  1. 11. Studies on Peripheral Nerve Regeneration: Microdispensing, Neurite Guidance and Galectins

    Författare :Per Gustavsson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; cytochemistry; Histology; Schwann cells; sciatic nerve; dorsal root ganglia; DRG; neurite guidance; galectins; inkjet; microdispensing; peripheral nervous system; nerve regeneration; Animal physiology; Djurfysiologi; Biotechnology; Bioteknik;

    Sammanfattning : The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. LÄS MER

  3. 12. Neurogenic and angiogenic actions of electroconvulsive seizures in adult rat brain

    Författare :Johan Hellsten; Enheten för psykiatrisk neuromodulering (PNU); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vävnadskultur; Psychiatry; clinical psychology; psychosomatics; klinisk psykologi; psykosomatik; histokemi; cytokemi; Histologi; tissue culture; histochemistry; cytochemistry; Histology; Biology; Biologi; electroconvulsive seizures; hippocampus; depression; angiogenesis; neurogenesis; Psykiatri;

    Sammanfattning : In the current thesis, the neurogenic and angiogenic response to electroconvulsive seizure (ECS)-treatment was investigated in the adult rat brain. ECS-treatment is an animal model for the antidepressant treatment electroconvulsive therapy (ECT), which is considered to be the most effective antidepressant treatment modality today, however with not yet fully understood modes of action.

  4. 13. Signalling to Activation of Cytosolic Phospholipase A2 and Arachidonate Release in Macrophages

    Författare :Gösta Hiller; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal transduction; dexamethasone; macrophages; phospholipase C; phosphatidylinositol 3-kinase; mitogen-activated protein kinases; cytosolic phospholipase A2; arachidonic acid; Histology; cytochemistry; histokemi; cytokemi; tissue culture; Histologi; vävnadskultur; histochemistry;

    Sammanfattning : Eicosanoids include prostaglandins, thromboxanes and leukotrienes, which are arachidonic acid oxygenation products. These lipids make important contributions to the signs and symptoms of inflammatory diseases. LÄS MER

  5. 14. Analysis of effector pathways in arthritis

    Författare :Nandakumar Kutty Selva; Immunologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunologi; transplantation; Genetik; cytogenetics; Arthritis; mice; monoclonal antibody; collagen type II; Histology; histochemistry; cytochemistry; Histologi; tissue culture; cytokemi; histokemi; Genetics; vävnadskultur; serologi; cytogenetik; Immunology; serology;

    Sammanfattning : Rheumatoid arthritis (RA) is a multifactorial, polygenic autoimmune disease. For effective treatment and control of RA, understanding of disease pathways and identification of genes involved are essential. Animal models are efficient tools to identify such pathogenic mechanisms and genes underlying the disease process. LÄS MER

  7. 15. Assessment of eosinophil degranulation in allergic diseases and experimental models

    Författare :Monika Malm-Erjefält; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood; histochemistry; cytochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; animal morphology; Animal anatomy; Djurs anatomi och morfologi; Haematology; cytoplasmic granules ; Hematologi; Respiratory system; extracellulära vätskor; Andningsorganen; toxikologi; farmaci; farmakognosi; Farmakologi; toxicology; pharmacy; pharmacognosy; Klinisk biologi; Pharmacological sciences; Histology; cell separation ; mice; animal models ; biological marker ; transmission electron microscopy allergy; cell degranulation ; Clinical biology; extracellular fluids; eosinophils;

    Sammanfattning : In allergic disorders, the eosinophilic granulocytes migrate to affected tissues and release granule proteins with cytotoxic, immunoregulatory, and remodeling-promoting properties. Given that degranulation is reflected by a loss in eosinophil granule density of living cells, or by cell membrane rupture and release of intact granules, these morphological changes may represent a biomarker of the allergic disease.
