    • Aspects of the regulation of human sperm motility 

      Leijonhufvud, Pär K G (Inst för kvinnors och barns hälsa / Dept of Women's and Children's Health, 1998-04-02)
      In this thesis I address some of the possible causes for oligozoospermia and low sperm motility, two factors that, singly or in combination, are often seen in cases of male subfertility. In the first study we evaluated the ...
    • The wind of change : individuals change when technology change 

      Fridell, Kent (Institutionen för klinisk vetenskap / Department of Clinical Sciences, 2007-11-26)
      The production of digital images has been well-known within radiology for many years through its use of modalities such as computer tomography, ultrasound and magnetic resonance tomography. During the latter part of the ...
    • Effects of an expanded rehabilitation programme in patients with ischemic heart disease 

      Edström Plüss, Cathrine (Institutionen för kliniska vetenskaper, Danderyds sjukhus / Department of Clinical Sciences, Danderyd Hospital, 2009-11-12)
      The effects of expanded cardiac rehabilitation (ECR) after coronary artery by-pass surgery or myocardial infarction (MI) on medical risk markers, cardiovascular (CV) morbidity and hospitalizations due to symptoms of CV ...
    • The insulin-like growth factor system : effects of circulating proteases 

      Gustafsson, Sara (Institutionen för kvinnors och barns hälsa / Department of Women's and Children's Health, 2005-08-18)
      The insulin-like growth factor-I and -II (IGF-I/-II) are peptide hormones important for growth and metabolism. They stimulate cell proliferation and differentiation and inhibit apoptosis. In addition, they have insulin-like ...
    • Structure determination of Methanocaldococcus jannaschii nucleoside kinase 

      Arnfors, Linda (Biovetenskaper och näringslära / Biosciences and Nutrition, 2005-09-22)
      All organisms can be divided into the tree kingdoms of life: Archaea, Bacteria and Eukarya. Archaeal organisms are often found to exhibit, compared to human perspectives, extreme environments, such as high temperature, ...
    • Unstimulated human whole saliva flow rate in relation to hyposalivation and dental caries 

      Flink, Håkan (Institutionen för odontologi / Department of Odontology, 2005-04-08)
      Introduction: Salivary secretion is influenced by a large number of factors, including the circadian rhythm, making the detection of reduced salivary flow (hyposalivation) difficult. This is important since severely reduced ...
    • Discovery and management of child allergy from the parent perspective 

      Gunnarsson, Nina (Institutionen för neurobiologi, vårdvetenskap och samhälle / Department of Neurobiology, Care Sciences and Society, 2007-05-11)
      The overall objective of this thesis is to extend the knowledge and deepen the understanding of care-givers management of child allergy, especially of suspected food allergy. This is done by describing and exploring how ...
    • Analysis of different forms of locomotor behavior in lamprey 

      Islam, Salma Sanzida (Institutionen för neurovetenskap / Department of Neuroscience, 2007-05-25)
      The ability to locomote, that is move actively in space, is characteristic of the animal kingdom. Many species are capable of different forms of locomotion. They include forward and backward locomotion, fast and slow ...
    • Early function of KCC2 and Wnt genes : cytoskeletal effects in neural stem cells 

      Horn, Zachi (Institutionen för kvinnors och barns hälsa / Department of Women's and Children's Health, 2008-09-19)
      From closure of the neural tube until formation of neuronal networks, cells undergo several crucial changes which depend on the expression of many important molecules. GABA, the principal inhibitory neurotransmitter in ...
    • Serodiagnostics of schistosomiasis using keyhole limpet hemocyanin (KLH) as antigen 

      Thors, Cecilia (Mikrobiologiskt och Tumörbiologiskt Centrum (MTC) / Microbiology and Tumor Biology Center (MTC), 2006-04-20)
      The diagnostics of invasive helminth infections is often indirect and based on antibody detection in serum specimens from infected individuals. This is the case in schistosomiasis (bilharzia) where no excreted eggs can be ...
    • Diabetes, physical activity and endometrial cancer 

      Friberg, Emilie (Institutionen för mikrobiologi, tumör- och cellbiologi / Department of Microbiology, Tumor and Cell Biology, 2006-11-22)
      Accumulating evidence suggests that hyperinsulinemia, in the context of insulin resistance, is associated with carcinogenesis. Physical activity is involved in the regulation of metabolic and hormonal pathways and is an ...
    • Biosynthesis and biological role of leukotrienes in B lymphocytes 

      Mahshid, Yilmaz (Institutionen för medicinsk biokemi och biofysik (MBB) / Department of Medical Biochemistry and Biophysics, 2006-11-27)
      Leukotrienes (LT) are potent lipid mediators, synthesized from arachidonic acid (AA) upon cell activation. The essential enzyme for leukotriene biosynthesis is 5-lipoxygenase (5-LO), converting AA, through a two step process ...
    • Gene expression in human skeletal muscle : effects of activity, fibre type and inheritance for diabetes 

      Ahlsén, Maria (Institutionen för fysiologi och farmakologi / Department of Physiology and Pharmacology, 2006-04-07)
      One fundamental underlying risk factor for the development of non-insulin dependent (type 2) diabetes mellitus is insulin resistance, which 80-90% of all type 2 diabetic patients suffer from. Risk factors for insulin ...
    • Dissection of HIV-1 Env-specific B cell responses in non-human primates 

      Sundling, Christopher (Institutionen för mikrobiologi, tumör- och cellbiologi / Department of Microbiology, Tumor and Cell Biology, 2010-04-27)
      It has been almost 30 years since the identification of HIV as the causative agent of AIDS. Despite considerable efforts to halt the spread of the virus, the epidemic continues in many parts of the world. The most efficient ...
