Analgesic Activity of Bitter Melon Leaves Ethanol Extract in Mice (Mus musculus)
No full textPain is an unpleasant sensation and can be felt as sore sensation. This can be caused by mechanical, chemical or physical stimulation that could cause damage to the tissueand trigger the release of certain substances called pain mediators, such as histamine, bradykinin, leukotrienes and prostaglandins. Pain overcome by giving analgesic drugs. This study aims to determine the effectivity and effective duration of bitter melon (Momordica charantia L.) leaf extract as analgesic in mice (Mus musculus). The test method used in this study is the Hot plate method. This study was divided into 5 treatment groups animals with 5 experimental animals in each group. Animal treatment of this study consist of a negative control group using CMC-Na (0.5%), a positive control group using Paracetamol, a suspension group of pare leaf ethanol extract with a dose of 0.212mg / 20gBW. , the ethanol extract suspension group of bitter melon leaves with a dose of 0.423mg / 20gBW, the suspension group of ethanol extract of pare leaves with a dose of 0.635mg / 20gBW. The results of this study indicate that the ethanol extract of 96% bitter melon leaves has activity as an analgesic in mice with the best dose of 0.635mg / 20gBW and the highest duration of analgesic activity was in 40 minutes, these activity was the closest result to positive control of paracetamol in mice
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
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
Effectiveness Of Tajin Water (Rice-Water) As A Coupling Food To Improve Weight Board (Mus Musculus)
Get PDFMalnutrition can occur on children of aged 6 to 24 months. During this period, there is generally a change in needs from exclusive breastfeeding to complementary foods and additional food can also be added. Starch water which is a springy white liquid obtained from rice that is cooked with the nutritional content of energy, protein, fat, carbohydrates, calcium, iron, vitamin B1. This study aims to test the effectiveness, determine the best concentration and determine the influence of the length time from using of starch water as an additional complementary food to increase body weight of male mice (Mus musculus) for 21 days by oral treatment. The experiment and method that used in this experiment is was pretest-posttest control group design. Starch water is obtained by means of rice being heated with 1200 mL of water for ± 30 minutes, filtering and extracting is obtained. Starch water concentrations commonly used empirically tested in this study are concentrations of 12.5%; 18.7%; 25%. The 25% concentration is the concentration that has an effective effect on body weight of mice with the results (21.87 ± 4.29) which differ 2.38% from the positive control results (24.25 ± 8.93)
Pengaruh Habitat Sekitar Lahan Persawahan dan Umur Tanaman Padi terhadap Keanekaragaman Hymenoptera Parasitika
No full textHymenoptera Parasitika merupakan kelompok agen pengendali hayati terbesar dan memiliki peranan penting dalam mengendalikan hama di habitat pertanian. Walaupun demikian, informasi mengenai bagaimana parasitoid ini terdapat di habitat pertanian masih sangat sedikit khususnya yang berhubungan dengan kondisi habitat sekitar lahan pertanian dan fenologi dari tanaman pertanian. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh habitat sekitar lahan persawahan dan umur tanaman padi terhadap keanekaragaman Hymenoptera Parasitika. Lokasi penelitian merupakan lahan persawahan yang terletak di Desa Carang Pulang, Dramaga, Bogor. Lahan persawahan dibedakan menjadi empat blok yang merepresentasikan berbagai kondisi habitat dan umur tanaman padi yang berbeda. Di setiap blok dipasang enam perangkap kuning (dengan jarak minimal 20 meter) dan satu perangkap malaise. Pengambilan contoh serangga dilakukan setiap minggu dari umur 6 hingga 12 minggu setelah tanam. Melalui penelitian ini, berhasil dikoleksi 1.833 individu Ordo Hymenoptera (tanpa semut) yang terdiri dari 9 superfamili, 23 famili, dan 216 spesies. Hymenoptera Parasitika ditemukan lebih melimpah (96%) dan lebih beranekaragam (84%) dibandingkan kelompok Aculeata. Kondisi habitat sekitar lahan persawahan (blok) dan umur tanaman padi berpengaruh terhadap keane-karagaman Hymenoptera Parasitika. Terdapat hubungan positif antara umur tanaman padi dengan kekayaan spesies Hymenoptera Parasitika.</jats:p
Pengaruh Habitat Sekitar Lahan Persawahan dan Umur Tanaman Padi terhadap Keanekaragaman Hymenoptera Parasitika
Get PDFAs the largest group of biological control agents, Parasitic Hymenoptera play important role in controlling pest outbreak in agricultural habitat. Unfortunately, there is lack of information about how these parasitoids occur in agricultural habitat related to condition of surrounding habitat and phenology of crop plant. The objective of this research was to study the effect of rice field surrounding habitat and age of rice plant on the diversity of Parasitic Hymenoptera. Research area was located in Carang Pulang Village, Dramaga, Bogor. We selected four blocks which represented different of habitat condition and age of rice plant. Each block was set six yellow pan traps (with minimum distance 20 meter) and one malaise trap. Sampling of insects were conducted weekly from 6 to 12 week after planting. From this research, we collected 1,833 individual of Hymenoptera (without ants) belong to 9 superfamilies, 23 families, and 216 species. Parasitic Hymenoptera was more abundant (96%) and species rich (84%) than Aculeata. Rice field surrounding habitat (block) and age of rice field significantly affect the diversity of Parasitic Hymenoptera. We found positively correlation between age of rice plant and species richness of Parasitic Hymenoptera
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
