Identification of aphidicolin-induced fragile sites in domestic pig chromosomes
La Biblioteca Digital sobre Migraciones e Interculturalidad è un'iniziativa della fondazione FUDEPA (Fundación para el Desarrollo de los Pueblos de Andalucía) che ha come obiettivo la raccolta e la messa a disposizione di tutta la documentazione pubblicata in Spagna (monografie, articoli di riviste, letteratura grigia) relativa alle tematiche connesse al fenomeno delle migrazioni e della interculturalità (razzismo, xenofobia, educazione interculturale e relativa legislazione in materia).

Entrepreneurial Behavior as Learning Processes in a Transgenerational Entrepreneurial Family
Within the extant body of literature, little is known as to how transgenerational entrepreneurial families develop entrepreneurial mind-sets in order to create value across generations. Accordingly, this chapter aims to explore the role of the family ownership group in entrepreneurial behavior by examining the entrepreneurial learning process in a transgenerational entrepreneurial family. In achieving this aim, the 4I organizational learning framework by Crossan et al. (An organizational learning framework: From intuition to institution. Academy of Management Review 24 (3): 522-537, 1999) is adapted as a theoretical lens. The empirical evidence that draws upon evidence from a detailed longitudinal case study illustrates the interjectory influence of the family ownership group within this process, suggesting that entrepreneurial learning in a transgenerational family firm is embedded at the family group level and reproduced and co-created as a result of resilient entrepreneurial behavior
Cryptococcus neoformans Intracellular Proliferation and Capsule Size Determines Early Macrophage Control of Infection.
Cryptococcus neoformans is a significant fungal pathogen of immunocompromised patients. Many questions remain regarding the function of macrophages in normal clearance of cryptococcal infection and the defects present in uncontrolled cryptococcosis. Two current limitations are: 1) The difficulties in interpreting studies using isolated macrophages in the context of the progression of infection, and 2) The use of high resolution imaging in understanding immune cell behavior during animal infection. Here we describe a high-content imaging method in a zebrafish model of cryptococcosis that permits the detailed analysis of macrophage interactions with C. neoformans during infection. Using this approach we demonstrate that, while macrophages are critical for control of C. neoformans, a failure of macrophage response is not the limiting defect in fatal infections. We find phagocytosis is restrained very early in infection and that increases in cryptococcal number are driven by intracellular proliferation. We show that macrophages preferentially phagocytose cryptococci with smaller polysaccharide capsules and that capsule size is greatly increased over twenty-four hours of infection, a change that is sufficient to severely limit further phagocytosis. Thus, high-content imaging of cryptococcal infection in vivo demonstrates how very early interactions between macrophages and cryptococci are critical in the outcome of cryptococcosis
