21. The cyanobacterial pigments scytonemin and nostodione A - Synthesis, photophysicochemical behavior and biological studies
Abstract : The natural UV-screener scytonemin is found in a plethora of cyanobacterial species. Its UV-protective ability allows the bacteria to thrive in inhospitable locations exposed to intense solar radiation. Scytonemin has a dimeric structure consisting of two 1-1' linked 3-(4-hydroxybenzylidene)cyclopenta[b]indole-2-one moieties. READ MORE

22. Chemical signals in interactions between Hylobius abietis and associated bacteria
Abstract : The pine weevil (Hylobius abietis L.) is one of the two topmost economically important insect pests in Swedish conifer forests. The damage increase in areas were the silvicultural practice is to use clear cuttings were the insects gather and breed. READ MORE

23. Contaminants of Emerging Concern in Swedish Freshwater Environments: Sources, Occurrence, and Impacts
Abstract : Contaminants of emerging concern (CECs) is one of several reasons for the deterioration of surface water quality globally, even though the CECs occur in trace concentrations. This thesis produced new CEC data through a oneyear field study for substances which occur in Sweden’s three largest lakes and their associated rivers. READ MORE

24. Tools for understanding the glycosaminoglycan biosynthesis
Abstract : For cells to function correctly within an organism, they need different systems to communicate with each other. One crucial part of cell signaling is the proteoglycans (PGs) and glycosaminoglycans (GAGs), which are macromolecules that bind different signaling molecules and proteins necessary for processes such as growth and proliferation.

25. GALIELLALACTONE ANALOGUES – SYNTHESIS AND PROPERTIES
Abstract : Cancer cells use normal cell signalling pathways in a proliferative fashion in order to prolong their own survival. Inhibition of one of the major signal proteins, STAT3 (Signal Transducer and Activator of Transcription 3) has previously been shown to induce apoptosis. READ MORE
