Fishing new lives and minds in Italian and Maltese cinema: Tornando a casa and Simshar
No full textThe issues facing migrants and fishermen are at the core of Vincenzo Marra's Tornando a casa (Sailing Home) (2002) (Italy) and Rebecca Cremona's Simshar(2014) (Malta). Both films are shot primarily in the southern Mediterranean Sea and, although they feature similar life dramas and hazardous rescues, they are directed according to different aesthetic principles. While Simshar exhibits the highly emotional tones of a tragedy and a predictable ending, Sailing Home uses a prosaic style and offers a ground-breaking denouement. Inspired by a true story, Cremona's film helps reinforce concepts of 'Malteseness' while Marra's negotiates identity concerns, regardless of the protagonist's nationality. The Mediterranean Sea thus becomes the backdrop to unpredictable encounters that allow the promise of new friendships and can even change human destiny. The objective of this article is to draw out an iconographic and thematic comparison between these two films, arguing that they provide deep insight into current tragedies in a documentary-like, yet highly artistic way

Production of Injectable Marine Collagen-Based Hydrogel for the Maintenance of Differentiated Chondrocytes in Tissue Engineering Applications
Full text linkCartilage is an avascular tissue with limited ability of self-repair. The use of autologous chondrocyte transplants represent an effective strategy for cell regeneration; however, preserving the differentiated state, which ensures the ability to regenerate damaged cartilage, represents the main challenge during in vitro culturing. For this purpose, we produced an injectable marine collagen-based hydrogel, by mixing native collagen from the jellyfish Rhizostoma pulmo with hydroxy-phenyl-propionic acid (HPA)-functionalized marine gelatin. This biocompatible hydrogel formulation, due to the ability of enzymatically reticulate using horseradish peroxidase (HPR) and H2O2, gives the possibility of trap cells inside, in the absence of cytotoxic effects, during the cross-linking process. Moreover, it enables the modulation of the hydrogel stiffness merely varying the concentration of H2O2 without changes in the concentration of polymer precursors. The maintenance of differentiated chondrocytes in culture was then evaluated via morphological analysis of cell phenotype, GAG production and cytoskeleton organization. Additionally, gene expression profiling of differentiation/dedifferentiation markers provided evidence for the promotion of the chondrogenic gene expression program. This, combined with the biochemical properties of marine collagen, represents a promising strategy for maintaining in vitro the cellular phenotype in the aim of the use of autologous chondrocytes in regenerative medicine practices
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
