16. Extra- and intracellular electronic conductance of signals and its significance for synaptic plasticity
Sammanfattning : Electrical signals play a pivotal role in the normal function of most if not all organisms. Understanding the electrophysiological principles that govern electrical signaling is essential for insights into normal- and pathological processes in cell biology. LÄS MER
17. GNSS-aided INS for land vehicle positioning and navigation
Sammanfattning : This thesis begins with a survey of current state-of-the art in-car navigation systems. The pros and cons of the four commonly used information sources — GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information — are described. Common filters to combine the information from the various sources are discussed. LÄS MER
18. Computational problems in evolution : Multiple alignment, genome rearrangements, and tree reconstruction
Sammanfattning : Reconstructing the evolutionary history of a set of species is a fundamental problem in biology. This thesis concerns computational problems that arise in different settings and stages of phylogenetic tree reconstruction, but also in other contexts. LÄS MER
19. Regulation of human thioredoxin and glutaredoxin systems by oxidation and S-nitrosylation
Sammanfattning : The homeostasis of intracellular redox status has a crucial role in the cell survival and different processes such as DNA synthesis, gene expression, enzymatic activity, etc. This homeostasis is achieved via an intense balance between pro-oxidants and anti-oxidants. LÄS MER
20. Development of Enhanced Analytical Methodology for Lipid Analysis from Sampling to Detection : A Targeted Lipidomics Approach
Sammanfattning : This thesis covers a wide range of analytical method development for lipid analysis in complex biological samples; from sample preparation using pressurized fluid extraction (PFE) and separation with reversed phase capillary liquid chromatography (RP-LC) to detection by electrospray ionization mass spectrometry (ESI/MS) and tandem MS.The requirements for fast, reliable and selective extraction methods with minimal usage of solvents have accelerated the development of new extraction techniques.
