The Genetics of Adaptation and Evolvability in Yeast
(2022-10-18)Evolution is the hereditary change in life forms that has shaped the divergence of all organisms that inhabit planet Earth. I used the yeast Saccharomyces cerevisiae to study how adaptive evolution increases the fitness ... -
How ship exhaust particles change cloud activity
(2024-01-08)The Arctic is experiencing surface warming rates that exceed those observed at lower latitudes. This is caused by a complex system of feedback mechanisms in the Arctic climate system and is referred to as Arctic ... -
Human Aquaporins: Production, Characterization and Interactions
(2015-11-06)Membrane proteins are essential components of the cell and responsible for the communication with the outside environment and transport of molecules across the membrane. Water transport is facilitated by aquaporins, which ... -
Hydrous iridium oxide for in-situ pH sensing: electrodeposition, properties and applications.
(2013-05-20)For heterogeneous processes, such as electrochemical reactions taking place at an elec- trode, the chemical conditions at the reaction interface can differ significantly from the bulk. Consumption of reactants leads to ... -
Identification of novel BRCA2-binding proteins that are essential for meiotic homologous recombination
(2021-01-27)Meiotic recombination is a molecular process in which the induction and repair of programmed DNA double-strand breaks (DSBs) creates genetic exchange between homologous chromosomes and thus increases genetic diversity and ... -
Implementation and development of serial synchrotron crystallography at MAX IV
(2023-10-11)Over the past decade, remarkable advancements in femtosecond X-ray free-electron lasers (XFELs) have brought about a profound transformation in structural biology. These XFELs have opened up exciting opportunities for ... -
Improving integration efficiency and precision of CRISPR/Cas9-mediated genome editing
(2023-09-07)The clustered regularly interspaced short palindromic repeats (CRISPR) – CRISPR-associated protein 9 (Cas9) system has revolutionized the field of genome engineering, providing a cost-effective and fast tool for targeted ... -
Inhibition of the MDM2/p53 Interaction Design, Synthesis and Evaluation of MDM2 Inhibitors
(2015-02-20)Numerous essential cellular processes are regulated by protein-protein interactions (PPIs) and PPIs have therefore been recognised as potential new drug targets. The transcription factor p53 is often referred to as the ... -
Inhibition of the mevalonate pathway in C. elegans: Consequences and implications
(2015-09-15)The mevalonate pathway in human is responsible for the synthesis of cholesterol and other important biomolecules such as coenzyme Q (a component of the electron transport chain in mitochondria), dolichols (important for ... -
Integrative analysis of osmoregulation in yeast Saccharomyces cerevisiae
(2014-05-06)Similar to other unicellular organisms, yeasts frequently encounter environmental stress such as heat shock, osmotic stress, and nutrition limitations, which challenge their growth potential. To survive, all living cells ... -
Interaction of Natural Organic Matter molecules with TiO2 nanoparticles: An Experimental Adsorption and Aggregation study
(2018-08-16)Mechanisms by which synthetic nanoparticles are released into natural environments and the potential impact of nanoparticles on living organisms have been discussed frequently over the past decade. Interactions of nanoparticles ... -
Interrogation of Biological Samples by ToF-SIMS using New Primary Ion Beams and Sample Preparation Methods
(2017-01-12)Mass spectrometry is a very versatile and important technique in analytical chemistry. From atomic bombs to Alzheimer’s disease, after a century of improvements and developments there are now countless applications for ... -
Intrinsically Disordered Domains of the B Cell Receptor Cell-Free Expression and Characterization by NMR
(2014-10-23)After the last twenty years of research, the occurrence of flexible proteins without a fixed three-dimensional structure are no longer considered to be rare exceptions from the structure-function paradigm. Instead, ... -
Investigation of Exocytosis for a New Paradigm of Plasticity in Biological Systems Using Electrochemistry and Mass Spectrometry Imaging
(2021-05-05)Cellular communication is a vital process and serves as the basis for complex brain functions in multicellular organisms. The majority of cellular communication is achieved via the release of specific signaling molecules, ... -
Ion Solvation in Critical Binary Aqueous Solvents Probed by Advanced Synchrotron-Based Techniques
(2016-05-20)The Poisson-Boltzmann equation is the standard tool for studying the electrostatic interactions in electrolyte solutions, although it neglects e.g. the ion size and ion-ion correlations. Even experimentally observed specific ... -
Iron catalyzed C-C coupling reactions - mechanistic investigations
(2013-05-14)The mechanism of the iron catalyzed cross coupling of aryl electrophiles with alkyl Grignard reagents was studied. The reaction proceeds via a rate-limiting oxidative addition of the aryl halide to an Fe(I) complex generated ... -
Iron or Copper? - Method Development and Mechanistic Studies on Cross-Coupling Reactions
