Can trans resveratrol plus d-chiro-inositol and myo-inositol improve maternal metabolic profile in overweight pregnant patients?
Full text linkObjective. To investigate the effect of trans-resveratrol from Polygonum cuspidatum/magnesium hydroxide complex, trademark Revifast®, plus D-chiro-inositol (DCI) and Myo-inositol (MI) during spontaneous pregnancies in overweight patients in a pilot study. Study design. A one-year, prospective, randomized, doubleblinded, placebo-controlled single center clinical study was carried out on overweight pregnant women. 110 patients were randomized in 3 groups to receive: Revifast® with DCI/MI (group I), DCI/MI alone (group II) or control group (group III) for 30 and 60 days. The main outcomes were to explore the lipid profile (total cholesterol, LDL, HDL, TG) and glucose levels, after 30 and 60 days of therapy. Results. No difference in systolic and diastolic parameters among 3 groups during study. All blood chemistry parameters improved compared to placebo at 30 days already, but significantly to 60 days, respect placebo. By comparing the two treatment groups, group I demonstrates significantly improved lipid and glucose parameters than group II, which are at 30 to 60 days of treatment. Conclusion. The supplementation of Trans-resveratrol, Revifast® in addition to DCI/MI in overweight pregnant woman with an elevated fasting glucose improves glucose levels, Total Cholesterol, LDL and TG
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

Laminin and Collagen IV: Two Polypeptides as Marker of Dystocic Labor
No full textCollagen IV and Laminin are localized in cells and tissue of numerous human organs including the uterus, where these polypeptides control either age changes, or uterus growth in pregnancy, or ripening and dilatation in labor. Authors examined the polypeptides distribution of collagen IV and Laminin in the human pregnant uterus, in normal and dystocic labor, to clarify their physiologic role, by distribution and/or their changes in prolonged dystocic labor. We collected lower uterine segment (LUS) fragments during cesarean section (CS); these biopsies were treated with basic morphological staining for the observation of microscopic- anatomic details. Other samples were processed with immunohistochemical staining for collagen IV and for membrane bound Laminin. All morphological and immunochemical results were analyzed with quantitative analysis of images and statistical analysis of data. Both Collagen IV and Laminin show changes in the pregnant uterus before 4 hours of full cervical dilatation in patients after 4 hours. All the three types of the human uterine cells, mucosal, submucosal and smooth muscular cells, are more reduced in LUS after 4 hours of cervical dilatation in dystocic labor. The connective tissues (including fibroblast) show the most evident changes in the dystocic LUS, collagen IV and laminin changes during cervical dilatation in prolonged dystocic labor, with a decreased elasticity with increased roughness and dryness. The LUS anatomical modifications during labor can be the cause of pathological changes in protracted dystocic labor. In the dystocic labor that lasts more than 4 hours from the complete cervical ripening and dilatation, the laminin and collagen IV concentration reduces in the LUS tissue. In dystocic labor, delivery should be completed before the 3 hours of full dilation, to avoid a reduction of laminin and collagen IV and a worsening of LUS healing for the next pregnancy
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
