Herrero (2013) Neuropathology and Applied Neurobiology39, 132143 Evidence of oligodendrogliosis in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced Parkinsonism Aims: Mice and nonhuman primates administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) represent elective experimental models of Parkinsonism, in which degeneration of the nigrostriatal dopaminergic pathway is associated with prominent neuroinflammation, characterized by activated microglia and astrocytes in both substantia nigra (SN) and striatum. To date, it is unknown whether oligodendrocytes play a role in these events. Methods: We performed a detailed qualitative and quantitative analysis of oligodendrocyte-associated changes induced by acute and chronic MPTP treatment, in the SN and striatum of mice and macaques respectively. Oligodendrocytes were immunolabelled by cell-specific markers and analysed by confocal microscopy. Results: In both experimental models, MPTP treatment induces an increase in oligodendrocyte cell number and average size, as well as in the total area occupied by this cell type per tissue section, accompanied by evident morphological changes. This multifaceted array of changes, herein referred to as oligodendrogliosis, significantly correlates with the reduction in the level of dopaminergic innervation to the striatum. Conclusions: This event, associated with early damage of the dopaminergic neurone axons and of the complex striatal circuits of which they are part, may result in an important, although neglected, aspect in the onset and progression of Parkinsonism

Epoxidation of multi-walled carbon nanotubes by organocatalytic oxidation
No full textEven though many functionalization methodologies for covalent modification of carbon nanotubes (CNTs) have been proposed, mild but effective approaches are still needed. Here we describe the epoxidation of multi-walled carbon nanotubes (MWCNTs) with dioxirane for an environmentally friendly oxidation process with an organocatalyst. Thank to the choice of dioxiranes (accessible and easy to handle and to store), multiple oxidation cycles could be performed on the same sample, thus allowing for a final improvement in the degree of oxidation at the CNT sidewall. The obtained derivatives were then used as electrophilic platforms for successive modification with an amine, with a high degree of functionalization (about 750 μmol?g-1 from TGA analysis) being obtained. An efficient method for the epoxidation of multi-walled carbon nanotubes (MWCNTs) is proposed. It leads to the production of materials that can be easily further functionalized by nucleophiles. Complete chemical (TGA, FTIR, XPS, Raman) and morphological (TEM) characterization of the materials has revealed a high degree of functionalization

L'Università come cantiere di lettura e progetto del territorio.
No full textIl contributo riflette sul ruolo del Campus di Cesena (FC) dell’Università di Bologna, Dipartimento di Architettura e in particolare del Laboratorio CARTA – Città Ambiente Reti Territorio Azioni rispetto alla volontà di rendere l’Università un nodo locale nella rete della conoscenza globale e capace di attivare politiche innovative sul territorio. In un momento in cui le disparità del nostro paese si sono moltiplicate, intaccando anche territori generalmente considerati forti, anche l’università è chiamata a ridefinire il proprio ruolo costruendo sinergie nuove nel e per il territorio. Questo è quello che il Laboratorio fa ormai da qualche anno nel territorio di Forlì-Cesena, coinvolgendo studenti, amministratori e attori presenti sul territorio nella costruzione di politiche e pratiche innovative condivise.The contribution reflects on the role of the University of Bologna, Department of Architecture in Cesena (FC) Campus and in particular of the CARTA Laboratory - Città Ambiente Reti Territorio Azioni with respect to the desire to turn Universities into local nodes in the global knowledge network and capable of activating innovative policies in the territory. At a time when the disparities in our country have multiplied, eroding territories generally considered strong, the University is called upon to redefine its role by building new synergies in and for the territory. This is what the Laboratory has been doing for some years now in the Forlì-Cesena area, involving students, administrators and actors in the area in the construction of shared innovative policies and practices
Guido Crepax – Valentina – The Shape of Her Time
Get PDFThe paper will focus on the analysis of Guido Crepax revolutionary comic book character Valentina that belongs to the golden age of the Italian comic-book genre fumetto. The aim is to explore whether Guido Crepax Valentina character was a "living doll" filling male fantasies of her creator or she was a woman empowered by her author struggling for many of the values of the women's culture that feminists today are trying to introduce into the mainstream. It also addresses research questions that focus on comic books and gender and empowerment at the decade of sexual liberation.Through Valentina case study the present paper is going to study an approach on the concept of woman in comics, and touch the border of female empowerment issue in contemporary world taking in consideration that her revolutionary strong and independent figure was born in a society where women have been frequently viewed as passive and represented as inferior to men and where questions of sexuality were considered taboo. Despite the fact that she angered some feminists by the way she was portrayed as an object of male gaze or a damsel in distress, there is nothing anti-feminist about Valentina. The aim here is to uncover feminist themes in the stories of Valentina and to explore what empowered her and made her a contemporary icon of style and symbol of liberated women
