First Report of Tomato leaf curl New Delhi virus Infecting Cucumber in Central Java, Indonesia

Abstract: Cucumber (Cucumis sativus L.) is an important vegetable in Indonesia. Cucumber plants showing yellowy green mosaic symptoms on leaves were observed in Klaten, Central Java, Indonesia in August 2008. Total DNAs were extracted from symptomatic leaves, and the putative viral genomes were amplified by PCR with the Deng A and B primers (2). The PCR-amplified viral genomic DNA was sequenced. The remaining part of DNA-A was amplified with two primers sets (ToLCNDV-A1F 5'-ACCAACAGGCCGATGAACA-3' and ToLCNDV-A1R 5'-TTCCCACTATCTTCCTGTGCA-3'; ToLCNDV-A2F 5'-TCGAGTGTGATRAAGAYTGCA-3' and ToLCNDV-A2R 5'-ACTAACTAAGCATTGCAGCGTC-3' [R = A and G, Y = C and T]) and sequenced. The remaining part of DNA-B was amplified with two primers sets (ToLCNDV-B1F 5'-ARGAGTTYMCRYYTGTGGA-3' and ToLCNDV-B1R 5'-TKCWGTYGGTCATGTCGT-3'; ToLCNDV-B2F 5'-TCYGTCAATCKCATGTCGYGT-3' and ToLCNDV-B2R 5'-CCTTACGCGTATAYTGTYTRGA-3' [K = G and T, M = A and C, W = A and T]) and sequenced. Full-length DNA-A (2,739 nt; GenBank Accession No. AB613825) and DNA-B (2,690 nt; GenBank Accession No. AB613826) sequences of a bipartite Tomato leaf curl New Delhi virus (ToLCNDV) from Central Java were obtained and they were most similar to the corresponding sequences of both DNA-A and DNA-B of ToLCNDV-[cucumber:Thailand] (DNA-A, GenBank Accession No. AB330079; DNA-B, GenBank Accession No. AB330080) at 95.5 and 91.0% nucleotide identities, respectively. On the basis of high nucleotide sequence identity with ToLCNDV-[cucumber:Thailand] and the demarcation criteria in species identification (3), the virus isolate from the diseased cucumber in Central Java is considered as a variant of ToLCNDV and was accordingly named ToLCNDV-Indonesia[Indonesia:Java:Cucumber:2008] (ToLCNDV-ID[ID:Jav:Cuc:08]). Although the importance of begomovirus diseases on chili pepper (Solanaceae) is currently highly noticed in Indonesia (1), ToLCNDV was newly isolated from cucumber (Cucurbitaceae) in this study. Therefore, farmers in Indonesia should pay more attention to controlling begomovirus vectors, white flies, on Cucurbitaceae. To our knowledge, this is the first report of the natural occurrence of ToLCNDV in Indonesia. References: (1) P. J. D. Barro et al. Biol. Invas.10:411, 2008. (2) D. Deng et al. Ann. Appl.

Topic or Style? Exploring the Most Useful Features for Authorship Attribution

Abstract: Approaches to authorship attribution, the task of identifying the author of a document, are based on analysis of individuals’ writing style and/or preferred topics. Although the problem has been widely explored, no previous studies have analysed the relationship between dataset characteristics and effectiveness of different types of features. This study carries out an analysis of four widely used datasets to explore how different types of features affect authorship attribution accuracy under varying conditions. The results of the analysis are applied to authorship attribution models based on both discrete and continuous representations. We apply the conclusions from our analysis to an extension of an existing approach to authorship attribution and outperform the prior state-of-the-art on two out of the four datasets used.

Diabetes management and specific considerations for patients with diabetes during coronavirus diseases pandemic: A scoping review.

Abstract: Background and aims The global pandemic of coronavirus (COVID-19) affects almost all countries in the world, which potentially alter diabetes management. Many diabetes patients are experiencing barrier of care due to the policy related to COVID-19. This article aims to review the current evidence on diabetes management and specific considerations during the COVID-19 pandemic for people living with diabetes. Methods We conducted a scoping review in PubMed, Science Direct, DOAJ and Microsoft Academics databases from January 1 to April 17, 2020. Searching terms included “COVID-19”, “severe acute respiratory syndrome coronavirus 2”, and “Diabetes Mellitus” were used. Only scientific articles discussing diabetes management and specific considerations were selected and extracted. Results A total of 7 articles was selected in the analysis. Most were published in diabetes journals (85.71%). All articles (100%) discussed diabetes management and 71.43% of them provided diabetes care in specific considerations. We discussed issue of diabetes management in glycemic control and monitoring, dietary intake, physical activity, medication, education and prevention of COVID-19 infection that applicable for diabetes patients. In addition, specific considerations explored caring for diabetes in children and adolescents, pregnancy, elderly, emergency or critical care, to offer certain concern for raising the awareness. Conclusions This review specifies a summary of diabetes management as well as the particular considerations to care people living with diabetes during COVID-19 pandemic. Patients, health care providers, and policy makers could take advantage of the review to assist diabetic people passing through COVID-19 pandemic session with optimum glycemic outcome.
