BACKGROUND Oxidative damage of DNA and RNA has been associated with mortality of patients with different ***,there is no published data on the potential use of DNA and RNA oxidative damage to predict the prognosis of patients with hepatocellular carcinoma(HCC)undergoing liver transplantation(LT).AIM To determine whether patients with increased DNA and RNA oxidative damage prior to LT for HCC have a poor LT *** Patients with HCC who underwent LT were included in this observational and retrospective *** levels of all three oxidized guanine species(OGS)were measured prior to LT since guanine is the nucleobase that forms DNA and RNA most prone to *** mortality at 1 year was the end-point *** Surviving patients(n=101)showed lower serum OGS levels(P=0.01)and lower age of the liver donor(P=0.03)than non-surviving patients(n=13).An association between serum OGS levels prior to LT and 1-year LT(odds ratio=2.079;95%confidence interval=1.356-3.189;P=0.001)was found in the logistic regression *** The main new finding was that high serum OGS concentration prior to LT was associated with the mortality 1 year after LT in HCC patients.

As for unmanned aircraft, the knowledge of the aircraft performance is directly related with the navigation, guidance, and control system programming. Therefore, the measured data in each phase of the flight must be sufficiently precise to obtain a good characterization of *** article proposes new methods of sending information to ground, which make it possible to know the aircraft behavior accurately, and for this purpose, four contributions have been made for ALO(Avión Ligero de Observación, Spanish acronym for Light Observation Aircraft). Currently, the characterization is based on data obtained at ten samples per second, insufficient to acquire detailed knowledge of what happened during the whole flight of an aircraft. As a result of these contributions, many more samples per second of accelerations and angular velocities are obtained at the most critical moments of the flight, such as takeoff or landing. Among the improvements included are data compression techniques, providing references to locate the measured data in time and identifying labels of each parameter.
