  1. 21. Regulation of Injury Induced Schwann Cell Proliferation Schwann Cell Proliferation

    Författare :Åsa Fex Svenningsen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; estrogen; signal transduction; insulin like growth-factors; Schwann cell; peripheral; nerve regeneration; Djurfysiologi; Animal physiology; progesterone;

    Sammanfattning : The purpose of this study was to investigate injury induced proliferation of Schwann cells with emphasis of the effects of the insulin-like growth factors (IGF-I and IGF-II) and the sex hormones progesterone and estrogen. Proliferation, measured as [3H] thymidine incorporation, was studied in cultured segments of the rat sciatic nerve or through the use of the thymidine analogue bromo- deoxy-uridine (BrdU) in combination with immunocytochemistry.

  3. 22. Targeting apoptosis-inducing factor as a novel therapeutic strategy for preventing perinatal brain injury

    Författare :Juan Rodriguez; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AIF; neonatal; mouse; hypoxia-ischemia; AIF CypA complex; apoptosis; asphyxia; CHCHD4;

    Sammanfattning : Perinatal complications such as asphyxia can cause brain injuries that are often associated with subsequent neurological deficits. The mechanisms of perinatal brain injury are not fully understood, but mitochondria play a prominent role, not only due to their central function in metabolism, but also because many proteins with apoptosisrelated functions are located in the mitochondrion.

  5. 24. Injury-Induced Signalling in Arterial Smooth Muscle Cells

    Författare :Sara Moses; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GAG; Clinical biology; Klinisk biologi; proteoglycan; osteopontin; ERK; MAPK; signalling; smooth muscle cell; injury;

    Sammanfattning : The vascular wall is an active, elastic and integrated organ made up of cellular and extracellular matrix (ECM) components. It is not a static organ; the components dynamically change and reorganize in response to physiological and pathological stimuli. Vascular injury induces a complex healing process, analogous to generalised wound healing. LÄS MER

  7. 25. Development of biosynthetic conduits for peripheral nerve repair

    Författare :Aleksandra McGrath; Liudmila N Novikova; John Haycock; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biosynthetic conduit; Mesenchymal stem cells; Nerve graft; Nerve tissue engineering; Peripheral nerve injury; Schwann cells;

    Sammanfattning : Peripheral nerve injuries are often associated with significant loss of nervous tissue leading to poor restoration of function following repair of injured nerves. Although the injury gap could be bridged by autologous nerve graft, the limited access to donor material and additional morbidity such as loss of sensation and scarring have prompted a search for biosynthetic nerve transplants.
