  1. 1. On traumatic lesion to the spinal cord and dorsal spinal roots : factors influencing axonal regrowth across the border between the central and peripheral nervous system in the rat and man

    Författare :Tomas Lindholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Immunohistochemistry; in situ hybridization; rat; man; axotomy; regeneration; motoneuron; ; CNS; PNS; tenascin; macrophages; BBB; scar; neuregulin; ErbB3 4; semaphorin; neuropilin; VEGF; olfactory system; DRG; DRT; SNT; SNC.;

    Sammanfattning : Nerve cells are depending on their environment. Glial cells, astrocytes and oligodendrocytes in the central nervous system (CNS) make up a totally different milieu and characteristics than the distinguishing qualities of the peripheral nervous system (PNS), where the nerve cells are surrounded by Schwann cells.

  3. 2. Modelling and Simulating Demand-Responsive Transport

    Författare :Sergei Dytckov; Jan A. Persson; Paul Davidsson; Erik Jenelius; Malmö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-Demand Mobility; Demand Responsive Transport; Modelling and Simulation; Sustainability;

    Sammanfattning : Public transport is an efficient way to transport large volumes of travellers. However, there are systemic issues that make it hard for conventional public transport to provide efficient service on finer levels, like first- and last-mile problems or low-demand areas. LÄS MER

  4. 3. Computational Models in Deep Brain Stimulation : Patient‐Specific Simulations, Tractography, and Group Analysis

    Författare :Teresa Nordin; Karin Wårdell; Simone Hemm-Ode; Johannes D. Johansson; Harith Akram; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anisotropy; Deep brain stimulation DBS ; Finite element method FEM ; Patient‐specific simulation; Probabilistic stimulation maps PSM ; Tractography;

    Sammanfattning : Deep brain stimulation (DBS) is an established method for symptom relief in movement disorders like Parkinson’s disease, essential tremor (ET), and dystonia. The therapy is based on implanting an electrode with four contacts in the deep brain structures where it provides electrical stimulation, mainly impacting the nerve tracts. LÄS MER

  5. 4. Keratinocytes in tissue engineering of human skin: invitro and in vivo studies

    Författare :Camilla Fredriksson; Gunnar Kratz; Fredrik Huss; Xiao-Feng Sun; Bengt Gerdin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keratinocytes tissue engineering; Plastic surgery; Plastikkirurgi;

    Sammanfattning : Full thickness wounds, such as deep burns, need restoration of both the dermal and epidermal layers of the skin. In normal wound healing, re-epithelialization occurs by migration and proliferation of keratinocytes from the wound edges and by differentiation of stem cells from remaining hair follicles. LÄS MER

  7. 5. Mind off driving: Effects of cognitive load on driver glance behaviour and response times

    Författare :Emma Nilsson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cognitive load; visual behaviour; lead vehicle braking; traffic safety; distraction; response times; driver behaviour; intersections;

    Sammanfattning : Introduction: Safe driving requires drivers to look at relevant information in the traffic environment and react in time in case a critical event arises. Concerns exist that cognitively loading tasks might interfere with drivers’ abilities to do this. LÄS MER
