Investigating the Role of Lactate in Regulating Gene Expression through Epigenetic Modifications in Neuronal Cells
Manar M. Darwish
Lactate has been long thought of as a dead-end waste product of glycolysis. In the brain, recent evidence has revealed a key role of L-lactate creating a paradigm-shift in our understanding of the neuronal energy metabolism. The Astrocyte neuron lactate shuttle (ANLS) model, has shown L-Lactate as the main energy substrate delivered by astrocytes to neurons to sustain neuronal oxidative metabolism. This metabolic coupling is an essential mechanism for long-term memory formation. Experimental evidence indicates...
Advance Care Planning in der Kinderpalliativmedizin
Julia Gramm
Entscheidungen über Therapiebegrenzungen bei schwerkranken Kindern stellen eine große Herausforderung für Fachkräfte und Eltern dar und sind mit vielen Unsicherheiten verbunden. Seltene und variable Krankheitsbilder erschweren die Einschätzung der Prognose, viele Kinder konnten nie für sich selbst entscheiden, die Eltern sind emotional meist sehr belastet und es kann zu Konflikten zwischen ihnen und mit den Fachkräften kommen. Advance Care Planning (ACP) bietet einen Ansatz, wichtige Entscheidungen in einem dialogischen Prozess mit den Beteiligten umfassend vorzubereiten...
Hydrogen Combustion versus Diesel Isobaric Combustion in the Double Compression-Expansion Engine
Rafig Babayev
This thesis aims to contribute to the research and development of a new highly efficient split-cycle engine concept – the double compression-expansion engine (DCEE) – by expanding the knowledge of combustion processes suitable for this and, potentially, other modern engines, via experimental and computational studies. In this work, first, the importance of continued improvement of internal combustion engines is demonstrated by comparing the life-cycle CO2 emissions of different modes of transport, including walking and bicycling....
Experimental investigation of enhanced particle transport due to magnetic perturbations on ASDEX upgrade
Nils Leuthold
Am "Axisymmetric Divertor Experiment Upgrade" Tokamak in Garching wird an Kernfusion zum Zweck der Energiegewinnung geforscht. Nachdem in einem Tokamak Deuterium auf mehrere keV aufgeheizt wird, kann dieses aufgrund der einsetzenden Ionisierung als Plasma beschrieben werden. Magnetfelder werden dabei genutzt, um das Plasma in einer Vakuumkammer so einzuschließen, dass es thermisch isoliert ist gegenüber den Wänden der Kammer. Das Szenario, welches für zukünftige Kernkraftwerke basierend auf Kernfusion vorgesehen ist, ist die sogenannte H-Mode. In diesem...

Lisa-Florentina HammerRetrospektiver Vergleich von Katzen mit felinem Asthma und chronischer Bronchitis
Maike Susanna Grotheer
Feline asthma and feline chronic bronchitis are considered the most common chronic lower respiratory diseases in cats and are frequently referred to by the term chronic bronchial diseases. In feline asthma, a hypersensitivity reaction type I is suspected. For chronic bronchitis, the aetiology remains largely unknown. Affected cats may suffer from coughing, dyspnoea, and increased respiratory sounds. Both conditions are currently defined by the cytological cell pattern in the bronchoalveolar lavage and may differ in...
Exploring the Reactivity of Well-defined Oxide-supported MetalAlkyl and Alkylidyne Complexes via Surface Organometallic Chemistry
Aya Saidi
Surface Organometallic Chemistry (SOMC) is an excellent approach to erase the gap between homogeneous and heterogeneous catalysis by grafting the molecular organometallic complex on various oxide surfaces, forming well-defined and single-site catalysts. This strategy allows for better characterization as well as the improvement and development of existing and new catalysts. These surface species could promote a wide range of catalytic applications (i.e., metathesis of hydrocarbons, hydrogenolysis of alkanes, and olefin polymerization reactions) depending on the...
