  1. 1. 3D super-resolution microscopy of living cells using reversibly switchable fluorophores

    Author : Andreas Bodén; Ilaria Testa; Francisco Balzarotti; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RESOLFT; 3D imaging; super-resolution; microscopy; reversibly switchable fluorescent proteins; Biological Physics; Biologisk fysik;

    Abstract : Traditional optical microscopy techniques are limited in spatial resolution due to the wave nature of light. This means that neighboring objects separated by a distance smaller than about 200 nm cannot be distinguished. READ MORE

  2. 2. Quantitative chemical imaging to study content release from single nanovesicles

    Author : Tho D. K. Nguyen; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Exocytosis; Vesicle; Mass spectrometry imaging; Electron microscopy; Fluorescence microscopy; Electrochemical analysis; NanoSIMS;

    Abstract : Cellular communication is vital for the survival of multicellular organisms. This process often relies on a highly regulated mechanism called exocytosis, which involves the release of chemical signals. During exocytosis, vesicles can fully or partially release their contents.

  3. 3. Biological effects of glucose degradation products in peritoneal dialysis fluids

    Author : Peter Jonasson; Göteborgs universitet; []
    Keywords : Peritoneal dialysis; glucose degradation products; peritonitis; peritoneum; neutrophils; macrophages; vital microscopy; microcirculation; complement; leukocyte recruitment; respiratory burst.;

    Abstract : Background: It is well known that Peritoneal dialysis (PD) fluids have biological effects on a number of cells and tissues in the peritoneum and the peritoneal cavity. However, little attention has been paid to the influence of glucose degradation products (GDPs), formed during heat-sterilization and storage of PD fluids. READ MORE

  4. 4. Nanofluidics for Static and Dynamic DNA-Protein Interaction Studies - Repair of Double-Strand Breaks from a Single-Molecule Perspective

    Author : Robin Öz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single-molecule; Protein; NHEJ; Dynamic; DNA repair; HR; Biomolecule interactions; Microscopy; Fluorescence; Nanofluidics;

    Abstract : Double-strand breaks (DSBs) is one of the most lethal forms of DNA damage. A single DSB may result in stalling of vital cellular machineries, and thus, requires immediate measures by the cell. READ MORE

  5. 5. Gastrointestinal mucosal protective mechanisms : Mudolatory effects of Heliobacter pyroli on the gastric mucus gel barrier and mucosal blood flow in vivo

    Author : Christer Atuma; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; mucus gel layer; mucosal blood flow; mucus thickness; chronic infection; rat; platelet activating factor; mast cell; nitric oxide; nitric oxide synthase; ketotifen; intra-vital microscopy; microelectrode; laser-Doppler flowmetry; L-NNA; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Abstract : The gastrointestinal mucus gel layer and blood flow are two important mechanisms for protection at the pre-epithelial and sub-epithelial levels, respectively. Helicobacter pylori might circumvent these mechanisms and elicit a chronic inflammatory response with consequent ulcers in the stomach and duodenum. READ MORE
