Journal ArticleDOI
Laser Ablation as a Versatile Tool To Mimic Polyethylene Terephthalate Nanoplastic Pollutants: Characterization and Toxicology Assessment
Davide Magrì,Paola Sánchez-Moreno,Gianvito Caputo,Francesca Gatto,Francesca Gatto,Marina Veronesi,Giuseppe Bardi,Tiziano Catelani,Daniela Guarnieri,Athanassia Athanassiou,Pier Paolo Pompa,Despina Fragouli +11 more
TL;DR: A reliable top-down approach based on laser ablation of polymers to form polyethylene terephthalate (PET) nanoplastics, which mimic real environmental nanopollutants, unlike synthetic samples obtained by colloidal chemistry.
Journal ArticleDOI
Platinum nanozymes recover cellular ROS homeostasis in an oxidative stress-mediated disease model
Mauro Moglianetti,Elisa De Luca,Deborah Pedone,Deborah Pedone,Roberto Marotta,Tiziano Catelani,Barbara Sartori,Heinz Amenitsch,Saverio Francesco Retta,Pier Paolo Pompa +9 more
TL;DR: The potential of biocompatible platinum nanoparticles (Pt NPs) as antioxidant nanozymes is shown, which combine abundant cellular internalization and efficient scavenging activity of cellular reactive oxygen species (ROS), thus simultaneously integrating the functions of nanocarriers and antioxidant drugs.
Journal ArticleDOI
Metformin promotes tau aggregation and exacerbates abnormal behavior in a mouse model of tauopathy
Erica Barini,Odetta Antico,Yingjun Zhao,Yingjun Zhao,Francesco Asta,Valter Tucci,Tiziano Catelani,Roberto Marotta,Huaxi Xu,Huaxi Xu,Laura Gasparini +10 more
TL;DR: These findings indicate that metformin pro-aggregation effects mitigate the potential benefits arising from its dephosphorylating action, possibly leading to an overall increase of the risk of tauopathy in elderly diabetic patients.
Journal ArticleDOI
Rescuing Over-activated Microglia Restores Cognitive Performance in Juvenile Animals of the Dp(16) Mouse Model of Down Syndrome.
Bruno Pinto,Giovanni Morelli,Mohit Rastogi,Annalisa Savardi,Amos Fumagalli,Andrea Petretto,Martina Bartolucci,Emilio Varea,Tiziano Catelani,Andrea Contestabile,Laura E. Perlini,Laura Cancedda +11 more
TL;DR: The results suggest an involvement of microglia in Dp(16)-mouse cognitive deficits and identify a new potential therapeutic approach for cognitive disabilities in DS individuals.
Journal ArticleDOI
Enhanced mechanical performances and bioactivity of cell laden-graphene oxide/alginate hydrogels open new scenario for articular tissue engineering applications
Alessandra Marrella,Alessandra Marrella,Alberto Lagazzo,Fabrizio Barberis,Tiziano Catelani,Rodolfo Quarto,Silvia Scaglione +6 more
TL;DR: 3D GO/Alg hydrogel is a promising material for articular tissue engineering, where biomechanical requirements are crucial, as demonstrated by the statistically significant improvement of the viability of fibroblasts encapsulated in GO/ alginate hydrogels and by the absence of cytotoxicity of suspended GO flakes.
