  1. 6. On the Causal Mechanisms of Stuttering

    Författare :Per A Alm; Lund Neurologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; stuttering; neurofysiologi; neuropsykologi; neurophysiology; Neurologi; dystonia; neuropsychology; Neurology; basal ganglia;

    Sammanfattning : Stuttering is one of the most common speech disorders. However, the etiology is poorly understood, and is likely to be heterogeneous. The aim of this thesis was to clarify causal mechanisms, focusing the brain. LÄS MER

  3. 7. Mechanisms of tumor microenvironment in promoting metastasis

    Författare :Patrik Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tumor tissues contain diverse cell populations that relentlessly cross-communicate with each other in the tumor microenvironment. In addition to malignant cells, infiltration of other host cells including inflammatory cells, fibroblasts, and cells in the vessel walls in tumors significantly contribute to tumor growth and metastasis.

  4. 8. Mechanisms of Escherichia coli induced transepithelial neutrophil migration

    Författare :Gabriela Godaly; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; UTI; mucosa; cytokine receptors; inflammation; neutrophils; chemotaxis; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Mucosal infections trigger an inflammatory response that includes the secretion of cytokines and the recruitment of neutrophils to the infected site. This thesis describes studies examining the molecular mechanisms of neutrophil migration to sites of mucosal bacterial infection. Escherichia coli (E. LÄS MER

  5. 9. Catalytic mechanisms and evolution of leukotriene A4 hydrolyse

    Författare :Fredrik Tholander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inflammation is the first response of the body to infection or physical irritation. This response can potentially trigger the whole immune system but in the initial stage mainly involves leukocytes of the innate immune system and a complex cascade of chemical mediators, which by different means control, maintain and resolve the process.

  7. 10. Hypoxia inducible factor 1alpha : molecular mechanisms of regulation

    Författare :William J Wilson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Hypoxia-Inducible Factor 1alpha (HIF-1alpha) is an important protein in the homeostatic control of genes in response to low oxygen, or hypoxia. It is thus also a key factor in the regulation of angiogenesis in response to hypoxia, including induction of vascular endothelial growth factor (VEGF) gene expression. LÄS MER
