   Sammanfattning : Environmental intolerance (EI) is an embracing term for a number of conditions characterized by a wide range of non-specific symptoms attributed to certain environmental exposures (e.g. pungent/odorous chemicals, residing in a certain building, electromagnetic fields and everyday sounds). EI often leads to lifestyle alterations (e. LÄS MER

3. 2. Mechanisms of Brain Damage Following Focal Cerebral Ischemia: Changes in Ion Homeostasis and the Importance of Free Radical Formation

5. 4. Astrocytic communication and cell death during metabolic depression and oxidative stress

   Författare :Christina Nodin; Göteborgs universitet; []
   Nyckelord :astrocyte; gap junction; ATP; ROS; oxidative stress; Annexin V; AIF; programmed cell death; Nrf2; scavenger; iodoacetate; SIN-1;

   Sammanfattning : Stroke is a major cause of death and adult disability in the western world. Most often, stroke is caused by the occlusion of a brain artery. Within the perfusion territory of the occluded vessel, various degrees of necrotic and delayed programmed cell death will occur if the occlusion persists, leading to expanding tissue damage. LÄS MER

7. 5. Restless legs syndrome among women with chronic widespread pain

   Författare :Romana Stehlik; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; restless legs syndrome; chronic widespread pain; females; sleep disorders; HPA-axis;

   Sammanfattning : Aims: The main aim of this thesis was to explore the prevalence, incidence and severity of Restless Legs Syndrome (RLS) in subjects with Chronic Widespread Pain (CWP). In addition, the thesis aimed to analyse the impact of pain and RLS on sleep as well as on measures of Hypothalamic–Pituitary–Adrenal (HPA)-axis function and skin sympathetic activity. LÄS MER
