From cell penetrating peptides to peptoids and polyamines as novel artificial molecular transporters: Entwicklung neuer Delivery-Strategien für siRNAs ; Von zellpenetrierenden Peptiden zu Peptoiden und Polyaminen als neuartige molekulare Transporter
(2005)
In recent years, RNA interference has gained a lot of importance as a tool for posttranscriptional silencing of genes due to its high specificity, efficiency and ease of application. In mammalian cells RNAi is triggered ...
Pyrolyse von Metalloxiden und Silikaten unter Vakuum mit konzentrierter Solarstrahlung
(2005)
In der vorliegenden Arbeit wurde untersucht, ob eine solarthermische Hochtemperaturpyrolyse von Mondgestein oder anderen Gesteinen im Vakuum zur Gewinnung von Sauerstoff prinzipiell möglich ist und welche Anforderungen ...
Systematics and Biogeography of the African Scaly-tailed Squirrels (Mammalia: Rodentia: Anomaluridae)
(2005)
The aim of the present investigation was a better understanding of the systematics and biogeography of the African scaly-tailed squirrels. Therefore 1581 anomalurid specimens from 22 collections were examined and data from ...
Untersuchungen zur Funktion von BAT3-Spleißvarianten
(2005)
BAT3 und BAT2 sind zwei benachbarte Gene in der MHC Klasse III-Region. In der vorliegenden Arbeit wurden BAT3-Spleißvarianten hergestellt und mit molekular-biologischen sowie biochemischen Methoden untersucht. Ausgehend ...
Changing distribution patterns of selected conifers in the Quaternary of Europe caused by climatic variations
(2005)
Extreme climatic variations in the Quaternary of Europe did not only lead to an intense reduction of plant diversity, but also to significant changes in plant distribution. It is the aim of this work to exemplary investigate ...
Methotrexate-induced biochemical alterations of the folate and methyl-transfer pathway in the CNS
(2005)
Methotrexate (MTX), administered as high-dose infusion (3-5 g/m2) and/or intrathecally (3-12 mg) has been associated with neurotoxicity of unclear pathogenesis. It was investigated if the biochemical alterations ...
Complexity Bounds on Some Fundamental Computational Problems for Quantum Branching Programs
(2005)
We study quantum computational complexity of several problems connected to the Hidden Subgroup Problem. This problem drew substantial attention when a polynomial time quantum algorithm for it was found. The algorithm ...
Ab-initio Untersuchungen an Aluminium, seinen Defekten und Aluminium-Legierungen
(2005)
Ziel dieser Arbeit war die Untersuchung von Kristallstrukturen und deren Defekte in Hinblick auf die experimentelle Nachweisbarkeit mit Positronenlebensdauer - Spektroskopie. Die Untersuchungen der Kristallstrukturen wurden ...
Dense Cores in Galactic Cirrus Clouds
(2005)
In this thesis I study the formation and evolution of dense cores in cirrus clouds. Cirrus clouds are diffuse and translucent molecular clouds widely spread within the galaxy. Dense cores in molecular clouds are the locations ...
Laser Manipulation of Indium Atoms
(2005)
This thesis presents experiments on laser cooling of an indium atomic beam. The long-term goal of this experiment is to deposit indium atoms on a substrate using a standing wave light mask. The atomic beam has to be initially ...
