Hemorrhage in the Wirsung's duct caused by aneurysm of the splenic artery in chronic pancreatitis.
No full textTwo cases of haemorrhage from rupture of a splenic artery aneurysm into the pancreatic duct are reported. Both patients suffered from chronic pancreatitis; when haemorrhage appeared both patients experienced abdominal pain. In one patient the melaena was repetitive, in the other one--with a single episode of melaena - the endoscopy showed fresh blood near the papilla. In both patients ultrasonography and computerized tomography (CT) revealed a cystic mass in the pancreatic tail; CT scan also showed a clear contrast enhancement of these lesions after iodinated medium intravenous bolus. Coeliac arteriography confirmed the presence of two large saccular aneurysmal dilatation of the splenic artery. Both patients underwent a laparotomy: distal pancreatectomy with aneurysm resection and splenectomy were successfully performed

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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

Morphological and molecular features of apoptosis and its role in colorectal cancer prevention
No full textApoptosis is a form of cell suicide that is essential for the control of cell growth in multicellular organisms. Apoptosis has a very important biological significance in mammals, both during embryonic life and adulthood. Defects in the apoptosis machinery cause several human diseases, including cancer. The induction of apoptosis is now recognized as a major strategy for the treatment and prevention of cancer. Colorectal cancer is a leading cause of
cancer death, with the highest prevalence in North America, Europe, Australia, and New Zealand. Aim of the present article is to review the mechanism and biological significance of
apoptosis and highlight the efficacy of natural agents that target apoptosis in colo-rectal cancer prevention
