A preliminary study on behavioral aspects in dogs with idiopathic epilepsy
No full textIdiopathic epilepsy is considered the most common chronic neurological disease in dogs, and there is an increasing awareness regarding the behavioral impact of this disease on canine patients. This work aims at showing the potential differences in the behavioral profile and affective state of epileptic and not epileptic dogs, through the Canine Behavioral Assessment and Research Questionnaire (CBARQ) and the judgement bias test (JBT). Thirty dogs were involved: 15 with Idiopathic epilepsy (IE), 10 under treatment with phenobarbital, five not treated; 15 controls. For each dog, the owner completed the CBARQ. Twenty-seven dogs underwent training for the JBT. All data were statistically analyzed. Dogs with IE got a strong tendency for higher scores for excitability (U=70.0; median: 2.3 versus 1.8; p=0.077) and attention-seeking behaviors (U=66.0; median: 2.7 versus 2.2; p=0.053). Moreover, epileptic dogs were less likely to pass the training phase (58.3% versus 86.7%; X2=2.8; p=0.093), but those who passed it completed the JBT similarly to non-epileptic dogs (U=33.0; p=0.618). Although further studies are needed, epileptic dogs in this study showed differences in excitability, anxiety, and trainability compared to control dogs, suggesting a trend for behavioral aspects to be better explored. Being able to recognize and manage them could have a positive impact on the welfare of these animals
Adiponectin system in the skin of the obese dog: a comparative study
No full textIntroduction: Adipokines regulate skin functions under physiological and pathological conditions. Obesity influences on a plethora of associated diseases including skin dermatological disorders. However, adipokines are poorly investigated in the skin of obese animals. This work aims to study the localization and expression of adiponectin (ADIPOQ), and its related receptors (ADIPOR1 and ADIPOR2), in the skin comparing obese and normal-weight dogs.
Materials and Methods: The study was carried out on of ten obese (body condition score, BCS ≥7/9) and ten normal-weight (BCS of 4–5/9) adult dogs. Skin biopsies were collected from the ventral region and used to perform Real-time PCR and immunohistochemistry.
Results: ADIPOQ and ADIPOR2 immunostaining was observed in the sweat and sebaceous glands, in the adipose tissue extending among follicular clusters, in the endothelium and some connective cells. In addition, ADIPOR1 and ADIPOR2 were observed in the epidermis, in the hair
follicles, in the sweat and sebaceous glands. Significant expression differences were observed for ADIPOQ and ADIPOR2 transcripts that were 5.4-fold (p<0.01) and 2.3-fold less (p <0.01) respectively, in obese than in normal-weight dogs while no difference was observed for
ADIPOR1.
Conclusion: ADIPOQ and ADIPOR2 expression in the skin appear negatively correlated with obesity. These findings evidence that the ADIPOQ system changes in the obese dog skin and suggest that ADIPOR2 regulates the ADIPOQ effect on the skin. This study opens interesting
questions on the modifications of adipokines in the skin of obese animals.
The experimental procedures were approved by the Ethical Animal Care and Use Committee (n.PG/2017/0099607) of the University of Naples Federico II
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
