1. An experimental investigation of electron confinement in reversed-field pinches
Sammanfattning : Experimental studies aimed at an improved understanding ofelectron confinement in reversed-field pinch (RFP) plasmas arepresented. Different diagnostic methods have been employed:Thomson scattering and soft x-ray continuum measurements wereused to detect ektrons in the core of the plasma, x-rayemission from an insertable target was used to detect energeticelectrons in the edge region.

2. Celiac disease : complications and the role of infection in pathogenesis
Sammanfattning : Celiac disease (CD) affects about 1% of the Western population. Individuals with CD suffer increased risk of a number of comorbid conditions, including certain malignancies and diabetes mellitus type 1. The pathogenesis of CD is poorly understood. LÄS MER

4. Alzheimer disease : studies on Abeta and gamma-secretase in human brain
Sammanfattning : Alzheimer disease (AD) is a devastating neurodegenerative disorder and the most prevalent form of dementia. One hallmark of the disease is the extracellular deposition of amyloid beta-peptide (Abeta) into senile plaques in the brain. Biochemical and genetic studies reveal Abeta as a key player in AD pathogenesis. LÄS MER
5. Genetic Alterations in Pheochromocytoma and Paraganglioma
Sammanfattning : Pheochromocytomas and paragangliomas are neuroendocrine tumors that arise from neural crest-derived cells of the adrenal medulla and the extra-adrenal paraganglia. They cause hypertension due to an abnormally high production of catecholamines (mainly adrenaline and noradrenaline), with symptoms including recurrent episodes of headache, palpitations and sweating, and an increased risk of cardiovascular disease.
