  2. 1. Selective wavelength pupillometry to evaluate outer and inner retinal photoreception

    Author : Aki Kawasaki; Fatima Pedrosa Domellöf; Bertil Lindblom; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pupil; pupil light reflex; melanopsin; photoreceptor; intrinsically photosensitive retinal ganglion cell; oftalmiatrik; Ophtalmology;

    Abstract : PurposeIntrinsically photosensitive retinal ganglion cells (ipRGCs) express a unique photopigment called melanopsin. Capable of direct phototransduction, the ipRGCs are also influenced by rods and cones via synaptic inputs. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. Equilibrium User Centred Lighting Design Towards the development of a lighting design that is individually psychologically, physiologically and visually supportive

    Author : Monica Säter; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Psychological; physiological and visual support.; User centred lighting design;

    Abstract : Why and in what way should daylight and artificial light be designed for the indoor environment in order to fulfil goals about visual comfort and light-related health? When the outdoor and indoor interactions of man, light, colour and space (MLCS) are compared to one other, the spectral component plays the decisive role (Hollwich 1979, p. 90). READ MORE

  6. 4. Calcium signaling and network activity : mathematical modeling and molecular mechanisms

    Author : Erik Smedler; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The calcium (Ca2+) ion is a versatile second messenger present in all cells. It is involved in such diverse processes as cell division, differentiation, vesicle transport and muscle contraction. Its widespread applicability is partially explained by its wide temporal and spatial dynamics. READ MORE
