Recent evidence suggests an involvement of the nuclear receptor NR1i3 (CAR). Fasting induces CAR by largely unknown mechanisms and CAR-deficient mice are defective in fasting adaptation. In rat hepatocytes CAR was induced by WY14643, a PPARalpha-agonist. A DR1 motif in the CAR promoter was necessary and sufficient for this control. The PPARalpha-dependent increase in CAR potentiated the phenobarbital-induced transcription of the prototypical CAR-dependent gene CYP2B1. Since free fatty acids are natural ligands for PPARalpha, a fasting-induced increase in free fatty acids might induce CAR. In accordance with this hypothesis, CAR induction by fasting was abrogated in PPARalpha-deficient mice.}, language = {en} } @article{SchiffersSchurrTielboergeretal.2008, author = {Schiffers, Katja and Schurr, Frank Martin and Tielb{\"o}rger, Katja and Urbach, Carsten and Moloney, Kirk A. and Jeltsch, Florian}, title = {Dealing with virtual aggregation : a new index for analysing heterogeneous point patterns}, issn = {0906-7590}, doi = {10.1111/j.0906-7590.2008.05374.x}, year = {2008}, language = {en} } @article{GermerElsenbeerdeMoraes2006, author = {Germer, Sonja and Elsenbeer, Helmut and de Moraes, Jorge M.}, title = {Throughfall and temporal trends of rainfall redistribution in an open tropical rainforest, south-western Amazonia (Rond{\^o}nia, Brazil)}, issn = {1027-5606}, doi = {10.5194/hess-10-383-2006}, year = {2006}, language = {en} } @article{KonradSchmolkeZackO'Brien2009, author = {Konrad-Schmolke, Matthias and Zack, Thomas and O'Brien, Patrick J.}, title = {Combining thermodynamic and trace element modeling : a tool to quantify mineral reactions and trace element budgets during metamorphism}, issn = {0016-7037}, doi = {10.1016/j.gca.2009.05.009}, year = {2009}, language = {en} } @article{BergerMuellerHoehleetal.2007, author = {Berger, Frauke and M{\"u}ller, Anja and H{\"o}hle, Barbara and Weissenborn, J{\"u}rgen}, title = {German 4-year-olds comprehension of sentences containing the focus particle "auch" (also) : evidence from eye- tracking}, year = {2007}, language = {en} } @book{Gronau2007, author = {Gronau, Norbert}, title = {Approach for requirement oriented team building : eChallenges 2007}, publisher = {Univ.

We describe here the generation of a panel of monoclonal antibodies to native and heat inactivated GOD. One of the hybridomas, E13BC8, was used for cloning of a single chain antibody (scFv). This scFv was expressed in Escherichia coli XL1-blue with the help of the vector system pOPE101. The scFv was isolated from the periplasmic fraction and detected by western blotting. It reacts specifically with soluble active GOD but does not recognize denatured GOD adsorbed to the solid phase.

After cloning the variable genes into a phage vector a functional antibody fragment was selected by phage display panning. Recombinant antibody could be expressed as phage antibody and as soluble single chain antibody in Escherichia coli. High yield of scDE1 could also be detected in bacterial culture supernatant. The scDE1 showed the same binding specificity as the parental monoclonal antibody, i.e. it bound fluorescein, fluorescein derivatives and a fluorescein peptide mimotope. Surface plasmon resonance revealed a K(D) of 19 nM for the scDE1 compared to 0.7 nM for the monoclonal antibody. The isolated soluble scDE1 could easily be conjugated to horseradish peroxidase which allowed the use of the conjugate as universal indicator for the detection of fluorescein-labelled proteins in different immunoassays. Detection of hCG in urine was performed as a model system using scDE1. In addition to E. coli the scFv genes could also be transferred and expressed in eukaryotic cells.

BALB/c mice immunized with adjuvant-free VLPs developed VP1- and epitope-specific antibodies. The level of the CEA-specific antibody response was determined by the insertion site, the number of inserts, and the flanking linker. The strongest CEA-specific antibody response was observed in mice immunized with VP1 proteins harboring the CEA insert at site 1. Moreover, the CEA- specific antibodies in these mice were still detectable 6 mo after the final booster immunization. Our results indicate that hamster polyomavirus-derived VLPs represent a highly immunogenic carrier for foreign insertions that might be useful for clinical and therapeutic applications.}, language = {en} }
