- Today's heterogeneous embedded systems combine components from different domains, such as software, analogue hardware and digital hardware. The design and implementation of these systems is still a complex and error-prone task due to the different Models of Computations (MoCs), design languages and tools associated with each of the domains. Though making such systems adaptive is technologically feasible, most of the current design methodologies do not explicitely support adaptive architectures. This paper present the ANDRES project. The main objective of ANDRES is the development of a seamless design flow for adaptive heterogeneous embedded systems (AHES) based on the modelling language SystemC. Using domain-specific modelling extensions and libraries, ANDRES will provide means to efficiently use and exploit adaptivity in embedded system design. The design flow is completed by a methodology and tools for automatic hardware and software synthesis for adaptive architectures.

- BACKGROUND: Hepatitis B (HBV) and hepatitis C (HCV) virus infections are major risk factors affecting long-term morbidity and mortality after renal transplantation. Hepatitis prevalence is subject to geographical variations. OBJECTIVE: To compare and analyze the geographical prevalence, risk factors and impact of HBV and HCV infection in multinational cohorts of renal transplant recipients. METHODS: From 1989 - 2002, data on 12,856 kidney transplant recipients in 37 countries were collected within the prospective MOST (Multinational Observational Study in Transplantation). Subgroup analyses of hepatitis-related prevalence, risk factors and impact were conducted on patients whose HBV and HCV status was available at time of transplantation. Countries were substratified according to population prevalence of > or = 5% HBV or > or = 10% HCV. RESULTS: The prevalence of HBV was 2.9%, of HCV 8.7% and of HBV together with HCV 0.4%. Risk factors for hepatitis infection in renal transplant recipients were long dialysis time, retransplantation and blood transfusions. At each study endpoint up to 5 years after transplantation, no significant differences in graft function were observed, although the 1-year acute rejection rate tended to be lower in HCV+ patients. At 5 years post-transplant, there were no differences between the subgroups and regions regarding infections, post-transplant diabetes mellitus or malignancies including PTLD. CONCLUSIONS: Overall, HCV infections are more prevalent than HBV. Despite large geographical differences in prevalence, HBV and HCV status did not appear to have a significant impact on renal graft function, infections, malignancies and post-transplant diabetes mellitus up to 5 years after renal transplantation throughout the MOST countries.
