The development of a scaffold able to mimic the mechanical properties of elastic tissues and to induce local angiogenesis by controlled release of angiogenic growth factors could be applied in the treatment of several ischemic diseases. For this purpose a composite scaffold made of a poly(ether)urethane-polydimethylsiloxane (PEtU-PDMS) semi-interpenetrating polymeric network (semi-IPN) and fibrin loaded growth factors (GFs), such as VEGF and bFGF, was manufactured using spray, phase-inversion technique. To evaluate the contribution of each scaffold component with respect to tissue response and in particular to blood vessel formation, three different scaffold formulations were developed as follows: 1) bare PEtU-PDMS; 2) PEtU-PDMS/Fibrin; and 3) PEtU-PDMS/Fibrin + GFs.

Serum gamma-glutamyltransferase (GGT) is thought to derive from the liver, but its values predict morbidity and mortality for several diseases, such as cardiac infarction, stroke, diabetes, renal failure and cancer. We assessed total GGT and its fractions in the culture supernatants of human cell lines (melanoma, prostate cancer, bronchial epithelium) by gel filtration chromatography. We also compared the GGT elution profile in plasma and the corresponding very-low-density lipoprotein (VLDL) fraction.
