OR=2.58(95%CI 1.35 to 4.92)).Conclusions EMS use is associated with timely stroke evaluation and treatment in Singapore.Seamless EMS-Hospital stroke pathways and targeted public campaigns to advocate for appropriate EMS use have the potential to improve acute stroke care. | Hanzhang Xu Ying Xian Fung Peng Woon Janet Prvu Bettger Daniel T Laskowitz Yih Yng Ng Marcus Eng Hock Ong David Bruce Matchar Deidre Anne De Silva | 2020 | Stroke & Vascular Neurology2020，5，2： | 2 |
