  1. 11. Idiopathic environmental intolerance attributed to electromagnetic fields : physiological and psychological aspects

    Författare :Amanda Johansson; Lena Hillert; Umeå universitet; []
    Nyckelord :electrical hypersensitivity; EHS; mobile phone; MP; heart rate variability; HRV; provocation study; radiofrequency field; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : This thesis aims to increase the knowledge on people with symptoms attributed to electromagnetic fields (EMF) by investigating the effects of EMF exposure and by additional description of the heterogeneous group of people reporting EMF-related symptoms. The effect of mobile phone (MP)-like radio frequency (RF) fields on symptoms, autonomic nervous system (ANS) parameters, short-term memory, and reaction time in persons with MP-related symptoms (MP participants) was investigated in a provocation study.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Internal carotid artery disease; cerebrovascular hemodynamics; Carotid thrombendarterectomy; Duplex ultrasound; transcranial Doppler; Internal carotid artery disease;

    Sammanfattning : Non-invasive ultrasound investigations were evaluated in patients with carotid artery stenosis in comparison with radiological disease gradations and perioperative blood pressure measurements. The aim was to assess cerebrovascular hemodynamics before, during and after carotid thrombendarterectomy (CEA) in relation to the clinical outcome of the surgical intervention. LÄS MER

  4. 13. Estrogen receptor gene activity within the brain and the relation to psychiatric disorders : mapping and function

    Författare :Marie Österlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :steroid hormone; ER system; in situ hybridization; rnRNA; ER serotonin; depression; affective disorders;

    Sammanfattning : Estrogens have for a long time been known to regulate neuroendocrine functions in the central nervous system (CNS), primarily related to reproduction. In recent years estrogens have been found to also modulate many other brain functions, for example mood and cognition. LÄS MER

  5. 14. Neural stem cell therapy and inflammation status of post-traumatic syringomyelia

    Författare :Tingting Xu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Post-traumatic syringomyelia (PTS) is a severe complication of chronic spinal cord injury (SCI) with intraspinal expanding cysts as the major pathology. PTS occurs in up to 30 % of SCI patients, and time of diagnosis is usually years after the primary injury. LÄS MER
