  1. 1. How do metamorphic fluids move through rocks? : An investigation of timescales, infiltration mechanisms and mineralogical controls

    Författare :Barbara I. Kleine; Alasdair D. L. Skelton; John C. Schumacher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metamorphic fluid flow; fluid-rock interaction; fluid infiltration mechanisms; fluid flux rates; thermodynamic modeling; reaction front propagation; fluid flux calculation; Geology; geologi;

    Sammanfattning : This thesis aims to provide a better understanding of the role of mountain building in the carbon cycle. The amount of CO2 released into the atmosphere due to metamorphic processes is largely unknown. LÄS MER

  3. 2. Immunological and inflammatory mechanisms in ocular allergy with special reference to vernal keratoconjunctivitis : clinical and experimental studies

    Författare :Per Montan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :allergic conjunctivitis; allergen challenge; atopy; conjunctival biopsy; eosinophils; ECP; IgE; immunohistochemistry; inflammation; interleukins; T-cells; tears; vernal keratoconjunctivitis;

    Sammanfattning : Ocular allergy encompasses a wide range of conditions, most of which implicate IgE in the pathogenesis. In contrast to the benign nature of seasonal allergic conjunctivitis (SAC), the less common chronic eye diseases vernal and atopic keratoconjunctivitis (VKC and AKC) are severe and debilitating disorders.

  4. 3. Aspects of inflammation in chronic obstructive pulmonary disease : a clinical study

    Författare :Magnus J Löfdahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Chronic pbstructive pulmonary disease; bronchoscopy; bronchoalveolar lavage; inflammation; flow cytometry; bronchial biopsies;

    Sammanfattning : Development of chronic obstructive pulmonary disease (COPD) involves an amplified inflammatory response to tobacco smoke that results in a limitation of airflow. At present, the mechanisms underlying these inflammatory processes are not fully understood and insight into these mechanisms could be obtained through comparison of the processes in patients with COPD and appropriate controls.

  5. 4. Developing brain and systemic inflammation: a "Toll-like" link with consequences

    Författare :Amin Mottahedin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; developing brain; neonatal brain injury; hypoxia-ischemia; inflammation; infection; Toll-like receptor; choroid plexus; neuroimmunology; Mitochondria;

    Sammanfattning : The developing brain is vulnerable to external insults, and perinatal brain injury (PBI) is a major cause of life-long neurological syndromes such as cerebral palsy. Currently, no pharmaceutical intervention is available. Hypoxia/ischemia (HI), infections and inflammation are implicated in the pathogenesis of PBI. LÄS MER

  7. 5. On Neutrophil and Platelet Adhesive Interactions in Septic Lung Injury

    Författare :Asad Muhammad; Kirurgi; []
    Nyckelord :Leukocytes; chemokines; platelets; lung; sepsis;

    Sammanfattning : Sepsis induced by intestinal perforation is a life-threatening illness and is a frequent cause of leukocyte-mediated lung injury. Although antimicrobial therapy has been the central clinical strategy for these patients, the survival rates in such patients are still very low because of their impaired host defense mechanisms.
