Effects of Organoclay on Morphology and Properties of Nanocomposites Based on LDPE/PA6 Blends without and with SEBS-g-MA
2009
LDPE/PA-6 blends (75/25 wt/wt) were added with SEBS-g-MA (S) and/or an organoclay (20A) using different compounding sequences and the morphology and the properties of the blends or composites were investigated. An XRD study of the nanocomposites with pure polymers showed that 20A is intercalated by LDPE or PA-6 chains, whereas it is exfoliated by S if the clay concentration does not exceed 10 wt%. The SEM investigation showed that both S and 20A behave as efficient emulsifying agents for the LDPE/PA-6 blends. However, their effect on the mechanical properties was found to be opposite: S enhanced toughness but lowered the stiffness, whereas 20A improved the elastic modulus but impaired the i…

MONITORAGGIO ECO-COLORDOPPLER DEL RENE TRAPIANTATO.NOSTRA ESPERIENZA
2005
Introduzione: La metodica ultrasonografica, come è noto, scevra da complicanze, ripetibile, non invasiva ed altamente tollerata dal paziente, consente un attento monitoraggio sia delle caratteristiche anatomomorfologiche del graft (ATN,rigetto,intossicazione da farmaci,infarto),sia l’immediata diagnosi di complicanze post-operatorie (raccolte fluide perirenali, idronefrosi,trombosi vascolari).L’integrazione con power-colordoppler consente altresì il corretto monitoraggio delle condizioni di perfusione d’organo, desunte dai dati connessi alla valutazione seriata delle resistenze parenchimali. Materiali e metodi: La casistica è limitata agli ultimi tre anni di attività su un gruppo di 22 pazi…

Note sulle arti decorative a Malta. Inediti argenti siciliani di inizio XIX secolo.
2015
L’articolo si occupa di preziosi e inediti argenti siciliani di inizio Ottocento (ante 1826/1829), tra Rococò e Neoclassicismo, che si trovano a Malta. La maggior parte di essi recano il marchio consolare della città di Catania e sono stati realizzati negli anni 1810-1812. The article deals with precious and unpublished Sicilian silverware of the early nineteenth century (ante 1826/1829), between Rococo and Neoclassicism, that are located in Malta. Most of them bear the consular city mark of Catania and were made in the years 1810-1812.
New complex polycyclic compounds: Synthesis, antiproliferative activity and mechanism of action
2020
Abstract Polycyclic or O-glycoconiugate polycyclic compounds 1a-g were previously tested for their in vitro antiproliferative activity. In this series of compounds, activity increases as log P decreases. Specifically, compounds 1d and 1g showed lower log P values together with the best antiproliferative profiles. With the aim of extending our understanding of the structure–activity relationship (SAR) of this class of compounds, we prepared new polycyclic derivatives 2a-c, which bear on each of the two phenyl rings hydrophilic substituents (OH, SO2NH2 or NHCOCH3). These substituents are able to form hydrogen bonds and to decrease the partition coefficient value as compared with compound 1d. …
Expression of a glucocorticoid receptor (D1GR1) in several tissues of the teleost fish Dicentrarchus labrax
2008
Since glucocorticoids have a role in maintaining the homeostatic status in fish, in the present paper mRNA expression (in situ hybridization) and tissue immunohistochemical localization of a glucocorticoid receptor (DlGR1) in several Dicentrarchus labrax organs are reported. Riboprobe and specific antibodies were prepared by using the DlGR1 that has been previously cloned and sequenced from peritoneal cavity leukocytes. Both mRNA and receptor were identified in head kidney, spleen, gills, intestine, heart and liver tissues. The functional roles of DlGR1 localization are discussed.
Synthesis and biological evaluation of a novel MUC1 glycopeptide conjugate vaccine candidate comprising a 4’-deoxy-4’-fluoro-Thomsen–Friedenreich epi…
2015
The development of selective anticancer vaccines that provide enhanced protection against tumor recurrence and metastasis has been the subject of intense research in the scientific community. The tumor-associated glycoprotein MUC1 represents a well-established target for cancer immunotherapy and has been used for the construction of various synthetic vaccine candidates. However, many of these vaccine prototypes suffer from an inherent low immunogenicity and are susceptible to rapid in vivo degradation. To overcome these drawbacks, novel fluorinated MUC1 glycopeptide-BSA/TTox conjugate vaccines have been prepared. Immunization of mice with the 4’F-TF-MUC1-TTox conjugate resulted in strong im…
A taxonomic nightmare comes true: phylogeny and biogeography of glassworts (Salicornia L., Chenopodiaceae)
2007
In this study we analysed ETS sequence data of 164 accessions belonging to 31 taxa of Salicornia, a widespread, hygrohalophytic genus of succulent, annual herbs of Chenopodiaceae subfam. Salicornioideae, to investigate phylogenetic and biogeographical patterns and hypothesise about the processes that shaped them. Furthermore, our aim was to understand the reasons for the notorious taxonomic difficulties in Salicornia. Salicornia probably originated during the Miocene somewhere between the Mediterranean and Central Asia from within the perennial Sarcocornia and started to diversify during Late Pliocene/Early Pleistocene. The climatic deterioration and landscape-evolution caused by orogenetic…
