S.E.M. study I: Gastric and duodenal lesions induced by non-steroidal anti-inflammatory drugs (aspirin, piroxicam) in man
No full textA scanning electron microscopy (SEM) study was performed on the gastric and duodenal mucosa of 14 patients treated with Aspirin or Piroxicam. Six patients with normal mucosal morphology were treated with either 1.5 g/day of Aspirin (3 patients) or 20 mg/day of Piroxicam (3 patients) for one month. In addition, 8 rheumatic patients were treated with a similar dose of Aspirin (4 patients) or Piroxicam (4 patients) for at least 4 months. SEM was used to evaluate the following parameters: mucosal structure, cellular exfoliation and anisocytosis, alteration of the microvilli (blebs). The mucosa showed various aspects of alterations ranging from minimal changes (microvillar alteration) to a completely subverted structure both in the stomach and in the duodenum. Mucosal changes, both on the edge of the macroscopic lesions and at a distance from these, were visible with SEM even when endoscopy was normal. Piroxicam appeared slightly less damaging than Aspirin, and no difference was observed between short-term and long-term treated patients, either with Aspirin or with Piroxicam
S.E.M. study II. Protective effect of ranitidine against gastric and duodenal lesions induced by non-steroidal anti-inflammatory drugs
No full textThe effect of Ranitidine on the gastric and duodenal lesions induced by Aspirin or Piroxicam was studied by scanning electron microscopy (SEM). Twelve patients were entered into the study. The first group consisted of 6 patients with normal basic morphology, of which 3 were treated with 1.5 g of Aspirin and Ranitidine 300 mg/day, and 3 with 20 mg of Piroxicam and Ranitidine 300 mg/day, for one month. The second group was composed of 6 rheumatic patients, 3 of which took 1.5 g of Aspirin and the other 3 received 20 mg of Piroxicam per day for at least four months. Ranitidine (300 mg/day) was then administered concomitantly for one month to all these 6 patients. Overall, Ranitidine appeared to have a positive effect in preventing the development of gastroduodenal lesions induced by these anti-inflammatory drugs in the first group of patients. No differences were observed in the ability of Ranitidine to promote the healing of lesions induced by chronic treatment. Ranitidine, however, appeared to be more effective in preventing lesions induced by Aspirin rather than those induced by Piroxicam

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
La storia dell'integrazione europea: dai Trattati di Roma alla Facoltà "Roberto Ruffilli"
No full textLa storia dell’integrazione europea è nata proprio ed insieme all’avvio di quel processo politico che, innescato durante la seconda guerra mondiale, si è formalizzato a Roma nel 1957. Più interessante e complesso è invece cercare di comprendere quanto e in che modo sia cambiata la storia come disciplina e si sia adattata per accogliere e interpretare questa nuova realtà. Vari settori della storia contemporanea hanno interagito e tentato di spiegare il processo di integrazione europea e lentamente è nata una disciplina con caratteristiche proprie, ma che tuttora viene anche insegnata da storici di altri settori. Infatti, quando negli anni Novanta la storia dell’integrazione è arrivata nelle Facoltà di Scienze Politiche italiane, la Roberto Ruffilli compresa, erano pochi gli storici dell’integrazione nel nostro paese; la gran parte erano storici delle relazioni internazionali, dei partiti e movimenti politici, economici e alcuni storici contemporaneisti
