Pure infiniteness, stability and C*-algebras of graphs and dynamical systems
No full textPure infiniteness (in sense of [11]) is considered for C -algebras arising from singly generated dynamical systems. In particular, Cuntz-Krieger algebras and their generalizations, i.e., graph-algebras and OA of an infinite matrix A, admit characterizations of pure infiniteness. As a consequence, these generalized Cuntz-Krieger algebras are traceless if and only if they are purely infinite. In case of graph-algebras of locally finite graphs, stability is characterized by the absence of non-zero unital quotients and bounded trace. Also, graph-theoretical analogues of pure infiniteness and stability are obtained. 1 Introduction Following J. Renault [16] a singly generated dynamical system (SGDS), denoted (X; T ), consists in our setting of a locally compact, second countable Hausdorff space X and a local homeomorphism T from an open subset dom(T ) of X onto an open subset ran(T ) of X . One can associate a locally compact etale Hausdorff groupoid, denoted G(X;T ), that is also amena..

Heritability of Caffeine Metabolism: Environmental Effects Masking Genetic Effects on CYP1A2 Activity but Not on NAT2
No full textHeritability of caffeine pharmacokinetics and cytochrome P450 1A2 (CYP1A2) activity is controversial. Here, we analyzed the pharmacokinetics of caffeine, an in vivo probe drug for CYP1A2 and arylamine N-acetyltransferase 2 (NAT2) activity, in monozygotic (MZ) and dizygotic (DZ) twins. In the entire group, common and unique environmental effects explained most variation in caffeine area under the curve (AUC). Apparently, smoking and hormonal contraceptives masked the genetic effects on CYP1A2 activity. However, when excluding smokers and users of hormonal contraceptives, 89% of caffeine AUC variation was due to genetic effects and, even in the entire group, 8% of caffeine AUC variation could be explained by a CYP1A1/1A2 promotor polymorphism (rs2470893). In contrast, nearly all of the variations (99%) of NAT2 activity were explained by genetic effects. This study illustrates two very different situations in pharmacogenetics from an almost exclusively genetic determination of NAT2 activity with no environmental modulation to only moderate genetic effects on CYP1A2 activity with strong environmental modulation
