  1. 36. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques

    Författare :Staffan Dryselius; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Diabetes; pancreatic beta-cells; insulin release; signal transduction; cytoplasmic calcium; oscillations; patch clamp; ATP-regulated potassium channels; voltage-dependent calcium channels; metabolism; calcium ion; strontium ion; manganese ion; wavelets; de-noising; pattern recognition; superfusion; solution changes; microscopic labelling; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. LÄS MER

  3. 37. Electrosurgical plasma-mediated ablation for application in dermal wound and cartilage debridement - Biochemical, microbiological and clinical effects

    Författare :Henrik H. Sönnergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ablation techniques; aerosol; antibacterial; arthroscopy; bacterial spread; bactericidal; bipolar radiofrequency; Candida albicans; cartilage; Coblation; debridement; electrosurgery; Escherichia coli; hydrosurgery; plume; Pseudomonas aeruginosa; Staphyloccus aureus; Streptococcus pyogenes;

    Sammanfattning : The state of matter known as plasma has in the latest decades been investigated within different areas of medical treatment. The work presented in this thesis has focused on a specific type of plasma-based electrosurgical treatment modality (Coblation®) and its biochemical, microbiological and clinical effects on treatment of cartilage and of dermal wounds.

  4. 38. A neuroimaging perspective on regulation of emotion, reward, and attention

    Författare :Frida Bayard; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Emotional symptoms and non-emotional symptoms such as inattention often co-occur. Each of these symptom domains covers symptoms that are distributed along a continuum across the population; from non-clinical levels to clinically significant psychiatric symptoms. LÄS MER

  5. 39. Regulation of neurotrophins and their receptors : molecular aspects and functional implications

    Författare :Tuija Salin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :neurotrophin; nerve growth factor; brain-derived neurotrophic factor; neurotrophin-3; neurotrophin-4; glia; gliosis; neuron; tyrosine kinase receptor; transgenic; null mutation; gene; exon; intron; mRNA;

    Sammanfattning : The aim of this work was to study the regulation of neurotrophins and their receptors in a functional aspect. The studies included analysis of neuronal and glial neurotrophin gene expression, that was investigated by using molecular biological techniques. LÄS MER

  7. 40. Real-time analysis of blood coagulation and fibrinolysis : new rheological and optical sensing techniques for diagnosis of haemostatic disorders

    Författare :Kenny Hansson; Frank Brosstad; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The haemostatic system has a dual paradoxical function in the body. It should arrest bleeding whenever needed, but also keep the blood flowing in the circulatory system without any obstructing blood clots. The system is complex with maoy intertwined processes that interact to produce a fine-tuned regulation of the performance. LÄS MER
