1. Development and application of strategies for the analysis of modification patterns in chondroitin and dermatan sulphate
Sammanfattning : Chondroitin (CS) and dermatan sulphate (DS) are socalled glycosaminoglycans (GAG) that are covalently attached to various type of proteins forming a subgroup within the diverse proteoglycan (PG) family. The PGs studied in this thesis are mostly extracellularly located and include aggrecan, biglycan and decorin. LÄS MER
2. Injectable calcium sulphate and calcium phosphate bone substitutes
Sammanfattning : Two formulations of biphasic injectable bone substitutes have been developed for the treatment of bone defects and stabilisation of fragility fractures. The first formulation consists of a calcium sulphate matrix with embedded hydroxyapatite (HA) particles to provide osteoconductivity. LÄS MER
3. Biosynthesis of Dermatan Sulphate. Enzymatic mechanism and role of cytokines
Sammanfattning : Dermatan sulphate is a prominent feature of several different proteoglycans and occurs in almost every tissue of the body. It is an unbranched polymer containing the repeating disaccharide unit of N-acetylgalactosamine and D-glucuronic acid or L-iduronic acid. LÄS MER
4. On the binding of growth-promoting polyamines to proteoglycans: Implications for growth-regulation and polycation-mediated gene transfer
Sammanfattning : Initial investigations were directed at studying the interaction between polyamines and various glycosaminoglycans (GAGs). The polyamine spermine displayed binding to dermatan sulphate (DS) and heparan sulphate (HS) with similar (Kd, 3.9 x 10-4 M) and higher (Kd, 0.37 x 10-6 M) affinity, respectively, than to DNA.

5. Volcanic Aerosols in the Upper Troposphere and Stratosphere – Aircraft- and Satellite-Based Observations
Sammanfattning : Volcanic eruptions are the largest source of variability in the stratospheric particle concentration as they inject SO2 that is subsequently converted into sulphate particles. No major perturbation of the stratospheric aerosol load has been observed since the large eruption of Pinatubo in 1991, but several moderate eruptions after 2000 have caused deviations from stratospheric background conditions.
