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
Uveite intermedia associata a polineuropatia da virus di Epstein-Barr.
No full textIntroduction: Epstein -Barr Virus (EBV) can cause intraocular inflammation and in some cases, althoug occasionally, has been showed to be responsible for intermediate uveitis. Purpose of this study is to describe a peculiar of EBV vitritis associated with peripheral polyneuropathy. Case report: A 40 years old patient presented with long-standing bilateral intermediate uveitis resistant to steroid therapy and associated with peripheral polyneuropathy. Bilateral vitrectomy surgery was necessary. The search for viral DNA by PCR in the vitreous sample allowed to isolate high EBV title. Conclusions: We suggest that EBV might be responsible for both uveitis and neurological manifestations. Vitrectomy was necessary for the improvement of the inflammation and the visual prognosis and for a correct diagnosis. Key words: Epstein - Barr virus, intermediate uveitis, polyneuropathy, vitriti
Association between -308 G/A TNF- α polymorphism and appendicular skeletal muscle mass index as a marker of sarcopenia in normal weight obese syndrome
No full textBackground and Aim. Normal weight obese (NWO) syndrome is characterized by normal body mass index (BMI), but high amount of fat mass and reduced lean mass. We evaluated allelic frequency of the G/A -308 TNF-α polymorphism and prevalence of sarcopenia in NWO. Methods. We enrolled 120 Italian healthy women, distinguished into 3 groups: normal weight (NW); NWO, and preobese-obese (PreOB/OB) and evaluated anthropometric parameters, body composition by dual X-ray absorptiometry, blood tests, and genotyping of G/A -308 TNF-α polymorphism. Results. We found a positive association between sarcopenic obesity and -308 TNF-α polymorphism. All obese women were sarcopenic and were no carrier of mutation (G/G). Among all G/G, NWO showed significant differences in lean mass and total body lean mass (TBLean) with respect to NW and PreOB/OB (P < 0.001). Regarding appendicular skeletal muscle mass index values, 4.21% of NW were sarcopenic (50% G/G and 50% G/A); the same percentage was observed in NWO subjects (100% G/G). Moreover, 2.10% of PreOB/OB were sarcopenic and all were G/G. Conclusion. Our study suggests that TNF-α polymorphism contributes to sarcopenic obesity susceptibility, in association with body composition. This is the first study that shows the importance of TNF-α polymorphism to determine TBLean variation in NWO syndrome. © 2013 L. Di Renzo et al
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
Rosmarinic acid as potential anti-inflammatory agent
No full textRosmarinus officinalis L. (Lamiaceae), popularly known as rosemary, is used for food flavoring, and in folk medicine, as an antispasmodic, analgesic, anti-rheumatic, diuretic, and antiepileptic agent. Rosemary is an herb widely used in folk medicine, cosmetics, and phytotherapy and for flavoring of food products. Studies have focused on various biological activities of the secondary metabolites of this plant, such as rosmarinic acid, which have powerful antioxidant, hepato-protective, antimicrobial, anti-nociceptive, and anti-inflammatory properties
