Thermoreversible gelation of kappa-carrageenan: relation between conformational transition and aggregation.
2003
Abstract We have studied, by optical rotation dispersion, light scattering and rheology, the κ-Carrageenan system to elucidate the processes involved in gel formation (on decreasing the temperature) and gel melting (on increasing the temperature). Our results show that, on decreasing the temperature, a conformational transition from coils to double helices first occurs, followed by aggregation of the double helices into domains and gel formation at appropriate polymer concentration. Structural details of this sequence are better revealed by re-heating the system. Melting appears as a two-step process characterized by first a conformational change of helices involved in junction zones betwee…
Interaction ofEscherichia colihemolysin with biological membranes
2001
Escherichia coli hemolysin (HlyA) is a membrane-permeabilizing protein belonging to the family of RTX-toxins. Lytic activity depends on binding of Ca2(+) to the C-terminus of the molecule. The N-terminus of HlyA harbors hydrophobic sequences that are believed to constitute the membrane-inserting domain. In this study, 13 HlyA cysteine-replacement mutants were constructed and labeled with the polarity-sensitive fluorescent probe 6-bromoacetyl-2-dimethylaminonaphthalene (badan). The fluorescence emission of the label was examined in soluble and membrane-bound toxin. Binding effected a major blue shift in the emission of six residues within the N-terminal hydrophobic domain, indicating inserti…
Esse.Re (nel) mondo. Arti visive e rinascita dal 1966 a oggi
2022
Nel complesso quadro distopico della pandemia il saggio prende in esame il progetto espositivo e curatoriale .RE, mostra che non si limita a presentare le ricerche di una selezione di artisti tra i più influenti dei nostri tempi ma si focalizza sull’urgente necessità di problematizzare le dicotomie arte/vita, azione/contemplazione, arte/anti-arte, nella prospettiva di una riflessione critica intorno a una raccolta di opere innovative, tanto nel metodo quanto nel contenuto. Vengono esaminate le opere più significative delle ricerche condotte da Alberto Burri, Saint Clair Cemin, Tony Cragg, Zang Hong Mei, Anselm Kiefer, Jeff Koons, Sol LeWitt, Emil Lukas, Mimmo Paladino, Claudio Parmiggiani, …
9 Development of an experimental tool to evaluate normal tissue 3D doses in external-beam radiotherapy
2018
Introduction Recently, cancer treatment improvement enabled an increase in patients’ survival rate. In more than half of the cases, radiotherapy participates in the cure for cancer. The efficacy of this technique is well known but it inevitably delivers doses to normal tissues exposing them to radio-induced complications risks [1] . Moreover, the longer patients’ life expectancy increases the risk of developing long-term complications such as second cancers. Thus, evaluating the risks following cancer treatment involving radiotherapy constitutes a major challenge. In this context, an experimental tool has been developed to evaluate normal tissue doses delivered by the different radiotherapy…

The case of literacy motivation : Playful 3D immersive learning environments and problem-focused education for blended digital storytelling
2018
The University of Patras' Library Services designed and offered to primary and secondary schools the pilot educational program “From the Ancient to the Modern Tablets”, featuring immersive multimedia learning experiences about the book history. The pilot program consisted of three stages: a playful library tour, followed by an interactive game-based digital storytelling activity with game elements, and a collaborative creative reflective hands-on activity. Utilizing the avatar psychology power, the visualization and simulation affordances of 3D immersive learning environments and the appeal of storytelling and game-based learning, the “gamified” blended narrative on the book evolution enabl…
