  1. 1. Mathematical Models in Cellular Biophysics

    Author : Jacob Kowalewski; Hjalmar Brismar; Erik Fransén; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Calcium oscillations; Diffusion; Dopamine receptors; Mathematical models; Computer simulations; FRAP; Physics; Fysik;

    Abstract : Cellular biophysics deals with, among other things, transport processes within cells. This thesis presents two studies where mathematical models have been used to explain how two of these processes occur. Cellular membranes separate cells from their exterior environment and also divide a cell into several subcellular regions. READ MORE

  2. 2. Endoplasmic Reticulum Dynamic Structural Changes in Neurons: The Fission-Fusion Phenomena

    Author : Krzysztof Kucharz; Sektion IV; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fragmentation; fission; endoplasmic reticulum; neurons; FRAP; primary cultures; organotypic slice cultures; in vivo; in situ; calcium; fusion; NMDA receptor; 2-photon microscopy; confocal microscopy;

    Abstract : The endoplasmic reticulum (ER) is crucial for protein synthesis and protein maturation, is involved in cell stress and serves in neurons as the major intracellular Ca2+ store. Neuronal ER forms a continuous network of cisterns and tubules extending from soma to a subset of dendritic spines. READ MORE

  3. 3. Antioxidant Capacity in Fruit and Vegetables -Cultivar Variation - Storage Conditions - Human Antioxidant Status

    Author : Jessica Nilsson; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human plasma antioxidants; Brassica; strawberry; pea; cultivar; ABTS; FRAP; Total antioxidant capacity; TAC; Food and drink technology; Livsmedelsteknik;

    Abstract : The health-promoting effects of fruits and vegetables have been extensively discussed during the past decade since epidemiologic studies have shown relations between increased intake of fruit and vegetables and decreased incidences of several chronic diseases. It has been suggested that antioxidants are a main contributors to the observed effects, for example by acting as scavengers of free radicals. READ MORE

  4. 4. Mesoporous supported lipid bilayers

    Author : Maria Claesson; Chalmers University of Technology; []
    Keywords : FRAP; Lipid bilayer; Mesoporous; AFM; Vesicle; Titania; Silica; QCM-D;

    Abstract : AbstractLipid bilayers are commonly used as simplified model systems of living cell membranes. They have shown to be important components in the development of biosensing devices where the bilayer acts as a host for transmembrane proteins, such as ion channels, that are utilized as sensing elements.

  5. 5. Applications of hydrodynamic forces for membrane chromatography

    Author : Björn Johansson Fast; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Membrane chromatography; FRAP; Protein accumulation; Supported lipid bilayer; Microfluidics; SEEC; Diffusion; Hydrodynamic forces; Label-free;

    Abstract : Membrane proteins are proteins that reside in the cell membrane. Due to their position in the cell membrane, the barrier between the cell interior and exterior, they are vital to cell signaling. Moreover, the presence of membrane proteins in the cell's signaling pathways make membrane proteins important drug targets. READ MORE
