Background: Anorexia Nervosa (AN) is prevalent in modern
societies but is not well understood yet.
Aim: The aim of this study is to evaluate circulating levels of
Adiponectine (Apn) and the relationship between these levels
and anthropometric and metabolic parameters.
Materials and methods: The study included 40 women, 20
with AN (BMI 15Æ7 ± 2Æ1 kg m)2, age 30Æ2 ± 10Æ5 years), 12
restricter (BMI 14Æ9 ± 1Æ6 kgm)2) and 8 binge-purge subtype (BMI
18Æ3 ± 0Æ8 kg m)2), and 20 healthy controls (BMI 22Æ06 ± 0Æ93 kg
m)2, age 32Æ4 ± 4Æ4 years). Food intake was evaluated by a 5-day
24 hour dietary recall.
Results: Apn was higher (P < 0Æ001) in AN (36Æ84 ± 13Æ12 ng
mL)1) than controls (15Æ1 ± 3Æ0 ng mL)1) and (P = 0Æ004) in restricter
(41Æ8 ± 11Æ0 ng mL)1) than in binge-purge AN subtype
(22Æ1 ± 4Æ5 ng mL)1). Apn levels were negatively related with
BMI in total population (AN + C), without significance.
Total and LDL (Low Density Lipoprotein) Cholesterol levels
were higher (P < 0Æ05; P = 0Æ001) in AN (193Æ09 ± 39Æ86 mg
dL)1; 107Æ95 ± 27Æ75 mg dL)1) than C (166Æ09 ± 13Æ70 mg dL)1;
83Æ6 ± 15 mg dL)1), while Albumin was lower (P < 0Æ05) in
AN than C (4Æ40 ± 0Æ41 vs. 4Æ65 ± 0Æ57 g dL)1); no difference
between restricter and binge-purge subtype. Prealbumin and C
Somatomedine were similar in AN and C because of these
parameters rapidly change with changing of nutritional habits,
and the study’s patients were already included into nutritional
educational program: although their daily caloric intake was
lower than the recommended assumption levels of nutrients
(LARN, National Institute of Nutrition), the caloric division
between macronutrients was correct.
Conclusions: Increase of Apn in AN might be related to fat
mass reduction, in fact Apn progressively increase in losing
weight obese, or fat mass might exert negative feedback on Apn production, the severe emaciation in AN could inhibit
this feedback
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
