Safety assessment of food-contact paper and board using a battery of short-term toxicity tests: European union BIOSAFEPAPER project.

2005

International audience; An European Union (EU)-funded project QLK1-CT-2001-00930 (BIOSAFEPAPER) involves the development, validation and intercalibration of a short-term battery of toxicological tests for the safety assessment of food-contact paper and board. Dissemination of the results to industry, legislators (e.g. DG Consumer Protection, DG Enterprises, DG Research), standardization bodies such as CEN, and consumers will create an agreed risk evaluation procedure. The project involves pre-normative research in order to establish a set of in-vitro cytotoxicity and genotoxicity tests that will be easily adaptable to food-contact fibre-based materials and have endpoints relevant to consume…

Sarcophytolide: a new neuroprotective compound from the soft coral Sarcophyton glaucum

1998

Abstract Bioactivity-guided fractionation of an alcohol extract of the soft coral Sarcophyton glaucum collected from the intertidal areas and the fringing coral reefs near Hurghada, Red Sea, Egypt resulted in the isolation of a new lactone cembrane diterpene, sarcophytolide. The structure of this compound was deduced from its spectroscopic data and by comparison of the spectral data with those of known closely related cembrane-type compounds. In antimicrobial assays, the isolated compound exhibited a good activity towards Staphylococcus aureus, Pseudomonas aeruginosa , and Saccharomyces cerevisiae. Sarcophytolide was found to display a strong cytoprotective effect against glutamate-induced …

Note brevi a margine della proposta di riforma dei reati ambientali del gruppo di studio dell'associazione dei professori di diritto penale

2022

A partire dall’analisi della proposta di riforma dei reati contro l’ambiente elaborata dal Gruppo di studio dell’Associazione italiana dei Professori di Diritto Penale, il contributo riflette sui principali problemi teorici del diritto penale ambientale (tipizzazione dell’evento lesivo nelle fattispecie di inquinamento e di disastro ambientale, imputazione soggettiva dei delitti aggravati dall’evento, contrasto penale alle c.d. “ecomafie” nel settore dei rifiuti ecc.), mettendo a confronto le soluzioni suggerite nel testo con le prospettive di riforma contenute nella recente Proposta di Direttiva del Parlamento europeo e del Consiglio sulla Protezione dell’ambiente at- traverso il diritto p…

Indistinguishability-enhanced entanglement recovery by spatially localized operations and classical communication

2021

We extend a procedure exploiting spatial indistinguishability of identical particles to recover the spoiled entanglement between two qubits interacting with Markovian noisy environments. Here, the spatially localized operations and classical communication (sLOCC) operational framework is used to activate the entanglement restoration from the indistinguishable constituents. We consider the realistic scenario where noise acts for the whole duration of the process. Three standard types of noises are considered: a phase damping, a depolarizing, and an amplitude damping channel. Within this general scenario, we find the entanglement to be restored in an amount proportional to the degree of spati…

Walory ekoturystyczne Przesieki Śląskiej w okolicach dawnego (zapomnianego) miasta Schwirz (woj. opolskie, Polska)

2019

The present work outlines the natural, historical and cultural values of the selected fragment of Silesian Przesieka located in the southern part of a locality called Miejsce (the former town of Schwirz) (Świerczów municipality, Namysłów сounty, Opole Province, Poland). Here, the natural values are also mixed with unique historical, cultural and landscape values. The authors reconstruct the original riverbed of the Stobrawa River using a Digital Elevation Model. They describe border castles and their location by addressing the repeated records stating that these constitute earlier rudiments of a castle belonging to the same duchy. They describe the history of the locality Miejsce in its cur…

Palermo: Living Labs for Urban Regeneration

2016

The case of Palermo is described in this chapter as an example of Human Smart City (HSC) approach transferred to an extremely weak urban context in Southern Italy. The case focuses on the processes boosted through the Territorial Living Lab established in the city to tackle the topic of citizen participation in the solution of the main city challenges. It was based on a model of incremental and adaptive process of interaction, within a co-creative ecosystem, with the aim of improving housing quality. The model was shared by the players involved in the social innovation process. It would not have been possible without the Living Lab approach and the innovative momentum of design thinking tra…

Assessment of metallic materials required for shock stress protection

2017

Establishing which metallic materials are suitable to be used for the protection of operators and machinery, when subjected to stress impact in the drilling industry, for surface exploitation, mines and quarries, is a complex process. Due to the harsh operating conditions, a careful evaluation of the various materials used is of utmost importance. This paper addresses the issues relating to the methodology of determining the appropriate homogenous materials to be used, based on a correspondence between their characteristics and applications. Starting with a list of specific operating conditions, one has established a set of requirements and has assessed the market; the recommended materials…

Antineoplastic Drug-Induced Cardiotoxicity: A Redox Perspective

2018

Antineoplastic drugs can be associated with several side effects, including cardiovascular toxicity (CTX). Biochemical studies have identified multiple mechanisms of CTX. Chemoterapeutic agents can alter redox homeostasis by increasing the production of reactive oxygen species (ROS) and reactive nitrogen species RNS. Cellular sources of ROS/RNS are cardiomyocytes, endothelial cells, stromal and inflammatory cells in the heart. Mitochondria, peroxisomes and other subcellular components are central hubs that control redox homeostasis. Mitochondria are central targets for antineoplastic drug-induced CTX. Understanding the mechanisms of CTX is fundamental for effective cardioprotection, without…

In Itinere STRATEGIC ENVIRONMENTAL ASSESSMENT of an integrated provincial waste system

2009

In the paper, the practical problem of analysing in an integrated way the performance of provincial waste systems is approached, in the framework of the Strategic Environmental Assessment (SEA). In particular, the in itinere phase of SEA is analysed herein. After separating out a proper group of ambits, to which the waste system is supposed to determine relevant impacts, pertinent sets of single indicators are proposed. Through the adoption of such indicators the time trend of the system is investigated, and the suitability of each indicator is critically revised. The structure of the evaluation scheme, which is essentially based on the use of ambit issues and analytical indicators, calls …
