O-GlcNAc – a posttranslational modification implicated in Alzheimer disease?
(2015-04-22)O-linked N-acetylglucosamine (O-GlcNAc) is a highly dynamic posttranslational modification which has been found on a myriad of nucleocytoplasmic proteins. O-GlcNAc addition and removal are catalyzed by two conserved enzymes, ... -
Oberflächen als Übertragungswege für Salmonellen in der Fleischgewinnung beim Schwein
(2006)Gegenstand der vorliegenden Arbeit ist die Darstellung einer möglichen Beteiligung Produkt berührender Oberflächen der Fleischgewinnung beim Schwein an der Verteilung von Salmonellen über die Prozesslinie hinweg. Über einen ... -

(2009-09-03)Oberflächencharakterisierung von III-V MOCVD-Filmen aus heterozyklischen Single Source Precursoren In vielen mikro- und optoelektronischen Bauteilen finden Antimon-haltige Verbindungshalbleiter Verwendung. Insbesondere ist ... -
Oberflächenmikrostruktur von Zahnhartgeweben nach Bestrahlung mit unterschiedlichen Lasersystemen: eine Pilotstudie unter Nutzung der AFM-Technologie
(2016-06-30)Ziel der vorliegenden Studie war die Analyse der Oberflächenmikrostruktur von Zahn-hartgewebe nach Bestrahlung mit insgesamt 4 unterschiedlichen, zum Teil neuartigen Lasersystemen unter anderem mithilfe der Rasterkraftmikroskopie ... -
Oberflächenmodifizierung von Lactose mit überkritischem CO2
(2003)In der pharmazeutischen Industrie gewinnen die Mikronisierung und die Oberflächenbehandlung mit überkritischen Fluiden immer mehr an Bedeutung.
Ein Stoff wird zum überkritischen Fluid, wenn Druck und Temperatur über ... -
Obesity impairs virus-specific memory CD8+ T cell signalling and function
(2024-04-11)The main function of the immune system is to protect the host against invading pathogens. Immunological memory is formed after a primary infection and serves to provide protection in a fast and vigorous manner upon secondary ... -
Objective and quantitative methods in the study of dinosaur tracks
(2019-02-05)This dissertation develops and employs objective and quantitative methods for the analysis of dinosaur tracks. Tracks are—besides the familiar bones and teeth—a crucial data source for inferences on dinosaur biology and ... -
Observation of top quark pair production and estimation of W+jets background with ATLAS at the LHC
(2010-12-22)An analysis has been presented based on an integrated luminosity of 2.9 pb-1 of 7 TeV center-of-mass energy proton-proton collision data in ATLAS at the Large Hadron Collider. The data have been collected since ... -
Observation of W → τντ Decays with the ATLAS Experiment
(2011-05-04)Physics studies of processes with t leptons in the final state, while challenging at hadron colliders, are of great importance at the LHC. The τ leptons provide important signatures in searches for the Higgs boson as well ... -
Observations of the Sunyaev-Zel'dovich Effect towards Clusters of Galaxies with the APEX Telescope
(2009-09-14)Results of 150 GHz continuum observations of several X-ray bright clusters of galaxies in the Sunyaev-Zel'dovich (SZ) effect, carried out using the APEX-SZ bolometer array on the APEX telescope, are presented. Follow-up ... -
Obstruction theory for operadic algebras
(2012-05-21)We study obstruction theory for formality of chain operadic algebras. We construct a canonical class γA for an algebra A over a cofibrant chain operad P∞. This class takes values in the Gamma cohomology ... -
Occasional direct-seeding of grain legumes in Organic Agriculture in Germany and Brazil: fertilisation with P and S & weed control with natural herbicides
(2018-02-13)The aim of this work was to test strategies, which improve nutrient supply and weed control in occasional direct-seeded (DS) grain legumes in Organic Agriculture. The effect of intra-row fertilisation of rock phosphate ... -
Occlusion and Function of Triconodont Dentitions
(2020-12-18)Over the last decades, many studies have focused on the tribosphenic molar and its functional aspects because it is considered to be a key innovation in mammalian evolution. Early triconodont dentitions have been examined ... -
Ocular Onchocerciasis: The Role of Toll-Like Receptor-2 and Interferon-γ
(2010-03-17)River Blindness is still highly prevalent in subsaharan Africa with millions of people suffering from the infection with Onchocerca volvulus. This filarial worm harbors the endosymbiont Wolbachia which was ... -
Oculomotor Biomarkers in Trait and State Model: Systems of Psychosis
(2018-02-21)Antipsychotic drugs are highly effective in reducing positive symptoms of psychosis. However, despite major efforts, negative and cognitive symptoms are still not sufficiently treatable. Importantly, these symptoms have ... -
Odor-evoked modulation of the olfactory bulb by projections from the horizontal limb of the diagonal band of Broca
(2021-07-09)Olfactory input encodes essential information about the environment and shapes adapted behavioral reactions. Hence, the olfactory system is complex with diverse brain areas processing the sensory input on different levels. ... -
Of Liars and Deniers: The Credibility-Concealed Information Test as a Response Time-Based Measure for Credibility Assessment in Suspects and Witnesses
(2020-02-26)There are numerous studies on polygraphs like the Concealed Information Test (CIT) that aim to detect whether a suspect possesses crime-related knowledge. In contrast, not a single psychophysiological or behavioral paradigm ... -
Off-Label-Use von Arzneimitteln in der Palliativmedizin
(2013-05-07)Es steht außer Frage, dass die gesundheitliche Versorgung unserer Gesellschaft durch den medizinischen Fortschritt in den letzten Jahrzehnten enorm gesteigert wurde. Dabei ist der Schwerpunkt dieser Entwicklung auf Heilung ... -
