Loss of Inhibitory CD33 Signaling Results in Increased Microglial Activation
(2021-06-23)
CD33 is expressed on immune cells of myeloid origin, such as macrophages and microglia. Upon activation, CD33 recruits and activates protein tyrosine phosphatases, which results in attenuation of the activatory signaling ...
Simulation of Bone Remodeling Process around Dental Implant During the Healing Period
(2021-07-05)
This interdisciplinary thesis deals with the numerical investigation of bone remodeling around dental implants during the healing period with regard to biomechanical aspects. The aim of the study was to develop algorithms ...
Influence of the St. John's Wort Extract Ze117 on the Lipidome of PBMC and on the Lateral Diffusion of ß1-Adrenergic Receptors in C6 Cells
(2021-03-18)
Stress causes pathological changes in the signal transduction of neurotransmitter systems, which can lead to depression. Signaling relies not only on receptor-ligand interactions and subsequent regulatory processes, but ...
Weak lensing magnification & baryon acoustic oscillations in galaxy-galaxy lensing
(2021-09-08)
Cosmology is the science that aims to explain the Universe in its entirety. While the standard cosmological model has had tremendous success in explaining independent astrophysical observations, we still lack understanding ...
Geometric three-dimensional modelling of tectonic structures in the Alps and Jura Mountains
(2021-06-01)
Geometric and kinematic three-dimensional (3D) modelling of complex geological structures experienced an outstanding evolution and has become more and more important nowadays in the field of geoscience as well as oil and ...
Experimental Near-Field Characterization of Plasmonic Nanostructures
(2021-01-13)
The spatial resolution of conventional optical technologies is fundamentally limited by diffraction due to the wave nature of light. A promising platform to overcome this diffraction limit in nanophotonic applications is ...
Diversity of regulatory systems and their contribution to colistin and tigecycline resistance in Acinetobacter baumannii
(2021-12-06)
Acinetobacter baumannii is a nosocomial pathogen which causes a wide range of serious infections in critically ill patients in the intensive care unit. Besides its high desiccation tolerance, the ability to form biofilms, ......
Effect of osmotic stress on barley leaf cuticles
(2021-07-19)
Assessing the drought stress tolerance at the seedling stage is an important trait as it later affects the growth and grain yield. The leaf and root characteristics are mainly focused on during this seedling stage. The ...
Transient Non-Line-of-Sight Imaging
(2021-05-05)
Sight is perhaps the most important sense of the human species. But while it allows us to gain a near-instant understanding of our surrounding, it has a fundamental limitation: An object can be hidden from view if it is ......
Das Sehen ist die vielleicht wichtigste Sinneswahrnehmung des Menschen. Es erlaubt uns in Sekundenbruchteilen unsere Umgebung einschätzen zu können, hat dabei jedoch eine fundamentale Einschränkung: Ein Objekt kann nicht ......

Metabarcoding Invertebrate Communities in a Natural Park: From Methods to Diversity Patterns
(2021-02-22)
Biodiversity is worldwide suffering from a dramatic decline, whose underlying causes are still fairly unknown. The scientific investigation and identification of potential drivers of biodiversity loss are strongly hampered ...
