Fecal Metaproteomics as a Tool to Monitor Functional Modifications Induced in the Gut Microbiota by Ketogenic Diet: A Case Study
Metaproteomics is a valuable approach to characterize the biological functions involved in the gut microbiota (GM) response to dietary interventions. Ketogenic diets (KDs) are very effective in controlling seizure severity and frequency in drug-resistant epilepsy (DRE) and in the weight loss management in obese/overweight individuals. This case study provides proof of concept for the suitability of metaproteomics to monitor changes in taxonomic and functional GM features in an individual on a short-term very low-calorie ketogenic diet (VLCKD, 4 weeks), followed by a low-calorie diet (LCD). A marked increase in Akkermansia and Pseudomonadota was observed during VLCKD and reversed after the partial reintroduction of carbohydrates (LCD), in agreement with the results of previous metagenomic studies. In functional terms, the relative increase in Akkermansia was associated with an increased production of proteins involved in response to stress and biosynthesis of gamma-aminobutyric acid. In addition, VLCKD caused a relative increase in enzymes involved in the synthesis of the beta-ketoacid acetoacetate and of the ketogenic amino acid leucine. Our data support the potential of fecal metaproteomics to investigate the GM-dependent effect of KD as a therapeutic option in obese/overweight individuals and DRE patients

Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Solid pseudopapillary tumor of the pancreas in children: Report of a case and review of the literature
Solid pseudopapillary tumor (SPT) of the pancreas is an infrequent neoplasm of low malignant potential, first described by Frantz in 1933 and representing less than 3% of all exocrine tumors. SPT is rare in children, accounting for 6% of all cases and shows different clinical features compared with adults. Here, a pediatric case is reported and a review of the Literature is provided. A 15-year-old girl with a 12 × 14 × 10 cm solid mass growing from the tail and the body of the pancreas, involving spleen, left adrenal gland and kidney, stomach and some bowel loops, was referred for surgical treatment. A distal pancreasectomy with splenectomy was performed. Histopathological examination revealed that the tumor was a 14-cm well-circumscribed solid mass, with pseudopapillary cell architecture, showing strong cellular immunoreactivity for alpha-1 antitrypsin, vimentin, neurone-specific enolase, progesterone receptors and in part to CD10 and CAM 5.2, but not to sinaptofisin and chromogranin. A 24-month post-surgical follow-up after successful surgical resection showed no evidence of recurrent disease. SPT shows different clinical features in childhood. High survival rates can be achieved in most cases, warranting aggressive treatments even in metastatic disease. © 2010 Springer-Verlag
Variations on the Author
“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
We 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
How Can We Renew and Make Villages More Attractive Thanks to a New Aesthetical Image? The Case Of Monteclana, in The Municipality of Nave (Brescia, Italy)
This essay presents the work carried out by the University of Brescia which got involved with the Municipality of Nave (Brescia) in 2014 to deal with the particular situation of Monteclana. Its position on the border of the town, outside the main route, the lack of buildings maintenance, the lack of public services and elements with appeal don’t allow for any other prospects apart from the progressive abandonment and the decrease of possibilities to bring it back to an attractive place to live and work in. The University of Brescia has proposed an operating solution to improve the aesthetic image of Monteclana. On the basis of an image, respectful of its preexistence, recognizable and shared with the citizens, the urban planning tools for
the historical centre have been completed by guide lines concerning the external structures. Streamlined procedures have been established to involve more citizens in investing in the maintenance of their property
