  2. 1. Molecular Electronics : A Theoretical Study of Electronic Structure of Bulk and Interfaces

    Author : Mikael Unge; Sven Stafström; Mads Brandbyge; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; electron transport; disorder; localization; long-range correlation; organometallic magnets; interface dipole; Computational physics; Beräkningsfysik;

    Abstract : This thesis deals with theoretical studies of the electronic structure of molecules used in the context of molecular electronics. Both studies with model Hamiltonians and first principle calculations have been performed. READ MORE

  4. 2. Diffusive interactions play an important role in protein stability and mobility : Investigations of the intracellular milieu using in-cell NMR

    Author : Therese Sörensen; Mikael Oliveberg; Per Jemth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; in-cell NMR; protein-protein interactions; mobility; stability; thermodynamics; Nuclear Magnetic Resonance; stopped-flow spectroscopy; proteins; SOD1; HAH1; TTHA1718; cells; cytoplasm; humans; bacteria; ions; polyions; electrostatics; biokemi; Biochemistry;

    Abstract : Proteins are crucial for all cellular life. Every signal received by a cell, and every response to it, is mediated by proteins. Inside cells, these proteins diffusively sample each other’s surfaces, as they travel through the cytoplasm in search of their specific interaction partners. READ MORE

  5. 3. Protein stability and mobility in live cells : Revelation of the intracellular diffusive interaction organization mechanisms

    Author : Xin Mu; Mikael Oliveberg; Johan Elf; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusive interactions; macromolecular crowding; protein thermodynamic stability; protein mobility; in-cell NMR; Hofmeister series; Biochemistry; biokemi;

    Abstract : Biochemical processes inside living cells take place in a confined and highly crowded environment. As such, macromolecular crowding, one of the most important physicochemical properties of cytoplasm, is an essential element of cell physiology. READ MORE

  6. 4. Advanced computations and mass-spectrometric techniques to unravel the dynamics and interactions of proteins

    Author : Joana Costeira-Paulo; Erik Marklund; Lars Konermann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; mass spectrometry; dihydroorotate dehydrogenase; alpha-synuclein; protein structure; ion mobility; electrospray ionisation; collision cross section; lipids; gas-phase hydrogen deuterium exchange; collision induced unfolding; Biokemi; Biochemistry;

    Abstract : Proteins are an important class of biomolecules, involved in the metabolism, regulation, structure and transport in cells. Unfortunately, many diseases are caused by protein dysfunction. When proteins perform their normal function, they may interact with each other or change their conformation. READ MORE

  7. 5. The deep evolutionary roots of non-coding RNA - a comparative genomics approach

    Author : Marc Patrick Hoeppner; Anthony M. Poole; Britt-Marie Sjöberg; Jürgen Brosius; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; non-coding RNA; evolution; comparative genomics; RNA world; introns; snoRNA; miRNA; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Non-coding RNAs (ncRNA) are a diverse group of genes that do not encode proteins but function exclusively on the level of RNA and were originally suggested to be remnants of a pre-DNA stage of life known as the RNA world. More recent work, however, has uncovered a rich repertoire of previously unknown families with possible consequences for our understanding of the origin and evolution of the modern RNA infrastructure.
