NANOmetric BIO-Banked MSC-Derived Exosome (NANOBIOME) as a Novel Approach to Regenerative Medicine
Get PDFMesenchymal stem cells (MSCs) are well known for their great potential in clinical applications. In fact, MSCs can differentiate into several cell lineages and show paracrine behavior by releasing endogenous factors that stimulate tissue repair and modulate local immune response. Each MSC type is affected by specific biobanking issues-technical issues as well as regulatory and ethical concerns-thus making it quite tricky to safely and commonly use MSC banking for swift regenerative applications. Extracellular vesicles (EVs) include a group of 150⁻1000 nm vesicles that are released by budding from the plasma membrane into biological fluids and/or in the culture medium from varied and heterogenic cell types. EVs consist of various vesicle types that are defined with different nomenclature such as exosomes, shedding vesicles, nanoparticles, microvesicles and apoptotic bodies. Ectosomes, micro- and nanoparticles generally refer to the direct release of single vesicles from the plasma membrane. While many studies describe exosomes as deriving from multivesicular bodies, solid evidence about the origin of EVs is often lacking. Extracellular vesicles represent an important portion of the cell secretome. Their numerous properties can be used for diagnostic, prognostic, and therapeutic uses, so EVs are considered to be innovative and smart theranostic tools. The aim of this review is to investigate the usefulness of exosomes as carriers of the whole information panel characterizing the use of MSCs in regenerative medicine. Our purpose is to make a step forward in the development of the NANOmetric BIO-banked MSC-derived Exosome (NANOBIOME).</p

Didattica e ricerca. L’esperienza del Laboratorio aragonese e sforzesco
Get PDFIn the workshop on Diplomatic correspondences in the Italian Renaissance, directed in January-May 2018 by Francesco Storti and Francesco Senatore in the Istituto italiano per gli studi filosofici of Naples, 12 undergraduate and graduate students learned to read and trascribe italian diplomatic dispatches of the 15th cent., producing a specimen of scientific edition. In the opinion of the author, such activities and similar ones are very useful for future school teachers and scholars and they could be introduced in the university and pHD courses of history. Students of humanistic sciences should have concrete contacts with the historical research on primary sources. On the other hand, editing of historical sources could become a marginal activity because it is not enough appreciated in the current research evaluation processes.

Cigarette cues capture attention of smokers and never-smokers, but for different reasons
No full textBACKGROUND:
While the notion that smokers reliably show higher reactivity to cigarette-related versus neutral cues is both theoretically and empirically supported, it is unclear why never-smokers also show enhanced brain responses to cigarette-related cues.
METHODS:
Using a repetitive picture viewing paradigm, in which responses evoked by affective cues are more resistant to habituation, we assessed the effects of stimulus repetition on event-related potentials (ERPs) evoked by pleasant, unpleasant, cigarette-related, and neutral images in 34 smokers (SMO) and 34 never-smokers (NEV). We examined the early posterior negativity (EPN) and the late positive potential (LPP), two ERP components which are sensitive to a picture's motivational qualities.
RESULTS:
Before stimulus repetition, pleasant, unpleasant, and cigarette-related cues produced greater EPN and LPP amplitudes than neutral cues in all subjects. During stimulus repetition, both components were similarly modulated by emotional arousal, such that pleasant, unpleasant, and cigarette-related cues evoked greater EPN and LPP amplitude, relative to neutral. Smoking status did not modulate these effects. While there were no group differences in self-reported stimulus ratings of valence for pleasant, unpleasant, or neutral stimuli, NEV rated cigarette-related cues as unpleasant. We observed a moderate, negative correlation between LPP amplitude and self-reported valence ratings of cigarette-related cues among NEV.
CONCLUSIONS:
These data suggest that cigarette-related cues capture attentional resources of both SMO and NEV, but for different reasons. For SMO, cigarette-related cues have acquired motivational significance through repeated associations with nicotine delivery, whereas for NEV, cigarette-related cues are perceived as unpleasant

Fotografie di Sergio Oriani
Il curatore della mostra, Stefano Zuffi, ha voluto inquadrare criticamente l’opera di Raffaello
proveniente dal Museo di Budapest, ponendola tra la Vergine delle Rocce di Francesco Melzi,
proveniente dall’Istituto delle Suore Orsoline di Milano e la Madonna della Rosa di Giovanni
Antonio Boltraffio, proveniente dal Museo Poldi Pezzoli della stessa città. L’architetto Corrado
Anselmi ha progettato un affascinante allestimento, concependolo come un percorso che si
sviluppa attraverso tre soste utili all’ammirazione delle opere. L’autore Francesco Murano,
spiega con ricchezza di particolari i vincoli del progetto illuminotecnico e le scelte luministiche.Once again, for the Christmas season, the Municipally of Milan decided to display an important work in the frame of the Palazzo Marino’s Alessi Hall. For this year 2014, the choice has been to propose the Estheràzy Madonna by Raphael, from the Museum of Budapest.
The exhibition curator, Stefano Zuffi, wanted to critically frame to work of Raphael by placing it between the Vegine delle Rocce (Virgin of the Rocks) by Francesco Melzi, coming from the Milan’s Istituto delle Suore Orsoline, and the Madonna della Rosa by Giovanni Boltraffio, from the Milanese Museo Poldi Pezzoli.
The Architect Corrado Anselmi designed a fascinating display, convinced as a path that develops through three stops that are useful for the enjoyment of the works.

Phantasy, Multiverse and Protopia: Ran Slavin's Israeli Futurism
No full textThe essay discusses Israeli artist Ran Slavin's transmedia production, since the 1990s, as a key example of Israeli Futurism. The essay contextualizes Slavin's films, multimedia installations, photography, soundscapes, CGI imagery, and tech-based output as a way to process the conflictual dynamics at the basis of the foundation of Israel, the mythologies of Judaism and the ongoing metamorphosis of Jewish identity. The author of this essay, Francesco Spampinato, is also the editor of this major retrospective monograph on Slavin's work
