  1. 6. Transmethylation, Polyamines and Apoptosis in Amyotrophic Lateral Sclerosis

    Författare :Titti Ekegren; Håkan Askmark; Cecilia Gomes-Trolin; Sten-Magnus Aquilonius; Christopher Fowler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; amyotrophic lateral sclerosis; neurodegeneration; transmethylation; polyamine; apoptosis; Neurovetenskap; Neurology; Neurologi;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a relentlessly progressive disorder characterized by degeneration of motor neurons in the cortex, brainstem and spinal cord. The patients usually die within 3-5 years after onset. The full etiology of ALS is unknown and many hypotheses have been proposed to explain the neurodegeneration. LÄS MER

  3. 7. Search for Biomarkers in ALS and Parkinson's Disease : Positron Emission Tomography and Cerebrospinal Fluid Studies

    Författare :Anders Johansson; Håkan Askmark; Lennart Persson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyotrophic lateral sclerosis; ALS; Parkinson’s disease; cerebrospinal fluid; positron emission tomography; vascular endothelial growth factor; fibroblast growth factor 2; proteomics; Fourier transform ion cyclotron resonance mass spectrometry; deprenyl-D2; PIB; FDG; L-[β11C]-DOPA; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : New biomarkers are needed to improve knowledge about pathophysiology, in order to provide earlier correct diagnosis and to follow disease progression of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD). The aim of this thesis was to find new biomarkers for these diseases. LÄS MER

  4. 8. UHV-CVD growth of Ge/Si nanostructures

    Författare :Vilma Zela; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductory physics; Fysik; Physics; Naturvetenskap; Si; Ge; Esaki diode; Halvledarfysik; Ge layer; Natural science; Ge Ilands; posiotioning;

    Sammanfattning : This thesis is based on the results concerning the epitaxial growth and characterization of silicon (Si) and germanium (Ge) nanostructures. The growth technique was the Ultra High Vacuum Chemical Vapor Deposition (UHV-CVD) that works in relatively low temperatures and low growth pressures. LÄS MER

  5. 9. Nanowire Heterostructures- Growth, Characterization and Optical Physics

    Författare :Niklas Sköld; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nano; Nanowire; photoluminescence; epitaxy; quantum dot;

    Sammanfattning : This thesis describes growth, processing, characterization and photoluminescence (PL) spectroscopy of nanowire heterostructures. The nanowires were made of III-V semiconductor materials and were produced by Au-particle assisted growth. LÄS MER
