Highly degradable porous melt-derived bioactive glass foam scaffolds for bone regeneration
Amy Nommeots-Nomm,Sheyda Labbaf,Aine Devlin,Naomi M. Todd,Hua Geng,Anu K. Solanki,Hok Man Tang,Polytimi Perdika,Alessandra Pinna,Fatemeh Ejeian,Olga Tsigkou,Peter D. Lee,Mohammad Hossein Nasr Esfahani,Christopher A. Mitchell,Julian R. Jones +14 more
TL;DR: A method for creating porous melt-derived bioactive glass foam scaffolds with low silica content with unexpectedly rapid bone regeneration in a rabbit model is introduced and in vivo data is reported.
Journal ArticleDOI

TL;DR: This review provides guidance to prepare and plan efficient sampling campaigns to collect sufficient PM mass for various purposes in a reasonable timeframe and highlights that predictive modelling can help to identify pollution hotspots in an urban environment for the efficient collection of PM mass.
Journal ArticleDOI
Ceria nanoparticles for the treatment of Parkinson-like diseases induced by chronic manganese intoxication
Alessandra Pinna,Luca Malfatti,Grazia Galleri,Roberto Manetti,Sara Cossu,Gaia Giovanna Maria Rocchitta,Rossana Migheli,Pier Andrea Serra,Plinio Innocenzi +8 more
TL;DR: Results show a protective role of nanoceria both on PC12 cells survival and dopamine metabolism, which makes this class of nanoparticles a potential candidate for the treatment of Parkinson-like diseases induced by chronic manganese intoxication.
Journal ArticleDOI
Nanoceria provides antioxidant and osteogenic properties to mesoporous silica nanoparticles for osteoporosis treatment.
Alessandra Pinna,Mohammad Torki Baghbaderani,Victoria Vigil Hernández,Parichart Naruphontjirakul,Siwei Li,Taneisha McFarlane,Daniel Hachim,Molly M. Stevens,Alexandra E. Porter,Julian R. Jones +9 more
TL;DR: In this article, the capability of the ROS-scavenger nanoceria encapsulated within mesoporous silica nanoparticles (Ce@MSNs) to treat osteoporosis using a pre-osteoblast MC3T3-E1 cell monoculture in stressed and normal conditions was tested.
Journal ArticleDOI
Effect of exposure to CeO 2 nanoparticles on ram spermatozoa during storage at 4 °C for 96 hours
Laura Falchi,Grazia Galleri,Gian Mario Dore,Maria Teresa Zedda,Salvatore Pau,Luisa Bogliolo,Federica Ariu,Alessandra Pinna,S. Nieddu,Plinio Innocenzi,Sergio Ledda +10 more
TL;DR: Beneficial effects of CeO2 NPs are reported on kinematic and morphologic parameters of ram semen, such as motility and membrane integrity following 96 h of exposure, and no genotoxic effects are proved.
