“The family of soluble fullerene derivatives comprises a widely studied group of electron transporting molecules for use in organic electronic and optoelectronic devices. For electronic

applications, electron transporting (n-channel) materials are required for implementation into organic complementary logic circuit architectures. To date, few soluble Selleckchem QNZ candidate materials have been studied that fulfill the stringent requirements of high carrier mobility and air stability. Here we present a study of three soluble fullerenes with varying electron affinity to assess the impact of electronic structure on device performance and air stability. Through theoretical and experimental analysis of the electronic structure, characterization of thin-film structure, and characterization PF477736 in vivo of transistor device properties we find that the air stability of the present series of fullerenes not only depends on the absolute electron affinity of the semiconductor but also on the disorder within the thin-film.

“Recurrence of hepatocellular carcinoma (HCC) is one of the major concerns following liver transplantation (LT). With the potential antitumor properties of interferon (IFN), their role in prevention of HCC recurrence is to be defined.

We retrospectively reviewed 46 patients who underwent LT for hepatitis C virus (HCV)-related HCC between January 2004 and December 2008. Twenty-four (52.2%) patients with biopsy-proven HCV recurrence received antiviral therapy (IFN group); their outcomes were compared with 22 patients (control group). There was no significant difference for tumor size, number, and type of neo-adjuvant therapy Givinostat order between the two groups. The 1- and 3-year overall patient survival (100% vs. 90.9% and 87.3% vs. 71.8%; P = 0.150) and tumor-free survival (100% vs. 72.7% and 83.1% vs. 67.5%; P = 0.214) between IFN and control group

were comparable. HCC recurrence was the most common cause of death (n = 6 of 12, 50%), all in the control group. During follow-up, seven (15.2%) patients developed HCC recurrence: one (4.1%) in the IFN group and six (27.3%) in the control group (P < 0.05). In conclusions, HCC recurrence rate and related deaths were significantly lower in patients that received post-transplant antiviral therapy for recurrent HCV.”
“The aim of this study was to determine results of kidney transplantation (KT) from controlled donation after cardio-circulatory death (DCD). Primary end-points were graft and patient survival, and post-transplant complications. The influence of delayed graft function (DGF) on graft survival and DGF risk factors were analyzed as secondary end-points. This is a retrospective mono-center review of a consecutive series of 59 DCD-KT performed between 2005 and 2010. Overall graft survival was 96.6%, 94.6%, and 90.7% at 3 months, 1 and 3 years, respectively. Main cause of graft loss was patients death with a functioning graft. No primary nonfunction grafts.
