1. 6. Prion-infection and Cellular Signaling : Influence of scrapie-infection on lipid raft-associated proteins

   Författare :Hanna Gyllberg; Katarina Bedecs; Albert Taraboulos; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

   Sammanfattning : Prion diseases are a group of fatal neurodegenerative diseases affecting almost all mammals including humans. The diseases are caused by formation of the misfolded isoform of the cellular prion protein (PrPC) to the disease causing PrPSc. LÄS MER

3. 7. Mutant superoxide dismutase-1-caused pathogenesis in amyotrophic lateral sclerosis

   Författare :Daniel Bergemalm; Stefan Marklund; Thomas Brännström; Peter Andersen; Caterina Bendotti; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALS; SOD1; mitochondria; proteome; transgenic mice; inclusion; Clinical chemistry; Klinisk kemi; biokemi; Biochemistry; neurologi; Neurology; Clinical Chemistry; klinisk kemi; patologi; Pathology;

   Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a devastating disease that affects people in their late mid-life, with fatal outcome usually within a few years. The progressive degeneration of neurons responsible for muscle movement (motor neurons) throughout the central nervous system (CNS) leads to muscle wasting and paralysis, and eventually affects respiratory function.

4. 8. The regulation of blood coagulation by high-density lipoprotein particles

   Författare :Cecilia Oslakovic; Malmö Klinisk kemi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : High-density lipoprotein (HDL) has anti-atherogenic properties and the plasma level of HDL cholesterol correlates inversely with the risk of coronary artery disease. The atheroprotective functions of HDL can be explained by its function in the reverse cholesterol transport. LÄS MER

5. 9. Synthesis and Properties of Colloidal Zeolite

   Författare :Brian J. Schoeman; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Several zeolite phases, zeolite N-Y, N-A, ZSM-2, (hydroxy)sodalite and TPA-silicalite- 1, have been synthesized in the form of stable suspensions of discrete colloidal crystals wherein the average particle size is less than 150 nanometers and in certain cases, less than 50 nanometers, with a narrow particle size distribution, PSD. Clear homogeneous tetraalkylammonium (alumino)silicate solutions containing controlled amounts of alkali metal cations are hydrothermally treated at 100 °C without stirring and under reflux. LÄS MER

7. 10. Asymmetrical Flow Field-Flow Fractionation in the Application to Biological Macromolecules

   Författare :Cecilia Arfvidsson; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Analytisk kemi; Bioteknik; Biotechnology; biotechnology; recombinant protein production; molecular weight; Escherichia coli; ribosomes; glutenin; asymmetrical flow field-flow fractionation; multiangle light scattering;

   Sammanfattning : Asymmetrical flow field-flow fractionation (AsFlFFF) is especially useful in the application to biological macromolecules due to the absence of a stationary phase in the separation channel. As a result no upper exclusion limit occurs and low shear forces affect the sample components. LÄS MER
