Status Resistensi Nyamuk Aedes aegypti terhadap Malation dan Mutasi Gen Ace-1 di Kota Ambon
Full text linkAbstract
Aedes aegypti is the main vector of Dengue Hemorrhagic Fever (DHF). The continuous use of insecticides can cause resistant Ae. aegypti. One indicator of mosquito resistance to organophosphate is acetylcholinesterase insensitivity, which is encoded by the ace-1 gene. This study aims to analyze the status of resistance and detect ace-1 gene mutations in Ae. aegypti in Ambon city. This research is a descriptive and analytic study with a cross-sectional research design. Resistance status was tested by the CDC bottle bioassay and the detection of ace-1 gene mutations was established using PCR and sequencing. The nucleotide sequence was edited with Mega 7 software. The results of resistance tests using the CDC bottle bioassay method showed Ae. aegypti from the Waihaong and Rijali Community Health Centers had a mortality of 92% and 95.83% (tolerant), while the Latuhalat, Amahusu, Air Salobar, Benteng, Urimessing, Christina Martha Thiahahu, Karpan, Belso, Air Besar, Kilang, Halong, Lateri, Passo, and Nania had mortality between 98-100% (vulnerable). Sequencing and alignment results showed that there were no ace-1 gene mutations in Ae. aegypti originating from Waihaong and Rijali Community Health Centers. Ae. aegypti resistance status in 2 Community Health Centers is tolerant and 14 other Community Health Centers are vulnerable. There are no ace-1 gene mutations in Ae. aegypti at the Waihaong and Rijali Community Health Centers in Ambon City.
Abstrak
Nyamuk Aedes aegypti adalah vektor utama penyakit demam berdarah dengue (DBD). Penggunaan insektisida terus menerus dapat menyebabkan nyamuk Ae. aegypti resisten. Salah satu indikator resistensi nyamuk terhadap insektisida organofosfat adalah insensitivitas acetylcholinesterase, yang dikode oleh gen ace-1. Penelitian ini bertujuan menganalisis status resistensi dan mendeteksi mutasi gen ace-1 pada nyamuk Ae. aegypti di kota Ambon. Penelitian ini merupakan penelitian deskriptif dan analitik dengan rancangan penelitian cross sectional. Status resistensi diuji dengan metode CDC bottle bioassay dan deteksi mutasi gen ace-1 ditegakkan menggunakan PCR dan sekuensing. Urutan nukleotida diedit dengan software Mega 7. Hasil uji resistensi dengan metode CDC bottle bioassay menunjukan nyamuk Ae. aegypti dari Puskesmas Waihaong dan Rijali memiliki mortalitas 92% dan 95,83% (toleran), sedangkan Puskesmas Latuhalat, Amahusu, Air Salobar, Benteng, Urimessing, Chrsitina Martha Thiahahu, Karpan, Belso, Air Besar, Kilang, Halong, Lateri, Passo, dan Nania memiliki mortalitas antara 98-100% (rentan). Hasil sekuensing dan alignment menunjukan tidak terdapat mutasi gen ace-1 pada nyamuk Ae. aegypti yang berasal dari Puskesmas Waihaong dan Rijali. Status resistensi nyamuk Ae. aegypti di 2 Puskesmas Kota Ambon tergolong toleran dan 14 Puskesmas lainnuya tergolong rentan. Tidak terdapat mutasi gen ace-1 pada nyamuk Ae. aegypti di Puskesmas Waihaong dan Rijali Kota Ambon
FAKTOR-FAKTOR YANG BERHUBUNGAN DENGAN LOW BACK PAIN DI WILAYAH KERJA PUSKESMAS WAMLANA KABUPATEN BURU
Full text linkLow back pain merupakan gejala yang di tandai dengan nyeri di daerah punggung bagian bawah dan bisa menyebar sampai ke daerah sekitar. Faktor penyebabnya antara lain usia, masa kerja, posisi duduk, lama kerja, Semakin bertambahnya usia, fungsi tubuh akan mengalami penurunan. Waktu berkerja yang lama, dengan posisi duduk yang salah dapat menimbulkan nyeri pada dearah punggung bawah. Tujuan: Untuk mengetahui faktor-faktor yang berhubungan dengan low back pain di wilayah kerja Puskesmas Wamlana kabupaten buru. Deskriptif analitik dengan rancangan cross sectional. Sampel berjumlah 34 responden yang diambil menggunakan Teknik total sampling. Berdasarkan uji Fisher exact terdapat hubungan antara low back pain dengan usia (p=0,048), masa kerja (p=0,029), posisi duduk (p=0,015) dan lama kerja (pe=0,006).Anjuran untuk penderita ialah periksakan kesehatan secara berkala sedangkan untuk lembaga kesehatan agar terus melaksanakan aksi pengobatan melalui asuhan keperawatan serta promosi kesehatan secara komperhensif.Penderita low back pain di sarankan untuk lebih banyak membuat jadwal kerja agar tidak terlalu lama karena sangat memperburuk kondisi
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
