Neuropeptides in stress reactivity: Role of enkephalin in response to chronic stress
Melo de Carvalho, Irene (2015-01-29)The incidence of mood pathologies, such as chronic anxiety and major depression, is a serious health problem in modern societies. The knowledge about the molecular mechanisms involved in the development of these disorders ... -
Neuroprotective Effects of Polysialic Acid and SIGLEC-11 in Activated Phagocytic Cells
Shahraz, Anahita (2016-03-30)SIGLEC-11 is an inhibitory receptor expressed on microglial cells and macrophages and can recognize α 2→8 linked Sias structures. The surface of neuron is decorated by different lengths of polySias. PolySia-SIGLEC-11 ... -
Die neurotoxische Wirkung von Sphingosin-1-phosphat: Mögliche Zusammenhänge zwischen Glykosphingolipid-Metabolismus und neurodegenerativen Prozessen
Hagen, Nadine (2010-11-16)Kleinhirnneuronen von S1P-Lyase-defizienten Mäusen und ein synthetischen Sphingosin Analogon wurden in dieser Arbeit verwendet, um die Toxizität von S1P, einem bioaktiven Sphingolipid, in terminal differenzierten Nervenzellen ... -
Neurotransmitter receptors in mouse models of Alzheimer’s disease
von Staden, Elena (2014-06-20)Alzheimer's disease (AD) is the most common form of dementia. The disease occurs in a common sporadic and a familiar form (FAD). Both forms show a very similar clinical and pathological picture, with ß-amyloid (Aß) plaques ... -
Neutral Atom Interactions at Surfaces, in Mixtures and Bose-Condensates
Leung, Vanessa (2007)This thesis presents, through a series of experimental and numerical results, an investigation of the collisional interactions of neutral atoms for topics of technological and scientific interest, namely, atom-surface ... -
A neutral atom quantum register
Schrader, Dominik (2005)In this thesis I present the realization of a quantum register of single neutral atoms, which is a building block of a quantum computer. It consists of a well known number of "qubits" - the quantum analogs of classical ... -
Neutral Pion Electroproduction off Light Nuclei in Chiral Perturbation Theory
Lenkewitz, Mark (2013-12-12)Threshold pion electroproduction on tri-nucleon systems is investigated in the framework of baryon Chiral Perturbation Theory (ChPT) at next-to-leading one-loop order O(q<sup>4</sup>) in the chiral expansion. To this order ... -
New Approach to Arakelov Geometry
Durov, Nikolai (2007)This work is dedicated to a new completely algebraic approach to Arakelov geometry, which doesn't require the variety under consideration to be generically smooth or projective. In order to construct such an approach we ... -
New aspects of deglaciation in southern Norway: Climate variability derived from surface exposure ages of Late Quaternary and Holocene landforms
Marr, Philipp (2020-01-30)The investigation of periglacial and related landforms in South Norway is of high interest for exploring timings of deglaciation and to assess their geomorphological connectivity to palaeoclimatic changes during the Late ... -
New aspects of star cluster physics
Pflamm-Altenburg, Jan (2010-07-22)Star clusters are the birth-sites of both low- and high-mass stars and can be considered to be the building blocks of galaxies. Therefore, the understanding of the formation, evolution, and death of star clusters is of ... -
New bioactive metabolites from the marine-derived fungus Dichotomomyces cejpii and their pharmacological relevance
Harms, Henrik (2015-01-13)Natural products from fungal sources provide an astonishing diversity of bioactive molecules. The secondary metabolite production in fungi is strongly affected by environmental influences and the isolation of fungal strains ... -
A New Continuous 4π-Frozen-Spin-Target for the Crystal Barrel Experiment
Runkel, Stefan (2018-01-29)The CBELSA/TAPS experiment has produced a large amount of data on photo-production reactions in double polarization reactions. For this a frozen-spin target has been used, which consists of a horizontal dilution refrigerator ... -
New inhibitory pathways in CD8 T cell function
Mikulec, Julita (2016-06-07)An adaptive immune response is initiated upon recognition of antigen presented on the surface of antigen-presenting cell (APC) by T cells. CD8 T cells primed in the liver by antigen-presenting liver sinusoidal endothelial ... -
New Insights into Terpene Synthase Catalysis for Rational Enzyme Engineering
Xu, Houchao (2023-11-07)This doctoral dissertation consists of 4 reviews and 16 research articles that present mechanistic studies on terpene biosynthesis. Specifically, sesquiterpenes biosynthetically derived from germacrene A, hedycaryol and ... -
New Insights into the Milky Way Magnetic Fields through Radio Broadband Spectro-polarimetry
Ma, Yik Ki (2020-03-05)Magnetic field is an essential ingredient of the interstellar medium of galaxies. In particular, an accurate characterisation of the magnetic field strength and structure of the Milky Way is crucial for complete understanding ... -
A new methodology to use color spectral data for taxonomic, phylogenetic, and biogeographic studies: An example with three genera of lowland hummingbirds: Topaza, Anthracothorax, and Eulampis
Schmitz Ornés, Angela (2005)I developed a methodology to obtain and compare integral information on bird plumage coloration, using color spectral data to conduct studies on geographic variation, taxonomy and phylogeny of different bird groups. I used ... -
A new molecular mechanism to promote protean agonism at a G protein-coupled receptorl
De Min, Anna (2017-07-24)Protean agonists are of great pharmacological interest as their apparent efficacy may change in magnitude and direction depending on the constitutive activity of a receptor. Yet, this intriguing phenomenon has been poorly ... -
New Results on Abstract Voronoi Diagrams
Bohler, Cecilia (2015-07-21)Voronoi diagrams are a fundamental structure used in many areas of science. For a given set of objects, called sites, the Voronoi diagram separates the plane into regions, such that points belonging to the same region have ... -
