  4. 2. Atrial Fibrillation. Modulation of the atrial fibrillatory frequency. A non-invasive approach

    Author : Carl Meurling; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elektrofysiologi; Förmaksflimmer; arytmi; Cardiovascular system; Kardiovaskulära systemet; non-invasiv;

    Abstract : Aim: To non-invasively detect and explore the changes in atrial fibrillatory cycle length (i.e. changes in the atrial refractory period) in humans with chronic atrial fibrillation (CAF) following autonomic modulation and pharmacological intervention. READ MORE

  5. 3. Conformational Changes during Potassium-Channel Gating

    Author : Jakob Renhorn; Fredrik Elinder; David Engblom; Stephan Pless; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ion-channel; electrophysiology; neuron; Jonkanal; neurologi; elektrofysiologi; neuron; aktionspotential;

    Abstract : Voltage-gated ion channels have a paramount importance in many physiological processes such as cell-to-cell communication, action potential-propagation, and cell motility. Voltage-gated ion channels are characterized by their ability to sense membrane voltage and to greatly change channel activity in response to small changes in the voltage. READ MORE

  6. 4. Quantitative bioimaging in single cell signaling

    Author : Kristoffer Bernhem; Hjalmar Brismar; Anita Aperia; Lena Scott; Christian Eggeling; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Super resolution imaging; fluoresence; bioimaging; cells; FRET; cluster analysis; labeling; image analysis.;

    Abstract : Imaging of cellular samples has for several hundred years been a way for scientists to investigate biological systems. With the discovery of immunofluorescence labeling in the 1940’s and later genetic fluorescent protein labeling in the 1980’s the most important part in imaging, contrast and specificity, was drastically improved.

  7. 5. From Static Structures to Free Energy Landscapes: Characterizing Conformational Transitions in Biological Macromolecules

    Author : Cathrine Bergh; Erik Lindahl; Gerhard Hummer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Protein conformational transitions; molecular dynamics simulations; statistical mechanics; ion channels; Proteinkonformationsövergångar; molekyldynamiksimuleringar; statistisk mekanik; jonkanaler;

    Abstract : To be alive means to temporarily counteract the fundamental dispersive driving force described by the second law of thermodynamics, eventually leading all systems to decay and disorder. In cells, this task is partly carried out by proteins - small specialized molecular machines that utilize free energy to maintain the proper functioning of the cell. READ MORE
