Residui fiscali regionali e riforma federalista. Quanto residuerà delle politiche regionali e redistributive?

This paper criticizes the idea to conceive the fiscal federalist reform in Italy as a tool to empower central-northern regions to retain resources otherwise wasted in the South. We argue that such a view muddles up efficiency and redistribution issues, thus threatening the legitimate inter-regional fiscal flows. To dispute the thesis of excessive transfers to Mezzogiorno regions, we first show that the regional distribution of (both current and capital) government expenditure has systematically penalized the South in the last 15 years. Secondly, for the years 2004-2006, we calculate «benchmark» regional fiscal residua, consistent with the progressive Italian personal taxation (IRPEF), and the announced targets of regional policies (45% of total capital government expenditure to be made in the South). For most centre-northern regions, the actual residua turn out to be lower than the «benchmark» ones

Non-state nations: Structure, rescaling, and the role of territorial policy communities, illustrated by the cases of Wales and Sardinia

This paper explores the role of non-state nations’ identity and agency with regard to relations with their host nation states. The particular focus here is on the means by which such regions might express their individuality. To this end, we employ a comparative case study analysis of two non-state nations with a range of differing yet in other ways similar qualities – namely Wales (UK) and Sardinia (Italy). We suggest that this is a valuable exercise, allowing as it does for the exploring of evidence ‘on the ground’ of the processes involved. The conceptual rationale for the paper is provided by new regionalism – regions as actors beyond the nation state. Following this, the idea of the ‘territorial policy community’ is presented as a point of departure, with the scope of the paper being to develop a diachronic framework for regional change. Given the focus on identity and interest articulation, the role of regional political parties is a particular subject of the empirical investigation, with non-state nations and nation states linked by opportunistic relationships based on political and electoral support. We then consider what this might mean with regard to the capacity of non-state nations to build on the past to successfully negotiate future policy-making agendas. Finally, we reflect on the limitations of the study, and consider the implications of its findings for further research agendas

Medium-term culture of normal human oral mucosa: a novel three-dimensional model to study the effectiveness of drugs administration.

Tissue-engineered oral mucosal equivalents have been developed for in vitro studies for a few years now. However, the usefulness of currently available models is still limited by many factors, mainly the lack of a physiological extracellular matrix (ECM) and the use of cell populations that do not reflect the properly differentiated cytotypes of the mucosa of the oral cavity. For this reason, we have developed a novel three-dimensional culture model reflecting the normal architecture of the human oral mucosa, with the main aim of creating a better in vitro model where to test cellular responses to drugs administration. This novel 3D cell culture model (3D outgrowth) was set up using an artificial extracellular matrix (MatrigelTM), allowing the interactions required for proper differentiation of the various citotypes which form the mucosal layer. Biopsies of human oral mucosa, in fragments of about 0.5 mm3, were placed onto 6.5mm Transwells, covered with MatrigelTM and grown in a specific culture medium. A gradual formation of an architectural structure similar to that of the in vivo oral mucosa was observed. Transmission electron and confocal microscopy were employed to characterize the newly developed model: the cell components (keratinocytes and fibroblasts) differentiated properly within the outgrowth and reconstituted, in vitro, the physiological structure of the human oral mucosa, including a stratified non-keratinized squamous layer composed of four different layers, a proper basal membrane and a lamina propria where fibroblasts produce ECM. Moreover, keratinocytes expressed CK5, CK13, CK19 and E-cadherin, whereas fibroblasts expressed collagen type I and IV, laminin and fibronectin. 3D outgrowths could be considered a valid alternative to animal models, and provide useful information for researchers interested in studying the responses of the human oral mucosa to locally delivered drugs or other exogenous treatments

Tuberculosis chemotherapy: current drug delivery approaches

Tuberculosis is a leading killer of young adults worldwide and the global scourge of multi-drug resistant tuberculosis is reaching epidemic proportions. It is endemic in most developing countries and resurgent in developed and developing countries with high rates of human immunodeficiency virus infection. This article reviews the current situation in terms of drug delivery approaches for tuberculosis chemotherapy. A number of novel implant-, microparticulate-, and various other carrier-based drug delivery systems incorporating the principal anti-tuberculosis agents have been fabricated that either target the site of tuberculosis infection or reduce the dosing frequency with the aim of improving patient outcomes. These developments in drug delivery represent attractive options with significant merit, however, there is a requisite to manufacture an oral system, which directly addresses issues of unacceptable rifampicin bioavailability in fixed-dose combinations. This is fostered by the need to deliver medications to patients more efficiently and with fewer side effects, especially in developing countries. The fabrication of a polymeric once-daily oral multiparticulate fixed-dose combination of the principal anti-tuberculosis drugs, which attains segregated delivery of rifampicin and isoniazid for improved rifampicin bioavailability, could be a step in the right direction in addressing issues of treatment failure due to patient non-compliance
