Biosilica

2012

Biomineralization, biosilicification in particular (i.e. the formation of biogenic silica, SiO(2)), has become an exciting source of inspiration for the development of novel bionic approaches following 'nature as model'. Siliceous sponges are unique among silica-forming organisms in their ability to catalyze silica formation using a specific enzyme termed silicatein. In this study, we review the present state of knowledge on silicatein-mediated 'biosilica' formation in marine demosponges, the involvement of further molecules in silica metabolism and their potential applications in nano-biotechnology and bio-medicine. While most forms of multicellular life have developed a calcium-based skel…

A Different Role of Taxation. From a One-Sided Taxation To a Circular Taxation

2020

The essay explores a possible different use of tax revenue, that is a perspective in which taxation is linked to a public choice in a circular way, thus determining a shift from the traditional “one-side taxation” process to a “circular taxation” process. Starting from the widely studied juridical phenomenon, known in Italy as regeneration of common spaces and goods or simply “regeneration”, and addressing the case of the regeneration of a brownfield, the Author argues that this phenomenon shows some common points with the so-called “circular economy”, since they are both inspired by the same principle of making resources usable in a circular context, exploiting already existing goods and r…

Zebrafish Fins as a Model System for Skeletal Human Studies

2007

Recent studies on the morphogenesis of the fins ofDanio rerio(zebrafish) during development and regeneration suggest that a number of inductive signals involved in the process are similar to some of those that affect bone and cartilage differentiation in mammals and humans. Akimenko et al. (2002) has shown that bone morphogenetic protein-2b (BMP2b) is involved in the induction of dermal bone differentiation during fin regeneration. Many other groups have also shown that molecules from the transforming growth factor-beta superfamily (TGFβ), including BMP2, are effective in promoting chondrogenesis and osteogenesisin vivoin higher vertebrates, including humans. In the present study, we review…

Cortical gene expression in spinal cord injury and repair: insight into the functional complexity of the neural regeneration program

2011

Traumatic spinal cord injury (SCI) results in the formation of a fibrous scar acting as a growth barrier for regenerating axons at the lesion site. We have previously shown (Klapka et al., 2005) that transient suppression of the inhibitory lesion scar in rat spinal cord leads to long distance axon regeneration, retrograde rescue of axotomized cortical motoneurons, and improvement of locomotor function. Here we applied a systemic approach to investigate for the first time specific and dynamic alterations in the cortical gene expression profile following both thoracic SCI and regeneration-promoting anti-scarring treatment (AST). In order to monitor cortical gene expression we carried out micr…

Relevance and Role of Contemporary Architecture Preservation—Assessing and Evaluating Architectural Heritage as a Contemporary Landscape: A Study Cas…

2023

Since WWII to the 2000s, numerous masters of contemporary architecture have contributed to the construction of new landscapes with their works; therefore, these places have become part of a changing landscape and of the multifaceted process of landscape generation. Nevertheless, during this fifty-year period, capitalism has led to the destruction of many existing landscapes, and the policies of protection and preservation have often entailed a process of musealization. In 2000, the European Landscape Convention adopted a new common-grounded definition of landscape, integrating a wide set of cultural approaches and disciplinary topics. Starting from the assumption that contemporary architect…

Cultura per chi? Pratiche artistiche, trasformazioni urbane e innovazione sociale nelle città postpandemiche

2022

In un’Italia fortemente compromessa dall'emergenza sanitaria, la crisi urbana che ne è scaturita ha posto in evidenza come la cultura, declinata attraverso processi e pratiche di produzione artistica e creativa, abbia offerto importanti occasioni di engagement ed empowerment, concorrendo alla costruzione di un welfare di comunità in risposta alle urgenze del presente. Lontano dall'idea di intrattenimento e divertissement, è sempre più chiaro come pratiche di innovazione culturale, sperimentando varie forme di azione e partecipazione, possano giocare un ruolo fondamentale nei processi di coesione sociale e costruzione di comunità, rappresentando in alcuni casi un antidoto all’inasprirsi dei …

Pat Barker’s Regeneration: Subverting the Masculinity of World War I Official Discourse

2014

Pat Barker’s Regeneration (1991) offers an imaginative deconstruction of the myth of the Great War as produced within British official patriotic rhetoric and in some of the best-known lyrics by Wilfred Owen (1893- 1918), who, together with Siegfried Sassoon (1886-1967), has always been celebrated as one of the leading War poets. If Owen’s poetry partly entails the apolitical sublimation of the devastating facts of war through the ambiguous sentiment of pity, in Barker’s novel any suppression of emotions is posited as artificial and counterbalanced by a thorough exploration of those contradictory aspects of the Great War which official discourses have tended to obscure: the homoerotic experi…
