2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is associated with mammary carcinomas in animals and humans. PhIP is metabolized by CYP 1A1/1A2 and cytochrome b5 reductase, producing free radicals causing DNA strand breaks. Diallyl sulfide (DAS) prevents cancer in animals. We hypothesized that DAS will attenuate PhIP-induced DNA strand breaks and cell death. To test this hypothesis, we t...

Dasatinib (DAS), a second-generation tyrosine kinase inhibitor, is highly effective in treating chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia. However, its clinical use is limited due to serious adverse effects. DAS can disrupt endothelial barrier integrity and increase endothelial permeability which may cause peripheral edema and pleural effusion. A...

Zuverlässige Multicast-Kommunikation spielt für viele Anwendungen eine wichtige Rolle. In dieser Arbeit wird das Endsystem-Multicast-Protokoll Narada, das ursprünglich für das feste Internet entworfen wurde, für den Einsatz in MANETs angepasst. Dazu gehört die Berücksichtigung des gemeinsam genutzten Mediums, eine intelligente Suche von Overlay-Nachbarn und eine verbesserte Metrik zur OverlayOp...

Das ConPlan-Projekt, das am Deutschen Forschungszentrum für Künstliche Intelligenz in Zusammenarbeit mit der SIEDA Systemhaus für intelligente EDV-Anwendungen GmbH Kaiserslautern durchgeführt wurde, beschäftigte sich mit der Repräsentation der Personaleinsatzplanung im Pflegedienst von Krankenhäusern als hierarchical constraint satisfation problem (HCSP). Ergebnis des Projekts ist u.a. das Syst...

BACKGROUND Patient decision aids (DAs) are support tools designed to provide patients with relevant information to help them make informed decisions about their healthcare. While DAs can be effective in improving patient knowledge and decision quality, it is unknown what types of information and evidence are used to populate such decision tools. METHODS Systematic methods were used to identif...
