  1. 6. N-complexes and Categorification

    Författare :Djalal Mirmohades; Volodymyr Mazorchuk; Steffen Oppermann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Homological algebra; Category theory; Triangulated categories; K-theory; Hopfological algebra; Mathematics; Matematik;

    Sammanfattning : This thesis consists of three papers about N-complexes and their uses in categorification. N-complexes are generalizations of chain complexes having a differential d satisfying dN = 0 rather than d2 = 0. Categorification is the process of finding a higher category analog of a given mathematical structure. LÄS MER

  2. 7. Asymmetric Hydrogenations of Imines, Vinyl Fluorides, Enol Phosphinates and Other Alkenes Using N,P-Ligated Iridium Complexes

    Författare :Jarle Sidney Diesen; Pher G. Andersson; Kálmán J. Szabó; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Organic chemistry; Catalysis; Asymmetric; Hydrogenations; Reductions; Alkenes; Imines; Vinyl fluorides; Enolphosphinates; Transition metal; Complexes; Iridium; Organisk kemi; Chemistry; Kemi;

    Sammanfattning : The research described in this thesis is directed toward the efficient, enantioselective synthesis of chiral products that have useful functionality. This goal was pursued through catalytic asymmetric hydrogenation, a reaction class that selectively introduces one or two stereocenters into a molecule in an atom-efficient step. LÄS MER

  3. 8. Prokaryotic respiratory supercomplexes : Studies of interactions between complexes III and IV

    Författare :Olga Stah; Pia Ädelroth; Petra Hellwig; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bioenergetics; membrane protein; bacterial respiration; electron transport chain; supercomplex; cytochrome c oxidase; membrane-anchored cytochrome c; cytochrome bc1 complex; electron transfer; proton transfer; time-resolved spectroscopy; apoptosis; biokemi; Biochemistry;

    Sammanfattning : Respiratory processes for cellular energy conversion are carried out by the membrane-associated enzymes of the electron transfer chain (ETC). In recent years there has been emerging data showing that the members of the ETC organize into higher-level assemblies called supercomplexes (SCs) whose functional relevance is not yet fully understood.

  4. 9. Coordination Chemistry of Monocarboxylate and Aminocarboxylate Complexes at the Water/Goethite Interface

    Författare :Katarina Norén; Per Persson; Staffan Sjöberg; Stephan J. Hug; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acetate; benzoate; adsorption; surface complex; ternary surface complexes; ATR-FTIR spectroscopy; EXAFS spectroscopy.; cyclohexanecarboxylate; sarcosine; MIDA; EDDA; EDTA; gallium III ; goethite; mineral surface; Chemistry; Kemi;

    Sammanfattning : This thesis is a summary of five papers with focus on adsorption processes of various monocarboxylates and aminocarboxylates at the water/goethite interface. Interaction of organic acids at the water/mineral interfaces are of importance in biogeochemical processes, since such processes have potential to alter mobility and bioavailability of the acids and metal ions.

  5. 10. Proximity Ligation and Barcoding Assays : Tools for analysis of proteins and protein complexes

    Författare :Di Wu; Masood Kamali-Moghaddam; Ulf Landegren; Ola Söderberg; Jörg Hoheisel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proximity ligation assay; proximity barcoding assay; sensitive; in situ; multiplex; profiling; amyloid-beta; MARK; tau; CSF; biomarker; protein complexes; Alzheimer’s disease; amyotrophic lateral sclerosis; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Proteins are fundamental structural, enzymatic and regulatory components of cells. Analysis of proteins, such as by measuring their concentrations, characterizing their modifications, and detecting their interactions, provides insights in how biological systems work physiologically or pathologically at the molecular level.
