Sub acute oral toxicity screening on jellyfish Lobonema smithi consumption in Sprague Dawley rats
No full textConsumption of jellyfish has been reported to be effective in treating several illnesses and has been a unique delicacy in most
of East Asia countries. However, toxicity effect of the jellyfish consumption has not been reported although it has been eaten
for generations. The aim of this study is to evaluate the toxicity effects on the consumption of white jellyfish Lobonema
smithi in rat model. Toxicity effects were evaluated according to Fixed Dose Procedure OECD guidelines 420 which include
determination of 50% of lethal dose (LD50), changes in body and relative organs weight, differential leucocytes count and
histopathological analysis of the liver and kidney. Twenty-four female Sprague Dawley rats (180-220 g) were used in the
study and were orally treated with different dosage of freeze dried L. smithi powder (100, 500, 2000 mg/kg of body weight
respectively) for 14 days. Half of the rats from each group (n=3) were euthanized on day 14 for sub-acute study to obtain
relative organs weight, haematology and histopathological analysis. Another half of the animals from each groups (n=3)
were kept for another 14 days without any treatment for delayed toxicity studies. There were, no lethality observed at all
dosage given and the LD50 value was evaluated to be more than 2000 mg/kg of body weight. Furthermore, no significant
(p>0.05) changes were observed in animal body and relative organs weight, differential leucocytes counts, food consumption
and water intake in all treatment groups compared to untreated animal for both sub-acute and delayed toxicity study. Moreover,
histology analysis on liver and kidney from sub-acute and delayed toxicity studies have confirmed safe consumption of the
jellyfish. This study has clearly satiated the white type jellyfish consumption is safe and do not show adverse or delay
toxicity effect on biological aspects of the host
Wound healing ability of white type edible jellyfish Lobonema smithii in white rats
No full textWhite type edible jellyfish, Lobonema smithii were desalted, dried and extracted to formulate for oral consumption in white rats in wound healing study. Prior to that it was subjected to toxicity screening and tested for antioxidant activity. Methanolic and cold acetone protein precipitation extraction method was done to obtain methanol crude extract and crude protein extract
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
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
