Ethic nutritional supplementation: An indispensable instrument in plastic dermatology
No full textAuthors refer about the best characteristics of an integrative nutritional supplementation to improve skin health and reduce oxidative and degenerative phenomena inside the skin. In this review all the most relevant and scientifically proven molecules are considered and the main biochemical and physiological properties are described. Authors paid attention to the role of protein glycation in the onset of some signs and degenerative pathologies such as eye cataract, skin dystrophy and ulcer, Alzheimer disease and many others. Into this context L-Carnosine, Lipoic acid, NAC, Resveratrol and other functional molecules are described and characterized under the point of view of effective dosage, bioavailability and physiological effect. All the concepts exposed complain with the most relevant scientific literature available
Resveratrol: A review of pharmacological and health-promoting properties
No full textResveratrol is a stylbenic poliphenolic molecule extracted from the skin of red grape and Polygonum cuspidatum which exerts many biological activity in human health maintenance. Resveratrol is one of the most effective phyestrogen in nature and is capable to reduce effectively signs and symptoms of menopausa such as hot flash and skin degradation. Resveratrol has been proven to be really effective in the prevention of several cardiovascular diseases reducing ateromatic lesions and lowering LDL cholesterol. Many biochemical and clinical investigations clarified that Resveratrol is capable to inhibit cancer cells growth activating specific enzymes (caspases) inducing apoptosis. This paper describes Resveratrol pharmacology and take into account the most recent scientific investigations and data regarding its application in medicine and health care
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
Direct TMJ injuries
No full textNormal anatomy and function of temporomandibular joint (TMJ) may be altered by direct traumatic injuries of joint tissues or of adjacent bones such as the lower jaw. Both cases are known as "direct trauma" to differentiate them from "indirect trauma" acting on the TMJ without contact, such as the TMJ whiplash. Nature and direction of traumatic forces, type of acute lesions (i.e. fractures and/or contusions), accuracy of diagnosis and correctness of therapeutic approach will influence the onset of different temporomandibular disorders (TMD), ranging from muscle disorders or disc displacement with reduction to severe ankylosis. The dentist acting as expert witness has to assess trauma-related TMD symptoms: a correct evaluation must be based on a complete articular and muscular assessment, must take into account for the existing literature, and must follow a correct step-by-step sequence. This approach allows to discriminate between trauma-related and non-related lesions, through the identification of pre-existing pathologies or risk factors. The final report will provide the medical legal basis of a complete evaluation
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
