A2B-Adenosin-Rezeptor-Homo- und Heterodimere: Biolumineszenz-Resonanz-Energie-Transfer-Studien und pharmakologische Charakterisierung
(2012-12-12)Die Adenosin-Rezeptoren, welche zur Superfamilie der G-Protein-gekoppelten Rezeptoren (GPCR) gehören, werden in die vier Subtypen, A1, A2A, A2B und A3 unterteilt. Aufgrund der ... -
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 ... -
Ab-initio Untersuchungen an frühen Ausscheidungsphasen der Aluminium(-Magnesium-)Kupfer-Legierungen
(2015-07-23)Frühe Ausscheidungscluster der AlCu-Legierungen und der AlMgCu-Legierungen werden mit numerischen ab-initio Methoden mit Hilfe des DFT-Programmcodes SIESTA untersucht. Cu-Atome favorisieren innerhalb der AlCu-Legierungen ... -
ABA-Dependent and -Independent Regulation of Tocopherol (Vitamin E) Biosynthesis in Response to Abiotic Stress in Arabidopsis
(2019-05-15)Abiotic stresses in plants lead to elevated levels of reactive oxygen species that can have detrimental effects on photosystems and thylakoid lipids. To limit damage, plants increase the production of antioxidants such as ... -
Abbildende Spektroskopie erosionsrelevanter Bodenparameter in Agrarökosystemen
(2013-01-23)Die Vielzahl der Funktionen, die der Boden in einem Ökosystem übernimmt, verleiht ihm einen hohen Stellenwert im Mensch-Umwelt-System. Der Boden landwirtschaftlicher Nutzflächen ist im Besonderen eine elementare Säule der ... -
Absorptions- und Emissionsspektroskopie an superkritischem, flüssigem und gasförmigem Xenon im Vakuum-Ultravioletten Spektralbereich
(2019-02-05)Seit 120 Jahren ist die Existenz des schwersten stabilen Edelgases, Xenon, bekannt. In dieser Zeit haben eine Vielzahl an Arbeiten mittels Spektroskopie seine Eigenschaften untersucht. Heutzutage findet sich Xenon in ... -
Acceleration of microglial clearance function by small TREM2-activating anionic disaccharides
(2014-07-29)Triggering receptor expressed on myeloid cells-2 (TREM2) is an innate immune receptor, which is expressed on myeloid cells, like microglia inside the central nervous system. TREM2 signals via the adaptor protein DAP12. ... -
Accumulation and Clearing of Ions in Circular Electron Accelerators
(2020-09-02)Modern sychrotron light sources have to provide stable storage for electron beams with high charge densities to make brilliant synchrotron radiation available to users. Since requirements on the brilliance of the radiation ... -
Accurate Ground Penetrating Radar Numerical Modeling for Automatic Detection and Recognition of Antipersonnel Landmines
(2013-11-14)Ground penetrating radar (GPR) is a promising non-invasive technology for imaging shallowly buried low-metal or non-metallic antipersonnel (AP) landmines. However, the application of GPR to the landmine problem remains ... -
Acquisition, Transmission and Rendering of Objects with Optically Complicated Material Appearance
(2015-12-10)A major goal in computer graphics is the generation of photorealistic images. Nowadays, the degree of realism is often not restricted by the rendering algorithm but instead mainly depends on the quality of the virtual scene ... -
Actin cytoskeleton and endomembrane system dependent cell growth
(2008)In plants, membrane recycling processes are involved in every instance of cell volume changes which occur during growth, development and adaptation to the environment. The thesis work described here addresses membrane ... -
Actin Regulatory Proteins in Dendritic Arborisation Neurons of Drosophila
(2019-10-23)Dendrites are highly branched extensions of nerve cells, along which signals are received and propagated to the cell body. The correct morphology of dendrites is essential for the function of the nervous system. The ... -
Action of zona pellucida glycoproteins in mouse and human sperm
(2017-08-22)For fertilization, sperm have to penetrate the oocyte’s vestment, the zona pellucida (ZP). In mouse and human, the ZP consists of three or four different ZP glycoproteins, respectively. Binding of sperm to ZP glycoproteins ... -

Active Plasmonic and Dielectric Nanoantennas
(2017-08-10)This thesis presents results on the fabrication, investigation and characterization of active optical nanoantennas. The three partial results in order of their occurrence are: (i) The demonstration of the operational ... -
Activity patterns in the septal-hippocampal network predict voluntary locomotion
(2018-07-13)In the brain of animals, locomotion is encoded and represented in multiple ways. During locomotion, the hippocampus (HC) displays characteristic activity patterns that change from asynchronous states when the animal is ... -
Activity-Dependent Regulation of Neuronal Ion Channel Expression During Epileptogenesis
(2005)Status epilepticus (SE) is known to cause numerous structural and functional alterations in brain. In this study, expression of various voltage-gated ion channels in rat hippocampal CA1 neurons were investigated at different ... -
The Acyl-ACP Thioesterase FatM from Lotus japonicus is involved in lipid transfer during Arbuscular Mycorrhiza Symbiosis
(2020-01-27)Arbuscular mycorrhiza colonization of roots is an ancient symbiosis that presumably was involved in the conquest of the land by early plants. Its main benefit for plants is the increased access to soil mineral nutrients ... -
Adaptation primärer Afferenzen und Hirnstammneuronen im Seitenliniensystem des Goldfisches, Carassius auratus, auf sequenzielle Reize
(2016-07-29)Weltweit sind ca. 33.000 Fischarten beschrieben, die sich in ihren Lebensraumansprüchen und in ihrer Lebensweise oft deutlich voneinander unterscheiden. Alle bisher beschriebenen Fische und aquatisch lebende Amphibien ... -
Adaptations of the four-striped field mouse (Rhabdomys pumilio, Sparman 1784) to the Namib Desert
(2003)Animals living in arid conditions need to adapt to a number of environmental factors, namely intense solar radiation, extreme temperatures, low humidity, (dry) winds, and temporal and spatial unpredictability of both water ...
