La pedagogia clinica a supporto dell’accompagnamento genitoriale: uno studio di caso
No full textIl presente contributo intende indagare, attraverso uno studio di caso, le modalità attraverso cui i membri di una famiglia possono attraversare e superare la crisi della propria progettualità in seguito alla scoperta e all’arrivo di un figlio con disabilità. Vengono pertanto approfondite alcune modalità di accompagnamento
pedagogico a cui la famiglia può affidarsi per intraprendere lo straordinario
percorso di scoperta e accettazione della disabilità (Muzi & Ballerini, 2023), quale
ad esempio la consulenza pedagogica (Negri, 2014), la tecnica del Parent Training
(Vio, Menazza & Bacci, 2010) e l’associazionismo familiare (Taddei, 2021)
It’s all about the surface! Vibrational spectroscopy applied to the study of biomimetic surfaces in Tissue Engineering
No full textTissue Engineering is a multidisciplinary field aimed at the creation of biological substitutes that restore and maintain the biological function of a damaged tissue. The key of the success of these biomedical devices lies into surface interactions with living tissues, therefore a common strategy is to create biomimetic surfaces that helps cells to colonize the biomaterial, leading to tissue healing.
Vibrational spectroscopy, in particular Raman, apart from being mainly surface and non-destructive technique, is extremely sensitive to changes in structure and molecular interactions, thus its use in investigating biomimetic devices is increasing.
In particular, we have recently used vibrational spectroscopies to investigate different biomimetic materials and to test some of their proprieties:
- self-assembling peptides adsorbed on titanium surfaces for bone implants [1], analyzed before and after attack from free radicals (obtained by gamma-radiolysis and mimicking inflammation processes) [2], with the aim to evaluate their capability in resisting to oxidative stress;
- composite (ceramic-polymer, polymer-polymer) bioresorbable biomaterials [3, 4];
- hydroxyapatite nanomaterials functionalized with proteins to increase biocompatibility [5-7].

Semi-empirical calculations of the magnetic properties of condensed hydrocarbons
No full textThe uncoupled Hartree-Fock perturbation method has been used to evaluate the contribution of ring currents to proton shielding constants, magnetic susceptibilities and anisotropies of large condensed hydrocarbons. Good agreement was found between experimental and calculated values. A comparison with HMO and ASMO methods is reported and the ring-current model is discussed
