BACKGROUND Elevated fasting levels of total homocysteine are now accepted as an independent risk factor for the development of arteriosclerotic vascular diseases. A polymorphism in the gene encoding methylenetetrahydrofolate reductase (MTHFR), caused by the C677T point mutation, leads to increased thermolability of the enzyme, with reduced enzyme activity.(More)
Slow acetylators of the polymorphic N-acetyltransferase 2 (NAT2, EC suffer more often from side-effects of NAT-substrates than fast acetylators. Since concomitant administration of drugs may inhibit NAT2, we studied the influence of acetaminophen on NAT2 in human hepatic cytosol in vitro and in healthy individuals. In-vitro acetylation was assessed(More)
BACKGROUND The 677C-->T polymorphism of methylenetetrahydrofolate reductase can lead to increased homocysteine. Moderate increases of homocysteine can be lowered by folic acid (0.4-10 mg day-1). This study compared the effect of folic acid with 5-methyltetrahydrofolate, the active form of folate generated by this reductase, on homocysteine levels in healthy(More)
This paper provides an approach to assessing Quality of Context (QoC) parameters in a ubiquitous Ambient Assisted Living (AAL) environment. Initially, the study presents a literature review on QoC, generating taxonomy. Then it introduces the context management architecture used. The proposal is verified with the Siafu simulator in an AAL scenario where the(More)
