Nanoparticles of a polyaspartamide-based brush copolymer for modified release of sorafenib: In vitro and in vivo evaluation.
2017
Abstract In this paper, we describe the preparation of polymeric nanoparticles (NPs) loaded with sorafenib for the treatment of hepatocellular carcinoma (HCC). A synthetic brush copolymer, named PHEA-BIB-ButMA (PBB), was synthesized by Atom Trasnfer Radical Polymerization (ATRP) starting from the α-poly( N -2-hydroxyethyl)- d , l -aspartamide (PHEA) and poly butyl methacrylate (ButMA). Empty and sorafenib loaded PBB NPs were, then, produced by using a dialysis method and showed spherical morphology, colloidal size, negative ζ potential and the ability to allow a sustained sorafenib release in physiological environment. Sorafenib loaded PBB NPs were tested in vitro on HCC cells in order to e…
Trap-assisted spectroscopy with REXTRAP
2007
International audience; As one of the fashionable techniques for nuclear spectroscopy experiments, the beam manipulation in gas-filled Penning traps permits the accurate measurement of some of the ground state properties of exotic nuclides. It was recently applied using REXTRAP for the measurement of the half-life of 38Ca, one of the 0+ → 0+ β-decaying nuclide of interest for the determination of the Ft value for super-allowed transitions, and the test of the unitarity of the CKM matrix. The experimental setup and the original method of beam purification adopted for this measurement is presented.
Nanomechanics of individual aerographite tetrapods
2017
Carbon-based three-dimensional aerographite networks, built from interconnected hollow tubular tetrapods of multilayer graphene, are ultra-lightweight materials recently discovered and ideal for advanced multifunctional applications. In order to predict the bulk mechanical behaviour of networks it is very important to understand the mechanics of their individual building blocks. Here we characterize the mechanical response of single aerographite tetrapods via in situ scanning electron and atomic force microscopy measurements. To understand the acquired results, which show that the overall behaviour of the tetrapod is governed by the buckling of the central joint, a mechanical nonlinear mode…
From Image to Investigation 3D Reconstruction with Perspective Restitution
2022
The memory of hundreds gone buildings is preserved by few photographic images. Perspective restitution with digital representation tools can be used today to reconstruct these buildings directly in 3D space. Digital representation has overcome many limitations that affected perspective restitution in the pre-digital era. In this paper the inner space of the church of San Michele in Trapani, destroyed at the end of the 50’, is reconstructed with the aid of three period photographic images. Some architectural elements that escaped destruction and are today located in a new church near Trapani have been surveyed with laser scanning and SfM photogrammetric techniques. Surveyed elements provided…
3D Technology for the Artworks Handling
2022
In this study we present how to create a box for the transport of artworks put in place during the restauration of three polymateric sculpures made with trapanese technique called ‘Legno, Tela e Colla’. Thanks to 3D technology, we created a ‘digital twin’ of manufacts that allowed us to design and build supports and boxes for different uses. In this way, it was possible not to touch the artworks directly, so without risks for them, and to work even at a distance without the works, also in different places.
