A New Hyaluronic Acid Derivative Obtained from Atom Transfer Radical Polymerization as a siRNA Vector for CD44 Receptor Tumor Targeting.

2015

Two derivatives of hyaluronic acid (HA) have been synthesized by atom transfer radical polymerization (ATRP), starting from an ethylenediamino HA derivative (HA-EDA) and by using diethylaminoethyl methacrylate (DEAEMA) as a monomer for polymerization. Both samples, indicated as HA-EDA-pDEAEMA a and b, are able to condense siRNA, as determined by gel retardation assay and resulting complexes show a size and a zeta potential value dependent on polymerization number, as determined by dynamic light scattering measurements. In vitro studies performed on HCT 116 cell line, that over express CD44 receptor, demonstrate a receptor mediated uptake of complexes, regardless of their surface charge. New…

University incubator as catalyst of resources for academic spin-offs. The case of ARCA Consortium

2013

Today we can observe an increasing proliferation of new academic spin-off initiatives aimed to transfer knowledge from the university to the market. Due to their strategic role in enhancing the development of technological innovation, academic spin-offs can attain high levels of social performance and consonance with their environment. At the same time, they must overcome many difficulties if they are to achieve a high level of financial performance and growth. They are often considered to be mere vehicles for the transmission of knowledge, implying that their entrepreneurial potential is not fully exploited. According to the Resource Based View (RBV) the competitive disadvantage of an acad…

SCAFFOLD SINTETICO DI PHEA-PLA-PCL BIOCOMPATIBILE E BIOFUNZIONALE. STUDI PRELIMINARI SU MODELLO ANIMALE. NUOVE PROSPETTIVE NELLA CHIRURGIA RIGENERATI…

2016

Introduzione: L’ingegneria tissutale ha sviluppato polimeri sintetici biocompatibili e biofunzionali, capaci di fornire una struttura tridimensionale che supporti la crescita di nuovo tessuto autologo, mediante la migrazione di cellule del ricevente. Obiettivo del nostro studio è stato valutare la resistenza di uno scaffold di PHEA-PLA-PCL ai succhi biliari di un modello animale, per determinarne l’applicabilità nella chirurgia rigenerativa delle vie biliari (VB). Metodologia: Abbiamo utilizzato 10 conigli New Zealand (n=10 )di 1,5 kg di peso. Si è proceduto all’impianto di un innesto di circa 1,5 cm2 di scaffold polimerico, costituito da polimeri di PHEA-PLA-PCL, all’interno di una colecis…
