Effects of exposure of mytilus galloprovincialis to ni(ii), cu(ii) and cd(ii) on accumulation and on glutathione s-transferase expression level on gonads and gills
hsp70 AS New Cadmium Bioaccumulation Marker to prevent the risks of Mussels Consumption in Human Nutrition
The consumption of seafood has increased in recent years, especially in coastal
regions. The consumption of mussels provides proteins, essential minerals and vitamins,
and thus, some protection from certain diseases but the risks and benefits of their
consumption are still hard to assess because of the metals bioaccumulated from the
marine environment, with their toxicity. Mussels accumulate a wide range of metals,
included cadmium, in their soft tissue. Cadmium is a heavy metal particularly hazardous
for human health and is an important pollutant in estuarine and coastal environments.
Thus, the determination of the concentrations of cadmium in mussels is essential because
of their usage as seafood and the potential adverse effects of their consumption on
human health. In order to identify a quick cadmium bioaccumulation marker usable in
monitoring programs, we analyzed the metal content in Mytilus galloprovincialis gill
tissues and its relationship with hsp70 expression levels after a laboratory exposure for
24 h to 1,5; 5 and 10 μM CdCl2 in artificial sea water. Inductively coupled plasma-mass
spectrometry showed that cadmium content increased in gills tissues in an exposure
dose-dependent fashion. RT-qPCR, showed that Cd exposure induced hsp70 increase
resulting in 3,1;10 and 12 fold at 1,5; 5, 10 μM, respectively in comparison with unexposed
mussels. Finally, hsp70 expression levels correlated with the amount of bioaccumulated
cadmium in gill tissue, indicating hsp70 as a potential marker, even if not univocally, of
significative cadmium bioaccumulation usable in environmental monitoring programs
and for seafood safety

Full Digital Workflow for Prosthetic Full-Arch Immediate Loading Rehabilitation Using OT-Bridge System: A Case Report
Nowadays, digital technologies have brought very important advancements in clinical prosthetic dentistry. However, a full digital workflow is still considered to be challenging in the management of full-arch implant cases with immediate prosthetic loading. The aim of this case report is to show a full-digital workflow for the fabrication of an implant-prosthetic fixed provisional prosthesis for immediate loading on seven implants in the upper maxilla. The static guided implant surgery and the OT Bridge prosthetic system were used to rehabilitate the patient. In this way, the combination of a well-known surgical technique with a peculiar prosthetic system that allows for a certain degree of tolerance resulted in it being useful for full-arch immediate loading. Future research and studies are necessary to prove the reliability of this full-digital protocol
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
I barbieri maestri di musica
Il testo illustra le pratiche musicali legate al contesto dei barbieri siciliani, seguendo una documentazione che va dalla fine del Quattrocento fino ai nostri giorni, attraverso testimonianze rilevate dall'autore in numerosi centri della Sicilia. Le musiche in questione sono eseguite con strumenti a corda e il repertorio contiene soprattutto brani da ballo e canzonette
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
