Uji Aktivitas Antidiabetes Ekstrak Etanol Daun Sawo Kecik (Manilkara kauki (L) Dubard) pada Tikus Jantan Galur Wistar
Get PDFDiabetes mellitus is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action or both. HbA1c examination is also the best examination to assess the risk of tissue damage caused by high blood glucose levels. This study aims to determine the antidiabetic effect of EEDSK on decreasing blood glucose (KGD), HbA1c levels, and repair of pancreatic β cells in STZ-NA-induced rats. This study used 24 rats which were divided into 6 groups. EEDSK doses used in this study were 125, 250, and 500 mg/kg BW, Glibenclamide 0.45 mg/kg BW was used as a positive control and Na-CMC as a negative control, the normal group was used in this study. Diabetic rats were given sapodilla leaf extract every day. Blood glucose levels were measured on days 4, 8, 12, 16, 20, 24, and 28, while HbA1c and Histopathology levels were measured on day 28.
The results of the phytochemical screening contained in sapodilla leaf extract were flavonoids, tannins, glycosides, saponins, and steroids/terpenoids. The results of statistical analysis showed that giving EEDSK doses of 500, 250, and 125 mg/kg BW could significantly reduce KGD compared to the negative control group. Giving EEDSK doses of 500, 250, and 125 mg/kg BW was able to reduce HbA1c levels in nicotinamide and streptozotocin-induced rats. The results of staining with the hematoxylin-eosin method showed a significant change in that EEDSK was able to improve the histopathological picture of the pancreas and increase the surface area of the islets of Langerhans in STZ-NA-induced diabetic rats. Based on the description it can be concluded that EEDSK can reduce blood glucose levels (KGD), and HbA1c levels and improve the histopathological picture of damaged pancreas.166 HalamanTesis Magiste
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
TEST OF ANTIBACTERIAL ACTIVITY FROM THE COMBINATION OF ETHANOL EXTRACT OF WARU (HIBUSCUSTILIACEUS L.) LEAVES AND LEAF RED PUCUK (SYZYGIUM OLEANA) AGAINST SALMONELLA THYPI ON 2021
Get PDFThe research in this paper aims to determine the effectiveness of immunostimulants from ethanol extract of coffee parasite leaves (Loranthus ferrugineus Roxb) with four variants of doses of 50mg / kgBB, 100mg / kgBB, 200mg / kgBB, 400mg / kgBB. This study used 18 male white rats with 200 gram BB which were divided into 6 treatment groups. Rats were injected with 0.1ml SDMS 1% for 7 consecutive days intraperitoneal, then on the 7th day each blood sample was taken through veins in the tail, CMC Na 0.5% suspension, and Levamisole suspension 50mg / kgBB as a positive control was administered orally on the 8th day. Then blood samples were collected in a micro tube and then 1900rpm was centrifuged at a temperature of 4oC for 10 minutes. The results of the study of ethanol extract of coffee parasite leaves proved effective as immunostimulants because they have a value close to positive control, starting from a dose of 200mg / kgBB to 400mg / kgBB
Variations on the Author
Get PDF“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
Get PDFWe 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
WORKSHOP OF TESTING THE EFFECTIVENESS OF ANTIBACTERIAL EXTRACT OF SURUHAN (peperomia pellucida l. Kunth) LEAVES AGAINST staphylococcus epidermidis BACTERIA
Get PDFSkin infections or dermatitis are included in the ten most common diseases in Indonesia, so the use of antibiotics is very high. The increasing use of antibiotics will cause an increase in the use of inappropriate antibiotics. The purpose of this research and community service was to find out the leaf extract of suruhan (Peperomia pellucida L. Kunth) with a variety of solvents providing anti-microbial activity against Staphylococcus epidermidis bacteria and conveying information to the public about the leaf extract that can be used as an acne medication. The results showed that the inhibition of ethanol extract and aquadest leaves of suruhan against the growth of Staphylococcus epidermidis bacteria at a concentration of 25 mg/mL clear zone 6.0 mm ethanol extract and 5.4 mm aquadest extract (Potentially Weak), concentration 50 mg/mL diameter of the extract inhibition zone ethanol 8.46 mm and aquadest extract 6.53 mm (medium potential), concentration 75 mg/mL diameter of inhibition zone 12.96 mm ethanol extract and 8.53 mm aquadest extract (strong potential). From the research data obtained, it is socialized to the public regarding the antibacterial activity of the leaves of suruhan against Staphylococcus epidermidis bacteria. The purpose of Community Service (PKM) is to provide information to the public that suruhan leaves can be used as an antibacterial to inhibit bacterial growth even with various types of solvent concentrations used. The conclusion in this study is that there are many plants that can be used to inhibit the growth and development of acne-causing bacteria, one of which is the leaf plant among young people
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
