Exploring non-coding mitochondrial DNA sequences in bryophyte molecular evolution
(2010-04-28)
The thesis presented here focussed on the molecular evolution of non-coding mitochondrial DNA in liverworts and mosses.
To address remaining questions in moss phylogeny, three mitochondrial gene regions were investigated ......

Molecular markers of the mitochondrial genomes of Isopoda and implications on the phylogeny of Peracarida (Crustacea: Malacostraca)
(2010-04-27)
The mitochondrial genome features structural and organizational characters, also referred to as characters of ‘genome morphology’, in addition to primary sequence data. This thesis analyzes the state, evolution, and ...
Regulatorische Funktion der Phosphorylierung von Neprilysin in der Lokalisation an der Plasmamembran und der Interaktion mit dem Tumorsuppressor PTEN
(2010-04-23)
Bei der Zink-Metalloendopeptidase Neprilysin (NEP) handelt es sich um ein Typ 2 Membranprotein, das für die Degradation von extrazellulären Peptiden und Peptidhormonen zuständig ist. Darüber hinaus kann NEP sowohl im ......
Reconstruction of possible realisations of the Late Glacial and Holocene near surface climate in Central Europe
(2010-05-19)
This thesis presents several aspects of reconstructing physical consistent realisations of past climatological fields. Local climate reconstructions are obtained by a method, which is based on the idea of indicator taxa ...
Determination of adsorption and activation volumes and apparent transfer coefficients by pressure and potential modulation
(2010-04-28)
In this thesis the following investigations were carried out on Pt or Pt based electrodes: the determination of the apparent transfer coefficient (α′) for CO oxidation using an ac method, the determination of the molar ...
Nano-Photothermolyse: Eine effiziente Methode zur selektiven Elimination von Zellen in vitro mittels Laser aktivierter Nanogoldpartikel
(2010-04-26)
Durch die Ankoppelung von Nanogoldpartikeln mit Größen von 15 nm und 25 nm an Zellen mittels eines IgG Antikörpers und der anschließenden Bestrahlung mit Nanosekunden Laserpulsen mit einer Wellenlängen von 532 nm lassen ......
Nano-Photothermolysis : An efficient in vitro method for selective cell elimination by laser activated gold nanoparticles
Gold nanoparticles with sizes of 15 nm and 25 nm can selectively target cells ......

Systematic Computational Analysis of Structure-Activity Relationships
(2010-04-20)
The exploration of structure–activity relationships (SARs) of small bioactive molecules is a central task in medicinal chemistry. Typically, SARs are analyzed on a case-by-case basis for series of closely related molecules. ...
Zum Einfluss der Saponine aus Hedera helix L. auf die homologe Desensitivierung des β2-adrenergen Rezeptors und das Relaxationsverhalten der glatten Bronchialmuskulatur
(2010-05-19)
Präparate mit Efeublätter-Trockenextrakt sind zugelassen für die Therapie von akuten und chronischen Krankheiten der Atemwege, die durch eine vermehrte Schleimsekretion und Husten charakterisiert sind. Der Wirkungsmechanismus ...
Die Anthropogeographie Friedrich Ratzels und ihre ideengeschichtlichen Wurzeln
(1956)
Vorliegende Arbeit will im Dienste der Disziplingeschichte eine bisher noch fehlende umfassende, systematische Darstellung der Anthropogeographie Ratzels bieten und ihren ideengeschichtlichen Quellen nachspüren.
Melanoma immunosurveillance by CD4+ T cells
(2021-07-05)
The immune system can recognise and control cancer cells in a process termed cancer immunosurveillance. There is increasing evidence that CD4+ T cells play an important role in melanoma immunosurveillance but ...
