oncogenic RNA viruses. It has also been reported (24) that single-stranded polyribonucleotides at very low concentrations inhibit DNA polymerase of Rauscher leukemia virus. In this report, we present data that show a way in which RNA indirectly affects DNA synthesis. These data show that RNA markedly inhibits ribonucleotide reducÃ-asefrom Ehrlich ascites tumor cells, at concentrations which cou...

This paper describes a national eHealth platform concept with a multi-level privacy protection in order to improve the security and privacy of medical information on their storage locations as well as during the exchanging/sharing processes. The key idea is to classify and split-up data into different servers. A Trusted Third Party server manages personal identifying data together with the rela...

Lel G be a graph with vertex connectivi2y k(G). An important measure of the fault tolerance of G is its faul&diameler df(G), which is defined as the maximum diameter resulting from the deletion of any set of nodes containing less than k(G) nodes. The robustness of G is often measured by comparing d/(G) with the diameter of Ihe fault-free G, namely d(G). In particular, a family of graphs G, is d...

The healthcare industry is the largest industry in the US, and costs are growing rapidly. There is also an increase in waste, medical errors and patient injuries. One central problem is that hospitals have compartmentalized and disaggregated business models in which clinical specialists duplicate information. An international project called Integrating the Healthcare Enterprise (IHE) is underwa...

March 2000 39 medicamundi This article addresses various aspects of the integration of imaging systems and information systems in the radiology department and the hospital as a whole. It includes the technical and organizational obstacles, the role of standards, and some promising recent developments for overcoming the obstacles. Particular attention is paid to the IHE (Integrating the Healthca...

AerMet 100 is a new generation ultrahigh-strength steel (UHSS) and is currently specified for manufacturing important aircraft parts such as landing gears. As a UHSS, AerMet 100 is susceptible to internal hydrogen embrittlement (IHE) and the mechanisms are complicated due to the trapping H transport interactions, given the fine-scale microstructural features serving as potential trap sites (dis...

Ensuring patient safety inmedical device networks bymanaging alarms and related clinical data is a lifecritical issue. The Integrating the Healthcare Enterprise (IHE) initiative emerged to discuss and solve the interoperability and integration problems among medical information systems, vendors and users in order to improve patient care and healthcare system dependability. This paper models and...

OBJECTIVE We assessed primary care providers' perception of a health information exchange system (HIE) based on IHE XDS in the metropolitan area of Braunschweig, Lower Saxony, Germany. DESIGN An application enabling access to medical documents in an XDS Affinity Domain was developed. We examined usability and factors related to user acceptance. MEASUREMENTS User perception was probed using ...

Developing software f o r distributed Computing systems is challenging due t o lack of effective software development methodologies and iools. In particular, because many errors in ihe source code can be traced to the errors in the requiremenis specification, it i s especially important to have effeciive verification techniques f o r the requiremenis specification. In this paper, an approach io...
