  2. 1. Interactions and dynamics in biophysical model systems

    Author : Erik G. Brandt; Olle Edholm; Michael Odelius; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological physics; Biologisk fysik;

    Abstract : Computer simulations of simplified model systems provide understanding of how complex biological systems behave. The simulations give detailed information about the systems, with atomistic resolution, that can be used in combination with experimental knowledge to shed light on underlying physical principles.

  4. 2. Modeling Biophysical Mechanisms underlying Cellular Homeostasis

    Author : Padideh Kamali-Zare; Hjalmar Brismar; Charles Nicholson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological physics; Biologisk fysik;

    Abstract : Cellular homeostasis is the effort of all living cells to maintain their intracellular content when facing physiological change(s) in the extracellular environment. To date, cellular homeostasis is known to be regulated mainly by time-consuming active mechanisms and via multiple signaling pathways within the cells. READ MORE

  5. 3. Dynamics of the voltage-sensor domain in voltage-gated ion channels : Studies on helical content and hydrophobic barriers within voltage-sensor domains

    Author : Christine S. Schwaiger; Erik Lindahl; Lynn Kamerlin; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; activation; deactivation; inactivation; voltage-sensor; VSD; Kv1.2- 2.1; F233; hydrophobic barrier; alpha-helix; 3 10 -helix; Biological physics; Biologisk fysik;

    Abstract : Voltage-gated ion channels play fundamental roles in neural excitability and thus dysfunctional channels can cause disease. Understanding how the voltage-sensor of these channels activate and inactivate could potentially be useful in future drug design of compounds targeting neuronal excitability. READ MORE

  6. 4. Fluorescence Studies of Membranes -- Proteins and Lipids, their Dynamics and Interactions

    Author : Johan Strömqvist; Jerker Widengren; Thorsten Wohland; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fluorescence correlation spectroscopy; cytokinesis; collision theory; protein-protein interactions; lipid dynamics; single-molecule experiment; Biological physics; Biologisk fysik;

    Abstract : In this thesis, fluorescence spectroscopy was utilized to probe protein and lipid dynamics and interactions in their native, or close to native, environments. Thereby insight could be gained into the fundamentals of bacterial cell division and the innateimmune system. A particular focus has been devoted to fluorescence fluctuations. READ MORE

  7. 5. Multidimensional Ultrasonic Standing Wave Manipulation in Microfluidic Chips

    Author : Otto Manneberg; Hans M. Hertz; Martin Wiklund; Jürg Dual; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biological physics; Biologisk fysik;

    Abstract : The use of ultrasonic standing waves for contactless manipulation of microparticles in microfluidic systems is a field with potential to become a new standard tool in lab-on-chip systems. Compared to other contactless manipulation methods ultrasonic standing wave manipulation shows promises of gentle cell handling, low cost, and precise temperature control. READ MORE
