Promising Strategies for Preserving Adult Endothelium Health and Reversing Its Dysfunction: From Liquid Biopsy to New Omics Technologies and Noninvas…

2022

The endothelium has multiple functions, ranging from maintaining vascular homeostasis and providing nutrition and oxygen to tissues to evocating inflammation under adverse conditions and determining endothelial barrier disruption, resulting in dysfunction. Endothelial dysfunction represents a common condition associated with the pathogenesis of all diseases of the cardiovascular system, as well as of diseases of all of the other systems of the human body, including sepsis, acute respiratory distress syndrome, and COVID-19 respiratory distress. Such evidence is leading to the identification of potential biomarkers and therapeutic targets for preserving, reverting, or restoring endothelium in…

Aspetti tipo-cronologici e archeometrici delle ceramiche africane nel territorio di Cignana (Naro, AG, Sicilia)

2020

Il progetto di ricerca, condotto in cotutela tra l'Università di Palermo e Aix-Marseille Université, si basa sullo studio delle ceramiche africane importate in Sicilia tra la fine del I e il VII secolo d.C.. La ricerca si basa sui frammenti - tutte le classi incluse - raccolti dal gruppo di ricerca di Palermo durante le ricognizioni archeologiche nei dintorni della villa romana di Cignana (Agrigento) e nell'entroterra di Termini Imerese (Palermo). L'approccio multidisciplinare archeologico ed archeometrico, condotto in collaborazione con diversi specialisti di queste discipline, ha permesso di definire l'origine delle diverse produzioni e di riflettere sulla loro circolazione in Sicilia, in…

Agricultural management affects the response of soil bacterial community structure and respiration to water-stress

2013

International audience; Soil microorganisms are responsible for organic matter decomposition processes that regulate soil carbon storage and mineralisation to CO2. Climate change is predicted to increase the frequency of drought events, with uncertain consequences for soil microbial communities. In this study we tested the hypothesis that agricultural management used to enhance soil carbon stocks would increase the stability of microbial community structure and activity in response to water-stress. Soil was sampled from a long-term field trial with three soil carbon management systems and was used in a laboratory study of the effect of a dry wet cycle on organic C mineralisation and microbi…

Essential oils and their applications in agriculture and agricultural products: a literature analysis through VOSviewer.

2022

In agriculture, more attention has been paid to limit the amount of chemical plant protection products. A potential alternative solution has been found in essential oils (EOs), which appear as promising candidates for their properties (safe, bioactive, biodegradable products) in managing plant diseases in agriculture. Therefore, a co-occurrence analysis was carried out on the available literature on Scopus database, through network maps created by VOSviewer software in order to identify the EOs used in agriculture, agricultural products and their target application. USA and India appeared as the most productive countries in terms of documents and citations followed by Iran and Italy. The co…

Aldo Visalberghi and the italian School System in the Post-War Period

2021

The contribution aims to propose a reflection on the italian pedagogist and academic Aldo Visalberghi (1919-2007) who, influenced by the pedagogical theories of John Dewey (1859-1952), has critically analyzed the italian school of the immediate post-war period, which he himself called extremely authoritarian and, for this reason, demanding to live a change that transformed and improved the quality of teaching and learning of young italians. Through a critical reading of some bibliographical sources such as Scuola aperta published in 1960 and Insegnare ed apprendere. Un approccio evolutivo of 1988, it will be highlighted how Visalberghi offered to educators and teachers of his time suggestio…

Anhydrous Amorphous Calcium Oxalate Nanoparticles from Ionic Liquids: Stable Crystallization Intermediates in the Formation of Whewellite

2015

The mechanisms by which amorphous intermediates transform into crystalline materials are not well understood. To test the viability and the limits of the classical crystallization, new model systems for crystallization are needed. With a view to elucidating the formation of an amorphous precursor and its subsequent crystallization, the crystallization of calcium oxalate, a biomineral widely occurring in plants, is investigated. Amorphous calcium oxalate (ACO) precipitated from an aqueous solution is described as a hydrated metastable phase, as often observed during low-temperature inorganic synthesis and biomineralization. In the presence of water, ACO rapidly transforms into hydrated whewe…

Properties of the Binary Neutron Star Merger GW170817

2019

On August 17, 2017, the Advanced LIGO and Advanced Virgo gravitational-wave detectors observed a low-mass compact binary inspiral. The initial sky localization of the source of the gravitational-wave signal, GW170817, allowed electromagnetic observatories to identify NGC 4993 as the host galaxy. In this work, we improve initial estimates of the binary's properties, including component masses, spins, and tidal parameters, using the known source location, improved modeling, and recalibrated Virgo data. We extend the range of gravitational-wave frequencies considered down to 23 Hz, compared to 30 Hz in the initial analysis. We also compare results inferred using several signal models, which ar…
