  1. 1. Interaction of Calcium Ions with Lipid Membranes

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Baharan Ali Doosti; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Abstract : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

  2. 2. Removal of Metal Ions from Wood Chips during Acidic Leaching

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Anna Saltberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scandinavian softwood; spruce; calcium; diffusion coefficient; potassium; birch; Acidic leaching; eucalyptus; metal ions; oxalate;

    Abstract : Wood chips are the main source of intake of non-process elements at kraft pulp mills. It would be advantageous to decrease the content of these elements in the chips prior to pulping. READ MORE

    Abstract : Popular Abstract in Swedish Kroppens rörelser åstadkommes genom sammandragning av muskelvävnad som kan vara av två slag, glatt eller tvärstrimmig. Den senare sorten kan indelas i skelett och hjärtmuskulatur, vilka har mycket olika egenskaper trots den gemensamma benämningen. READ MORE

    Abstract : Popular Abstract in Swedish Nästan en miljon nya fall av magsäckscancer diagnostiseras årligen världen över. Även om frekvensen har fallit dramatiskt de senaste åren så är magsäckscancern fortfarande den näst vanligaste orsaken till död i cancer sett ur ett världsperspektiv. READ MORE

  5. 5. The interplay of ions in the stimulation of the pancreatic -cell

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; diabetes; pancreatic β-cells; cytoplasmic calcium; oscillations; glucose; tetrodotoxin; tolbutamide; veratridine; tetraethylammonium; quinine; cesium; H2DIDS; furosemide; transients; microfluorometry; fura-2; MQAE; calcium channels; potassium channels; sodium channels; chloride channels; Cellbiologi; MEDICINE Morphology; cell biology; pathology Cell biology; MEDICIN Morfologi; cellbiologi; patologi Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Glucose stimulation of insulin release is mediated by depolarisation of the pancreatic β-cells with accompanying entry of Ca2+ through voltage-dependent channels. An important feature of the glucose-induced depolarisation is its rhythmicity causing oscillations of the cytoplasmic Ca2+ concentration ([Ca2+]i), which trigger pulsatile release of insulin.
