Hepatocellular carcinoma (HCC) represents the 5th commonest malignancy worldwide. Liver transplantation consist a radical and most efficient treatment for HCC. Tumor recurrence or metastases after liver transplantation is not uncommon. Hereby is presented a case of a patient transplanted for alcoholic liver disease and HCC and presented with bone metastases a few months later. Treatment with sorafenib and everolimus showed full regression of the metastases. In conclusion, the point of this report is to advertise a single case of total regression of bone lesions due to HCC recurrence, with the combination of mammalian target of rapamycin and sorafenib, along with radiation.

In this paper the provision of flexible generation is investigated by extracting steam from Rankine-cycle power stations during off-peak demand in order to charge thermal tanks that contain suitable phase-change materials(PCMs);at a later time when this is required and/or is economically effective,these thermal energy storage(TES)tanks can act as the heat sources of secondary thermal power plants in order to generate power,for example as evaporators of,e.g.,organic Rankine cycle(ORC)plants that are suitable for power generation at reduced temperatures and smaller *** type of solution offers greater flexibility than TES-only technologies that store thermal energy and release it back to the base power station,since it allows both derating but also over-generation compared to the base power-station *** solution is applied in a case study of a 50-MW rated oil-fired power station unit at the autonomous system of *** optimal operation of the TES system is investigated,by solving a modified Unit Commitment-Economic Dispatch optimization problem,which includes the TES operating *** results indicate that for most of the scenarios the discounted payback period is lower than 12 years,while in few cases the payback period is 5 years.

This paper focuses on the creation of a dynamic probabilistic model which simulates deterioration trends of a marine engine lubricationsystem. The approach is based on risk and the implementation is achieved through a dynamic Bayesian network (dBN).Risk can be useful for decision making, while dBNs are a powerful tool for risk modelling and prediction models. The model takesinto account deterioration of engine components, oil degradation and the off-line condition monitoring technique of oil analysis, inthe context of predictive maintenance. The paper aims to efficiently predict probability evolution for main engine lubrication failureand to decide upon the most beneficial schemes from a variety of lubrication oil analysis interval schemes by introducing monetarycosts and producing the risk model. Real data and respective analysis, along with expert elicitation, are utilized for achieving modelquantification, while themodel is materialized through a code in the Matlab environment. Results from the probabilistic model showa realistic simulation for the system and indicate the obvious, that with more frequent oil analyses and respective maintenance orrepairs, the probability of failure drops significantly. However, the results from the risk model highlight that the costs can redefinescheme suggestions, as they can correspond to low probabilities of failure but also to higher costs. A two-month interval scheme issuggested, in contrast to the most preferred practice among shipping companies of a three-month interval. The developed model isin general identified as a failure prediction tool focusing on marine engine lubrication failure.
