Marisa Mori e la libertà della pittura
No full textIntroduzione alla mostra, ideata e curata da E. Acanfora e C. Toti, dedicata alla pittrice Marisa Mori, che fu allieva di Felice Casorati e si orientò quindi al Futurismo. La mostra riscopre le opere della pittrice negli anni in cui fu legata al Lyceum Internazionale di Firenze. La scelta delle opere esposte si deve a E. Acanfora e C. Toti
Interventions, Productions and Collaborations:the relationship between RAI and visual artists
No full textOn the 17th May 1952, before RAI Radiotelevisione Italiana Studios began their regular broadcast from Milan, the Spatialist painter and sculptor Lucio Fontana broadcast his own experimental ‘artwork’ on Italian television, beginning a fruitful relationship between RAI and visual artists. For some, it provided careers as designers and art directors, such as the painter Mario Sasso and the Arte Povera artist Pino Pascali, while for others, who were given unique access to RAI’s television apparatus, it was an opportunity to explore their own artistic experimentations with an expensive and exclusive medium, such as Carlo Quartucci and Gianni Toti. RAI also hosted seminal artists’ performances on screen including John Cage and Fabio Mauri. This article, based on documents and interviews collected during the Arts and Humanities Research Council funded project REWINDItalia, discusses these and other seminal cases as well as tracing and assessing the history of this fruitful and complex exchange between RAI and visual artists
Chorioamnionitis and fetal/neonatal brain injury
No full textChorioamnionitis (CA) is the leading cause of preterm birth and neonatal complications. Even in the absence of a proven infection, fetuses and neonates present a systemic inflammatory response which can be identified by radiological and morphological examination of the thymus. The frequent occurrence of brain injury in neonates with CA is probably linked to systemic, unspecific mechanisms which have not yet been completely clarified. Only by relating placental pathology to clinical evaluation of the newborn will it be possible to achieve a better understanding of these infections and to reduce long-term morbidity and mortality.

Corrigendum: Metabolic Food Waste and Ecological Impact of Obesity in FAO World's Region (Frontiers in Nutrition, (2019), 6, 10.3389/fnut.2019.00126)
No full textIn the original article, there was a mistake in the legend for Figure 2 as published. It was not written as millions of kg in MFW(kgCO2eq). The correct legend appears below. Figure 2. Metabolic Food Waste corresponding to Excess Body Fat from FBS commodities in overweight and obese population expressed as (A) GHG emission, MFW(millions kgCO2eq); (B) water consumed, MFW(millions m3); and (C) land used, MFW(millions m2). EU, Europe; NAO, North America and Oceania; LA, Latin America; IA, Industrialized Asia; NAWCA, North Africa, West and Central Asia; SSEA, South and Southeast Asia; SSA, Sub-Saharan Africa. In the original article, there was an error in Table 1 as published. It was written MFW(tons of food) instead of MFW(kg of food). The correct title appears below. Table 1. Metabolic Food Waste [MFW(kg of food)] corresponding to Excess Body Fat by BMI categories (OW, Overweight; OB, Obesity). In the original article, there was an error. The values of MFW(tons of food) were expressed in gigatons instead of millions of tons. Corrections have been made to the Abstract: The overall impact of MFW(tons of food) in the world corresponds to 140.7 million tons associated to overweight and obesity. Between the different regions, EUis responsible of the greatest amount of MFW(tons of food) volume (39.2 million tons), followed by NAO (32.5 million tons)
Modifications of the freeze-cleaved circulating platelet membrane in hypercholesterolemic rabbits, prevented by AD6
No full textCirculating platelets present on their membrane some protuberances, placed among the plasma-membrane particles, when examined with F.E. technique. Statistic tests have shown a significant increase in the average number of such protuoerances in the platelets of hypercholesterolemic (15 - and 45 days) rabbits.
After i.v. administration of AD (8-mono-chloro carbochromen, a substance with a supposed anti-aggregaging action) the number of the protuberances of circulating platelets in the hypercholesterolemic rabbits approaches to the average values of the normocholesterolemic ones
Ribozymes: Analytical Solution of the One-Substrate, Two-Intermediate Reversible Scheme for Enzyme Reactions
No full textAbstract The paper presents a kinetic analysis of a reversible enzymatic reaction S! P
involving two intermediate compounds under the condition [E]0≫[S]0+[P]0. For the case of
mono-exponential behavior, we derive an equation for kobs as a function of [E]0, which
emphasizes the pitfalls of oversimplifying kinetic schemes (such as the Michaelis-Menten
model) for ribozyme studies. This novel apparent rate constant, which has been arrived at
through mechanistic considerations, is analyzed, and the characteristic parameters obtained.
The equation, which seems to fit experimental data better than conventional approximations,
is used to analyze a single turnover study on an ADC1 ribozyme drawn from hepatitis
delta virus RNA. The microscopic kinetic constants for such enzyme are evaluated and its
mono-exponential behavior verified.
Key words: ribozyme kinetics . Michaelis-Menten . low catalytic enzyme . kinetic analysis .

Knowledge discovery from textual sources by using semantic similarity
No full textWe propose a methodology to automatically discover characterizing knowledge from textual sources, with the purpose of semantically categorizing them and clustering them together according to their subjects. Such a methodology is based upon several challenging steps, like terminology extraction and disambiguation, semantic similarity identification via ontology alignment, and a core pattern-based strategy for automatic ontology building. This methodology was originally devised as an extension of PRAISED, our abbreviation identification and resolution proposal, with the purpose of allowing us to resolve previously unresolvable abbreviations, whose explanation either escapes the system's proximity-based approach or is not found within the very source text they are featured in. By moving from a paper-by-paper, mainly syntactical process to a corpus-based, semantic approach, it will be in fact possible to dramatically enhance our system in terms of its resolution capabilities. Nevertheless, the strategy we present here is not tied to this specific task, but is instead of relevance for a variety of contexts, and might therefore find a far wider applicability for other advanced knowledge extraction and discovery systems.
