La gastrite eosinofilica nel cane: descrizione di 4 casi clinici.
Full text linkLa gastrite eosinofilica nel cane rappresenta
una condizione patologica rara. Nei soggetti
colpiti è possibile evidenziare eosinofilia periferica,
ma la diagnosi definitiva si basa sul riscontro
di infiltrazione eosinofilica a livello della
mucosa gastrica. Lo scopo del presente lavoro
è descrivere 4 casi di gastrite eosinofilica nel
cane diagnosticati in un periodo di 5 anni. Per
tutti i soggetti viene riportato il quadro clinico,
l’aspetto endoscopico ed il follow-up. Dalle valutazioni
fatte si osserva che la gastrite eosinofilica
è una patologia grave, in cui sia la presentazione
clinica che la valutazione ecografica ed
endoscopica possono far sospettare una patologia
di natura neoplastica; la terapia mirata, instaurata
dopo una diagnosi istologica, permette
una rapida e duratura risoluzione della sintomatologia
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
The swab-sampled dry fecal cytology in healthy dogs and in dogs with acute and chronic diarrhea: A pilot study
Full text linkDry-mount fecal cytology is a little explored procedure that is potentially useful for dogs with gastrointestinal diseases. This study describes fecal cytology using swab sampling in healthy dogs (HD) and in dogs with acute and chronic diarrhea. Forty HD, 40 dogs with acute diarrhea (AD; diarrhea < 5 days) and 40 dogs with chronic diarrhea (CD; diarrhea > 3 weeks) were also enrolled. Sixteen different cytological features were scored for each fecal sample. Twenty HD were used to establish normal reference range for each cytological feature. Exact tests were used to evaluate associations between the three groups. The presence of red blood cells, cocci bacterial monomorphism and spore-forming bacteria were significantly higher in AD than the HD. Neutrophils, lymphocytes and macrophages were significantly higher in AD and CD groups compared to HD. Plasma cells were significantly higher in CD and the HD and AD groups. Bacterial phagocytosis was significantly higher in AD group than CD and HD. In conclusion, swab-sampled fecal cytology, as a cheap and feasible procedure, can be a useful diagnostic and monitoring technique. Although, our pilot study results showed differences between HD and enteropathic dogs, further investigations are necessary
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
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
