6. NMR studies of the amyloid beta-peptide
Sammanfattning : The Amyloid beta peptide (Ab) is related to Alzheimer’s disease and is suggested to be the molecular pathogenic species of the disease, probably through the neurotoxic effect of Ab oligomers. Here the results from biophysical studies of Ab and fragments thereof, are presented. LÄS MER
7. Microgel Interactions with Peptides and Proteins : Consequence of Peptide and Microgel Properties
Sammanfattning : Microgels are lightly cross-linked hydrogel particles in the sub-micrometer to micrometer size range with a capacity to drastically change their volume in response to changes in the external environment. Microgels have an ability to bind and store substances such as biomacromolecular drugs, notably proteins and peptides, and release them upon stimuli, making them potential candidates as drug delivery vehicles and functional biomaterials.

8. Interaction Between Antimicrobial Peptides and Phospholipid Membranes : Effects of Peptide Length and Composition
Sammanfattning : Due to increasing problems with bacterial resistance development, there is a growing need for identifying new types of antibiotics. Antimicrobial peptides constitute an interesting group of substances for this purpose, since they are believed to act mainly by disrupting the bacterial membrane, which is a fast and non-specific mechanism.

9. Ribosome and ribosomal RNA Structure : An experimental and computational analysis of expansion segments in eukaryotic ribosomal RNA
Sammanfattning : Ribosomes are large ribonucleoprotein complexes which incorporate amino acids into peptide chains during translational process in all types of living cells. The eukaryotic ribosome is larger compared to its prokaryotic counterpart. LÄS MER
10. Polymeric Nanoparticles as Carriers for Antimicrobial Peptides : Factors Affecting Peptide and Membrane Interactions
Sammanfattning : As resistance towards conventional antibiotics is becoming more pronounced, cationic antimicrobial peptides (AMPs) have received considerable attention as possible therapeutic alternatives. Thousands of potent AMPs occur in humans, animals, plants and fungi as a natural part of the immune system. LÄS MER
