Thermo-responsive properties of methylcellulose hydrogels for cell sheet engineering
No full textMethylcellulose (MC) hydrogels change their affinity to water depending on their temperature and can thus be used as substrates for cell sheet engineering. In this work, we characterize the thermo-responsive properties of 8% w/v MC hydrogels, produced in two saline solutions (i.e., Na2SO4 and phosphate buffered saline) at different concentrations, by investigating the rheological properties and the UV-absorbance in function of temperature. Both rheological and UV-spectroscopy tests showed that the addition of salts to MC hydrogels allowed lowering the LCST of the MC hydrogel; moreover, hydrogels produced in 0.1 M Na2SO4 or PBS 20 g/L were proved to be particularly promising for cell sheet engineering application, showing a LCST below 37 degrees C

Cross-Linking Strategies for Electrospun Gelatin Scaffolds
No full textElectrospinning is an exceptional technology to fabricate sub-micrometric fiber scaffolds for regenerative medicine applications and to mimic the morphology and the chemistry of the natural extracellular matrix (ECM). Although most synthetic and natural polymers can be electrospun, gelatin frequently represents a material of choice due to the presence of cell-interactive motifs, its wide availability, low cost, easy processability, and biodegradability. However, cross-linking is required to stabilize the structure of the electrospun matrices and avoid gelatin dissolution at body temperature. Different physical and chemical cross-linking protocols have been described to improve electrospun gelatin stability and to preserve the morphological fibrous arrangement of the electrospun gelatin scaffolds. Here, we review the main current strategies. For each method, the cross-linking mechanism and its efficiency, the influence of electrospinning parameters, and the resulting fiber morphology are considered. The main drawbacks as well as the open challenges are also discussed

Tuneable physico-mechanical properties of chemically crosslinked gelatin hydrogels for adipose tissue engineering
No full textIl colombo di città: stima della numerosità di popolazione nel Centro Storico di Padova.
No full textLa popolazione di colombo urbano (Columba livia var. domestica) insediata nel contesto patavino è sicuramente percepita come ingente, come testimoniano le segnalazioni effettuate dagli stessi cittadini, ma la determinazione del numero reale di esemplari presenti, necessaria per poter intraprendere qualsivoglia misura di controllo, risulta sovente problematica. Per questo motivo, l'attività periodica di monitoraggio numerico
della popolazione colombacea rappresenta uno strumento prezioso ed irrinunciabile per un corretto management dell’avifauna. Il presente documento costituisce il rapporto tecnico dell'attività di stima della popolazione urbana di C. livia condotta nell'anno 2013
