NMR-based quantification of rosmarinic and carnosic acids, GC-MS profile and bioactivity relevant to neurodegenerative disorders of Rosmarinus offici…
2013
Abstract A comparative study of phytochemicals content and biological properties of eight Rosmarinus officinalis (rosemary) populations (RO1–RO8) collected in different areas of Tunisia was carried out. Two of the main rosemary constituents, rosmarinic and carnosic acids, were quantified by an NMR technique. Carnosic acid content was higher than that of rosmarinic acid. The non-polar constituents were examined by GC and GC–MS. Total phenols and flavonoids content were also determined in order to discuss the possible correlation between these phytochemicals and bioactivity. Antioxidant activity was investigated through different in vitro assays. Sample RO3 from a sub-humid area showed the hi…

Tissue Engineering Biopolymers
2011
Tissue engineering has always been a multidisciplinary research area focused on tissue regeneration and restoration of organs function, through implantation of cells or tissues growing outside the body. According to increase in knowledge of the interactions between living organisms and biomaterials, development and diversification of biocompatible devices has brought the world of medicine to what has been the greatest therapeutic revolution of our times. The main challenge of biomaterials is not only related to "tolerance-biocompatibility" by the body but also in its functionality. A biomaterial must be able to positively interact with tissues and exercise those functions for which it was d…

LA SCUOLA SPAIS: RICERCA SCIENTIFICA E DIDATTICA DELLE SCIENZE IN UN CONTESTO MULTIDISCIPLINARE
2013
SPAIS si pone come obiettivo l’individuazione e il conseguente approfondimento delle conoscenze di base che sono necessarie nel campo della chimica, della fisica e delle scienze biologiche e naturali per comprendere e comunicare i contenuti fondamentali della moderna ricerca scientifica e tecnologica. L’edizione 2013 sul tema “ScientificaMente – le Neuroscienze” viene qui presentata evidenziandone particolarmente le implicazioni nella didattica della Chimica

Evoluzione di sistemi deposizionali di piattaforma continentale durante il Pleistocene superiore - Olocene: analisi sedimentologica di due carote pre…
2016
E’ stato condotto uno studio sedimentologico di due carote prelevate nell’offshore della Sicilia settentrionale allo scopo di analizzare i cambiamenti di regime deposizionale verificatisi nel Pleistocene superiore - Olocene. Sulle due carote, provenienti dal Golfo di Termini Imerese (2,74 m di lunghezza, profondità -126 m) e dalla Baia di Carini (1,35 m di lunghezza, profondità -194 m), sono state anche eseguite analisi geochimiche e micropaleontologiche. Da un punto di vista granulometrico in entrambe le carote si può notare che la parte inferiore è principalmente costituita da una granulometria grossolana (ghiaia, ghiaia sabbiosa) che passa ad una granulometria di tipo argillo-siltosa nel…
