Use of autochthonous yeasts and bacteria in order to control Brettanomyces bruxellensis in wine
2017
Biocontrol strategies for the limitation of undesired microbial developments in foods and beverages represent a keystone toward the goal of more sustainable food systems. Brettanomyces bruxellensis is a wine spoilage microorganism that produces several compounds that are detrimental for the organoleptic quality of the wine, including some classes of volatile phenols. To control the proliferation of this yeast, sulfur dioxide is commonly employed, but the efficiency of this compound depends on the B. bruxellensis strain; and it is subject to wine composition and may induce the entrance in a viable, but nonculturable state of yeasts. Moreover, it can also elicit allergic reactions in humans. …
Agonist-induced formation of FGFR1 homodimers and signaling differ among members of the FGF family
2011
Fibroblast growth factor receptor 1 (FGFR1) is known to be activated by homodimerization in the presence of both the FGF agonist ligand and heparan sulfate glycosaminoglycan. FGFR1 homodimers in turn trigger a variety of downstream signaling cascades via autophosphorylation of tyrosine residues in the cytoplasmic domain of FGFR1. By means of Bioluminescence Energy Resonance Transfer (BRET) as a sign of FGFR1 homodimerization, we evaluated in HEK293T cells the effects of all known FGF agonist ligands on homodimer formation. A significant correlation between BRET(2) signaling and ERK1/2 phosphorylation was observed, leading to a further characterization of the binding and signaling properties…

From the great depression to bretton woods: Jacob Viner and international monetary stabilization (1930-1945)
2009
This paper examines Jacob Viner's contribution to the debate and the policy decision-making concerning international monetary policy from the Great Depression to the Bretton Woods agreements. An outstanding member of the so-called 'early Chicago School of Political Economy', Viner was actively engaged in the debate over the causes and cures of the Depression, emphasizing the important role international economic problems played in producing its onset and in reinforcing its duration. During the 1930s Viner was an outspoken supporter of international monetary cooperation, set up to secure exchange rates stability, which he regarded as a paramount factor in restoring business confidence and fo…
Pressures, rewards and teacher retention: a comparative study of primary teaching in England and Finland
2004
The article presents some findings from the York‐Jyvaskyla Teacher Professionalism project. The project was a follow‐up study to earlier case‐study research in six schools in Finland and six schools in England on the impact of educational reforms on teachers' work. Data were collected by re‐interviewing a sample of teachers from the original schools six years later. The views of English and Finnish teachers concerning the ways in which changes in practice, pay and working conditions affected their perception of teaching as a profession are contrasted. The crucial factors discouraging teachers from remaining in teaching were work intensification, low pay, deteriorating pupil behaviour and a …

Ether-Lipids Are Involved in Retinal Vegf Expression and in Postnatal Hyaloid Vessel Regression
2009
Purpose:Ether-lipids are phospholipids that represent about 13% of retinal lipids and whose exact functions remain unknown. However, the preferential esterification of polyunsaturated fatty acids (PUFAs) at the sn-2 position of ether-lipids and their liberation by an ether-lipid-specific phospholipase A2 suggest their involvement in cell signaling processes. Based on the data showing the persistence of the hyaloid vasculature in ether-lipid-deficient mice (DAPAT-/- mice, Rodemer et al Hum Mol Genet 2003), we further investigated the molecular mechanisms by which ether-lipids may regulate hyaloid vessels regression during post-natal development. Methods:C57BL/6 mice were treated at birth eit…
DIO SALVI IL RESTAURO. L’apporto inglese alla cultura della conservazione dei monumenti
2020
Sebbene già riuscissimo a percepire quanto rilevante fosse l’apporto inglese per aver contribuito alla definizione del restauro modernamente inteso, sino ad oggi mancavano ancora sia una chiara visione d’insieme delle articolate vicende connesse all'affermazione dei princìpi conservativi, sia una più approfondita conoscenza delle fonti documentarie, necessarie al fine di tracciare i profili culturali dei protagonisti e scandagliarne i contributi teorici. La ricostruzione delle vicende è sviluppata entro margini temporali estesi all'incirca per tre secoli, dalla fine del Seicento al principio del Nove-cento, e strutturata attraverso la traduzione e lo studio di testi perlopiù mai circolati i…
Metafisica ed eidetica: su un particolare aspetto della funzione meta
2012
Contemporary research on the meta-function, closely associated with names like Breton, Ricœur, Greisch, is continuous with the traditional question on metaphysics, which metaphysics itself raised in its historical development starting from Aristotle, followed by the exegetical readings in late antiquity, in Arabic philosophy and in Scholasticism. The analysis of meta-function as a peculiar characteristic of metaphysics highlights the double movement of transcendence and immanence, of going beyond and coming back. It shows how metaphysics overcomes physis to rediscover it in a formal way on a deeper ontological level by posing the question about “being as being”, which is not a natural objec…
La inmigración y el origen del Trabajo Social. Una historia en común
2021
El objeto de este artículo es vincular la inmigración con el Trabajo Social en los Estados Unidos y Gran Bretaña. A partir de la revisión de fuentes secundarias, se trata de establecer la contribución de las figuras pioneras del Trabajo Social y mostrar las principales aportaciones de la disciplina a la investigación y la intervención en el campo de las migraciones. Entre estas aportaciones destaca una literatura, en general, poco conocida, así como una serie de experiencias institucionales que se han considerado como los orígenes históricos del Trabajo Social contemporáneo. The aim of this article is to link immigration with social work in the United States and Great Britain. The article r…
