Bone regeneration of the maxillofacial region through the use of mesenchymal cells obtained by a filtration process of the adipose tissue
No full textIn this work, the authors will discuss about a new protocol and rapid alternative to isolate the mesenchymal stromal cells from the stromal vascular fraction, without the use of collagenase, to regenerate the bone tissue in the maxillo-facial region. This method employs a device that allows the isolation and concentration of stromal vascular fraction by means of lipoaspirates, which separate the lipid component and fragments of the extracellular matrix. The innovative element consists in using a filtration device instead of a centrifuging device to separate the different components. The purpose of this work was to illustrate the results obtained with the above-mentioned method in a series of 8 patients suffering from cystic neoformations maxillary or mandibular
Intra- and extraoral implantology and anaplastology: clinical and instrumental evaluation to 7 years
No full textaim. The aim of this work was to evaluate the follow-up of patients treated 7 years after the application of the implant, focusing on the following specific issues: the quality of osseointegration and the presence of adverse reactions, including views from a radiological point of view, the status of the implant and the impact of its success on the quality of life of the patient.
Methods. From January 2002 to December 2009, in the Epithesis Center of Sant’Andrea Hospital, 65 surgical patients (31 women and 34 men, mean age 44 years) were treated. This study includes only those with control at 7 years for a total of 12 patients including 7 women and 5 men with a mean age of 43 years. The diagnostic and therapeutic procedures were standard for all patients.
Results. With regard to the postoperative clinical control 57 patients had no detectable adverse skin reaction, 3 patients had mild skin redness, inflammatory exudate was present in 1 patient, and inflammation became severe in 1 other patient. Postoperative radiological assessment at 6 months showed no signs of osseointegration in 197 facilities out of 198 (98.9%).
Conclusion. Epitheses are an important alternative to conventional reconstructive surgery for patients with craniofacial deficits. Using implant osseointegration could solve the problems caused by using adhesives and the presence of phenomena of irritation to the skin in contact with such substances, greatly improving the quality of life of patients

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
