Probiotics for non-alcoholic fatty liver disease and/or steatohepatitis
Full text linkNon-alcoholic fatty liver disease comprises a spectrum of diseases ranging from simple steatosis to non-alcoholic steatohepatitis, fibrosis, and cirrhosis. Probiotics have been proposed as a treatment option because of their modulating effect on the gut flora that could influence the gut-liver axis.However, the lack of randomised clinical trials makes it impossible to support or refute probiotics for patients with non alcoholic fatty liver disease and non-alcoholic steatohepatitis
Antioxidant supplements for non-alcoholic fatty liver disease and/or steatohepatitis
Full text linkNon-alcoholic fatty liver disease (NAFLD) is characterised by fatty deposition in the hepatocytes of patients with minimal or no alcohol intake and without ther known cause. NAFLD include a wide spectrum of histologic abnormalities ranging from hepatic steatosis to non-alcoholic steatohepatitis (NASH), or even cirrhosis. Antioxidant supplements, therefore, could potentially protect cellular structures against oxidative stress and the resulting lipid peroxidation. There is insufficient data to either support or refute the use of antioxidant supplements for patients with NAFLD. It may be advisable to carry out large prospective randomised clinical trials on this topic
Bile acids for non-alcoholic fatty liver disease and/or steatohepatitis.
No full textNon-alcoholic fatty liver disease is a condition charactrerised by fatty deposition in the hepatocytes of patients with minimal or no alcohol intake. Some patients develop non alcoholic steatohepatitis. Bile acids may potentially protect cellular structures and may be of benefit in patients with non alcoholic fatty liver or steatohepatitis.Presently, there are insufficient data to support or refute the use of ursodeoxycholic acid for patients with non-alcoholic fatty liver or steatohepatitis. It may be advisable to carry out large randomised clinical trials on this topic
The perihepatic adipose tissue thichness: a non-invasive marker of NAFLD?
No full textSeveral non-invasive markers have been proposed to assess liver damage in NAFLD. We measured by ultrasound (US) the perihepatic adipose tsssue thickness (PATT), i.e. the thickness of the fat between the abdominal muscular layer and the hepatic surface, in addition to waist circumference, BMI, biochemistry and serum adipokines, to predict the severity of liver damage in NAFLD. In conclusion PATT and waist circumference could represent non- invasive markers predicting the severity of liver damage in NAFLD
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
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
