How Close Can We Look Into the Fetus by New Applications of Three‐Dimensional Ultrasound: The Fetal Eye
No full textThree- and four-dimensional ultrasound technology has become essential in the field of prenatal diagnosis. Recent exponential improvements in ultrasound machines and 3D technology have produced high-definition, high-resolution images, and new rendering modalities have opened up novel perspectives for exploring fetal anatomy. This raises the questions about how detailed our examination of fetal anatomy can be and what clinical applications remain undiscovered. This short article aims to provide academic references focusing specifically on examining minute structures within the fetal eye using advanced 3D ultrasound technology
Ladylift® non-ablative laser technology for the treatment of menopausal vestibulodynia and genitourinary syndrome
Get PDFIntroduction: Genitourinary syndrome of menopause (GSM) affects up to 48% of pre-menopause women and up to 90% of menopausal women. Many menopausal women with dyspareunia have significant vestibular tenderness due to oestrogen deficiency, which increases the density of sensory nerve fibres in the vulva and the vagina. For this reason, GSM is recognized as one of the causes of provoked vestibulodynia. Few therapies have proven to be effective for provoked vestibulodynia. Many studies have shown the efficacy of laser CO2 therapy, proving its cost-effectiveness and safety for vaginal health.Material and methods: In this article we tested a new non-ablative solid-state laser: Ladylift (R). The main difference between Ladylift (R) and other laser technologies is the use of a non-ablative laser wavelength of 1470 nm, without causing ablative thermal injury on the surface of the mucosa. We enrolled 18 post-menopausal women presenting to a private clinic with GSM symptoms and provoked vulvodynia.Results: The treatment protocol consists of 4 sessions of laser, 2 weeks apart, of the duration of 4 minutes. Benefits to menopause symptoms, reported with a numeric rating scale, and to epithelium trophism reported with the vaginal health index were apparent since the first session. Patients undergoing laser therapy have had evident benefit both from the point of view of pain and from that of vaginal health. Conclusions: All the women tolerated the therapy well without any adverse effects. However, the beneficial effect tended to gradually decrease over time, suggesting the need to perform more therapy sessions
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
