Wolfspinnenzönosen (Araneae, Lycosidae) von Weinbergsstandorten bei Bad Honnef und Unkel und ihre ökologische Differenzierung
(2003)
Objective of this study was to analyse autoecological and synecological factors and diversity of spider populations in vineyards of the Rhine-area near Bonn/Germany. In addition the impact of plant cover and species density ...
Taxonomy, Phylogeny, and Biogeography of the Hummingbird Genus Thalurania GOULD, 1848 (Aves: Trochilidae)
(2003)
A taxonomic revision of the genus Thalurania was carried out based on plumage coloration and morphometric data. Variance in these data was assessed across the whole range of each species. A new methodology of plumage ...
Schwerkraftwahrnehmung des Ciliaten Stylonychia mytilus: Elektro- und verhaltensphysiologische Untersuchungen
(2003)
Unter Anwendung von verhaltens- und elektrophysiologischen Methoden wurden Versuche zur Schwerkraftwahrnehmung des hypotrichen Ciliaten Stylonychia mytilus durchgeführt. Es konnte gezeigt werden, dass die Zelle in ...
Biochemical characterization of the human Cyclin-dependent kinases Cdk7 and Cdk10
(2021-08-13)
Protein kinases comprise a large superfamily of enzymes regulating a plethora of cellular processes. Dysregulation of protein kinases, such as loss of activity, hyperactivity or mislocalisation, is often accompanied with ...
Role of innate lymphoid cells in type 1-dominated experimental Plasmodium berghei ANKA and type 2-dominated Litomosoides sigmodontis infection
(2021-10-27)
Malaria and filariasis remain among the biggest health problems in the tropics and subtropics, especially in Africa, and in the case of malaria among the ten most frequent causes of death. The parasites that cause malaria ......
Characterization of polygalacturonase inhibitor 1-like protein (CpPGIP) from Craterostigma plantagineum and analysis of stress inducible pcC13-62 promoters to understand desiccation tolerance in Linderniaceae
(2020-09-02)
The work is divided into two major parts. The first part is the characterization of an important cell wall protein “polygalacturonase inhibitor 1-like protein (CpPGIP)” and in the second part we studied “stress inducible ......
Single cell visual psychophysics
(2021-10-05)
On the one hand, the eye is the human being’s window to the world. On the other hand the eye is a window to the human brain enabling noninvasive and in vivo assessment of nervous tissue. With adaptive optics scanning laser ...
Comparative analysis of the insect mobile genetic element repertoire and its influence on genome size dynamics
(2020-06-10)
This thesis presents comparative genomics studies in insects as well as bioinformatics software development. Its empirical research part is focused mainly on mobile genetic elements, also termed transposable elements. The ......
Investigations on the early biosynthetic steps of griseorhodin A
(2012-05-03)
Presented here are the results concerning the early biosynthesis of the telomerase inhibitor griseorhodin A.
The griseorhodin biosynthetic gene cluster encodes components of a type II polyketide synthase (PKS). The ......

PPARγ in myeloid cells controls CNS autoimmunity
(2012-03-12)
The nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-activated transcription factor that regulates the immunogenicity of myeloid cells such as dendritic cells (DCs), macrophages, and ......
