  1. 16. Isolation and characterization of adult neural stem cells

    Författare :Clas B Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Intermediate filaments; GFAP; nestin; scar formation; regeneration; rodent and human neural stem cells; multipotency.;

    Sammanfattning : Injury to the central nervous system (CNS) is one of man's most handicapping situations resulting in severe functional impairment and in some cases a vegetative state where life is supported artificially. The brain and spinal cord, constituting the CNS, have been viewed for decades as having limited capacity of regeneration with no neurogenesis in the adult. LÄS MER

  2. 17. On optic nerve injury : Experimental studies on axonal regeneration in the adult mammalian CNS

    Författare :Marcus Ohlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Astroglia; axon; degeneration; glial scar; immunohistochemistry; macrophage; methylprednisolone; microglia; neurosurgery; optic nerve; rat; regeneration and visual evoked potentials;

    Sammanfattning : Optic nerve injury may occur after a trauma to the head and in many cases it causes partial or total blindness. Today, these patients cannot be offered any specific treatment to restore visual function. LÄS MER

  3. 18. 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 :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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.

  4. 19. Infarct size and myocardial function : A methodological study

    Författare :Lene Rosendahl; Jan Engvall; Thor Edvardsen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The size of a myocardial infarction (MI) and the concurrent effect on left ventricular (LV) function are essential for decisions regarding patient care and treatment. Images produced with the late gadolinium enhancement (LGE) technique visualize the scar with high spatial resolution. LÄS MER

  5. 20. Cardiopulmonary resuscitation in Sweden – yesterday, today and tomorrow

    Författare :Anneli Strömsöe; Högskolan Dalarna; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : In Sweden, the reported incidence and outcome of out-of-hospital cardiac arrest (OHCA) vary between counties. In the mid -1980s, a national programme in cardiopulmonary resuscitation (CPR) was developed and rescuers have been educated in CPR. Since 1990, Swedish OHCA data are to be reported to the Swedish Cardiac Arrest Register (SCAR). LÄS MER
