  1. 1. Autonomic reactivity in muscle pain : clinical and experimental assessment

    Författare :Nebojsa Kalezic; Eugene Lyskov; Stein Knardahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autonomic reactivity; stress; chronic pain; experimental pain; back; shoulder; neck; Physiology; Fysiologi; Physiology;

    Sammanfattning : There are numerous indications of possible involvement of the autonomic nervous system in the genesis of chronic pain. The possibility exists that sympathetic activation is related to motor dysfunction and changes in sensory processing, which have otherwise been implicated in musculoskeletal disorders. LÄS MER

  3. 2. Traumatic brain injury in elderly patients

    Författare :Samuel Lenell; Per Enblad; Anders Lewén; Alfonso Lagares; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Elderly; Outcome; Standardized neurosurgical intensive care; Quality register; Prognostic factors; Secondary insults; Neurointensive care monitoring; Pressure reactivity index; Optimal cerebral perfusion pressure; Cerebral autoregulation; Neurokirurgi; Neurosurgery;

    Sammanfattning : The increase of elderly traumatic brain injury (TBI) patients constitutes a considerable challenge. The aim was therefore to specifically study elderly TBI patients with respect to patient characteristics, neurointensive care (NIC) and outcome, and to identify age specific features, which may be important for selection of patients and optimization of NIC in the elderly.

  4. 3. Neurointensive Care of Children with Severe Traumatic Brain Injury : Studies of barbiturate coma treatment, intracranial compliance, pressure autoregulation and optimal cerebral perfusion pressure

    Författare :Fartein Velle; Per Enblad; Shruti Agrawal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Children; Refractory intracranial hypertension; Barbiturate coma; Intracranial compensatory reserve; autoregulation; cerebral microdialysis.; Neurokirurgi; Neurosurgery;

    Sammanfattning : Traumatic brain injury (TBI) is among the most common causes of death and acquired disability during childhood. Management guidelines for pediatric patients are usually extrapolated from adults. Specific pediatric studies are warranted to improve the TBI management in children. LÄS MER

  5. 4. Compound Formation in Model Catalysts

    Författare :Rasmus Westerström; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2010:Westerström;

    Sammanfattning : In this thesis we have performed a systematic atomic scale characterization of model catalysts under pressures ranging from UHV to atmospheric ambient. By using a unique approach, linking UHV and high pressures studies by combining traditional electron based techniques with novel high pressure in situ probes and ab initio calculations, the surface structure of the different model catalysts could be determined under a wide range of conditions, spanning more than ten orders of magnitude in pressure.

  7. 5. Cardiovascular function in normal pregnancy and fetal growth

    Författare :Charlotte Iacobaeus; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Pregnancy is a challenge to a woman’s cardiovascular system, and extensive haemodynamic changes are required for optimal utero-placental circulation and fetal growth. The aim of this thesis was firstly to examine different aspects of vascular function in the same women longitudinally during normal pregnancy, and secondly to explore whether there is an association between maternal cardiovascular function, placental function, and fetal growth.
