Abstract—Boolean networks are considered generic models for a large class of asymmetric networks, such as neural networks or gene regulatory networks. Previous work has shown that such networks...

Tumor Promotion in Liver of Mice with a Conditional Cx26 Knockout (2008)

Marx-Stoelting, Philip, Mahr, Johanna, Knorpp, Thomas, Schreiber, Sandra, Templin, Markus F., Ott, Thomas, ...

Connexin (Cx) 26 and 32 are the major gap junction proteins in liver. We recently demonstrated that Cx32 is essential for phenobarbital (PB)–mediated tumor promotion in mouse liver. To investigate...

Infrared imaging and spectroscopy of companion candidates near the young stars HD 199143 and HD 358623 in Capricornius (2002)

Neuhaeuser, Ralph, Guenther, Eike, Mugrauer, Markus, Ott, Thomas, Eckart, Andreas

We present JHK images of the young (~20 Myrs) nearby (~48 pc) stars HD 199143 and HD 358623 to search for (sub-)stellar companions around them. The images were obtained in JHK with the speckle camera...

Imaging and spectroscopy of DENIS-P J104814-395606 (2002)

Neuhaeuser, Ralph, Guenther, Eike, Alves, Joao, Grosso, Nicolas, Leinert, Christoph, Ratzka, Thorsten, ...

We obtained deep H- and K-band images of DENIS-P J104814-395606 using SofI and the speckle camera SHARP-I at the ESO-3.5m-NTT as well as QUIRC at the Mauna Kea 2.2m telescope between December 2000...

Morphology and morphometric investigation of hepatocellular preneoplastic lesions and neoplasms in connexin32-deficient mice (2002)

Evert, Matthias, Ott, Thomas, Temme, Achim, Willecke, Klaus, Dombrowski, Frank

Gap junctions are composed of protein subunits, called connexins, and provide a pathway for the exchange of ions and small molecules between contacting cells. This transfer of molecules is thought to...

The Sgr A* Stellar Cluster: New NIR Imaging and Spectroscopy (1999)

Eckart, Andreas, Ott, Thomas, Genzel, Reinhard

We report preliminary results based on new near-infrared observations of the central stellar cluster of our Galaxy conducted with the infrared spectrometer ISAAC at the ESO VLT UT1 and the MPE...

Sequential superparamagnetic clustering: Tracking down the most natural clusters (1101)

Thomas Ott, Albert Kern, Ausgar Schuffenhauer, Maxim Popov, Pierre Acklin, Edgar Jacoby, ...

For the clustering of chemical structures that are described by the Similog, ISIS count, and ISIS binary fingerprints, we propose a sequential superparamagnetic clustering approach. To appropriately...

A novel mammalian receptor for the evolutionarily conserved type II GnRH

Millar, Robert, Lowe, Steven, Conklin, Darrell, Pawson, Adam, Maudsley, Stuart, Troskie, Brigitte, ...

Mammalian gonadotropin-releasing hormone (GnRH I: pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2) stimulates pituitary gonadotropin secretion, which in turn stimulates the gonads. Whereas a...

Essential myosin light chain as a target for caspase-3 in failing myocardium

Moretti, Alessandra, Weig, Hans-Jörg, Ott, Thomas, Seyfarth, Melchior, Holthoff, Hans-Peter, Grewe, Diana, ...
