Morphological aspects of atherosclerosis lesion: past and present.
No full textAtherosclerosis is an inflammatory process disease that involves the artery wall and that is characterized by the progressive accumulation of lipids. The term arteriosclerosis has been created by Lobstein in 1833. Subsequently, during the 19th century, the contribution of Rokitansky and Virchow was important to elucidate the pathogenesis of arteriosclerosis and the morphologic aspects of the plaque. In the beginning of the 20th century, Aschoff was a leading proponent who regarded the morphologically different intimal lipid deposits of children and adults as early and late stages of one disease and he called them atherosis and atherosclerosis, respectively. The first classification of atherosclerosis was made by the World Health Organization (WHO) in 1958 and it consisted of the following sequence: fatty streak, atheroma, fibrous plaque and complicated lesions. In 1990s, thanks to much more sensitive techniques, the American Heart Association (AHA) proposed a new morphological classification based on eight lesion types designated by Roman numerals which indicate the usual sequence of lesion progression. Finally, Virmani et al. (2000) described a classification with the add of a specific plaque type, not recognized by the AHA classification, called "thin fibrous cap atheroma" which is more likely to rupture. The atherosclerotic process is characterized by typical ultrastructural changes that mainly involve the endothelial and smooth muscle cells. The morphological alterations of the endothelium are associated with dysfunctions leading to a proinflammatory and prothrombotic phenotype. This process seems to be due to turbulent blood flow and low fluid shear stress that normally occurs in particular regions of the vascular tree. Inflammation has a key role in the pathogenesis of atherosclerosis and it is supported by numerous factors such as modified LDL, hypertension, diabetes mellitus, free radicals and, in particular, by infectious agents such as Chlamydia pneumoniae

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
