Evaluation of ELIEDA test for immunodiagnosis of hydatid disease
No full textAn ELIEDA test for hydatidosis was evaluated with sera from preoperative, surgically-confirmed hydatidosis cases, postoperative hydatidosis patients, persons with other parasitic disease and healthy donors. ELIEDA was more sensitive than the counter-immunoelectrophoresis test based on the same positivity criterion and was equally specific for the immunodiagnosis of human hydatidosis. The procedure appears to be simple and rapid and merits consideration in that it determines specific classes of antibodies involved in the immune response which appear to be useful in following the evolution of hydatid cysts

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
Terapia antibiotica delle pneumopatie acute batteriche
No full textHaving discussed the various factors responsible for changes in the etiology of acute bacterial pulmonary diseases, the authors examine presently available chemoantibiotics for the treatment of these diseases. On the basis of general and personal experience they suggest different therapeutic patterns for the most widespread etiologie
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
Recenti acquisizioni nella diagnosi immunologica delle Malattie Infettive e Parassitarie
No full textIn the last years, remarkable advancements concerning the immunological diagnosis of infections and parasitic diseases have been made. We briefly review, also on the basis of our personal experience, the most recent immunological methods commonly employed for the diagnosis of viral, bacterial and parasitic diseases
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Malaria da Importazione
No full textWe describe a patient with Plasmodium vivax malaria whose first clinical signs appeared eight months after the exposure. It should be pointed out that the residence in an endemic area is of relevant importance for the diagnosis as well as the necessity of a correct chemoprophylaxis
THE THIN-LAYER IMMUNOASSAY (TIA) IN IMMUNODIAGNOSIS OF HUMAN HYDATIDOSIS. PRELIMINARY-OBSERVATIONS
No full textWe have applied a new test, the Thin Layer Immunoassay (TIA) to serodiagnosis of Hydatid disease and the results were compared with those obtained with ELISA. TIA has been shown to be highly sensitive and specific
