  1. 1. Cardiovascular and respiratory effects of apnea in humans

    Författare :Johan Andersson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

    Sammanfattning : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. LÄS MER

  2. 2. β-adrenergic stimulation of VEGF gene expression : intracellular signalling pathways

    Författare :Magnus J. Fredriksson; Georg Breier; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; zoofysiologi; Zoological physiology;

    Sammanfattning : In the present study, the intracellular signalling pathway mediating ß-adrenergic stimulation of the expression of the vascular endothelial growth factor (VEGF) gene was investigated.VEGF is an activator of angiogenesis, the formation of new blood vessels, and is considered to be a major regulator of both physiologically and pathologically related angiogenesis, as well as being essential for development of the vascular system.

  3. 3. Nerve Injury Induced Pain and Spinal Cord Stimulation

    Författare :Camilla Ultenius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Neuropathic pain;

    Sammanfattning : Chronic neuropathic pain caused by injury to or disease in the nervous system is relatively common and results in major suffering, poor quality of life and incapacity. Such pain is a therapeutic challenge because a considerable portion of the patients fails to benefit from pharmacotherapy. LÄS MER

  4. 4. Quantitative and qualitative analysis of touch, cold and warmth in health, neuropathic pain and fibromyalgia

    Författare :Eva-Liz Harju; Gary B Rollman; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Ongoing pain; tactile and thermal dys function; perceived intensity; Master Scaling; perceived quality; Känsel; Smärta; fysiologisk psykologi; Fibromyalgi; psykologi; Psychology;

    Sammanfattning : The general aim of the present thesis is to examine tactile and thermal perceptual (dys)function by quantitative and qualitative tests of patients with neuropathic pain or fibromyalgia, and to compare results with those of healthy persons. A specific aim is to provide individual data for diagnostic purposes, specific to touch, cold, and warmth (profiles). LÄS MER

  5. 5. Evaluation of strategies to predict and improve early graft survival in clinical islet transpalntation

    Författare :Torbjörn Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Islets of Langerhans; clinical islet transplantation; cold storage; outcomes; PET CT; imaging; IBMIR;

    Sammanfattning : Transplantation of the islets of Langerhans as a treatment for type 1 diabetes (T1DM) is a procedure still under development. For the last decade it has been possible to obtain insulin independence by repeated infusions of islets. However, most patients must resume insulin therapy in 2-3 years. LÄS MER
