  1. 1. Melanophores : cell biophysics and sensor applications

    Författare :Martin Testorf; P. Åke Öberg; Ingemar Lundström; Philip McFadden; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis deals with studies of melanophores and melanosomes by means of a physical approach. Melanophores are pigment cells that give the black colour to many vertebrates, e.g. fishes, frogs, and reptiles. LÄS MER

  3. 2. Signaling for color change in melanophores : and a biosensor application

    Författare :Annika M. Karlsson; Samuel Svensson; Margareta Wallin; Linköpings universitet; []
    Nyckelord :color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

    Sammanfattning : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. LÄS MER

  4. 3. Melanosome transfer, photoreception and toxicity assays in melanophores

    Författare :Daniel Hedberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; colour change; melanophores; melanosome; intracellular transport; pigment transfer; photoreception; toxicity assay; Roundup; glyphosate;

    Sammanfattning : Many animals such as fish and frogs have developed the ability to change colour of their skin to adapt to the environment or to signal to other individuals. This ability is due to specialised skin cells called melanophores. LÄS MER

  5. 4. Organelle movement in melanophores: Effects of Panax ginseng, ginsenosides and quercetin

    Författare :Therese Eriksson; Rolf Andersson; Samuel Svensson; Ingemar Lundström; Robert Kronstrand; Per Hammarström; Linköpings universitet; []
    Nyckelord :melanophores; Panax ginseng; ginsenosides; quercetin; organell anterograde transport; endothelin-3; mitogen activated protein kinase; protein kinase C; MEDICINE; MEDICIN;

    Sammanfattning : Panax ginseng is a traditional herb that has been used for over 2000 years to promote health and longevity. Active components of ginseng include ginsenosides, polysaccharides, flavonoids, polyacetylenes, peptides, vitamins, phenols and enzymes, of which the ginsenosides are considered to be the major bioactive constituents.

  7. 5. Probing the Nano-Bio Interface Using Surface Based Analytical Techniques

    Författare :Rickard Frost; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanotoxicology; cell membrane; nanomedicine; melanophores; QCM-D; nanomaterial; DPI; AFM; supported lipid bilayer;

    Sammanfattning : In recent years, the use of manufactured nanomaterials has been rapidly increasing in a wide range of application areas. Among others, these areas of application include cosmetics, medicine, clothing, and sporting goods. The small size of nanomaterials offers unique properties that are not possible to obtain by the same material in bulk. LÄS MER
