2. 1. Environmental Factors of Importance in Myasthenia Gravis : Emphasis on Physical Activity

   Author : Elisabet Westerberg; Anna Rostedt Punga; Anne-Marie Landtblom; Chantal Tallaksen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myasthenia Gravis; MG subgroups; Environmental factors; Lifestyle; Physical activity; Exercise; Clinical Neurophysiology; Klinisk neurofysiologi;

   Abstract : Myasthenia Gravis (MG) is an autoimmune disease caused by antibodies directed against proteins at the neuromuscular junction (NMJ). The disturbed neuromuscular transmission induces fatigable weakness in skeletal muscles. READ MORE

4. 2. Endocannabinoid metabolism : the impact of inflammatory factors and pharmacological inhibitors

   Author : Jessica Karlsson; Christopher Fowler; Stig Jacobsson; Jürg Gertsch; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endocannabinoid; anandamide; 2-AG; fatty acid amide hydrolase; cyclooxygenase-2; prostate cancer; catabolism; inflammation; inflammatory factors;

   Abstract : The endocannabinoid (eCB) system is an endogenous signaling system consisting of ligands (referred to as endocannabinoids, eCBs), receptors and metabolic enzymes. The eCB system is involved in homeostatic control of a variety of biological functions such as neuronal signaling, mood, appetite and pathological conditions such as pain, inflammation and tumour progression.

5. 3. Neurotrophic factors and neuronal plasticity

   Author : Sten Linnarsson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The neurotrophic factors were originally discovered because of their ability to rescue neurons during a period of naturally occurring programmed cell death. This gave rise to the neurotrophic factor hypothesis which states that specific target-derived factors protect and support subpopulations of innervating neurons, thereby regulating the pattern and quantity of innervation properly for each target tissue.

6. 4. Environmental intolerance : psychological risk and health factors

   Author : Eva Palmquist; Steven Nordin; Gregory Neely; Berndt Stenberg; Michael Witthöft; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmental intolerance; stress; anxiety; depression; burnout; prognosis; recovery; spreading; coping; social support; co-prevalence; Västerbotten Environmental Health Study; idiopathic environmental intolerance; multiple chemical sensitivity; sick building syndrome; noise sensitivity; electromagnetic hypersensitivity; Psychology; psykologi; Epidemiology; epidemiologi;

   Abstract : 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. READ MORE

7. 5. Essays on Panel Data with Multidimensional Unobserved Heterogeneity

   Author : Yana Petrova; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Econometrics; Factor-Augmented Panel Regression; Interactive Effects; Unknown Factors; CCE Estimation; Principal Components;

   Abstract : This thesis contributes to econometric methodology in terms of estimation and inference in static panel data models with unobserved multidimensional heterogeneity. When not properly accounted for, unobserved heterogeneity may introduce bias into the parameter estimates associated with covariates of interest, such as treatment indicators or determinants of macroeconomic indicators.
