Radiation-tailored xyloglucan-doxorubicin nanoparticles for cancer therapy
2022
Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. They are widely utilized in biomedical applications, for tissue engineering and wound management, and as excipients of pharmaceutical formulations. In cancer therapy, the development of nanoscale drug delivery systems aims at addressing issues related to the low efficacy of chemotherapeutics and protein drugs due to poor solubility and stability, and to off-target effects that severely affect patients’ body conditions. Biocompatibility, availability of functional groups, amenability of chemical derivatisation and multifunctional conjugation with drugs and targeting ligands make polysaccharide nanoparticles intere…
Effect of natural sea salt on physicochemical and textural properties of low sodium durum wheat bread
2015
Today, the dietary salt intake is considerably higher than the recommendations of the EFSA for good health (3-4 g salt/day). Several initiatives have been undertaken for a reduction in salt intake. The traditional use of sodium chioride (NaCI) fulfils various important rheological, technological and sensory properties in manufacturing of baked goods. However, using NaCI in the production of food has been controversially discussed since a high intake of sodium is associated with hypertension (1). Recently, the Reg (EU) 1924/2006 on nutrition and health claims made on foods makes it possible to claims on a label 'low sodium/salt', 'very low sodium/salt' and 'sodium free or salt free' for food…
Large-scale manufacturing of radiation sculptured therapeutic nanogels
2013
Nanogels (NGs), or small particles formed by physically or chemically crosslinked polymer networks, represent a niche in the development of “smart” nanoparticles for drug delivery and diagnostics. Yet, they offerunique advantages over other systems, including a large and flexible surface for multivalent bio-conjugation; an internal 3D aqueous environment for incorporation and protection of (bio)molecular drugs; the possibility to entrap light-activemolecules, metal or mineral nanoparticles for imaging or phototherapeutic purposes; stimuli-responsiveness to achieve temporal and/or site control of the release function and biocompatibility. The availability of inexpensive, robust and versatile…

An experimental campaign to investigate sustainability issues in Single Point Incremental Forming processes
2012
Sustainability issues are crucial topics in manufacturing and the environmental burdens reduction for processes is highly requested. In particular, the environmental sustainability evaluation for sheet metal forming processes is an widely investigated topic since there is still a lack of knowledge on modeling issues. The main tasks are related to a more efficient materials use and to energy savings. Moreover, forming technologies environmental impacts are essentially process-dependent. A deep analysis of the cause-effect linkages (between process and material parameters and energy consumption, for instance), within each process, would be necessary to properly model environmental impacts and…
Influence of Surface-Related Phenomena on Mechanism, Selectivity, and Conversion of TiO2 -Induced Photocatalytic Reactions
2018
Heterogeneous photocatalysis is the result of an inextricable connection of several factors differently contributing to the overall process. Photon absorption is the “sine qua non” condition for the reaction to occur. In fact, photons can be considered as immaterial reactants, and all of the phenomena related to the interaction of light–matter play a prominent role. However, other factors contribute in a concerted way to address the reaction, so that the relative contribution of each of them is often difficult to evaluate. In this framework, the present paper highlights some aspects of the interaction of TiO 2 surface-adsorbate species that could be underestimated and their influence on the…
