  1. 6. On the influence of glia on neurite outgrowth from dopamine neurons in the nigrostriatal system

    Författare :Malin Saga Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dopamine; glia; astrocytes; olfactory ensheathing cells; development; ni-grostriatal; mesencephalon; Parkinson s disease; 6-hydroxydopamine;

    Sammanfattning : Interactions between glial cells and neurons are important during fetal development, in the maintenance of the normal functions in tile central nervous system (CNS), arid in response to injuries or diseases. Some of die motor disturbances in Parkinson's disease, a neurodegenerative disorder where one of the hallmarks is degeneration of dopamine (DA) neurons and concomitant depletion of DA in striatum, can be alleviated by intrastriatal grafting of embryonic DA tissue.

  3. 7. Repair of divided peripheral nerves : experimental studies in rabbit and rat

    Författare :Barbara Lutz; Pietro Giovanoli; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The general aim of this thesis was to provide new knowledge, through experimental studies, that may contribute to an improvement of the results after microsurgical peripheral nerve repair in patients.An adequate function of the human body depends, among other things, on a correctly functioning peripheral nervous system.

  4. 8. Structural and functional changes in the brain after surgically repaired median nerve injury

    Författare :Per F. Nordmark; Roland S. Johansson; Henrik Ehrsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Humans; Hand; Touch; Peripheral nerve injury; Magnetic resonance imaging; Somatosensory Cortex; Cortical plasticity; fysiologi; Physiology; handkirurgi; hand surgery;

    Sammanfattning : Despite the best available surgical repair, traumatic median nerve injury within the forearm typically causes lifelong impairment in hand function. This stems from an inadequate reinnervation of the nerves supporting sensory functions of the thumb, index and long finger, and of nerves supplying intrinsic hand muscles. LÄS MER

  5. 9. Central and peripheral adaptation after nerve repair with a synthetic biocompatible adhesive

    Författare :Thomas Landegren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The epineural repair technique is currently the accepted standard for peripheral nerve repair. However, due to the demanding nature of this method, it is not uncommon to delay or even omit action, especially in situations which are associated with extensive traumatic injuries. LÄS MER

  7. 10. Expression and Regulation of Neuropeptide Y (NPY) in the Islets of Langerhans

    Författare :Ulrika Myrsén Axcrona; Neuroendokrin cellbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; regulatory peptides; diabetes; glucocorticoids; beta cell; islet hormones; neuropeptide Y; insulin; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : This thesis deals with the expression, localization and regulation of neuropeptide Y (NPY) in the pancreatic islets of Langerhans under normal and experimental conditions. NPY is widely distributed in the mammalian nervous system and belongs to a family of closely related petides also comprising peptide YY (PYY) and pancreatic polypeptide (PP). LÄS MER
