Phenotyping of barley resistance to plant diseases on the leaf and greenhouse scale through hyperspectral imaging and data analysis
(2021-05-17)
Optical sensors become increasingly interesting as means to perform automated, non-invasive and objective monitoring in agriculture, but also have immense potential as tools for research and development. Especially ...
A role of Alzheimer’s disease-associated γ-secretase in lipid metabolism and lipid droplet formation via LXR activation
(2021-06-29)
The γ secretase is an intramembrane protease complex, essential for the processing of a wide variety of type-1 membrane proteins. Among these is the amyloid precursor protein (APP), a protein strongly linked to Alzheimer’s ...
Synthesis and reactions of Janus-type bis(NHCs), tuned by phosphorus bridges
(2021-02-15)
Due to our first attempts to synthesize P-functional bis(NHCs),[6] we were aware of a problem if bis(thiones) were used. Therefore, the idea emerged to use bis(selones) instead. Herein, the synthesis of the first tricyclic ...
Investigating 5-HT2A receptors - Development of a fluorescent 5HT2A receptor agonist and elucidation of the effects of St. John's wort extract STW3-IV, hyperforin and hyperoside on 5HT2A receptors

The Influence of Solvent Reorganization on Organocatalytic Reactions
(2021-04-07)
In the last decades N-heterocyclic carbenes have shown a certain potential as organocatalysts. In addition to the formation of regio- and stereoselective C-C coupling reactions, their scope of application includes the ...
Applying Disaster Risk Governance in Dynamic Environments: Case study Rio de Janeiro State, Brazil
(2021-05-17)
Between 1980 and 2015, around 1.6 billion people were killed in meteorological, geophysical, hydrological or climatological disasters. Future annual losses are estimated to reach US4 billion in the built environment alone. ...
Characterization of the hyperpolarization-activated, highly-selective proton channel HCNL1 found in the sperm of the zebrafish Danio rerio
(2021-04-29)
Zebrafish are external fertilizers and release their gametes into the surrounding water. Yet, the freshwater environment with its low osmolarity poses a challenge for the gametes. Given these unique ion conditions, it seems ......
Charakterisierung des hyperpolarisationsaktivierten, hochselektiven Protonenkanals HCNL1 im Spermium des Zebrafischs Danio rerio
Zebrafische pflanzen sich durch externe Befruchtung fort und geben ......

Pattern Recognition in Intracranial EEG Signals and Prediction of Memory
(2021-03-12)
This thesis presents a method for pattern recognition in neurocognitive data, in particular intracranial electroencephalographic (iEEG) data. The approach aims to reveal mechanisms underlying cognitive processes. This means ...
Targeted Fast Radio Burst Searches with the Efflesberg 100-m Radio Telescope
(2021-03-24)
Fast radio bursts (FRBs) are bright, energetic, millisecond duration radio bursts of extragalactic origin. The source of FRBs still remains an open problem. Since the discovery of FRBs in 2007, over 100 FRBs have been ...
Molecular Mechanisms of NLRP3 Inflammasome Activation: Involvement of the Leucine-Rich Repeat Domain and Charcot-Leyden Crystals
(2021-07-29)
Chronic inflammation is a major driver of several non-communicable diseases. The cytosolic pattern recognition receptor NLRP3 is involved in the development of many of these diseases, as its activation in innate immune ...
