This study investigated the increase in expression in the amygdala of 2 immediate-early genes, c-fos and NGFI-A, following contextual fear conditioning. The immediate-shock freezing deficit paradigm was used to compare rats that received footshock after exploring a context to rats that received footshock immediately after placement in the chamber. The former procedure produces contextual fear c...

Leftward fluid flow in the mouse node is generated by cilia and is critical for initiating asymmetry of the left-right axis. Coiled-coil domain containing-40 (Ccdc40) plays an evolutionarily conserved role in the assembly of motile cilia and establishment of the left-right axis. Approximately one-third of Ccdc40lnks mutant embryos display situs defects and here we investigate the underlying mec...

Mesenchymal stem cells (MSCs) can differentiate into diverse cell types including adipogenic, osteogenic, chondrogenic and myogenic lineages. In the present study, we demonstrated for the first time that sphingosylphosphorylcholine (SPC) induces differentiation of human adipose-tissue-derived mesenchymal stem cells (hATSCs) to smooth-muscle-like cell types. SPC increased the expression levels o...

This paper analyzes the behaviour of U.S. net external position since end Bretton Woods system and examines alternative paths for future adjustment. We estimate a present value expression that relates current imbalance with expected portfolio return differentials exports growth. find will be main channel Half-lives adjustments towards balanced are around 10 years, these having been delayed due ...

In order to identify biomarkers for early diagnosis and/or for therapeutic targets in the delayed health effects of ionizing radiation, we analyzed the subgroups of lymphocytes, serum protein levels and gene expression profiles in the peripheral blood of three ⁶⁰Co γ-ray accidentally exposed persons during the three years after irradiation. Flow cytometry analyses and agarose gel electrophoresi...

Mast cells exhibit a biphasic (immediate and delayed) eicosanoid-biosynthetic response after stimulation with particular cytokines or Fc epsilonRI (high affinity receptor for IgE) cross-linking. Treatment of rat serosal connective tissue mast cells (CTMC) with nerve growth factor (NGF) induced only the delayed phase of PGD2 generation that depended on inducible cyclooxygenase-2 (COX-2), but not...

Declaration I hereby declare that the dissertation entitled " Gene expression data analysis using novel methods: Predicting time delayed correlations and evolutionarily conserved functional modules " submitted to the Department of Biology, Philipps-Universität, Marburg is the original and independent work carried out by me under the guidance of the PhD committee, and the dissertation is not for...
