FVG-Europa: ultima chiamata. Un "porto-regione" tra Mediterraneo e Centro Europa
No full textIl libro tratta di come trasformare una opportunità geografica in un concreto progetto territoriale. L’opportunità
consiste nel valorizzare la favorevole posizione geografica del Friuli Venezia Giulia – tra il Mediterraneo e
le regioni più produttive dell’area germanica – dal punto di vista dei commerci marittimi e terrestri. Cogliere tale opportunità, certificata in primo luogo dall’Unione Europea (con la recente approvazione, da
parte del Parlamento europeo, del Corridoio Adriatico-Baltico) e da grandi organizzazioni internazionali, potrebbe rilanciare profondamente un’economia regionale in forte declino.
Il libro indica puntualmente una strada ancora percorribile per raggiungere l’obiettivo fino a ora mancato: mettere a sistema, in pochi anni e senza grandi investimenti, tutte le strutture e infrastrutture
regionali già esistenti (ma che oggi sono mal o sotto-utilizzate) in un unico ‘porto-regione’. Perché, allora, l’«ultima chiamata»? Perché questa stessa idea ce l’hanno anche altre realtà – oggi in Slovenia e
domani, forse, in Croazia – e se il Friuli Venezia Giulia non si muove subito non ci sarà più spazio per un altro porto-regione nell’Alto Adriatico con tutto ciò che ne può conseguire in termini di inevitabile
ulteriore declino, non solo della nostra economia ma anche di quella dell’Italia adriatica

Addition of Unsaturated Fatty Acids down-Modulates Heat Shock Gene Expression and Produces Attenuated Strains in the Fungus Histoplasma capsulatum
No full textHistoplasma capsulatum is the causative agent of histoplasmosis, a systemic fungal disease world-wide in occurrence and the most common respiratory mycotic infection affecting humans and animals. This organism, that consists of a pathogenic yeast phase present in human tissue and a saprobic mycelial phase found in soil, represents at a molecular level, the most extensively studied of the dimorphic pathogenic fungi (Maresca and Kobayashi, 1989). In culture, the transition from one phase to the other can be triggered reversibly by shifting the temperature of incubation between 25° (mycelia) and 37°C (yeast). This implies that each growth phase is an adaptation to two remarkably different environments. Therefore, it is likely that the temperature-induced phase transition and the events in the establishment of infection are intimately interrelated and, unlike the case in higher eukaryotes, the differentiation process in dimorphic fungi represents an adaptation to a new environment. In fact, the organism must face challenges that may not be strictly related to dimorphism to proceed towards phase transition (e.g., higher temperature, different redox potential and nutrients, presence of new degradative enzymes, etc.)

Dimorphism in Histoplasma capsulatum: a model for the study of cell differentiation in pathogenic fungi
No full textSeveral fungi can assume either a filamentous or a unicellular morphology in response to changes in environmental conditions. This process, known as dimorphism, is a characteristic of several pathogenic fungi, e.g., Histoplasma capsulatum, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, and appears to be directly related to adaptation from a saprobic to a parasitic existence. H. capsulatum is the most extensively studied of the dimorphic fungi, with a parasitic phase consisting of yeast cells and a saprobic mycelial phase. In culture, the transition of H. capsulatum from one phase to the other can be triggered reversibly by shifting the temperature of incubation between 25 degrees C (mycelia) and 37 degrees C (yeast phase). Mycelia are found in soil and never in infected tissue, in contrast to the yeast phase, which is the only form present in patients. The temperature-induced phase transition and the events in establishment of the disease state are very likely to be intimately related. Furthermore, the temperature-induced phase transition implies that each growth phase is an adaptation to two critically different environments. A fundamental question concerning dimorphism is the nature of the signal(s) that responds to temperature shifts. So far, both the responding cell component(s) and the mechanism(s) remain unclear. This review describes the work done in the last several years at the biochemical and molecular levels on the mechanisms involved in the mycelium to yeast phase transition and speculates on possible models of regulation of morphogenesis in dimorphic pathogenic fungi
