The Herpetofauna of the Peruvian dry forest along the Andean valley of the Marañón River and its tributaries, with a focus on endemic iguanians, geckos and tegus: Squamata: Iguanidae, Phyllodactylidae, Teiidae
(2014-02-27)
The present study was organized to contribute to the knowledge of the herpetofauna of the Inter-Andean dry forest valleys. Several field surveys were conducted between July 2005 and November 2010 at 22 different localities ......
Molekulargenetische Untersuchungen bei uro-rektalen Fehlbildungen
(2014-02-07)
Zu den schwersten angeborenen uro-rektalen Fehlbildungen zählen der Blasenekstrophie-Epispadie-Komplex (BEEK) und anorektale Malformationen (ARM). BEEK wird klinisch hinsichtlich seines Schweregrades in drei verschiedene ......
Young stellar clusters throughout the Galaxy and the interaction with their molecular environment
(2014-02-28)
Stars are born within dense clumps of giant molecular clouds, constituting young stellar agglomerates known as embedded clusters. Once the parental gas is expelled through stellar feedback, they evolve into bound open ...
Physikochemische und biochemische Mechanismen in der Plasmamembran zur Kontrolle des Clusterverhaltens des T-Zell-Rezeptors
(2014-02-26)
Die Plasmamembran als Vermittlerin zwischen Zellinnerem und umgebender Umwelt ist eine wichtige Struktur der Zelle, deren Organisationsprinzipien nur ansatzweise verstanden sind. Membranproteine erfüllen essentielle Aufgaben ......
Effective Field Theory for Halo Nuclei
(2014-03-07)
We investigate properties of two- and three-body halo systems using effective field theory. If the two-particle scattering length a in such a system is large compared to the typical range of the interaction R, ...
Funktionelle neuroanatomische Analyse eines nahrungsabhängigen Schaltkreises in Drosophila melanogaster
(2014-03-13)
Eine weltweit zunehmende Fehlernährung und die damit verbundenen Stoffwechselerkrankungen wie Diabetes haben die Aufklärung neuropeptiderger Systeme vorangetrieben, die an einer Regulation der Nahrungsaufnahme beteiligt ......
Cut Cell Methods in Global Atmospheric Dynamics
(2014-02-28)
In this thesis, we study next generation techniques for the numerical simulation of global atmospheric dynamics, which range from modeling and grid generation to discretization schemes.

Effects of space-relevant radiation on pre-osteoblasts
(2014-02-28)
Until now limited research has been conducted to address the mechanisms leading ionizing radiation exposure induced bone loss. This is relevant for cancer radiotherapy and human spaceflight. Exposure to radiation can result ...
The implication of microglial sialic acid-binding immunoglobulin-like lectin-E (Siglec-E) in neuroinflammation
(2014-03-07)
Microglia are the resident immune cells of the central nervous system (CNS). They display a whole set of recognition receptors on their cell surface to sense intact or lesioned cells in the CNS. A subfamily of these receptors ...
Chemisch-molekularbiologische Studien zur Substratspezifität von Ketosynthase-Domänen in trans-AT-Polyketidsynthasen
(2014-01-14)
Im Rahmen dieser Arbeit wurde die Substratspezifität verschiedener trans-AT Ketosynthasen untersucht und Oligomere für das ARCUT-basierte Schneiden der Psymberin-DNA synthetisiert. Weiterhin wurden Substrate für die ...
