Zur Rolle von Genen, die in pluripotenten Stadien der Embryogenese von Xenopus laevis exprimiert werden
One of the factors required for the maintenance of pluripotency, characterized by self-renewal and their ability to form all types of tissues, is the mammalian Oct3/4, a member of the POU-V family of transcription factors. ...
Hierarchically organized (hybrid) silica monoliths for the application as stationary phases in HPLC
This work deals with the sol-gel processing by employing diol-modified silanes as precursors towards hierarchically organized (hybrid) silica monoliths. With regard to their application as stationary phases in high performance ...
Effects of glycogen synthase kinase-3 and IkappaB kinase on ligand-dependent activation of the androgen receptor
As PCa is one of the most serious diseases in elderly man, current research focuses on the development of effective new therapies for PCa. Although most patients suffering from PCa initially respond to androgen withdrawal ...
Ioneninduzierte Effekte an metallischen Nanoteilchen
Ion irradiation of metallic nanoparticles (Au, Pt, FePt) on various substrates (SiO2, Si, sapphire) is presented. Nanoparticles were prepared by using inverse micelles of diblock-copolymers as templates. Thus particle ...
Mechanik: Skript zu Grundlagen I der Physik
Einführung in die Experimentalphysik für das 1. Semester Diplom Physik: Mechanik, Relativität, Mechanik starrer Körper, Schwingungen und eindimensionale Wellen
Der Verlust von p53 verhindert das Entfernen von chromosomal-intestinalen Stammzellen in Mäusen mit dysfunktionellen Telomeren
Deletion of components of the DNA-damage signaling pathway can rescue the maintenance and the function of stem cells in aging telomere dysfunctional mice (Choudhury et al; Schätzlein et al.). p53 is activated in response ...
Investigation of the function of the IKK2/NF-kappaB-pathway in c-MYC-induced lymphomagenesis
Prosurvival activity of NF-kappaB is essential for many hematological malignancies like Hodgkins lymphoma (HL), diffuse large B-cell lymphoma (DLBCL), mucosa associated lymphoid tissue (MALT) lymphoma, multiple myeloma ...
Green and sustainable polymers: high-value aliphatic polycarbonates from CO2 and epoxides
The alternating copolymerisation of carbon dioxide (CO2) and propylene oxide (PO) is of high interest for the industry because it enables an excellent technique for the application of cheap and industrially available ...
Charakterisierung von Proteinen des RNA-Metabolismus in Haloferax volcanii
In this thesis three proteins in connection to the cellular RNA metabolism of the model archaeon H. volcanii were investigated for their biological functions. The first project focussed on gaining knowledge about the Lsm ...
Synthese von mesoporösen anorganischen Oxid-Nanopartikeln in Miniemulsion
A novel synthetic approach to mesoporous nanoparticles of various inorganic oxides as silica, titania, and Zr-doped titania has been developed by combining the miniemulsion technique with the sol-gel process. The effect ...
