1. Polybrominated dibenzo-p-dioxins : Natural formation mechanisms and biota retention, maternal transfer, and effects
Sammanfattning : Polybrominated dibenzo-p-dioxins (PBDD) and dibenzofurans (PBDF) are a group of compounds of emerging interest as potential environmental stressors. Their structures as well as toxic responses are similar to the highly characterized toxicants polychlorinated dibenzo-p-dioxins. LÄS MER
2. The impact of the cytoskeleton dynamics on immune responses
Sammanfattning : Immune cells are susceptible to a variety of external stimuli that triggers cell surface receptors, leading to activation of intracellular proteins and changes in the actin cytoskeleton. The Rho-GTPases are a family of proteins that regulate several aspects of actin polymerization. LÄS MER
3. Monitoring the cellular phosphate status in bloom-forming cyanobacteria of the Baltic Sea
Sammanfattning : In the Baltic Sea dense cyanobacterial blooms occur regularly during late summer. Since the dominant bloom-forming cyanobacteria, Nodularia spp. and Apanizomenon spp. are capable of fixing atmospheric dinitrogen, the macronutrient predominantly limiting their growth is phosphorus.

4. Adaptations and constraints associated with autotrophy in microbial metabolism
Sammanfattning : Carbon dioxide (CO2) emissions from human activities are driving climate change, but the pending crisis could be mitigated by a circular carbon economy where released CO2 is recycled into commodity chemicals. Autotrophic microbes can make a contribution by producing chemicals, such as biofuels, from CO2 and renewable energy. LÄS MER
5. Wettability of modified wood
Sammanfattning : Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. LÄS MER
